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?
Suppose that an economy wants to boost available labor hours in order to increase aggregate supply. What is the best way to accomplish this?
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?

- In 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. True Falsearrow_forwardSuppose that the U.S. economy is at full employment when strong economic growth in Asia increases the demand for U.S.-produced goods and services.

How might the economy increase production of exports to meet this demand, given that the economy is already at full employment?arrow_forwardDiscuss about the three time horizons and what is the difference between the immediate short-run (ISR) and the short-run (SR) aggregate supply? a) In the immediate short run (IMR), ( input, output, both input & output ) prices are fixed, and the aggregate supply curve is ( upward sloping, downward sloping, horizontal , vertical ), and firms collectively supply exactly the level of output demanded at any given price level. b) In the short run (SR), ( input, output, both input & output ) prices are fixed or nearly fixed, and the aggregate supply curve is ( upward sloping, downward sloping, horizontal , vertical ) This is because nominal wages and input prices adjust only slowly to changes in the price level. With this curve, an increase in the price level increases real output and a decrease in the price level reduces real output. c) In the long run, all prices are ( fixed, flexible ) and the aggregate supply curve is ( upward sloping, downward sloping, horizontal, vertical ) at the…arrow_forward
