We quantify firms’ regulation compliance costs from 2002 to 2014 in terms of their labor input expenditure to comply with government rules. Detailed establishment-level occupation data, in combination with occupation-specific task information, allow us to recover the share of an establishment’s wage bill owing to employees engaged in regulatory compliance. Regulatory costs account, on average, for 1.34% of the total wage bill of a firm but vary substantially across and within industries and have increased over time. We investigate the returns to scale in regulatory compliance and find an inverted-U shape, with the percentage of regulatory spending peaking for an establishment size of around 500 employees.
