In an AD/AS Diagram, an Increase in Structural Unemployment Will… Shift the AS Curve to the Left

Structural unemployment, a persistent form of joblessness caused by a mismatch between the skills possessed by workers and the skills demanded by employers, has significant macroeconomic consequences. Understanding its impact requires analyzing its effects within the context of the aggregate demand (AD) and aggregate supply (AS) model. This article will delve into the intricate relationship between structural unemployment and the AD/AS diagram, demonstrating how an increase in structural unemployment will shift the AS curve to the left, leading to a decrease in real GDP and potentially influencing the price level.

Understanding the AD/AS Model

Before exploring the implications of structural unemployment, let's briefly review the fundamentals of the AD/AS model. This macroeconomic model depicts the relationship between the aggregate price level and the aggregate quantity of goods and services produced in an economy.

Aggregate Demand (AD)

The AD curve illustrates the total demand for goods and services in an economy at various price levels. It slopes downwards due to several factors, including:

• Wealth effect: A lower price level increases the real value of consumers' assets, leading to higher consumption.
• Interest rate effect: Lower prices reduce the demand for money, lowering interest rates and stimulating investment.
• Exchange rate effect: Lower prices make domestic goods more attractive to foreign buyers, increasing net exports.

Aggregate Supply (AS)

The AS curve represents the total supply of goods and services in an economy at various price levels. The shape of the AS curve depends on the time horizon considered:

• Short-run aggregate supply (SRAS): This curve is upward-sloping because, in the short run, firms can increase output by increasing production with existing resources, even if it means paying higher wages or input prices.
• Long-run aggregate supply (LRAS): This curve is vertical at the economy's potential output (Y*), representing the sustainable level of output determined by factors such as the size and quality of the labor force, capital stock, and technology.

The Impact of Structural Unemployment on the AS Curve

An increase in structural unemployment directly impacts the economy's productive capacity, thereby shifting the AS curve. This impact occurs primarily through the following mechanisms:

Reduced Labor Force Participation

Structural unemployment signifies a significant portion of the labor force is unemployed due to skill mismatches. These individuals may become discouraged and drop out of the labor force altogether. This decline in the labor force participation rate reduces the available pool of workers, directly impacting the economy's potential output. A smaller workforce translates to a lower level of aggregate supply, shifting the SRAS and LRAS curves to the left.

Decreased Productivity

Even if the labor force participation rate remains unchanged, structural unemployment significantly impacts productivity. When a considerable number of workers lack the necessary skills for available jobs, the overall efficiency of the workforce diminishes. This leads to a reduction in the output that can be produced with the same amount of inputs, directly affecting the aggregate supply. Again, this manifests as a leftward shift of both the SRAS and LRAS curves.

Underutilization of Resources

Structural unemployment results in underutilization of human capital—a key resource in the production process. Skilled workers who are unemployed represent wasted potential output. The economy's productive capacity shrinks, leading to a lower potential GDP and a leftward shift of the LRAS curve. This also affects the SRAS curve as firms operate below their full capacity.

Increased Wage Rigidity (in the short run)

While not a direct cause, increased structural unemployment can exacerbate wage rigidity in some sectors. In industries where demand for specific skills has declined, wages might remain stubbornly high due to union contracts, minimum wage laws, or employer reluctance to reduce wages. This wage rigidity further limits the ability of firms to adjust and increase output in response to changes in demand, contributing to a less responsive SRAS curve and a potential leftward shift in the short run.

The Consequences of the Leftward Shift of the AS Curve

The leftward shift of the AS curve, driven by an increase in structural unemployment, has several negative macroeconomic consequences:

Reduced Real GDP

The most immediate consequence is a decline in real GDP (Y). The economy's potential output decreases, leading to lower overall production of goods and services. This reduction in output can lead to lower economic growth and potentially a recession.

Increased Price Level (Potential)

While a decrease in real GDP is certain, the effect on the price level is more complex and depends on the interplay between the AD and the shifted AS curve. In some cases, the leftward shift of AS can lead to cost-push inflation. Firms, facing a shortage of appropriately skilled workers, may experience increased costs to find and hire suitable employees, leading to higher prices for goods and services. This results in a higher price level, although the overall effect on the price level depends on the relative shifts of AD and AS.

Increased Unemployment (Beyond Structural)

The increased structural unemployment initially triggers the AS shift. However, the resulting decline in aggregate demand due to reduced output and higher prices can lead to further increases in overall unemployment. This creates a ripple effect where structural unemployment contributes to a broader increase in overall unemployment.

Reduced Living Standards

The combined effects of lower real GDP, potentially higher prices, and increased unemployment lead to a decline in overall living standards. Households experience lower incomes, potentially facing higher prices for essential goods and services, leading to decreased purchasing power and a reduced quality of life.

Policy Responses to Address Structural Unemployment

Addressing the macroeconomic consequences of structural unemployment necessitates a multi-pronged policy approach focused on shifting the AS curve back to the right. Policies can include:

Investment in Education and Training

Investing in education and training programs helps equip workers with the skills demanded by the modern economy. This reduces the skills mismatch that fuels structural unemployment, directly increasing the effectiveness of the labor force and shifting the AS curve to the right.

Active Labor Market Policies

These policies aim to actively assist unemployed individuals in finding jobs. This includes job search assistance, career counseling, and retraining programs. These interventions improve the efficiency of the labor market, reducing the time unemployed individuals remain jobless and thus boosting overall potential output.

Infrastructure Development

Investing in infrastructure projects can create jobs and boost economic growth, indirectly reducing unemployment. Improved infrastructure can facilitate greater productivity across various sectors of the economy.

Technological Advancement

Encouraging technological innovation and adoption can lead to increased productivity and the creation of new jobs, counteracting the negative impact of structural unemployment. Innovation often creates new sectors with different skill demands, requiring retraining and education but ultimately boosting the economy's productive capacity.

Deregulation (in Specific Cases)

In certain instances, excessive regulations can hinder job creation and economic growth. Careful deregulation in specific sectors can help stimulate employment and shift the AS curve to the right. However, deregulation must be carefully considered to avoid negative externalities.

Conclusion

An increase in structural unemployment represents a significant macroeconomic challenge, resulting in a leftward shift of the aggregate supply (AS) curve in the AD/AS model. This shift leads to reduced real GDP, potentially increased prices, and higher overall unemployment. Addressing this issue requires a holistic approach that incorporates active labor market policies, investments in education and training, infrastructure development, and technological advancements. By implementing these strategies, governments and policymakers can mitigate the negative economic consequences of structural unemployment and promote a more robust and resilient economy. Understanding the intricate relationship between structural unemployment and the AD/AS model is crucial for developing effective and sustainable economic policies.
