This paper tests whether the correlation between wages and the spatial concentration of employment can be explained by unobserved worker productivity differences. Residential location is used as a proxy for a worker's unobserved productivity, and average workplace commute time is used to test...

Is lifetime inequality mainly due to differences across people established early in life or to differences in luck experienced over the working lifetime? We answer this question within a model that features idiosyncratic shocks to human capital, estimated directly from data, as well as...

This paper investigates the effects of public childcare availability in Italy on mothers' working status and children's scholastic achievements. We use a newly available dataset containing individual standardized test scores of pupils attending second grade of primary school in 2008-09 in...

To design studies that fill gaps in existing knowledge and build on innovations in research and practice, international early childhood researchers studying interventions and policies targeting early childhood development (ECD) need to sort quickly through the existing evidence. Researchers have...

This concept paper proposes a four-stage approach to in-country/region ECD program development, selection, and inquiry designed to build the evidence base required to guide program and policy decisions. The foundation of the approach is a strengths-based continuous program improvement framework....

There is growing state and national attention on addressing the achievement gap and increasing reading proficiency by 3rd grade. As state governments continue to face challenging fiscal conditions, there is a need to identify strategies that will lead to improved school readiness for at-risk...
