Denmark, on the other hand, moved from a 40-hour to a 37-hour week in 1992 and it has been a success. It had no measurable effect on output, and does not seem to have impacted wage or employment growth. Maybe the length of the workweek is not the main problem with France's labor market?
But Denmark, like many Northern European countries is an economy with high tax rates and high redistribution, which can compensate for the lack of growth of labor wages. The US is not a market like that at all.
