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 entrepôt, a PTA without concessions to the outside will hurt the outsider's welfare...

This note formulates a dynamic two-country (developed and developing countries) Chamberlin-Heckscher-Ohlin model of trade with endogenous time preferences a la Uzawa (1968). We examine the relationship between initial factor endowment differences and trade patterns in the steady state. In...

In two-sector infinite-horizon trade models with factor–price-equalization, convergence of aggregate capital-labor ratios and incomes does not occur because the Euler equations imply equal growth rate of consumption in all economies. In a two-country dynamic specific factors model, we show...

We extend the Barro (1990) model of endogenous growth to a two-sector one which consists of pure consumption and investment goods. It is possible that the extended version has a unique balanced growth rate such that for given initial values of state variables, (i) the extended model economy...

We offer a new proof of the maximum principle, by using the envelope theorem that is frequently used in the standard microeconomic theory. Copyright Springer-Verlag Berlin Heidelberg 2003

The Hicks-Ikema theorem, that a uniform expansion of a trading country's production set must benefit its trading partner if the preferences of the expanding country are homothetic, has been demonstrated under assumptions of the Lerner-Samuelson kind. It is shown here that the theorem remains...

This paper presents a pair of new equivalent conditions for a given n x n matrix of distributive shares to satisfy the Stolper-Samuelson criterion. Specifying n as four and making use of barycentric coordinates, the author gives geometric characterization to the equivalent conditions. Copyright...
