Question
Chapter 21, Problem 1CQQ
To determine
Relation between money supply and aggregate demand.
Expert Solution & Answer
Answer to Problem 1CQQ
Option ‘b’ is correct.
Explanation of Solution
Option (b):
By the theory of liquidity preference, an increase in the money supply shifts the money supply curve to the right causing the equilibrium interest rate to decrease. This stimulates consumption and investment, thereby expanding aggregate
Option (a):
Increase in money supply shifts the money supply curve to the right, which lowers the interest rate. Thus, option ‘a’ is incorrect.
Option (c):
By the theory of liquidity preference, a decrease in money supply shifts the money supply curve to the left causing the equilibrium interest rate to increase. This reduces consumption and investment, thereby contracting aggregate demand. Thus, option ‘c’ is incorrect.
Option (d):
Decrease in money supply shifts the money supply curve to the left, which increases the interest rate. Thus, option ‘d’ is incorrect.

Difference-in-Difference
In the beginning of 2001, North Dakota legalized fireworks. Suppose you are interested in
studying the effect of the legalizing of fireworks on the number of house fires in North
Dakota. Unlike North Dakota, South Dakota did not legalize fireworks and continued to ban
them. You decide to use a Difference-in-difference (DID) Model. The numbers of house fires
in each state at the end of 2000 and 2001 are as follows:
Number of house fires in Number of house fires in
Year

Show your working for full credit. (10 points)
b. Can we interpret the change in the outcome for the treatment group between 2000
and 2001 as the causal effect of legalizing fireworks on number of house fires?
Explain your answer. (10 points)

Regression Discontinuity
Birth weight is used as a common sign for a newborn's health. In the United States, if a baby
has a birthweight below 1500 grams, the newborn is classified as having “very low birth
weight". Suppose you want to study the effect of having very low birth weight on the number
of hospital visits made before the baby's first birthday. You decide to use Regression
Discontinuity to answer this question. The graph below shows the RD model:
Number of hospital visits made before baby's first birthday
