What do unions do? The AFL-CIO argues that unions offer a pathway to higher wages and prosperity for the middle class. Critics point to the collapse of many highly unionized domestic industries and argue that unions harm the economy. To whom should policymakers listen? What unions do has been studied extensively by economists, and a broad survey of academic studies shows that while unions can sometimes achieve benefits for their members, they harm the overall economy.

Unions function as labor cartels. A labor cartel restricts the number of workers in a company or industry to drive up the remaining workers' wages, just as the Organization of Petroleum Exporting Countries (OPEC) attempts to cut the supply of oil to raise its price. Companies pass on those higher wages to consumers through higher prices, and often they also earn lower profits. Economic research finds that unions benefit their members but hurt consumers generally, and especially workers who are denied job opportunities.

The average union member earns more than the average non-union worker. However, that does not mean that expanding union membership will raise wages: Few workers who join a union today get a pay raise. What explains these apparently contradictory findings? The economy has become more competitive over the past generation. Companies have less power to pass price increases on to consumers without going out of business. Consequently, unions do not negotiate higher wages for many newly organized workers. These days, unions win higher wages for employees only at companies with competitive advantages that allow them to pay higher wages, such as successful research and development (R&D) projects or capital investments.

Unions effectively tax these investments by negotiating higher wages for their members, thus lowering profits. Unionized companies respond to this union tax by reducing investment. Less investment makes unionized companies less competitive.

This, along with the fact that unions function as labor cartels that seek to reduce job opportunities, causes unionized companies to lose jobs. Economists consistently find that unions decrease the number of jobs available in the economy. The vast majority of manufacturing jobs lost over the past three decades have been among union members--non-union manufacturing employment has risen. Research also shows that widespread unionization delays recovery from economic downturns.

Some unions win higher wages for their members, though many do not. But with these higher wages, unions bring less investment, fewer jobs, higher prices, and smaller 401(k) plans for everyone else. On balance, labor cartels harm the economy, and enacting policies designed to force workers into unions will only prolong the recession.
