The economy of Lower Slobovia is currently experiencing an interest rate of $12 \%$ and a real GDP of $$\$ 5,000$$. The level of aggregate demand puts it in the Keynesian range of the country's aggregate supply curve and perfectly elastic range of the country's labor supply curve. Suppose the government has announced its intent to achieve a target interest rate of $6 \%$ and a real GDP level of $$\$ 10,000$$. Further assume this action would still leave the economy in the perfectly elastic ranges of its aggregate supply and labor market supply curves. a. Identify the specific macroeconomic policy action you would recommend the government to take to achieve these twin targets. b. What impact will the change in the general economy have on the market equilibrium for wheat in Lower Slobovia? c. What impact would you expect the macroeconomic policy you recommended in part $a$ on an individual wheat producer's average profit? Total profit?

Key Concepts

Producer Profit Analysis (Average vs. Total Profit)

In response to a more robust economy, individual producers may see increases in total profits owing to higher sales volumes, even if average profit margins per unit remain unchanged. This analysis distinguishes between average profit (profit per unit, which might be more stable if costs rise proportionately with revenue) and total profit (which can increase significantly with an uptick in overall sales volume), reflecting the broader impact of macroeconomic changes on microeconomic behavior.

Spillover Effects into Sectoral Markets

Policy changes aimed at boosting overall economic activity often have indirect effects on specific markets. As aggregate demand increases due to expansionary fiscal policy, sectors like wheat production may experience increased demand due to higher incomes and spending power. This can lead to higher equilibrium prices and greater quantities sold in those individual markets.

Expansionary Fiscal Policy

This concept involves the government increasing its spending or reducing taxes in order to stimulate overall economic activity. When an economy is in the Keynesian range of its aggregate supply curve, such fiscal measures can increase aggregate demand without causing inflationary pressures, thereby helping to boost output and achieve specific policy targets such as higher real GDP and lower interest rates.

Aggregate Demand and Keynesian Economics

Aggregate demand is the total spending on an economy's goods and services at a given price level. In the Keynesian framework, especially in the flat portion of the aggregate supply curve, shifts in aggregate demand—often brought about by fiscal policy changes—directly impact real GDP and employment, with minimal changes in the price level. This idea underlies the policy recommendation in the scenario.

Market Equilibrium in Macroeconomic and Microeconomic Contexts

Market equilibrium refers to the state where supply equals demand in a market, determining the equilibrium level of prices and output. Macroeconomic policies, such as expansionary fiscal policy, can shift aggregate demand and thereby affect overall economic equilibrium, which in turn can spill over into individual markets, such as that of wheat, influencing prices and quantities traded.

Transcript

00:01 And in question eight, question eight says, as described in the chapter, the federal reserve in 2008 faced a decrease in aggregate demand caused by the housing and financial crises and a decrease in short -run aggregate supply caused by rising commodity prices.

00:15 Part a asks, starting from a long -ground equilibrium, illustrate the effects of these two changes using both an aggregate supply, aggregate demand diagram, and a phillips curve diagram.

00:25 On both diagrams, labeled the initial long -run equilibrium as point a and the resulting short -run equilibrium as point b.

00:33 For each of the following variables, state whether it rises or false or whether the impact is ambiguous.

00:38 Output employment price level and inflation rate.

00:41 All right.

00:42 So here i've drawn two graphs and state that there are two possibilities.

00:48 I explain what this means in a while.

00:49 But let's take a look at the first graph on the top left, standard aggregate supply, demand graph.

00:56 As always, the long -rate aggregate supply curve will be vertical.

01:00 It will intersect the x -axis at the natural level of output y -1.

01:05 And the economies at the point a, which is the intersection of ad1 and sras -1.

01:13 So point a is a long -run equilibrium.

01:16 And we know that the economy is facing a very negative shock and aggregate demand.

01:22 So the ad curve shifts from 81 to 82.

01:25 Right here, shifts to that left.

01:28 And on the other hand, we also have a negative aggregate supply shock from rising commodity prices.

01:36 So the short run aggregate supply curve shifts also shifts to the left from sras1 to sras2 right here.

01:43 So the resulting recessionary equilibrium will be at point b, which is the intersection of ad2 and sras2.

01:51 And this will result result unambiguously in a lower level of output, y2.

01:58 So the difference between y1 and y2 is a recessionary gap.

02:02 So here in the first graph, we can see that the price level will drop from p1 to p2.

02:11 However, if we take a look at the diagram at the bottom, i've drawn exactly the same diagram, but with a little change, the average demand curve shifts less.

02:26 As compared to the shorter aggregate supply curve, and the new equilibrium results again, a lower level output, but results in a higher price level, p2.

02:38 So we can say that the impact on the price level is ambiguous because it depends on the magnitude of the change of the aggregate demand and aggregate supply curve.

02:47 So if the aggregate demand shock is more adverse, the price level will drop.

02:52 If the aggregate supply curve is more adverse, the price level will rise because companies will adjust their protection plans accordingly to reflect this supply shock.

03:04 So just for the sake of exposition, we're going to assume that the price level will rise because this is easier to illustrate in the phillips curve diagram, which i have drawn here on the right.

03:14 As always, the long grand phillips curve intersects the x axis at the natural level of output u1.

03:20 The economy is initially at point a, which is the intersection of the long grand phillips curve with it...
