Check all that apply. A lower price level makes domestically produced goods less expensive than foreign goods. A higher price level decreases the real value of consumers' assets. A lower price level increases consumption through the income effect. As the aggregate price level rises, the cost of borrowing money will the quantity of output demanded to effect. causing This phenomenon is known as the

✔ 2 Aplia Assignment Ch 20 4. Determinants of aggregate supply The following graph shows a decrease in short-ron aggregate supply (AS) in a hypothetical economy where the currency is the dollar Specifically, the short-un aggregate supply curve shifts to the left from AS, to AS, causing the quantity of output supplied at a price level of 100 to fall from $200 billion to $150 billion K 1 1 **### PRICE LEVEL 200 20 QUANTITY OF OUTPUT 380 400 The following table lists several determinants of short-run aggregate supply. Regulations on the firm Tax rates Input prices Complete the table by selecting the changes in each scenario necessary to decrease short-run aggregate supply Change Necessary to Decrease AS Grade It Now Save & Continue Continue without saving
1. In the following table, determine how each event likely effects potential output (a.k.a., long-run aggregate supply). Direction of Potential Output Shift Event Left Right No Shift The government allows more immigration of working-age adults. For environmental and safety reasons, the government requires that the country’s nuclear power plants be permanently shut down. An investment tax credit increases the rate at which firms acquire machinery and equipment. 2. In the following table, determine how each event affects the position of the aggregate demand curve. Direction of AD Curve Shift Event Left Right No Shift A decrease in consumer confidence (suggests people believe a contraction/recession coming) A decrease in individual income tax rates An increase in the value/price of housing 3.

1. Let us say the estimated equation for the economy's aggregate demand is Y=400 – 15P+ 8G And the estimated equation for the economy's aggregate supply is Y=5+11P-10W where Y is the country's real GDP, P is the price level (GDP deflator), G is government purchases of goods and services, and W is the index of wages. a. If G= 160 and W= 100, find the equilibrium real GDP and the price level in the economy. b. What is the simple multiplier in this economy? Give the number and explain how you figured it out. c. What is the inflation rate due to the government increasing its purchases from G=160 to G= 180 (expansionary fiscal policy), in %? d. What is the value of the multiplier when the price level varies? 2. Imagine an economy in which the slope of the AD curve is equal to the (negative of) slope of the AS curve. If the simple multiplier is equal to 5, what is the value of the multiplier when the price level varies? Give the number and explain how you figured it out.
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 of 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, the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will , and firms that rely on catalogs v will respond by v the quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected…

Suppose that the aggregate demand and aggregate supply schedules for a hypothetical economy are as shown below: a. Use these sets of data to graph the aggregate demand and aggregate supply curves. What is the equilibrium price level and the equilibrium level of real output in this hypothetical economy? Is the equilibrium real output also necessarily the full-employment real output? Explain.b. Why will a price level of 150 not be an equilibrium price level in this economy? Why not 250?c. Suppose that buyers desire to purchase $200 billion of extra real output at each price level. Sketch in the new aggregate demand curve as AD1. What factors might cause this change in aggregate demand? What is the new equilibrium price level and level of real output?
