- The American Baker’s Association reports that annual sales of bakery goods last year rose 15 percent, driven by a 50 percent increase in the demand for bran muffins. Most of the increase was attributed to a report that diets rich in bran help prevent certain types of cancer. You are the manager of a bakery that produces and packages gourmet bran muffins, and you currently sell bran muffins in packages of three. However, as a result of this new report, a typical consumer’s inverse demand for your bran muffins is now P = 8 – 1.5Q.

- Julia has usual preferences over X and Y, and, at current prices and income, she spends 1/2 of her income on X. Her demands for both goods respond to changes in her income, but at current prices and income the income elasticity of her demand for Y is equal to exactly 1/3 times the value of her income elasticity of demand for X. And do you know what? If the price of Y were to go up by 1 percent, the quantity of X she demands would remain unchanged. a. If the price of X were to fall, would her demand for X increase, decrease or remain unchanged? More precisely, what is the own-price elasticity of her demand for X? b. If her income were to rise, would her demand for X rise, fall or remain unchanged? More precisely, what is the income elasticity of her demand for X?Market researchers estimate that the annual demand for ice cream in Gotham city is: qi = (200,000Pp1/4)/ (Pi3/2Pb1/2) where qi is the quantity demanded for ice cream in scoops, Pp is the price serving of pudding, Pb is the price per serving of brownies, and Pi is the price per scoop of ice cream. a.

Your job is to use the cross-price elasticity between splishy splashers and the other goods to determine which goods your marketing firm should advertise together. Complete the first column of the…
- You are a manager in charge of monitoring cash flow at a major publisher. Paper books comprise 40 percent of your revenues, which grow about 2 percent annually. You recently received a preliminary report that suggests the growth rate in ebook readings has leveled off, and that the cross-price elasticity of demand between paper books and ebooks is -0.3. In 2016, your company earned about $600 million from sales of ebooks and about $400 million from sales of paper books. If the own price elasticity of demand for paper books is -2, how will a 4 percent decrease in the price of paper books affect your overall revenues from both paper books and ebooks sales? (Enter your response rounded to one decimal place.) Your overall reveues will change by $____ million.Substitutes, complements, or unrelated?

The number of times per year that she plays depends on both the price of playing a round of golf as well as Lorena’s income and the cost of other types of entertainment—in particular, how much it costs to go see a movie instead of playing golf. The three demand schedules in the table below show how many rounds of golf per year Lorena will demand at each price under three different scenarios. In scenario D1, Lorena’s income is $50,000 per year and movies cost $9 each. In scenario D2, Lorena’s income is also $50,000 per year, but the price of seeing a movie rises to $11. And in scenario D3, Lorena’s income goes up to $70,000 per year, while movies cost $11. a. Using the data under D1 and D2, calculate the cross-elasticity of Lorena’s demand for golf at all three prices. (To do this, apply the midpoints approach to the cross-elasticity of demand.) Is the cross-elasticity the same at all three prices? Are movies and golf substitute goods, complementary goods, or…

He has set a $150 budget and will choose golf balls that will give him as much utility as possible. A local sporting goods store sells a box of golf balls at a retail price of $30 and Tommy purchases 2 boxes. A few buddies tell Tommy about an online store that offers boxes of golf balls at a discounted price of $21, while all other prices remain the same, and Tommy decides to purchase 3 additional boxes of golf balls to keep on hand. Given this information, plot Tommy's demand curve for golf balls.
