If a single large employer bargains with an inclusive union,the resulting labor market model can best be described as:

A) a cartel.
B) countervailing power.
C) a bilateral monopoly.
D) an internal labor market.

The scenario of a single large employer bargaining with an inclusive union results in a bilateral monopoly, which is a market structure where a single buyer faces a single seller. The employer holds a monopoly position in the labor market, while the union holds a monopoly position in the labor supply. As such, both parties have significant bargaining power, and the resulting wages and working conditions are determined through negotiations between the two sides. This situation is different from a cartel where multiple sellers collude to increase prices or countervailing power where a buyer has power over multiple suppliers. An internal labor market refers to the practice of promoting employees from within an organization rather than hiring from outside.
