The gender gap in employment hours: do work-hour regulations matter?

Abstract

In all developed countries, women, especially mothers, work fewer paid hours than their spouses. However, the magnitude of the gender gap varies significantly by country, ranging from 2 to 20 hours per week in this study. Using data from the 2002 International Social Survey Programme, this article investigates whether work-hour regulations have a significant effect on household allocation of paid labour and gender work-hour inequality. Two main types of work-hour regulations are examined: standard weekly work hours and the maximum allowable weekly work hours. Results show that households in countries with shorter maximum weekly work hours had less work-hour inequality between spouses, as each additional allowable overtime hour over the standard working week increased the work-hour gap between couples by 20 minutes. These results indicate that couples’ inequality in work hours and gender inequality in labour supply are associated with country-level work-hour regulations.
