Exceptional Convergence of the Sample Variance

The case is investigated when Hoeffding's one sample U–statistic theorem for the sample variance S² is not applicable. It is shown that this occurs only when the parent distribution is the two–point distribution with jumps of equal magnitude. For this exceptional case the standardised S² is shown to converge in distribution to (1 – V )√2, where V has chi–square distribution with one degree of freedom.

RECENT DEVELOPMENTS IN THE THEORY OF NATURAL MONOPOLY

Abstract. This paper examines two important recent developments in the theory of natural monopoly, or more generally the theory of market structure. The first is a series of papers, involving Baumol with various co-authors, investigating the theory of industry structure, whilst the second is particularly associated with the names of Shaked and Sutton, and the relationship they develop between product differentiation and industry structure. The paper surveys and to some extent contrasts these two new approaches.
Baumol et al. 's contribution is seen to be in the area of clarifying the concept of natural monopoly, refining the definitions of multiproduct costs, and developing a notion of social efficiency applicable to industries where economies of scale are important. Shaked and Sutton employ a new definition of natural monopoly unrelated to market size and utilize information about consumers'income distributions to develop their notion of vertical product differentiation and natural oligopoly.
