Long-term real interest rates across the world have fallen by about 450 basis points over the past 30 years. The co-movement in rates across both advanced and emerging economies suggests a common driver: the global neutral real rate may have fallen. In this paper we attempt to identify which...

We analyze a recent paper that claims that dollarizing an economy in the presence of a "dollar shortage" will provoke an immediate sharp reduction in real output and welfare. We find many problems with the model that supports this conclusion: confusion about the nature of a dollar shortage and...

Does targeted financial development favor small firms or large ones? And how do resulting changes in the distribution of firm size affect aggregate outcomes? We assess the macroeconomic implications of known stylized facts from the finance literature regarding firm size and financial frictions...

It is high time we rediscovered the role of the financial cycle in macroeconomics. In the environment that has prevailed for at least three decades now, it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the...

Global current account imbalances have been at the forefront of policy debates over the past few years. Many observers have recently singled them out as a key factor contributing to the global financial crisis. Current account surpluses in several emerging market economies are said to have...

Many commentators have argued that if the Federal Reserve had followed a stricter monetary policy earlier this decade when the housing bubble was forming, and if Congress had not deregulated banking but had imposed tighter financial standards, the housing boom and bust - and the subsequent...

This paper attempts to explain the divergent output effects of currency crises through a very simple and intuitive model that relates the effects of a devaluation not only to the financial fragility of banks, but also to the degree of financial market imperfection. The model shows that countries...

Based on a detailed trade-level dataset, we analyze the proprietary trading behavior of German banks in the months directly preceding and following the Lehman collapse in September 2008. The default of Lehman Brothers was a shock to the German banking system that was both unexpected and...
