|January 2019||How Prevalent Is Downward Rigidity in Nominal Wages? Evidence from Payroll Records in Washington State|
with Gary Solon, Jacob L. Vigdor: w25470
For more than 80 years, many macroeconomic analyses have been premised on the assumption that workers’ nominal wage rates cannot be cut. The U.S. evidence on this assumption has been inconclusive because of distortions from reporting error in household surveys. Following a British literature, we reconsider the issue with more accurate wage data from the payroll records of most employers in the State of Washington over the period 2005-2015. For every one of the 40 four-quarters-apart periods for which we observe year-to-year wage changes, we find that at least 20 percent of job stayers experience nominal wage reductions.
|October 2018||Minimum Wage Increases and Individual Employment Trajectories|
with Mark C. Long, Robert Plotnick, Emma van Inwegen, Jacob Vigdor, Hilary Wething: w25182
Using administrative employment data from the state of Washington, we use short-duration longitudinal panels to study the impact of Seattle’s minimum wage ordinance on individuals employed in low-wage jobs immediately before a wage increase. We draw counterfactual observations using nearest-neighbor matching and derive effect estimates by comparing the “treated” cohort to a placebo cohort drawn from earlier data. We attribute significant hourly wage increases and hours reductions to the policy. On net, the minimum wage increase from $9.47 to as much as $13 per hour raised earnings by an average of $8-$12 per week. The entirety of these gains accrued to workers with above-median experience at baseline; less-experienced workers saw no significant change to weekly pay. Approximately one-quar...
|June 2017||Minimum Wage Increases, Wages, and Low-Wage Employment: Evidence from Seattle|
with Mark C. Long, Robert Plotnick, Emma van Inwegen, Jacob Vigdor, Hilary Wething: w23532
This paper evaluates the wage, employment, and hours effects of the first and second phase-in of the Seattle Minimum Wage Ordinance, which raised the minimum wage from $9.47 to as much as $11 in 2015 and to as much as $13 in 2016. Using a variety of methods to analyze employment in all sectors paying below a specified real hourly wage rate, we conclude that the second wage increase to $13 reduced hours worked in low-wage jobs by 6-7 percent, while hourly wages in such jobs increased by 3 percent. Consequently, total payroll for such jobs decreased, implying that the Ordinance lowered the amount paid to workers in low-wage jobs by an average of $74 per month per job in 2016. Evidence attributes more modest effects to the first wage increase. We estimate an effect of zero when analyzing e...
