We develop a simple approximation for multistage production-inventory systems with limited production capacity and variable demands. Each production stage follows a base-stock policy for echelon inventory, constrained by production capacity and the availability of upstream inventory. Our objective is to find base-stock levels that approximately minimize holding and backorder costs. The key step in our procedure approximates the distribution of echelon inventory by a sum of exponentials; the parameters of the exponentials are chosen to match asymptotically exact expressions.

The optimal number of items to be included in a service bundle for a profit-maximizing firm that uses pure components, pure bundling, or mixed bundling strategies is determined. When applied to Venkatesh and Mahajan's (1993) data, the number of events held is shown to have a substantial impact on firm profits. The pricing strategies of a nonprofit organization that seeks to maximize usage subject to a nondeficit constraint is also studied. Using the same data, it is shown that, compared to a profit maximizing firm, a usage-maximizing nonprofit organization 1. charges lower prices, 2.

It is an everyday marketplace occurrence that brands lose and gain share. However, a brand's sales gain or loss can be attributable to very different factors, and thus understanding the sources of sales gain or loss would seem to be an important aspect of a brand manager's job.
