"Returning to the contention that convex costs provide a resolution to the merger paradox, we show that for reasonable degrees of convexity, the minimum market share needed for merger to be profitable remains close to that associated with linear costs. Moreover, convex costs do not eliminate the...

The consequences of a demand constraint (low willingness to pay) are examined in a model of merger by spatial price discriminators. The imposition of a demand constraint reduces the extent of inefficiency associated with merger and also eliminates the resolution of the merger paradox obtained in...

"This paper is the first to examine the welfare consequences of a public firm in a traditional model of spatial price discrimination. It demonstrates that when a private firm acts as a Stackelberg location leader, the presence of a public firm always improves welfare. Moreover, when three firms...
