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...

We study how opening to trade affects economic growth in a model where heterogeneous firms can choose to adopt a new technology already in use by other firms. We characterize the growth rate using summary statistics of the profit distribution--the ratio of profits between the average and...

We study how opening to trade affects economic growth in a model where heterogeneous firms can adopt new technologies already in use by other firms in their home country. We characterize the growth rate using a summary statistic of the profit distribution—the mean-min ratio. Opening to trade...

The empirical analysis of the micro links between trade and knowledge diffusion allows us to distinguish among the key predictions of the theoretical literature on endogenous growth. This literature postulates that total factor productivity (TFP) is higher when trade gives access to a wider or...

Theoretical models of growth reveal that either exogenous or endogenous, technology is the main driving force behind the long-run economic growth. Furthermore, in the endogenous growth framework, diffusion of technology is the basic mechanism of per capita income convergence among countries....

This paper studies the effect of innovation uncertainty on the concomitant time path of firm valuations, technology adoption and growth in a setting which incorporates positive network externalities. The resulting stock market bubble, induced by uncertainty and accelerated by the externality...

The paper investigates the mechanics through which novel technological principles are developed and diffused throughout an economy consisting of a technologically heterogeneous ensemble of firms. In the model entrepreneurs invest in the discovery and in the diffusion of a technological principle...
