This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. In the case of cross-sectionally correlated...

In the book Myth and Measurement, Card and Krueger (1995) examine the economic impact of the 1989 minimum wage hike on the welfare of 110 firms which employ a disproportionate number of minimum-wage workers. Their results show mixed evidence that excess returns associated with news about the...

Using university admission cutoffs that generate exogenous variation in college-major choices, we provide causal evidence that enrollment in a business or economics program leads individuals to invest significantly more in the stock market, earn higher portfolio returns, and ultimately...

This paper empirically examines the degree of persistence in four precious metal prices (i.e., gold, palladium, platinum, and silver) during the last four U.S. recessions. Unit root tests and fractional integration techniques suggest that gold still is the most prominent safe haven asset within...

How does factor accumulation affect the pattern of international specialization and returns to capital? We provide a new integrated treatment to this question using a panel of 44 developing and developed countries over the period 1976-2000. We confirm the Heckscher-Ohlin prediction that, with...

By allowing for imperfectly informed markets and the role of private information, we offer new insights about observed deviations of portfolio concentrations in domestic relative to foreign risky assets, or "home bias", from what standard finance models predict. Our model ascribes the "bias" to...

This study argues that the promotion of union goals could have positive, negative, or neutral effects on risk adjusted return performance. Moreover, the union's ability and incentive to use pension assets to promote union goals will vary with the design of the pension. Using panel data on over...

Slow onset climate change has the potential to cause significant migration flows. Scientists have recently made considerable efforts to quantify these flows based on empirical methods. However, the literature on international migration has failed to come to a clear conclusion as many studies...
