A semiparametric additive model is used to study the relationship between protected area, income, trade, population, education, and political institutions in a sample of 89 countries. The results show the nonexistence of an environmental Kuznets curve in the data sample. The study also points...

This paper analyzes the transitional dynamics in a model of economic growth with endogenous technological change and two alternative sources of energy: renewable and non-renewable resources. The conditions for the existence and saddle point property of the steady state are given. Finally, we...

[fre] Nous utilisons un modèle semi-paramétrique partiellement linéaire pour étudier la convergence des régions européennes. Les données proviennent de la base Eurostat et portent sur 223 régions de l’Union européenne pour la période 1990-2000. Les résultats d’estimation indiquent...

The aim of this paper is to characterize the one-dimensional stochastic differential equations, for which the eigenfunctions of the infinitesimal generator are polynomials in y. Affine transformations of the Ornstein-Uhlenbeck process, the Cox-Ingersoll-Ross process and the Jacobi process belong...

This paper uses nonparametric methods to examine the convergence in CO<Subscript>2</Subscript> emissions per capita on a sample of 100 countries for the period 1966–1996. Industrial countries show a convergence pattern. However, there is little evidence of convergence for the whole sample. Copyright Springer 2005

This paper investigates the empirical relationship between deforestation, economic growth and population using a sample of 85 developing countries. The study suggests a U-shaped relationship between the rate of deforestation and income per capita for all groups of countries, in contrast to an...

We use two datasets to study the convergence process across European regions. Relying on Quah (1966a,1997), we examine the dynamics of income distribution and find evidence of polarization whatever the time horizon considered. Regions whose incomes were close together at an initial period...
