Equity-financed banking

My dream of equity-financed banking may be coming true under our noses. In "the Uberization of banking" Andy Kessler at the WSJ reports on SoFi, a "fintech" company. The article is mostly about the human-interest story of its co-founder Mike Cagney. But the interspersed economics are interesting.

SoFi started by making student loans to Stanford MBAs, after figuring out that the default rate on such loans is basically zero. It

has since expanded to student loans more generally and added mortgages, personal loans and wealth management. Mr. Cagney says SoFi has done 150,000 loans totaling $10 billion and is currently at a $1 billion monthly loan-origination rate. 

Where does the money come from?

SoFi doesn’t take deposits, so it’s FDIC-free. ... Instead, SoFi raises money for its loans, most recently $1 billion from SoftBank and the hedge fund Third Point, in exchange for about a quarter of the company. SoFi uses this expanded balance sheet to make loans and then securitize many of them to sell them off to investors so it can make more loans

Just to bash the point home, consider what this means:

• A "bank" (in the economic, not legal sense) can finance loans, raising money essentially all from equity and no conventional debt. And it can offer competitive borrowing rates -- the supposedly too-high "cost of equity" is illusory.
   
• There is no necessary link between the business of taking and servicing deposits and that of making loans. Banks need not (try to) "transform" maturity or risk.
   
• To the extent that the bank wants to boost up the risk and return of its equity, it can do so by securitizing loans rather than by borrowing. (Securitized loans are not leverage -- there is no promise of your money back when you want it. Investors bear any losses immediately and without recourse.)
   
• Equity-financed banking can emerge without new regulations, or a big new Policy Initiative.  It's enough to have relief from old regulations ("FDIC-free").
   
• Since it makes no fixed-value promises, this structure is essentially run free and can't cause or contribute to a financial crisis. 

More. SoFi does not use the standard methods of evaluating credit risk:

Instead of relying on notoriously inaccurate backward-looking FICO scores, SoFi is “forward-looking.” That means asking basic questions—“Do you make more money than you spend?”—and calibrating where applicants went to college, how long they’ve been employed, how stable their income is likely to be over time.

Why can’t banks do this? Because if you use depositor money for loans, as all banks do, you fall under the jurisdiction of the Federal Deposit Insurance Corp. and the Community Reinvestment Act,...

And Basel and the FSOC and the Fed and so forth. FICO score based mechanical lending standards are also demanded by government-backed securitizers Fannie and Freddie.

Yes, bank "safety" regulations demand that banks purposely lend to people that one can pretty clearly see will not pay it back, and demand that they do not lend money to people that one can pretty clearly see will pay it back.

Now, what will the regulatory response be to this sort of innovation? The right answer, of course, should be hosannas: You have introduced run-free banking, that solves all the financial-crisis worries that 90 years of bank regulation could not solve. Let this spread, and the army of bank regulators, lobbyists, lawyers, and associated politicians can all go, well, drive for Uber.

Somehow I doubt that will be the response from foresaid army. And SoFi might well want to invest in its own lawyers, lobbyists and politicians in today's America.

Rather than by the FDIC, SoFi is monitored by the Consumer Financial Protection Bureau. The overbearing regulator that was Elizabeth Warren’s brainchild thus far hasn’t come down on SoFi—the CFPB is perhaps too preoccupied with using “disparate impact” analysis of old-school auto-loan businesses to focus on a relatively exotic, app-based form of banking. But Mr. Cagney should watch his back.

Indeed he should. In today's rather rule-free environment, the CFPB -- or Department of Justice -- might just discover it doesn't like the demographics of Stanford MBAs as target borrowers.

He’d like to get a national lending license, but that would entail federal-oversight entanglements he’d rather avoid.

If he can.

A little puzzle crops up at the end. For now, I gather SoFi does not issue public equity. The plan for expansion is

insurance companies and sovereign-wealth funds might rent him their balance sheets. 

I'm not sure what "rent a balance sheet" means, but it sounds a lot like private equity or long term debt.  It would be even better for stability and low cost to issue public equity, which is liquid -- investors who need money fast can sell. But public equity comes with its own regulatory scrutiny, and perhaps even that is too much for innovation these days.

Blinder on Trade

Alan Blinder has an excellent op-ed in the WSJ on trade. It's hard to excerpt as every bit is good.

1. Most job losses are not due to international trade. Every month roughly five million new jobs are created in the U.S. and almost that many are destroyed, leaving a small net increment. International trade accounts for only a minor share of that staggering job churn. ...

2. Trade is more about efficiency—and hence wages—than about the number of jobs. You probably don’t sew your own clothes or grow your own food. Instead, you buy these things from others, using the wages you earn doing something you do better.  ...

3. Bilateral trade imbalances are inevitable and mostly uninteresting. Each month I run a trade deficit with Public Service Electric & Gas. They sell me gas and electricity; I sell them nothing....

4. Running an overall trade deficit does not make us “losers.”...

5. Trade agreements barely affect a nation’s trade balance. ..a nation’s overall trade balance is determined by its domestic decisions, not by trade deals... America’s chronic trade deficits stem from the dollar’s international role and from Americans’ decisions not to save much, not from trade deals. Trade deficits are not a major cause of either job losses or job gains. ...trade makes American workers more productive and, presumably, better paid.

One could say much more. Trade is not a "competition," for example. But,  having done this sort of thing, I'm sure lots of other good bits are on the cutting room floor.

Alan is more sympathetic to government "help" to trade losers, which I agree sounds nice if it were run by the benevolent and omniscient transfer payment planner, but I think works out poorly in practice when we look at the success or failure of actual trade adjustment programs. But that is a small nitpick.

Alan closes by wishing that Bernie Sanders and Donald Trump understood these simple facts a bit better. I think his list of politicians needing enlightenment could be a little longer. But he's courageous enough for speaking the kind of heretical truth that will come back to haunt him should he ever want a government job.

Obtaining a patient signature on the Treatment Plan Estimate . . . helping you create a more efficient workflow

I moderated my first online Dentrix user meeting last Friday and it was AWESOME! It’s called Freestyle Friday and it is open Q&A, which means YOU get to ask the questions during the live event and I get to help you solve it.

One of the most popular questions was about signing treatment plan estimates when you are paperless. This office was printing the estimate, having the patient sign it and then scanning it into the Document Center. I asked the participant why the office didn’t like this option and the answer was, “It is just so time-consuming.” Let’s look at some alternatives to being more efficient.

I gave this office two options to try and they can go back to their office and see which way works best for them. My preferred way is always not the best way for the office … which is why I love Dentrix so much as it gives a few different alternatives so you can choose.

Here are your options for obtaining an electronic signature on your treatment plan estimates. Take note that even if you are not paperless, you might find this workflow extremely helpful.

• The first option is to do a “virtual print” to the Dentrix Document Center and then have the patient sign inside of the Document Center. You can find step-by-step instructions on how to do this by reading my blog titled, “A Little Known Secret”. After you have pulled the treatment plan into the Document Center, you can make notes about the agreement and then have the patient sign electronically. If you click on Edit > Sign Document or click on the icon for Sign Document, then you can have the patient sign the document in the Document Center. This will lock up the document to prevent any editing or accidental deleting.
• The next option is to attach an electronic signature directly to the Treatment
  
  Plan case. Highlight a treatment case in the Treatment Plan module or Treatment Plan panel in the patient chart, then click on the Settings tab at the bottom of the panel. When you scroll all the way down, you can create or edit the consent forms you would like to use in your office. If you click on the Supporting Information tab just above that, you can attach a selected consent form to your case. When you do this, it will open a new window to prompt you to have the patient sign. After you have the patient sign using an electronic signature device, click on Save and Close. It will automatically save a copy of the consent form along with the signatures in the Document Center.

The main difference between these two options is that the first option will save an exact copy of the Treatment Plan estimate with which the patient leaves. The benefit of this is that you can re-print it for the patient later or review it over the phone and you have the exact copy he or she does. The second option does not save a visual picture of the treatment plan estimate, only the consent form and signatures. You choose what is best for your practice.

Lessons Learned I

I spent last week traveling and giving talks. I always learn a lot from this. One insight I got:  Real interest rates are really important in making sense of fiscal policy and inflation.

Harald Uhlig got me thinking again about fiscal policy and inflation, in his skeptical comments on the fiscal theory discussion, available here. At left, two of his graphs, asking pointedly one of the standard questions about the fiscal theory: Ok, then, what about Japan? (And Europe and the US, too, in similar situations. If you don't see the graphs or equations, come to the original.) This question came up several times and I had the benefit of several creative seminar participants views.

The fiscal theory says
 \[ \frac{B_{t-1}}{P_t} = E_t \sum_{j=0}^{\infty} \frac{1}{R_{t,t+j}} s_{t+j} \]
 where \(B\) is nominal debt, \(P\) is the price level, \(R_{t,t+j}\) is the discount rate or real return on government bonds between \( t\) and \(t+j\) and \(s\) are real primary (excluding interest payments) government surpluses. Nominal debt \(B_{t-1}\) is exploding. Surpluses \(s_{t+j}\) are nonexistent -- all our governments are running eternal deficits, and forecasts for long-term fiscal policy are equally dire, with aging populations, slow growth, and exploding social welfare promises. So, asks Harald, where is the huge inflation?

I've sputtered on this one before. Of course the equation holds in any model; it's an identity with \(R\) equal to the real return on government debt; fiscal theory is about the mechanism rather than the equation itself. Sure, markets seem to have faith that rather than a grand global sovereign default via inflation, bondholders seem to have faith that eventually governments will wake up and do the right thing about primary surpluses \(s\). And so forth. But that's not very convincing.

This all leaves out the remaining letter: \(R\). We live in a time of extraordinarily low real interest rates. Lower real rates raise the real value surpluses s. So in the fiscal theory, other things the same, lower real rates are a deflationary force.

The effect is quite powerful. For a simple back of the envelope approach, we can apply the Gordon growth formula to steady states. Surpluses \(s\) grow at the rate \(g\) of the overall economy. So, in steady state terms,
 \[ \frac{B_{t-1}}{P_t s_t} = E_t \sum_{j=0}^{\infty} \frac{(1+g)^j}{(1+r)^j} \approx \frac{1}{ r - g} \]
\[ \frac{P_t s_t}{B_{t-1}}  \approx  r - g \; \; (1) \]
(and exact in continuous time). The left hand side is the steady state ratio of surpluses to debt. The right hand side is the difference between the real interest rate and the long-run growth rate.

So, with (say) a 2% growth rate g, and a 4% long-run interest rate r, surpluses need to be 2% of the real value of debt. But suppose interest rates decline to 3%. This change cuts in half the needed long-run surpluses! Or, holding surpluses constant, if long-run interest rates fall to 3%, the price level falls by half.

You can see the punchline coming. Long term real interest rates are really low right now. If anything, we're flirting with \(r \lt g\), the magic point at which governments can borrow all they want and never repay the debt.

With this insight, Harald should have been asking of the fiscal theory, where is the huge deflation? And the answer is, well, we're sort of there. The puzzle of the moment is declining inflation and even slight deflation despite all our central bankers' best efforts.

Pursuing this idea, there is a larger novel story here about growth, interest rates, and inflation.

Obviously, there is an opposite prediction for what happens when real interest rates rise. Higher real rates, unless accompanied by higher surpluses, will drive inflation upwards.

In conventional terms, looking at flows rather than present values, suppose a government that is $20 Trillion in debt faces interest rates that rise from 2% to 5%. Well, then it has to increase surpluses by $600 billion per year; and if it cannot do so inflation will result.

A similar story makes sense for the cyclical falls in inflation. What happened to our equation in 2008?  Surpluses fell -- deficits exploded -- and future surpluses fell even more. Debt rose sharply. Why did we see deflation? Well, real interest rates on government debt fell to unprecedentedly low levels. This really isn't even economics, it's just accounting. The equation holds, ex-post, as an identity!

To think a bit more about real rates, growth, and inflation, remember the standard relation that the real interest rate equals the subjective discount rate (how much people prefer current to future consumption) plus a constant times the per capita growth rate
\[ r = \delta + \gamma (g-n) \]
The constant \(\gamma\) is usually thought to be a bit above one.

With \(\gamma=1\) (log utility), then we have \(r-g = \delta-n\). The magic land of unbounded government debt can occur because government surpluses can grow at the population growth rate, while interest rates are determined by the individual growth rate. But population growth is tapering off, and must eventually cease, and bondholders prefer their money now. With \(\gamma \gt 1 \) ,
\[ r-g = \delta - n + (\gamma-1)(g-n) \; \; (2)\]
The new term is the per capita growth rate, which is positive, further distancing us from the land of magic.

More to the point, though, we now have before us the central determinant of long run real interest rates. Real interest rates are higher when economic growth is higher. And \(r-g\) rises when economic growth \(g\) rises.

So, going back to my equation (1), we actually had a puzzle before us. Higher real interest rates would mean lower values of the debt, and would thus be inflationary if not accompanied by austerity to pay more to bondholders. But higher real interest rates must come with higher economic growth, and higher economic growth would raise surpluses, helping the situation out. Which force wins? Well, equation (2) answers that question: With \(\gamma \gt 1\), the usual case (a 1% rise in consumption growth comes with a more than 1% rise in real interest rates), higher growth g comes with higher still interest rates r, and thus remains an inflationary force, again holding surpluses constant.

All in all then, we have the hint of a fiscal theory Phillips curve: Inflation should be procyclical. In good times, interest rates rise and the real value of government debt falls, producing more inflation. In bad times, interest rates fall and the real value of government debt rises, producing less inflation.

Central banks have been absent in all this. The natural next question is, does this provide another reinforcing channel by which central banks might raise inflation if they raise interest rates? I don't think so, but one needs more equations to really answer the question.

What matters here are very long-term real interest rates, the kind that discount expectations of surpluses -- yes, we need some surpluses! -- 20 to 30 years from now to establish bondholder's willingness to hold debt today.

In no model I have played with can central banks affect real interest rates for that long. I think a quick look out the window convinces us that central banks cannot substantially raise interest rates in a slump, with supply of global savings so strong compared to demand for global investment. Long-term interest rates really must come from supply and demand, not monetary machination. Higher real interest rates require higher marginal products of capital, and thus higher economic growth, not louder promises, more speeches, or more energetic attempts to avoid the logic of a liquidity trap.

Chari and Kehoe on Bailouts

V. V. Chari and Pat Kehoe have a very nice article on bank reform, "A Proposal to Eliminate the Distortions Caused by Bailouts," backed up by a serious academic paper.

Their bottom line proposal is a limit on debt to equity ratios, rising with size. This is, I think, a close cousin to my view that a Pigouvian tax on debt could substitute for much of our regulation.

Banks pose a classic moral hazard problem. In a financial crisis, governments are tempted to bail out bank creditors. Knowing they will do so, bankers take too much risk and people lend to too risky banks. The riskier the bank, the stronger the governments' temptation to bail it out ex-post.

Chari and Pat write with a beautifully disciplined economic perspective: Don't argue about transfers, as rhetorically and politically effective as that might be, but identify the distortion and the resulting inefficiency. Who cares about bailouts? Well, taxpayers obviously. But economists shouldn't worry primarily about this as a transfer. The economic problem is the distortion that higher tax rates impose on the economy. Second, there is a subsidy distortion that bailed out firms and creditors expand at the expense of other, more profitable activities. Third there is a debt and size distortion. Since debt is bailed out but not equity, we get more debt, and the banks who can get bailouts become inefficiently large.
For sake of argument, I think, Chari and Pat take a benign view of orderly resolution and living wills. Their point is that even this is not enough. Though functioning resolution would solve the tax distortion and subsidy distortion, the debt-size externality remains.

The extent of regulator intervention depends on the aggregate losses due to threatened bankruptcies. Individual firms do not internalize the effect of their decisions on aggregate outcomes and, therefore, on the extent of such intervention. Just as with bailouts, individual firms have incentives to become too large relative to the sustainably efficient outcome 

Their alternative: A regulatory system that

limits the debt-equity ratio of financial firms and imposes a Pigouvian tax on the size of these firms.

The paper is not specific beyond this suggestion. It's intriguing for many reasons outside the paper.

First, they limit the ratio of debt to equity, not the ratio of debt to assets. Current bank regulation is centered on the ratio of debt to assets, but then we get in to the mess of measuring risk-weighted assets, many of them at book value.  Abandoning this whole mess is a great idea.

Thinking about some of the same issues, I came to the conclusion that a simple Pigouvian tax on debt would work better than current debt-to-asset regulations. If you borrow $1 (especially short) you pay an 5 cent tax per year.

There is an interesting question then whether this tax on debt or a regulatory debt-to-equity ratio limit will work better.

Chari and Pat don't say what the optimal debt/equity ratio should be, and how that should be enforced dynamically. If up against the limit, do they want banks to sell assets ("Fire sales" and "liquidity spirals" banks will complain), to issue equity ("agency costs", banks will complain) or what?  Chari and Pat also don't say whether they want regulators to target the ratio of debt to book value of equity or to market value of equity. I like market value, further avoiding accounting shenanigans. I suspect the regulatory community will choose book value, so inure themselves from responding to market signals.

I like announcing a price rather than a quantity -- a Pigouvian tax on debt rather than a debt-equity ratio -- as it avoids the whole argument, and the just this side vs. just that side of any cliff.   My tax could rise with size, to address their size externality as well.

But they don't analyze the idea of a tax on debt rather than their ratio, so perhaps both would work as well within their model. Their ratio of debt to equity is sufficient for their ends, but perhaps not necessary.

Chari and Pat take a benign view of debt, and the functioning of resolution authority: They

start from the perspective that because debt contracts are widespread, they must be privately valuable and, in all likelihood, also valuable to society in general.

They also posit that "orderly resolution" authority will in fact swiftly impose losses on creditors, and that by using "living wills" the offending banks can be quickly broken up.

I think they make these assumptions to focus on one issue. That's good for an academic paper. But in contemplating a larger regulatory scheme, I think we should question both assumptions.

In a modern economy, liquidity need not require fixed value, and I think we could get by with a lot less debt.  That leads me to much more capital overall. They implicitly head this way,  presuming that debt is vital, but then advocating debt equity ratio regulations that will presumably mean a lot more equity.

I suspect that resolution authorities, hearing screaming on the phone from large financial institution creditors of a troubled bank,  and with "systemic" and "contagion" in mind, will swiftly bail out creditors once again.  I think that a bank too complex to go through bankruptcy, even a reformed bankruptcy code, is hopeless for the poor Treasury secretary to carve up in a weekend. So another reason for more equity is to avoid this system that will not work, as well as to patch up its remaining limitations even if it works perfectly.

Chari and Pat also step outside the model, stating that the resolution authority

is worrisome because by giving extraordinary powers to regulators, it allows them to rewrite private contracts between borrowers and creditors...[this]... can do great harm to the well-being of their citizens. Societies prosper when citizens are confident that contracts they enter will be enforced

Their closing sentence is important

We emphasize that regulation is needed in our framework not because markets on their own lead to inefficient outcomes, but because well-meaning governments that lack commitment introduce distortions and externalities that need to be corrected.

Hygienists . . . you are one of the primary educators in the practice

We all know that research shows the systemic links between oral health and the rest of the body, especially the relationship between periodontal disease, cardiovascular disease, diabetes and respiratory disease. As oral health providers, it is our responsibility to educate our patients about the significance of periodontal disease and how it will affect the rest of their body.

One of the tools you have as a hygienist is the Dentrix perio chart module, but do you know everything that it will do to help you with visual aids for educating your patients? Let me show you a few of my favorite things you can do with your perio chart.

1. Use the Graphic Chart to show your patient what a 9mm pocket looks like or where there is a lot of bleeding. You can enlarge a specific quadrant or arch to show specific areas in more detail by clicking on the + in the corners and center of the graphic chart. You can also click on the Show Options button to include the data measurements.
   
2. If you want to show your patient any changes in their perio chart, you can compare up to four exams at a time. I would recommend only comparing two exams at a time because then it will show you a colored arrow if the pocket depth got better or worse (a green arrow means it got better and a red arrow means it got worse).
   
3. You can print both of these two visual aids for your patient to take home.

As the hygienist, you are one of the primary educators in the practice. Use the tools you have in your software to enhance the case acceptance for perio therapy and help your patients work toward a healthy lifestyle. These diagnostic techniques are extremely important to getting your claims paid, but far more important is educating your patients about the link between other oral health and systemic diseases.

A better living will

"US rejects 'living wills' of 5 banks," from FT. WSJ puts this event in the larger story of Dodd Frank unraveling. Juicy quotes:

WSJ: “living wills,” ... are supposed to show in detail how these banking titans, in the event of failure, could be placed into bankruptcy without wrecking the financial system.

FT:...the shortcomings varied by bank but included flawed computer models; inadequate estimates of liquidity needs; questionable assumptions about the capital required to be wound up; and unacceptable judgments on when to enter banktruptcy.

FT: David Hirschmann of the US Chamber of Commerce, the biggest business lobby, said the living wills process was “broken”. “When you can’t comply no matter how much money you put into legitimately trying to comply, maybe it’s time to ask: did we get the test wrong?” he said.

WSJ: Six years after the law was passed, and eight years since the financial crisis, regulators given broad authority to remake American finance, with thousands of regulatory officials on their payroll, cannot figure out a system to allow financial giants to fail, even in theory. What are we paying these people for?

It seems like a good moment to revisit an idea buried deep in "Toward a run-free financial system."  How could we structure banks to fail transparently?

Recall, here is how banks are structured now (extremely simplified). Banks hold assets like loans, mortgages and securities. Banks get money to fund these assets by selling a tiny amount of equity, i.e. stock, and by a huge amount of borrowing, including deposits, long-term bonds, and short-term debt.

The trouble with this system is, if the value of the assets falls by more than $10 in my example, the equity is wiped out, and the bank can't pay its debts. If short-term debt holders worry about this event, they all clamor to get paid first, so a run can happen. That's not really a problem either; bankruptcy is set up exactly to handle this situation. The creditors who lent money to the bank split up the assets. Yes, they don't get their full money back, but if you lend to a bank that's leveraged like this, that's the risk you take.

The trouble is the widespread feeling that big banks are too big, too complex, too illiquid, to utterly muddy, to carve up this way. If it takes years in court, and if all the value of the assets is drained away by lawyers, you have a real problem. Furthermore, we often want the profitable parts of the bank to remain in operation while the creditors squabble about assets. (Ben Bernanke's classic paper on banking in the great depression makes this point beautifully.) The ATM machines should not go dark, the offices where people know their customers and can keep things going should stay in operation.

Hence, big banks become too big -- or too something -- to fail. In that situation, the government is mighty tempted to bail out the creditors and keep the thing limping along. Given that temptation, a lot of large, politically well connected creditors also scream that there will be ``systemic dangers'' if they don't get their cash now, adding to the bailout pressure. A "living will" is supposed to stop this chain, by allowing  bank assets to very quickly get divvied up among creditors.

But the large banks are, apparently, so large and complex that nobody can figure out a living will. That's debateable, for example Kenneth Scott and John Taylor argue bankruptcy can work.  But let's go with the idea. Is there an alternative to Bernie Sanders' bust up the banks? Here's one.

Starting from the left, suppose the bank holds all the same assets it does today. But, it issues 100% equity to finance its assets. Now, a 100% equity financed bank cannot fail. If you don't have any debt, you can't fail to pay debts. Yes, the bank can lose money and slowly go out of business. But it cannot go bankrupt. As it loses money, the value of its equity declines, until shareholders get mad and liquidate the carcass. Nobody can run to get their money out ahead of the other person. End of bankruptcy, end of bank runs, end of financial crises.

(Technical note. Yes, that's a bit overstated. A bank can potentially invest in derivatives and other securities where it can lose more than all of the investment. The amount of monitoring needed to make sure this doesn't happen is trivial next to the Basel sort of thing required to make sure a bank never loses more than a few percent of its value.)

OK, gulp, you say. But don't people "need" to have bank accounts? Isn't "transformation" of debt into loans the crucial feature of the financial system? Don't equity holders "require" high risk, high-return stock? No, argues the "run-free financial system" essay. But let's not go there. Let's just restructure things so that the bank can hold exactly the same assets it has today, and its investors can hold exactly the same assets they hold today.

So, moving to the right in my little picture, suppose bank stock is held in a mutual fund, exchange traded fund, or a special-purpose "bank." Bank stock is the only asset these companies hold, and that stock is also traded on exchanges. These banks fund themselves by the same mix of debt, equity, deposits, and heck even overnight wholesale debt, commercial paper, and so forth.

Now, if the value of the bank stock falls, these holding companies fail, just as my original bank failed. But there is a huge difference. You can resolve the holding company in a morning and still make it to play golf in the afternoon.  The only asset is common stock, commonly traded! There are no derivatives positions to unwind, no strange positions in offshore investment trusts, or whatever.  The "living will" simply specifies how much common equity each debtholder gets in the event of bankruptcy. There is never any need to break up, liquidate, assess, or transfer bits and pieces of the big bank.

Furthermore, there is no more obscurity over the value of  the holding company assets. We see the value of bank assets, marked to market, on a millisecond basis.

The holding companies can provide all the retail deposit services banks now provide. In fact, they could contract out to the banks to provide those on a fee basis, so the customer might not even need to know.

In addition, any sane holding company would hold the stock of several banks, diversifying the risk, and thus reducing the chances of ever needing to be wound up. Come to think of it, any sane holding company would also diversify out of banking, but now we're back to my larger vision of equity-financed banking and sensible small changes in financial structure to achieve it.

In the meantime, there you have it. 100% equity financed banks can still give bank creditors exactly the same assets they hold today, and allow failures of those debts to be resolved in a morning.

MetLife

What does "systemically important" mean? How can an institution, per se, be "systemically important?"  The WSJ coverage of Judge Rosemary Collyer’s decision rescinding MetLife’s designation as a "systemically important financial institution:" gives an interesting clue to how our regulators' thinking is evolving on this issue:

The [Financial Stability Oversight] council argued — bromide alert — that “contagion can result when relatively modest direct, individual losses cause financial institutions with widely dispersed exposures to actively manage their balance sheets in a way that destabilizes markets.”

It's not a bromide. It is a revealing capsule of how the FSOC headed by Treasury thinks about this issue.


"Actively manage balance sheets" is a fancy word for "sell assets." So there you have it. "Systemically important" now just means that an institution might sell assets, because selling assets might lower asset prices. "Contagion" and "systemically important" are no longer about runs; you see one bank in trouble and go take your money out of a different one. "Contagion" and "systemically important"  is no longer the (false, but plausible) domino theory, that if I default and owe you money, you default.

Policy is no longer just about stopping runs. Policy is not just about stopping any large bank from failing, or ever just losing money. Policy is about  stopping asset prices from falling, and stopping even the small marginal additional fall in prices that might accompany one  large institution's sales.  (Except that leverage and capital ratios now force institutions to sell even if they don't want to, a delicious case of contradictory regulatory commands.)

Owen Lamont's classic characterizatiion of policy-maker's attitude toward selling short, now applies to selling at all.

 Policymakers and the general public seem to have an instinctive reaction that short selling is morally wrong. Short selling has been characterized as inhuman, un-American, and against God

The journal nails the basic problem

For eight years, federal regulators have failed to define precisely the “systemic risks” they claim they can identify across the financial landscape.

But no definition makes it easy to endlessly expand the word's meaning.

Find patients with missing email addresses

In our age of technology, more and more people are tethered to their mobile phones, tablets and laptops 24/7. I am not only a practice management coach and trainer, but I am also a dental patient. Like an estimated 88% of smartphone owners*, if you want to contact me and confirm my appointment, the preferred method of contact is email or text message. Many times, the practice is calling patients to confirm their appointments from a back office phone line and the patient might not recognize the phone number … so the call goes to voicemail. In our busy lives, we might not check our voicemail until that evening or a couple days later. By then, it is more than likely after office hours or too late to call back.

If you are using a third-party software for email and/or text messaging, you need to make sure that you are reaching out to as many patients as possible. If you have been spotty on asking for email addresses, you can search your Dentrix software and find patients who have a missing email address. This will help you grow your email list and connect with patients in a more efficient and effective way. You will save time and your patients will appreciate it.

• ·        The first way you can search for patients without an email address is with the Dentrix letter merge feature and generate a list of patients. Go to the Office Manager > Letters & Custom Lists > highlight the Patient Report by Filters > Edit. In the lower left corner, there is a dropdown menu for email. Select only without (see the image below). Check mark patients, but I would not filter it with any other options because then you might skip some people. Click Close and click on the button for Open in List Manager. This will give you a list of patient names who do not have email addresses.

• ·        The second way you can search for patients without an email address is on a daily basis using the Daily Huddle Report. Go to the Office Manager > Analysis > Daily Huddle Report > (see image below). Click on the Selected Patient List > check mark the patients with no email. This will generate a page on the Daily Huddle that will give you a list of patients coming in today. If there is an “x” next to the no email column, then you can ask those patients for their email address.

Communicating with patients using today’s technology and in a way that is more convenient for your patients will increase your confirmations and help increase your patient retention. Do you want to learn more about Patient Retention? CLICK HERE

NBER AP

On Friday I attended the NBER Asset Pricing meeting (program here) in Chicago, organized by Adrien Verdelhan and Debby Lucas. The papers were unusually interesting, even by the high standards of this meeting. Alas the NBER doesn't post slides so I don't have great visuals to show you.


Lars Hansen started with the latest in the Hansen-Sargent ambiguity / robustness work,Sets of Models and Prices of Uncertainty. Stavros Panageas gave a beautiful discussion,  complete with power point animations. He characterized the paper as a major advance, for reducing the range of models over which an ambiguous agent looks for the worst case scenario, and for making that range state-dependent.

In the application, the agent worries that the mean growth rate of consumption and the AR(1) coefficient might be wrong; a more persistent consumption growth process is hurtful, and that pain is more in bad times.

I haven't followed this work closely enough. I still wonder what the testable implcations are -- how different is the asset pricing model from one in which the true consumption growth process is just a bit different from our estimate, in the worst possible way?

Still, it's nice to see a Nobel Prize winner leading off a conference, and with easily the most technical paper at that conference, with another one (Rob Engle) in the audience. That tells you something about the seriousness of this group. Also, this is serious behavioral finance by any metric -- a disciplined model of probability misperceptions, which is nice to see.

Robert Novy-Marx presented  Testing Strategies Based on Multiple Signals, discussed by Moto Yogo. We're all familiar with the phenomenon that if you try 10 characteristics and pick the best few to forecast returns, t statistics are biased and performance falls out of sample.

Robert pointed out that if you put those best 3 in a portfolio, they diversify each other, reducing the in-sample variance of the portfolio, and boosting Sharpe ratios and t-statistics even further.

Many ``smart beta'' funds are doing this, so the fall-off in performance from backtest to real money is relevant beyond academia.

The extent of this bias is impressive. Here is the distribution of t statistics that results when you pick the best three of 20 completely useless signals, and put them in a portfolio. Critical values of 4 and 5 show up routinely in Robert's calculations.

Laura Veldkamp presented her work with Nina Boyarchenko, David Lucca, and Laura Veldkamp,  Taking Orders and Taking Notes: Dealer Information Sharing in Financial Markets. Discussed ably (of course) by Darrell Duffie. Is it a problem that the dealers who are the prime bidders at treasury auctions have been caught talking to each other ahead of the auction?  Surprisingly, no: The Treasury can come out ahead when dealers share information with each other, and investors can potentially come out ahead too.

This warms my contrarian economist heart. We know so little about how markets work, and regulators are so quick to jump on supposedly bad behavor, it's lovely to see a clear and convincing model, that explains the kind of second-order and equilibrium effects that economists are good at.

Brian Weller presented Measuring Tail Risks at High Frequency, discussed nicely by Mike Chernov. Brian's basic idea is to run cross-sectional regressions of bid/ask spreads, normalized by volume and depth, on the cross-section of factor betas. Since spreads are larger when dealers are more worried about big jumps, this produces a measure of time-varying probability x size of such jumps. The measure correlates well with the VIX.

Michael Bauer presented his paper with Jim Hamilton Robust Bond Risk Premia discussed very nicely by Greg Duffee. (My discussion of a previous presentation). This paper is really about whether macro variables help to forecast bond returns. We're used to "Stambaugh bias:'' if you forecast returns with a persistent regressor, and the innovation in the regressor is strongly negatively correlated with the innovation in the return, then the near-unit-root downward bias in the regressor autocorrelation seeps over into upward bias of return predictability. But macro variables forecasting bond returns have innovations nearly uncorrelated with the returns, so that's not much of a problem. Michael and Jim show another problem: with overlappping returns, t statistics can be biased down too.

This led to a pleasant reassessment of bond return forecasts. Some points that came up: econometrics aside, many return forecasters don't do well out of sample. Many of the issues are specification issues orthogonal to this econometric point. For example, evaluating the huge forecastability of bond returns from a combination of level and inflation documented by Anna Cieslak and Pavol Povala, where the forecasters look a lot like a trend, is really about specification and interpretation, not econometrics. I held out the view that the important part of my paper with Monika Piazzesi is the single-factor structure of expected returns, not whether small principal components help to forecast returns. We had a pleasant interchange on whether it's a good or terrible idea to run one-year horizon forecasting regressions. I like them, because they attenuate measurement error. Raising a weekly autoregression to the 52nd power yields junk. Greg likes them, and gave a stirring reminder of Bob Hodrick's point that you can include lags of the forecasting variables instead.

Nick Roussanov presented his paper with Erik Gilje and Robert Ready, Fracking, Drilling, and Asset Pricing: Estimating the Economic Benefits of the Shale Revolution with Wei Xiong discussing. They track the reaction of stock prices to the shale oil boom. In particular, they showed that stocks which rose on a huge shale announcement subsequently rose even more as more good shale news came in. Until, as Wei pointed out, prices collapsed.

Nick also used stock market value to try to get at an estimate of the economics benefits of fracking. It's a worthy effort, but let's remember the difficulties. In a competitive no-adjustment cost world, profits are zero and there are no abnormal stock returns. Stock capitalization may rise, as firms issue stock to invest. But that measures the value of capital invested, not the consumer surplus of shale. Still, the general idea of mixing asset pricing, energy economics, and making economic measurements from stock prices is intriguing.

Jonathan Sokobin, Chief Economist, FINRA presented "An Overview of FINRA Data" which I alas had to miss. I'm delighted anyone from the government wants us to use their data!

The AP meeting has a nice tradition. Usually the most boring part of a conference is the author's response to discussant. The AP meetings do away with this -- or rather, the author can respond if someone in the audience raises his or her hand and says "I'd like to hear your response to x." That actually happened! But by and large the AP meetings preserve time and a tradition of very active participation and discussion, and this one was no different.

Next Steps for FTPL

Last Friday April 1, Eric Leeper Tom Coleman and I organized a conference at the Becker-Friedman Institute,  "Next Steps for the Fiscal Theory of the Price Level." Follow the link for the whole agenda, slides, and papers.

The theoretical controversies are behind us. But how do we use the fiscal theory, to understand historical episodes, data, policy, and policy regimes? The idea of the conference was to get together and help each other to map out this the agenda. The day started with history, moved on to monetary policy, and then to international issues.

A common theme was various forms of price-related fiscal rules, fiscal analogues to the Taylor rule of monetary policy. In a simple form, suppose primary surpluses rise with the price level, as
\[ b_t = \sum_{j=0}^{\infty} \beta^j \left( s_{0,t+j} + s_1 (P_{t+j} - P^\ast) \right) \]
where \(b_t\) is the real value of debt, \(s_{0,t}\) is a sequence of primary surpluses budgeted to pay off that debt, \(P^\ast\) is a price-level target and \(P_t\) is the price level. \(b_t\) can be real or nominal debt \( b_{t}= B_{t-1}/P_t\), but I write it as real debt to emphasize the point: This equation too can determine price levels \(P_t\). If inflation rises, the government raises taxes or cuts spending to soak up extra money. If inflation declines, the government does the opposite, putting extra money and debt in the economy but in a way that does not trigger higher future surpluses, so it does push up prices.

(Note: this post has embedded figures and mathjax equations. If the last paragraph is garbled or you don't see graphs below, go here.)

That idea surfaced in many of the papers.


The morning had several papers studying the gold standard and related historical arrangements. To a fiscal theorist the gold standard is really a fiscal commitment. No gold standard has ever backed its note issue 100%; and none has even dreamed of backing its nominal government debt 100%. If a government had that much gold, there would be no point to borrowing.

So a gold standard is a  commitment to raise taxes, or to borrow against credible future taxes, to get enough gold should it ever be needed. The gold standard says, we commit to pay off this debt at one, and only one, price level. If inflation gets big, people will start to want to exchange money for gold, and we'll raise taxes. If inflation gets too low, people wills tart to exchange gold for money, and we'll print it up as needed. Usually, in the fiscal theory,
\[ \frac{B_{t-1}}{P_t} = E_t \sum_{j=0}^{\infty} \beta^j s_{t+j}\]
the expectation of future surpluses is a bit nebulous, so inflation might wander around a lot like stock prices. The gold standard is a way to commit to just the right path of surpluses that stabilize the price level.

A summary, with apologies in advance to authors whose points I missed or misunderstood:

Part I: History

George Hall presented his work with Tom Sargent on the history of US debt limits, together with a fantastic new data set on US debt that will be very useful going forward.

Price of a Chariot Horse: 100,000 Denarii

François Velde and Christophe Chalmley took us on a lighting tour of monetary arrangements across history, prompting a thoughtful discussion on just where Fiscal theory starts to matter and where it really is not relevant. (François easily gets the prize for the best set of slides. Picking just one was hard.)

Michael Bordo and Arunima Sinha presented an analysis of suspensions of convertibility: Governments temporarily abandon the gold standard during war, then go back at parity afterward. Maybe. By going back afterward, people are willing to hold a lot of unbacked debt and currency during the war. But sometimes the fiscal resources to go back afterward are tough to get, the benefits of establishing credibility so you can borrow in the next war seem further off. When people are unsure whether the country will go back, the wartime inflation is worse, and the cost of going back on parity are heavier. They analyze France vs. UK after WWI.

Martin Kleim took us on a tour of a big inflation in a previous European currency union, the Holy Roman Empire in the early 1600s. Europe has had currency union without fiscal union for a long time, under various metallic standards and coinages.  In this case small states, under fiscal pressure from the 30 years' war, started to debase small coins, leading to a large inflation. It ended with an agreement to go back to parity, with the states absorbing the losses. (In my equation, they needed a lot of surpluses to match \(P\) with \(P^\ast\)). We had an interesting discussion on just where those funds came from. Disinflation is always and everywhere a fiscal reform.

Margaret Jacobson presented her work with Eric Leeper and Bruce Preston on the end of the gold standard in the US in the 1930s. (Eric modestly stated his contribution to the paper as finding the matlab color code for gold, as shown in the graph.)  Margaret and Eric interpret the fiscal statements of the Roosevelt Administration to say that they would run unbacked deficits until the price level returned to its previous level, the \(P^\ast\) in my above equation.  Much discussion followed on how governments today, if they really want inflation, could achieve something similar.

 Part II Monetary Policy 

Chris Sims took on that issue directly. If you want inflation, just running big deficits might not help. Hundreds of years in which governments built up hard-won reputations that when they borrow money, they pay it off, are hard to upend immediately. Even if you want to break that expectation -- all our governments have mixed promises of stimulus now with deficit reduction later.  A devaluation would help, but we don't have a gold standard against which to devalue, and not everyone can devalue relative to each other's currency.

Chris' bottom line is a lot like Margaret and Eric's, and my fiscal Taylor rule,

Coordinating fiscal and monetary policy so that both are explicitly contingent on reaching an inflation target — not only interest rates low, but no tax increases or spending cuts until inflation rises. 

But,

• This might work because it would represent such a shift in political economy that people would rethink their inflation expectations.

Chris led a long discussion including thoughts on rational expectations -- it's a stretch to impose rational expectations on policies that have never been tried before (though our history lesson reminded us just how few genuinely novel policies there are!)

Steve Williamson followed with a thoughtful model full of surprising results. The stock of money does not matter, but fed transfers to the treasury do. (I hope I got that right!)

My presentation (slides also  here  on my webpage) took on the "agenda" question. The basic fiscal equation is
\[\frac{B_{t-1}}{P_t} = E_t \sum M_{t,t+j} s_{t+j} \]
For the project of matching history, data, analyzing policy and finding better regimes, I opined we have spent too much time on the \(s\) fiscal part, and not nearly enough time on the \(M\) discount rate part, or the \(B\) part, which I map to monetary policy.

I argued that in order to understand the cyclical variation of inflation -- in recessions inflation declines while \(B\) is rising and \(s\) is declining -- we need to focus on discount rate variation. More generally, changes in the value of government debt due to interest rate variation are plausibly much bigger than changes in expected surpluses. As interest rates rise, government debt will be worth a lot less, an additionan inflationary pressure that is often overlooked.

Then I presented short versions of recent papers analyzing monetary policy in the fiscal theory of the price level. Interest rate targets with no change in surpluses can determine expected inflation, but the neo-Fisherian conundrum remains.

Harald Uhlig presented a skeptical view, provoking much discussion.  Some main points: large debt and deficits are not associated with inflation, and M2 demand is stable.

I found Harald's critique quite useful. Even if you don't agree with something, knowing that this is how a really sharp and well informed macroeconomist perceives the issues is a vital lesson. I answered somewhat impertinently that we addressed these issues 15 years ago: High debt comes with large expected surpluses, just as in financing a war, because governments want to borrow without creating inflation. The stability of M2 velocity does not isolate cause and effect. The chocolate/GDP ratio is stable too, but eating more chocolate will not increase GDP.

But Harald knows this, and his overall point resonates: You guys need to find something like MV=PY that easily organizes historical events. The obvious graph doesn't work. Irving Fisher came up with MV=PY, but it took Friedman and Schwartz using it to make the idea come alive. That is the purpose of the whole conference.

Francesco Bianchi presented his work with Leonardo Melosi on the Great Recession. New Keynesian models typically predict huge deflation at the zero bound. Why didn't this happen? They specify a model with shifting fiscal vs money dominant regimes. The standard model specifies that once we leave the zero bound we go right back to a money-dominant, Taylor-rule regime with passive fiscal policy. However, if there is a chance of going back to a fiscal-dominant regime for a while, that changes expectations of inflation at the end of the zero bound. Even small changes in those expectations have big effects on inflation during the zero bound (Shameless plug for the New Keynesian Liquidity Trap which explains this point very simply.) So, as you see in the graph above, the "benchmark" model which includes a probability of reverting to a fiscal regime after the zero bound, produces the mild recession and disinflation we have seen, compared to the standard model prediction of a huge depression.

Fiscal policy is political of course. Campbell Leith presented, among other things,  an intriguing tour of how political scientists think about political determinants of debt and deficits. My snarky quip, we learned with great precision that political scientists don't know a heck of a lot more than we do! But if so, that is also wisdom.

Part III International

red line regime switching probability of 30%, blue line 0 % 

Alexander Kriwoluzky presented thoughts on a fiscal theory of exchange rates, applying it to the US vs. Germany, the abandonment of the gold standard and switch to floating rates in the early 1970s. An exchange rate peg means that Germany must import US fiscal policy as well, importing the deficits that support more inflation. Germany didn't want to do that.  People knew that, so a shift to floating rates was in the air. Expectations of that shift can explain the interest differential and apparent failure of uncovered interest parity.

Last but certainly not least, Bartosz Maćkowiak presented a thoughtful analysis of "Monetary-Fiscal Interactions and the Euro Area’s Malaise" joint work with Marek Jarosińsky.

Echoing the fiscal Taylor rule idea running through so many talks, they propose a fiscal rule
\[ S_{n,t} = \Psi_n + \Psi_B \left( B_{n,t-1} - \sum_n \theta_n B_{n,t-1} \right) + \psi_n (Y_{n,t}-Y_n) \]
In words, each country's surplus must react to that country's debt \(B_n\), but total EU surpluses do not react to total EU debt. In this way, the EU is "Ricardian" or "fiscal passive" for each country, but it is "non-Ricardian" or "fiscal active" for the EU as a whole. In their simulations, this fiscal commitment has the same beneficial effects running through Leeper and Jabcobson, Bianchi and Melosi, Sims, and others -- but maintaining the idea that individual countries pay their debts.

A big thanks to the Harris School and the Becker-Friedman Institute who sponsored the conference.

Recare is the lifeblood of your practice

If you are a general practice or pediatric dental practice, your recare system is the lifeblood of your practice. Your doctor’s schedule feeds off the hygiene patients so it is critical that you have a seamless system. But are your hygiene systems working as well as you think they are? You may have patients falling through the cracks or not receiving the reminders that you think they are.

The most important component of your recare system is the setup and making sure your team understands the details. I want to take some time today to walk you through proper setup, checking your individual patients continuing care, and which report to manage.

First, the setup is key. I wrote a blog post on May 23, 2012, called “KISS your Continuing Care Types,” but obviously not everyone read it so I am going to take some of those tips and re-apply them today. Many offices, understandably, try and create a system for 3-month Perio, 4-month Prophy, etc., by setting up new Continuing Care types but trust me . . . IT DOESN’T WORK! Remember that you can only attach one Continuing Care type to the procedure code. To

understand what I am talking about, go to the Office Manager > Maintenance > Practice Setup > Procedure Code Setup, then highlight the D1110 and click edit. You will notice in the middle of the window there is a >> Auto Continuing Care where you can attach one Continuing Care Type to this code. This means you cannot link up a 4-month Prophy and 6-month Prophy to the same code.

Your options are Prophy and Perio or Recare. You can link the Prophy to the D1110 and the D1120 and the Perio to the D4910, or link the Recare to all three.

After you have this setup corrected, when you schedule your patient for a cleaning, it will link up to the appointment correctly. When you set complete, it will update your patient’s due date.

But what if your patient is a 3-month Perio or 4-month Prophy? How do you get it up update the due date correctly? You can update the patient’s frequency on his or her Family File in the Continuing Care window. Once you change the patient’s recare frequency, then your reports will be accurate. When you schedule the patient for his or her next visit, the system will know when he or she is due.

After you get this setup fixed and the patient’s frequency updated on the Family File, then you can feel confident that your Continuing Care Report is accurate. If you are using the Dentrix eCentral communication manager, you will know that your patients are receiving reminders when they are due. For a full article on the Continuing Care report, CLICK HERE.
