This paper obtains a simple algebraic derivation of the transitional dynamics of a two-sector endogenous growth model. This paper finds that the return to capital and the growth rate of output fall over time on the transition path if the initial ratio of physical capital to human capital is...

Numerous studies on income convergence estimate the convergence equation derived for autarkic economies using data from the world that is increasingly integrated. This paper derives a convergence equation for a world integrated by trade from the standard Heckscher–Ohlin model with factor price...

This paper derives a convergence equation for a world integrated by trade. We find that factor price equalization reduces the rate of income convergence among economies with identical preferences and identical technologies. This finding hold true both in neoclassical growth models and in...

This paper derives the necessary and sufficient condition for the simple gravity equation to hold: the market share of an exporting country is constant across all importing countries. Specialization is just one example satisfying this condition. It holds in a variety of situations where multiple...

This paper examines tariffs and other policies designed to protect the domestic investment good industry in a small open economy. In a dynamic two-sector model, where a nontraded investment good competes with an imported investment good, the paper identifies two channels through which commercial...

This paper examines the effects of temporary protection in a model of Cournot competition under the learning curve. We show that when the protected firm can choose among multiple technologies subject to different scopes for learning, protection may hurt the long-run competitiveness of the firm...

This paper constructs a Cournot-Ricardo model of trade by incorporating Cournot competition in a Ricardian trade model. In this model, the share of intra-industry trade in bilateral trade volume decreases as trading partners become more different in terms of the industry distribution of labor...
