- Kaiser's Ice Cream Parlor produces smoothies. The market for smoothies is perfectly competitive, and the price is $4.00 a smoothie. The labor market is competitive, and the wage rate is $48.00 a day. The table shows part of the workers' total product schedule. Calculate the marginal product of hiring the fourth worker and the value of the marginal product of the fourth worker. The marginal product of hiring the fourth worker is smoothies a day.

In his first two years of operation, his sales average $100 000 per year and his operating costs for wood, workshop and tool rental, utilities, and miscellaneous expenses average $70 000 per year. Now his old job at the furniture factory is again available. What is the lowest wage at which he should decide to return to his old job? Why?arrow_forwardClick to see additional instructions Consider a firm that exists for one period. The value of labour's marginal product is given by: VMP =Px MP, where P is the price of output, and MPL = 20 - 0.1L. The wage rate is $20. Assume that there are hiring and training costs of $40 per worker. If the firm expects the price of output to be $25, what is the optimal level of employment? Important note: Your answer needs to be rounded to 2 decimal places (e.g. 1.23). Any intermediate results should be rounded to at least 4 decimal places. Failure to do so may result in your answer not being accepted as a correct one.arrow_forward

If the wage is $20/hour and the hourly rental rate of a machine is $50, what should this firm do if it wants to be as productive aspossible?a. Lay off workers and use more machines.b. Hire workers and use less machines.c. Lay off workers and use less machines,d. Hire workers and use more machines.e. Nothing. This firm is already operating efficiently.arrow_forwardI Collado Lumber Company is producing tons of lumber per day. The following table is the costs of production. The managers currently have six machines. The price of output is $5 per unit. The wage of the worker is $55 per worker. From economic theory, we know that the value of the marginal product is price times the marginal product of labor. According to economic theory, a worker should be hired if the value of the marginal product is greater than the marginal cost of hiring a worker. See the table below.
