Answer:
A. Landscape lawns produce positive externality.
B. Sports vehicle generates a positive externality
C. Walk to work creates positive externality.
D. Cigarettes create a negative externality.
Explanation:
Positive externality occurs when society gets benefit from a persons act. Susan has created lawns near her house and there are beautiful flowers in the lawn. This will be relaxing for those who pass near by the lawns. There will be fresh air coming from the lawn and society will look pleasant.
Negative externality is one in which society is harmed by the act of a person. This happens when Anita smokes at a bus stop. There are other travelers who will be present at the bus stop might be harmed from the smoke which arises from the cigarette.
Answer: raise; reduce
Explanation:
A Supply shock is described as a situation where the supply of a good changes suddenly/ abruptly due to an unforeseen event.
Supply shocks can be positive but are usually negative so we will assume the supply shock is negative here.
If there is a negative supply shock, the amount of goods being produced will reduce abruptly which will force the supply curve to shift left.
It will then intercept the the demand curve at an equilibrium level that has a higher price and a lower quantity of output.
Think of it this way. Negative supply shock ⇒ less goods ⇒ scarcity ⇒ higher prices.
Answer and Explanation:
The computation is shown below:
Debt = D ÷ (E + D)
= 0.8 ÷ (1 + 0.8)
= 0.4444
Now
Weight of equity = 1 - Debt
= 1 - 0.4444
= 0.5556
As per Dividend discount model
Price = Dividend in 1 year ÷ (cost of equity - growth rate)
40 = $2 ÷ (Cost of equity - 0.06)
Cost of equity = 11%
Cost of debt
K = N
Let us assume the par value be $1,000
Bond Price =∑ [(Annual Coupon) ÷ (1 + YTM)^k] + Par value ÷ (1 + YTM)^N
k=1
K =25
$804 =∑ [(7 × $1000 ÷ 100)/(1 + YTM ÷ 100)^k] + $1000 ÷ (1 + YTM ÷ 100)^25
k=1
YTM = 9
After tax cost of debt = cost of debt × (1 - tax rate)
= 9 × (1 - 0.21)
= 7.11
WACC = after tax cost of debt × W(D) + cost of equity ×W(E)
= 7.11 × 0.4444 + 11 × 0.5556
= 9.27%
As we can see that the WACC is lower than the return so it should be undertake the expansion
Answer:
The answer is C.
Explanation:
Macroeconomics is the study of the economy as a whole, unlike microeconomics which is the study of the individual firms/markets.
Macroeconomics focuses on the standard of living, unemployment rate, inflation rate etc. and how this affects the whole economy.
Option A is wrong because it is the microeconomics and not macroeconomics that studies the market and the firm.
Option B and D are wrong because these are for microeconomics
