Answer:
$1,248
Explanation:
The current premiums are $975, which is equivalent to 100%. The new premium will increase by 28%.
New premiums will be $975% plus 28%, which is equal to 128% of $975
= $975 x 128/100
=$975 x 1.28
=$1,248
Answer: 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
Explanation:
Q=1200 - 4P and Q=-240 + 2P
In a free market quantity demand =quantity supplied
1200 -4P = -240 +2P
P =240
Sub P
Q* = 240
Socially optimal quantity is
Marginal social benefit (MSC)= marginal social cost(MSC), including external damage =MEC
MPC= marginal private cost =inverse of supply function
MPC = (1/2)*Q + 120
MEC=12
MSC =(MPC +MEC) = (1/2)Q +120 +12
MSC= MPB where MPB is marginal private benefit = inverse of demand functn
MPB = 300 -(1/4)Q
(1/2)Q + 132 =300 - (1/4)Q
Q° = 224
Difference btw Q* & Q° = 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
Answer:
$739.72 ≈ 739.72
Explanation:
we can use an excel spreadsheet and the present value function to calculate the expected price of each bond ⇒ =PV(rate,nper,pmt,fv,[type])
- fv = $1,000
- pmt = $1,000 x 7.25% x 1/2 = $36.25
- nper = 60
- rate = 10% / 2 = 5%
- present value = ?
=PV(5%,60,36.25,1000) = -739.72 since excel calculates the initial investment, it is always negative, so we just change the sign.
