At the recent ACE meetings I attended, a prominent economist (Christopher Pissarides) asserted in one session that he had found that in developed countries (other than Denmark) women work harder in total (in the paid workforce and in the home) than men. It was a claim that interested me so I have been checking it out. At least one prominent NBER study refutes it overall. There are in fact quite a few countries where men work harder – notably the US – where everyone tends to work quite hard. Women do more work in the home but men make up for it in the paid workforce.
Women might feel they have less free time but when they are not working they tend to sleep whereas men watch TV or do other things. This may change the perception that women have less free time.
An interesting observation is that the richer the country the smaller the gap between hours worked by men and women.
Mark Richardson at Oz Conservative cites the Australian evidence – except for women with children aged less than 5 years men work harder. The attached comments to Mark's post contains data sources.
