Unemployment

Unemployment is the state of being without paid employment or self-employment while being available for work. It is a key indicator of an economy's health. To understand this state, economists use the unemployment rate. This is calculated as the number of unemployed people as a percentage of the labor force. The labor force includes both people who are currently employed and those who are unemployed.

Many complex factors can cause unemployment to rise. The status of the economy is a major driver, especially during a recession. Globalization and international trade can create new competition for local jobs. New technologies and inventions often change the types of work that are needed. Governments and central banks can also influence these numbers. A country might use fiscal policy or monetary policy to change the availability and cost of money. Other causes include market regulation, war, civil disorder, or natural disasters.

Economists categorize unemployment into different types to model its effects. Frictional unemployment is often considered voluntary. This occurs when people make personal decisions about work based on their own values. It includes the time and effort required to find a new job. This type of unemployment is linked to individual search behavior and wage rates. It often involves people deciding to leave one job to find a better one.

Structural unemployment is a different and more persistent type. It happens when there is a mismatch between the skills workers have and the skills employers need. This mismatch is often caused by disruptive technologies or globalization. Because it involves foundational problems in the economy, it is hard to fix with simple stimulus. Training programs are often suggested to help workers gain new skills. This type of unemployment can last much longer than frictional unemployment.

Cyclical unemployment is tied to the business cycle. This is also known as Keynesian unemployment. It occurs when there is not enough aggregate demand in the economy. Aggregate demand is the total demand for goods and services. When demand falls, production decreases and companies need fewer workers. This can create a cycle where macroeconomic forces cause many people to lose jobs. In these cases, the number of unemployed people exceeds the number of available job vacancies.

Classical unemployment, or real-wage unemployment, occurs when wages are set above the market-clearing level. This causes the number of people seeking jobs to exceed the number of vacancies. Some economists argue that minimum wage laws can lead to this. If a law sets a wage higher than the value of a worker's labor, it may increase unemployment. On the other hand, if wages fall below a livable wage, people might stop looking for work. This can happen if public welfare systems provide enough support for families.

There is also a concept called the natural rate of unemployment. This is also known as the NAIRU, or the Non-Accelerating Inflation Rate of Unemployment. It is the rate at which the labor market is in equilibrium. At this rate, there is no pressure for inflation to rise or fall. Some theories suggest that if unemployment gets too low, inflation will accelerate. This is often called the inflation barrier. However, the exact NAIRU is difficult to measure because it changes over time.

Measuring these statistics globally is a massive task. The International Labour Organization (ILO) tracks these figures for the whole world. In 2018, the ILO reported that 172 million people were without work. This represented about 5% of the reported global workforce. Different countries use different methods to find these numbers. Some use surveys, while others look at registered citizens. Because of these different methods, some experts suggest using the employment-to-population ratio instead.
