Building upon an original and fruitful research line, a recent paper by Hidalgo and Hausmann (2009) proposed new indicators of product sophistication and economic complexity constructed solely upon international trade data, in their Method of Reflections. The authors find their indicators for...

The reader will find in this paper a simple theoretical framework where to analyze the usual issues from environmental and economic growth literature, including the problem of global warming, the corresponding climate change, and the impact on economic system. This paper considers two...

Individuals with heterogeneous incomes occupy a territory divided into zones with unequal levels of amenities. Using the concept of land rent à la Ricardo, we propose a model determining the land rent in the different zones as well as the distribution of individuals across them. A land tax...

The paper provides a continuous-time version of the discrete-time Mitra-Wan model of optimal forest management, where trees are harvested to maximize the utility of timber flow over an infinite time horizon. The available trees and the other parameters of the problem vary continuously with...

One of the most salient features of developing economies is the existence of a large informal sector. This paper uses quantitative theory to study the dynamic implications of informality on wage inequality, human capital accumulation, child labor and long-run growth. Our model can generate...

This paper studies the effect of liberalizing the international mobility of college-educated workers on the world economy. First, we combine data on effective and desired migration to identify the net pool of foreign talents (NPFT) of selected high-income countries. So far, the EU15 has poorly...

Dans un modèle de croissance endogène reposant sur le concept de soutenabilité forte et intégrant une ressource de matière (naturellement recyclable) dont la productivité marginale est bornée, cet article reconsidère la "conjecture de Ricardo", à savoir l'éventualité d'une hausse...

Nous introduisons le concept d'empreinte carbone dans un modèle offre globale et demande globale avec formation imparfaitement concurrentielle des prix et salaires et en examinons les propriétés de l'équilibre en présence d'une politique climatique. Nous étudions deux instruments possibles...

This paper proposes an improved concept of educational mismatch that combines a statistical measure of over- and undereducation with the worker’s self-assessment of skill utilization. In that way, we account for worker heterogeneity in skills whose omission may generate biased estimates of the...

The paper investigates the welfare consequences of liberalizing migration and trade between the OECD countries. The key findings are that the aggregate welfare gains from zeroing the trade barriers in OECD are moderate (+ 1,5% in real GDP), whereas the impact of reducing the barriers for...
