PTAs are generally negotiated without any tariff concessions or transfers to non-member countries. Can such a PTA benefit the neighbors’ welfare? In a two-good competitive equilibrium model in the absence of an entrepot, a PTA without concessions to the outsider will hurt the outsider’s...

Based on some elementary results on duality, the paper proposes a much simpler way of deriving the class of non-homothetic CES production functions which was derived as a solution to a partial differential equation that defines the elasticity of substitution.

Applying Atkeson and Kehoe's (2000) dynamic model to the dynamic Chamberlin-Heckscher-Ohlin approach, we examine the role of the timing of development (e.g., the removal of trade barriers) as a determinant of trade patterns.

We examine the role of radical international differences in preferences in determining patterns of international trade, given that the trading countries share a common technology and identical factor endowment ratios. It is characteristic of our model that the equilibrium autarkic commodity...

We consider a class of differential games with transition equations that are homogeneous of degree one. For any game G with a discount rate r, consider a Markov perfect equilibrium (MPE) with strategies that are linear in the state variables. We show that the time paths of the control variables...

We show that, if relative wealth appears in the utility function, for example due to status seeking, then under certain conditions on the curvature of the utility function and the production function, the poor will eventually catch up with the rich. We give sufficient conditions for the final...
