The typical consumer's food basket in the base year 2015 is as follows: 30 chickens at $4 each 10 hams at $5 each 10 steaks at $8 each a chicken feed shortage causes the price of chickens to rise to $5.00 each in the year 2016. hams rise to $7.00 each, and the price of steaks is unchanged. a. calculate the change in the "cost-of-eating" index between 2015 and 2016. year cost of the basket 2015 $ 2016 $ instructions: enter your responses rounded to one decimal place. the official cost-of-eating index has by %. b. suppose that consumers are completely indifferent between two chickens and one ham. for this example, how large is the substitution bias in the official "cost-of-eating" index? the in the cost-of-eating index is %. the of inflation in the cost of eating reflects substitution bias.

Suppose a firm faces a fixed price of output, 푝푝= 1200. the firm hires workers from a union at a daily wage, 푤푤, to produce output according to the production function 푞푞= 2퐸퐸12. there are 225 workers in the union. any union worker who does not work for this firm is guaranteed to find nonunion employment at a wage of $96 per day. a. what is the firm’s labor demand function? b. if the firm is allowed to choose 푤푤, but then the union decides how many workers to provide (up to 225) at that wage, what wage will the firm set? how many workers will the union provide? what is the firm’s output and profit? what is the total income of the 225 union workers? c. now suppose that the union sets the wage, but the firm decides how many workers to hire at that wage (up to 225). what wage will the union set to maximize the total income of all 225 workers? how many workers will the firm hire? what is the firm’s output and profit? what is the total income of the 225 union workers? [hint: to maximize total income of union, take the first order condition with respect to w and set equal to 0.]
