Wage Stiffness: Reasons, Consequences, and Influence on Business Cycles
The Sticky Wage Conundrum
Wage rigidity is a phenomenon where wages in the labor market don't adjust swiftly in response to changes in supply and demand — even when the unemployment rate skyrockets or drops significantly. Let's unpack why this happens and its consequences for businesses and the economy.
Imagine a company struggling during a recession. Ideally, they'd cut wages to survive, but they face an uphill battle due to various factors. These hurdles create wage rigidity, forcing companies to endure higher operating costs and reduced profitability.
Wage Adjustments in Difficult Times
During a recession, the labor market typically experiences oversupply — meaning there's more workers available than there are job openings. In this situation, wages should logically decrease to support profits. But due to wage rigidity, companies can't Lower wages, leading to a hit on their profits.
Take a case where a recession lasts two years. If wages were flexible, the company could reduce them by $100 each year to maintain profitability. However, due to wage rigidity, they can't make the necessary cuts, causing their profits to take a $200 hit over the two-year period.
In the recovery phase, businesses might be reluctant to raise wages, even though the demand for labor increases. They often want to compensate for the pent-up wage cut they couldn't make during the recession, leading to relatively slower wage growth during the recovery.
Downward vs. Upward Rigidity
Wage rigidity presents itself in two ways: downward and upward.
Downward rigidity refers to difficulty in lowering wages during challenging times, like a recession. Conversely, upward rigidity means wages don't immediately increase following a labor market improvement.
Glue on Wages
In a perfect supply-demand model, wages should adjust according to the equilibrium in the labor market. However, since 2008, this relationship has been murky — wages aren't responding as expected to changes in supply and demand. As a result, wages tend to be rigid and slow to move down during a recession or slow to rise during the recovery.
Economists have proposed reasons for this, such as employment contracts, minimum wages, and the efficiency wage theory, which we'll delve into subsequently.
When Wages are Flexible
If wages were flexible, they would follow changes in the price level. When inflation spikes, the purchasing power of wages drops, prompting higher wage demands to make up for lost purchasing power. Thus, real wages remain relatively constant in such a scenario.
Similarly, when the price level drops, flexible wages would also decline quickly, introducing excess supply to the labor market, and keeping real wages steady.
Money Neutrality Theory
According to the money neutrality theory, monetary policy changes only affect prices and nominal variables. It posits that these changes don't impact real variables like real wages, unemployment, or output. This means changes in the money supply won't impact the economy significantly.
Labor Market Dynamics During a Business Cycle
Wage rigidity is a constant during the business cycle. During a recession, the economy faces downward wage rigidity, with wages stubbornly staying high despite the declining price level and high unemployment. This leads to decreased demand for labor and more unemployment.
On the other hand, during the recovery, the economy faces upward wage rigidity, preventing businesses from immediately raising wages despite the increasing need for more workers.
Causes of Wage Rigidity
Economists offer several reasons for wage rigidity. We'll explore three key factors: employment contracts, minimum wage, and the efficiency wage theory.
Employment Contracts
Companies often don't revise their contracts to respond to business situations. Contracts usually have a long lifespan, and companies typically avoid reducing nominal wages to avoid demoralizing employees and negatively impacting their productivity. Also, contracts are often indexed to account for inflation, stabilizing real wages. Changes in real wages happen only when a new contract is negotiated due to their lengthy validity.
Minimum Wage
The minimum wage is the lowest payment companies can provide their workers. Firms can't pay workers less than the minimum wage. The minimum wage acts as a price floor and prevents wages from falling when they should. During a recession, job creation falls, and the demand for labor decreases, resulting in increased unemployment. Ideally, the market wage should fall to be consistent with the market situation. However, the minimum wage prevents that from happening, leading to an excess supply of labor.
Efficiency Wage Theory
The efficiency wage theory suggests that labor productivity depends on the wages given. If wages are higher, workers become more productive, and vice versa. Firms prefer to pay higher wages to realize higher productivity from their workers. This explains why firms might not lower wages during a recession — doing so would lead to lower productivity, a higher cost per unit, and depressed profit margins.
