Using event studies we find statistically and economically significant, negative daily abnormal stock market returns prior to sovereign debt rating downgrade announcements. Instrumental variable techniques show that these findings are more pronounced in countries with lower institutional...

We examine the risk-return characteristics of a rolling portfolio investment strategy where more than six thousand Nasdaq initial public offering (IPO) stocks are bought and held for up to five years. The average long-run portfolio return is low, but IPO stocks appear as ‘longshots’, as...

Recent empirical work suggests a strong connection between the incentives money managers are offered and their risk-taking behavior. We develop a general model of delegated portfolio management, with the feature that the agent can control the riskiness of the portfolio. This represents a...

This Paper constitutes a first attempt to analyse the impact of the emergence of new funds on portfolio decisions of mutual fund managers who are evaluated on the basis of relative performance. Recent theoretical literature has pointed to the inefficiencies in portfolio selection caused by...

There is now extensive empirical evidence showing that fund managers have relative performance objectives and adapt their investment strategy in the last part of the calendar year to balance their performance in the early part of the year. However, emphasis was put on returns in excess of some...

This paper takes a systematic look at the portfolio choice problem faced by investment banks or funds investing in transition economies. We relate the performance of projects in the transition economies to the broader macroeconomic and international environment, which affect the project through...

International financial integration has greatly increased the scope for changes in a country’s net foreign asset position through the “valuation channel” of external adjustment, namely capital gains and losses on the country’s external assets and liabilities. We examine this valuation...

We develop a framework to explore the asset pricing implications of simultaneous supply shocks in multiple assets in a setting with limits-to-arbitrage. The portfolio approach in Greenwood (2005) is generalized to allow for asymmetric information and therefore net positions of arbitrageurs...

This paper provides a broad empirical examination of the major currencies' roles in international capital markets, with a special emphasis on the first year of the Euro. A contribution is made as to how to measure these roles, both for international financing as well as for international...

A number of studies have provided evidence of increased correlation in global financial market returns during bear markets. Others, however, have shown that some of this evidence may have been biased. We derive an alternative estimator for implied correlation based on portfolio downside risk...
