Resum

This article attempts to explain some facts that characterise the working of the supply side of the labour market in Spain,in relation to direct taxation. In particular, we briefly review the labour supply, models that have been estimated with Spanish data and some of the measures ofwell-being that may be calculated after their estimation. In the empirical analysis we use data taken form the Spanish sample of the European Community HouseholdPanel Survey to estimate a labour supply model for single men and women and to calculate the effects on individual and social welfare caused by the recent IncomeTax reform, in force since 1999. The results of the estimation show that while salary exerts a positive effect on the number of hours offered, non-salary income,as expected, has an negative influence only in the case of women. In relation to their recent Income Tax reform we conclude that, on average, it has meant an increase in the individual well-being of the group examined.
