This article explores the role of trading volume in making out-of-sample forecasts of stock market volatility around the time of the 24 October 1929 crash. Following the recent literature on volatility forecasting, we compare the performance of symmetric and asymmetric GARCH-class models....

This research documents the time series behavior of unemployment rates for Hispanics and whites over the period of 1976-2008. In particular, we provide insight as to how Hispanics fared relative to whites by examining the unemployment rate, the unemployment rate gap, and the cyclical component...

Disparities in educational attainment exist across states. There are costs, both to the individual and society, associated with low levels of educational attainment. This research estimates the costs of high school noncompletion in terms of income loss for each state. The results suggest that:...
