Abstract

This paper develops a dynamic game model of an asymmetric oligopoly with a renewable resource to reconsider welfare effects of increases in the number of firms. We show that increasing not only the number of inefficient firms but also that of Efficient firms reduces welfare, which sharply contrasts to a static outcome. It is discussed that the closed-loop property of feedback strategies plays a decisive role in this finding.
