A production possibilities curve (PPC) represents the maximum amount of two goods or services produced by manufacturers in an economy.
How are the PPC and long-run aggregate supply curve similar?
Suppose that an economy wants to boost available labor hours in order to increase aggregate supply. What is the best way to accomplish this?
Why does the short-run aggregate supply curve slope upward to the right? If the prices of both (a) resources and (b) goods and services increased proportionally (by the same percentage), would business firms be willing to expand output? Why or why not?

- what impact would a change that shift an economys production possibilities curve outward have on the long run aggregate supply curve?arrow_forwardWhen does macroeconomic equilibrium occur? Multiple Choice When exports equal imports. When the aggregate supply equals the long-run Aggregate Supply When the aggregate demand equals the long-run Aggregate Supply. When the aggregate quantity demanded is equal to the aggregate quantity supplied.arrow_forwardAs you know, supply and demand shifts are caused by one of their determinants. Shifts in aggregate demand (AD) show the effect of events on price level and Real GDP. Any event that causes a change in consumer, business, or government spending or any change in net exports (C+l+G+Xn) will shift AD. Any event that causes a change in production costs or increases productivity will shift aggregate supply (AS). Decide if the following events are Micro, shifting supply or demand, or Macro, shifting AD or AS. Give the direction in which the graph shifts.

Show the determination of the economy's long-run macroeconomic equilibrium by (i) using the Line tool to draw and label the long-run aggregate supply curve to show an equilibrium and (ii) using the Point tool to identify the equilibrium point.

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…arrow_forward
- Using the aggregate supply–aggregate demand model, explain how output and prices are determined. Will output vary or stay fixed in the long run? Suppose the aggregate demand curve were to remain fixed: What can we infer about the behavior of prices over time?arrow_forwardThe graph below is associated with a hypothetical country. Consider an increase in aggregate demand (AD). Specifically, aggregate demand shifts to the right from AD1AD1 to AD2AD2, causing the quantity of output demanded to rise at each price level. For instance, at a price level of 140, output is now $400 billion, where initially it was $300 billion. Fill in the missing values in the table by selecting the change in each scenario required to increase aggregate demand. Change required to increase AD Expected rate of return on investment.

- A5arrow_forwardRecent data from the Bureau of Labor Statistics show that the average price level for consumers rose 5.4% over the past year. While some are expressing concern over rising inflation leading the economy to “overheat,” there is some evidence indicating that this is due to the reopening of the economy as producers adjust to rising demand for goods and services. Many of the goods with the largest price increases, like bacon or cars and trucks, cannot have their production ramped up as quickly as demand is increasing. Other industries are facing supply chain challenges, like shortages of truck drivers. These problems are most likely to be short term, so, as supply catches up with demand, we can expect to see prices return to normal. As evidence, after spiking to record highs in early summer, lumber prices have now fallen below their price at the start of the year. The reason for the dramatic price increase earlier in the year was a combination of reduced supply in 2019 and a surge in demand…arrow_forwardIn the long-run, aggregate supply is a horizontal line at the long-run price level people can afford. True False One reason for why the aggregate demand curve slopes down is the wealth effect, which means that a higher price level leads to lower real wealth and, thereby, reduces the level of consumption.
