Vertical integration as a remedy for imbalances in the ‘Porterian’ value system. The Dutch financial securities industry at the beginning of the 20th century

The way of accounting for vertical integration, of this paper is based on the ‘Porterian’ value system and focuses on the relation between the creation and appropriation of value. The essence of a value system is that at each stage in the system value is created and added to the value created at previous stages. We propose that firms which are unable to appropriate the value they create at the stage they currently inhabit, would find it advantageous to integrate vertically towards stages offering a more attractive relation between value appropriation and value creation. This argument will be illustrated here by the case of a large Dutch bank that integrated vertically towards securities trading.

Entry into Swedish Retail and Wholesale Trade Markets

This paper examines, using a zero-inflated negative binomial regression model, what determined entry into the Swedish retail and wholesale trade markets between 1990 and 1996. According to the results, high returns on equity and low sunk costs seemed to attract more entry into retail trade industries, while recent entry and higher total industry sales were associated with more entry into both retail and wholesale trade local markets.     

Integration of FSU/economies in transition into the World Trade Organization1

Membership of the World Trade Organization is a goal for many transition economies. This paper discusses what is involved in WTO membership, the information required and the commitments imposed upon members. After reviewing the accession process in general, the topic is illustrated by the recent example of Bulgaira and Mongolia.     

Competition, Externalities, and Input Substituting Technologies

The period 1997–2000 saw a rapid global consolidation of crop seed companies. The emerging companies are applying genetic engineering to exploit complementarities and substitutabilities between seed and other crop inputs. This article develops a model of competing technologies where one substitutes for a conventional input. A monopolist may cross-subsidize a technology that substitutes for an input in order to price discriminate between user types. In duopoly, a socially excessive or insufficient share of acres may be subject to an input substituting technology. Welfare improving regulations are identified in the case where a technology substitutes for an externality generating input.

Distinguishing between Equilibrium and Integration in Spatial Price Analysis

This article introduces a new spatial price analysis methodology based on maximum likelihood estimation of a mixture distribution model incorporating price, transfer cost, and trade flow data. This method permits differentiation between market integration and competitive market equilibrium and derivation of intuitive measures of intermarket tradability, competitive market equilibrium, perfect integration, segmented equilibrium, and segmented disequilibrium. One can also use these estimates to derive semiparametric measures of time-varying regime probabilities to track changing market conditions. An application to trade in soybean meal among Pacific Rim economies demonstrates the usefulness of the method.     

Rent-seeking in a unionised monopoly

A unionised monopoly firm, benefitting from some kind of anti-competitive regulation, and its corresponding trade union have a common interest in spending resources to protect the monopoly rents created by the regulation. In the present paper, a situation in which the unionised monopoly is challenged by a consumer organisation fighting for deregulation is analysed as a standard Tullock rent-seeking contest. With unequal sharing of monopoly rents, the free-riding incentives among the rent-defending players turn out to be overwhelming, in the sense that the unique Nash equilibrium is characterised by zero effort contribution by the player with the lower valuation of the contested prize. This implies that being “strong”, in terms of bargaining strength, is not necessarily an advantage for neither player in a unionised monopoly that is threatened by deregulation.

论美国多轨制对外贸易政策的形成与经济效应

20世纪70年代初,经济实力相对衰弱迫使美国对外贸易政策更加务实,构成了美国实行多轨制对外贸易政策的主要原因。实行多轨制对外贸易政策以来,美国经济结构进一步软化和其他国家的贸易摩擦进一步增加。多轨制对外贸易政策的实质是全面的贸易保护,其目的在于保护本国弱势部门,发展本国强势部门,是一种以绝对优势作为制定对外贸易政策基础的贸易管理方式。
