"We examine the distribution of hours of work across industrial sectors in OECD countries. We find large disparities when sectors are divided into three groups: one that produces goods without home substitutes and two others that have home substitutes — health and social work, and all others. We attribute the disparities to the countries' tax and subsidy policies. High taxation substantially reduces hours in sectors that have close home substitutes but less so in other sectors. Health and social care subsidies increase hours in that sector. We compute these effects for nineteen OECD countries."
