This paper explores the welfare effects of international subsidies designed to expedite the production of global public goods. It distinguishes between the impact subsidies exert on behaviour and the impact subsidies exert on welfare. Subsidies that encourage recipients to contribute to the...

Inequality indices for self-assessed health and life satisfaction are typically constructed as functions of the cumulative distribution function. We present a unified methodology for the estimation of the resulting inequality indices. We also obtain explicit standard error formulas in the...

Developed countries may gain more than developing countries from the provision of a global public good: the greater their valuation of the good, the higher the productivity of developing countries’ contributions and the more developed countries derive satisfaction from altruism.

We use the delta method to derive the large sample distribution of multidimensional inequality indices. We also present a simple method for computing standard errors and obtain explicit formulas in the context of two families of indices.
