Knowledge that Transforms

The Ho-Saunders model (1981) is extended to consider the case of loan heterogeneity. Pure interest spreads may be reduced when cross-elasticities of demand between bank products are considered. The resulting diversification benefits emanate from the interdependence of demands across bank services and products—a type of portfolio effect. Control over relative rate spreads, across product types, and the resulting ability to manipulate the arrival of transactions demands enables the financial intermediary to maintain a more active role in managing its inventory risk exposure.

We examine the stock price behavior associated with public offerings of common stock and convertible debt that are withdrawn by the issuing firm, as well as the stock price behavior associated with completed offerings. We find that stock returns are negative in the period from the announcement to the withdrawal, and are statistically insignificant from the announcement to the issuance. Stock returns are positive at the withdrawal and negative at the issuance. Furthermore, the average stock returns associated with withdrawals are significantly different from zero only when the reported reason for the withdrawals is unfavorable market conditions. Our evidence suggests that managers' decisions to withdraw equity offerings depend on recent stock price behavior, and that managers' decisions convey information about firm value to market participants.

A procedure is developed for the valuation of options when there are two underlying state variables. The approach involves an extension of the lattice binomial approach developed by Cox, Ross, and Rubinstein to value options on a single asset. Details are given on how the jump probabilities and jump amplitudes may be obtained when there are two state variables. This procedure can be used to price any contingent claim whose payoff is a piece-wise linear function of two underlying state variables, provided these two variables have a bivariate lognormal distribution. The accuracy of the method is illustrated by valuing options on the maximum and minimum of two assets and comparing the results for cases in which an exact solution has been obtained for European options. One advantage of the lattice approach is that it handles the early exercise feature of American options. In addition, it should be possible to use this approach to value a number of financial instruments that have been created in recent years.

This study provides evidence on joint characteristics of hourly common stock trading volume and returns on the New York Stock Exchange. Average volume traded shows significant differences across trading hours of the day and across days of the week. Average returns differ across hours of the day, and, to some extent, across days of the week. There is a strong contemporaneous relation between trading volume and returns and also a relation between trading volume and returns lagged up to four hours. Furthermore, the trading volume-returns relation is steeper for positive returns than for nonpositive returns.
