We compare institutional execution costs across the major U.S. exchanges using a sample of institutional equity orders in firms that switch exchanges. Execution costs including commissions are essentially indistinguishable across these exchanges. We also find the fraction of trading volume from momentum traders is greater on the NYSE than either the Nasdaq or AMEX and that orders are more likely to be worked by an institution's trading desk on the NYSE than on the Nasdaq. These results suggest that institutions actively manage execution strategies, taking into account characteristics of the markets in which they trade.

Trade credit is created whenever a supplier offers terms that allow the buyer to delay payment. In this paper we document the rich variation in interfirm credit terms and credit policies across industries. We examine empirically the firm's basic credit policy choices: whether to extend credit or to require cash payment; and, if credit is extended, whether to adopt simple net terms or terms with discounts for prompt payment. We also examine determinants of variations in two‐part terms. Results are supportive primarily of theories that explain credit terms as contractual solutions to information problems concerning product quality and buyer creditworthiness.

For corporations facing tax‐function convexity, hedging lowers expected tax liabilities, thereby providing an incentive to hedge. We use simulation methods to investigate convexity induced by tax‐code provisions. On average, the tax function is convex (although in approximately 25 percent of cases it is concave). Carrybacks and carryforwards increase the range of income with incentives to hedge; other tax‐code provisions have minor impacts. Among firms facing convex tax functions, average tax savings from a five percent reduction in the volatility of taxable income are about 5.4 percent of expected tax liabilities; in extreme cases, these savings exceed 40 percent.
