Unions do more than raise labor costs of employers with whom they negotiate. They also reduce wages and job growth in states where they are most prevalent. That's the conclusion of a new monograph published by the Washington, D.C.-based Competitive Enterprise Institute titled "The Unintended Consequences of Collective Bargaining" (see pdf). The authors, economist Lowell Gallaway (Ohio University) and law student Jonathan Robe, calculate union-associated "deadweight loss," on a state-by-state basis, over several decades. They concluded that a relatively high proportion of unionization, or union density, correlates with high rates of job loss. This suggests that by forcing employers to the bargaining table, federal labor law depresses entry-level worker prospects. It also suggests that state Right to Work laws mitigate this outcome.
