Answer:
b. Firm A engaged in predatory pricing.
Explanation:
Since Firm A and B are the only two companies that sell mail-order DVD rental subscriptions.
Firm A decided to price its subscriptions below average variable cost thereby causing Firm B to also sell subscriptions below average variable cost, but they went bankrupt and exited the market. Firm A then raised prices by 40% and is currently earning large, positive economic profits.
Based on this information only, an argument can be made that Firm A engaged in predatory pricing.
Predatory pricing is a marketing or pricing strategy that involves lowering the cost of goods and services for a short-term, in order to lure competing firms to lower their price, thus causing them to go bankrupt and exiting from the market.
Answer:
Suppose the cost per hour incurred in operating a cruise ship is 3a + b 
dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.)
<em>The speed at which the ship would maximize cost is </em>![\sqrt[3]{\frac{3a}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3a%7D%7B2b%7D%20%7D)
Explanation:
The problem can be solved using differentiation to get the minimum value of the speed to travel between the two ports. Step by step calculation is contained in the attached images;
Answer:
Price of stock = $40
Explanation:
According to the dividend growth model, the price of a stock is the present value of expected dividend discounted at the required rate of return.
This is done as follows:
Price of a stock = D×(1+r)/(r-g)
D(1+g) - Dividend for next year = 100%-40%× $3 = $1.8
g- growth rate - 10%
r- required rate of return - 15%
Price of stock = 1.8× (1.1)/(0.15-0.1)
= $40
Firstly, you should calculate the prices of your market basket, which basically means multiply all the goods with their prices and then add them together in their respective years. This would give you $260, $440, $690 and $1200 in the years 2010 to 2013 respectively. (follow along by noting everything down)
We see that the base year is 2013, therefore if we want to calculate the inflation rate from 2010 to 2011, we have to calculate their price indices. We do this by dividing the maket basket of our chosen years by the market basket of the base year, therefore the price index of 2010 is $260/$1200, giving us 21.6. The price index of 2011 would be $440/$1200, giving us 36.6. To calculate the inflation rate, you find the difference between your two price indices and divide it by the former year, which would be 36.6 - 21.6 / 21.6 x 100, giving us the inflation rate of 69.2%.
Answer: $100 million
Explanation:
National Income (GDP) for a close nation is calculated as:
= Consumption + Investment + Government spending
Making investment the subject would give us:
Investment = GDP - Consumption - Government spending
= 400 - 150 - 150
= $100 million
