The Blanchard Danger

September 1, 2014

by Roger Koppl

Oliver Blanchard tells us “Where Danger Lurks”  in the macro-finance world.

The big theme is nonlinearity, which is a profoundly conservative move: DSGE modeling is just fine and we don’t need to rethink it at all. We just need to add in some nonlinearities. Blanchard does not tell how to calibrate a model with extreme sensitivity to initial conditions. But if the system is chaotic, it is also unpredictable, so how can you pretend to merely add nonlinearities to DSGE models?  It seems like a pretty direct contradiction to me. I mean, you can have the model in a trivial sense, of course. But calibration is an empty exercise that will not let you look around corners.

Blanchard’s second main message is alarming: We do need theoretical innovation, however, in measuring systemic risk. In the modern network literature on financial markets and cascades, one key point is risk externality. My portfolio choice makes your portfolio riskier. We need two things to fix this market failure. First, we need Pigou taxes, which cannot be calculated unless everyone tells the regulator his portfolio so that it can measure systemic risk and calculate a separate Pigou tax for each financial institution. Second, we need to reduce systemic risk. (“[S]teps must be taken to reduce risk and increase distance” from the “dark corners” of the macro-finance system.) In the network literature I suspect Blanchard is alluding to, this is to be done (at least in some of the articles) by having the regulator directly control the portfolios of financial institutions. (Names include: Acharya 2009; Beale et al. 2011; Caccioli et al. 2011; Gai, Haldane,and Kapadia 2011; Haldane and May 2011; and Yellen 2009, 2011)

I take a rather different view of both economic theory and the crisis in my recent IEA Hobart paper From Crisis to Confidence: Macroeconomics after the Crash.

Overall, Blanchard’s message is meant to be reassuring: We the smart macro-finance experts have now got the message on nonlinearities. So no further need to worry, we’ve got the situation in hand. To keep the system out of the “dark corners,” however, we will need more discretionary authority. You don’t mind trading off a bit of financial freedom for greater financial safety do you?

Instead of the Fed

November 5, 2013

by Jerry O’Driscoll


For the month of November, Cato Unbound features an essay by me on “The Fed at 100.” Over the course of a week, there will be comments by Larry White, Scott Sumner and Jerry Jordan. I will respond to these as appropriate.

“End the Fed” has become a political slogan. Long before that, however, there was a serious academic literature on the prospects for competitive banking. I examine that literature in my posting. One interesting aspect of that literature is that important papers on free banking came out of Federal Reserve banks in the 1980s.

I argue that “the literature on free banking demonstrates the viability of private, competitive banking without a central bank.” But we now have a system of central banking almost everywhere. The fact that the road not taken would have been a viable path does not mean that we can retrace our steps and take that path now.

I devote roughly half the posting to consideration of what it would take to end the Fed. It would be a formidable but not impossible task. It is generally acknowledged that to be viable, a system of competing currencies would need convertibility into something that is in inelastic supply. Historically that has been a commodity, and I suggest gold is as good as any (though many disagree about that). What are the prospects for a return to a commodity standard?

Central banking is historically linked to governments running deficits and needing them to be financed. That is equally true today. Central banks cannot be abolished until permanent deficits are abolished, and governments are shrunk down in size. What are the prospects for that?

I have just returned from a very important conference at the Mercatus Institute at George Mason University on “Instead of the Fed: Past and Present Alternatives to the Federal Reserve System.” As the title suggests, alternatives to central banking in the past and the future were discussed. All three discussants of my posting also participated in important roles at that conference. I was a discussant of three papers, including one by Scott Sumner. So I imagine we will be continuing our dialog at Cato Unbound.

One of the most interesting discussions was among advocates of Fed abolishment and of Fed reform. All agreed that we need better monetary policy now and into the future, regardless of our differences on the issue of free banking versus central banking. I will observe that it was encouraging that people as diverse as George Selgin, Scott Sumner, Ben McCallum and I were able to arrive at a consensus.

I invite everyone to visit Cato Unbound this month and follow the conversation.


Income Inequality Matters

March 26, 2013

by Roger Koppl

Income inequality matters. Let me say that again so you know I meant it: Income inequality matters. This statement may be surprising coming from a self-described “Austrian” economist and a “liberal” in the good old-fashioned pro-market sense. It shouldn’t be. It should be one of our issues. The surprise should be that we pro-market types have not spoken up more on this central issue, thereby letting it become associated almost exclusively with more or less “progressive” opinion.

This indifference to income distribution is all the more mysterious because pro-market thinkers generally support a theory of politics that tells us to watch out for ways the state can be used to create unjust privileges for some at the expense of others. We should expect the distribution of income to be skewed toward the politically powerful and away from the poor and politically weak. In a representative democracy “special interests” engage in “rent seeking” to get special favors. Those special favors enrich some at the expense of others. That’s what they are meant to do!

Wisconsin Policy Lab

August 20, 2012

by Chidem Kurdas

Paul Ryan is said to be influenced by Milton Friedman, Friedrich von Hayek and Ayn Rand. One might add that as the representative for Wisconsin’s first congressional district, he is from a state that has often been in the vanguard of policy thinking. Read the rest of this entry »

Regulation Czar’s Net Effect

August 5, 2012

by Chidem Kurdas

Cass Sunstein, the White House regulatory affairs chief, is going back to academia.  It is not clear why he chose this particular time to return to Harvard Law School, leaving behind what looked like an experiment to implement the notions he advocated.

Has he made a difference as federal overseer of rulemaking? The record is at best mixed, at worst a prime example of how academic ideas can enable political hypocrisy. Read the rest of this entry »

Top Young Economists Consider Their Future

July 27, 2012

by Roger Koppl

Ali Wyne of the big think  blog “Power Games”  recently posted an interesting set of comments on the theme “Empirics and Psychology: Eight of the World’s Top Young Economists Discuss Where Their Field Is Going.”  George Mason’s own Peter Leeson  was among the eight “top young economists” sharing their views.

Over at New APPS, the philosopher Eric Schliesser  summarizes the eight comments. “Bottom line: due to low cost computing and a data rich environment the future of economics is data-mining (this was clear from at least four of the comments). This is especially so because the young stars have lost faith in homo economicus (due to behavioral work and the crisis).”

Eric’s summary seems about right to me. There were eight fine minds sharing eight different visions, but two related themes dominated the comments. 1) The old rationality assumption is in trouble and we don’t quite know what to do about it. 2) Economics should be more data-driven now that we have what William Brock has labeled “dirt-cheap computing.” Read the rest of this entry »

The Unfairness of Taxi Fares

July 17, 2012


by Mario Rizzo

Some time ago I was accused by the noted economist and psychiatrist Professor Bradford DeLong of being a “psychopath” and “clinically crazy” because I suggested that people should not tip cab drivers in New York City. I do not intend to revisit that particular issue here.

This time I would like to take on the Taxi and Limousine Commission’s approval of a 17% fare increase for cab rides beginning in September. Read the rest of this entry »

Hundred Years of Bailouts

July 11, 2012

by Chidem Kurdas

After all that’s been said and written about financial crises, it is rare to come across useful insights.  Financing Failure. A Century of Bailouts by Vern McKinley documents a major continuity with past policy making. He shows that policies intended to prop up failing companies are nothing new—the same basic pattern has recurred time and again.

But there is one notable change: the bailouts grew ever larger and the agencies concerned with them ever more numerous. Anyone thinking about recent crises and future prospects would do well to keep these points in mind.  Read the rest of this entry »

Is Justice Roberts a Big Player?

July 9, 2012

by Roger Koppl

The Supreme Court upheld “Obamacare” because Chief Justice Roberts changed his mind. (It seems that “Obamacare” is no longer a pejorative.)  In this curious situation, a stalwart of the Federalist Society  has become a Big Player in healthcare markets.

A Big Player is a powerful actor who uses discretion to influence a market. In the long run, Big Players are government entities or the creations thereof. They are discretionary actors whose personal discretionary choices supplant known and simple rules. In other words, Big Players substitute the rule of men for the rule of law. The great theorist of the rule of law, A.V. Dicey, said in an important remark that the rule of law “means, in the first place, the absolute supremacy or predominance of regular law as opposed to the influence of arbitrary power, and excludes the existence of arbitrariness, of prerogative, or even of wide discretionary authority on the part of the government.”

Roberts has become a Big Player, and yet the Federalist Society is against that sort of thing. It is committed to the rule of law. Its attitude to the role of the courts is expressed in a passage from Federalist 78: “It can be of no weight to say that the courts, on the pretense of a repugnancy, may substitute their own pleasure to the constitutional intentions of the legislature…. The courts must declare the sense of the law; and if they should be disposed to exercise WILL instead of JUDGMENT, the consequence would equally be the substitution of their pleasure to that of the legislative body.” But the “judgment” of Justice Roberts in this case seems to be very much an “exercise” of his “will.”

Should we therefore castigate Roberts as a hypocrite or ideologue? I don’t think so.

The problem is not that Roberts secretly wishes to impose his personal will on the law. Indeed, the decision seems to be the most restrained possible. It was hardly an instance of “judicial activism” or “legislating from the bench” given Robert’s presumptive political opposition to Obamacare. The problem arises when sweeping measures such as the Affordable Care Act come before the Court. Such laws are ambiguous. Read the rest of this entry »

Remember Those Oil Speculators?

June 5, 2012

by Chidem Kurdas

Less than two months ago, President Obama claimed that speculators were (or at least might be) artificially driving up the price of oil—a notion that some politician or pundit  brings up every time gasoline looks expensive. The idea fades when the market changes direction. Thus in recent weeks, economies worldwide took a turn for the worse and the price of oil came down a notch. Read the rest of this entry »
