The following table shows the relationship between the number of trainers working at the new gym (SD Fitness) and the number of clients they can train per week. These clients represent the output of the firm. Clients pay $60 per hour. Find the Marginal Product (MPL) for the 4th, 5th and 6th trainer.  Find the Value of Marginal Product (VMPL) of the 4th, 5th and 6th trainer.  SD Fitness’s trainers are paid $650 per week. How many trainers will the gym hire? How do you know?
Consider a profit-maximizing cotton candy firm that operates in a perfectly competitive output and labor market. Suppose there is a decrease in the price of good X, and the cross-price elasticity of demand for cotton candy with respect to good X is positive. How does this impact: a. the wage paid to cotton candy workers b. the amount of labor hired by the cotton candy firm? Explain and show using well-labelled graphs.

  • Use the following image to answer:    The first is a (human) worker, who must be paid $18 for each hour they spend producing chairs. The second is a robot, that costs $15 of inputs (including electricity and maintenance) for each hour it works. Assume that the sale price of chairs is always sufficiently high that it is profitable to fulfill this 80-chair order. The firm needs to make 80 chairs to fulfill its order. Assume also that the firm is profit maximizing (& therefore cost minimizing).    Now suppose that the local economy increases the minimum wage, and the price of an hour of a worker’s time increases from $18 to $27. 1) What does the principle of substitution say should happen to the firm’s use of (i) worker hours and (ii) robot hours?    Pls show full calculations
    Jess owns a firm that uses labour (L) and capital (C) to sell widgets (X), according to the following production function: X = F(L,C) = ln(L) + ln(C) Jesse buys her factors and sells her output in perfectly competitive markets. The market prices for L, C and W are a, r and p, respectively.  What is the firm’s profit function.  What is the  firm's marginal product of labour , marginal product of capital  and marginal rate of technical substitution  Does the firm exhibit a diminishing marginal product of capital? What is the firms demand functions for labour and capital.  Say the central bank decides to increase interest rates, causing ? to go up. What effect will this have on the firm’s use of L and C? What effect will it have on output (X) and profits?
    If the marginal revenue earned by a firm due to an additional unit of worker is less than the marginal cost of hiring him, _____. a.the firm should not hire the worker b.the firm should hire the worker c.the firm should not operate in the long run d.the firm should not differentiate its products
  • Candice’s’ Cookies is a new cookie delivery company in Gainesville, Florida. The firm hires local college students to sell cookies door-to-door in higher income neighborhoods. Each of these “Sales Associates” sells cookies, which increases Candice’s Cookies’ total revenue, but must be paid an hourly wage. The graph below depicts Candice’s Cookies’ demand for labor curve when the retail price of a cookie is $2.   Show Transcribed Text Part (i): Suppose that the retail price of a cookie is $2.50. What is the marginal product of the 4th Sales Associate? 1 cookie 2 cookies 3 cookies 4 cookies 5 cookies   Part (ii): Suppose that the retail price of a cookie is $2.50. What is the marginal product of the 6th Sales Associate? 1 cookie 2 cookies 3 cookies 4 cookies 5 cookies   Part (iii): Suppose that the retail price of a cookie is $2. What is the marginal product of the 8th Sales Associate? 1 cookie 2 cookies 3 cookies 4 cookies 5 cookies

    A firm employs two workers. Together, these workers produce 30 oranges. The firm hires a third worker. Total output rises to 36 oranges. If orange growing is a perfectly competitive market where the price of an orange is $0.50, find the value of the marginal product of labor of the third worker.
