Moral Hazard & Conditionality: The Gods of this Greek Tragedy

So here it is: the long-awaited, much anticipated bail out of Greece. Was there really ever any doubt? I guess there was a little - that's why Greek bond yields went up. But the break-up of the Eurozone? Com'on - wasn't gonna happen.

So why has this been such a tragedy? Why the bickering back and forth about whether Greece will get a bail-out and who will do the bailing?

The answer has to do with "moral hazard" and "conditionality."

Moral hazard rears its ugly head any time actors are insured against a risk.

Imagine how people would drive if they were completely insured against any damage to their cars - answer: a little more recklessly.

The auto-insurance industry deals with potential moral hazard with lots of institutions: deductibles, higher premiums for folks with poor driving records, different rates for different types of cars and drivers.

Imagine the kinds of risks that banks might take if they were completely insured against risk by the government... hmmm... Imagine - it isn't hard to do.

Why, they'd take risky bets, lending to people who had little chance of repaying - and then when the loan repayments didn't come, well, they'd just get bailed out by the government.

So, how do we address this kind of moral hazard? This one is tougher. See, if the big banks fail, we all suffer. That's what "too big to fail" is all about - we don't have a credible commitment to let them fail... unless we are willing to allow the whole financial system to fail - that is, none of us eat. Since we don't want to go hungry, and the banks know this, they understand that they are just too big to fail.

Congress is trying to figure out away to deal with this moral hazard. Their solutions have to do with passing preemptive laws. One law could be to require banks to lend less and keep more money in their vaults (this is what "deleveraging" and "capitalizing" are about). Another law being considered is to keep banks small. The financial system can survive if small banks collapse. so we've got a credible commitment to let them fail. Knowing this, the small banks will not take undue risks.

Now, imagine how governments would act if they were completely insured against the risk of defaulting on loans. Why, they'd borrow and borrow and borrow... and they'd never worry about paying anything back... Yeah - imagine that. Well, this is what Germany has been imagining lately... it's been a nightmare thinking about the signal it sends when Greece is bailed out. Portugal, Spain, Italy - they'll all realize that they can borrow and spend without limit, and in the end someone will bail them out. How, then, can Germany deal with this kind of moral hazard?

The answer: Conditionality. Conditionality is just a quid pro quo. You want loans? You've got to change your ways. We'll give you a li'l slice of the loan upfront. But before giving you the next slice in a few months, we're going to check your policies. If you're still misbehaving - eating more than your earning - we'll hold up the next installment of the loan. And that will be ugly. You won't be able to pay government workers or deliver public services. Investors will run scared from your country, and no one else will be willing to lend to you. You won't eat.

Note that conditionality attacks a country's very sovereignty. The "conditions" of the loan have to do with government taxes and spending - the very essence of politics. It is as though the lender has suddenly entered into a country's political arena. And when taxes go up while spending goes down, there are lots of people who lose - people who won't be very happy about conditionality.

So who's going to impose conditionality?

Germany & the Eurozone have the money to lend to Greece. And they likely have the credibility to crack the conditionality whip. But this is dirty work. Germany would be seen as the bad guy in Greece - indeed throughout Europe - if it were dictating to the Greek government how to run Greece. If only there were some kind of smokescreen that Germany could use... where they call the shots, but make it appear that someone else is cracking the whip.

That's where the International Monetary Fund (IMF) comes in. See, the IMF has been doing conditionality for years and years. And while the United States is the largest single vote-holder at the IMF, the combined power of the Eurozone easily surpasses American might. So, the Eurozone will be calling the shots. Bickering amongst Eurozone members like France and Germany can take place behind the secret doors of the IMF Executive Boardroom. And whatever emerges will be IMF policy.

So, be on the look out for protest signs in Athens bashing the IMF in coming months. Some will surely see through the IMF facade, realizing that Germany is really calling the shots. Others will see that Greece really sacrificed its sovereignty the day they gave up the drachma in favor of the euro. But the real devil here is moral hazard. And the solution conditionality.

North America needs a flag!

In a multi-polar world, regionalism may become the key to global governance and prosperity. For all of its current troubles, the European Union and the Euro are here to stay. The Chiang Mai Initiative is the latest in overlapping institutions in East Asia. South America already has a customs union in Mercosur, and there is talk of their own new Banco del Sur. For the United States, our best hope for a regional future is making NAFTA better and building fair cooperation with our neighbors to the north and south.

I like the idea of closer ties to Mexico and Canada. As improbable as unity may seem for us three today, our prospects are certainly brighter than one would have imagined for France and Germany in the first half of the last century. War torn and bitter for decades, look at them now - united under one flag of Europe. A united North America is our future - perhaps distant - and it's never too early to start dreaming of greater unity and prosperity together under one North American flag.

So that's where I decided to Google-image "NAFTA flag"... YIKES! The image I found - a blending of the US, Mexican, and Canadian flags - looks like somebody's nightmare. I am, of course, teasing - I appreciate the effort. And it is perhaps reflective of the fact that NAFTA has a long way to go before it brings about any unity to our region. But to forge a new North American regional identity, we need a new flag, not a blending of our current national flags.

If we are going to dream of a future together, we need a new symbol of North American unity - one that reflects our past, present, and future as a new unified region. We can all keep our old national flags, of course, but for the region, we need an original design.

So, I've decided to try my hand at a flag for all of North America. Here's my proposal:
















The triangle symbolizes:
  1. The greatness of the pyramids built by the native people of the Americas in Mexico long before the days of colonization
  2. The three sides represent the three core members of our regional cooperation, beginning with NAFTA: Canada, Mexico, and the United States
  3. Most importantly, a resemblance to the North American geographical territory, which is narrow in the southern tip of Mexico, and wide across north of Alaska and Canada

The color recalls the gold of the past and the prosperity of the region’s future


The blue background:
  1. Complements the map interpretation of the triangle: recalls the Atlantic and Pacific oceans which surround and unify us
  2. Blue signifies trust, unity, and loyalty

Some final thoughts - while I justify the blue and gold in terms of our own North American past, present, and future, any similarity to the European flag is not a coincidence. I think that Europe has led the way on regional integration and serves as a model for the world. Personally, I do think 12 stars is overdoing it a bit. I like the simplicity of design on a flag. The one I propose here reminds me of the minimalism of the Japanese flag. This simple design is still distinctively ours: the use of the triangle is original and fitting for our three countries and for our North American land mass. Using a symbol that represents our geography is inspired by the flag of the Gambia. Note that there's room for Central America and the Caribbean to join some day - but we're not adding more sides or more stars - let's keep the design simple: the triangle represents North American unity.

So there it is. Let me know what you think. And if you like it, please forward this to others who might be interested...

Foreign Aid, Fractionalizers, and V-Graphs on The Vreelander

Last month I was privileged to participate in a conference on foreign aid at Oxford University.

Why do governments provide foreign aid? To which countries? And with what effects on economic development?

These are questions we considered. The participants included academics, like me, as well as practitioners - and people who straddle both worlds. Now, sometimes we academics have trouble expressing our nuanced ideas in a readily accessible format for a broad audience. This is why I was happy to see an innovative way to present the results of sophisticated data analyses with a picture - and the name is just perfect for The Vreelander: V-Graphs.

Two graduate students from Columbia University, Jordan Kyle and Elizabeth Sperber, presented research they've done with Jonathan Blake on "foreign aid fractionalization." What is "fractionalization" about? Well, sometimes donor countries give a lump some of aid to a developing country to be used for a broad range of purposes, but other times, donor countries "fractionalize" their aid into small packages for a number of very specific projects.

Just about everybody who studies foreign aid condemns "fractionalization." It increases transaction costs, places additional costly burdens on the bureaucracy, and limits the use local knowledge to respond to changing circumstances.

So why would a donor country "fractionalize" aid?

Blake, Kyle and Sperber suggest that it may be a question of how much the donor trusts the developing country's desire and ability to use the aid effectively. The more the donor trusts the recipient, the more of a "lump sum" that may be provided. If the donor doesn't trust the recipient, the aid may be "fractionalized" so that the disbursements can be micromanaged from afar. If a developing country has a highly-reputed effective bureaucracy, a donor may trust it to do a good job, but if the country's bureaucracy is known to be inept, the donor may "fractionalize."

The scholars test this hypothesis on a wealth of data from many different donors. They find that the effect of the developing country's bureaucratic quality influences different donors in different ways. Lately, the United States, for example, fractionalizes aid less for developing countries with high-quality bureaucracies, and fractionalizes more for the developing countries with low-quality bureaucracies, just as one would expect. But not every donor country follows this pattern. Many countries don't seem to care about the bureaucratic quality of recipient countries. And still other countries - like France - actually fractionalize more for the high-quality bureaucracies and less for the low-quality bureaucracies. (Why would the French do this? A mystery.)

I could go on listing the effects country by country, but Blake, Kyle and Sperber have a better way to present the results with a picture - the V-Graph!

Just a li'l bit of background: when we perform statistical analyses, we look for two things: (1) the direction & magnitude of a correlation (positive, negative, or neutral) and (2) how strong the relationship is - that is, whether it's "statistically significant." These two concepts are presented as the "coefficient" and the "standard error." Roughly speaking, the "coefficient" is a summary of the best fit of a relationship - sort of like a mean or average. The "standard error" is a sense of dispersion... or how many of our cases really come close to the best fitted relationship - sort of like a standard deviation. In the social sciences, we often look for relationships that are statistically significant at the 95% level... That means we're 95% certain that we would not have estimated a given coefficient if the real relationship is just zero... 95% significance is indicated when the size of the coefficient is about twice size of the standard error (more precisely, the ratio must be 1.96 or greater). Blah blah blah...

Whoah! Did I lose you in the previous paragraph? No problem. All you need to know is that the relationship between foreign aid fractionalization and bureaucratic quality might be either positive, neutral, or negative. The V-Graph summarizes all this in three partitions:


(Click the pic to make it bigger.)

If a country lands in the red part, the relationship is negative and statistically significant. (Higher bureaucratic quality => less fractionalization, like we might expect.) In the yellow part, the relationship is neutral or null - it's not considered statistically significant. (Bureaucratic quality doesn't influence these donors.) And in the green part, the relationship is positive and statistically significant. (Higher bureaucratic quality => more fractionalization - this is strange.) So, the graph conveniently summarizes the different ways donors consider the bureaucratic quality of recipient countries. You can easily see that for the USA the effect is negative - the United States "fractionalizes" its aid less for countries with high quality bureaucracies that it trusts to do a good job. The effect for IRE is neutral - Ireland doesn't seem to care about the bureaucratic effectiveness of recipient countries. And the effect for FRA is positive... strangely, France fractionalizes their aid packages more for the countries with high-quality bureaucracies. (If you're unfamiliar with the abbreviations for some countries, this page might help.)

From a substantive point of view, the question of fractionalization is important. Breaking up aid into small projects can overburden a developing country's bureaucracy and can be an inefficient way to provide aid. (See, for example, Nancy Birdsall's work on this.) So, we want to understand why donors choose to fractionalize. There is a lot more to it than I've touched on here - I recommend checking out the full paper.

And for statistically-minded folks who'd like to use V-Graphs to present their findings, the code is available here, on Jordan Kyle's webpage. So nice when a scholar provides a public good like this :-)
