[Impact of new Spanish smoke-free legislation on the business activity of bars, cafes and restaurants].

OBJECTIVE: to analyze the impact of Spanish smoke-free legislation (Law 42/2010) on the business activity of bars, cafés, and restaurants.
METHODS: we used the micro-data from the Household Budget Survey for 2010 and 2011. The linking files allowed close follow-up of the households that remained in the sample for 2 consecutive years. Taking the year 2010 as the base reference for our analyses, we quantified how levels of consumption expenses on hospitality venues have changed over the years, differentiating between smoking households and non-smoking households.
RESULTS: the marginal effects of the first stage of the two-part model showed that the mean probability of expenditure on hospitality venues was 96% in smoking households and was 86% in non-smoking households. There were no statistically significant variations in the probability of expenditure between 2010 and 2011. The proportion of expenditure on hospitality venues in total household consumption expenditure in smoking households was 7.961% and 7.796% in 2010 and 2011, respectively. These proportions were 7.25% in 2010 and 7.272% in 2011 for non-smoking households. The difference in differences estimator, which takes into account both differences between years and households, showed no statistically significant differences in levels of household consumption.
CONCLUSIONS: the introduction of the Law 42/2010 has had no impact on the levels of household consumption expenses on hospitality venues. Changes in consumption expenses could be explained by sociodemographic characteristics (such as the number of children per household) and the impact of the economic crisis (unemployment and a decrease in household income).
