Last Update: October 28, 2008

I am also posting my book's future section of the financial system, while I am writing it (thus, it is not yet complete). Nevertheless, if you have the background of a first course in finance, it should help you to understand what these financial innovations were, and how they came about.

A Personal FAQ on the Financial Crisis of 2008

Background

Who Wrote This FAQ?
Ivo Welch, a reasonably well-known professor of financial economics, currently at Brown University (previously at UCLA and Yale). I am also the author of an introductory corporate finance textbook.
When Was This Written?
The first draft was written on October 6, 2008. Since then, I have been making small changes.
Who is FAQ Written For?
Primarily for non-economists, although many economists should find it interesting reading, too.
Can I cite or link to this FAQ?
Yes. Cites are not necessary, but links to this page are definitely appreciated.
Are you a Republican or Democrat?
Neither. I am an economist. Of course, I have opinions. Some of my opinions are closer to those of one party, some to the other. Overall, I tend to be somewhat libertarian, though—live and let live. However, I do believe that certain basic human rights trump economic rights, even when it harms efficiency.
Who do you support? Obama or McCain?
I do lean a little toward towards Obama, the candidate. (I used to lean towards the Reagan wing of the Republican party, which has almost vanished, unfortunately; I hate the Bush administration, which has transformed the party of smaller government and personal liberty into a party of southern-fried moralism [quoting the Economist].)
Will Obama or McCain be better for the economy?
Most importantly, we must recognize that the power of the president is limited, as is his influence on the economy. Economic systems are highly dynamic (and global competition allows firms and many high-skill employees to move if we do the wrong thing). Domestic constraints, arising out of both economic reality and politics (Congress), will force the hand of the next president. Both economic advisors, Austan Goolsbee and Douglas Holtz-Eakin, are pretty darn good, too—especially when they are not on the campaign trail.
How "scientific" are your opinions in this FAQ?
I try to base my opinions here on good economics. I also try to indicate which of my opinions are more controversial, and where intelligent people may disagree.
Do you take intellectual credit for the information in this FAQ?
No. The statements and suggestions here derive from many sources and many economists (a sampling: Anil Kashyap, Luigi Zingales, Jeremy Stein, Ross Levine, etc.). I believe most of us economists are now less concerned about taking intellectual credit than they are about making useful suggestions.
How do economists' views differ on the crisis?
Economists' views on the subject differ primarily along two dimensions:
  1. Some economists focus more on the short-term problems (and fixes), and other economists focus more on the long-term problems (and fixes). Unfortunately, short-term fixes often have bad long-term consequences.
  2. Economists differ in terms of assessing the costs vs. the benefits of government regulations, both specific regulations in the financial sector and regulations in the overall economy.
(More on both points below.) All economists agree that short-term and long-term fixes can be in conflict, that there are both costs and benefits to financial regulation, and that the stakes are potentially very large.
If you had to characterize in brief your own opinions on the crisis, what are they?
My own opinions are:
  1. We should do whatever it takes to fix the short-term problems. Then we should attack the long-term problems. This may require dismantling many of the short-term fixes.
  2. We have no choice but to try to balance the costs and benefits of regulation. We have to try to come up with effective and affordable regulation.
Are these descriptions, opinions, and suggestions the only ones? Are they encyclopedic?
No. There have been many good opinions voiced and suggestions made elsewhere. The current crisis is the result of many complex forces, so this should not be a surprise. I am also not a reporter, so I am better at general descriptions than I am at being up-to-date with all the minute details.
If you had to characterize this FAQ in brief, how does it differ from others?
It decomposes the causes of the credit crisis into multiple layers. It is more prescriptive and informed on the long-term fixes we need than it is on the short-term fixes.

The Financial Value Background

Our Assets

What are our assets, liabilities, and wealth?
I am not a macroeconomist, so I will just report what the Federal Reserve stated in its balance sheets, as of the end of 2007 (before the crisis began):
Households Corporations Financials Total
(NOT NET!)
Tangible Assets
(incl Real Estate)
$26.7 trillion $27.4 trillion $7.9 trillion $62 trillion
...Real Estate $22.5 trillion $8.9 trillion $7.3 trillion $39 trillion
Financial Assets $45.3 trillion $12.9 trillion $3.1 trillion $61 trillion
All Assets $72.1 trillion $27.4 trillion $11.0 trillion $110 trillion
Home Mortgages $13.8 trillion NA NA $14 trillion
Commercial Mortgages $0.2 trillion $1 trillion $2.5 trillion $4 trillion
All Liabilities $14.4 trillion $11.3 trillion $5.0 trillion 31 trillion
Net Worth $57.7 trillion $16.1 trillion $6.0 trillion N/A
Owner's equity as percentage
of household real estate
48%
Debt to Value 47% 59%
Real estate was our biggest asset counted in the Fed statistics. About $18 trillion was in mortgages on $39 trillion of real estate. However, our most valuable asset, which is our human capital, is not in the table. The assets of our federal, state, and local governments are not in the table, either. (I do not know how intellectual property is treated.) PS: If you know of simpler, better, and total statistics, especially net, please send me an email.
How much have house prices moved?
Nationwide, the Case-Shiller house price values index (called CSXR, each July) was:
July 1987 68
July 1988 75
July 1989 82
July 1990 82
July 1991 79
July 1992 78
July 1993 77
July 1994 77
July 1995 77
July 1996 78
July 1997 81
July 1998 88
July 1999 96
July 2000 109
July 2001 121
July 2002 135
July 2003 152
July 2004 183
July 2005 212
July 2006 226
July 2007 216
July 2008 176
Next Year:
July 2009 ??140??
Note: As of August 2008, the index seems to continue declining at a rate of about 1.1% per month (about 15% per year).
Has the economic crisis made us collectively poorer?
Yes. We do not yet know by how much real estate will decline, but 30% seems like a reasonable guestimate. This would represent about $13 trillion worth, which is a good 15-20% of our (non-human capital) net worth. Most of these losses will be borne by the owners of the real estate. A small part of these losses will be borne by banks that have lent to real estate owners who will default on their mortgages and walk away from their houses. Update as of late October 2008: The stark decline in the stock market (anticipating losses in the real economy) and many other assets has cost us more than the real-estate crash has. (In late 2008, the Dow Jones was about where it was 10 years earlier (on 2/27/1998, it stood at 8,545.) Estimates of the losses now at the end of 2008 are about $3 trillion.
The houses are still here, so how can we be poorer?
It's like finding out that you built a house in a place where you can no longer find work at the same pay rate as before or elsewhere. The house is still there, but it is less valuable to you. As an economy, we have deployed our wealth in a way that with 20/20 hindsight was not the best we could have done.

Subprime

How much new borrowing did we accumulate from 2001 to 2007?
According to Fed statistics, households took on about $5.6 trillion in debt during these years (though some unknown amount has surely been paid off already). This was about half of the total private borrowing in the economy. Most of the new household debt was in mortgages.

It is the debt accumulated from 2001 to 2007 that may be most vulnerable to default due to the rise and then collapse of real estate values. Holding everything else constant, the closer to 2006 a mortgage loan was taken out, the more risky it is now.

How much in outstanding mortgages is subprime and alt-a (the next-worst category)?
From the NY Fed (thanks to Rick Sias for pointing me there), from August 2008, rounded:
Subprime Alt-A
Outstanding $537b $726b
Originated before 2004 23% 15%
Originated in 2005 26% 28%
Originated in 2006 38% 36%
Originated in 2007 15% 21%
Loan-To-Value at origination 85% 81%
High Credit Score (>660) 21% 80%
Percent w/ Current Payments 57% 81%
in Foreclosure 10% 6%
As of Nov 2007, according to the Center for Responsible Lending report, about 7.2 million families held a subprime mortgages, of which 15% were in default.

Gary Gorton has written a more detailed analysis of subprime mortgages in The Subprime Panic.

How much could the (subprime) mortgages cost our financial system?
The following are guestimates: This gives me the following table:
Year to-2004 2005 2006 2007 2008
Real Estate Value Index 183 212 226 216 176
Relative Value at 140 76% 66% 62% 65% 80%
"Underwater" at LTV=85% 9% 19% 23% 18% 5%
Originated Subprime $124b $140b $204b $81b
Originated Alt-A $109b $203b $261b $152b
Total Mortgages $232b $343b $465b $233b
Total Loss $21b $65b $107b $42b

The total loss attributable to subprime and Alt-A should thus be around $235 billion. Add a fudge factor and make it $300 billion.. Add another $100 billion for another 10% drop in real estate values (to 125), if you wish. I believe the loss will be well below $500 million when all is said is done.

Please note that I have broken many rules on how one properly aggregates probabilities and random variables [with dispersion] in estimating this loss number. I have also ignored:

Update, Oct 31, 2008: First American CoreLogic reports that 7.63 million properties (18%) were underwater, possibly followed by another 2.1 million soon. (2/3 of all properties have mortgages.) In Nevada, 48% of owners have negative equity; in New York, only 4.4%. Unfortunately, they do not tell us what the average dollar amount or LTV is by which these underwater mortgages are underwater. From another source, the average U.S. house price is about $250,000. The average mortgage is thus probably around $200,000. If the average underwater amount is 10% ($20,000), then we are talking $140 billion. This is again the same order of magnitude for the mortgage losses as my estimate above.

Given that mortgage losses by banks are likely to be less than 1% of our economy's assets, it cannot be that they are principally responsible for our current economic state. Moreover, one would think that the potential loss should already be covered by the financial bailout passed by Congress. The fact that it has not stopped the mortgage crisis is an indication for how much loss in trust there is, how messy and complex the structure of our mortgage-backed securities are, and that the crisis is now much bigger.

Is it still just a subprime crisis?
No. The crisis has long since spread from real estate, to mortgages, to banks, to the financial markets, to the broader economy.

Banks

What are bad bank assets really worth?
Thinking in terms of a simple value is a mistake that even (or especially) many economists, trained in perfect-market thinking, commit: They work with asset value, as if it were a unique number. However, it is easy to prove that this is not the case (value is not unique) when markets are imperfect.

Let me explain: IBM shares have a unique value. They are traded in in a perfect market, with many buyers and many sellers. The market for IBM shares is liquid. Contrast this close-to-perfect market for IBM shares with the market in real estate. Even in a normal market, only a fraction of the population is potentially ready to purchase a new house. A small change in the number of people or houses on the market can make a big difference in terms of the sale price or the time-to-sale. The housing market is rarely liquid, and certainly not at the moment. Now, if the owner needs the cash tonight, there are not many buyers that can buy so quickly, even if the price were a little lower (than if the seller can wait). Thus, the value of the house depends on who the owner is (how quickly she needs cash), and how liquid the market is (how many potential buyers there are, especially in the short-term). Let me call the fact that the house has no unique value an "indeterminacy."

Right now, the value of so-called "bad bank assets" has itself become a function of the liquidity crisis. Because the market for bank assets (loans) is no longer liquid, many banks have been trying to hoard liquidity and sell their assets (loans) very quickly. In turn, because many banks have been trying to hoard liquidity, the market for these assets is no longer liquid. It is a direct consequence of illiquidity that the market for bank loans is no longer perfect and thus that the value of the bank assets is no longer unique. (Economists can disagree about how bad the indeterminacy is in the current liquidity crisis—how far from a perfect market the current situation is.)

On the positive side, I expect the Treasury and other investors who do not fear a run on themselves (such as foreign sovereign wealth funds) to make money from buying assets from banks (unless the Treasury pays ridiculously high prices).


What Caused the Crisis?

What is all this Fannie Mae and CDO mumbo-jumbo in the press? What is this financial market that everyone is talking about?
I am also posting my book's future section of the financial system, while I am writing it (thus, it is not yet complete). Nevertheless, if you have the background of a first course in finance, it should help you to understand what these financial innovations were, and how they came about.
Was the mortgage crisis foreseeable?
Yes and no. It was foreseeable in the sense that real estate and mortgage securities would decline in value sooner or later. The housing downturn was forecast as early as 2006, at a time when credit spreads were still at historic lows. It was not forecastable as to when the crisis would occur.

Remarkably, the management groups of our banks were so bad that they did not take the appropriate steps to insure themselves. (This was a sign of poor governance. Gambling on continuation of the "easy money" lending situation, even in the face of information that it was becoming less and less likely, was more in their self-interest than cutting short-term profitability and bonuses. For more, see below.)

What did you mean by multiple layers of causes above?
Why does a car move? Is it because gasoline combusts, because it has an engine and wheels, or because the driver hits the acceleration pedal? The answer is, of course, all three, but in different ways (the "layers of causality" metaphor). The shallowest layer is the driver hitting the gas pedal; the middle layer is the car construction; and the deepest layer is that combusting gas creates energy.
What is the cause of the current crisis?
In this crisis, there are not only many causes, but also many layers of causes. When economic experts offer differing advice, most of it is not in conflict. Instead, different economists focus on different layers of causality. The most well-known causes of the current crisis are at the middle and shallow layers.

Situated roughly in the middle layer, there is the fall in real-estate prices. This decline in real estate values has caused many mortgages to be either in actual default or unlikely to be paid back. These mortgages are disproportionately owned, in one form or another, by financial institutions.

Shallower causes are:

Deeper causes include the following:

Corporate Governance
The U.S. corporate governance system is badly broken. There has been a lack of good corporate governance in the U.S. for decades. This is an economy-wide problem. It is just that in finance, everything happens with more gusto. (Arguably, bad corporate governance has also largely destroyed the American car industry.)

It was poor corporate governance that made it in the interest of management and employees in banks to gamble with the shareholders' money, much more than the shareholders would have wanted to gamble themselves.

Shareholders would have wanted some gambling (call it risk-taking), especially if it was smart and had positive expected returns—which it did for many years. Arguably, it was also in the shareholders' interest to gamble with the taxpayers' money. I judge that this was of much lesser importance than the misaligned CEO incentives.

It is the task of the Chairman of the Board (and the Board) to make sure that the CEO does a good job—not just in terms of current earnings, but also in terms of controlling risk, investing in long-term ventures, etc. Unfortunately, it is rare that poor CEOs are fired by their Chairmen, because in most corporations the CEO is also the Chairman. The fact is that shareholders in large, old companies have very little influence. This is not an easy problem to fix, but if we want to improve the economic system in the United States, improving our corporate governance is of paramount concern.

Tax Code
The U.S. tax code is also broken. It encourages deductible (homeowner) mortgage borrowing, especially in order to reap low-tax capital gains in the future.
Bankruptcy Code
Add the bankruptcy code to the list of broken institutions that we need to fix. It is most problematic when it comes to systemic bankruptcies (i.e., many that occur at the same time), and bankruptcies that affect banks. It takes years to untangle who owns what in large bankruptcies. The fact is that that our bankruptcy code makes it in the interest of clients of banks to withdraw their funds when they believe a bank is in trouble. This can even create a self-fulfilling prophecy.
Human Flaws
Many buyers of mortgage-related securities were not only conflicted, but also just stupid. Because they had made money in good times, many thought of themselves as being very smart and savvy. They did not properly take risk into account. With rating agencies intellectually outgunned by their Wall Street investment bankers (and financially rewarded by them for being outsmarted), it seemed to many naive buyers that they were buying safe securities, when they were not. In fact, the magic of securitization (and ratings) seemed to make the total set of all sliced-out securities much less risky and worth much more than what they were worth when they were whole. In simple terms, this essentially violated a basic law of nature. It made no sense.
Why is it useful to think of layers of causes?
Aside from more conceptual clarity, there is a direct practical advantage: Many shallow layers are probably best tackled in the short run; medium layers in the medium run; and deep layers in the long run.

Remedies For the Financial Crisis

What are the consequences of not cleaning up the banks?
If we do not clean up the banking sector, it will hamper the ability of the real economy to operate. We need banks that make smart loans in order to allocate our capital to the best use. If banks are themselves "underwater," they are too tempted to gamble and make bad loans. We cannot let this happen. (The failure to clean up banks probably cost Japan 5-10 extra years of recession in the 1990s.) There is also some evidence that Main-Street-Lending disproportionally helps people at lower income levels.
Should we allow de-facto bankrupt banks to continue to operate?
No. It sets up even worse incentives for their management to gamble by making risky loans.
Should we allow de-facto bankrupt banks to fail and disappear?
In a perfect world, yes. Someone else would acquire the assets and simply continue operating the next day. In the real world, absolutely not. Firms are valuable because they are more than the parts. Humpty-dumpty can be easily broken, but not easily put back together again. By the time this someone else appears, the value of these failed banks will have probably deteriorated so badly that they are worthless—and our economy will be worse off for it.
Is a bailout necessary?
In my opinion, yes. For the immediate future, we need to bring the financial system back into a reasonable state, in which cascading failures with catastrophic consequences for the whole economy are avoided. After this is over (and it will be over), we can then look back and try to assign guilt; and we can then look forward and see what we need to fix so that our financial and corporate governance system will emerge in a better form.
What exactly should we do to remedy the financial crisis?
Because there were multiple layers of causality, the cures need to operate on multiple layers. There is also a difference between what we should do now and what we should do in the long run.
For the short-run, what are our objectives?
The goal should ultimately be that the government should rescue banks that are underwater in the sense of making it transparent and painless for depositors and customers, but painful for existing (not future) management and owners. In FannieMae's case, FreddieMac's case, and AIG's case, our government mostly succeeded in doing this. (In Lehman's case, it failed. I would argue that this was a learning experience. We needed to learn what would happen if we did allow such a failure. At that point, even some very good economists were in favor of letting banks fail.)
What do you think of the current team running the economic rescue plan?
We have a very good Fed chairman (Ben Bernanke), who is extremely competent and working hard to do the right things. Economists' views on the Treasury secretary Paulson seem to be ambivalent. On the plus side, together with Bernanke, he is trying to reinstall confidence in financial institutions and inject liquidity into the system. Like the rest of us, Paulson is also learning as we go. We now have new and better ideas than we did at the start of this crisis. On the minus side, it is not clear that Paulson has the intent to follow the best advice. It seems as if he is still thinking of the WS crowd as the "good guys"—that it was not their fault. This seems to make him too reluctant to take away their cookies. As for most economists, we don't much care whether the Wall Street guys were at fault or will come out ahead. We are more concerned with what is done best now. (However, Monday morning quarter-backing is a lot easier than throwing the ball.)
What were/are our short run plans?
The short run should address the shallowest set of causes, which is primarily the breakdown of the financial credit sector.
What should be our short run plans?
Interestingly, the best plans proposed by my fellow economists would cost the tax payers very little. They mostly fall into two classes: forcibly increasing the capital base of our banks, and allowing for renegotiation of underwater mortgages. Specifically, The earlier plans (purchasing bad assets and investing in the banks), bad as they are, would be better if executed jointly with the forced conversion and dividend restrictions. If we relied more on the two latter remedies, we could then use the bailout money passed by Congress to guarantee the more short-term flow of capital among banks, companies, and individuals. If need be, we could purchase some common equity in these banks, too. (I think that purchasing preferred equity, rather than common equity, is not a good idea.)

(Note: none of the above were my ideas.)

What should we do in the medium run?
The medium run should address the middle layer of causes. The two basic options are to increase the value of houses, or to increase the value of bank assets (mortgages).

I have also read many other good suggestions, both in the financial and academic press. In fact, there are so many that I cannot possibly repeat them all.

Should we bail out homeowners?
To a certain extent, yes.

There is strong evidence that housing structures deteriorate quickly when homeowners walk away. We should try to stem such abandonment when it makes financial sense. Unfortunately, this is not as simple as it may seem. In a perfect market, we would just let the bank and borrower negotiate a good settlement. We do not live in a perfect market.

If the Fed were to purchase mortgages, it would not be a bad idea to renegotiate the loans to lower the interest rate and principal to the point where it would no longer be in the interest of homeowners to walk away—even if it is a wealth transfer from the tax payers to the homeowners.

What are the problems with your short-term (and medium-term) suggestions above?
Many good short-term suggestions can have bad long-term consequences. For example, many economists point out that if we rescue banks now, future banks will expect rescues, too, and behave accordingly (badly). If we bail out home-owners who have made bad purchases now, they and others will expect bail outs in the future again.

The most worrisome short-run fix to me is that we are creating even bigger financial giants, which are more stable right now, but which will be even more "too-big-to-fail" when the crisis is over. Moreover, the resulting lack of competition means that these few banks may then have enough market power to charge businesses very high interest rates, which will cost us future economic growth.

Are we bailing out those that caused the crisis? (This was so phrased by The Economist)
Not really. The crisis was principally caused by financial executives' excessive risk-taking and poor management. Most of these executives have been removed. In this sense, the government is not bailing out the most direct culprits.

Longer-Term Reform and Regulation

Long-run reforms are also best undertaken with some perspective. Thus, this is best done not right now (in October 2008), but when the immediate crisis has blown over.

With the government soon holding stocks in U.S. (financial) corporations, are we turning from our capitalist economic system toward socialism?
Wake up. We have never had a fully capitalist system. Governments have always partaken in the profits of corporations—it's called taxes. Governments have always had great influence over how corporations operate. For example, the SEC (used to) prevent executives from insider trading. FASB lays down the ground rules of what financial reports should look like. The state of Delaware (where most large corporations are incorporated) puts some restrictions on conflict-of-interest between management and shareholders. The tax code specifically incentivizes certain activities and punishes others. In sum, the fact that the U.S. government becomes a shareholder now is just a matter of degree, and not a drastic change.
Can we rely on the free market to fix this (and other economic problems)?
No. No sane economist would argue that one can rely on the free market for everything. Somalia is a state in which there is no government. The outcome is terrible.
Can we rely on the government to fix this (and other economic problems)?
No. Governments and politicians often mess up what they touch so badly that the outcome is terrible, too. (More below.) The Soviet Union was (and North Korea is) a state in which the government rules. The outcomes are always terrible.
So who can we rely on?
There are no easy answers. A functioning capitalist market can exist only in the presence of some good government regulation. Think of an analogy: It is not optimal to have no police, and it is not optimal to have a policeman on every corner. The trick—and it is not an easy one—is to find a good balance between not having too much and not having too little regulation. Regulation ought to be effective, efficient, and in the interest of the public. Obviously, good regulation is very hard to come by. It is a constant struggle. If it were easy, we would already have the right level. The fact that even unconflicted economists (unlike politicians that are beholden to voters and interest groups) are agonizing over what we should do is an indication just how difficult it is.
What should we consider when thinking about good regulation?
We should not let the sentiment of the moment drive regulations that will likely remain with us for decades to come. (It takes a long time before bad or obsolete rules are dismantled. How many traffic or stop lights have you ever seen coming down when they were no longer necessary?) We need to wait a little before we enact reforms. We need a clear and sober mind, not emotions and anecdotes of bad things that happened when we did not have regulations. Yes, strong regulations can prevent a lot of bad things—but they can also strangle our economic development through unintended consequences for decades to come:

If you need an example of bad governance, just look at the most recent one: Sarbanes-Oxley (SOX) is an example of how the Enron debacle settled us with terrible new regulations, potentially for decades. SOX is inefficient, ineffective, and expensive. From my perspective, it is depressing how momentary gut instincts and political lobbies can determine economic regulations, rather than sound economic principles and common sense.

Can good regulations avoid all financial crisis in the future?
No, probably not. The only way to avoid them is not to have a financial system. In the Stone Age, there were no financial crises. It is not in our interest to have regulations that make it impossible for future crises to occur. It is only in our interest to have regulations that reduce them.
Are you optimistic that we will pass good regulation?
No. Our political system has attention deficit disorder. If we try to regulate long-term solutions in the midst of the crisis, we will likely end up with emotion-driven, strangling regulation. If we wait and contemplate what we should do, the Wall Street lobby will likely have the ability to torpedo the process. It's a catch 22. (This is also one reason why I advocate setting up a non-political board with SEC endorsement now [see below]. Doing so may skirt these two extremes.)

Specific Recommendations for Long-Run Regulation

What should we actually do in the long run?
The long run should address the deepest layer of causes. Here are my suggestions:
Corporate Governance
  • Establish a Corporate Governance Standard Board in charge of recommending best practices, just as there is a Financial Accounting Standards Board (FASB) recommending acceptable practice (GAAP). This board will not fix all the problems of corporate governance, but experience shows that FASB has been more flexible and better in dealing with firms than the typical political regulation regime has. This board should be working in conjunction with and be chartered by the SEC. Firms that follow the "generally acceptable best corporate governance practice code" should also receive more safe harbor protections from civil law suits. (I have specific ideas of what this board should suggest [described in my corporate governance chapter in my textbook], but it is more important to have such a board than it is to follow my specific ideas.)
  • Appoint an economist as head of the SEC, not a politician or a (pure) lawyer—at least every once in a while. The SEC is no longer merely an insider trading enforcement agency, but the premier regulatory agency for U.S. corporations.
  • While we are at it, repeal SOX.

For more detail on the broken governance system and potential remedies, you might find the last chapter of my book to be interesting.

Tax Code
Change the tax code to reduce the incentives of homeowners to borrow. A homeowner with a $500,000 house, a $400,000 mortgage and thus $100,000 in equity, now receives a mortgage tax deduction of about $20,000. A homeowner with $500,000 in equity receives no tax deduction. It is not a mystery that people not only buy "too much house," but also with "too much debt."

I do not have it worked out how this should best be fixed, but one can think, for example, of alternatives such as:

  • Allow owners to depreciate their houses, possibly with only partial recapture of depreciation at the time of resale. (This system exists in Germany.)
  • Eliminate both the mortgage interest deduction and property taxes. The state structure of taxes makes this more difficult to undertake, but potentially more sensible, especially because local governments will soon be tempted (or forced) to increase property taxes.
Bankruptcy Code
The bankruptcy code is not prepared for dealing with systemic failure situations, especially in the financial sector. We cannot afford lawyers arguing for 5 years about who owns what, while every depositor is stuck in limbo (and possibly going bankrupt, even though her assets would ultimately be returned).
Human Flaws
I see no easy fixes for situations in which supposedly smart buyers are just stupid. (My personal recommendation to anyone: don't buy anything that you do not understand. If you are still tempted, ask yourself why a security was structured in a way that makes it difficult for you to understand.)

In addition,

Information
Encourage more disclosure of financial obligations of regulated banks:
  • If investors and clients know what banks are worth, they would be less antsy to work with them. Standardized disclosure makes comparison easier. In the time of the internet, we can make disclosures simpler, quicker, and more sensible.
  • We need to make sure that the interested public (and academics) can study phenomena taking place in the financial markets. Many of the related markets have become so obscure (they are "over-the-counter," which means that only the involved banks really know the transactions and prices) that no one can shine a light on them any longer, even months after the transaction.
  • We need to improve the information that the Fed has.

My specific suggestion: Every financial institution with assets of more than $50 million should have to upload its daily estimated NAV (one single number!) to a website run by the Fed, with no more than 1 week delay. (Most financial institutions should already have such an estimate. Indeed, I know for a fact that most big banks and hedge funds already compute this information every night in real-time. The upload of this data to a Fed website itself can be easily automated. The estimated regulatory cost: 5 minutes for one employee per day.) In an advanced version, banks would also report a "confidence"< in this number.

This kind of high-frequency information would allow the Fed to run models in-house to determine whether financial institutions are exposed to systemic risk—for example, if too many banks are exposed to yield curve or oil price risk, or simply how strongly it all moves together. After a 6 month delay, academic research on this data should be permitted by the Fed, though with strict publication anonymity controls. Finally, after 3-5 years, this information should be released to the public, similar to how Edgar information is released.

This simple disclosure would do a whole lot more for the system than onerous detailed regulations about what banks should do in-house. Remember: even if it worked perfectly, banks could still only work out their own risks. They are not able to detect the systemic risks that we are really most afraid of. Systemic risk detection requires systemic data. Of course, my recommendation is not a panacea—for one, it still requires on getting accurate data from the banks to the Fed. Still, it is a whole lot better than what we have today. It would also augment the Basel accords

Too-Big-To-Fail
All methods to avoid banks that are too-big-to-fail are outright distasteful (too much government meddling), but there is really no choice: we have to tackle this one. Unfortunately, history shows that governments do not do a good job when meddling in the economy. But we cannot allow a situation in which government is obliged to write unlimited checks to such firms every time that they get themselves into trouble. There are essentially two options:
  1. We can break up giant banks into smaller banks whose failure will not bring the entire system into trouble.
  2. We can attempt to supervise banks more closely. (But how do we deal with potential entrants? Do we want to make founding new banks difficult?) In any case, supervision would be a constant cat-and-mouse game—and there is more intellectual firepower on the side of the money than on the side of the government. Maybe the government could have some permanent minority representation on the board, as well as regulate the capital requirements. The capital requirements need to be smarter (not just more). We could also impose limits on how long Fannie and Freddie may hold mortgages, before they are selling them off into the market.

For many reasons, the second option is a losing proposition in the long run. The market should determine which banks survive, not government regulation. Most likely, we will need both. Hopefully, smarter people than myself will work on the too-big-to-fail issue.


Whose fault was it?

Whose fault was it?
This specific crisis was a breakdown of the system, with many parties at fault. The principal ones were:
  1. the poor corporate governance rules in the United States;
  2. executives and employees of financial services companies acting within these rules, and thereby profiting handsomely;
  3. the rating agencies, whose ratings made bundles of loans seem safer than the underlying loans;
  4. and buyers who bought assets that they did not understand.

There are also many other parties with secondary faults who contributed:

  1. the politicians and community activists that clamored for more loans to people who could ill afford them;
  2. the politicians and lobbyists who controlled the regulatory processes;
  3. the fact that those originating the loans had an interest to make any loans, even under false pretense;
  4. the naive homebuyers that wanted to get rich quick;
  5. the tax code that favors debt over equity;
  6. etc.
What roles did hedge funds play in the financial crisis? Are they villains?
Hedge funds overall did not play a large role in the crisis. In fact, on average, compared to other banks, hedge funds did very well. They did not make things worse by failing themselves.
What roles did short-sellers play in the financial crisis? Are they villains?
Short-sellers did not play a large role in the crisis. They tend to be made scapegoats, probably because they seem strange to ordinary retail investors. (The only exception was the fact that hedge funds may have sold short certain banks [e.g. Lehman] from which they were themselves withdrawing their money, thereby helping to cause the failure. However, this is the equivalent of blaming a duelist for following the rules of a duel.)
Did the banking deregulation at the turn of the century cause this?
In the late 1990s, Glass-Steagall was repealed (under the leadership of Senator Gramm, often bedeviled now for having done so; he is a convenient target). This repeal allowed investment banks and commercial banks to merge. It had very little to do with the current crisis.
Is our current economic state the fault of the current administration? Of the current or the last Congress?
Not really. Their errors were of omission, not of commission. That is, they enacted some stupid economic policies, but, as far as the credit crisis is concerned, these were mostly minor contributors in the overall scheme of things. Principally, the government could and should have done a lot of good things that they failed to do.
I hear a lot about a history of fraudulent lending practices. Was this the cause?
Fraudulent lending contributed to the crisis, but it was not a main cause. Such activities can be dealt with through the justice system (although our courts are already overburdened and understaffed). We need a better and cheaper legal system to deal with such issues.
Is financial development, e.g., investing in mortgages or mortgage securitization, a bad idea (from a social perspective)?
No. Investing too much in mortgages is a bad idea. Let's also not forget: the financial investments have served our economy well for 25 years—they have supported a lot of economic development, salaries, and tax revenues. Even given the current crisis, net-in-net, financial development was still a positive for our economy. Of course, our financial sector went way too far.
Should we punish those who profited for years from the system?
Let's be clear: most of those at fault for causing the loan disaster are walking away as very wealthy men (mostly men, few women). Yes, they would have been better off if the crisis had not happened. (Many did lose money in the final crash.) However, they made all their money through these very gambles for years. What they won in years past seems to be their's to keep.

An analogy is an airline that does not conduct any airplane maintenance. It can make more money for a long time. Ultimately, the plane may crash and people may die. The airline did not want the accident to happen, but may have profited handsomely by taking the chance that it might happen. (For economists, I consider bank practicies to have been the equivalent of writing out-of-the-money options and/or selling liquidity—profitable most of the time, catastrophic every once in a while.)

Shareholders would have wanted some gambling (call it risk-taking), especially if it was smart and had positive expected returns—which it did for many years. Arguably, it was also in the shareholders' interest to gamble with the taxpayers' money. I judge that this was of much lesser importance than the misaligned CEO incentives.

So, should we try to claw back the bonuses, stocks, and options that Wall Street employees earned in the past from high-risk activities, such as subprime lending? Interesting question.

Confiscating the profits of those executives would also appeal to my sense of fairness. However, net-in-net, we are probably better off if we all swallow hard and let this go.

Should we limit executive compensation in the financial services sector?
It would be a bad idea to intervene too much, specifically, to restrict the salaries of executives who are coming in now. These new executives did not profit from their banks' past behavior, and they now have to do their best to fix the problems that their predecessors have caused. We want banks to be able to attract the best executives possible. Let's not shoot ourselves in the foot here.

Again, the current political proposal has argued for limiting future executive compensation in banks in which the government invests. This would punish the wrong party. It is not future investment bankers (and credit ratings agencies) who committed the sins that led to the crisis, but past ones. Effective discipline should punish those that were responsible for the mess, not those who are responsible for cleaning it up. (Fortunately, the executive compensation constraints seem more like political theater than they do like binding constraints.)

Why did finance profs not raise an alarm before?
For the most part, we thought that banks had sold off the mortgages and mortgage derivatives. We thought that the risk was very dispersed. We had no idea. This was not even our fault: there are almost no requirements for banks to disclose the information that would have made it possible for academics or regulators to understand the risk.

Personal Advice

The remainder of this FAQ is less technically focused, and more for the layperson.

Who will be hit hardest by the current crisis?
All of us have been hit (and will be hit by the recession that will come), not only by the bailout, but more so by the loss in the value of our real estate and stocks. However, anyone working in the construction sector will be hit most. Also, many individuals working on Wall Street and in New York City will have a tough time.
What can I do to protect myself now?
You cannot have your cake and eat it, too. You are unlikely to make a killing if you follow this advice. It is the safer, but longer path.
What can I do to help the crisis dissipate?
Though not necessarily in your self-interest, buying products from companies that themselves actively purchase American goods in turn may also help. (This can be American or foreign firms—the point is that the money is likely to come back and help your own company and job.)
Is the crisis an opportunity?
It could be. For example, as of October 24, 2008, stocks are now much cheaper than they have been for a long time. They could be good investments. However, they are also riskier investments right now than they have been for a long time.

There is also another way in which this crisis may be an opportunity: you may realize that speculating on getting wealthy is not a good meaning of life.


Long-Run Economics

What are our real long-term economic problems?
Bad as these events of the last 3 months are, they are dwarfed by our real problems:
Is it the Republicans fault that income inequality has increased?
No. The returns to education and intellectual work relative to manual work have increased. This has happened in every developed country, not just the U.S. (Before you want to redistribute too much —some is definitely needed!—be aware that talent can move (or, not locate to the U.S. in the first place.)
Is it immigrants' fault that income inequality has increased?
No. See above.
What else can we do to improve the economy?
The next president should do the following: All of us need to get used to saving and investing more, and consuming less.
How optimistic are you that our current political system can execute good reform?
Not very.
How optimistic are you that the financial crisis will blow over?
Such financial crisis have occurred with some regularity, and then disappeared again. This one is deeper than others, so it may take longer. The economic crisis may last longer. Nevertheless, if we can reform our economic regulations, fix some of the problems noted above, and do so in an efficient manner, the U.S. economy could once again become the envy of the world.
