The report leading to the creation of the SSRC in 1923 outlined several major challenges for social science: data collection, interpretation, measurement, and causality. This lecture will explore the extent to which newly available administrative datasets — linked together to create what is sometimes referred to as “big data” — can help address these challenges and contribute to our understanding of the causes and consequences of eviction and poverty in the United States. The lecture will draw heavily on a study of eviction in Chicago and New York, which is joint work with Robert Collinson, John Eric Humphries, Nick Mader, Davin Reed and Daniel Tannenbaum.

Mitigating greenhouse gas emissions and facilitating adaptation to climate change requires effective public investments, yet many policies and programs lack crucial evidence of their effectiveness. In low and middle income countries, the cost of putting resources toward ineffective policies is particularly high. This talk discusses two recent randomized controlled trials aimed at filling the evidence gap. The first tests novel approaches to reduce agricultural emissions in India. The second improves smallholder farmers’ resilience to climate shocks in Niger. Findings highlight the need for piloting before scaling up policy — in both projects, cost effectiveness was improved through innovative policy design.
