We study the relationship between commodity taxation and the effect of entry with imperfect competition. We develop a simple general equilibrium model with imperfect competition in which consumers have variety preferences. As a result, we see that introducing specific taxes increases social...

The purpose of this paper is to study the mechanism that allows a new industry to become the leading industry, using a variety expanding model based on Grossman-Helpman (1991). For this, we introduce two types of industries, mature and new industries, which are characterized by the differences...

This paper studies a two-sector model of endogenous technical change in which expansion of each production sector is associated with sector-specific R&D investment. It is shown that the pattern of growth is sensitive to the specification of intersectoral technological spillover as well as to the...

We show that indeterminacy arises nadiscrete-time competitive two-country dynamic model of international trade in which externalities, imperfect competition, public goods, and government intervention are assumed away. The present model is a standard dynamic trade model in the sense that there is...

We formulate a two(-country) by two(-tradable good) by two(-factor) dynamic general equilibrium model of endogenous growth and international rade that has no market distortion. After deriving the conditions for a balanced growth path with incomplete specialization in both countries to exist and...

We present a specific utility function which generates Giffen behavior. The derived demand function of each good is not only continuous in its price and income but also partly increasing in its price and decreasing in income. Moreover, we show that Giffen behavior is compatible with arbitrary...

This paper introduces external habit formation into one of the basic models of endogenous growth in which continuing expansion of product variety sustains long-term growth. We assume that households consume a range of final goods and they set a benchmark level of consumption for each good. The...

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...
