Chapter 8: Problem 14

A sales tax of \(\$ 1\) per unit of output is placed on a particular firm whose product sells for \(\$ 5\) in a competitive industry with many firms. a. How will this tax affect the cost curves for the firm? b. What will happen to the firm's price, output, and profit? c. Will there be entry or exit in the industry?

Short Answer

Expert verified
The imposed sales tax will shift the firm's cost curves upwards by \$1, increasing the output price and possibly decreasing the quantity. The firm's profit might remain unchanged, depending on the demand elasticity. The tax might lead to some firms exiting the industry in the short run, but in the long run, new entries might occur if the price increase is sufficient to compensate for the higher cost.

Step by step solution

01

Understanding the effect of sales tax on cost curves

A sales tax of \$1 per unit of output increases the firm's costs by exactly that amount for each unit produced. This will shift the firm's marginal and average cost curves upwards by \$1. In a graph, this will be demonstrated as an upward shift of the cost curves.
02

Analyzing effect of cost increase on price and output

Considering that the firm operates in a competitive market, all firms will experience the same increase in cost. Therefore, the price in the market will increase by the same amount as the tax, i.e., by \$1. The output might decrease slightly due to the increase in cost and the subsequent increase in price.
03

Estimating changes in profit

The increase in cost due to the tax and the increase in price might mean that the firm's profit remains relatively unchanged. However, this will depend on the elasticity of demand. If the demand for the product is elastic, the increase in price could lead to a significant decrease in quantity demanded and thus a drop in profits.
04

Considering industry entry or exit

In the short run, the tax could lead to exit of some firms if the increased cost and price results in losses for these firms. However, in the long run, as the firms adjust their production to accommodate the tax, the industry could see new entries if the increased price can compensate for the tax-induced rise in cost.

Suppose that a competitive firm has a total cost func\(\operatorname{tion} C(q)=450+15 q+2 q^{2}\) and a marginal cost function \(M C(q)=15+4 q .\) If the market price is \(P=\$ 115\) per unit, find the level of output produced by the firm. Find the level of profit and the level of producer surplus.

A number of stores offer film developing as a service to their customers. Suppose that each store offering this service has a cost function \(C(q)=50+0.5 q+0.08 \eta^{2}\) and a marginal cost \(M C=0.5+0.16 \eta\) a. If the going rate for developing a roll of film is \(\$ 8.50\), is the industry in long-run equilibrium? If not, find the price associated with long- run equilibrium. b. Suppose now that a new technology is developed which will reduce the cost of film developing by 25 percent. Assuming that the industry is in long run equilibrium, how much would any one store be willing to pay to purchase this new technology?

Consider a city that has a number of hot dog stands operating throughout the downtown area. Suppose that each vendor has a marginal cost of \(\$ 1.50\) per hot dog sold and no fixed cost. Suppose the maximum number of hot dogs that any one vendor can sell is 100 per day. a. If the price of a hot dog is \(\$ 2,\) how many hot dogs does each vendor want to sell? b. If the industry is perfectly competitive, will the price remain at \(\$ 2\) for a hot dog? If not, what will the price be? c. If each vendor sells exactly 100 hot dogs a day and the demand for hot dogs from vendors in the city is \(Q=4400-1200 P\), how many vendors are there? d. Suppose the city decides to regulate hot dog vendors by issuing permits. If the city issues only 20 permits and if each vendor continues to sell 100 hot dogs a day, what price will a hot dog sell for? e. Suppose the city decides to sell the permits. What is the highest price that a vendor would pay for a permit?

A firm produces a product in a competitive industry and has a total cost function \(C=50+4 q+2 q^{2}\) and a marginal cost function \(\mathrm{MC}=4+4 q\). At the given market price of \(\$ 20,\) the firm is producing 5 units of output. Is the firm maximizing its profit? What quantity of output should the firm produce in the long run?

A sales tax of 10 percent is placed on half the firms (the polluters) in a competitive industry. The revenue is paid to the remaining firms (the nonpolluters) as a 10 percent subsidy on the value of output sold. a. Assuming that all firms have identical constant long-run average costs before the sales tax-subsidy policy, what do you expect to happen (in both the short run and the long run), to the price of the product, the output of firms, and industry output? (Hint: How does price relate to industry input?) b. Can such a policy always be achieved with a balanced budget in which tax revenues are equal to subsidy payments? Why or why not? Explain.
