The authors analyze the relationship between ethnic polarization and the duration of civil wars. Several recent papers have argued that the uncertainty about the relative power of the contenders in a war will tend to increase its duration. In these models, uncertainty is directly related to the...

The paper formalizes and tests the hypothesis that greater exposure to big shocks induces stronger societal responses for adaptation and protection from future big shocks. Support for this hypothesis is found in various strands of the literature and in new empirical tests using cross-country...

Citizens have a right to accept any job offer in their country, but that right is not marketable or automatically extended to foreigners. Yet, some citizens have useful things to do if they could rent out their right-to-work, and there are foreigners who would value the new options for...

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...

Antipoverty policies in developing countries often assume that targeting poor households will be reasonably effective in reaching poor individuals. This paper questions this assumption, using nutritional status as a proxy for individual poverty. The comprehensive assessment for Sub-Saharan...

It is theoretically ambiguous whether growth of cities matters more to the rural poor than growth of towns. This paper empirically examines whether growth of India's secondary towns or big cities mattered more to recent rural poverty reduction, noting that data deficiencies have made this a...

Proxy-means testing is a popular method of poverty targeting with imperfect information. In a now widely-used version, a regression for log consumption calibrates a proxy-means test score based on chosen covariates, which is then implemented for targeting out-of-sample. In this paper, the...

Longstanding development issues are revisited in the light of a newly-constructed data set of poverty measures for India spanning 60 years, including 20 years since reforms began in earnest in 1991. The study finds a downward trend in poverty measures since 1970, with an acceleration post-1991,...

It is common for central governments, to delegate authority over the targeting of welfare programs to local community organizations - which may be better informed about who is poor, though possibly less accountable for getting the money to the local poor - while the center retains control over...

Adjustment programs often emphasize protecting social spending - especially pro-poor spending - from cuts. Yet the incidence of fiscal contraction - and hence the case for action to protect public spending on the poor at a time of overall fiscal austerity - is an empirical question, which the...
