Which of the following statements are true? Which are false?...

Which of the following statements are true? Which are false? Explain why the false statements are untrue. a. Short-run aggregate supply curves reflect an inverse relationship between the price level and the level of real output. b. The long-run aggregate supply curve assumes that nominal wages are fixed. c. In the long run, an increase in the price level will result in an increase in nominal wages.

c. In the long run, an increase in the price level will result in an increase in nominal wages.

Key Concepts

Short-run Aggregate Supply

The short-run aggregate supply (SRAS) curve depicts the relationship between the overall price level in the economy and the quantity of output supplied, assuming that some input prices, especially nominal wages, are fixed in the short term. This fixed wage assumption leads to an upward sloping curve where an increase in the price level raises the real profit margins for firms, encouraging higher production.

Long-run Aggregate Supply

The long-run aggregate supply (LRAS) curve reflects the economy’s potential output when all prices, including nominal wages, are fully flexible. It is typically vertical, indicating that in the long run, the level of real output is determined by the factors of production (like technology and resources) and is independent of the price level.

Nominal Wages Adjustment

Nominal wages are the wage rates before adjusting for inflation. In short-run models, nominal wages are often assumed to be sticky or fixed, which means they do not immediately respond to changes in the price level. However, in the long run, these wages adjust to reflect changes in prices, ensuring that real wages stabilize over time.

Price Level

The price level represents the average level of prices of goods and services in an economy. It plays a crucial role in aggregate supply analysis; in the short run, deviations in the price level affect production due to sticky wages, while in the long run, all prices are flexible and the economy’s output is independent of the price level.
