The paper represents a new reading of the traditional Ricardian theory of comparative advantages to tackle current challenges of environmental and climate policy. In the style of David Ricardo, it demonstrates that international trade is a positive-sum game in a twogoods, two-countries world...

It has long been known that the city-size distributions are fat tailed, drawing the interest of urban economists. In contrast, not much is known about the distribution of GDP at city level (henceforth referred to as gross metropolitan product, GMP). We build a model of the spatial economy that...

This paper analyzes socially responsible investment in the Walrasian model with uncertainty. It proves the following neutrality result: if each consumer's utility function with social responsibility is a function of her utility without social responsibility and asset holdings and if financial...

Does trade improve institutions and contribute to long run growth? I develop a theory of trade, in which trade liberalization provides incentive to change institutions in two ways. On the one hand, trade leads to specialization according to comparative advantage, expanding the industries that do...

Differences in environmental regulation between rich and poor countries have caused a geographical relocation of polluting industry from the former to the latter. In several cases the reduction in domestic emissions is at least partly compensated by an increase in trans-boundary pollution which...

This paper examines the effects of international trade and resource management in a two-country model where each country controls domestic harvest to prevent over-exploitation of an internationally shared renewable resource (e.g., fishery resources). We show that contrary to conventional wisdom,...

We show in this paper that trade in tasks can explain increasing resistance to globalization in industrialized countries. In a traditional trade model of a small open economy, we demonstrate that schooling provides protection against losses from trade if trade increases the relative price of the...

We propose a structural alternative to the Economic Complexity Index (ECI, Hidalgo and Hausmann 2009; Hausmann et al. 2011) that ranks countries by their complexity. This ranking is tied to comparative advantages. Hence, it reveals information different from GDP per capita on the deep underlying...

The last one and a half centuries have witnessed dramatic changes in the world economy. The service (tertiary) sector, which at the beginning of the 20th century was of little importance relative to agriculture and manufacturing, has become the dominant sector today, accounting for 80% and more...
