Within the recent literature studying participation in international markets using micro data, a small number have suggested that firms benefit from their exposure to international markets. One channel considered for this role has been investments in R&D. A common finding in this literature is that firms involved in international trade are also more likely to also undertake R&D. In this paper w...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from "dirty" and "clean" inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii) optimal policy involves both "carbon taxes" a...

This paper quantifies the contribution of technology gaps to international income inequality. I develop an endogenous growth model where cross-country differences in R&D efficiency and cross-industry innovation adoption opportunities together determine equilibrium gaps, trade patterns, Countries with higher are richer have comparative advantage more innovation-dependent industries. calibrat...

We develop a dynamic model of intermediate goods trade in which the pattern and the extent of intermediate goods trade are endogenous. We consider a small open economy whose …nal good production employs an endogenous array of intermediate goods, from low technology (high cost) to high technology (low cost). The underlying intermediate goods technology evolves over time. We allow for endogenous ...

This paper has two main objectives. First, it estimates the impact of related and unrelated variety of European regions’ knowledge structure on their patenting activity. Second, it looks at the role of technological relatedness and extra-local knowledge acquisitions for local innovative activity. Specifically, it assesses how external technological relatedness affects regional innovation perfor...

This paper looks at the convergence clubs literature from a Schumpeterian perspective, and it follows the idea that cross-country differences in the ability to innovate and to imitate foreign technologies determine the existence of clustering, polarization and convergence clubs. The study investigates the characteristics of different technology clubs and the growth trajectories that they have f...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation– in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be diffi cult both because clean research must climb several rungs to catch up with ...

This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. A temporary Northern policy combining clean research subsidies and a trade tax can ensure sustainable growth but Northern ...

In this paper we conduct a series of field experiments in rural India in order to measure preferences related to risk, loss, and ambiguity. Disaggregating by data, we find that on average women are significantly more risk averse and loss averse than men, though the higher average risk aversion arises due to a greater share of women who are extremely risk averse. Through a series of two empirica...

A spatial dynamic panel data approach is adopted to study regional growth convergence in the U.S. economy. In the neoclassical growth model, regions and countries are assumed to be independent from each other, which may not be valid in the real world. We introduce technological spillovers into the neoclassical framework, showing that the convergence rate is higher and there is spatial interacti...
