Using an extension of Lucas¡¯ model of endogenous growth with education externality, we show that an environmental tax may increase growth. This is because the tax makes physical capital accumulation less attractive, thereby correcting for the underinvestment by agents in human capital.

Income variablity is likely to increase wage inequality if poorer households are more vulnerable to shocks. Using a simple method to estimate risk-adjusted measures of wage inequality and data from Mexico, this note shows that safety nets could offset a good part of the impact of risk aversion...

This note applies tools from the stochastic dominance literature on poverty to environmental data in order to test in a robust way whether over-consumption and thereby depletion of natural resources is increasing over time. The method is illustrated with country data on per capita CO2 emissions.

We propose simple graphical methods to identify poverty-reducing transfer program reforms. The methods are based on Program Dominance curves that display cumulative program benefits weighted by powers of poverty gaps. These curves can be decomposed simply as sums of targeting dominance curves...

Dans cet article, nous utilisons et adaptons une approche par dominance stochastique proposée par Duclos, Makdissi et Wodon (2005) à l'analyse des dépenses publiques en éducation en Côte d'Ivoire. Nous montrons qu'une réallocation des dépenses publiques en éducation vers le niveau...

We propose graphical methods to determine whether commodity-tax changes are "socially efficient", in the sense of improving social welfare or decreasing poverty for large classes of social welfare and poverty indices. We also derive estimators of critical poverty lines and economic efficiency...
