Differences in real interest rates across developed economies are puzzlingly large and persistent. I propose a simple explanation: Bonds issued in the currencies of larger economies are expensive because they insure against shocks that affect a larger fraction of the world economy. I show that...

Stocks with recent past high idiosyncratic volatility have low future average returns around the world. Across 23 developed markets, the difference in average returns between the extreme quintile portfolios sorted on idiosyncratic volatility is -1.31% per month, after controlling for world...

Over the period 1975 to 2005, the US dollar (particularly in relation to the Canadian dollar) and the euro and Swiss franc (particularly in the second half of the period) have moved against world equity markets. Thus these currencies should be attractive to risk-minimizing global equity...

We develop an international financial market model in which domestic and foreign residents differ in their beliefs about the information in economic signals. Similar to models of asymmetric information, we consider how informational advantages by domestic investors about local output impacts...

This paper surveys and assesses the academic literature on defining, measuring, and identifying financial contagion and the various channels by which it can occur. It also includes new empirical analysis of recent trends and causes of contagion, highlighting contagion risks in the euro area. The...

We show that Eurozone bank risks during 2007-2012 can be understood as a "carry trade" behavior. Bank equity returns load positively on peripheral (Greece, Ireland, Portugal, Spain and Italy, or GIPSI) bond returns and negatively on German government bond returns, a position that generated...

The recent crisis highlighted the importance of globally active banks in linking markets. One channel for this linkage is through how these banks manage liquidity across their entire banking organization. We document that funds regularly flow between parent banks and their affiliates in diverse...

This paper uses micro-level data on mutual funds from different financial centers investing in equity and bonds to study how investors and managers behave and transmit shocks across countries. The paper finds that the volatility of mutual fund investments is driven quantitatively by both the...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...
