The imaginary country of Harris Island has the aggregate supply and aggregate demand curves as Table 24.3 shows. Plot the AD/AS diagram. Identify the equilibrium. Would you expect unemployment in this economy to be relatively high or low? Would you expect concern about inflation in this economy to be relatively high or low? Imagine that consumers begin to lose confidence about the state of the economy, and so AD becomes lower by 275 at every price level. Identify the new aggregate equilibrium. How will the shift in AD affect the original output, price level, and employment?
Suppose concerns about the size of the federal budget deficit lead the U.S. Congress to cut all funding for research and development for ten years. Assuming this has an impact on technology growth, what does the AD/AS model predict would be the likely effect on equilibrium GDP and the price level?
If firms become more optimistic about the future of the economy and, at the same time, innovation in 3-D printing makes most workers more productive, what is the combined effect on output, employment, and the price-level?

Chelk all that apply. A higher price level decreases consumption through the substitution effect. A lower price level makes domestically produced goods less expensive than foreign goods.

Suppose the economy of Hawkland is initially at full employment. Currently real GDP is $20 trillion, theprice level is 120, the money wage is $36/hour, the full employment quantity of labor is 300 billionhours per year, and the current unemployment rate is 6%. Draw a fully labeled graph depicting the aggregate goods and services market in Hawkland.Be sure to label all axes and include numerical values for variables on the axes where relevant. Providea brief explanation to the side and show any necessary calculations. Label any relevant curves with azero (0, for example: AD0) and use a zero in a circle to clearly label the initial equilibrium
The economy has shifted and the quantity of the real GDP supplied has increased. What has potentially happened to aggregate price levels? Potentially the price levels have increased to a higher aggregate price level and if the wages are sticky, businesses have hired more employees as labor has become cheaper. O Potentially the price levels have decreased to a lower aggregate price level and if the wages are sticky, businesses have hired more employees as labor has become cheaper. Potentially the price levels have increased to a higher aggregate price level and if the wages are sticky, businesses have fired some employees as labor has become too expensive.
Suppose that a decrease in the demand for goods and services pushes the economy into arecession. In your own words, explain what happens to the price level and real GDP? Explainhow the economy will eventually get back to the potential output?
