We investigate the misuse of R&D subsidies and evaluate its consequences for policy effectiveness. Developing a theoretical framework and using Chinese firm-level data for 2001-2011, we identify that 42% of grantees misappropri- ated R&D subsidies for non-R&D purposes, accounting for 53% of...

Arguably, one of the most important developments in the field of applied economics during the last decades has been the emergence of systematic policy evaluation, with its distinct focus on the establishment of causality.By contrast to the natural sciences, the objects of our scientific interest...

The credibility of standard instrumental variables assumptions is often under dispute. This paper imposes weak monotonicity in order to gain information on counterfactual outcomes, but avoids independence or exclusion restrictions. The outcome process is assumed to be sequentially ordered,...

This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

Education policy-makers and practitioners want to know which policies and practices can best achieve their goals. But research that can inform evidence-based policy often requires complex methods to distinguish causation from accidental association. Avoiding econometric jargon and technical...

This paper introduces Parameter Estimation by Raw Moments (PERM), a flexible method for evaluating a policy's impact on the parameters of an outcome distribution. Such parameters include the variance (E[Y 2 ]−E[Y] 2 ), skewness and covariance of two outcomes. PERM simplifies distributional...

Universal Credit (UC) was a large-scale reform of the UK welfare system reform, replacing six existing benefits. UC aimed to simplify claims and encourage more claimants into work. We identify its effect on mental well-being, treating the phased rollout from 2013-2018 as a natural experiment. We...
