d. vertical

Answer 1

1.) In a competitive market, the firms are price takers, which means that they have no control over the price and just accept the price as given. However, in monopoly, the firm is a price maker which means that the firm decides the price to charge. Therefore, the correct answer is option b. A competitive firm is a price taker, and a monopoly is a price maker. 2.) In a monopoly, the equilibrium is at the intersection of marginal revenue and marginal cost curves. Therefore, the output produced is less than that of a competitive firm and thus, is inefficient. Therefore, the correct answer is option a. an inefficiently low quantity of output. 3.) Calculate the monopolist's profit as follows:

Profit =(P-ATC)x Quantity =(8-5)x100 = 3x100 = 300 Therefore, the correct answer is option b. $300. 4.) In a monopoly, there is no defined supply curve because the monopolist makes decisions not only on the basis of marginal cost but also the demand. Therefore, the correct answer is option d. The supply curve does not exist. NOTE: As per the guidelines of Chegg, first question ought to be answered. However, first four questions have been answered here.
