The market for all lawn care equipment shipped annually in the United States is approximately $16 billion, according to the Outdoor Power Equipment Institute, a trade organization based in Alexandria, Va. Most of it is bought by homeowners, and their choices are changing. For example, while gas-power mowers still dominate sales, “the speed at which battery-powered alternatives are gaining ground is notable,” said Grant Farnsworth, the president of the

- Q. Wilpen Company, a price-setting firm, produces nearly 80 percent of all tennis balls purchased in the United States. Wilpen estimates the U.S. demand for its tennis balls by using the following linear specification: Q = a + bP + cM + dPR. Where Q is the number of cans of tennis balls sold quarterly, P is the wholesale price Wilpen charges for a can of tennis balls, M is the consumers’ average household income, and PR is the average price of tennis rackets. The regression results are as follows: a. Discuss the statistical significance of the parameter estimates a^, b^, c^, and d^ using the p-values. Are the signs of b^, c^, and d^ consistent with the theory of demand? Wilpen plans to charge a wholesale price of $1.65 per can. The average price of a tennis racket is $110, and consumers’ average household income is $24,600. b. What is the estimated number of cans of tennis balls demanded? c) At the values of P, M, and Pr given, what are the estimated values of the price (E^), income…arrow_forwardEdison's Fire Engines is the sole seller of fire engines in the fictional country of Pyrotania. Initially, Edison produced eight fire engines, but he has decided to increase production to nine fire engines. The following graph shows the demand curve Edison faces. As you can see, to sell the additional engine, Edison must lower his price from $80,000 to $60,000 per fire engine. Note that while Edison gains revenue from the additional engine he sells, he also loses revenue from the initial eight engines because he sells them all at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial eight engines by selling at $60,000 rather than $80,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $60,000. 100 90 PRICE (Thousands of dollars per fire engine) 8 80 70 60 50 40 30 10 0 Edison 0 1 O True 2 O False + 6 3 4 5 7 QUANTITY (Fire…arrow_forwardImagine that you run the toll authority for a city bridge. You must charge all of your customers the exact same toll. Initially, you have set the price at $2 per trip. The blue line on the following graph shows the weekly demand curve for trips across the city bridge. On the following graph, use the purple rectangle (diamond symbols) to shade the area representing the total weekly revenue when the toll is $2 on the graph. Notice that when you click on the rectangle, the area is displayed.

To analyze this, use the green rectangle (triangle symbols) to shade the area representing the total weekly revenue when the toll is $3 on the graph. When the toll is $2, total revenue is S per week, but when the toll is $3, total revenue is $ per week. Based on your analysis, you can…arrow_forward
- The demand function for a certain model of Blu-ray player is given by 300 p = 0.5x + 1 where p is the unit price in dollars and x (in units of a thousand) is the quantity demanded per week. What is the consumers' surplus if the selling price is set at $150/unit? (Round your answer to the nearest dollar.)arrow_forwardFlorida, like several other states, has passed a law that prohibits “price gouging” immediately before, during, or after the declaration of a state of emergency. Price gouging is defined as “selling necessary commodities such as food, gas, ice, oil, and lumber at a price that grossly exceeds the average selling price for the 30 days prior to the emergency.” Many consumers attempt to stock up on emergency supplies, such as bottled water, immediately before and after a hurricane or other natural disaster hits an area. Also, many supply shipments to retailers are interrupted during a natural disaster. Assuming that the law is strictly enforced, what are the economic effects of the price gouging statute? Explain carefully.arrow_forward6. A record company estimates the industry demand for "hard alternative rock" albums to be: QD-1000 -125 P. It estimates the industry supply to be: QS = 125-P a. Given these estimates, what does it expect the industry output and price to be? b. A government commission announces that lyrics on "hard alternative rock" albums are offensive and should be banned. This causes consumers to purchase 20% more of such albums at any given price, compared to question 6a. What effect will this have on industry output and the price? c. Calculate the consumer surplus for parts a and b above. Are consumers better or worse off given the commission's recommendation?arrow_forward

Luchansky and Monks (2009) estimated that the U.S. demand function for ethanol is Q = p-0.504pg 1.2692.226, where Q is the quantity of ethanol, p is the price of ethanol, pgis the price of gasoline, and v is the number of registered vehicle. What is the elasticity of demand for ethanol.arrow_forwardOver the last three years, Christmas tree prices have increased from an average of $35 per tree to over $75 per tree. How would a Christmas tree farm and the overall industry respond to the price change under the following circumstances? Be sure to explain how your answer depends on the elasticity of supply. The price increase is a result of fewer Christmas tree farms harvesting trees in response to consumers purchasing more artificial trees. The effect of the price increase on the Christmas tree industry will be as follows: *In the long run, the industry supply curve shifts to the left. *In the long run, as tree farms sell fewer trees, they make losses and exit the industry. *In the short run, the increase in price leads to profits for tree farms. *In the short run, the tree farms exit the Christmas tree business and grow other lucrative plants.arrow_forwardDemand for Corn Flakes is: P = 14 - Q. Supply of Kellogg's Corn Flakes is: P = 2 + Q. Now a generic company enters the market, selling generic Corn Flakes for $4. Assume consumers are indifferent between generic and Kellogg's Corn Flakes. When the generic corn flakes enter the market, Kellogg's will sell how many less boxes of their own cereal?arrow_forward
- Charles's Fire Engines is the sole seller of fire engines in the fictional country of Pyrotania. Initially, Charles produced five fire engines, but he has decided to increase production to six fire engines. The following graph shows the demand curve Charles faces. As you can see, to sell the additional engine, Charles must lower his price from $160,000 to $120,000 per fire engine. Note that while Charles gains revenue from the additional engine he sells, he also loses revenue from the initial five engines because he sells them all at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial five engines by selling at $120,000 rather than $160,000.

Imagine you are taking an online class, and you are looking to buy a new computer because your old one died. The class starts in two days. The market for computers is very competitive. There are several brands that have similar characteristics, such as storage capacity, processor speed, number of USB ports, etc., but you have owned one that you liked, and you want to buy that same brand, the X-Mark. You have a budget of $1,750. One popular store has the brand you like on sale for $999.99 because other stores sell them for that price. You have a friend at that store who tells you that the store paid $925 for that computer.
