This guide addresses the complex relationship between unemployment and the various phases of a business cycle. Typically, unemployment peaks during the early recovery phase and diminishes as we approach the cycle’s peak. But the underlying reasons for unemployment extend beyond these cyclical variations.

We can categorize unemployment into three primary types: frictional, structural, and cyclical—each with distinct causes and implications. We aim to clarify these different types of unemployment and measures, providing deeper insight into the underlying dynamics.

Types of Unemployment

1. Frictional Unemployment

Frictional unemployment refers to the temporary period when workers transition between jobs. It occurs naturally as employees seek better employment opportunities and employers look for suitable candidates. This type of unemployment reflects the time required for job seekers and employers to find the right match, emphasizing that job hunting and recruitment are time-consuming.

Seasonal Unemployment

A notable subtype of frictional unemployment is seasonal unemployment, which arises in professions heavily dependent on seasonal conditions. Ski instructors or fishermen, for example, typically face periods without employment due to the seasonal nature of their industries.

2. Structural Unemployment

Among different types of unemployment includes structural unemployment, which occurs when job seekers’ skills do not align with the requirements of available jobs. This mismatch typically results from fundamental economic shifts, such as technological advancements or industrial restructuring. Because technological innovations often lead to significant changes in job markets, structural unemployment is sometimes called “technological unemployment.”

The Role of AI

Major corporations are increasingly investing in artificial intelligence (AI) and machine learning—substantially improving productivity but also increasing structural unemployment risks. Many employees must adapt by acquiring new skills or qualifications, possibly changing careers entirely. For example, AI advancements threaten to significantly reduce employment opportunities in call centers over the next 5 to 10 years, leaving many current employees needing to pursue new careers.

3. Cyclical Unemployment

Unlike frictional and structural unemployment—two of the different types of unemployment—cyclical unemployment is directly related to the fluctuations in economic activity throughout the business cycle phases. During economic peaks, cyclical unemployment rates are typically low because business activity is robust and companies operate at maximum production capacity, demanding a large workforce.

But an overheated economy at peak production levels often triggers inflation. Employees may request wage increases anticipating continued price rises—creating an inflationary wage-price spiral. Central banks may then intervene to cool the economy, reducing business activity and increasing cyclical unemployment, particularly during economic downturns or low points.

Cyclical Unemployment and Full-Employment Goals

While frictional and structural unemployment rates remain consistently positive, cyclical unemployment rates fluctuate, becoming positive or negative depending on economic conditions. When the economy’s output exceeds its potential GDP, resources are overly utilized, resulting in negative cyclical unemployment. Conversely, resource underutilization occurs when economic output falls below potential GDP, making cyclical unemployment positive.

Given the different types of unemployment, countries aim to operate at full-employment GDP, where cyclical unemployment is zero and inflation remains stable. But structural and frictional unemployment persists even at full employment—typically resulting in a total unemployment rate of approximately 4 to 6%. This “natural level” of unemployment fosters healthy economic competition and stimulates continuous improvement across industries, businesses, and workers.

Measuring Unemployment

Defining Unemployment

To accurately measure unemployment, it’s essential to define what constitutes “unemployment” economically. In macroeconomics, simply not having a job does not automatically classify someone as unemployed. Individuals must actively seek work and be available for employment. People who are hospitalized, in the military, full-time students, or not actively searching for work (voluntarily unemployed) are not considered unemployed.

Unemployment Rate

The unemployment rate is calculated as the ratio of unemployed individuals to the total labor force in a country. The labor force includes the currently employed and those unemployed but actively seeking employment—spanning the different types of unemployment.

Voluntarily unemployed individuals and those unavailable for work do not contribute to the unemployment rate—though they influence the activity or participation rate, which measures the labor force as a percentage of the total working-age population.

Discouraged Workers

Discouraged workers have given up seeking employment due to prolonged unsuccessful job searches. Although they’re of working age, their lack of active job searching excludes them from unemployment statistics. The number of discouraged workers typically increases during economic downturns.

Underemployed Workers

Underemployment occurs when highly skilled workers accept low-paying, low-skilled positions due to a lack of suitable opportunities in the job market. For instance, a qualified accountant working as a supermarket cashier would be considered underemployed.

Measuring underemployment is challenging—partly because people sometimes choose lower-paying jobs voluntarily to achieve a better work-life balance. Underemployment should be considered when evaluating the gap between current economic conditions and full-employment GDP.

Calculating the Unemployment Rate

To measure unemployment accurately, we first determine the labor force size. This involves subtracting voluntarily unemployed people, discouraged workers, and individuals unavailable for work from the working-age population (typically ages 16 to 65). This refined labor force figure helps in analyzing the different types of unemployment. Dividing the resulting labor force number by the working-age population gives the participation rate.

Next, the number of unemployed people is found by subtracting employed individuals from the total labor force. Dividing the number of unemployed by the total labor force yields the unemployment rate.

Importance of Understanding Different Types of Unemployment

Understanding the different types of unemployment and their measurements is crucial for evaluating a country’s economic health. Recognizing the distinctions between frictional, structural, and cyclical unemployment allows policymakers and economists to develop targeted solutions that enhance labor market efficiency, improve economic stability, and foster sustainable economic growth.
