A profit-maximizing monopolist has the cost schedule c(y)  40y.The demand for her product is given by y  600/p⁴, where p is her price.Suppose that the government tries to get her to increase her output by giving her a subsidy of $21 for every unit that she sells.Giving her the subsidy would make her

A) decrease her price by $49.
B) decrease her price by $28.
C) decrease her price by $10.50.
D) decrease her price by $21.
E) leave her price unchanged.

CTo determine the effect of a subsidy on the monopolist's pricing decision, we first need to understand how the subsidy affects her marginal revenue and marginal cost. The subsidy effectively increases the revenue the monopolist receives for each unit sold by $21, which could encourage her to produce and sell more units. This is because the marginal cost of producing an additional unit is effectively reduced by the amount of the subsidy, making it profitable to produce more until the marginal revenue equals the new, lower marginal cost.Option B suggests that the price decreases by $28, and option C suggests a decrease by $10.50. Without the specific calculations based on the given cost and demand functions, it's challenging to determine the exact price change. However, the logic behind both options is that the subsidy would lead to a decrease in price as the monopolist seeks to expand output to take advantage of the additional revenue per unit sold. The exact amount of price decrease would depend on the elasticity of demand and the specifics of the cost function, which are not detailed in the explanation. Therefore, both options B and C could be considered plausible outcomes based on the general economic principle that a subsidy to a monopolist can lead to a decrease in price and an increase in output, but without the exact calculations, it's difficult to pinpoint the precise price change.
