International Financial Institutions have advocated the privatization of integrated agricultural monopsonies in developing countries with the hope that competition between private firms under a contract farming system would reduce inefficiencies in production and enable farmers to obtain a...

The poverty impact of indirect tax reforms is analyzed using sequential stochastic dominance methods. This allows agents to differ in dimensions that cannot always be precisely captured within the usual money-metric indicators of living standards. Examples of such dimensions include household...

This paper proposes graphical methods to determine whether commodity-tax changes are "socially improving", in the sense of improving social welfare or decreasing poverty for large classes of social welfare and poverty indices. It also derives estimators of critical poverty lines and economic...

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...

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...
