We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is...

This statement outlines the objectives and policies of the new journal, Macroeconomic Dynamics, which is dedicated to the advancement of macroeconomics as a science. This Editorial is to appear at the front of the first issue of that journal and is copyright by Cambridge University Press.

We present a numerical version of the factor proportions (Heckscher-Ohlin-Samuelson) model of production in a small economy, built in Excel. The model features the most common graphical devices used to explain the model properties. It differs from earlier work in that the solution is embedded in...

The assumption of internationally identical factor intensity techniques may be one of the major causes of the HOV model's poor performance. To relax this assumption, detailed input-output data are required to compute the factor intensity techniques used in different countries; however, these...

Delays at the border for customs clearance are seemingly a central feature of the trade regime in the CIS states. Here, we argue that with queuing costs being endogenously determined in such circumstances tariff liberalization (even in the small economy case) can be welfare worsening since...

Market exchange is subject to an endogenously determined level of predation which impedes specialization and gains from trade. We construct a model in which utility-maximizing agents opt between careers in production and careers in predation. Three types of equilibria may emerge: autarky (with...

This paper proposes a new decomposition of welfare effects simulated by Computable General Equilibrium (CGE) models. Rather than relying on first order approximations, our approach is based on Taylor series approximations of CGE specifications and thus is path independent. This decomposition is...

Luego de examinar el marco teórico y conceptual de la teoría del crecimiento y del comercio internacional, se mide la eficacia de la apertura comercial impulsada por el TLCAN para fomentar el intercambio comercial. Asimismo, se evalúan los efectos de éste en el crecimiento económico de los...

The authors show how the transformation loci in the specific factors model (capital specificity) and the Heckscher-Ohlin-Samuelson model (capital mobility) can be rigorously derived and easily compared by using geometric techniques on the basis of Savosnick geometry. The approach shows directly...
