Profit maximization in a multi-product firm with impatient customers

In this paper, the standard model of profit maximization is extended to include multi-product production in a market characterized by impatient customers. A formal model is presented that includes price, delivery frequency, production run length per set-up and product range as endogenous variables. The model facilitates the analysis of the complex interactions between these variables and highlights the inherent problems relating to profit maximization. For example, offering a broader range of products and/or more rapid delivery may seem to be a sensible response for a multi-product firm with impatient customers in a scenario of depressed demand. However, the analysis shows that such strategies could be counterproductive.
