We consider the problem of allocating production capacity among multiple items, assuming that a fixed proportion of overall capacity can be dedicated exclusively to the production of each item. Given a capacity allocation, production of each item follows a base-stock policy, i.e., each demand triggers a replenishment order to restore safety stocks to target levels. We present procedures for choosing base-stock levels and capacity allocations that are asymptotically optimal.

We develop lower and upper bounds on the prices of American call and put options written on a dividend-paying asset. We provide two option price approximations one based on the lower bound (termed LBA) and one based on both bounds (termed LUBA). The LUBA approximation has an average accuracy comparable to a l,000-step binomial tree. We introduce a modification of the binomial method (termed BBSR) that is very simple to implement and performs remarkably well. We also conduct a careful large-scale evaluation of many recent methods for computing American option prices.

In this paper, we critically examine the recommended practice of matching currency footprints. We argue that while matching currency footprints reduces profit variability, this practice can also cause reductions in expected profitability, a point that appears to have been overlooked in current literature. The expected profit effects of matching depend on the trade-off between possible expected cost savings of sourcing abroad verses the loss of what we refer to as "strategic flexibility" in responding to competitors' pricing and quantity decisions.

This study investigates the manner in which consumers make investment decisions for mutual funds. Investors report that they consider many nonperformance-related variables. When investors are grouped by similarity of investment decision process, a single small group appears to be highly knowledgeable about its investments. However, most investors appear to be naive, having little knowledge of the investment strategies or financial details of their investments. Implications for mutual fund companies are discussed.
