June 2011Global Crises and Equity Market Contagion
with Geert Bekaert, Marcel Fratzscher, Arnaud J. Mehl: w17121
Using the 2007-09 financial crisis as a laboratory, we analyze the transmission of crises to country-industry equity portfolios in 55 countries. We use a factor model to predict crisis returns, defining unexplained increases in factor loadings and residual correlations as indicative of contagion. We find statistically significant evidence of contagion from US markets and from the global financial sector, but the effects are economically small. By contrast, there has been substantial contagion from domestic equity markets to individual domestic equity portfolios, with its severity inversely related to the quality of countries’ economic fundamentals and policies. This confirms the old “wake-up call” hypothesis, with markets and investors focusing substantially more on country-specific charac...

April 2008Central Bank Communication and Monetary Policy: A Survey of Theory and Evidence
with Alan S. Blinder, Marcel Fratzscher, Jakob De Haan, David-Jan Jansen: w13932
Over the last two decades, communication has become an increasingly important aspect of monetary policy. These real-world developments have spawned a huge new scholarly literature on central bank communication -- mostly empirical, and almost all of it written in this decade. We survey this ever-growing literature. The evidence suggests that communication can be an important and powerful part of the central bank's toolkit since it has the ability to move financial markets, to enhance the predictability of monetary policy decisions, and potentially to help achieve central banks' macroeconomic objectives. However, the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy.

March 2005Stocks, Bonds, Money Markets and Exchange Rates: Measuring International Financial Transmission
with Marcel Fratzscher, Roberto Rigobon: w11166
The paper presents a framework for analyzing the degree of financial transmission between money, bond and equity markets and exchange rates within and between the United States and the euro area. We find that asset prices react strongest to other domestic asset price shocks, and that there are also substantial international spillovers, both within and across asset classes. The results underline the dominance of US markets as the main driver of global financial markets: US financial markets explain, on average, more than 25% of movements in euro area financial markets, whereas euro area markets account only for about 8% of US asset price changes. The international propagation of shocks is strengthened in times of recession, and has most likely changed in recent years: prior to EMU, the pape...

December 1999Does Inflation Targeting Increase Output Volatility? An International Comparison of Policymakers' Preferences and Outcomes
with Stephen G. Cecchetti: w7426
Aggregate shocks that move output and inflation in opposite directions create a tradeoff between output and inflation variability, forcing central bankers to make a choice. Differences in the degree of accommodation of shocks lead to disparate variability outcomes, revealing national central banker's relative weight on output and inflation variability in their preferences. We use estimates of the structure of 23 industrialized and developing economies, including nine that target inflation explicitly, together with the realized output and inflation patterns in those countries, to infer the degree of policymakers' inflation variability aversion. Our results suggest that both countries that introduced inflation targeting, and non-targeting European Union countries approaching monetary union...
