Can raising the minimum wage actually boost employment in certain markets?
In short: The debate over minimum wage often centers on whether higher pay kills jobs. While traditional supply and demand models suggest a trade-off, new research into concentrated labor markets reveals a surprising counter-intuitive possibility: that wage hikes might actually increase employment.
In a standard labor market, wages are determined by the interaction of supply and demand, influenced by your specific skill set and the competition around you. However, real-world markets are rarely pure. They are often shaped by regulations like the minimum wage and by the presence of 'monopsony power'—a condition where a few powerful employers dominate hiring and can pay workers less than the value they contribute to the company's bottom line.
A recent study published in the Review of Economic Studies, coauthored by Dr. Ioana Marinescu of the University of Pennsylvania, explores how this market structure changes the impact of wage laws. Using country-wide metrics for labour market density, Marinescu investigated the low-paid retail industry in collaboration with researchers Till von Wachter, Bledi Taska, Emiliano Huet-Vaughn, and José Azar. This concentration measures how much competition exists for workers; high concentration means a small number of firms hold the most power.
The findings suggest that the effect of a minimum wage increase depends heavily on how much control employers have. In markets that are highly concentrated—where a few companies dominate—or in areas with lower population density, increasing the minimum wage can lead to overall positive employment effects. This is particularly evident in sectors like fast food, where employers have significant wage-setting power. Essentially, in less competitive environments where companies have been suppressing wages, there is more room to raise pay without reducing the workforce.
