One version of Okun’s law specifies a relationship between the change in the unemployment rate and output growth. This column uses US labour market flows data to investigate this relationship between 1990 and 2017. It finds that the net flows between employment and unemployment are sensitive to changes in growth but respond differently to positive and negative changes. This implies that the US Okun relationship is stable but asymmetric, the effect of a change being larger in contractionary periods than in expansionary ones.

Medical advances in the early part of the twentieth century, especially those concerning child-bearing, increased the fraction of women’s lives that could be devoted to the labour market. They account for the threefold increase in the labour force participation of married women with children between 1920 and 1970 in the US.
