Chapter 19, Problem 8DQ
ADVANCED ANALYSIS Suppose that a government wants to reduce its economy’s dependence on coal and decides as a result to tax coal mining companies $1 per ton for every ton of coal that they mine. Assuming that coal mining companies treat this tax as an increase in extraction costs this year, what effect will the tax have on current extraction in the model used in Figure 17.7? Now, think one step ahead. Suppose that the tax will be in place forever, so that it will also affect extraction costs in the future. Will the tax increase or decrease user cost? Does this effect increase or decrease the change in current extraction caused by the shift of the EC curve? Given your finding, should environmental taxes be temporary? LO17.4

You expect KT Industries (KTI) will have earnings per share of $4.6 this year and expect that they will pay out $1.66 of these earnings to shareholders in the form of a dividend. KTI's return on new investments is 11% and their equity cost of capital is 16%. KTI's dividend growth rate is _________ (Round to two decimal places) If KTI's dividend growth rate will remain constant, and KTI's next year dividend is $1.78, then KTI's current stock price should be ________ (Round to two decimal places)

- The government wants to enact tax legislation aimed at reducing increasing discharge levels of toxins into municipal waste water systems. The annual cost of the tax to the 100 worst industrial polluters will be $5 million each. The annual benefits of the tax, in terms of reduced toxin levels in water systems, are valued at $25 per person. There are 300 million people directly affected by the 100 worst industrial polluters. The total cost of this tax is _____________________ while the total benefit to society is _____________________.

The company has branches in all the regions in Ghana with its head office located at Cape Coast. It employs 1,200 people and pays an average of GH¢ 550.00 as income tax to the government of Ghana on a monthly basis. Suppose that seven thousand, eight hundred and twenty (7,820) units of Quin are produced and supplied by Sharp Inc. but the quantity demanded for Quin is eight thousand (8,000) units. Ceteris Paribus, a GH¢ 20.00 change in the price of Quin results in a change in quantity demanded for and supplied of 4 and 5 units, respectively. [Hint: change in X due to change in Y is given as Ax]. Given the above information: a) Determine the equilibrium price and equilibrium quantities of Quin. b) Suppose the Government of Ghana in the wake of the COVID-19 pandemic grants a subsidy of GHs 4.50 on each Quin produced.

- Q5) A firm is planning to manufacture a new product. The sales department estimates that the quantity that can be sold depends on the selling price. As the selling price is increased, the quantity that can be sold decreases. Numerically they estimate: P = $35.00 - 0.02Q where P =selling price per unit Q = quantity sold per year On the other hand, the management estimates that the average cost of manufacturing and selling the product will decrease as the quantity sold increases. They estimate C = $4.00Q + $8000 where C = cost to produce and sell Q per year The firm's management wishes to produce and sell the product at the rate that will maximize profit, that is, where income minus cost will be a maximum. What quantity should the decision makers plan to produce and sell each year?arrow_forwardA herbal tea producer company has 24 different products in the market, each are produced in one of the 3 factories owned by the company. The weights of the products in monthly sales may vary depending on time of the year (demands of certain products shift to others in each of the 4 seasons), age of the products and market conditions, but yearly aggregate demand has a very strong correlation with the price of the product (Here, we ignore any other factor and assume that the yearly aggregate demand is directly and linearly effected by the price). The company found out that when the price for a packet of 20 herbal tea bags is 10 TL, yearly demand is 175000 packets. When the price increases to 11 TL, demand decreases to 174650 packets. On the cost side, the company has 2900000 TL of yearly administrative costs regardless of the price or the number of units sold, including the rents, depreciation of the buildings and other related assets and salaries of 58 workers (average monthly salary…arrow_forwardA herbal tea producer company has 24 different products in the market, each are produced in one of the 3 factories owned by the company.

Suppose that a technological breakthrough means that extraction costs will fall in the future (but not in the present). What will this do to future profits and, therefore, to current user cost? Will current extraction increase or decrease? Compare this to a situation where future extraction costs remain unchanged but current extraction costs fall. In this situation, does current extraction increase or decrease? Does the firm’s behavior make sense in both situations? That is, does its response to the changes in production costs in each case maximize the firm’s stream of profits over time?arrow_forward
