A Modified Heckscher-Ohlin Theorem under Quasi-Linear Utility Functions

Constructing a two-country, two-good, two-factor model of international trade under quasi-linear utility functions, we obtain a Modified Heckscher-Ohlin (MHO) Theorem that relates the trade pattern to the international distribution of factor endowments. We also show that the MHO Theorem survives imperfect competition and increasing returns.The Modified Heckscher-Ohlin Theorem, Quasi-linear utility function, Imperfect competition, Increasing returns to scale

Trade and Indeterminacy in a Dynamic General Equilibrium Model

This paper introduces sector-specific externalities in the Heckscher-Ohlin two-country dynamic general equilibrium model to show that indeterminacy of the equilibrium path in the would market can occur. Under certain conditions in terms of factor intensities, there are multiple equilibrium paths from the same initial distribution of capital in the world market, and the distribution of capital in the limit differs among equilibrium paths.Externalities, Economic models, Market

On dynamic Chamberlin-Heckscher-Ohlin trade patterns

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.

Trade Between Countries with Radically Different Preferences

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 price ratios are unique and negative and that there is a unique positive equilibrium free-trade price ratio, implying that the positive equilibrium free-trade price ratio is not bounded by the equilibrium autarkic price ratios. This finding contrasts sharply with the familiar Torrens-Ricardo and Heckscher-Ohlin propositionspreferences

Voluntary Contributions to a Public Good: Non-neutrality Results / Contributions volontaires, biens publics

We show that the famous neutrality result in the theory of public good contributions (Warr, Kemp, Bergstrom, Blume and Varian) depends crucially on the assumption that agents do not take into account the effect of their public good contribution decisions on the relative price of the private goods. Thus, the scope of applicability of their result is not as large as one might at first think. Our non-neutrality results hold even if all countries are identical in technology, preferences, and endowments. Nous démontrons que le théorème sur l’invariance du stock total d’un bien public par rapport à la distribution de revenus n’est valable que si les contributeurs ignorent l’impact de leurs contributions sur le prix relatif des biens privés. Par conséquent, le résultat de Warr, Kemp, Bergstrom, Blume et Varian n’a qu’une sphère d’application limitée. Nos résultats sur le manque de neutralité sont valables même si les préférences, les technologies, et les dotations de ressources de tous les pays sont identiques.public goods, voluntary contributions,

A Note on Transversality Conditions

We derive a new transversality condition (which we prove to be necessary) for a class of infinite horizon optimal control problems.Transversality condition, Optimal control theory

Relative Wealth, Status Seeking, and Catching Up

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 distribution of wealth to be independent of the initial distribution, and conditions for saddlepoint stability in a two-class model. Nous démontrons que si l'utilité est une fonction de la richesse relative, peut-être à cause de la recherche du standing, alors, sous certaines hypothèses concernant la courbature de la fonction d'utilité et de la fonction de production, les gens pauvres peuvent rattraper les gens riches. Nous donnons des conditions suffisantes pour que la distribution de richesse finale soit indépendante de la distribution initiale, ainsi que les conditions suffisantes pour la stabilité au sens du point de selle.Status seeking, relative wealth, catching-up, La recherche du standing, la richesse relative, le rattrapage

Indeterminacy in a Two-sector Endogenous Growth Model with Productive Government Spending

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 grows at the unique rate right from the beginning or (ii) it has a continuum of equilibrium paths whose growth rates commonly converge to the balanced growth rate. That is, unlike the original one-sector model, it has transitional dynamics in case (ii). We also show that the effects of small changes in some parameters on the balanced growth rate and the price of the consumption good in terms of the investment good are opposite between (i) and (ii).Public services, Indeterminacy, A continuum of equilibrium paths, Two-sector endogenous growth

Welfare Enhancing Capital Imports

This paper provides a model to consider the conditions under which an acceptance of foreign capital is welfare enhancing in a multi-commodity multi-factor framework. Contrary to the pessimistic conventional wisdom of capital imports and welfare, we provide a justification for the acceptance of foreign capital and the diversification of industrial structure in developing countries. A sufficient condition for the acceptance of foreign capital to be welfare enhancing is that all domestic factors move into the new export sector in equal proportion to the endowments of factors.foreign capital, export sector, tariff revenue, welfare
