Within a standard gravity framework I explore the impact of country size and trade liberalisation on extensive and intensive margins of imports across broad categories of goods. This allows testing hypotheses from two distinct strands of the trade literature, i.e., vertical integration versus...

Standard neo-classical trade theory predicts that trade liberalisation should cause a fall in wage inequality in developing countries through a decrease in the relative demand for skilled labour. Recent studies of a number of developing countries, however, find evidence to the contrary. Using a...

This paper analyzes the institutional arrangements governing the international transfer of input-embodied new technologies in agriculture. While developed countries characteristically allow "multiple channel" private and public technological transfer, developing countries often force technology...

This paper aims to investigate the determinants of productivity growth in the Tunisian economy context over the period 1976 to 2010. Our theoretical model incorporates as key variables, domestic innovation, human capital, distance to technology frontier and external technology spillovers through...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

Using data from patents, citations, inter-sectoral sales and customs, we examine the international diffusion of technology through imports of sectoral knowledge and production inputs. We construct measures of the flow of technology embodied in imports. These measures are weighted by...

This paper studies the effect of competition on firm innovation by developing a discrete-time endogenous growth model where multi-product firms do two types of innovation subject to friction in technology spillovers. Firms improve their existing products through internal innovation while...

Since the expansion of world trade in the 1980s, measures of inequality have risen not only in developed countries, but also throughout the developing world. This stylized fact is contrary to the predictions of classical trade theory that in countries with high endowments of unskilled labor,...
