This paper provides suffcient conditions on the technology and preferences, under which the optimal savings-consumption policy is unique, and a stationary Markov equilibrium exists for an overlapping generation economy. Comparing with Wang (1993), our conditions on the uniqueness of optimal...

This paper incorporates negative consumption externality embodying "jealousy" and "running away from the Joneses" into Guo and Lansing (2007)'s model with production externality and endogenous depreciation, and examines how consumption externality helps to generate equilibrium indeterminacy...

In this paper, we have obtained closed-form solutions in Cass-Koopmans growth models with heterogeneous agents. The relationship between the form of production function and the dynamics of income distribution is made explicit. We then use this relationship to determine what production structure...

In this paper, based on dynamic programming we investigate the military spending, trade and wealth accumulation in a stochastic endogenous growth model. For the Cobb-Dauglas utility function, explicit solutions of the optimal problem in the home country are obtained, and the optimal consumptions...
