| 金声玉亮2.0 | D. pays less and hires fewer. In a monopsony, a single buyer has market power over the input market, allowing them to pay a lower price for the input (in this case, labor) than would be paid in a competitive market. This is because the monopsonist can restrict the quantity of labor hired to drive down the wage. As a result, the monopsonist pays less for labor and also hires fewer workers than would be hired in a competitive market. |

| deepseekr1 | D. pays less and hires fewer **Explanation**: In a competitive input market, equilibrium occurs where the supply of labor (reflecting the wage rate) equals the marginal revenue product (MRP) of labor. A monopsony, however, faces an upward-sloping supply curve, meaning the marginal factor cost (MFC) of hiring additional workers exceeds the wage rate. The monopsonist hires workers up to where MFC = MRP, which results in a lower quantity of labor hired compared to the competitive market. The wage paid is then determined by the supply curve at this reduced quantity, which is also lower than the competitive wage. Thus, a monopsony pays less and hires fewer workers than a competitive market. |

In a monopsony, a single buyer has market power over the input market, which allows them to pay a lower price for the input (in this case, labor) than would be paid in a competitive market. This is because the monopsonist can restrict the quantity of labor demanded, which drives down the wage.

| wenxinyiyan | D Explanation: A monopsony is a market structure where there is only one buyer facing many sellers. This gives the monopsonist (the single buyer) significant market power. Relative to a competitive input market, a monopsonist will use this market power to pay lower prices to the sellers and, as a result, hire fewer inputs (e.g., workers). This occurs because the monopsonist can exploit the sellers' lack of alternative buyers to negotiate lower prices, but at these lower prices, fewer sellers will be willing to sell their inputs. Therefore, the correct answer is D: pays less and hires fewer. |

| zhipu | D. pays less and hires fewer In a monopsony, there is only one buyer (or employer) of a particular input (such as labor). This gives the monopsonist significant market power, allowing them to set wages lower than in a competitive market. As a result, the monopsonist pays less for the input and hires fewer units of the input compared to what would occur in a competitive input market. This is because the monopsonist maximizes profit by equating the marginal cost of hiring an additional unit of input to the marginal revenue product of that input, which typically results in lower wages and a lower quantity of input hired. |
