Employing continuous arbitrage pricing principles, closed-form expressions for the term structure of interest rates as functions of two specific rates are developed. Model restrictions to the two one-dimensional submodels are tested and rejected, thereby supporting the hypothesis that the term structure is at least two-dimensional. Evidence is also presented that supports the view that the informational content of the term structure lies in its longer maturities.

This study examines the relation between common stock returns, trading activity and market value. Our results indicate that although firm size and trading activity are highly correlated, differences in trading activity are not the underlying reason for the firm size anomaly, the finding of systematic differences in risk adjusted returns across stocks of firms of different size.
