In a recent study made by the NBER (National Bureau of Echonomic Research) and commented recently on Slate, it is shown that

there is a negative relationship between real GDP per capita and the female-male difference in total work time per day — the sum of work for pay and work at home.

Some results commented on Slate are quite interesting and positive : women and men do work on average the same in rich countries, which somehow shows a positive balance between genders.

On the other hand, the article has another reading. It states that on average men work less than women in poor countries. I would be very curious to see the relationship between the difference of work time between men and women, on the one hand, and the wealth of the country on the other hand.

Is there a correlation? Is it so that a country “gets richer” when men work more?

Lovely potential for politically incorrect stuff.
