6. Relationship between returns to scale, isoquants, production frontiers, and cost curves The following graph shows two isoquants that represent the firm's production technology. One of the isoquants shows all of the possible combinations of labor and capital that can produce 300 units of output (q = 300), but you must determine the other isoquant's quantity given the information that follows. CAPITAL 100 90 80 70 60 50 40 30 20 10 0 0 10 20 30 40 50 LABOR 60 70 80 ¹9, = 300 90 100 Suppose the firm's production process exhibits decreasing returns to scale. Based on the graph, the level of output represented by the second isoquant is q2 =

36) 36) Vipsana's Gyros House sells gyros. The cost of ingredients (pita, meat, spices, etc.) to make a gyro is $2.00. Vipsana pays her employees $60 per day. She also incurs a fixed cost of $120 per day. Calculate Vipsana's average fixed cost per day when she produces 50 gyros using two workers? A) $2.00 B) $2.40 C) $4.40 D) $6.80 Page Ref: 369-370

b. The Yorkshire Cricket Company makes cricket bats out of lumber supplied to it by Acme Sporting Goods, which pays Yorkshire £10 for each finished bat. Yorkshire's only factors of production are lathe operators and a small building with a lathe. The number of bats per day it produces depends on the number of employee-hours per day, as shown in the table below. Number of bats per day 0 5 10 15 20 25 30 35 Number of employee-hours per day 0 1 2 4 7 11 16 22 (i) If the wage is £15 per hour and Yorkshire's daily fixed cost for the lathe and building is £60, what is the profit-maximising quantity of bats? (ii) What would be the profit-maximising number of bats if the firm's fixed cost were not £60 per day but only £30? (iii) How would Yorkshire's profit-maximising level of output be affected if the government imposed a tax of £10 per day on the company? (Hint: This tax independent from the production level.) (iv) What would Yorkshire's profit-maximising level of output be if the government…
