Dispersion in the Intensive Margin and PP. Notes: The figure plots the logarithm of the standard deviation of hours worked per day across all respondents within a given three-digit occupation × year group and the corresponding share of PP workers for the years 2010–2012. The dispersion in the intensive margin of labor supply is obtained by following Aguiar and Hurst (2007) in cleaning the ATUS and focusing on three-digit SOCs over 3-year groups to increase the sample representativeness. The observations are weighted by the number of respondents in a given occupation × year category. Source: NCS and ATUS 2004–2017.
