Sticky wages describe the empirical observation that nominal wages do not adjust freely or quickly in response to shifts in labor supply, demand, or inflation. The phenomenon is especially pronounced on the downside: employers rarely cut nominal pay even when unemployment rises or firms face falling revenues. This downward nominal wage rigidity is a cornerstone assumption in New Keynesian macroeconomics and helps explain why labor markets fail to clear instantly, producing involuntary unemployment during recessions.
Several mechanisms are commonly cited:
- Explicit contracts and collective bargaining agreements that fix wages for months or years.
- Implicit contracts and norms of fairness, articulated in Truman Bewley's interview-based study Why Wages Don't Fall During a Recession (1999), which found managers feared morale damage from pay cuts.
- Efficiency wage theories (Akerlof, Yellen, Shapiro–Stiglitz) suggesting firms pay above market-clearing rates to reduce shirking and turnover.
- Menu costs and coordination failures in revising compensation.
- Minimum wage laws and statutory floors.
John Maynard Keynes emphasized wage stickiness in The General Theory of Employment, Interest and Money (1936), arguing it justified active demand management because labor markets could not self-correct quickly. Later research, including work by economists at the Federal Reserve Bank of San Francisco using CPS microdata, has documented substantial bunching of wage changes at zero, especially during the 2008–2009 recession.
Sticky wages have policy implications relevant to delegates and researchers. Central banks often cite low but positive inflation targets (commonly 2%) partly to "grease the wheels" of the labor market, allowing real wages to fall via inflation when nominal cuts are infeasible. In international contexts, wage rigidity contributed to debates over internal devaluation in Eurozone crisis countries such as Greece, Spain, and Portugal after 2010, where the inability to depreciate a national currency forced painful adjustments through unemployment rather than wage reductions.
Example
During the 2008–2009 financial crisis, U.S. firms overwhelmingly responded to falling demand through layoffs and hiring freezes rather than across-the-board nominal pay cuts, illustrating sticky wages in practice.
Frequently asked questions
Surveys, notably Truman Bewley's 1999 study, find managers worry that nominal pay cuts devastate morale and productivity more than equivalent layoffs, so firms prefer workforce reductions or hiring freezes.
