摘要：In this paper we have analyzed existence, uniqueness and stability of a steady-state equilibrium in an overlapping generations model with monopolistic competition and free entry and exit of firms. We establish a strenghtened Inada condition that is sufficient to exclude global contraction for any given set of well-behaved preferences. We also establish sufficient conditions for a non-trivial steady-state equilibrium to exist, and also sufficient conditions for its uniqueness and global stability. We show that the size of mark-up over marginal cost and the particular mix of fixed costs play a crucial role in these conditions and consequently on the dynamic behavior of the economy
