Working hours in the European periphery: The length of the working day in Spain, 1885 -1920

This paper studies the decline of the working day in Spain from 1885 to 1920. The decline was more continuous than previously thought. Differences in hours reinforce wage differentials, showing labor markets were not well integrated. Cross-sectional and time-series analysis suggests that hour reductions reflect a labor supply rather than a labor demand effect. Given the comparatively slow growth of real wages in Spain from 1870 to 1920, the Spanish case shows that international convergence in hours of work must have been stronger than convergence in wages.
