An extensive literature stresses that currency misalignments are costly in terms of growth performance. However, these studies do not consider the direct and indirect effects of currency misalignments on other countries. In this paper, we analyze how misalignments of the dollar, the euro, and...

We develop a new methodology to identify high-end variety exporters in French firm-level data. We show that they do not export to many more countries, but they export to more distant ones. This comes with a greater geographic diversification of their aggregate exports. These facts are explained...

This paper quantitatively investigates the short- and long-run effects of liberalizing global migration on the world distribution of income. We develop and parametrize a dynamic model of the world economy with endogenous migration, fertility and education decisions. We identify bilateral...

This paper introduces multi-quality firms within a Schumpeterian framework. Featuring non-homothetic preferences and income disparities in an otherwise standard quality-ladder model, I indeed show that the resulting differences in the willingness to pay for quality among consumers generate both...

The ELIE scheme of Kolm taxes labour capacities instead of labour income in order to circumvent the distortionary effect of taxation on labour supply. Still, Kolm does not study the impact of ELIE on human capital formation and investment. In this paper, we build an overlapping generations (OLG)...

The benchmark of this paper is the Fujita and Thisse (2002) core-periphery model, which adds a R&D sector with skilled labor to create new varieties for the modern sector. The number of R&D firms increases not only with the number of existing patents and knowledge spillovers but also with the...

Our paper presents a new rationale for innovation by incumbents. We show that the possibility to price-discriminate between consumers having different levels of wealth is a sufficient incentive for the industry leader to overcome the Arrow (1962) effect and keep investing in R&D, even in the...

The empirical analyses show that public and private R&D are strongly intertwined. On the one hand, the existence of large direct spillovers from public R&D to private industry has extensively proven. Yet, both a substitutability and complementarity relationship between private and public R&D...

A prediction of the endogenous growth models with quality ladders is that there exists a negative relation between growth and the degree of market competition. The aim of this article is to shed light on the relation between competition and growth when horizontal and vertical innovations can...
