Endogenous International Technology Spillovers and Biased Technical Change in Agriculture

Abstract

This paper analyzes trade-related knowledge flows from an innovating country to other countries. It is assumed that knowledge is embodied in commodities traded between countries and that the potential productivity of this knowledge is determined by the local usability of foreign technologies. The usability of foreign knowledge is dependent on the local absorption capacity (such as knowledge infrastructure and human capital) and on structural differences (factor endowments or climate) between countries. In agriculture, a large portion of the knowledge is embodied in inputs which cause factor-biased technical change in the receiving sectors. Trade-related knowledge transmission is introduced in an applied multi-region general equilibrium model (GTAP) to study the macro-economic and sectoral impacts of knowledge spillovers and of trade policies. Endogenous embodied technology spillovers bear some important implications for trade policy, because protective measures preclude countries not only from cheaper imports but also from foreign technologies.
