Relation between money supply and aggregate

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 demand. Thus, option ‘b’ is correct.
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.
Concept introduction:
Aggregate demand (AD): Aggregate demand refers to the total value of the goods and services that are demanded at a particular price in a given period.
Money supply: Money supply refers to the total amount of monetary assets circulating in an economy during a particular period.

- 5. Discrimination in the labor market The following table exhibits the name, gender, height, and minimum wage 10 people are willing to accept to work as human resource specialists at a large financial firm. Name Gender Height Minimum Wage (Inches) (Dollars per week) Paolo M 67 $298 Ginny F 63 $311 Lucia F 66 $332 Eric M 71 $354 Kenji M 69 $375 Sharon F 66 $397 Paolo M 70 $411 Carlos M 70 $440 Van M 64 $452 Amy F 69 $474 The lowest weekly wage that the financial firm can spend in order to hire five human resource specialists is____. Suppose the hiring director of the financial firm prefers taller candidates because they think it will increase revenue, and so they impose a requirement that all newly hired human resource specialists must have a height of at least 67 inches. With this mandate in place, the weekly wage rate the financial firm now must pay in order to hire five human resource specialists increases by_____.arrow_forwardnot use ai pleasearrow_forwardnot use ai pleasearrow_forward

Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
