We examine short-run patterns in government bond returns after market-moving events. Our sample covers government bond series from 17 developed countries. We find that abnormal returns follow momentum for about two weeks following an event and then reverse for a period of up to 60 days after the...

In this paper, we empirically investigate the relationship between equity and credit market development and economic growth, in a sample of five very important 'emerging' markets. In particular, we employ a multivariate time-series methodology to test for long-run trends and causality between...

Because heterogenous and unknown shareholder utility functions make it difficult to define a corporate objective common to all shareholders based on utility, the traditional theory of the firm concentrates on wealth maximization as the main measure of performance. Using the concept of ranked...

We propose a theoretical framework for constructing a market proxy that corresponds to the ldquo;market portfoliordquo; of financial theory. We construct this proxy, analyze its determinants and test its efficiency and explanatory power over the period 1974-2003 with respect to the return...

The weak empirical evidence linking diversification and international equity flows calls into question the diversification paradigm at the international level and the analytical framework it implies. Using a novel measure of diversification that includes all the moments of the distribution of...

In this paper we use the Clark (1991) methodology to estimate the macroeconomic financial risk premium from 1985 to 1997 for Argentina, Brazil, Chile, Colombia, Mexico and Venezuela, the 6 Latin American countries with the largest stock markets, and test whether and to what extent it affects...

The concept of efficient portfolios plays an important role in modern financial theory and practice. Although there is an extensive and growing literature that focuses on testing portfolio efficiency, outside of mean-variance optimization, which has several serious shortcomings, no systematic...

This paper offers new evidence on informed trading around merger and acquisition announcements from the UK equity and options market. The analysis suggests that in about 25%-33% of events there is abnormal option trading volume during the month that precedes the announcement. Such evidence is...

Using well known US stock portfolios that are formed on B/M, long term reversals, momentum, and size, a long sample period (1965-2007), and the comprehensive sentiment index of Baker and Wurgler (2006), which captures the common variation of six commonly used proxies for sentiment, this paper...
