    -  Table 1 shows that price followship is the dominant strategy up to point short of the cartel level depending on how close the firms' goods are as substitutes.  Given the Bashkar model, the goods are closer substitutes as the value of slopes a and b near equality.   When the goods are close substitutes, the followship demand curve is less elastic and the cartel price rises far above the noncooperative dominant strategy level.
