Jacob Vigdor on the Seattle Minimum Wage

Episode Summary

Executive Summary: The episode examines Seattle’s $15 minimum wage experiment with economist Jacob Vigdor, focusing on how rigorous quasi-experimental methods can isolate policy effects. Vigdor explains that while hourly wages rose for low-wage workers, hours worked fell, especially for less-experienced workers, reducing opportunities for new entrants. The conversation also explores restaurant industry adaptation, measurement challenges, and the broader debate over whether minimum wage laws help current workers at the expense of future ones.

Main Topics: Seattle’s minimum wage timeline and policy design (Priority: 5/5): Vigdor recounts SeaTac’s first $15 minimum wage, Seattle’s subsequent adoption, and the law’s phased implementation by firm size. Research design and identifying causal effects (Priority: 5/5): The study used Washington State administrative data, border comparisons, synthetic controls, and falsification tests to estimate policy impacts on wages and employment. Employment, hours, and earnings effects (Priority: 5/5): Findings suggest low-wage hourly wages rose, but hours fell more than employment headcount, with the sharpest losses among less-experienced workers and new entrants. Restaurant industry adaptation (Priority: 4/5): Restaurants responded by reorganizing service models, reducing labor intensity, shifting toward counter service, and outsourcing prep work. Distributional and moral debate over minimum wages (Priority: 4/5): The discussion weighs benefits to incumbent low-wage workers against harms to teenagers, inexperienced workers, and people trying to enter the labor market. Media reaction, robustness, and scientific caution (Priority: 3/5): Russ Roberts and Vigdor discuss how results were spun in the media, how specifications were pre-committed, and why long-run effects are harder to measure.

Key Arguments: Seattle’s administrative unemployment-insurance data enabled a stronger analysis because it allowed researchers to compute hourly wages from hours worked and earnings rather than relying only on job counts. Simple border comparisons between Seattle and nearby suburbs failed falsification tests, indicating they were poor control groups because pre-trends differed even before the minimum wage change. Synthetic control methods identified better matches for Seattle in the exurbs and other parts of Washington with similar growth patterns, improving causal inference. The minimum wage appears to have raised hourly wages for low-wage workers by about 3%, but reduced hours worked by roughly 6% to 7%. The negative employment effect is concentrated among less-experienced workers and new entrants, who face fewer opportunities to get their first foothold in the labor market. Many current low-wage workers may break even or gain modestly, while people who would have been hired later bear the larger cost through lost opportunities. Restaurants have many ways to adjust to higher labor costs: changing menus, outsourcing prep, replacing table service with counter ordering, or reducing low-wage tasks. Headcount employment can stay stable even while low-wage hours fall, especially in a growing city where restaurant openings offset labor-saving changes. The policy may speed up labor-saving innovation and automation, which can spread beyond Seattle and reduce low-skill employment more broadly. The minimum wage is not well targeted as an anti-poverty policy because it benefits some low-wage workers while harming others, especially those without experience.

Data Points: SeaTac minimum wage: $15/hour - First $15 minimum wage in the nation, adopted in early 2014 after a ballot initiative. Seattle large-employer minimum wage: $15/hour in 2017 - Phase-in schedule under Seattle’s ordinance for larger firms. Seattle smaller-employer minimum wage: $15/hour in 2019 - Smaller businesses reached the full $15 wage later. Study budget bid: $1.7 million - University of Washington team initially priced the full scope of work for Seattle’s RFP. City budget line item: $100,000 - The mayor’s proposed budget initially listed only $100,000 for the study. Hourly wage effect: about 3% increase - Estimated rise in hourly wages in the low-wage labor market under $19/hour. Hours worked effect: about 6% to 7% decrease - Estimated decline in hours worked after the minimum wage increase. Low-wage threshold: under $19/hour - Operational definition used for the low-wage labor market in the analysis. Alternative threshold tests: $15 to $25, even up to $40 - Robustness checks showed results were similar across different cutoffs. Typical low-wage worker hours: 20 hours/week to 18-19 hours/week - Illustrative example of how the hours reduction might affect a part-time worker. More experienced workers’ earnings change: about $20/week more - Average paycheck gain for more experienced low-wage workers. Low-wage worker full-time share: about 10% - Share of the lowest-wage workers who worked 40 hours consistently for more than six months. Seattle teenagers in population: second lowest in U.S. - Only San Francisco had a lower share of teenagers, according to Vigdor. Minimum wage in Seattle for large employers: $16/hour - Current wage level at the time of the interview for large employers. Years of pre-policy data: about 10 years - Time span used to match Seattle’s pre-treatment trends in synthetic control analysis. Study period: 2005 to 2014 - Pre-policy trend window used to compare Seattle with control regions. Families interviewed: 50 low-income families - Qualitative component of the research included interviews with families relying on low-wage work. Restaurant industry comparison: no negative impact on overall restaurant employment - The study and prior restaurant-focused work found headcount in restaurants was not substantially reduced. Current federal minimum wage: $7.25/hour - Referenced as the lower federal floor in states without higher local minimum wages.

Pivotal Quotes: "the minimum wage is a policy that prices teenagers out of the market" — Russ Roberts: Roberts summarizes his long-held concern about minimum wage policy during the discussion of who benefits and who loses. "we found that wages went up about 3%. As a result of the minimum wage increase, but then hours were down about six or seven percent" — Jacob Vigdor: Vigdor states the core empirical finding from the Seattle study. "the number one skill that you can have if you're a dishwasher is experience being a dishwasher" — Jacob Vigdor: Vigdor explains why employers emphasize prior experience and why higher minimum wages reduce entry-level hiring.

Implications: Seattle’s case suggests minimum wages can raise pay for some incumbents while reducing hours and entry opportunities for the least experienced. For employers, adaptation may mean labor-saving redesign and automation; for policymakers, the big question is whether the gains justify the lost ladder into work.
