This paper develops two extensions of the dynamic model presented in Melitz (2003). The first extension consists in the introduction of technology choice between three alternative production technologies: L, M and H. L is assumed to be the same as Melitz’s single production technology, while M...

This paper studies how network structure can affect the speed of adoption. In particular, we model the decision to adopt Python 3 by software packages. Python 3 provides advanced features but is not backward compatible with Python 2, which implies adoption costs. Moreover, packages form...

This paper studies the diffusion of multiple, related technologies among firms. The results suggest an endogenous acceleration mechanism of technology adoption: The more advanced a firm is in using a particular set of technologies, the more likely it is to adopt additional, related technologies....

We study how the adoption of foreign technology and local spillovers from such adoption contributed to late industrialization in a developing country during the postwar period. Using novel historical firm-level data for South Korea, we provide three empirical findings: direct productivity gains...

In the two-country Melitz (2003) model, unilateral trade liberalization is often cast as a reduction of iceberg transportation costs and wages are determined by a linear outside sector. We show that welfare results reverse when wages adjust and trade frictions are revenue-generating tariffs.

Railroad access can accelerate the technological progress in the industrial sector and therefore induce structural change and urbanization, the two common features of modern economic growth. I examine this particular mechanism in the context of Japanese railroad network expansion and modern...

Railroad access may accelerate technological progress in the industrial sector and induce structural change and urbanization - the two common features of modern economic development. By digitizing novel datasets of factories and railroad networks in late 19th- and early 20th-century Japan and...

Firms in Kenya rely on technologies such as computers, cell-phones, and generators to overcome constraints associated with regulations, infrastructure, security, workforce, corruption, and finance. This study shows that such reliance has significant positive impacts on productivity as measured...
