Uncertainty and entry deterrence

Summary. We study a model where capacity installation by an incumbent firm serves to deter others from entering the industry. We argue that uncertainty about demand or costs forces the incumbent to choose a higher capacity level than it would under certainty. This higher level diminishes the attractiveness of deterrence (Proposition 1) and, therefore, the range of parameter values for which deterrence occurs (Proposition 2).

Profit sharing as a worker discipline device

A synthesis of profit-sharing and efficiency wage models is constructed to provide a preliminary account of how a firm determines its pay parameters, and why it chooses to be a profit-sharing or a fixed-wage firm. We find that the properties of the worker's effort function crucially influence the firm's choices between different compensation systems, and that the adoption of a profit-sharing scheme cannot guarantee the attainment of full employment. Other findings of the paper also seem to be very different from those of Weitzman's share model.     

Vertical product differentiation and entry deterrence

I study how a potential entrant influences quality in a model of vertical product differentiation with quality-dependent production costs. With identical costs, the incumbent will always deter entry if possible, i.e., if fixed costs are high. Quality will be set at a level lower than or equal to the optimal quality under either duopoly or monopoly. Results are completely different when the entrant has substantially lower costs. They are explained by the relative location of the entrant's quality best response to the incumbent's optimal quality choice in monopoly. This sheds new light on the influence of industrial policy on market conduct.     

Predation,reputation, and entry deterrence

Economists often argue that predatory practices are irrational, since there exist cheaper or more certain means to gain or maintain a monopoly. Our gametheoretic, equilibrium analysis suggests that if a firm is threatened by several potential entrants, then predation may be rational against early entrants, even if it is costly when viewed in isolation, because it yields a reputation which deters other entrants. Asymmetric information plays a crucial role in our analysis, since it provides the rationale for entrants to base their expectations of the firm's future behavior on its past actions. The analysis also suggests methods to treat general reputational phenomena.     

Forward induction and entry deterrence: an experiment

The Dixit (Econ J 90:95–106, 1980) hypothesis that incumbents use investment in capacity to deter potential entrants has found little empirical support. Bagwell and Ramey (J Econ 27:660–680, 1996) propose a model where, in the unique game-theoretic prediction based on forward induction or iterated elimination of weakly-dominated strategies, the incumbent does not have the strategic advantage. We conduct an experiment with games inspired by these models. In the Dixit-style game, the incumbent monopolizes the market most of the time even without the investment in capacity. In our Bagwell-and-Ramey-style game, the incumbent also tends to keep the market, in contrast to the predictions of an entrant advantage. Nevertheless, we find strong evidence that forward induction affects the behavior of most participants. The results of our games suggest that players perceive that the first mover has an advantage without having to pre-commit capacity. In our Bagwell–Ramey game, evolution and learning do not drive out this perception. We back these claims with data analysis and a theoretical framework for dynamics.

The effect of exit on entry deterrence strategies

Recent analyses of entry deterrence strategies have required an incumbent's post-entry output or pricing strategy to be profit maximizing. However, most papers have continued to assume that either an incumbent can commit not to exit after entry or that exit is never optimal. When there are avoidable fixed costs of operating in any period, however, exit can be the optimal strategy. In this situation, entry deterrence strategies operate very differently than when exit is never optimal. In fact, the possibility of exit can make some, previously effective, strategies completely ineffective while improving the effectiveness of others.     

Strategic sourcing for entry deterrence and tacit collusion

By sourcing key intermediate goods to a potential entrant, an incumbent firm can credibly and observably commit to an intense post-entry competition, thereby deterring the entry. At the same time, a collusive effect exists, whereby the entrant’s loss from staying out of the final-good market is compensated through their sourcing transaction. We find that entry-deterring sourcing in general has ambiguous effect on social welfare. However, there exist scenarios where it enhances not only social welfare, but also consumers’ surplus.     

Strategic pricing and entry deterrence under price-cap regulation

This paper shows that dynamic price-cap regulation allows the regulated firm to deter entry. Under dynamic price-cap regulation, the allowed prices in each period are an increasing function of the prices set in the previous period. By setting a low price before entry, the regulated firm can commit itself to charge a low price in the event of entry. If this price is sufficiently low with respect to the potential entrant's fixed cost, entry does not occur. Whether the regulated firm prefers to deter or accommodate entry depends on the level of the entry cost for the prospective entrant, on the tightness of the price-cap and on the degree of market power of the competing firms in case of entry.     

Branch banking, entry deterrence, and technology decisions

The paper sets up a theoretical model of banking firms to investigate the relationship between oligopolistic competition and technology structure by using the concept of decentralized operating decisions and centralized investment decisions. It concludes that the representative branch and the new entrant will choose the technology which is deviated from its cost-minimization level if neither of them acts as a quasi-competitive deposit demanders in the case of costless reversibility of capacity decision. In the case of capacity reversed not costlessly, the representative branch will choose the cost-minimizing technology level and the entrant's technology decision depends on its rival's conjectural variation.     

Profit sharing in a competitive environment

Nearly all theoretical discussions of profit sharing to date have, following Weitzman, assumed that firms are monopolistic or monopolistically competitive. The present paper investigates the employment effects of a profit sharing scheme in a competitive environment. It is found that profit sharing can actually reduce employment in the long run, since the profit share may produce subnormal profits and exit of existing firms.     

Profit sharing under the threat of nationalization

A multinational corporation engages in foreign direct investment for the extraction of a natural resource in a developing country. The corporation bears the initial investment and earns as a return a share of the profits. The host country provides access and guarantees conditions of operation. Since the investment is totally sunk, the corporation must account in its plan not only for uncertainty in market conditions but also for the threat of nationalization. In a real options framework, where the government holds an American call option on nationalization, we show under which conditions a Nash bargaining leads to a profit distribution maximizing the joint venture surplus. We find that the threat of nationalization does not affect the investment threshold but only the Nash bargaining solution set. Finally, we show that the optimal sharing rule results from the way the two parties may differently trade off rents with option values.     

Union-oligopoly bargaining and entry deterrence: a reassessment of limit pricing

This paper introduces wage bargaining in the framework of Milgrom and Roberts (Econometrica 50(2):443–459, 1982) where the workers’ reservation wage is the private information parameter critical for entry. We show that entry threat significantly distorts the wage, which in some cases adversely affects the firm’s ability to signal through price. Consequently, the separating equilibrium (in price) does not always exist. If, however, wage agreements are made public, signalling occurs with or without distortions in wage depending on whether the union’s bargaining power is high or low. Pooling equilibrium also exists and it features similar distortions. We also examine which signal, wage or price, generates greater social welfare. We would like to thank two referees for their helpful comments and suggestions. This paper is partially based on a chapter of Pal’s PhD thesis done at Indira Gandhi Institute of Development Research (IGIDR), India. For remaining errors we are solely responsible.     

Profit sharing and strike activity in Cournot oligopoly

Within an incomplete-information framework, we develop a model of wage determination in a unionized Cournot oligopoly. The assumption of incomplete information allows the possibility of strikes or lockouts, which waste industry potential resources, at equilibrium. Facing such deadweight loss, the government or the social planner may decide to adopt a policy, such as a profit-sharing scheme. Under two different bargaining structures (firm level vs. industry level), we investigate the effects of adopting profit sharing on the wage outcome and the strike activity. If the base-wage bargaining takes place at the industry level, then the introduction of a profit-sharing scheme increases the strike activity. But if the base-wage bargaining takes place at the firm level and the number of firms in the industry is greater than two, then the introduction of a profit-sharing scheme reduces the strike activity.     

Staggered contracts and profitable entry deterrence: an application to professional sports

This paper examines an incumbent league's entry-deterrence strategies in a professional-sports market. The strategy of staggering long-term contracts offered to star players is analyzed and shown to reduce the wage bill of an incumbent league. However, if long-term contracting reduces player effort, the incumbent balances the benefits of a lower wage bill with the cost of reduced sales revenues. An optimal contract duration in the presence of such moral hazard is characterized in terms of the parameterization of the model. Extensions to the model are also discussed.     

Profit taxation and the mode of foreign market entry

Abstract This paper studies the role of profit taxation for an international firm's decision upon how to penetrate a foreign market – through exports or through foreign direct investment (FDI) and local supply. We show that with harmonized taxes the international firm may choose FDI even though this has welfare costs from a global point of view. With tax competition, the host country can enforce exporting instead of FDI. This leads to a Nash equilibrium associated with higher world welfare than harmonized taxes. Thus, because of the effect on entry mode, tax competition provides heretofore unexplored benefits as compared to tax harmonization.     

Profit sharing and firm size: The role of team production

This paper presents a model showing that profit sharing is subject to the 1/N problem in the case of independent worker productivity but not in the case of interdependent worker productivity. This implies the role of firm size on the likelihood of profit sharing will differ by the nature of the underlying technology. We test this implication using German establishment data and using a proxy for interdependent worker productivity. The results conform to the theory showing that firm size is associated with reduced profit sharing use when technology is independent but not when technology is interdependent.     

Profit sharing in unique Nash equilibrium: Characterization in the two-agent case

Two agents jointly operate a decreasing marginal returns technology to produce a private good. We characterize the class of output-sharing rules for which the labor-supply game has a unique Nash equilibrium. It consists of two families: rules of the serial type which protect a small user from the negative externality imposed by a large user, and rules of the reverse serial type, where one agent effectively employs the other agent's labor. Exactly two rules satisfy symmetry; a result in sharp contrast with Moulin and Shenker's characterization of their serial mechanism as the unique cost-sharing rule satisfying the same incentives property [Moulin, H., Shenker, S., 1992. Serial cost sharing. Econometrica 60 (5), 1009–1037]. We also show that the familiar stand-alone test characterizes the class of fixed-path methods under our incentives criterion [Friedman, E.J., 2004. Strong monotonicity in surplus sharing. Econ. Theory 23, 643–658].     

Strategic bypass deterrence

In liberalized network industries, competitors can either compete for service using the existing infrastructure (access) or deploy their own capacity (bypass). We revisit this make-or-buy problem making two contributions to the literature. First we analyze both the profit maximizing behavior of an incumbent and the welfare maximizing behavior when the entrant chooses between access and bypass. Second, we extend the baseline model studied in the literature by allowing for fixed costs of network installation. By analogy to the literature on strategic entry deterrence, we distinguish three régimes of blockaded bypass, deterred bypass and accommodated bypass depending on the entrant’s unit cost. We show that the make-or-buy decision of the entrant is not necessarily technologically efficient: when bypass is chosen, it is always the cheapest option but access may be chosen when it is not cost effective.     

Incentive efficient risk sharing in a settlement mechanism

The purpose of this paper is to address a question concerning risk management in continuing, multi-party, contractual, clearing and settlement arrangements through which large-value payments are typically made. We are particularly interested in the issues of incentive compatibility when a third party possesses a private information concerning the riskiness of transfers being made. If a third party possesses private information that would be of value in determining how best to settle a payment, how does the exposure of that party to the settlement risk affect the quality of information that the party chooses to provide? In this paper, we address this question by analyzing a specific class of parametric environments of a schematic, formal, model of a settlement arrangement or a payment network.     

Entry deterrence through credit denial

Firms in oligopoly can use debt to commit to a strategic position that negatively affects rival firms and improves profitability. In this paper, I show that an incumbent firm can deter entry by using debt to commit to such a low price that an entrant's lender will not finance entry, even if the entrant's expected profit from entry is positive. Empirical evidence shows that concentration and debt are positively related in several industries, indicating that debt may be used to reduce competition.
