Inflation and Unemployment: Causes and Effects
Inflation and Unemployment: A Deep Dive
Understanding Unemployment
Unemployment occurs when individuals are actively seeking work but cannot find employment. The unemployment rate represents the percentage of unemployed workers within the total labor force. There are two primary types of unemployment:
- Voluntary Unemployment: Occurs when a worker declines a job because the offered wage is deemed too low.
- Involuntary Unemployment: Arises due to external factors, such as union influence or government regulations, that hinder wage adjustments.
Neoclassical economists explain persistent involuntary unemployment through two main factors:
- Frictional Unemployment: This happens because some workers are always transitioning between jobs, taking time to find a better fit.
- Structural Unemployment: This results from mismatches between the location and skills of available workers and those demanded by employers. Companies may invest in areas lacking a suitable workforce, or jobs may require specialized skills that are difficult for workers to acquire.
Even under favorable economic conditions and full employment, a certain level of unemployment, known as the natural rate of unemployment, will always exist.
Neoclassical economists traditionally assumed wage flexibility (upward and downward adjustments to reach equilibrium). In contrast, Keynesian economists believe wages are inflexible downward, meaning the labor market adjusts through the number of employed workers rather than price (wages).
Unemployment and Economic Growth
Okun’s Law describes the relationship between the rate of output growth (GDP) and the unemployment rate. Increased output growth generally leads to an increase in employed workers. Understanding this relationship helps determine the economic growth needed to reduce unemployment. For example, some statistical models for Argentina suggest a 3% economic growth is required to reduce the unemployment rate by 1%.
Unemployment and Inflation: The Phillips Curve
The Phillips Curve suggests an inverse relationship between unemployment and inflation: higher unemployment typically corresponds to lower inflation, and vice versa. High unemployment often indicates an economic recession, leading to lower prices (deflation). Conversely, full employment can increase aggregate demand. If production cannot keep pace with this demand, prices generally rise, resulting in inflation.
While this relationship is common, exceptions exist, such as stagflation, where both high unemployment and high inflation occur simultaneously.
Deflation and Inflation
- Deflation: Characterized by a decline in prices, often associated with unemployment and economic recession due to lack of consumption.
- Inflation: A sustained and widespread increase in prices.
Problems Caused by Inflation
- Lack of Price Transparency: Prices rise disproportionately and at different times, making it difficult to know the true cost of goods.
- Currency Devaluation: The value of money decreases over time.
- Wage Deterioration: With the same salary, individuals can purchase fewer goods each month.
- Government Revenue Loss: Taxes are assessed at one point but often paid later, when the value of that money has decreased due to inflation.
Causes of Inflation
- Monetarist Approach (Neoclassical): Attributes inflation primarily to the government printing excessive money. An imbalance between the money supply and the available goods leads to a general increase in prices.
- Structuralist Approach (Keynesian): Argues that inflation is not solely caused by printing money. If both the money supply and the quantity of goods increase proportionally, inflation may not occur. Structuralists emphasize that constraints on production, such as limited capacity in key sectors, can lead to systematic price increases.
Hyperinflation
A specific and extreme case of inflation where prices rise by more than 50% per month.
