Spatial price theory has typically assumed homogeneous gross demand curves among buyers who are dispersed over an economic landscape. Subtracting varying costs of distance to their locations yields a set of heterogeneous net demand curves. Any spatial monopolist subject to these conditions faces separable markets which are characterized by different effective demands. As a result price discrimination is feasible, and in theory straight-lined delivered price schedules of less than unit slope per unit cost of distance are customarily derived. But do spatial competitors ever discriminate (or appear to discriminate) over economic space? And if they do, what is the form of their delivered price schedules? Would their schedules also be linear given the same demand conditions that generate linear schedules for a discriminating monopolist? Without answering questions such as those raised above anti-trust regulations dealing with unfair price practices and, in particular, the determination of what is legal or illegal, ethical or not, cannot be readily accepted by economists. The present paper is designed to provide a basis for answering such questions by uncovering selected properties of spatial price discrimination under conditions of varying intensities of competition over an economic space. More generally, the paper is designed to determine the effect on prices of rival locations and the intensity of their competition. Sharp contrasts between spaceless and spatial price theory will thus be drawn, with competitive differences over the seller's trading area being revealed to generate differential discriminatory prices over the landscape.

Discriminatory pricing by railroads may be better than marginal cost pricing with a subsidy of the resulting losses, since it gives the railroad correct incentives for deciding what rail lines to build. The argument, applied to longhaul/short-haul discrimination, shows that its prohibition may lead to nonoptimal construction decisions. [Авторский текст]

This paper reexamines the theory of spatial price policies under more general conditions to compare mill pricing, uniform delivered pricing, and discriminatory local pricing and to interpret their implications when market regions are given. The analysis assumes that demand functions are linear and identical in all locations, that marginal production cost is constant, and that transportation cost is proportional to distance. The results go beyond previous findings, but do not seriously contradict them. [Авторский текст]

This paper applies conventional welfare-theoretic methods to study advertising which changes consumer tastes. In a wide range of empirically plausible circumstances, private profitability is seen to be necessary but not sufficient for the social desirability of a small amount of advertising. The market equilibrium level of such advertising is shown to be socially excessive, even when postadvertising tastes are used as the standard for welfare judgments and the monopoly profits resulting from the advertising are included in welfare. Settings of monopoly, oligopoly, and monopolistic competition are examined, and the contention that advertising is excessive is found to be strengthened at each stage. [Авторский текст]

We have demonstrated that zero pure profit is not a necessary condition of free-entry equilibrium in a model in which the market is spatially extended and longrun cost curves decline over some initial range. We have shown that neither price competition among existing firms nor the entry of new firms will necessarily drive profits to zero. This is true even when firms assume that they can cut their own price without reaction from their competitors, and when new entrants rationally calculate whether or not their entry will force existing firms to relocate. We have further shown, in a specific example, that rates of return on capital of up to twice the competitive rate are possible in free-entry equilibrium. The model of this paper is formulated in terms of geographical differentiation among firms. There would seem, however, to be significant applications to product differentiation, where firms sell products with different locations in characteristics space, and a new product fitting in between two established ones must expect a market significantly smaller than those obtained by "neighbouring" products before entry. For a discussion of some of the issues involved in handling monopolistic competition in characteristic space see Archibald and Kosenbluth (1975) and for a practical application that uses some of the properties developed in our model see Schmalensee (1977).

This note extends the conventional short-run comparison of perfectly competitive and monopsony markets to show that the long-run monopsony equilibrium implies a greater divergence from the competitive results than is true in the short run. The conditions necessary to have a 'pure' monopsony, with power in only the labour market, are developed and generate a constant marginal revenue product of labour equal to the competitive wage. This leads the monopsonist to cut wages and labour inputs further in the long run and also forms the upper bound on the bargaining range for a union negotiating with a pure monopsonist.

The paper of which this is an enlarged and revised version was read at a joint Round Table of the American Economic Association and the Econometric Society, during the meetings at Philadelphia, December, 1939. Where one of the conditions of perfect competition is absent, the presence of others may lead to greater rather than less imperfection. Long-run curves of individual demand and cost are flatter than commonly represented, and the imperfections of competition correspondingly less. Industry subject to fluctuating demand requires prices in excess of short-run marginal cost. Favorable conditions appear to include a sloping individual demand curve, and some uncertainty whether a reduction of price will be promptly met. With standardized products, a chaotic market tends toward ruinous competition. Pure oligopoly is seldom found; the important case being that of openly-quoted prices with varying amounts of deviations on actual sales. Standard products with sloping individual demand curves are also possible. While extreme quality differentials approach monopoly, more moderate ones may be workably competitive, especially with further growth of closer substitutes and better knowledge of qualities on the part of buyers.

Фундаментальная книга по отраслевой организации, которая считается учебником, хотя напоминает монографию (на первое английское издание очень много ссылок в научной литературе). Книга написана свободным ясным языком. Обсуждение скорее вербальное и графическое, чем формальное. Плюсы книги - хорошая формулировка теоретических проблем и богатая библиография, недостатки - отсутствие учебных атрибутов (вопросы, задачи).
