Good public policy needs to be evidence based. However, the evidence base is thin for many policy issues. How can policy makers best respond to such thin areas of research that are also quite likely to change over time? Our survey investigates the evolution of the econometric evidence base for...

A growing literature documents the existence of strategic political reactions to public expenditure in one jurisdiction on either neighboring or reference jurisdictions. The latter might give raise to downward expenditure spiral, or "race to the bottom". However, in ascertaining the empirical...

Good policy requires reliable scientific knowledge, but there are many obstacles. Most econometric estimates lack adequate statistical power; some estimates cannot be replicated; publication selection bias (the selective reporting of results) is common; and there is wide variation in the evidence...

Recently, there has been much discussion about replicability and credibility. By integrating the full research record, increasing statistical power, reducing bias and enhancing credibility, meta-analysis is widely regarded as 'best evidence'. Through Monte Carlo simulation, closely calibrated on...

Do institutions and culture affect environmental values? In this article we analyze 1,041 environmental valuations of 223 wetlands in 38 developing countries, to examine the effect of institutions and culture on environmental values. We assess three dimensions of institutional quality: economic...

The sharp rise in international migration is a pressing social and economic issue, as seen in the recent global trend towards nationalism. One major concern is the impact of immigration on housing. We assemble a comprehensive database of 474 estimates of immigration's impact on house prices in...
