The observed pricing of when-issued securities would seem to violate the laws of one price in financial economics. Generally, when-issued shares sell at a premium over the original shares during the short time when both are traded. This paper examines whether this observed premium could be due...

This paper examines the ability of volume data to shed light on the source of persistence in stock-return volatility. A mixture model, in which a latent common factor restricts the joint density of volumes and returns, is used to relax the assumption of exogenous volume used in previous studies....

This article examines the persistence of the variance, as measured by the generalized autoregressive conditional heteroskedasticity (GARCH) model, in stock-return data. In particular, we investigate the extent to which persistence in variance may be overstated because of the existence of, and...

We examine the behavior of measured variances from the options market and the underlying stock market. Under the joint hypotheses that markets are informationally efficient and that option prices are explained by a particular asset pricing model, forecasts from time-series models of the...

The authors report results from experimental asset markets with liquidity traders and an insider where they allow bilateral trade to take place, in addition to public trade with dealers. In the absence of the search alternative, dealer profits are large--unlike in models with risk-neutral,...

This paper examines the turn-of-the-year effect, the firm size effect, and the relation between these two effects for a sample of over-the-counter stocks traded via the NASDAQ reporting system over the period 1973-85. The authors find results similar to those based solely on listed stocks. The...

This paper provides empirical support for the notion that autoregressive conditional heteroskedasticity in daily stock return data reflects time dependence in the process generating information flow to the market. Daily trading volume, used as a proxy for information arrival time, is shown to...

Much research has focused on the problem of selecting portfolios without the benefit of parametric measures of risk and return. In this paper, a Monte Carlo technique is used to isolate the extent and nature of the problems introduced by this practice. The technique is employed in the context of...

In this paper, a model of market reaction to stock splits is presented and tested. The auth ors argue that the announcement of a split sets off the following cha in of events: the market recognizes that subsequent to the (reverse) split ex-day, the daily number of transactions along with the raw...
