Multiple Equilibria in a Dynamic Two Country Model

Show Summary Details


Some market distortional factors such as factor-generated externalities and imperfect competition can give rise to multiple equilibrium paths, or indeterminacy, in dynamic general equilibrium models. Despite numerous studies on indeterminacy in two-country models, it is assumed that either market distortional factors or inferiority in consumption (one good is an inferior good at the steady state) will make indeterminacy possible. This chapter considers a dynamic two-country model with technological differences and illustrates how indeterminacy can arise even without any market distortional factor and inferiority in consumption. In cases where a pure consumption good is more labour-intensive than a consumable capital good, the chapter demonstrates that multiple equilibrium paths arise when the former is inferior. In cases where a pure consumption good is more capital-intensive than a consumable capital good, multiple equilibrium paths can arise even when both goods are normal.
