When cheap fossil energy is polluting and pollutant no longer absorbed beyond a certain concentration, there is a moment when the introduction of a cleaner renewable energy, although onerous, is optimal with respect to inter-temporal utility. The cleaner technology is adopted either...

We consider a general control problem with two types of optimal regime switch. The first one concerns technological and/or institutional regimes indexed by a finite number of discrete parameter values, and the second features ecological-like regimes relying on given threshold values for given...

We study the Markov-perfect Nash equilibrium (MPNE) of a game between oil-importing countries, who seek to maintain the atmospheric carbon concentration under a given ceiling, and oil-exporting countries. The oil-importing countries set a carbon tax and the oil-exporting countries control the...

Cotton sectors are facing many issues which are quite well reported by online newspapers. Many issues are internal to the running of cotton sectors. They are little related to the international issue of market distortion, pertaining to the "cotton file" of the WTO. A number of issues impeding...

In this article, we propose a new method to estimate price effects on micro cross-sectional data using full prices that take into account household domestic production. We use behavioral microsimulations by subpopulations to analyze the redistributive impact of changes on Value Added Tax (VAT)...

This paper examines the relationship between environmental policy and growth when green preferences are endogenously determined by education and pollution. The government can implement a tax on pollution and recycle the revenue in public pollution abatement and/or education subsidy (influencing...

This paper examines the interplay between public education expenditure and economic growth in a two-sector model. We reveal that agents' preferences for services, education and savings play a major role in the relationship between growth and public education expenditures, as long as production...

Should a country invest more in human or physical capital? The present paper addresses this issue, considering the impact of different factor intensities between sectors on both optimal human and physical capital accumulation. Using a two-sector overlapping generations setting with endogenous...

This paper aims at clarifying the conditions under which financial globalization originates welfare gains in a simple endogenous growth setting. We focus on the capital-deepening effect of financial globalization in an open-economy AK model and we show that constrained borrowing triggers...
