Current account imbalances have steadily increased in rich countries over the last 20 years. While the U.S. current account deficit dominates the numbers and the news, other countries, especially within the Euro area, are also running large deficits. These deficits are different from the Latin...

In this lecture, I argue that the efficiency cost of generous but well designed social insurance need not be very large, and that there is indeed a viable European model, based on three legs: competition in goods markets, insurance in labor markets, and the active use of macroeconomic policy

Our paper is an attempt to define the contours of the right macroeconomic strategy for China. In a nutshell, we believe that the package includes a decrease in saving, with a focus on private saving, an increase in the supply of services, in particular health services, and an appreciation of the...

We construct a utility-based model of fluctuations, with nominal rigidities and unemployment, and draw its implications for the unemployment-inflation trade- off and for the conduct of monetary policy. We proceed in two steps. We first leave nominal rigidities aside. We show that, under a...

In the 1970s, large increases in the price of oil were associated with sharp decreases in output and large increases in inflation. In the 2000s, and at least until the end of 2007, even larger increases in the price of oil were associated with much milder movements in output and inflation. Using...

The purpose of this lecture is to look beyond the complex events that characterize the global financial and economic crisis, identify the basic mechanisms, and infer the policies needed to resolve the current crisis, as well as the policies needed to reduce the probability of similar events in...

For a long while after the explosion of macroeconomics in the 1970s, the field looked like a battle field. Over time however, largely because facts do not go away, a largely shared vision both of fluctuations and of methodology has emerged. Not everything is fine. Like all revolutions, this one...

We characterize the macroeconomics performance of a set of industrialized economies in the aftermath of the oil price shocks of the 1970s and of the last decade, focusing on the differences across episodes. We examine four different hypotheses for the mild effects on inflation and economic...

In the second half of the 1990s, the prospect of entry in the euro led to an output boom and large current account deficits in Portugal. Since then, the boom has turned into a slump. Current account deficits are still large, and so are budget deficits. This paper reviews the facts, the likely...

Under central planning, many firms relied on a single supplier for critical inputs. Transition has led to decentralized bargaining between suppliers and buyers. Under incomplete contracts or asymmetric information, bargaining may inefficiently break down, and if chains of production link many...
