We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Knowledge in any country depends on the human capital of the countries it exchanges knowledge with. The diffusion of knowledge throughout the world explains a period...

We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Growth is generated through human capital accumulation and knowledge externalities. The available knowledge in any country depends on its connections to the rest of...

An establishment can improve its productivity by hiring workers from more productive establishments. Then, how important is worker reallocation for aggregate productivity growth? To study this question, I develop a general equilibrium model where knowledge transmits as workers reallocate from...

We present a multi-country theory of economic growth and R&Ddriven technological progress in which countries are connected by a network of knowledge exchange. Technological progress in any country depends on the state of technology in the countries it exchanges knowledge with. The diffusion of...

The accumulation of knowledge and its application to a variety of human needs is a discontinuous process that involves innovation and change. While much has been written on major discontinuities associated, for instance, with the rise of new technologies during industrial revolutions, other...

In this paper, we aim at re-assessing the undisputed positive relationship between innovation and economic growth by questioning the view that R&D (and formal knowledge in general) equates innovation and innovation equates regional growth. We rather propose that these linkages are strongly...
