Most economists take it for granted that a price mechanism is usually the most effective means of resource allocation. This paper compares two methods of allocating resources in the thoroughbred racing market: a price mechanism and bureaucratic restrictions. It is shown that a simple price...

This paper models stock returns as a function of three components: a constant expected return, the impact of the mechanism for executing trades, and a rational expectations error. We examine changes in these parameters using Goldfeld and Quandt's (1976) deterministic switching based on time....

The authors model stock returns as a stochastic function of a constant expected return and the financing costs resulting from delayed delivery, to examine three potential sources of instability in stock-return model parameter estimates.
