The Cost of (Equity) Capital

By James Kwak

For years, the world’s largest banks have been up in arms over threats by regulators to increase their (equity) capital requirements. Making banks hold more capital, they argue, will force them to reduce lending and will increase their cost of funding, making credit more expensive throughout the economy. One of the chief defenders of the megabanks has been Josef Ackermann, CEO of Deutsche Bank until last year and also chair of the Institute of International Finance, which claimed that higher capital requirements would reduce economic output by a whopping 3.2 percent.

Anat Admati and Martin Hellwig have been tirelessly debunking the myth that higher capital levels will force banks to curtail lending and torpedo the global economy, most recently in their excellent new book, The Banker’s New Clothes. Some of the arguments against higher capital requirements are simply incoherent, like the idea that banks would be forced to set aside capital instead of lending it. (Capital is the difference between assets and liabilities, not cash that you put somewhere for safekeeping; were it not for reserve requirements, which are something else, a bank could lend out 100 percent of the money it can raise.)

With Great Power . . .

By James Kwak

A friend brought to my attention another example of how Excel may actually be a precursor of Skynet, after the London Whale trade and the Reinhart-Rogoff controversy. This comes to us in a research note from several years ago by several bioinformatics researchers titled “Mistaken Identifiers: Gene name errors can be introduced inadvertently when using Excel in bioinformatics.” The problem is that various genes have names like “DEC1” or identifiers like “2310009E13.” When you important those text strings into Excel, by default, the former is converted into a date and the later is converted into scientific notation (2.310009 x 10^13). Since dates in Excel are really numbers behind the scenes (beginning with January 1, 1900), those text identifiers have been irretrievably converted into numbers.

This problem is related to what makes Excel so popular: it’s powerful, intuitive, and easy to use. In this case, it is guessing at what you really mean when you give it data in a certain format, and most of the time it’s right—which saves you the trouble of manually parsing text strings and converting them into dates (which you can do using various Excel functions, if you know how). But the price of that convenience is that it also makes it very easy to make mistakes, if you don’t know what you’re doing or you’re not extremely careful.

There are workarounds to this problem, but as of 2004, it had infected several public databases. As the authors write, “There is no way to know how many times and in how many laboratories the default date and floating point conversions to non-gene names have adversely affected an experiment or caused genes to ‘disappear’ from view.”

Can You Say “Bubble”?

By James Kwak

Yesterday’s Wall Street Journal had an article titled “Foosball over Finance” about how people in finance have been switching to technology startups, for all the predictable reasons: The long hours in finance. “Technology is collaborative. In finance, it’s the opposite.” “The prospect of ‘building something new.'” Jeans. Foosball tables. Or, in the most un-self-conscious, over-engineered, revealing turn of phrase: “The opportunity of my generation did not seem to be in finance.”

We have seen this before. Remember Startup.com? That film documented the travails of a banker who left Goldman to start an online company that would revolutionize the delivery of local government services. It failed, but not before burning through tens of millions of dollars of funding. There was a time, right around 1999, when every second-year associate wanted to bail out of Wall Street and work for an Internet company.

The things that differentiate technology from banking are always the same: the hours (they’re not quite as bad), the work environment, “building something new,” the dress code, and so on. They haven’t changed in the last few years. The only thing that changes are the relative prospects of working in the two industries—or, more importantly, perceptions of those relative prospects.

Wall Street has always attracted a particular kind of person: ambitious but unfocused, interested in success more than any achievements in particular, convinced (not entirely without reason) that they can do anything, and motivated by money largely as a signifier of personal distinction. If those people want to work for technology startups, that means two things. First, they think they can amass more of the tokens of success in technology than in finance.

Second—since these are the some of the most conservative, trend-following people that exist—it means they’re buying at the top.

Frat Boys and Tech Companies

By James Kwak

Matt Bai’s recent article on how Curt Shilling’s gaming company, 38 Studios, managed to secure a $75 million loan from the State of Rhode Island and then flame out into bankruptcy is a reasonably fun read. Bai’s main emphasis, which I don’t disagree with, is on Rhode Island’s Economic Development Corporation, which managed to invest all of its capital in a single company in a risky industry that, apparently, had failed to secure funding from any of the VC firms in the Boston area. Overall, this seems like another example of why government agencies shouldn’t be trying to act like lead investors.

But the story has another moral, which struck closer to home for me. Shilling apparently founded the company because he liked MMORPGs and because he wanted to become “Bill Gates-rich.” When the going got tough, in Bai’s words, Shilling “seemed to think that he could will Amalur into being, in the same way he had always been able to pitch his way out of a bases-loaded jam, even with a throbbing arm. His certainty reassured employees on Empire Street, who had no idea that he was running out of money.”

Software is hard. Really hard. And it’s even harder when you’re up against good competition. It has to be done right, and you cannot get it done twice as fast by working “twice” as hard. Too many software companies have been run into the ground by people who wanted to make a fortune but had no understanding of how software is built. Most of them are back-slapping frat boys who climbed the corporate hierarchy in sales, not world-famous athletes. But Curt Shilling, apparently, was just like them.

Protecting Boards from Their Own Shareholders

By James Kwak

I teach corporate law, and one of the topics in a typical introductory corporate law course is hostile takeovers. The central legal question is: to what extent is a board of directors allowed to undertake defenses against a takeover bid, even if (as is always the case) the potential acquirer is offering a premium over the current market price?

Whenever I teach one of these cases, I always bring up the nagging economic question: if the share price is $20, and Big Bad Raider is offering $30 in cash to each and every shareholder, where does the board get the chutzpah to claim that, under its leadership, the true value of the company is more than $30? (I understand the argument that Bigger Badder Raider might be convinced to pay more than $30, but the law, at least in Delaware, allows boards to use some takeover defenses to fend off any acquirer.) This always baffles me, but the law is premised on the idea that there is some fundamental value that is hidden deep inside the current board’s “strategic plans,” and that Big Bad Raider may rob shareholders of this fundamental value.

Fatal Sensitivity

By James Kwak

One more post on Reinhart-Rogoff, following one on Excel and one on interpretation of results.

While the spreadsheet problems in Reinhart and Rogoff’s analysis are the most most obvious mistake, they are not as economically significant as the two other issues identified by Herndon, Ash, and Pollin: country weighting (weighting average GDP for each country equally, rather than weighting country-year observations equally) and data exclusion (the exclusion of certain years of data for Australia, Canada, and New Zealand). According to Table 3 in Herndon et al., those two factors alone reduced average GDP in the high-debt category from 2.2% (as Herndon et al. measure it) to 0.3%.*

Are Reinhart and Rogoff Right Anyway?

By James Kwak

One more thought: In their response, Reinhart and Rogoff make much of the fact that Herndon et al. end up with apparently similar results, at least to the medians reported in the original paper:

So the relationship between debt and GDP growth seems to be somewhat downward-sloping. But look at this, from Herndon et al.:

More Bad Excel

By James Kwak

In 1975, Isaac Ehrlich published an empirical study purporting to show that the death penalty saved lives, since each execution deterred eight murders. The next year, Solicitor General Robert Bork cited this study to the Supreme Court, which upheld the new versions of the death penalty that several states had written following the Court’s 1973 decision nullifying all existing death penalty statutes. Ehrlich’s results, it turned out, depended entirely on a seven-year period in the 1960s. More recently, a number of studies have attempted to show that the death penalty deters murder, leading such notables as Cass Sunstein and Richard Posner to argue for the maintenance of the death penalty.

In 2006, John Donohue and Justin Wolfers wrote a paper essentially demolishing the empirical studies that claimed to justify the death penalty on deterrence grounds. Donohue and Wolfers attempted to replicate the results of those studies and found that they were all fatally infected by some combination of incorrect controls, poorly specified variables, fragile specifications (i.e., if you change the model in minor ways that should make little difference, the results disappear), and dubious instrumental variables. In the end, they found little evidence either that the death penalty reduces or increases murders.

Now the macroeconomic world has its version of the death penalty debate, in the famous paper by Carmen Reinhart and Ken Rogoff, “Growth in a Time of Debt.” Thomas Herndon, Michael Ash, and Robert Pollin released a paper earlier this week in which they tried to replicate Reinhart and Rogoff. They found two spreadsheet errors, a questionable choice about excluding data, and a dubious weighting methodology, which together undermine Reinhart and Rogoff’s most widely-cited claim: that national debt levels above 90 percent of GDP tend to reduce economic growth.

Memo to Employers: Stop Wasting Your Employees’ Money

By James Kwak

Now that I’m a law professor, people expect me to write law review articles. There are some problems with the genre—not least its absurd citation formatting system and all the fetishism surrounding it—but it’s not a bad way to make arguments about how and why the law should change in ways that might actually help people.

That was my goal in my first law review article, “Improving Retirement Options for Employees, which recently came out in the University of Pennsylvania Journal of Business Law. The general problem is one I’ve touched on several times: many Americans are woefully underprepared for retirement, in part because of a deeply flawed “system” of employment-based retirement plans that shifts risk onto individuals and brings out the worse of everyone’s behavioral irrationalities. The specific problem I address in the article is the fact that most defined-contribution retirement plans (of which the 401(k) is the most prominent example) are stocked with expensive, actively managed mutual funds that, depending on your viewpoint, either (a) logically cannot beat the market on an expected, risk-adjusted basis or (b) overwhelmingly fail to beat the market on a risk-adjusted basis.

Go For Gold

By Simon Johnson, April 1, 2013

In both 13 Bankers (2010) and White House Burning (published 2012, paperback just came out) James Kwak and I weighed the merits of going back on a global gold standard. In those books, we ended up siding with the prevailing fiat currency system – in which money is backed by nothing more than your confidence in central banks.

In the light of recent events – in the US and in Europe – I feel we should reconsider the arguments. On balance, I am now in favor of going back on gold for ten main reasons. Continue reading “Go For Gold” →

The Value of “Top Talent”

By James Kwak

From a Wall Street Journal article about The Children’s Investment Fund:

“[The fund] lost 43% in 2008, among the worst losses by a hedge-fund that year.”

“Both investors and employees defected during the crisis, with top talent leaving to start hedge funds of their own.”

“But with a 30% return in 2012 and a 14% gain this year, TCI has crossed its high-water mark.”

Makes you think.

Sir John Peace Should Resign As Chairman of Standard Chartered Bank

By Simon Johnson

On Thursday, March 21, Sir John Peace conceded that he lied to investors on March 5, 2013 when he said of Standard Chartered Bank,

“We had no willful act to avoid sanctions; you know, mistakes are made – clerical errors – and we talked about last year a number of transactions which clearly were clerical errors or mistakes that were made…”

Specifically, he now says that these remarks were “both legally and factually incorrect” because Standard Chartered had previously conceded that it deliberately laundered money.

In plain English, what Sir John said is called lying. Or, if you prefer the language of securities lawyers, he engaged in deliberate misrepresentation. He also violated Standard Chartered’s deferred prosecution agreement with US authorities.

Here is the full statement today.

Sir John should resign immediately as chairman of Standard Chartered. Continue reading “Sir John Peace Should Resign As Chairman of Standard Chartered Bank” →

Moving the Goalposts

By James Kwak

Ezra Klein yesterday highlighted one of the underlying problems with even apparently informed discussions of deficits and the national debt: the CBO’s “alternative fiscal scenario.” As opposed to the (extended) baseline scenario, which simply projects the future based on existing law, the alternative scenario is supposed to be more realistic. And it is more realistic in some ways: for example, it assumes that spending on Afghanistan will follow current drawdown plans, not a simple extrapolation of the current year’s spending. But the problem is that it has become excessively conservative in recent years—to the point where, as Klein says, “Policy makers, pundits and others almost exclusively use this model to stoke Washington’s deficit anxieties.”

“Some Of These Institutions Have Become Too Large”

By Simon Johnson

In a recent interview with PBS’s Frontline, Lanny Breuer – head of the criminal division at the Department of Justice – appeared to admit that some financial institutions were too big to prosecute. In the “too big to fail is too big to jail” controversy that ensued, lobbyists and other supporters of big Wall Street firms tried all kinds of complicated ways to spin Mr. Breuer’s words.

Their job got a lot harder yesterday when Eric Holder, the attorney general, stated clearly to the Senate Judiciary Committee,

“I am concerned that the size of some of these institutions becomes so large that it does become difficult for us to prosecute them when we are hit with indications that if you do prosecute, if you do bring a criminal charge, it will have a negative impact on the national economy, perhaps even the world economy,” (Watch the video for yourself.)

According to Mr. Holder, speaking as the top enforcer of the country’s laws, “some of these institutions have become too large.”

Senator Sherrod Brown (D, OH), a leading voice for making the biggest banks smaller, reacted in this way, Continue reading ““Some Of These Institutions Have Become Too Large”” →
