The Inequality of Recession

Recessions are dated as if they arrive for everyone at once. A series of papers applies the Modified Sahm Rule separately to the unemployment of different groups and places, and finds that the downturn starts earlier, cuts deeper and lasts longer for some than the official dates suggest.

The Modified Sahm Rule treats the Sahm Rule’s conventions as free parameters and applies one turning-point function to any disaggregated labor-market series. Each paper below asks the same question of a different dimension of inequality: by the standards of real-time recession detection, does the recession begin, peak and end at the same time for everyone?

Headline numbers compare the first group named with the last, averaged over the recessions selected in the tool (by default 1980 through 2007–09; 2020 excluded). Each chapter shows every figure; “Show full analysis” in any chapter opens all tables, robustness checks and decompositions.
