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?
will an increase in productivity affect the aggregate supply curve and the aggregate demand curve?

- During 2015, there was a substantial increase in stock prices, as well as a reduction in the world price of crude oil. How did the stock and oil price changes influence aggregate demand and aggregate supply in the United States? Check all that apply. These two changes would result in a temporary increase in output. The decrease in the world price of crude oil would cause the SRAS curve to shift to the right. The decrease in the world price of crude oil would cause the LRAS curve to shift to the left. The increase in stock prices would cause the AD curve to shift to the right.arrow_forwardFor each of the following scenarios predict how the price level and output will change over time from immediate impact to long-run impact. In each case, consider an economy that was initially producing at its level of potential output. a. The government passes legislation that increases corporate taxes by 25%. b. Economies around the globe are experiencing a time of prosperity and, as a result, demand for U.S. exports increases.arrow_forwardIn the Keynesian model (that is, the short run), what causes recessions?arrow_forward
- Fill in the blank. ALEX: Hi, Becky. I’m intrigued to see how macroeconomics allows us to explain recent economic events such as the Great Recession that affected so many people. But there’s one thing I don’t understand. Was the collapse of the housing bubble the only cause of the recession, or were there other factors as well? BECKY: Hi, Alex. I agree that macroeconomic theory offers an entirely new perspective on how the economy works. To answer your question, the crash of the housing market was a major factor but not the only cause of the Great Recession. The professor mentioned that the __________ (options: financial, fiscal, government) system deteriorated as well, an event that deepened the economic downturn even further. ALEX: I see. So the bursting of the housing bubble caused the initial decline in aggregate demand. Then the financial crisis caused aggregate demand to decline even more. Could you also help me understand how to use the aggregate demand and aggregate supply model…arrow_forwardWhy 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?

- What relationship does the short-run aggregate supply curve represent?arrow_forwardThe government of South Africa responded to the COVID 19 pandemic by implanting a number of short-term measures to save the economy. Using the Aggregate Demand- Aggregate Supply (AD-AS) model can be used to illustrate that by choosing the right combination of measures (policies) it is possible for the economy to grow and ease the distress on the economy. Discuss four demand-side measures that policy makers can implement to expand the economy?arrow_forwardIn the past two decades, the government of Qatar has made significant investments to increase the level of infrastructure and human capital in the country. Suppose the accompanying graph illustrates the aggregate demand (AD), short‑run aggregate supply (SRAS), and long‑run aggregate supply (LRAS) curves for Qatar before these investments were made. Assume all three curves were impacted by these investments. Adjust the graph to show Qatar’s new long‑run macroeconomic equilibrium.arrow_forward
- Assume that the long-run aggregate supply curve is vertical at Y = 3.000 while the short-run aggregate supply curve is horizontal at P=1.0, . The aggregate demand curve is Y = 2(M / P) and M = 1,500. a. If the is initially in long-run equilibrium, what are the values of P and Y? Draw the equilibrium using AD and short and long run AS curves.arrow_forwardUsing the aggregate supply–aggregate demand model, explain how output and prices are determined.
