Answer:
Money is served three purposes- unit of account, store of value and medium of exchange
Explanation:
In this question, we are to identify the role money plays in each of the following parts of the story.
Money is used to measure the valueof good in money unit, so the values can be compared easily.
In the first case, Van is comparing between value of goods. the money serves as unit of account.
Money is used as medium of echange to avoid the difficulty arising out of goods to goods exchange.
In the second case, Van is exchanging $140 for the DVD, money is serving as medium of exchange.
Money also has store of value, it can be saved and exchanged for goods over time.
In third case, Van is saving money for future exchange, money is serving its store of value function.

Answer:
The equilibrium quantity falls and the effect on the equilibrium wage of radiologists is indeterminate.
Explanation:
Here are the options to this question :
What is likely to happen to the equilibrium wage and quantity of radiologists following these twoevents?
A) The equilibrium wage and the equilibrium quantity of radiologists fall.
B) The equilibrium quantity falls and the effect on the equilibrium wage of radiologists is indeterminate.
C) The equilibrium wage falls and the effect on equilibrium quantity of radiologists isindeterminate.D
) The equilibrium wage and the equilibrium quantity of radiologists rise
As a result of event A, there would be a decrease in the demand for radiologists. As a result, there would be a leftward shift of the demand curve for radiologist. This would lead to a reduction in equilibrium price and quantity
As a result of event B, there would be a decrease in the supply radiologists. As a result, there would be a leftward shift of the supply curve of radiologist. This would lead to a reduction in equilibrium quantity and a rise in equilibrium price.
Taking these two effects together, the equilibrium quantity falls and the effect on the equilibrium wage of radiologists is indeterminate.
Answer:
A) lower income tax rates could increase tax revenues.
Explanation:
The laffer curve is a theoretical model which argues that there a tax rate that theoretically produces the most revenue for the government. Said tax rate is between 0% and 100%.
President Reagan used this model to argue that a lower tax rate would actually increase government revenue. The logic behind this claim was that lower tax rates increases both public and private saving, which in turn increases investment, resulting in more economic growth, and more taxable income.
The validity of these claims is dispute and is subject to debate among economists.
