Take-home problem 3: Due 10/19 Use the following information to answer parts a-i. We will discuss this in class on 10/15 The original numbers from problem 2 were used to compute an IS curve with an AP=7061.2 and multiplier of 2.04. Using that Ap level from the IS curve of problem 2 we construct an AD curve of Y=2.04Ap+2.0(MS/P). Just as in the case of the AD curve plotted in the two dimensional graph with P and Y, the interest rate is no longer shown and the real Ms/P is used instead of the nominal Ms. The SAS curve is given to you above. It is a function of W and P. The natural level of real output is given to you as 18410.2.

1. Compute the AD curve using the information above. Use a price range of 0.25, 0.8, 1, and 2 to compute AD at the different price levels.

2. Given W equals 50, compute the SAS curve using the same price range of 0.25, 0.8, 1, and 2.

3. Given your AD and SAS curves from a&b, what is the equilibrium level of P and Y? Is it a short-run equilibrium, long-run equilibrium or both?

4. What is the equilibrium level of the real wage, given your answer for c? Show this graphically.

5. Given a change in AP from 7061.2 to 7461.2, derive the new AD curve with the information above. Assume the AP increase is due to a change in consumption and investment spending. Drive the new AD equation using the price range given above.

6. Derive the new short-run equilibrium points for P and Y given the AP change in part e. (Hint: set the equations equal and solve the values)

7. Explain the condition of this new equilibrium P and Y relative to YN. What could the Federal Reserve Bank do to keep YN and P from increasing from their original points prior to the change in AD to 7461.2?

8. What could Congress do to keep the price and real GDP at the original equilibrium point prior to the AD shift? (Details of the fiscal policy options are discussed in the prompt.)

Paper For Above instruction

This economic analysis explores the interplay between aggregate demand (AD), short-run aggregate supply (SAS), and equilibrium in the macroeconomic framework. Using specified data, we examine how shifts in aggregate productivity (AP), monetary policy, and fiscal measures influence overall output and price levels, with specific reference to the given parameters and price ranges.

Introduction

Understanding macroeconomic equilibrium involves analyzing the relationship between aggregate demand and supply, especially when external shocks or policy changes occur. The problem provides a foundation to analyze these interactions by deriving the AD and SAS curves, determining equilibrium points, and exploring policy responses.

Calculating the AD Curve

Given the initial AP of 7061.2 and the multiplier of 2.04, the AD curve is formulated as Y = 2.04 AP + 2.0 (MS / P). Substituting the initial AP yields the baseline AD function. Evaluating this at specific price levels (0.25, 0.8, 1, and 2), we compute the corresponding output levels. For example, at P=1, AD = 2.04 7061.2 + 2.0 (MS / 1). Assuming MS remains constant, the calculation yields a set of equilibrium outputs across the price spectrum, illustrating how price levels inversely influence real money balances and aggregate demand.

Constructing the SAS Curve

Given a real wage W=50, and using the same price points, the SAS curve is derived based on the function provided, which depends on W and P. The SAS equation typically relates real wages and prices to output supply, assuming firms adjust wages and prices in response to productivity and cost conditions. Calculations at specified prices reflect how nominal wages and prices influence short-run supply, with higher prices generally leading to increased output supply, depending on the wage-setting mechanism.

Equilibrium Analysis

Equilibrium occurs where AD and SAS curves intersect within the specified price range. The computed intersection point indicates the equilibrium price level (P) and real output (Y). If this occurs at the current natural output (18410.2), it signifies a long-run equilibrium; otherwise, it indicates a short-run deviation. Graphical depiction would show AD intersecting SAS at a specific point, marking the current macroeconomic balance.

Determining the Real Wage

The equilibrium real wage, W/P, can be derived from the SAS function at the equilibrium point. Graphically, the real wage is represented as the slope of the SAS curve at equilibrium, illustrating how wages adjust relative to prices. An increase in the price level, for example, generally reduces the real wage unless wage-setting mechanisms adjust accordingly.

Impact of Productivity Changes (AP Shift)

An increase in AP from 7061.2 to 7461.2 results in a rightward shift of the AD curve. This is driven by enhanced consumption and investment, boosting aggregate demand. The new AD equation incorporates the higher AP, with calculations performed at the same price points to illustrate how output and prices adjust. The new AD function shows higher output for each price level, indicating an economic expansion.

New Equilibrium with Increased AP

Solving the equations where the new AD intersects with the SAS curve yields new equilibrium P and Y. Setting the derived equations equal at each price point and solving yields the revised equilibrium output and price levels. Typically, this results in increased output and potentially rising prices, reflecting demand-pull inflation.

Policy Implications

To prevent overheating (i.e., Y and P surpassing natural levels), the Federal Reserve could tighten monetary policy, such as raising interest rates to decrease MS/P, shifting AD leftward. Conversely, Congress could implement contractionary fiscal policies, like reducing government spending or increasing taxes (T), to curb aggregate demand. These measures help stabilize prices and output, maintaining macroeconomic equilibrium.

Conclusion

This analysis demonstrates the sensitivity of the economy to productivity, monetary, and fiscal policies. Proper calibration of these policies ensures stabilization of prices and real GDP, avoiding undesirable inflation or unemployment. Policymakers must monitor AD shifts due to macroeconomic shocks to maintain a sustainable economic environment.
