Trade Patterns and International Technology Spillovers: Theory and Evidence from Japanese and European Patent Citations

International diffusion of knowledge is important to both the speed of the world’s technology frontier expansion and income convergence across countries. For example, Eaton and Kortum (1996) estimate innovation and technology diffusion among 19 Organization for Economic Co-operation and Development (OECD) countries to test predictions from a quality ladders model of endogenous growth with patenting.

General Purpose Technologies and their Implications for International Trade

This paper develops a simple model of trade and “quality-ladders” growth without scale effects to study the implications of general purpose technologies (GPTs) for international trade. GPTs refer to a certain type of drastic innovations, such as electrification, the transistor, and the Internet, that are characterized by the pervasiveness in use, innovational complementarities, and technological dynamism. The model presents a two-country (Home and Foreign) dynamic general equilibrium framework and incorporates GPT diffusion within Home that exhibits endogenous Schumpeterian growth. The model analyzes the long-run and transitional dynamic effects of a new GPT on the pattern of trade and relative wages. The main findings of the paper are: 1) when the GPT diffusion across industries is governed by S-curve dynamics, there are two steady-state equilibria: the initial steadystate arises before the adoption of the new GPT and the final one is reached after the GPT diffusion process has been completed, 2) when all industries at Home have adopted the new GPT, Home enjoys comparative advantage in a greater range of industries compared to Foreign, 3) during the transitional dynamics, Foreign gains back its competitiveness in some of the industries that lost its comparative advantage to Home.

A growth model with qualities, varieties, and human capital: stability and transitional dynamics

This article analyses the stability properties of the steady-state and the transitional dynamics of an endogenous growth model with human capital, increasing-varieties R&D, and quality-ladders R&D [Strulik, H. 2005. “The Role of Human Capital and Population Growth in R&D-Based Models of Economic Growth.”

The End of Multi-Fibre Arrangement and Firm Performance in the Textile Industry: New Evidence

Using a sample of 321 textile and clothing companies for the years 1992 to 2010, this paper analyses the effect of quota phase-outs on firm-level efficiency in Pakistan following the end of the Multi-Fibre Arrangement (MFA). It highlights sectoral heterogeneity within the manufacturing industry as a result of MFA expiration. The empirical methodology uses the structural techniques proposed by Olley and Pakes (1996), and Levinsohn and Petrin (2003) in order to take care of endogeneity in the estimation of production functions. The results differ for the two industries: MFA expiration lead to an increase in the average productivity of textile producing firms but a significant reduction in the mean productivity of clothing producers. We offer a number of explanations for this outcome, such as a change in the input and product mix, entry by non-exporters in the clothing sector, and sectoral differences in quality ladders. A number of crucial policy lessons can be drawn from the findings of this study.
