The paper proposes an intertemporal equilibrium model with monopolistic competition and free entry to explain the nexus between business formation and medium run growth. An investment externality is identified that results in underaccumulation of capital in the decentralized market equilibrium...

The paper reviews an algorithm for the iterative solution of rational expectations models. It shows in detail how general equilibrium models with perfect foresight and intertemporally optimizing behavior must be set up to be solved numerically with the algorithm. Three examples of intertemporal...

The paper develops a unified general equilibrium model includingsavings with overlapping generations, investment and search unemploament. Long-run analytical results for the small open economy identify capital accumulation as a prime transmission channel. The effects of integration on...
