We develop a tractable general theory for the study of the economic and demographic impact of epidemics, and notably its distributional consequences. To this end, we develop a three-period overlapping generations model where altruistic parents choose optimal health expenditures for their...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

This article deals with cooperation issues in international pollution problems in a two dimensional dynamic framework implied by the accumulation of the pollutant and of the capital goods. Assuming that countries do reevaluate at each period the advantages to cooperate or not given the current...

The standard view about the relation between the Marshallian and the Walrasian approaches is that they are complementary to each other. My aim in this paper is to show that, on the contrary, they constitute alternative sub-research programs within the wider neoclassical paradigm. I make my point...

We study a trade-off between economic and environmental indicators using a two-stage optimal control setting where the player can switch to a cleaner technology, that is environmentally “efficient”, but economically less productive. We provide an analytical characterization of the solution...

The emergence of the crisis has given a new impetus to the criticism of economic liberalism. My claim in this paper is that such criticisms will be to no avail as long as the idea of liberalism remains homogenous. It should rather be considered that several degrees of liberalism coexist, which I...

Empirical evidence suggests that most firms operate in imperfectly competitivemarkets. We develop a search-matching model between wholesalers and retailers. Firms face search costs and form long-term relationships. Price bargain results in both wholesaler and retailer markups, depending on...

We show non-parametric identification of lagged duration dependence in mixed proportional hazard models for duration data, in the presence of competing risks and consecutive spells. We extend the results to the case in which data provide repeated realizations of consecutive spells competing...

This paper studies the effects of product and labour market deregulation on wage inequality and welfare. By constructing an analytically tractable model in which the level of product market competition and the wages are endogenously distributed, I show that even though deregulation in labour...

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)...
