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

A Dynamic Two Country Heckscher-Ohlin Model with Non-Homothetic Preferences

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 conditions under which a static Heckscher-Ohlin theorem will hold in the steady state, and also conditions for a dynamic H-O theorem to hold. If both goods are normal, each country will have a unique autarkic steady state, and all steady state equilibria are saddle points. We also consider the case in which one good is inferior, and show that this can lead to multiple autarkic steady states, violations of the static H-O theorem in the steady state. Furthermore, there may exist steady state equilibria that Pareto dominate other steady states. These steady states will be unstable if discount factors are the same in each country, although they may exhibit dynamic indeterminacy if discount factors differ.two-country model, Heckscher-Ohlin, inferior good, multiple equilibria, indeterminacy

Financial integration and volatility in a two-country world

This paper investigates a two-country model of capital accumulation with country-specific production externalities. The main concern of our discussion is to explore the presence of equilibrium indeterminacy in an open-economy setting. In contrast to the existing studies on equilibrium indeterminacy in small-open economies, the present paper demonstrates that opening up international trade and financial interactions between two counties does not necessarily enhance the possibility of indeterminacy of equilibrium. It is shown that the results depend heavily upon not only on the degree of external increasing returns but also on the preference structures.Financial integration, Two-country growth model, Equilibrium determinacy, Preference structure

Preference Structure and Volatility in a Financially Integrated World

Financial Integration and Aggregate Stability

This paper explores a two-country model of capital accumulation with country-specific production externalities. The main concern of our discussion is to investigate equilibrium determinacy (aggregate stability) conditions in a financially integrated world economy. We show that the well-established equilibrium determinacy conditions for the case of small-open economy are still valid if heterogeneity between two countries is small enough. As the technological difference between the countries increases, the equilibrium determinacy conditions may diverge from those for the small country setting.financial integration, two-country model, equilibrium determinacy, social constant returns

A “Managerial” Trade Union and Economic Growth

By setting up a simple Romer-type (1989) endogenous growth model embodying a political trade union (rather than the traditional economic labor union), this paper explores the effects of unionization on unemployment, growth and welfare by highlighting the essence of internal conflict within the union. It is shown that the conflicting interests between the leadership and membership within the union play a decisive role in the unemployment, growth and welfare effects of unionization. Given the fact that taxation, besides unions, is another potential candidate in explaining the poor performance of employment and economic growth, we re-examine the taxation effects within the growth model with equilibrium unemployment caused by the presence of the trade union and compare our findings with those for the traditional full-employment growth model. In addition, the dynamic properties of the unionized economy are also examined, with particular emphasis being placed on the role of the trade union in the formation of equilibrium indeterminacy.Managerial trade union, collective bargaining, unemployment, economic growth

A two-country dynamic model of international trade and endogenous growth: multiple balanced growth paths and stability

We formulate a two-country endogenous growth model which explain joint determination of long-run trade patterns and world growth rates. After providing the existence and local stability of the continuum of balanced growth paths, we show that main standard trade propositions hold under some modifications and that, subject to certain conditions concerning social and private rankings of factory intensities between production sectors, the higher is the growth rate, the smaller is the volume of international trade among balanced growth paths in the continuum.

Indeterminacy and Market Instability

This note shows that indeterminacy arising from an economy exhibiting production with social constant returns to scale may be related to the instability of the consumption goods market equilibrium. Furthermore, trade does not contribute to indeterminacy; indeterminacy arises becasue each country’s equilibrium path is already indeterminate before trade.Indeterminacy, Market Instability

Autarkic Indeterminacy and Trade Determinacy

We extend the model of Nishimura and Shimomura (2002) to consider a two-country framework where under autarky indeterminacy arises in one country but determinacy in the other, and show that indeterminacy could be eliminated when trade takes place between the two.Indeterminacy, Trade, Two-Country Framework.

Autarkic Indeterminacy and Trade Determinacy

Most existing evidences for indeterminacy are obtained from analyzing models that do not consider trade. This paper considers an extension of Nishimura and Shimomura (Journal of Economic Theory, 2002) Heckscher-Ohlin framework by removing sector-specific externalities in one country while maintaining all other assumptions previously made by the authors. We show that even though indeterminacy arises under autarky, it can be eliminated when trade takes place with another country exhibiting saddle-path stability. Consequently, support for indeterminacy from calibrating an autarkic framework should be treated with some degree of caution.Indeterminacy, Trade, Two-Country, Heckscher-Ohlin
