The 20th Human Development Report has introduced a new version of its famous Human Development Index (HDI). The HDI aggregates country-level attainments in life expectancy, schooling and income per capita. Each year's rankings by the HDI are keenly watched in both rich and poor countries. The...

Empirical studies of tax and benefit incidence routinely ignore behavioral responses and measurement errors. This paper offers an econometric method of estimating the mean benefit withdrawal rate (marginal tax rate) allowing for incentive effects, measurement errors, and correlated latent...

In theory, it is possible that the persistent poverty that has emerged in many transition economies, is attributable to underlying, non-convexities in the dynamics of household incomes - such that a vulnerable household will never recover from a sufficiently large, but short-lived shock to its...
