Does Raising the Minimum Wage Cause Unemployment?

Raising the minimum wage can cause some job loss, but decades of research show the effect is usually much smaller than basic economic theory predicts, and in some conditions it disappears entirely. Whether raising the minimum wage causes unemployment depends on how large the increase is, how quickly it phases in, and what the local labor market looks like before the change. The federal minimum has sat at $7.25 per hour since 2009, and the Congressional Budget Office’s most recent modeling of a jump to $15 estimates roughly 1.0 to 1.4 million fewer jobs alongside hundreds of thousands of people lifted out of poverty.¹²

What Thirty Years of Studies Actually Show

The modern debate started in 1993, when economists David Card and Alan Krueger surveyed 410 fast-food restaurants on both sides of the New Jersey–Pennsylvania border after New Jersey raised its minimum wage from $4.25 to $5.05. Employment in New Jersey did not fall relative to Pennsylvania.³ The result was controversial and set off a generation of follow-up work.

The biggest of those follow-ups came in 2019, when Cengiz, Dube, Lindner, and Zipperer examined 138 state-level minimum wage increases. Their conclusion: the overall number of low-wage jobs remained essentially unchanged over the five years following each increase. The estimated change was statistically indistinguishable from zero. They did find some reduced employment in sectors exposed to international trade competition, where employers can’t easily raise prices to offset higher labor costs.⁴

The CBO has modeled the federal picture more than once. Its 2021 analysis of the Raise the Wage Act projected 1.4 million fewer jobs in an average week once a $15 minimum was fully phased in, with 0.9 million people lifted above the poverty line.² A 2019 analysis put the number at 1.3 million jobs lost against 1.3 million fewer people in poverty.⁵ More recent modeling of the Raise the Wage Act of 2023 projects about 1.0 million fewer jobs by 2033 under a phased increase to $17.⁶ The CBO’s own ranges for each scenario include the possibility of near-zero job losses at the low end.

Why the Predicted Losses Often Don’t Show Up

The textbook argument is that if labor gets more expensive, employers buy less of it. That model assumes businesses are already paying workers exactly what competition demands. In practice, many low-wage labor markets are dominated by a handful of large employers who have enough market power to keep wages below what open competition would produce. Economists call this monopsony. When a wage floor pushes pay up in that kind of market, it can draw more people into the workforce without forcing employers past their breaking point, because the old wage was artificially low to begin with.

UC Berkeley researchers studying counties that raised their minimum wage to $15 found that in tight post-pandemic labor markets, the increases boosted fast-food employment by about 7.3%, with a positive employment elasticity of +0.08. They attributed the result to monopsony dynamics: reduced turnover meant employers spent less on constant hiring and held on to more experienced workers.⁷

That turnover point matters. Recruiting, screening, and training a replacement for a low-wage position can cost thousands of dollars. When a higher wage convinces workers to stay, the business recoups a real share of the added payroll through lower turnover costs and steadier service. Paying above the bare minimum can be cheaper than constantly backfilling departures.

Prices carry some of the load, too. A Princeton study of restaurant pricing across multiple minimum wage increases found a price elasticity of about 0.2: a 10% wage increase produced roughly a 2% menu price bump.⁸ A $10 meal becomes $10.20. Spread across thousands of transactions, small increases like that cover a meaningful share of the higher wage bill.

The Adjustment That Hides in the Data: Hours, Not Layoffs

Even when head counts stay stable, employers often trim weekly hours to keep total payroll manageable. A worker whose schedule drops from 40 to 35 hours a week doesn’t show up in any unemployment statistic. They still have a job. It’s just a smaller one.

A University of Washington study of Seattle’s minimum wage increases found no change in the probability that an individual worker stayed employed, but it documented significant reductions in hours, especially for less experienced workers. The researchers measured aggregate employment elasticities ranging from −0.2 to −2.0, concentrated on hours rather than headcount in the short run.⁹

European data tells a similar story. An IZA Institute of Labor Economics study found that a 10% minimum wage increase produced roughly a one-hour-per-week reduction in hours for affected workers. The cuts were uneven: workers in food service and manufacturing lost 2.5 to 3 hours per week, while women showed no statistically significant reduction at all.¹⁰

So when you read that a wage increase caused “no job losses,” check what the study measured. The jobs may still be there while the paychecks got smaller.

Which Industries Feel It Most

The impact varies enormously by sector, and treating the whole economy as one lump is where most casual arguments go wrong.

Restaurants and small retail sit at the vulnerable end. Profit margins in independent dining and small retail often run in the low single digits, leaving little room to absorb payroll increases. These businesses also employ the highest concentration of minimum-wage workers, so a raise affects a large share of their workforce at once. Self-order kiosks now cost as little as $2,500 to $7,500 per unit, a one-time expense that replaces recurring hourly wages. Once the annual cost of a human cashier exceeds the annualized cost of the machine, the math tips toward the machine.

Healthcare goes the other way. A federal study of nursing homes found that states with higher minimum wages actually showed slightly more nursing assistant hours per resident, not fewer.¹¹ Nursing homes face state-mandated minimum staffing ratios, so cutting hours is largely infeasible regardless of cost pressure. Raising the federal floor to $15 would affect 76% of nursing assistants nationally and add an estimated $2.5 billion in annual labor costs industry-wide, but the jobs themselves are hard to eliminate when regulations require a minimum number of staff on every shift.

Industries exposed to international competition face a different pressure. If a manufacturer can shift production to a lower-wage country, a domestic wage increase can accelerate that decision. The Cengiz research specifically flagged tradable sectors as the one area with clear evidence of reduced employment after wage increases.⁴ A local diner can’t move to Vietnam. A garment factory can.

Why the Size and Speed of the Increase Matter More Than the Increase Itself

A 5% bump and a 50% jump do not produce proportional effects. They produce qualitatively different outcomes. Small, predictable, phased increases give businesses time to adjust through natural attrition, modest price increases, and efficiency gains. Large, sudden jumps leave less room for gradual adaptation and are more likely to trigger the layoffs and hours cuts the textbook model predicts.

The current federal minimum of $7.25 has not changed since 2009, so any move to $15 represents a doubling of the wage floor.¹ That is an unusually large jump by historical standards, which is why CBO projections for $15 consistently show meaningful employment effects. A more modest increase, phased in over several years with automatic adjustments for inflation afterward, would almost certainly produce smaller disruptions. That’s how most states and cities that have raised wages above the federal floor have structured their increases, and it’s one reason many real-world studies find minimal employment effects.

The CBO has modeled smaller increases alongside the $15 scenario. Its 2019 analysis estimated that raising the federal minimum to $10 per hour would produce essentially zero median job losses, while a $12 floor would produce far more modest effects than the $15 option.⁵ The relationship between the size of the increase and the size of the employment effect is not linear. It accelerates as the wage floor climbs further above what the local economy can absorb.

The Honest Answer

Minimum wage increases produce trade-offs, not catastrophes. Modest, phased increases in most labor markets produce minimal detectable job losses, real income gains for low-wage workers, and small price increases that consumers largely absorb without noticing. Large, sudden increases produce larger disruptions, concentrated in low-margin industries, trade-exposed sectors, and among the least experienced workers. Some of the adjustment shows up as reduced hours rather than lost jobs, which means the true cost to workers can be understated by employment figures alone. Whatever the size of the increase, the job losses are consistently smaller than what the simplest economic models predict.
