Abstract

Problem definition: Profit maximization is the default criterion in operations management and much of economics, but its pursuit achieves a firm's financial value only under stringent conditions. Otherwise: (A) Profit optimization is sub-optimal, but the proper operational criterion to maximize value can be determined clearly for a firm that is financed internally. (B) Identification of the organizational structure to coordinate decisions regarding working capital and operations properly is a by-product of the answer to (A). Methodology/results: The results emerge from the analysis of a Markov decision process model of a firm that makes periodic decisions regarding operations and working capital. The value of the firm is the maximal expected present value of the time stream of net payouts (cash dividends, stock dividends, and stock buybacks). That is one end of an axis on which the other end is profit. (a) Simple formulas connect the two criteria on the axis. The value corresponds to a perturbed profit criterion in which revenue is deflated. (b) Thus, the use of a straightforward profit criterion compromises value. (c) The analysis depends on whether a bankruptcy risk is present or not and, if present, how it is modeled. The paper analyzes two cases: no risk of bankruptcy, and risk of bankruptcy under Chapter 11 of the U.S. Bankruptcy Code. (d) If there is no risk of bankruptcy, profit-optimal and value-optimal decision rules have the same qualitative features, and the management of working capital should be subordinated to operations management. (e) These results are applied to models of inventory, a vertically integrated supply chain, a fishery and capacity management. Managerial implications: CFOs should mandate lower inventories than operations managers deem profit-optimal. CEOs should not subordinate operations management to working capital management.
