Dutta (J. Econom. Theory, 1991, 55, 64?94) showed that long-run optimality of the limit of discounted optima when the discount rate vanishes is implied by a certain bound on the value function of the optimal program. We introduce a new method to verify this bound using coupling techniques.

We consider a continuous-time two-sector infinite-horizon model with sector specific externalities, endogenous labor and a concave homogeneous non-separable utility function. We show that local indeterminacy arises with a low elasticity of intertempo- ral substitution in consumption provided the...

We examine the properties of a two country dynamic Heckscher-Ohlin model that allows for preferences to be non-homothetic. We show that the model has a continuum of steady state equilibria under free trade, with the initial conditions determining which equilibrium will be attained. We establish...

We extend the dynamic Heckscher-Ohlin model in Bond et al. (2009) and show that if the labor intensive good is inferior, then there may exist multiple steady states in autarky and poverty trap can arise. Poverty traps for the world economy, in the form of Pareto dominated steady states, are also...

This paper formulates a model embedding the key ideas from Ronald Coase’s famous essay on the theory of the firm in a simple competitive equilibrium setting with anarbitrary number of firms. The model studies the structure of production when transaction costs and diminishing returns to...
