The Unassuming Economist

I wrote a profile of economist Jeff Sachs that paints a positive picture of his achievements, particularly of his early work in Poland. A new book seems to be much more critical of Sachs, particularly of his recent work in Africa, according to this book review.

In 2012, the magazine Global Finance gave Stanley Fischer, then central bank governor of Israel, an A for his handling of the economy during the financial crisis. It was the fourth year in a row that Fischer had received an A. It’s a grade the former professor—who taught both Federal Reserve Board Chairman Ben Bernanke and European Central Bank (ECB) President Mario Draghi—cherishes: “Those were some tough tests we faced in Israel.”

Fischer stepped down as central bank governor in June this year after eight years in the job, bringing the curtain down on an extraordinary third act of his career. The second act was as the IMF’s second-in-command during the tumultuous period of financial crises in emerging markets from 1994 to 2001. This role as policymaker came after a rousing opening act in the 1970s and 1980s, during which Fischer established himself as a preeminent macroeconomist, one who defined the contours of the field through his scholarly work and textbooks. It speaks to Fischer’s success that stints as the World Bank’s chief economist in the 1980s and as vice chairman at Citigroup in the 2000s—which would be crowning achievements of many a career—come across as interludes between the main acts.­ For the full profile, continue reading here.

Jeffrey Sachs, peripatetic development economist

IT IS HARD to imagine a more accomplished—and more varied—career than that of Jeff Sachs. Harvard University granted him tenure in 1982 when he was only 28. In his early thirties, he helped Bolivia end its hyperinflation and restructure its debt. Only a few years later, he was drafting the Polish government’s blueprint for transition from communism to capitalism. Stints as advisor to the governments of Russia, Estonia, Burkina Faso, and India—among many others—followed. Sachs campaigned for debt relief for poor countries and, as an advisor to UN Secretary General Kofi Annan, developed a plan to achieve the Millennium Development Goals. Since 2002, as director of the Earth Institute at Columbia University, Sachs has set his sights even higher. The Institute, an interdisciplinary group of 850 people, addresses some of the world’s most difficult problems, from eradication of disease to global warming. Read more.

Olivier Coibion

Loungani: Congratulations on your selection as an IMF Fellow. Is this your first stint at a policy institution?

Coibion: Thanks, I’m thrilled to be here!  I worked for a year at the CEA [U.S. Council of Economic Advisers] in 2000-01. It gave me an enduring sense of how economic theory and empirical methods can help address policy questions and make a difference in people’s lives. And because I happened to be there during the transition from the Clinton to the Bush administration, it was fascinating to see the change in style and personalities—and in the dress code. The suits got much more sober and I even had to start wearing a tie once the Bush administration was in place.

Loungani: Dress is casual at the IMF over the summer. You see the suits out in full force in the fall. What will you work on during your year here?

Coibion: I’ll continue some of my work on inequality. One project will look at links between inequality and financial crises, which folks at the IMF have also studied. I’ve also been studying the impact of monetary policy on inequality—who gains, who loses when the Fed changes its policy. This gets debated in policy circles a lot but not much in academia. Ron Paul says that expansionary monetary policies, or debasing the currency as he always puts it, raises income inequality; people on the left like Jamie Galbraith say the opposite.

Loungani: What do you find?

Coibion: We find that expansionary monetary policy has typically reduced U.S. inequality in the short run. This suggests that when the central bank can’t cut interest rates any more—when rates hit the so-called ‘zero lower bound’, as is the case at present—inequality will be higher than it would be otherwise. To avoid these additional increases in inequality at a time of crisis, the government should use other tools, such as targeted fiscal policies. I hope to do some more work on this while I’m here. More generally, I’ll be studying how best to sequence fiscal and monetary policies when the multipliers—the impacts of the policies on the economy—associated with each may vary with the state of the economy.

Loungani: Do you think the Fed has done enough to promote recovery?

Coibion: I think the zero lower bound [on interest rates] has certainly limited the size of their response. They would be lowering rates further if they could.  But as the IMF’s latest review of the U.S. economy noted, the Fed still has a few options to further support economic activity, given the weak state of labor markets and given the significant downside risks that still exist.

Loungani: Do you think that to avoid hitting the zero lower bound in the future, central banks should raise the target rate of inflation?

Coibion: No, I don’t. A higher inflation rate also has economic costs. So raising the target inflation rate will confer the benefit that we’ll be less likely to hit the zero lower bound. But such episodes are rare. So the high benefits conferred on rare occasions have to be balanced against the small but frequent costs of having higher inflation. In some work I’ve done, it turns out that the costs consistently outweigh the benefits for inflation rates above 2%. So rather than raise the target rate of inflation to deal with future episodes like the Great Recession, I’d prefer the more aggressive use of temporary policies designed for precisely this kind of episode, such as additional quantitative easing or fiscal policy.
