Chapter 10, Problem 4E
To determine

(a)

What is the spending multiplier, when MPC=0.90 and MPI=0.10

Expert Solution
Check Mark

Explanation of Solution

We have

  MPC=0.90

  MPI=0.10

Also, MPC+MPS=1

  MPS=1MPC

  MPS=10.90

  MPS=0.10

Thus, multiplier is calculated as

  Multiplier = 1MPS+MPI

  Multiplier = 10.10+0.10

  Multiplier = 10.20

  Multiplier = 102

  Multiplier = 5

Hence, the value of multiplier is 5

Economics Concept Introduction

Concept Introduction:

Multiplier is defined as the ratio of change in equilibrium income with the initial change in autonomous expenditure

  Multiplier = change in equilibrium income or real GDPChange in autonomous expenditure

Also, multiplier can be measured from the leakages

  Multiplier = 1Leakages

  Multiplier = 1MPS+MPI

Where MPS= Marginal Propensity to save

  MPI= Marginal Propensity to invest

To determine

(b)

What is the spending multiplier, when MPC=0.90 and MPI=0.20

Expert Solution
Check Mark

Explanation of Solution

We have

  MPC=0.90

  MPI=0.20

Also, MPC+MPS=1

  MPS=1MPC

  MPS=10.90

  MPS=0.10

Thus, multiplier is calculated as

  Multiplier = 1MPS+MPI

  Multiplier = 10.10+0.20

  Multiplier = 10.30

  Multiplier = 103

  Multiplier = 3.34

Hence, the value of multiplier is 3.34

(c)

What is the spending multiplier, when MPC=0.80 and MPI=0.30

Expert Solution
Check Mark

Explanation of Solution

We have

  MPC=0.80

  MPI=0.30

Also, MPC+MPS=1

  MPS=1MPC

  MPS=10.80

  MPS=0.20

Thus, multiplier is calculated as

  Multiplier = 1MPS+MPI

  Multiplier = 10.20+0.30

  Multiplier = 10.50

  Multiplier = 105

  Multiplier = 2

Hence, the value of multiplier is 2

Explanation of Solution

We have

  MPC=0.90

  MPI=0.10

Also, MPC+MPS=1

  MPS=1MPC

  MPS=10.90

  MPS=0.10

Thus, multiplier is calculated as

  Multiplier = 1MPS+MPI

  Multiplier = 10.10+0

  Multiplier = 10.10

  Multiplier = 101

  Multiplier = 10

Hence, the value of multiplier is 10

Answer
M” method  Given the following model, solve by the method of “M”. (see image)
As indicated in the attached image, U.S. earnings for high- and low-skill workers as measured by educational attainment began diverging in the 1980s. The remaining questions in this problem set use the model for the labor market developed in class to walk through potential explanations for this trend.  1. Assume that there are just two types of workers, low- and high-skill. As a result, there are two labor markets: supply and demand for low-skill workers and supply and demand for high-skill workers. Using two carefully drawn labor-market figures, show that an increase in the demand for high skill workers can explain an increase in the relative wage of high-skill workers.  2. Using the same assumptions as in the previous question, use two carefully drawn labor-market figures to show that an increase in the supply of low-skill workers can explain an increase in the relative wage of high-skill workers.
