سرمایه های عمومی و رقابت ناقص

In this paper we consider a macroeconomic model in which public capital is a productive input and there is monopolistic competition in the product market. We analyze the effects of a permanent variation in public capital investment both in the short and in the long run. Finally, we show that the optimal provision of public capital under imperfect competition is higher than that associated with the first-best policy.
