The theoretical framework presented here preserves many of the primary features of the standard neo-classical model, while introducing some modifications that transform it into an open economy endogenous growth model with knowledge accumulation. Knowledge accumulation is determined in part by...

FDI has received surprisingly little attention in theoretical and empirical work on openness and growth. This paper presents a theoretical growth model where MNCs directly affect the endogenous growth rate via technological spillovers. This is novel since other endogenous growth models with...

Global supply chains (GSCs) are transforming the world. This paper explores why they emerged, why they are significant and future directions they are likely to take along with some implications for policy. After putting global supply chains into an historical perspective, the paper presents an...

The aim of this paper is to understand whether international trade may enhance innovation and growth through an increase in competition. We develop a two-country endogenous growth model, both countries producing the same set of goods, with firm specific R&D and a continuum of oligopolistic...

This paper documents a decreasing trend in the geographical concentration of EU agro-food imports. Decomposing the concentration indices into intensive and extensive margins components, we find that the decrease in overall concentration indices results from two diverging trends: the pattern of...

This paper examines micro-level channels of how financial development can affect macroeconomic outcomes such as the level of income and export intensity. Specifically, the paper investigates theoretically and empirically how financial constraints affect a firm's innovation and export activities....

While there is general agreement that technology differences must figure prominently in any successful account of the cross-country income variation, not much is known on the source of these technology differences. This paper examines cross-country income differences in terms of factor...

We examine a model of R&D competition and cooperation in the presence of spillovers. Unlike virtually all the literature, however, we treat these spillovers as endogenous and under the control of firms. We show that it is then essential to make a number of distinctions that are ignored in the...

This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...

This paper presents a dynamic North-South general- equilibrium model where households have non-homothetic preferences. Innovation takes place in a rich North while firms in a poor South imitate products manufactured in North. Introducing non-homothetic preferences delivers a complete...
