Key Concepts

Expectations and Misperceptions

Expectations about future economic conditions and misperceptions regarding relative price changes play a vital role in short-run adjustments. In some theories, firms may temporarily misinterpret changes in the overall price level as changes in the relative price of their products, prompting an increase or decrease in production. As information becomes more accurate, these misperceptions fade, and the market self-corrects, with the speed of adjustment influenced by how rapidly firms update their expectations.

Self-Correcting Mechanisms in the Economy

These are the market forces that drive the economy back toward its long-run equilibrium after a recession or shock without active policy measures. They operate through gradual adjustments in wages, prices, and expectations that eliminate discrepancies between actual output and potential output. The speed of recovery depends on how quickly these adjustments occur.

Price and Wage Rigidity (Sticky Prices/Wages)

Sticky wages and prices mean that, in the short run, nominal adjustments do not occur instantly following an economic shock. This rigidity is crucial in several theories explaining the upward slope of the SRAS, as it causes temporary mismatches between costs and revenues, leading firms to alter production levels until adjustments gradually realign input prices with market conditions.

Short-Run Aggregate Supply (SRAS)

The SRAS curve shows the relationship between the aggregate price level and the total quantity of goods and services that firms are willing to produce in the short run when some input prices, such as wages, are sticky. Its upward slope reflects that higher prices can lead to increased production since wages and other input costs do not immediately adjust, creating temporary profitability advantages for producers.

Long-Run Aggregate Supply (LRAS) and Equilibrium

The LRAS represents the economy's potential output when all prices, including nominal wages, are fully flexible, reflecting factors such as technology and resources. In the long run, the economy tends toward this equilibrium output. Short-run deviations from LRAS are corrected through adjustments in wages, prices, and expectations, eventually restoring full employment without the need for policy intervention.
