|August 2017||Welfare-Consistent Global Poverty Measures|
with Martin Ravallion: w23739
The paper provides new measures of global poverty that take seriously the idea of relative-income comparisons but also acknowledge a deep identification problem when the latent norms defining poverty vary systematically across countries. Welfare-consistent measures are shown to be bounded below by a fixed absolute line and above by weakly-relative lines derived from a theoretical model of relative-income comparisons calibrated to data on national poverty lines. Both bounds indicate falling global poverty incidence, but more slowly for the upper bound. Either way, the developing world has a higher poverty incidence but is making more progress against poverty than the developed world.
|April 2015||Benefit Incidence with Incentive Effects, Measurement Errors and Latent Heterogeneity: A Case Study for China|
with Martin Ravallion: w21111
In what is probably the largest cash transfer program in the world today China’s Dibao program aims to fill all poverty gaps. In theory, the program creates a poverty trap, with 100% benefit withdrawal rate (BWR). But is that what we see in practice? The paper proposes an econometric method of estimating the mean BWR allowing for incentive effects, measurement errors and correlated latent heterogeneity. Under the method’s identifying assumptions, a feasible instrumental variables estimator corrects for incentive effects and measurement errors, and provides a bound for the true value when there is correlated incidence heterogeneity. The results suggest that past methods of assessing benefit incidence using either nominal official rates or raw tabulations from survey data are deceptive. The ...
