Specifically, the short-run aggregate supply curve shifts to the left from AS 1 to AS 2 , causing the quantity of output supplied at a price level of 100 to fall from $200 billion to $150 billion. The following table lists several determinants of short-run aggregate supply.

- In the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from the expected price level in the economy. A number of theories explain reasons why this might happen. For example, the sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. Suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. The actual price level turns out to be 110. Faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will and firms that rely on catalogs will respond by the quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected increase in the price level causes the quantity of output…arrow_forwardThis graph shows an increase in aggregate supply in a hypothetical economy where the currency is the dollar.

The economic prosperity abroad will cause the unemployment rate to the natural rate of unemployment in the short run.

- This graph shows the short-run aggregate supply curve (SRAS) of a hypothetical economy where the currency is the dollar. Last year, the economy was producing at point A. The price level was 145 and the quantity of real GDP supplied was $500 billion. This year, the economy is producing at point B. The price level has fallen to 135 and the quantity of real GDP supplied has fallen to $300 billion and nominal wages were constant as the price level changed. Government officials are confused about why the quantity of output moved from point A to point B, and they ask you for help.

Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from the expected price level in the economy. A number of theories explain reasons why this might happen. For example, the misperceptions theory asserts that changes in the price level can temporarily mislead firms about what is happening to their output prices. Consider a soybean farmer who expects a price level of 100 in the coming year. If the actual price level turns out to be 90, soybean prices will and if the farmer mistakenly assumes that the price of soybeans declined relative to other prices of goods and services, the quantity of soybeans supplied. If other producers in this economy mistake changes in the price level for changes in their relative prices, the unexpected decrease in the price level causes the quantity of output supplied to level of output in the short run. she…arrow_forward
