We investigate whether a causal interpretation of the robust association between cognitive skills and economic growth is appropriate and whether cross-country evidence supports a case for the economic benefits of effective school policy. We develop a new common metric that allows tracking...

Economic development in Latin America has trailed most other world regions over the past four decades despite its relatively high initial development and school attainment levels. This puzzle can be resolved by considering the actual learning as expressed in tests of cognitive skills, on which...

Although many U.S. state policies presume that human capital is important for state economic development, there is little research linking better education to state incomes. In a complement to international studies of income differences, we investigate the extent to which quality-adjusted...

Expanded international data from the PIAAC survey of adult skills allow us to analyze potential sources of the cross-country variation of comparably estimated labor-market returns to skills in a more diverse set of 32 countries. Returns to skills are systematically larger in countries that have...

Growth has been high and widespread in the last decade in Africa. Whether this shift in Africa's fortune has impacted poverty has been a subject of controversy. This paper brings into focus recent evidence on the pace of poverty reduction in Africa and addresses whether or not previously held...

The literature on poverty convergence is sparse and much of the empirical evidence relies on Ravallion (2012) who found a lack of poverty convergence across some ninety Less Developed Countries (LDCs) during 1977-2007. This paper revisits cross-country poverty convergence using data from the...

Empirical evidence in the sparse literature on poverty convergence currently relies on cross-sectional analysis, where Less Developed Countries (LDCs) starting out poorer are found to have enjoyed no faster subsequent poverty reduction during the past three decades than those starting out...
