- Explain the factors that cause the Aggregate Demand curve to be downward sloping left to right.arrow_forwardThe 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…arrow_forwardUsing 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_forward
- "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.arrow_forwardThe aggregate demand curve portrays the relationship between price level and real GDP. What are the three reasons this relationship is a negative or inverse relationship? Provide brief illustrations of each.arrow_forwardConsidering 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?arrow_forward
- The following events shift either aggregate demand, aggregate supply, both or neither. Using a diagram, illustrate the effect of the events on the economy. In particular, explain the effect of each event on price level, real GDP and equilibrium in the economy. A) A recent business survey reported that business confidence has declined. B) Government cuts the rate of personal income tax after a pandemic caused an economic slowdown. C) A recent flooding in a small rural region destroyed the potato crop. D) A booming economy in a neighbouring country has drawn many working age people (and their families) to emigrate there in search of jobs and better life.arrow_forwardThe following events shift either aggregate demand, aggregate supply, both or neither.

- The following graph shows the short-run and long-run aggregate supply curves (SRAS and LRAS) for an economy. Suppose there is a technological improvement that allows firms to reduce their costs of production permanently. Drag one or both of the curves on the graph to illustrate the long-term effects of this change. If you don't believe there will be any long-term effects, leave the curves where they are. 240 LRAS SRAS 200 SRAS 160 LRAS 120 80 40 6 12 18 24 REAL GDP (Trillions of dollars) Assuming aggregate demand is not affected by the technological improvement, the long-run effect of this v supply shock is v in aggregate output and v in the price level. PRICE LEVELarrow_forwardThe following graph shows an aggregate demand curve (AD) illustrating the inverse relationship between the price level and the quantity of Real GDP in the United States. During World War II, the United States increased military spending. Show the effect of the following scenario on the aggregate demand curve by dragging the curve or moving the point to the appropriate position. Note: Tool tip: To move the curve, click and drag any part of the curve. The curve will snap into position, so if you try to move it and it snaps back to its original position, just try again and drag it a little farther.
