Skarbek, David. "Occupational Licensing and Asymmetric Information: Post-Hurricane Evidence from Florida." Cato Journal 28, no. 1 (Winter 2008): 73-82.
Federal, state, and county governments accept the argument that occupational licensing protects consumers and improves their welfare. This argument stands in stark contrast to the apparent rent seeking that occurs with licensing. In return for gains from state-created barriers to entry, coalitions built along occupational lines support politicians.
This article will show that government action in times of crisis is often inconsistent with its rhetoric. Licensing is typically justified on the grounds that market mechanisms will not mitigate the problems associated with asymmetric information. In the wake of Hurricanes Frances and Katrina, Florida reduced restrictions on construction contractors, yet in times of crises informational asymmetries are more likely to be problematic. By examining the volume of work completed, I find little evidence of significant detrimental effects from the policy change. Given the relative success of reducing restrictions and the government's explicit recognition of licensing's limiting effect on the availability of roofers, reform of licensing, at least to the extent done in crisis, should be adopted permanently.
