We examine the theoretical predictions that link acquirer returns to diversity of opinion and information asymmetry. Theory suggests that acquirer abnormal returns should be negatively related to information asymmetry and diversity-of-opinion proxies for equity offers but not cash offers. We...

Not all stock recommendation changes are equal. In a sample constructed to minimize the impact of confounding news, relatively few analyst recommendation changes are influential in the sense that they impact investors' beliefs about a firm in a way that could be noticed in that firm's stock...

Using a large panel of firms across the world from 1991-2006, we show that the median foreign firm has lower idiosyncratic risk than a comparable U.S. firm. Country characteristics help explain variation in the level of idiosyncratic risk, but less so than firm characteristics. Idiosyncratic...

Though overall bank performance from July 2007 to December 2008 was the worst since at least the Great Depression, there is significant variation in the cross-section of stock returns of large banks across the world during that period. We use this variation to evaluate the importance of factors...

In this keynote speech, I ask the question: Does the cost of capital differ for firms located in different countries? I argue that there are two ways to look at the cost of capital. First, there is the neoclassical perspective, which assumes that there are no agency problems. In integrated...

This paper argues that the cost of capital for firms in small countries should be estimated using the global CAPM rather than a local CAPM. Two related formulas showing the mistake made when using a local CAPM rather than a global CAPM are presented. the global CAPM is implemented for the case...

Despite the disappearance of formal barriers to international investment across countries, we find that the average home bias of U.S. investors towards the 46 countries with the largest equity markets did not fall from 1994 to 2004 when countries are equally weighted but fell when countries are...

The difficulties of the past year have convinced many observers that current risk management practices are deeply flawed, and that such flaws have contributed greatly to the current financial crisis. In this paper, the author challenges this view by showing the need to distinguish between flawed...

We merge portfolio theories of home bias with corporate finance theories of insider ownership to create the optimal corporate ownership theory of the home bias. The theory has two components: (1) foreign portfolio investors exhibit a large home bias against countries with poor governance because...
