Background:In January 2011 Spain modified clean air legislation in force since 2006, removing all existingexceptions applicable to hospitality venues. Although this legal reform was backed by allpolitical parties with parliamentary representation, the government s initiative was contested bythe tobacco industry and its allies in the hospitality industry. One of the most voiced argumentsagainst the reform was its potentially disruptive effect on the revenue of hospitality venues. Thispaper evaluates the impact of this reform on household expenditure at restaurants and bars andcafeterias.Methods and empirical strategy:We use household expenditure micro-data for years 2006 to 2012 to estimate models for theprobability of observing expenditures and the expected level of expenditure. We apply a beforeafteranalysis with a wide range of controls for confounding factors and a flexible modeling oftime effects in order to identify the effects of the reform.Results:Our results suggest that the reform caused a 2% reduction in the proportion of householdscontaining smokers but did not cause reductions in households expenditures on restaurantservices or on bars and cafeteria services.
