Abstract:  We study the housing market response to a nationwide policy that mandated the provision of energy efficiency information with all marketing material at the time of listing. Using the near universe of housing sales in England and Wales, we match in the energy efficiency status of the property from Energy Performance Certificates at the time of sale. We provide causal evidence of households willingness to pay for a higher energy rated property, documenting a 1-3% premium to a higher energy efficiency rating at the national level, and a 3-6% premium in the London market. We consider two potential responses of homeowners to the policy – short-run gaming of the ratings, and longer-run property improvements – finding no support for the former, but some evidence of the latter.

Abstract: This paper studies a 2013 reform in which the city of Camden, New Jersey dissolved the city police department and replaced it. While crime did fall in Camden following the reform, evidence from a synthetic control approach suggests that there was no additional effect attributable to the reform beyond the expected improvement given state and national trends of a general fall in crime. However, we do find evidence of a 50% improvement in clearance rates, particularly for violent crimes.

Abstract: Due to felon disenfranchisement laws (FD), more than 7.4% of Blacks are disenfranchised compared to only 1.8% of other Americans. We study the political consequences of this racial disparity. Our difference-in-difference setup exploits the unpredictable timing of changes in FD, while allowing for time-varying state heterogeneity. We find FD legislation causes a 1 - 2 point reduction in turnout overall, but double that amongst Blacks. This is too large to be a mechanical effect, implying FD substantially reduces turnout among enfranchised Blacks. Further results show that FD reduces the number of Black U.S. Representatives and also lead to more conservative state policy.

Abstract: This paper studies how Medical Marijuana laws (MML) affect the level and composition of crime. Using a generalized synthetic control estimator we find that MML are associated with a substantial increase in convictions for drug possession and trafficking. These effects are driven by younger criminals, the rates of such crimes by older criminals falls. Interestingly, such declines in possession and trafficking are also seen in drug use data which show substantial declines in the use of drugs other than Marijuana by older criminals, particularly opiates, and a large increase in Marijuana consumption. Data on police numbers rules out that this is an effect of increased policing. We interpret the results as being consistent with MML increasing the risks associated with participation in criminal labour market, inducing both exit and increased participation in more serious crimes.
