We study the effect of technological progress on the optimal transition to a renewable energy-fueled world economy. We develop a dynamic general equilibrium model where energy is used as an input in production and can come from fossil or renewable sources. Both require the use of capital, which...

We analyze the adoption of green technology in a dynamic economy affected by random shocks where demand spillovers are the main driver of technological improvements. Firms' beliefs and consumers' anticipations drive the path of the economy. We derive the optimal policy of investment subsidy and...

This paper examines how product market competition affects firms’ timing of adopting a new technology as well as whether the market provides sufficient adoption incentives. It shows that adoption dates differ not only among symmetric firms but also among markets with Cournot and Bertrand...

Environmental regulations have consistently been found to spur innovation in ‘clean' technologies, with one significant exception. Past cap-and-trade programs have encouraged adoption of existing pollution control technologies, but had little effect on innovation. Several explanations have...

This paper develops a new open-economy endogenous growth model where technology diffusion allows for a stable and non-degenerate world income distribution. In accordance with the empirical literature, I find that country characteristics such as the social infrastructure, the degree of openness,...

Climate research suggests that global warming will lead to more frequent and more extreme natural disasters. Most disasters are local events with effects on local economic growth. Hence, assessing their economic impacts with the help of econometric country-level analysis may lead to biased...

The aggregate economic impact of any developmental project depends on its effects within the chosen administrative region as well as its economic spillovers into other regions. However, little is known about how these spillovers propagate through geographic, ethnic and road networks. In this...

We study backstop adoption and carbon dioxide emission paths in a two-region model with unilateral climate policy and non-renewable resource consumption. The regions have an equal endowment of the internationally tradable resource and a backstop technology. We first study the case of a...

Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...

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...
