Abstract: | This paper constructs a model of anticompetitive exclusive dealing in the presence of multiple entrants. Unlike a single-entrant model in the extant literature, an entrant competes not only with the incumbent to deal with buyers but also with other entrants. The competition among entrants then plays the role of commitment such that low wholesale prices are offered to buyers when they deviate from exclusive contracts. We argue that this commitment effect becomes a barrier to exclusive dealing and that the results differ drastically from the predictions of the single-entrant framework. |

Abstract: | One of the most conspicuous features of mergers is that they come in waves that are correlated with increases in share prices and price/earnings ratios. We use a natural way to discriminate between pure stock market influences on firm decisions and other influences by examining merger patterns for both listed and unlisted firms. If "real" changes in the economy drive merger waves, as some neoclassical theories of mergers predict, both listed and unlisted firms should experience waves. We find significant differences between listed and unlisted firms as predicted by behavioral theories of merger waves. |

Abstract: | Retailer capacity decisions can impact sales for a product by affecting, for example, availability and visibility. Using data from the U.S. video rental industry, we report empirical estimates of the effect of capacity on sales. New monitoring technologies facilitated new supply contracts in this industry, which lowered the upfront cost of capacity and required minimum capacity purchases, thus strongly impacting stocking decisions. Under the traditional supply contract, capacity costs $44 per tape (avg) and the marginal tape produces 10.4 to 18.0 additional rentals. Under the new contract, capacity costs $7 per tape (avg) and the marginal tape produces 0 to 4.9 additional rentals. |

Abstract: | The impact of demand growth on the collusion possibilities is investigated in a Cournot supergame where market growth may trigger future entry and the collusive agreement is enforced by the most profitable grim trigger strategies available. It is shown that even in situations where perfect collusion can be sustained after entry, coping with a potential entrant in a market which is growing over time may completely undermine any pre-entry collusive plans of the incumbent firms. This is because, before entry, a deviation and the following punishment phase may become more attractive thanks to their additional effect in terms of delaying entry. |

Abstract: | To explore the efficacy of a corporate leniency program, a Markov process is constructed which models the stochastic formation and demise of cartels. Cartels are born when given the opportunity and market conditions are right, while cartels die because of internal collapse or they are caught and convicted by the antitrust authority. The likelihood that a cartel, once identified, is convicted depends inversely on the caseload of the antitrust authority due to an implicit resource constraint. The authority also chooses an enforcement policy in terms of the fraction of non-leniency cases that it prosecutes. Using numerical analysis, the impact of a leniency program on the steady-state cartel rate is investigated. Holding the enforcement policy of the antitrust authority fixed, a leniency program lowers the frequency of cartels. However, the additional caseload provided by the leniency program induces the antitrust authority to prosecute a smaller fraction of cartel cases identified outside of the program. Because of this less aggressive enforcement policy, it is possible that the cartel rate is higher when there is a leniency program. |

Abstract: | Some retail markets are more competitive than others. A manufacturer with market power in the wholesale market who sells his product to competing retailers in cities and monopolistic ones in each of various towns must set the wholesale price difference between towns and cities to be smaller than the transportation cost to prevent “grey market” arbitrage. If he uses linear pricing, the town retail price will be even higher than under single-retailer double marginalization. Two-part tariffs do not solve the problem as they would if there were a single retailer, because the wholesale unit price must be higher than marginal cost to prevent arbitrage to the cities. If transportation costs are low, price discrimination is difficult and two- part tariffs come to resemble inefficient linear monopoly pricing. High transportation costs allow greater efficiency in contracting, and this can outweigh the negative direct effect on welfare. |

Abstract: | The English auction is susceptible to tacit collusion when post-auction inter-bidder resale is allowed. We show this by constructing equilibria where, with positive probability, one bidder wins the auction without any competition and divides the spoils by optimally reselling the good to the other bidders. These equilibria interim Pareto dominate (among bidders) the standard value-bidding equilibrium, without requiring the bidders to make any commitment on bidding behavior or post-bidding spoil-division. |

Abstract: | Barriers to entry are regarded as major impediments to the working of markets. Entry must not necessarily actually take place - the perceived threat of entry may encourage incumbent firms to behave as if they are in a competitive market, even if they are not. We present empirical evidence on effects of perceived threat of entry on profitability. Using information from managers about how they assess the existence of entry barriers a strong impact of these assessments on profitability is confirmed. The number and the relative size of competitors also exert considerable effects. We find no statistically significant relation between the perceived threat of entry and the actual number of firms if the size of the relevant market is taken into account. |

Abstract: | A wider RJV extension hastens process innovations at the cost of increasing collusion in the final market. In a Cournot model, an extended RJV is welfare enhancing only when the Antitrust Authority is strong, so that the increase in distortion is limited, and when the size of the technical improvement is large, so that the introduction of the innovation is more valuable. |

Abstract: | Theory predicts a positive relationship between market concentration and profitability in most scenarios. In empirical work, however, this relation is frequently not found or only a weak connection is observed. We compare the performance of concentration and market share variables, which are generated on the basis of the official industry classification, with information collected directly from firms. Information from companies on the number of competitors, their relative size and the intensity of price competition is highly significant in explaining profit levels, while none of the concentration indices performs well. Hence, the poor quality of industry data is responsible for the loose connection that is usually found between concentration and profitability. |

Abstract: | In the reputation model of Klein and Leffler (1981) firms refrain from cutting quality or price because if they did they would forfeit future profits. Something similar can happen even in a static setting. First, if there exist some discerning consumers who can observe quality, firms wish to retain their purchases. Second, if all consumers can sometimes but not always spot flaws, firms do not want to lose the business of those who would spot them on a given visit. Third, if the law provides a penalty for fraud, but not one so high as to to make fraud unprofitable, firms may prefer selling high quality at high prices to low quality at high prices plus some chance of punishment. |

Abstract: | We analyse incentives for collusive behaviour when heterogeneous providers are faced with regulated prices under two forms of yardstick competition, namely discriminatory and uniform schemes. Providers are heterogeneous in the degree to which their interests correspond to those of the regulator, with close correspondence labelled altruism. Deviation of interests may arise as a result of de-nationalisation or when private providers enter predominantly public markets. We assess how provider strategies and incentives to collude relate to provider characteristics and across different market structures. We differentiate between “pure” markets with either only self-interested providers or with only altruistic providers and “pluralistic” markets with a mix of provider type. We find that the incentive for collusion under a discriminatory scheme increases in the degree to which markets are self-interested whereas under a uniform scheme the likelihood increases in the degree of provider homogeneity. Providers’ choice of cost also depends on the yardstick scheme and market structure. In general, costs are higher under the uniform scheme, reflecting its weaker incentives. In a pluralistic market under the discriminatory scheme each provider’s choice of cost is decreasing in the degree of the other provider’s altruism, so a self-interested provider will operate at a lower cost than an altruistic provider. Under the uniform scheme providers always choose to operate at the same cost. The prospect of defection serves to moderate the chosen level of operating cost. |

Abstract: | This paper addresses the reduction of market failure under imperfect competition. It proposes a taxscheme that provides firms with an incentive to forgo their market power: Firms optimize after-tax profits. Now simply consider a firm´s gross profit margin the unique tax-rate it is charged on absolute profits. In theory the firm´s tax-rate would be the mark-up over marginal costs, the firm´s Lerner index. As a result every firm determines its own tax-rate by setting its price and incurring costs. This creates a new trade off for firms between a low tax-burden and the exercising of market power. Welfare for society increases since firms with market power choose a lower price and produce a quantity closer or equal to social optimum; at the original monopolistic price-level they can increase their profits by lowering their tax-burden. Essentially the tax-condition does not seem to distort profit incentives or markets; under perfect competition the tax-rate would be zero. Thus, it is clear that the tax only takes effect when markets work inefficiently and its countervailing nature subsequently helps to remedy inefficiencies of imperfectly competitive markets. |

Abstract: | The Dixit-Stiglitz model is extended by the possibility for rms to un- dertake process innovation. The model can provide a new explanation to describe the relationship that research activity of rms is positively corre- lated with product market competition at low levels of competition, and negatively at high levels that has been found in the data. The initial pos- itive relationship is caused by an increased business stealing opportunity with more competition, while the negative eect comes from the reduc- tion of the markup due to higher competition (measured as elasticity of substitution). Also the ambiguous relationship of market entry barriers with respect to research activity is discussed using a less general form of the model. This framework may also be used to explain the inverted-U relationship found between competition and advertising expenditures. |

Abstract: | This paper analyses the impact of loan market competition on the interest rates applied by euro area banks to loans and deposits during the 1994-2004 period, using a novel measure of competition called the Boone indicator. We find evidence that stronger competition implies significantly lower spreads between bank and market interest rates for most loan market products. Using an error correction model (ECM) approach to measure the effect of competition on the pass-through of market rates to bank interest rates, we likewise find that banks tend to price their loans more in accordance with the market in countries where competitive pressures are stronger. Further, where loan market competition is stronger, we observe larger bank spreads (implying lower bank interest rates) on current account and time deposits. This would suggest that the competitive pressure is heavier in the loan market than in the deposit markets, so that banks compensate for their reduction in loan market income by lowering their deposit rates. We observe also that bank interest ratesin more competitive markets respond more strongly to changes in market interest rates. These findings have important monetary policy implications, as they suggest that measures to enhance competition in the European banking sector will tend to render the monetary policy transmission mechanism more effective. |

Abstract: | We analyze the incentives of a telecommunications incumbent to invest and give access to a downstream entrant to a next generation network, NGN. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network, compete on Hotelling's line. The incumbent can invest in the deployment of a NGN that improves the quality of the retail services. Access to the old network is regulated, but access to the NGN is not. If the innovation is drastic, the incumbent always invests in the NGN, but does not give access to the entrant. If the innovation is non-drastic and if the access price to the old network is low, the incumbent voluntarily gives access to the NGN. If the innovation is non-drastic, there is no monotonic relation between the access price to the old network and the incumbent's incentives to invest. A regulatory moratorium emerges as socially optimal, if the innovation is large but non-drastic. We also analyze the case where both firms can invest in the deployment of a NGN. |

Abstract: | In this paper we analyze the effects of changing market structure on price dynamics of final goods in the emerging Czech retail market. We estimate the extent of upstream and downstream market power and find that changing market structure was responsible for an average yearly decrease in the prices of retailed products of 0.8 p.p. during 2000–2005. At the same time, however, we anticipate that the already started period of mergers and acquisitions could cause yearly increases in the prices of retailed products of 1.2 p.p. (approximately 0.5 p.p. in the CPI) over the next ten years. |

Abstract: | We develop a simple model of competition for the market that shows that, contrary to the Arrow view, endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions with a Tobit model based on a unique dataset and survey for the German manufacturing sector (the Mannheim Innovation Panel). We confirm the empirical validity of our predictions and perform a number of robustness test with instrumental variables. |

Abstract: | A group of small competitive permits traders facing an imperfectly competitive permit market may consider cooperation (merger) to act strategically in the permit market. It is a well-known result in the literature that the horizontal merger of Cournot players may be unprofitable because of the response of nonmerging agents (a negative strategic effect). We show that the strategic effect of a merger among competitive agents substantially differs from the strategic effect of a merger among Cournot players. Furthermore, we show how the profitability of a merger depends on whether the merged agents are on the same side of the market as the preexisting dominant agent(s). These results show how the expected competitive environment in the permit market may determine how potentially large traders such as the US, and group of small, competitive traders, such as the EU countries, organize their permit trade in any follow-up agreement to the Kyoto protocol. |

Abstract: | We examine an incumbent?s trade-o¤ between expanding her business, which increases her pro?ts, and the information that such expansion signals to potential competitors, which attracts them to the market. Speci?cally, we consider a signaling game where the incumbent knows the actual realization of demand, whereas the entrant can only observe whether the incumbent de- cided to expand the size of her business in the past. In particular, we analyze the set of pooling and separating equilibria surviving the intuitive criterion in this signaling model. Our predic- tions can support the expected observation that only incumbents in good market conditions expand their businesses (separating equilibria), but also the less obvious and interesting pooling equilibria in which no ?rm expands her business, and despite such non-expansion entrants choose to enter the industry. This equilibrium result helps us provide an explanation about the high failure rates that new ?rms face when entering a market, as con?rmed by multiple empirical studies. |

Abstract: | This paper uses firm-level data from the Business Environment and Enterprise Performance Surveys (BEEPS) to study the process of convergence of transition countries with developed market economies. The primary focus of the study is on competition and market structure, finance and the structure of lending to firms, and how firms respond to the economic environment by restructuring; we are able to do this because the BEEPS cover thousands of firms from virtually all transition countries over a long time period (1996-99 through 2002-05), as well firms from developed market economies, thus providing a set of natural benchmarks. We find substantial evidence of convergence of transition countries with developed market economies in a number of dimensions. The pattern of growth at the country, sectoral and firm level shows rapid growth of the new private sector and of the micro- and small-firm sectors, with the size distribution of firms moving towards the pattern observed in the BEEPS surveys of developed market economies. Our interpretation of the evidence on competition is that there is an initial move by firms into niches to exploit local market power, and later in transition entry and domestic competitive pressure increases. In finance, the increasing reliance on retained earnings in transition countries reflects a maturation of the sector as new firms come to rely less on informal and family sources of finance. The scale of restructuring and innovation activity is as high or higher in transition economies as in developed market economies. Interestingly, we find evidence of an inverse-U shape pattern, with the peak of restructuring activity taking place in 2002, the middle of the period analyzed. Throughout, the regional patterns suggest greater convergence in the transition countries that joined the European Union in 2004 than in the other, lower-income transition economies. |

Abstract: | The electricity spot markets can be considered as capacity constrained markets (Kreps and Scheinkman, 1983), where market price definition depends on the quantity strategies. In this theoretical framework, the main target of the present paper is to show to what extent a spot market organized like a Uniform Price Auction (UPA) is naturally inclined to develop anti-competitive practices, in particular through quantity strategies. To achieve this objective, multivariable models are defined for each daily demand period of the Iberian electricity market. Each model correlates the hourly market price change and the bid quantities of the two main Iberian producers (Endesa and Iberdrola), for every summer between 2001 and 2004. To apply those models one has to solve the endogeneity problem. This exercise is also useful to highlight any anti-competitive behaviour. Quantities produced by the producers with infra marginal bids should not be endogenous when there is no risk that they will not be dispatched, unless producers have some expectations about the system marginal price. In addition, this kind of endogeneity reinforces the model’s theoretical assumption that change in the system marginal price stems from quantity strategies. The models present some expectable but interesting results. Those results show that even base load units’ bids may depend on expectations about the system marginal price evolution. Those expectations can reflect market strategies. Therefore, in a market where the main companies own base load and peak load units, like the Iberian wholesale electricity market, the UPA is an open window to anti-competitive practices based on quantity strategies, such as the raising of the system marginal price through the capacity withdrawal from base load units. |

Abstract: | We consider a dynamic homogenous oligopoly in which firms set prices repeatedly. Theory predicts that short-run price commitments have an increasing impact on profits and may lead to less price stability. The experiments that we conduct provide support for the first effect and against the second effect when a random ending rule is applied. Application of a fixed ending rule seems to reverse these findings, but none of the effects is significant. |

Abstract: | This paper explores network effects in Point-to-Point airline networks by examining the spatial entry patterns of Southwest airlines during the 1990-2006 period. Estimation results from a spatial probit model reveal clear spatial dependence in profitability across different routes served by the carrier. Detailed investigation suggests two main sources of network effects, namely: (1) airport and regional presence, and (2) substitutability of markets. Findings of the paper suggest also that the network effects embedded in Southwest’s Point-to-Point network have many distinguishing features as compared to those identified in a typical Hub-and-Spoke network. This study brings some fresh insights on airline network effects in general, as well as explaining the pattern of aggressive network expansions of LCCs in particular. |

Abstract: | This paper proposes a model for a certification market with an imperfect testing technology. Such a technology only assures that whenever two products are tested the higher quality product is more likely to pass than the lower quality one.When only one certifier with such testing technology is present in the market, it is found that this monopoly certifier can be completely ignored in equilibrium, in contrast to the prediction of a model with perfect testing technology. A separating equilibrium is also supported in which only relatively high quality types (products) choose to pay for the certification service. It is true that in such an equilibrium having a certificate is better than not. The exact value of a certificate, however, depends both on the prior distribution of product quality and the nature of the testing technology.Welfare accounting shows that the monopolistic certifier’s profit maximizing conduct can lead to under or over supply of certification service depending on model specification. Optimal certification fee is always positive and such that it makes all positive types choose to test. In the case of two competing certifiers with identical testing technologies, the intuition of Bertrand competition does not necessarily hold. Segmentation equilibrium in which higher seller types choose the more expensive certification service and not so high types choose the less expensive service can be supported. As an application, we argue that the fee differentiation between major and non-major auditing firms need not be a result of any differences in their auditing technologies. |

Abstract: | An extensive theoretical literature on bundling examines its potential efficiency and anti-competitive effects. In this paper, we provide an empirical study of bundling in a supply chain, referred to as full-line forcing. Using an extensive dataset on contracts between video retailers and movie distributors, we identify and measure three effects of full-line forcing: market coverage, leverage, and efficiency. We estimate a structural model of demand and the cost of holding inventory. Using the estimated parameters, we examine the effects of delaying the introduction of full-line forcing contracts. We find that delay results in a welfare loss for firms and consumers. |

Abstract: | This paper modifies the optimal penalty analysis by incorporating investment incentives with external benefits. In the models examined, the recommendation that the optimal penalty should internalize the marginal social harm is no longer valid as a general rule. We focus on antitrust applications. In light of the benefits from innovation, the optimal policy will punish monopolizing firms more leniently than suggested in the standard static model. It may be optimal not to punish the monopolizing firm at all, or to reward the firm rather than punish it. We examine the precise balance between penalty and reward in the optimal punishment scheme. |

Abstract: | We develop a competitive pricing model which combines the complexity of time-varying demand and cost functions and that of scale economies arising from dynamic lot sizing costs. Each firm can replenish inventory in each of the T periods into which the planing horizon is partitioned. Fixed as well as variable procurement costs are incurred for each procurement order, along with inventory carrying costs. Each firm adopts, at the beginning of the planning horizon, a (single) price to be employed throughout the horizon. Based on each period's system of demand equations, these prices determine a time series of demands for each firm, which needs to service them with an optimal corresponding dynamic lot sizing plan. We establish the existence of a price equilibrium and associated optimal dynamic lotsizing plans, under mild conditions and employing a close approximation for the optimal lotsizing costs. We also design efficient procedures to compute the equilibrium prices and dynamic lotsizing plans. |

Abstract: | Is it better to move first, or second— to innovate, or to imitate? We look at this in a context with both asymmetric information and payoff externalities. Suppose two players, one with superior information about market quality, consider entering one of two new markets immediately or waiting until the last possible date. We show that the more accurate the informed player’s information, the more he wants to delay to keep his information private. The less-informed player also wants to delay, but in order to learn. The less accurate the informed player’s information, the more both players want to move first to foreclose a market. More accurate information can lead to inefficiency by increasing the players’ incentive to delay. Thus, a moderate delay cost can increase industry profits. |

Abstract: | The recent expansion of Low Cost Carriers (LCCs) and the increasing use of Internet are provoking a deep transformation in the marketing of the typical Mediterranean summer tourism product in Europe. Internet may significantly reduce intermediary costs by enabling the connection between accommodation and transport business and consumers. At the same time, a more flexible product can be created in contrast to the conventional rigid tourist package offered by traditional tour operators. This paper investigates differences in price level and price dispersion across off-line and on-line markets and across tour operators and new emerging Internet retailers -including LCCs- using microdata on travel & accommodation individual expenses of tourists in the Balearic Islands, one of the most representative mature Mediterranean resorts. On the basis of the hedonic regression model, results suggest that price of transport; accommodation and board offered on Internet are lower than those offered by others channels, whatever the quality and quantity. Additionally, results reveal how on-line and off-line markets differ in the indirect value attributed to different characteristics of the product showing market segmentation. |

Abstract: | We study how fragmentation of patent rights ('patent thickets') and the formation of theCourt of Appeal for the Federal Circuit (CAFC) affected the duration of patent disputes, andthus the speed of technology diffusion through licensing. We develop a model of patentlitigation which predicts faster settlement agreements when patent rights are fragmented andwhen there is less uncertainty about court outcomes, as was associated with the 'pro-patentshift' of CAFC. The model also predicts that the impact of fragmentation on settlementduration should be smaller under CAFC. We confirm these predictions empirically using adataset that covers nearly all patent suits in U.S. federal district courts during the period1975-2000. Finally, we analyze how fragmentation affects total settlement delay, taking intoaccount both reduction in duration per dispute and the increase in the number of requiredpatent negotiations associated with patent thickets. |

Abstract: | We study entry and bidding patterns in sealed bid and open auctions with heterogeneous bidders. Using data from U.S. Forest Service timber auctions, we document a set of systematic effects of auction format: sealed bid auctions attract more small bidders, shift the allocation towards these bidders, and can also generate higher revenue. We show that a private value auction model with endogenous participation can account for these qualitative effects of auction format. We estimate the model's parameters and show that it can explain the quantitative effects as well. Finally, we use the model to provide an assessment of bidder competitiveness, which has important consequences for auction choice. |

Abstract: | Entry into an industry often clusters in regions where the industry is already concentrated, which is suggestive of agglomeration economies. Regional public research activities may exert another attracting force on entrants into science-based industries. Empirically these proximity effects are confounded by other influences on where entrants originate and locate. This paper begins to disentangle the effects of agglomeration, public research, and the supply of capable entrants for the German laser industry. Our findings indicate that the industry’s geography was shaped by the local availability of potential entrants rather than localization economies. The impact of public research increased over time. |
