Research

 

Current Working Papers:

Work in progress:

  • Investments into Prevention of Disasters: The Case of Earthquakes in California. Three-year funded NSF research grant (approved), 2006-2009.
  • Environmental Altruism, Evidence from Germany. This research uses a unique 60GB data set of 'speeding behavior' on highways. I analyze ‘voluntary speed limits’ employing a regression discontinuity design.
  • The Impact of Drug Policies on Crime. This work uses changes in state precursor laws in 2005-2006 that limit access to ‘Sudafed’ to disentangle the effect of drug (methamphetamine) use on crime. See abstract, with G. Rafert, 2006.
