Ergodic chaos is one of the most important concepts in the theory of nonlinear economics. Due to the lack of appropriate sufficient conditions, its reach has not been fully understood. In this paper a sufficient condition for ergodic chaos that covers non‐expansive dynamical systems is examined. By analyzing an endogenous growth model as an example, we discuss the breadth of models in which ergodic chaos can emerge. [ABSTRACT FROM AUTHOR]

We consider a dynamic two‐country model of trade with production externalities with an emphasis on the possibility of global indeterminacy, which means that the distribution of capital stocks in each country in the long run depends on households' expectations. Opening trade yields expectation‐driven fluctuations. Global indeterminacy may occur around the free trade steady states even when the autarkic steady states are saddle points in both countries, and it must happen when local indeterminacy occurs around the autarkic steady states in both countries.

This paper investigates the interlinkage in the business cycles based on expectation-driven fluctuations of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general equilibrium model with sector-specific externalities. We show that some country's expectation-driven fluctuations can spread throughout the world once trade opens even if the other country has determinacy under autarky. We thus prove that under free trade, globalization and market integration can have destabilizing effects on a country's competitive equilibrium. Finally, we characterize a configuration in which opening to international trade improves the stationary welfare at the world level but deteriorates the stationary welfare of the country that imports investment goods and exports consumption goods. We conclude that in opposition to the standard belief, international trade might not be beneficial to all trading partners in the long run. [ABSTRACT FROM AUTHOR]

This paper investigates the interlinkage in the business cycles of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general-equilibrium model with Cobb–Douglas technologies and linear preferences. We also assume decreasing returns in both sectors. We first identify the determinants of each country's accumulation pattern in autarky equilibrium, and secondly we show how a country's business cycle may spread throughout the world once trade opens. We prove indeed that under free trade, globalization and market integration may generate a contagion of the capital-exporting country's business cycles and thus have destabilizing effects on the capital-importing country.

This paper investigates the interlinkage in the business cycles of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general equilibrium model with Cobb-Douglas technologies and linear preferences. We also assume decreasing returns to scale in the consumption good sector. We first identify the determinants of each country's global accumulation pattern in autarky equilibrium, and secondly we show how a country's business cycles may spread throughout the world once trade opens. We thus give capital intensity conditions for local and global stability of competitive equilibrium paths. [ABSTRACT FROM AUTHOR]

This study investigates interlinkage among the business cycles of countries from the viewpoint of endogenous real business cycles. For this purpose, we build a simple perfect foresight equilibrium model with two countries and characterize the global dynamics of a free-trade equilibrium as well as that of each country's autarky equilibrium by means of the fundamental structure of an economy.
