Key Concepts

Effects on Price Level, Real GDP, and Employment

When the SRAS curve shifts left as a result of cost-push factors, the economy experiences a higher price level (inflation) and a decrease in real GDP, which reflects a dampening of economic activity. This reduction in output often leads to decreased demand for labor, potentially resulting in higher unemployment. The phenomenon can create stagflation, where inflation and unemployment rise simultaneously despite stagnant or contracting economic output.

Cost-Push Inflation

Cost-push inflation refers to the rise in the overall price level that occurs when the costs of production increase. This can originate from higher costs for wages, raw materials, or energy, forcing producers to charge more for their goods and services. The mark-up of costs onto prices results in inflation even if consumer demand remains unchanged.

Aggregate Demand (AD) Curve

The aggregate demand curve represents the total quantity of goods and services demanded in an economy at different price levels. In the context of cost-push inflation, the AD curve is used in tandem with the supply curve to analyze how changes in production costs impact overall economic activity, even though the primary shift originates on the supply side.

Short-Run Aggregate Supply (SRAS) Curve

The short-run aggregate supply curve shows the relationship between the price level and the quantity of goods and services that firms are willing to produce in the short run. During a cost-push inflation shock, the SRAS curve shifts to the left, indicating that at every price level, a smaller quantity of goods and services is produced due to higher production costs.

Graphical AD-AS Analysis

The AD-AS model graphically depicts the interactions between aggregate demand and short-run aggregate supply. In a cost-push inflation scenario, the SRAS curve shifts leftwards while the AD curve remains unchanged. This shift results in a higher price level and a lower level of real GDP. The graphical approach helps to visually represent how increased production costs lead to reduced output and potential economic stagnation.
