摘要：
Complementarities arise naturally in diverse models of optimal decision-making in a firm. Theoretical properties of supermodular functions provide a powerful tool for analyzing qualitative properties in such circumstances. This paper considers a general model of the firm and gives sufficient conditions for complementarities to hold and for optimal decisions to be monotone with a parameter. A variety of specific models of the firm are shown to satisfy these conditions. Necessary conditions delimit those models of the firm that may exhibit monotone optimal decisions.
