Table 1 contains a production schedule for West Sixth Brewery's Smithtown Brown beer by barrels produced. What is the marginal cost of increasing production from 2 barrels to 3 barrels?
$15 (Marginal cost is determined by finding the difference between the variable costs of two quantities. Variable cost at 2 barrels is $30 and variable cost at 3 barrels is $45, the difference is $15, which is the marginal cost)
Figure 1 shows the perfectly competitive market a certain firm faces. What is the profit for this firm?
$18 (Profit is calculated as the difference between price and average total cost, multiplied by the quantity sold. So profit is (5-3)*9 = 18)
Scenario 3: Irving and his wife Gertrude decide to take their life savings of $20,000 to buy a small retail shop. They plan to make and sell tie-dyed, University of Kentucky T-shirts. They hire a professional tie-dyer for $6.00 an hour who makes 20 t-shirts per hour. The following are needed to produce the shirts: dye, costing $1 per shirt, plain white t-shirts costing $1 each and an industrial washing machine for $1000. What is the marginal cost of producing one additional T-shirt?
$2.30 (The marginal or additional cost of making one more t-shirt is $1 for the shirt + $1 for dye + 30 cents in labor cost. = $2.30)
Scenario 1: Use the following information to answer this question. Kim decides to quit her old job that paid $1,000 a month to open a flower shop in downtown Lexington. Suppose she opens her shop in a building she owns, which she could be renting out to someone else for $1,000 a month. In addition, A to Z Rental required her to sign a one year lease on the coolers needed for her shop and the rent is $200 a month. Hiring three assistants costs her $1,800 a month. Finally, the flowers, vases and other material needed for making flower arrangements average $5,000 a month. Kim's short run fixed costs are:
$2220
Goodfellas has fixed costs of $1000 for their location downtown. Table 1 contains the schedule for their variable costs. What is the average total cost if they produce 400 pizzas?
$4.63 (Average total cost is total variable cost plus total fixed cost divided by quantity produced, so we have (850+1000)/400 = $4.63)
Suppose that a firm produces 200,000 units a year and sells them all for $10 each. The explicit costs of production are $1,500,000 and the implicit costs of production are $300,000. The firm has an accounting profit of:
$500,000 and an economic profit of $200,000.
For Local Taco, total cost is $1,800 when output equals 100 tacos, and total cost is $1,000 when output is zero tacos. What are average variable costs when output equals 100 tacos?

At a firm's current output level of 200 units per week, it has 10 employees at a weekly wage of $500 each. Raw materials, which are ordered and delivered daily, cost $1,000 per week. The weekly cost of the firm's capital (building and equipment) is $1,250. Which of the following statements is correct? A. total variable cost is $5,000; total fixed cost is $2,250; total cost is $7,250 B. total variable cost is $6,000; total fixed cost is $1,250; total cost is $7,250 C. total variable cost is $1,250; total fixed cost is $6,000; total cost is $7,250 D. total variable cost is $2,250; total fixed cost is $500; total cost is $2,750 E. total variable cost is $1,500; total fixed cost is $1,250; total cost is $2,750
(B) - Total Variable Costs = labor costs + raw material costs or 10 workers X $500 + $1,000 = $6,000, Total Fixes Costs = building and equipment or $1,250 Total Costs = Total Variable Costs + Total Fixed Costs = $6,000+$1,250 = $7.250
Suppose that the government imposes a $100 excise tax on motorcycles. In response to this tax the market price of motorcycles rises by $75. Based on this information, we can conclude that consumers bear _____% of the $4 economic burden of the tax and that the demand curve is relatively more _______than the supply curve. A. 75%, elastic B. 75%, inelastic C. 25%, elastic D. 25%, inelastic
(B) - We can conclude that consumers bear 75% of the economic burden of the tax and that the demand curve is relatively more inelastic than the supply curve. The amount of the tax the consumers pay is reflected in the amount of the increase in the market price so consumers pay $75 of the $100 tax (75%) and producers must bear the burden of the remaining $25 or 25% of the tax burden. If consumers bear a larger share of the tax than producers than consumers must be relatively more inelastic than producers.

Suppose that the market equilibrium price in a perfectly competitive market is $20. Given the information about a firm in this industry found in the table above, what should the firm's output level be?
5 units of output. A profit maximizing, perfectly competitive firm will produce on output level where marginal revenue is equal to marginal cost. Since the price is equal to marginal revenue in this market structure, P = MR = $20. We need to find marginal costs from the table above. This firm will produce five units of output because this is the quantity where MR=MC=$20 or $73 - $53)

Suppose that Fayette County is considering adding a guard rail to a dangerous curve by the Kentucky river. The guard rail will cost $70,000. The average damage done to vehicles that slide off the road at the curve is $10,000. It is expected that the guard rail will prevent 5 vehicles from sliding off the road during its usable life. What should the county do?
Do not install the guard rail because the costs exceed the benefits. ( 5 x 10,000 = 50,000)

True or False - You currently manage a company that produces soccer balls and you market your product globally. You plan to expand production and export to one additional country over the next few months. You are considering country A and country B. These countries are of similar size and you expect the size of the demand for your product to be about the same in each country. However, you have been informed that the government of country A will impose a tariff on your soccer balls and the government of country B will impose a quota on the number of soccer balls you export to their country. You estimate that while both policies will reduce the number of soccer balls you sell in those countries, you will sell the same number of balls in each country. If you must select one country in which you think your company will make the biggest profit, you would be more likely to chose country A than country B.
False - As a foreign producer, you would prefer the country that uses a quota to a tariff in that with a tariff, you sell fewer unit at a higher price but must give some revenue to the government. With a quota you sell fewer units at a higher price, but get to keep all of the revenue you earn

False - It moves the price in a market toward the true market equilibrium price
True or False - The minimum wage is binding when placed below the true market equilibrium wage rate.
False - The minimum wage is binding when placed ABOVE the true market equilibrium wage rate.

Suppose you manage a distillery that produces a high end "designer" beer and a low end "discount" beer. You find that the consumer demand for your "designer" beer is relatively more inelastic to changes in price than the consumer demand of your "low income" beer. In fact |Ed| = .4 for the designer beer and |Ed| = 1.2 for the discount beer. If your goal is to increase total revenue from beer sales, which of the following would be your best strategy?
Increase the price of your high end beer and decrease the price of your low end beer
Don Franklin recently bought the Hyundai dealership in Lexington, which of the following is not a variable cost he will face when running his business? - Hiring salespeople - Making payments on the facility - Purchasing complementary beverages for service customers - Purchasing inventory
Making payments on the facility (Each of the other options are variable costs because he can adjust them in the short run as the market fluctuates. Facility payments (rent) is a fixed cost because he cannot change the amount of his payments in the short run. Only in the long run can he adjust his payments on the facility)

During the summer many businesses in Lexington stay open even though they are largely empty. Why is this?
Their variable costs are covered if they stay open (If a firm can cover their variable costs, it is profitable to stay open in the short run. This is an application of the shut down rule. If they cover variable costs, any additional revenue helps them cover some of their fixed costs. Sometimes profit maximization implies loss minimization. The business is suffering a loss, but the loss would be even greater if they shut down. Only in the long run if they cannot cover their total costs will they shut down)
