The following graph plots aggregate demand (AD2027AD2027) and aggregate supply (AS) for the imaginary country of Cotopaxi in the year 2027.
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…
"The demand curves for all products have
negative slopes. For instance, the demand
curves for milk,automobiles, personal
computers, and shirts all have negative
slopes. Therefore, because the aggregate
demand curve shows the demand for all
products, it too must have a negative slope. "
Comment on this assertion.
Considering the formula for Aggregate Demand (Also known as the product market) answer the following question:Name two macroeconomic variables (from this formula) that decline when the economy goes into recession, and explain why this happens?Name one macroeconomic variable (from this formula) that rises during a recession, and explain why this happens?

- Using a macroeconomics demand/supply analysis, where do you think current output is relative to what the economy is capable of producing? Look at recent trends in the data. What are the recent trends in the components of aggregate demand (consumption spending, investment spending, government purchases, and exports and imports?arrow_forwardThe following graph shows a decrease in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the left from AD1AD1 to AD2AD2, causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion. The following table lists several determinants of aggregate demand. Complete the table by indicating the change in each determinant necessary to decrease aggregate demand. Change needed to decrease AD Wealth (increase/ decrease) Taxes (increase/ decrease) Expected rate of return on investment (increase/ decrease) Incomes in other countries (increase/ decrease)arrow_forwardDraw an aggregate demand and supply diagram for Japan.

- What is the shape of a typical Hubbert Curve?arrow_forwardA majority of economists believe that in the long run, real economic variables and nominal economic variables behave independently of one another. For example, an increase in the money supply, a no long-run effect on the quantity of goods and services the economy can produce, a quantity of money will impact the price level but not the output level is known as VERTICAL AXIS However, in the short run, most economists believe that real and nominal variables are intertwined. Economists use the model of aggregate demand and aggregate supply to examine the economy's short-run fluctuations around the long-run output level. The following graph shows an incomplete short-run aggregate demand (AD) and aggregate supply (AS) diagram-it needs appropriate labels for the axes and curves. In the questions that follow you will identify some of the missing labels. The aggregate price level.

- The Federal Reserve Bank of Atlanta releases its monthly Wage Growth Tracker to study trends in wages across various industries. One interesting issue is whether wages rise faster for those who stay in their current jobs (job stayers) or those who seek new opportunities (job switchers). According to the data, job stayers tend to do better than job switchers during a recession. But when the labor market is strong, job switchers experience higher wage growth than job stayers. a. During a recession, job stayers do better than job switchers because a.labor demand increases and job switchers can find jobs with higher wages. b.labor supply decreases and job switchers can find jobs with higher wages. c.labor demand decreases and job switchers cannot find jobs with higher wages. b.
