Real GDP Demanded in billions aggregate demands
Consider the table below for the aggregate supply (AS), and aggregate demand (AD), for goods and services in the United States.
Price Level P
(Y Axis)
Real GDP Demanded in billions (AD) Real GDP Supplied
in billions (AS)
50 16,300 15,100
60 16,200 15,200
70 16,100 15,300
80 16,000 15,400
90 15,900 15,500
100 15,800 15,600
110 15,700 15,700
120 15,600 15,800
130 15,500 15,900
140 15,400 16,000
150 15,300 16,100
160 15,200 16,200
170 15,100 16,300
1. On the grid below, create a graph depicting the U.S. economy using the table above, and plot the AD
and the AS. (Use EXCEL to plot the graph on a separate sheet if possible, but not required. Use titles on the graph, axes, and curves; Use X axis for Real GDP and Y axis for price level.).
2. a. Calculate the slope of the AD curve using data in the table/graph.
b. Calculate the slope of the AS curve using data in the table/graph.
c. Using 3-4 well-written sentences and numerical examples in the table for the each of the following two questions.
(i) Explain why the AD curve has the slope you calculated as a result of the wealth effect.
(ii) Explain why the AS curve has the slope you calculated as a result of the sticky price theory.
3. Using the graph created from the data in the table, determine the short-run equilibrium price level and level of output. Explain using 2-3 well written sentences how this equilibrium point is determined and include the numerical values.
4. From your graph, explain using 2-3 sentences how an increase in real GDP could occur in the economy and give a specific written real world scenario or example. Include the resulting effect on the price level (P) and give the correct terminology that corresponds to this type of price level change.
