Firm profitability and relative firm power

This paper expands the notion of extended rivalry as cross-industry relations within the chain of production and distribution, and argues that firm power resides in the exclusivity and essentiality of the firm's function in the chain. A cross-section of U.S. manufacturing firms representing components for finished goods, capital goods, and supplies or consumable products is examined. The analysis of the three industry groups by simultaneous equation estimation provides general support for the hypothesis that firm power, as expressed in inter-industry transactions, and industry structure, is associated with firm profitability.     

Managing customer profitability in a competitive market by continuous data mining

In a near perfect market, competitive marketing strategies are often adapted dynamically and rapidly. The changes in customer behavior are resultant in unpredictable customer profitability and cause inefficient and ineffective marketing planning. In this study, by using data mining techniques, we develop a Customer Profitability Management (CPM) system to achieve marketing goals by leading customers to migrate along pre-determined and desirable tracks. The proposed system emphasizes a continuous interplay between the active and reactive monitoring procedures to identify customer shifts. It has been shown to be an effective approach to help a firm calibrate its marketing tactics with respect to different types of customers in different situations. The proposed mechanism has been applied to a telecom company with promising results.     

Relationship between innovativeness,quality, growth,profitability, and market value

The purpose of this study is to examine the relationship between innovativeness, quality, growth, profitability, and market value at the firm level. Building on concepts from a resource‐based view of a firm and organizational learning, innovation and quality literature, we propose the innovativeness–quality–performance model, which describes how a firm's capability to balance innovativeness with quality drives growth and profitability, and in turn drives superior market value. Results of structural equation models indicate that (1) innovativeness mediates the relationship between quality and growth, (2) quality mediates the relationship between innovativeness and profitability, (3) both innovativeness and quality have mediation effects on market value, and (4) both growth and profitability have mediation effects on market value. Implications for theories and practices are discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

Net neutrality and market power: The case of South Africa

Net neutrality rules have been implemented in many developed countries, often in response to concerns over network operator market power and potential blocking or throttling of content. However, developing countries typically have significantly lower levels of internet penetration and usage. Market power in respect of internet access looks quite different given that mobile is the predominant means of connection and there are often three or more mobile operators. In South Africa, there is a quasi-monopoly in the paid satellite broadcasting market and broadband providers zero-rating content from third parties (such as Netflix) may bring about more competition. We test the main theories of harm arising in the net neutrality debate, including network operator market power and exclusion among content providers using data on the number of announced prefixes and peers and IP addresses and considering examples of bundling and zero-rating conduct by operators. We find that net neutrality rules are less likely to be required in South Africa and other developing countries and that strict enforcement of such rules could in fact hinder competition in markets for content, telecommunications networks and other related markets.

Excess market value,market power,and inside ownership structure

This study is an empirical investigation of whether principal-agent problems do in fact significantly affect corporate managers' decision making, and hence the price of the firms' securities. If inside ownership structure of firms is reflected in firm market value, then agency theory leads one to expect that market value will be a positive function of the degree of inside ownership. This study demonstrates that rational investors recognize inside ownership and its resultant effect on market value. Furthermore, it is shown that excess market value as measured by the Tobin's Q-ratio is related to the level of advertising and R&D expenditure, the degree of market power as proxied by the Lerner Index, leverage, and firm size.     

Labor market power and the distorting effects of international trade

This article examines how final product trade with China shapes and interacts with labor market imperfections that create market power in labor markets and prevent an efficient market outcome. I develop a framework for measuring such labor market power distortions in monetary terms and document large degrees of these distortions in Germany's manufacturing sector. Import competition only exerts labor market disciplining effects if firms, rather than employees, possess labor market power. Otherwise, increasing export demand and import competition both fortify existing distortions, which decreases labor market efficiency. This widens the gap between potential and realized output and thus diminishes classical gains from trade.     

Market definition,market power

Market definition and market power are central features of competition law and practice but pose serious challenges. On one hand, market definition suffers decisive logical infirmities that render it infeasible, unnecessary, and counterproductive, and the practice of stating market power requirements as market share threshold tests is incoherent as a matter of empirics and policy. On the other hand, market power is often probative of the desirability of liability, yet the typically assumed functional relationship is unexplored and often implausible. These latter deficiencies are addressed through a ground-up analysis of the channels by which market power can be relevant. It is important to explicitly and simultaneously consider both anticompetitive and procompetitive explanations for challenged practices and to attend to the magnitudes of the social consequences of correct and mistaken imposition of liability in order to identify the various ways and senses in which market power bears on optimal decision-making.     

Efficiencies,market power and horizontal merger

In June 1982 the Justice Department issued itsMerger Guidelines which specify in terms of the Herfindahl index (H) what combinations of merger size and post-merger H are likely to lead to a merger challenge. This paper assesses theseGuidelines using Williamson's (1968) well-known model in which an optimal merger policy is viewed as one that considers both the price and cost consequences of merger. The Williamson model is recast in terms of H and changes in H and linked to theGuidelines. This allows an assessment of the welfare congequences of an industry merger for any given level of concentration and merger-produce changes in concentration. Among the conclusions are that, consistent with theGuidelines, higher values of H make socially successful mergers less likely, and a more appropriate, if perhaps not more feasible, focus for theGuidelines are coordination adjusted measures of concentration and merger size.     

Trademarks,market power,and information

This paper examines the advantages of market power acquired or maintained through trademark. Without denying the benefits to consumers of trademark protection, several objections to trademark-based dominant positions are raised:-1- the possibility that in certain cases the social benefits are less than the sum of private benefits, and less than the social costs, of trademark protection;-2- the link between trademarks and incorrect perceptions of quality differentials; and-3- certain problems which may arise in tying two trademarked products.     

The exercise of market power: Its treatment under the Australian and New Zealand statutes

The monopolisation sections of Australia's and New Zealand's antitrust statutes are unusual for the test by which they distinguish acceptable from unacceptable conduct: conduct is only proscribed if it is unlikely to be observed in a competitive market. This suggests that only inefficient conduct should be proscribed. However, the courts have flirted with, rather than embraced, this identification of competition with efficiency.     

Entry deterrence: The case of a buyer with market power

The model considers a seller operating under the threat of an arbitrarily large number of unknown potential entrants and facing a strategic buyer. It is shown that the seller's Nash best response function slopes downward in price-output space, while that of the buyer slopes upward. The Nash equilibrium may be associated with a lower probability of entry than the equilibrium at which the buyer behaves non-strategically. With the buyer as the Stackelberg leader, the price is shown to decrease relative to that at the Nash equilibrium, but the probability of entry may rise or fall.     

Product innovation,product–market competition and persistent profitability in the U.S. pharmaceutical industry

Increasingly, strategy scholars are exploring the relationships between innovation, competition, and the persistence of superior profits. Sustained high profitability may result when a firm repeatedly introduces valuable innovations that service previously unmet consumer demands. While the returns to the firm from each innovation may erode over time, innovation ensures that, overall, the firm maintains a high performance position. At the same time, sustained high profitability may also accrue to firms that innovate less often, but effectively avoid the competition that otherwise erodes high returns. This paper elaborates these relationships before presenting an empirical analysis of the effects of differential innovative propensities and differential rates of competition on pharmaceutical firms’ abilities to sustain profit outcomes that are above those earned by competing firms. The analysis, which is situated within the U.S. pharmaceutical industry, finds support for the expected relationship between high innovative propensity and sustained superior profitability, but no support for a link between persistence and the ability to avoid competition.

Can market power be estimated?

Simulation experiments demonstrate the strengths and weaknesses of the Panzar-Rosse, Hall, and structural approaches to estimating or testing market power. The structural model works well only if it is properly specified. The Hall methods works well in industries with constant retums to scale (CRS); however, even slight deviations from CRS lead to serious biases. Although easier to use than the structural approach, the Panzar-Rosse approach cannot distinguish between collusion and competition for some technologies. Some empirical applications of the Hall and Panzar-Rosse methods are provided.     

Common ownership,market power,and innovation

I examine the effects of overlapping ownership on market power when there are external effects across firms. This is done in an oligopoly model with cost-reducing innovation with technological spillovers where firms have an overlapping ownership structure based largely on López and Vives (2019). The model allows for Cournot competition with homogeneous product and for Bertrand with differentiated products as well as for strategic effects of R&D investment. It derives positive testable implications and normative results to inform policy.     

Diversification strategy and profitability

Prior work has shown an association between diversification strategy and profitability. This paper replicates that association using more recent and complete data and goes on to investigate the sources of the association. Theoretical arguments are advanced which predict the association which will remain once the effects of varying industry profitability are removed. Empirical tests verify this prediction and permit the discrimination between the effects of industry and diversification strategy on profitability.     

Capital costs and profitability

The paper estimates a line-of-business (LB) cost-of-capital and derives explicitly its link — in long-run competitive equilibrium — to profitability measured as LB operating income to LB assets. The ways that observed profitability differs from what would obtain in competitive equilibrium are explored.

Can market power really be estimated?

In a previous paper in this Review, Hyde and Perloff ask the question, “Can Market Power be Estimated?” using the “structural model” or two proposed alternatives. They find that none of the three methods produce consistent, meaningful results in the food and beverage industries and that simulations suggest great sensitivity of results to model misspecification. This paper offers an explanation for these disappointing results. The difficulty is that the structural model (and its proposed alternatives) is based on an overly-ambitious estimating form that over-simplifies the diversity and true complexity of oligopoly pricing. By neglecting accounting data on costs and by arbitrarily relying on an assumption that outputs are set by subtracting a constant proportion of the difference between Price and Marginal Revenue, the “structural model” and proposed alternatives try to fit an elegant form to a messy world with predictably disappointing results.
