Substantial minimum-wage increases improve low-wage workers’ living standards more than they cause economic harm

What's this about?

People disagree about whether big rises in the lowest legal pay help workers more than they hurt the economy.

The answer may change by place, worker group, and size of the rise.

What supporters say

• Workers who keep their jobs usually earn more money after pay laws rise.
• Most studies find that big job losses do not always follow smaller pay rises.
• Some forecasts show fewer people living in poverty, even when some workers lose jobs.
• Higher pay may help workers stay longer and move into better-paid jobs.

What critics say

• Results from smaller pay rises may not tell us what happens after very large rises.
• Very large rises can cut work hours or jobs for workers with fewer skills.
• Higher prices can take back part of workers’ extra pay.
• This plan may miss the poorest homes, because many adults there have no job.

How to read this

The number of points on each side does not show which side is right; strong proof matters more.

The bottom line

The evidence leans toward big pay rises helping many low-paid workers, but not all of them.

We are not sure they help more than they harm after every very large rise or in every place.

The claim is that substantial minimum-wage increases do more to improve low-paid workers’ living standards than they do to damage the economy. The evidence supports that view in some circumstances, but it does not establish it for every large increase, worker group or local economy.

The case for

The strongest argument is straightforward: workers who keep their jobs generally earn more. Administrative and long-term studies find higher earnings for many low-paid workers after minimum-wage increases, although the gains are uneven because workers differ in their chances of staying employed or moving between jobs. 2

Large average job losses also appear not to be inevitable, at least for the moderate increases most often studied. A major U.S. study found that losses in low-wage jobs near the new wage floor were roughly offset by gains in jobs paying slightly more. Another study of counties along state borders found little harmful effect on restaurant employment. An international review reached a similar, qualified conclusion: average employment effects are usually small, though they become more negative for vulnerable workers and in some larger policy changes. 1

Employers may respond in several ways besides cutting jobs. They can adjust staffing, hours and turnover, and some evidence suggests that higher wages may improve job quality, reduce worker departures and help employees progress to better-paid work. These findings are less certain than the evidence on immediate pay increases, but they suggest that the benefits may extend beyond the first rise in hourly wages. 3

There is also some evidence that the overall effect on poverty can be positive even when some workers lose employment. A Congressional Budget Office projection of a $15 federal minimum wage found substantial earnings gains for many workers and a net reduction in the number of people below the poverty line, while also predicting job losses for some workers and families. That was a model of one particular policy, not proof that every substantial increase would produce the same result. 4

The case against

The main concern is that average results can hide serious losses for particular people. Large increases may reduce hours or employment among vulnerable workers, and some administrative studies find changes in workers’ chances of remaining employed. Research in Seattle reported reduced hours for some low-paid workers, although those findings are disputed and depend partly on how the comparison group and affected workers are defined. 5

Workers also do not receive the full value of a higher legal wage. Businesses often pass part of their higher labor costs on to customers, especially in labor-intensive industries. Higher prices therefore erode some of the nominal gain and can affect demand and employment. The evidence clearly shows this erosion, but it does not settle whether living standards overall rise or fall after all effects are combined. 6

The minimum wage is also a blunt anti-poverty tool. Many workers who benefit live in families that are not poor, while some poor families have no covered worker at all. Comparisons with the Earned Income Tax Credit find that the tax credit is more closely aimed at low-income working families. That does not prove minimum-wage increases make people poorer, but it weakens the idea that gains for covered workers automatically improve the position of poor households generally. 7

Most importantly, the best evidence may not apply to the very largest increases. Research is strongest for moderate changes, while studies find more negative effects for larger increases and vulnerable groups. Effects may grow unevenly as policies become more ambitious, and local wages, employer power and labor-market conditions matter. 8

The bottom line

The evidence favours a qualified version of the claim, but only with moderate confidence about very large increases. It is well supported that affected workers who remain employed usually gain income, and that large average job losses are not inevitable within the range most studied.

But the evidence is weaker on the complete welfare balance for increases at the upper end of “substantial.” Some workers may lose hours or jobs, prices may absorb part of the gain, and the policy does not reliably reach the poorest households. The most defensible conclusion is conditional: increases matched to local wages and labor-market conditions have the strongest case. Claims that extreme increases will improve living standards overall require more evidence about hours, business contraction, prices and household-level effects.
