Markets and Hierarchies: Analysis and Antitrust Implications Markets and Hierarchies: Analysis and Antitrust Implications A Study in the Economics of Internal Organization Oliver E. Williamson University of Pennsylvania THE FREE PRESS A Division of Macmillan Publishing Co., Inc. ~ NEW YORK Collier Macmillan Publishers LONDON ...... 1. Toward a New Institutional Economics A broadly based interest among economists in what might be referred to as the "new institutional economics" has developed in recent years. Aspects of mainline microtheory, economic history, the economics of property rights, comparative systems, labor economics, and industrial organization• have each had a bearing on this renaissance. The common threads that tie these various studies together are: (1) an evolving consensus that received microtheory, as useful and powerful as it is for many purposes, operates at too high a level of abstraction to permit many important microeconomic phenomena to be addressed in an uncontrived way; and (2) a sense that the study of "transactions," which concerned the institutionalists in the profes­ sion some forty years ago, is really a core matter and deserves renewed attention. Unlike the earlier institutionalists, however, the current group is inclined to be eclectic. The new institutional economists both draw on microtheory and, for the most part, regard what they are doing as comple­ mentary to, rather than a substitute for, conventional analysis. The spirit in which this present book is written very much follows the ~hinking of these new institutionalists. I hope, by exploring microeconomic Issues of markets and hierarchies in greater detail than conventional analysis commonly employs, to achieve a better understanding of the origins and functions of various firm and market structures- stretching from ele­ ~entary work groups to complex modern corporations. I focus on transac­ tions and the costs that attend completing transactions by one institutional t. Among the studies that deal. directly or indirectly, with the new institutional economics are AlchianandDemsetz( 1972, 1973), Arrow ( 1969, 1974), Davis and North ( 1971), Doeringer andPiore(1971), Kornai (1971), Nelson and Winter(1973), and Ward (1971). Earlier efforts of my own to move in this direction are reported in Williamson ( 1971, 1973). For a recent S}'mposium "On the Economics of Internal Organization," in which many of the market and hierarchy issues are raised, see the Spring and Fall1975 issues of the Bell Journal of Economics. TOWARD A NEW INSTITUTIONAL ECONOMICS 3 2 MARKETS AND HIERARCHIES mode rather than another. While the relation of technology to organization remains important, it is scarcely determinative. I argue in this connection 1.1 Commons on Institutional Economics that, but for a few conspicuous exceptions, neither the indivisibilities nor technological nonseparabilities on which received theory relies to explain As Commons was aware, his treatment of institutional economics was nonmarket organization are sufficient to explain any but very simple types a highly personal effort (1934, p. 1).

Its distinction is that it expressly acknowledges the importance He considered scarcity to be ubiquitous and conflict of interest, natural played by human factors in attempting to grapple with problems of economic (1934, p. 6). He saw the central contribution of institutional economics to organization. Such considerations usually operate, if at all, only in a vague, the study of economics to be the introduction and explication of the impor­ background way. Indeed, they are altogether suppressed in many of the con­ tance of collective action.

Although references to "human nature as we know it" (Knight, 1965, the invention of institutions that produced order out of conflict, where order p. 270) occasionally appear, these rarely occupy an active role in the analysis. was defined as "working rules of collective action, a special case of which I submit, however, that more self-conscious attention to rudimentary human is 'due process of law"' (1934, p. 6). To the extent that collective action was attributes is essential if we are to accurately characterize and more ade­ successful in mitigating conflict, a greater total yield- hence, potentially, quately understand many of the problems of markets and hierarchies. a more preferred result for all of the parties- was thereby made feasible. The remainder of this chapter is an overview of the mode of analysis and His treatment of "futurity" is of special significance, where "The concept types of problems that this book is concerned with. Some of the antecedents of futurity is that of expected events, but the principle of futurity is the to the proposed approach are examined in Section 1.

The emphasis, as I interpret it, is on (1) recurrent contracting, con­ that a sensitivity to transaction costs is often essential. They also show that ducted under conditions of (2) uncertainty, and for which (3) successive the language of studying markets and hierarchies proposed herein often adaptations are needed to bring the parties into efficient adjustment.

  • Endogenous Market Power"
    Endogenous Market Power Marek Weretkay August 5, 2010 Abstract In this paper we develop a framework to study thin markets, in which all traders, buyers, and sellers are large, in the sense that they all have market power (also known as bilateral oligopoly). Unlike many IO models, our framework does not assume a priori that some traders have or do not have market power because “they are large or small.” Here, market power arises endogenously for each trader from market clearing and optimization by all agents. This framework allows for multiple goods and heterogeneous traders. We de…ne an equilibrium and show that such equilibrium exists in economies with smooth utility and cost functions and is determinate. The model suggests that price impact depends positively on the convexity of preferences or cost functions of the trading partners. In addition, the market power of di¤erent traders reinforces that of others. We also characterize an equilibrium outcome: Compared to the competitive model, the volume of trade is reduced and hence is Pareto ine¢ cient. JEL classification: D43, D52, L13, L14 Keywords: Thin Markets, Bilateral Oligopoly, Walrasian Auction The problem of the exchange of goods among rational traders is at the heart of economics. The study of this problem, originating with the work of Walras and re…ned by Fisher, Hicks, Samuelson, Arrow, and Debreu, provides a well-established methodology for analyzing market interactions in an exchange economy. The central concept of this approach is competitive equilibrium, wherein it is assumed that individual traders cannot a¤ect prices. Price taking behavior is justi…ed by the informal argument that the economy is so large that each individual trader is negligible and hence has no impact on price.

Most users of this approach acknowledge its well-known shortcomings but defend its use as a “poor man’s’’ dynamics, capable of capturing dynamic considerations in a static framework. As one example, Eaton and Grossman ( 1986) organize discussion about optimal trade policy in international oligopolistic markets around the question of whether conjectural variations are Nash-Coumot, Bertrand, or consistent in the sense of Bresnahan (1981). Their primary finding is that the optimal policy might be a tax, a subsidy, or free trade, depending on whether the exogenous conjectural variation is Nash-Coumot, Bertrand, or consistent.

February 2009 18:59 UTC Explain ‘conjectural variation’ in Cournot duopoly, evaluate its impacts and discuss the policy implication To fully understand the impacts and policy implications of conjectural variation, one must first understand the part it played in the great indeterminacy debate within marginal economics during the first half of the 20th century. Therefore, this paper shall begin with a short description and history of conjectural variation, followed by how the debates surrounding it led to the final resolution of the indeterminacy issue. The policy implications of that resolution for imperfect markets are then briefly discussed. Definition & History At the beginning of the 20th century, political economics, as it was still known then, was wrestling with the indeterminacy issue i.e.; whether an economy tended towards an equilibrium or not1. The prevailing mood of the time felt a strong need that an economy should be determinate as it was not understood then how otherwise an economy should not fall apart2. The problem was that empirical evidence strongly suggested indeterminacy, as did some of the most notable Economists of the time. F. Y. Edgeworth (1897) was considered to have given the authoritative judgement on the indeterminacy of Cournot duopoly by showing that the imposition of a quantity constraint caused the market price to oscillate inside an interval3.

    A CONJECTURAL VARIATION COMPUTABLE GENERAL EQUILIBRIUM MODEL WITH FREE ENTRY by Roberto A. De Santis* The Kiel Institute of World Economics Düsternbrooker Weg 120, 24105, Kiel, Germany E-mail: [email protected] ABSTRACT: This paper proposes a procedure to incorporate the conjectural variation approach in Computable General Equilibrium (CGE) analysis such that the strategic interaction among rival firms in international markets can be modelled. It shows how to calibrate the conjectured reactions of rival domestic and foreign firms. It also shows that the approach suggested by Harrison, Rutherford and Tarr (henceforth, HRT) is valid if Cournot competition prevails among domestic firms, among foreign firms, and between domestic and foreign firms. A conjectural variation CGE model applied to Turkey indicates that, if Cournot competition prevails between domestic and foreign firms, the results obtained under the HRT approach are very similar to those obtained under the conjectural variation approach. However, if foreign firms expect that rival domestic firms would react to their own action, then the results change dramatically. In a more competitive context, a large welfare gain from trade liberalisation can be generated. KEYWORDS: Price cost margin, Conjectural variation, CGE analysis. JEL classification: D43, D58. * I am indebted to Glenn Harrison, Thomas Rutherford, Frank Stähler and John Whalley for their valuable comments on an early stage of this paper. All errors are my responsibility. 1. Introduction The CGE modelling literature has developed quite markedly in the last two decades. Initially, these models were constructed under the assumption of perfect competition and constant returns to scale (CRS). In the middle eighties, under the wave of the ‘new trade theory’,1 models with industrial organisation features were used to study the impact of trade policy actions when industries are characterised by endogenous market structure, and the economies to scale are exploited at firm level.

The two theories assume that firms form constant expectations about their rival’s reaction during output and price competition. This study examined the validity of zero conjectural variation hypotheses within the context of the competition in Nigerian sugar industry. Using a two-stage least square analogy and data of wholesale sugar prices between January 2007 and June 2014, the study examined the interrelationships in the firms’ price and output competition. Evidence from the study showed positive conjectural variation among the sugar firms, suggesting that output and price of rival firms varied with competition. The strong interdependency among the sugar firms suggests a continued long run competition and stable price in the industry.

  • An Empirical Test of the Rent-Shifting Hypothesis: the Case of State Trading Enterprises
    Working Paper Series FSWP2001-4 An Empirical Test of the Rent-Shifting Hypothesis: The Case of State Trading Enterprises By Stephen F. Hamilton* University of Arizona and Kyle W. Stiegert University of Wisconsin-Madison Abstract: A central result in the theoretical literature on strategic trade is the ‘rent-shifting hypothesis’, the idea that government’s can employ trade policy as a precommitment device to transfer profit from foreign to domestic firms. To our knowledge, however, the rent-shifting hypothesis remains untested empirically. This paper constructs a theory-based empirical test of rent-shifting behavior that relies on observations of government precommitment variables employed through State Trading Enterprises (STEs). The analysis applies data on the delayed producer payment structure of the Canadian Wheat Board (CWB) and examines its merits as a rent-shifting mechanism in the international durum market. The model fails to reject the hypothesis that the CWB utilizes a pre-commitment mechanism in the international durum market and several nonparametric tests confirm that the observed transfer payments set by the CWB are consistent with rent-shifting behavior in the 1972-95 pre-WTO period.

  • Some Notes on Cournot and the Bargaining Problem
    Some Notes on Cournot and the Bargaining Problem BY MARC NERLOVE* WITH A FOREWORD BY OLAV BJERKHOLT^ ABSTRACT The basic ideas of Cournot and those who came after him are related to the recent work of Nash and his notion of an “equilibrium point.” It is shown that the Nash equilibrium point incorporates the main contribution of Cournot to the solution of the duopoly problem and that the major criticism that may be made against the Cournot equilibrium may also be made against the Nash equilibrium. It is then indicated to what use this weakness might be put in the study of bargaining.

One of our goals is to study in an explicitly temporal model certain ideas that are implicitly dynamic hut heretofore have been formally expressed only statically. Throughout we stress the relationship between two fundamental concepts - commitment and reaction. When we say that a firm is committed to a particular action, we mean that it cannot change that action for a certain finite (although, possibly short) period, during which time other firms might act. By a firm's reaction to another firm we mean the response it makes, possibly after some lag, to the other's chosen action. To formalize the ideas of commitment and reaction, we introduce a class of infinite-horizon sequential duopoly games.
