Draw a utility function over income u( I) that describes a man who is a risk lover when his income is low but risk averse when h
is income is high. Can you explain why such a utility function might reasonably describe a person’s preferences?
1 answer:
Answer:
Suppose there is an individual who needs a certain level of income, I°, in order to stay alive. An increase in income above that level of income I° will have a diminishing marginal utility. Below I°, the individual will be a risk lover and will take unfair gambles and risks in an effort to make large gains in income. Above I°, the individual will purchase insurance against losses.

Answer:
loanable amount after Fed operation = $950 M
Securities after fed operation = $50 M
attached below is the T-account table
Explanation:
Given data:
For assets : securities = $100 M , Loans = $800 M
For Liabilities : Constant demand deposit = $1000 M
difference between the assets and liability = $100 M and this makes the Banking system unbalanced hence the Banking system needs the intervention of the Fed. and the reduction in the required reserve ratio from 10% to 5% is the right action
How with the reserve ratio reduced to: 0.05
hence required Minimum required securities after operation = 0.05 * 1000 M = 50 M
Note : Total demand deposits = securities + loanable amount
therefore loanable amount after Fed operation = $1000 M - $50 M = $950
Attached below is the T-table
When both tables are compared it can be seen that there is a significant increase in the loanable amount after the Fed's operations and increase in Loanable amount transcends to increase in Monetary base
Answer:
730 items
Explanation:
The objective of the given information is to determine the number of hamburgers UAHH should order for the following conditions:
Average daily demand 600
Standard deviation of demand 100
Desired service probability 99%
Hamburger inventory 800
The formula for a given order quantity in a fixed period of time can be expressed as :
where;
= order quantity = ???
= daily demand average = 600
L = lead time in days = 1
T = time taken = 1
z = no of standard deviation = ???
= standard deviation of usage in lead time and time taken = ???
I = present inventory level = 800
=
× standard deviation of daily demand
=
= 1.4142 * 100
= 141.42 items
From the Desired service probability 99% = 0.99; we can deduce the no of standard deviation by using the excel function (=NORMSINV (0.99))
z = 2.33
From
q = 729.5086 items
q ≅ 730 items
Therefore; the number of hamburgers UAHH should order from the following given conditions = 730 items
