Key Economic Models and Categories of Joblessness

Categories of Unemployment

Unemployment is categorized based on its underlying causes, helping economists and policymakers understand labor market dynamics and implement targeted solutions.

Frictional Unemployment

Frictional Unemployment refers to persons seeking employment. This type of joblessness occurs when workers are looking for a job that is most beneficial to them. This includes individuals entering the labor market from school or those who have voluntarily or involuntarily left previous jobs and are currently in transition.

Structural Unemployment

Structural Unemployment refers to persons who have lost their jobs due to fundamental changes in the structure of demand (e.g., industry decline) or the introduction of new technologies (automation).

Seasonal Unemployment

Seasonal Unemployment refers to people who have lost their jobs after a drop in the demand for a specific activity or those engaged only during certain times of the year. Examples include workers in winter construction or ski resort operations.

Residual Unemployment (Paro Residual)

Residual Unemployment (sometimes referred to as Paro Residual) refers to the group of unemployed persons who suffer from physical or mental problems that considerably limit their opportunities to find employment.

Economic Models of Wage Determination and Joblessness

These models attempt to explain phenomena like wage rigidity—why wages do not always fall despite the existence of unemployed workers willing to accept lower pay—and how employment contracts are structured.

The Model of Implicit Contracts

In The Model of Implicit Contracts, employees are considered to have a higher risk aversion than their employers. Therefore, workers prefer to secure employment with stable, albeit lower, wages, rather than accepting high salaries that carry the risk of company closure and job loss.

The Internal Market Model

The Internal Market Model of companies tries to explain why the existence of unemployed workers, theoretically willing to accept employment at any price, does not cause the fall of wages. Key factors include:

• Trust and Reliability: Many jobs require a degree of trust in the employee. Firms often look for internal candidates or acquaintances who have been with the company for some time.
• Specialized Training: Other jobs require highly specialized training, which is often achieved only by staying long-term in the same employment.

The Model of Fair Payment

The Model of Fair Payment focuses on certain behaviors that, although not easily explained rationally, are common in the workplace. This model recognizes that a large group of workers strives more than the company explicitly requires of them, often motivated by a sense of fairness or reciprocity.

The Anti-Shirking Wage Model (Efficiency Wages)

The Anti-Shirking Wage Model (related to the concept of shirking, or avoiding work) posits that a company cannot constantly monitor every worker to ensure maximum performance. The most effective way to encourage high effort and productivity is to offer good salaries—wages above the market clearing rate—making the cost of job loss high for the employee.

The Reverse Selection Model (Adverse Selection)

The Reverse Selection Model emphasizes the fear of employers regarding wage cuts. If wages were to fall every time the company faced a difficult juncture, the first workers to leave would likely be the best performers, as they would feel confident about finding a better-paid job elsewhere. This phenomenon is known as adverse selection.
