A firm that unilaterally moves away from the mid‐point loses Buyers are uniformly distributed in a line of length one, where L is the left end and R the right end. This paper reports the results of an experimental study of the three agent location problem. Suppose, however, that there is only one firm, and that this monopolist is (exogenously) located at the left end point of the interval (y 1 = … PRACTICE PROBLEMS 8 Topic: Hotelling’s model and product differentiation ... 3.
