Optimal Diversification

Working Paper: CEPR ID: DP3461

Authors: Joao Gomes; Dmitry Livdan

Abstract: In this Paper we show that the main empirical findings about firm diversification and performance are actually consistent with the optimal behavior of a firm that maximizes shareholder value. In our model, diversification allows a firm to explore better productive opportunities while taking advantage of economies of scale. The dynamic structure of our model allows us to examine several aspects of the relationship between firm diversification and performance in a very general setting.
