Import Quotas and Entry Deterrence

Using a simple version of the Milgrom and Roberts entry deterrence model, it is shown that adjusting a quota so that a greater volume of imports is allowed, can facilitate entry into the domestic industry. That is, the easing of a quota, can cause the domestic incumbent to shift from deterring entry to accommodating entry.     

Entry Deterrence in a Unionized Oligopoly

We investigate wage determination between an incumbent firm and its labour union under threat from another firm entering its product market. In equilibrium, it may be optimal for a labour union of the incumbent firm to lower its wage demand. This may make it possible for the incumbent firm to maintain a higher employment level, in that the lower wages can help the firm deter the entry of a rival firm. This will yield a higher profit for the incumbent firm and a lower utility level for the labour union compared with those in an equilibrium with no threat of entry.

Campaign War Chests, Entry Deterrence, and Voter Rationality

It is often claimed that the accumulation of "war chests" by incumbents deters entry by high–quality challengers in Congressional elections. This paper presents a game–theoretic analysis of the interaction between an incumbent, potential challengers, an interest group, and a representative (rational) voter, where the incumbent's "quality" (or "legislative effectiveness") is known to the interest group, but not to the voter or to potential challengers. Under certain conditions, a perfectly revealing equilibrium exists; the incumbent signals her quality by raising funds from the interest group to accumulate a war chest. The entry deterrence effect thus operates solely through the role of war chests in signaling incumbent quality.     

An Efficient Avoided Cost Pricing Rule for Resale of Local Exchange Telephone Services

The Telecommunications Act of 1996 requires incumbent local exchange telephone companies to make their retail telecommunications services available to resellers at a discount that reflects the costs that will be avoided by providing the services at wholesale rather than at retail. In this article, we develop a pricing methodology to apply to such wholesale services. The methodology, which we label the Avoided Cost Pricing Rule, is designed to generate an economically efficient discount that may be applied to the incumbent local exchange carriers' services that are offered to resellers.     

Entry Deterrence and Entry Accommodation Strategies of a Multiproduct Firm Regulated with Dynamic Price Cap

In this paper we study the way a multiproduct firm, regulated through a dynamic price cap, can develop a price strategy that uses the regulatory policy to deter entry. We consider a firm that initially operates as a monopolist in two markets but faces potential entry in one of the markets. We conclude that the regulated firm can have the incentive to block the entry. This strategy leads to the reduction of the price in both markets. However, the final effect of the entry deterrence strategy on total consumer surplus is not always positive.     

Strategic Choice of the Price Structure and Entry Deterrence Under Price Cap Regulation

This paper shows that a price‐capped firm under the threat of entry in some of the markets it serves can strategically manipulate its price structure to deter entry. In doing so, the regulated firm uses the price cap constraint as a commitment device to an aggressive pricing behaviour in case of entry. A (dynamic) price cap generally entails that the prices allowed today are a function of the previous‐period prices and that the tighter is the constraint on each price, the larger is the quantity sold of this good in the previous period. Hence, the regulated firm may strategically choose its price structure before entry to place a tighter regulatory control on the prices set in the (potentially) competitive markets and to make it optimal to charge in these markets – in case of entry – prices so low that entry is unprofitable.     

Incentive Regulation and Efficient Pricing

Abstract ** :  One objective of introducing incentive regulation to the newly privatized UK utilities over the past 20 years was to encourage efficient pricing structures. Caps have been imposed on average price levels, giving firms freedom to rebalance amongst prices within the basket. We test how firms have responded to the incentives within such discretion through an extensive review of the relative prices charged within UK price capped industries. We find surprisingly little response to these incentives, suggesting that strategic behaviour dominates short‐term profit incentives even after the introduction or threat of competition .     

策略性掠夺性定价及反垄断规则

策略性掠夺性定价理论显示,掠夺性定价是一种合理的企业策略性行为.掠夺性定价的策略性实施包括两个基本的要素:一是牺牲短期利润;二是在长期能够通过行使市场势力来收回短期损失.通过对主要的掠夺性定价检验规则和加拿大、美国、欧共体的反垄断执法实践的分析,本文认为基于乔斯科-克莱沃里克的两阶段检验规则是较优的掠夺性定价执法规则.     

Strategic Reaction of Vertically Integrated Firms to Downstream Entry: Deterrence or Accommodation

The purpose of this paper is to analyze strategic behavior of vertically integrated firms when there is downstream entry, taking into account the balance between competition in the market and competition for the market. This analysis can serve to explain diverse distributional structures, including the coexistence of vertically integrated firms and independent retailers. And it shows that the relative efficiency of downstream entrants and the level of competition among incumbents are two major factors in determining equilibrium configuration.     

Competition Between Exclusive Religions: The Counter‐Reformation As Entry Deterrence

This article sets forth a theory of competition between exclusive religions as an entry deterrence game, in which the incumbent may find it profitable not to accommodate but to deter the competitor's entry by precommitting to sufficient capacity expansion in the event of entry. If entry costs are high enough, deterrence is optimal and the incumbent remains a monopolist, although the entry threat distorts its effort upward. The model is then applied to the Catholic Church's reaction to the Protestant Reformation. It is argued that the model provides a better fit to the historical data of the Counter‐Reformation than the price‐cutting model proposed by economists Ekelund, Hébert and Tollison ( 2004 , 2006 ).     

Universal Service and Entry: The Role of Uniform Pricing and Coverage Constraints

Universal service objectives are pervasive in telecommunications, and have gained new relevance after the introduction of competition in many markets. Despite their policy relevance, little work has been done allowing for a thorough discussion of instruments designed to achieve universal service objectives under competition. We intend to fill this gap, and disaggregate the problem into interacting forms of regulatory intervention such as uniform pricing and coverage constraints. It is shown that these are not competitively neutral and may have far-reaching strategic effects. Under uniform pricing, equilibrium coverage of both incumbent and entrant may be lower than without regulation. These effects depend on which measures are imposed at the same time, thus no single measure can be evaluated in isolation. We also point out that different groups of consumers are affected in different ways, making welfare comparisons difficult.     

Efficient Entry,Monopoly, and the Universal Service Obligation in Postal Service

This paper analyzes the nature of and justification for the Universal Service Obligation (USO) and its relationship to the Reserved Area for Postal Service. This is motivated by problems of funding the USO in the face of increasing competition in the postal sector. After reviewing various approaches to defining and funding the USO, we develop a model to consider the optimal scope of both the Reserved Area and the USO. The model assumes an incumbent postal provider and potential entrants. The incumbent is guaranteed a monopoly franchise for services in its Reserved Area R and offers services in a possibly larger set of services U at uniform prices. All services not in R face competition from entrants. We characterize the welfare-optimal scope of R and U subject to a breakeven constraint for the incumbent. Implications for USO policy are discussed in light of the results of the analysis.     

Negotiated Enforcement and Credible Deterrence

This paper develops a model of law enforcement in which indicted offenders and the prosecutor can negotiate the penalty prior to the completion of the investigation. The analysis focuses on the credibility of the conviction threat: the prosecutor cannot commit to any predetermined level of investigative effort should the negotiation fail. The settlement stage introduces several new features of the optimal enforcement policy, including the possibility that maximal sanctions may not be optimal. We show that the screening process associated with the negotiation stage reduces the incentives for the prosecutor to undertake thorough investigations and increases the rate of noncompliance.     

Entry Threats and Inefficiency in ‘Efficient Bargaining’

We study limit pricing in a model of entry with asymmetric information, where the incumbent firm's wage is endogenously determined through ‘efficient bargaining’ with its union. In the presence of entry threat, the incumbent firm‐union pair may face a conflict between rent sharing and transmitting its cost information. When the wage is not observable to outsiders and employment is the only signalling instrument, over‐employment features in all entry deterring contracts. When the wage is also observable, information transmission becomes easier. Most of the time, then, but not always, the efficient contract deters (induces) entry against the low (high) cost incumbent.     

Optimal Pricing and Entry Rules When a Regulated Dominant Firm Faces a Competitive Fringe

In this paper, we study optimal regulation of a dominant firm facing an unregulated competitive fringe. First, assuming the size of the fringe is fixed, we demonstrate that the usual Ramsey Rule for second-best efficient pricing remains applicable in this context. We also examine the suitability of the Laspeyres price cap and show that it retains its desirable properties. This implies that regulators should continue to apply Laspeyres price cap regulation to the dominant firm after competition has materialized. Then, assuming that price and entry control are regulatory instruments, we characterize the efficient pricing and entry rules. We demonstrate that the free entry equilibrium number of firms will be excessive relative to the efficient number of firms, thereby providing a new Excess Entry Theorem. Finally, we suggest a modification of the Laspeyres price cap that can incentivize the regulated dominant firm to support efficient entry into the fringe.     

Takeover Contests, Toeholds and Deterrence

We consider a setting in which two potential buyers, one with a prior toehold and one without, compete in a takeover modeled as an ascending auction with participating costs. The toeholder is more aggressive during the takeover process because she is also a seller of her own shares. The non-toeholder anticipates this extra-aggressiveness of the toeholder. Thus, he is deterred from participating unless he has a high valuation for the target company. This leads to large inefficiency losses. For many configurations, expected target returns are first increasing then decreasing in the size of the toehold.     

Franchise Bidding Without Holdups: Utility Regulation with Efficient Pricing and Choice of Provider

The idea of franchise bidding, as a governance structure for regulating natural monopoly, has remained dormant for the last twenty years, during which the technology and regulation of natural monopoly has changed considerably, both in theory and in practice. Meanwhile, auction theory has advanced significantly, independently of regulatory economics, which has moved in a different direction, namely price-cap regulation. We seek to combine the effects of the changes in the technology of network industries and the advances in bidding theory and in regulatory economics toward the development of a rigorous model of franchise bidding. The model presented in this paper, which develops conditions for efficient outcomes, provides a benchmark to begin a reconsideration of the potential of franchise bidding. In particular, for the first time, we complete Demsetz' (1968) proposal by specifying (second-price) rules for bidding and for transfer of assets when the incumbent loses the bid at re-auction. The scheme features one bid determining simultaneously output pricing and asset transfer pricing, to address concerns of hold-up and opportunistic behavior in the event of a change in franchisee.
