Answer:
The ansewr is a barter based economy.
In a barter based economy, goods are exchanged for other goods, because no good that takes the functions of money exists (unit of account, store of value, and medium of exchange).
Barter economies can work on a limited scope, but to a larger extent, they can become inefficient, because this type of economy requires a double coincidence of wants: both parties of the transaction must desire the other party's goods.
Answer:
The present value of the contract is 0.5% higher if the rent is paid at the beginning of the month. That is equal to $11.28 for every $100 of rent.
Explanation:
if the rent is paid at the beginning of the month, the present value of the lease contract will be:
PV = monthly rent x PV annuity due factor
we are not given the monthly rent, but we know the PV annuity due factor for 0.5% and 24 periods = 22.67568
if the rent is paid at the end of the month, the PV = monthly rent x PV ordinary annuity factor
the PV ordinary annuity factor, 0.5%, 24 periods = 22.56287
assuming that the rent is $100 (just to calculate a %), the PV of an annuity due = $2,267.57
the PV of an ordinary annuity = $2,256.29
the difference between them = [($2,267.57 / $2,256.29) - 1] x 100 = 0.5%

Answer:
The production capacity the manufacturer should reserve for the last day = 206.00 units.
Explanation:
Normal production = 1000 X $ 10
Normal production = $ 10,000
Spot production = 1,000 X $ 15
Spot production = $ 15,000
p* = 15,000 - 10,000 / 15,000
p* = 0.33
Q = norminv(0.33,250,100)
The production capacity the manufacturer should reserve for the last day = 206.00 units
