'''Wage rigidity''' is the failure of wages to adjust to changes in labour market conditions, so that they remain above or below the level that would clear the market. Wage rigidity is a central feature of modern labour markets and a key explanation for involuntary unemployment, since if wages cannot fall when demand declines, the adjustment must occur through quantities, namely employment, rather than through prices.

== Forms and causes ==

Wage rigidity takes several forms. '''Nominal wage rigidity''' means that wages are slow to change in nominal terms, often because contracts fix them for a period. '''Real wage rigidity''' means that wages are slow to adjust to changes in prices or productivity. Rigidity may be downward, preventing wage cuts, or general, slowing adjustment in both directions.

Causes of wage rigidity include several factors. '''Long-term contracts''' and collective bargaining agreements fix wages for specified periods. '''Efficiency wage''' considerations lead firms to pay above market-clearing wages to attract and retain workers, reduce turnover, and motivate effort. '''Insider-outsider''' dynamics give incumbent workers the power to resist wage cuts that would benefit unemployed outsiders. '''Minimum wage laws''' and social norms set floors. '''Menu costs''' and '''coordination problems''' make it costly or difficult for firms to adjust wages frequently.

== Efficiency wage theories ==

Efficiency wage theories explain why firms may voluntarily pay more than the market-clearing wage. Higher wages can reduce turnover, since workers are less likely to leave, lowering recruitment and training costs. They can attract more able applicants, improving the quality of the workforce through selection. They can increase effort by making jobs more valuable and by raising the cost of losing them. They can improve morale and reduce shirking, since workers have more to lose.

If all firms pay efficiency wages, the aggregate wage exceeds the market-clearing level, and unemployment results. This provides a micro-founded explanation for involuntary unemployment that does not rely on government intervention or union power, and it helps to explain why unemployment persists even in flexible labour markets.

== Macroeconomic implications ==

Wage rigidity is a central element of Keynesian and New Keynesian macroeconomics. It implies that nominal shocks, such as a decline in aggregate demand or a tightening of monetary policy, have real effects, because wages cannot adjust to restore equilibrium. This provides a rationale for stabilisation policy, since monetary and fiscal measures can offset demand shortfalls and prevent rises in unemployment.

The degree of wage rigidity affects the slope of the Phillips curve and the output cost of disinflation. If wages are very rigid, reducing inflation requires a larger increase in unemployment. Understanding the sources and extent of rigidity is therefore important for calibrating policy and for forecasting the effects of shocks.

== Policy and reform ==

Policies that affect wage rigidity include labour market regulation, minimum wages, collective bargaining arrangements, and social protection. Some degree of rigidity may be desirable, providing insurance for workers and stability for firms, but excessive rigidity can raise unemployment and slow adjustment. Reforms that increase wage flexibility, such as decentralising bargaining or linking pay more closely to productivity, are sometimes recommended, though their effects depend on the specific institutional context.

The design of unemployment insurance and active labour market policies also affects wage adjustment, by influencing the incentives to search and to accept job offers. Balancing insurance against incentives is a central challenge of labour market policy, and the appropriate balance depends on the preferences of society and on the structure of the economy. Understanding wage rigidity is essential for analysing labour market outcomes and for designing policies that support both efficiency and equity.

== Wage rigidity and the business cycle ==

Wage rigidity amplifies business cycles. When demand declines, firms cannot easily cut wages, so they reduce employment instead, causing output to fall further and unemployment to rise. In recoveries, wages may lag, allowing firms to rebuild margins before hiring, which slows the decline in unemployment. These dynamics help to explain the persistence of unemployment and the lag between output recovery and employment recovery.

The degree of wage rigidity varies over the cycle and across countries. In economies with centralised bargaining and strong unions, wages may be rigid across the economy, while in decentralised systems, they adjust more at the firm level. The design of institutions affects the transmission of shocks and the costs of adjustment, and it shapes the trade-off between unemployment and inflation.

== Wage rigidity and inflation ==

Wage rigidity affects inflation dynamics. If wages are slow to adjust, a decline in demand raises unemployment rather than lowering wages and prices, slowing the disinflation process. Conversely, if wages are flexible, a demand expansion may raise wages and prices quickly. The slope of the Phillips curve, which relates inflation to unemployment, depends on the degree of wage and price rigidity.

The interaction between wage rigidity and inflation expectations is important. If workers expect inflation and demand compensation, wage pressures can become self-reinforcing. If expectations are anchored and wage setting is moderate, inflation can remain stable even as the labour market tightens. Understanding these interactions is essential for monetary policy, since the trade-off between inflation and unemployment depends on the structure of wage setting.

== Reforms and institutions ==

Reforms that affect wage rigidity include changes to collective bargaining, minimum wage rules, and employment protection. Their effects depend on the specific institutional context and on the broader policy mix. Some reforms have been associated with improved employment outcomes, while others have increased inequality and insecurity without clear employment gains. The evidence suggests that the design of institutions matters more than their presence or absence, and that reforms should be evaluated on their overall effects rather than on a single dimension.

Social dialogue, involving governments, employers, and workers, can help to design institutions that balance flexibility with protection and that support both employment and productivity. Institutions that encourage wage growth in line with productivity, while allowing adjustment to shocks, tend to deliver better outcomes than either rigid or fully flexible arrangements.
