The following graph plots aggregate demand (AD2027AD2027) and aggregate supply (AS) for the imaginary country of Cotopaxi in the year 2027.
Suppose the natural level of output in this economy is $6 trillion.
On the following graph, use the green line (triangle symbol) to plot the long-run aggregate supply (LRAS) curve for this economy.
Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B.
The following table presents projections for the unemployment rates that would occur at point A and point B. Consider the potential rate of inflation between 2027 and 2028, depending on whether the economy moves from the initial price level of 102 to the…

- 6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural level output if the actual price level in the economy deviates from the expected price level. Several theories explain how 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 90. Faced with high menu costs, and firms that rely on catalogs the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will will respond by the quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected decrease…arrow_forwardIn 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
- The following graph shows a decrease in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar. 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. Fill in the table by indicating the changes in the determinants necessary to decrease short-run aggregate supply.arrow_forwardUse appropriate graph(s) to explain the effect of each of the following events, if any, on the position of the short- and long-run aggregate supply curves and the aggregate demand curve for a small open economy. a) The country becomes home to thousands of immigrants who significantly increase its labour force. b) The Central Organization of Trade Unions in the country wins a 10 percent increase in money wage rates for low-income workers. c) There is a decrease in the income of the country's major trading partners. d) The country starts to harness geothermal energy, which it puts to use and sells the excess energy to neighbouring states.arrow_forwardThe following graph shows a decrease in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar.

Suppose the accompanying graph illustrates the aggregate demand (AD), short‑run aggregate supply (SRAS), and long‑run aggregate supply (LRAS) curves for Qatar before these investments were made.

- The following graph shows the short-run and long-run aggregate supply curves (SRAS and LRAS) for an economy. Suppose there is a technological improvement that allows firms to reduce their costs of production permanently. Drag one or both of the curves on the graph to illustrate the long-term effects of this change. If you don't believe there will be any long-term effects, leave the curves where they are. 240 LRAS SRAS 200 SRAS 160 LRAS 120 80 40 6 12 18 24 REAL GDP (Trillions of dollars) Assuming aggregate demand is not affected by the technological improvement, the long-run effect of this v supply shock is v in aggregate output and v in the price level.
