Screening and signalling for technology licensing: a comparison

This article studies, in an adverse selection set‐up, how a patentee licenses a new technology in a two‐period context where the licensee has private information on its marginal cost of production. Two different ways of licensing are considered: the patentee offers, in the first period, either a menu of contracts that screens the different types of licensee or a single contract that obliges the licensee to signal its true type. Of these two contracts, the better for the patentee depends on the probability of the innovation gives rise to a low marginal cost and the difference between the high and low cost. Findings explain, to some degree, the variety of licensing contracts observed in practice (some including only a fixed fee, and others including both a royalty and a fixed fee). This variety may be rationalised by the use of different devices (signalling or screening) aimed at alleviating the effects of opportunism. A welfare comparison of the two means for extracting hidden information from the licensee is also made.     

VERTICAL RESTRAINTS UNDER ASYMMETRIC INFORMATION: ON THE ROLE OF PARTICIPATION CONSTRAINTS*

The impact on vertical contracting of a type‐dependent reservation utility is investigated within a sequential monopolies environment with asymmetric information. The welfare and private properties of contracts controlling both the retail price and the sales level are compared with those restricting only sales. When firms choose contracts non‐cooperatively, retail price restrictions are desirable for the upstream supplier although detrimental to consumers, whenever the retailer reservation utility has a relevant impact on optimal contracts. If this impact is relatively weak and contracts are chosen cooperatively, vertical price control fails to maximize firms' joint‐profit although it would be beneficial to consumers.     

Analyzing the Welfare Impacts of Full‐line Forcing Contracts

Theoretical investigations have examined both anti‐competitive and efficiency‐inducing rationales for vertical bundling, making empirical evidence important to understanding its welfare implications. We use an extensive dataset on full‐line forcing contracts between movie distributors and video retailers to empirically measure the impact of vertical bundling on welfare. We identify and measure three primary effects of full‐line forcing contracts: market coverage, leverage and efficiency. We find that bundling increases market coverage and efficiency, but has little impact on one distributor's gaining leverage over another. As a result, we estimate that full‐line forcing contracts increased consumer and producer surplus in this application.     

Long‐Lived Consumers,Intertemporal Bundling and Collusion

In a repeated price game with long but finitely‐lived consumers, long‐term contracts facilitate collusion. Intertemporal bundling reduces the gains from business stealing but has little effect on the cost of the resulting price war. When consumers anticipate future price wars, the maximum deviation profit is a single period of consumer surplus per consumer. Hence long‐term contracts do not increase the incentive to deviate per consumer, but do reduce the the number of consumers currently in the market by locking them into past contracts, so tacit collusion is sustainable for a wider range of discount factors and market structures.     

Anti-competitive effects of resale-below-cost laws

We show that resale-below-cost laws enable producers to impose industrywide price-floors to retailers. This mechanism suppresses downstream competition but also dampens upstream competition, leading to higher prices. Price-floor may be more profitable for producers than resale price maintenance contracts and, while resale price maintenance may have ambiguous effect on welfare, price-floors always harm welfare. Retailers' buyer power appears as a key element for a price-floor to work out.     

The Welfare Losses From Price-Matching PolicIes

Several recent papers argue that price-matching policies raise equilibrium prices. We add to this literature by considering potential welfare losses, which have two sources: Harberger triangles from high prices and Posner rectangles from over-entry. We compare price-matching markets with entry to monopoly and price-matching markets without entry, and find that price matching with entry creates greater welfare losses than monopoly in markets with a low ratio of fixed to marginal cost. We illustrate this result using parameters from the US wholesale gasoline and air travel markets, and relate our model to price matching among NASDAQ market makers.     

Vertical Contracts and Downstream Entry*

We study the implications of different contractual forms in a market with an incumbent upstream monopolist and free downstream entry. We show that traditional conclusions regarding the desirability of linear contracts radically change when entry in the downstream market is endogenous rather than exogenous. By triggering more entry than two-part tariffs, wholesale price contracts can generate higher aggregate output, consumer surplus, and welfare. In light of this, the upstream monopolist may prefer to trade with wholesale price contracts as well as to give up part of its bargaining power when it is high.     

Endogenous Average Cost Based Access Pricing

We analyze an endogenous average cost based access pricing rule, where both the regulated firm and its rivals realize the interdependence among their outputs and the regulated access price. In contrast, the existing literature on access pricing has always assumed that the access price is exogenously fixed ex-ante. We show that endogenous access pricing neutralizes the artificial cost advantage that is enjoyed by the incumbent firm. Further, endogenous access pricing results in a consumer surplus that is equal to or higher than that under exogenous access pricing. If the entrant is more efficient than the incumbent, then the welfare under endogenous access pricing is higher than that under exogenous access pricing.     

Costing fixed assets in Swedish municipalities: Effects of changing calculation methods

When pricing public utility services Swedish municipalities are not allowed to charge more than their full cost. A dominant cost component in operations such as energy distribution or handling water and wastewater is the cost of fixed assets—depreciation plus interest, here referred to as “capital service cost” (CSC). The maximum acceptable price for the services is the full cost, i.e., variable cost plus fixed cost, which is mainly CSC. For CSC the sum of the present values (PV) should not exceed the investment value. Several different CSC methods meet such a PV criterion but allocate the CSC differently over time. To achieve a better match with the generated services, costing practice has changed, shifting among several alternate CSC methods. As these alternates all meet the PV criterion, the issue of charging more than full cost has not been given much attention. However, it is not enough to focus on the internal consistency of the methods. The implementation of changes and the choice of parameter values, such as interest rates, have to be considered. Such wider analysis reveals that Swedish municipalities have overestimated the full costs in public utilities by a total of several tens of billions SEK (several billions USD) giving rise to a corresponding overcharge.     

The Year in Review: Economics at the Antitrust Division, 2006–2007

In this paper, we evaluate the scope of Chadwick’s claim on the superiority of competition for the market over competition in the market under incomplete information. We firstly characterize the expected outcome achieved under competition in the market at a Cournot Bayesian-Nash equilibrium. Then we characterize the optimal expected outcome achieved under a competition for the market mechanism designed by a government facing a shadow cost of public funds. We show that a regulated monopoly selected by an auction mechanism results in higher expected welfare than does duopoly competition when the entry cost is low but that the opposite holds when the market size is small and the entry cost is high for some values of the shadow cost of public funds. These results are explained by the influence of adverse selection on the entry decision at the Cournot equilibrium and by the level of expected total fixed costs in both mechanisms.      

Price Dispersion Over the Business Cycle: Evidence from the Airline Industry

This study provides empirical evidence documenting how price dispersion moves with the business cycle in the airline industry. Performing a fixed‐effects panel analysis on seventeen years of data covering two business cycles, we find that price dispersion is highly pro‐cyclical. This effect is especially pronounced for legacy carriers relative to low‐cost carriers. We show that our empirical result is consistent with firms' implementing second‐degree price‐discrimination tactics.     

Market failures and the additionality effects of public support to private R&D: Theory and empirical implications

We extend the theoretical basis of the empirical literature on the effects of R&D subsidies by providing an estimable model of strategic interaction among subsidy applicants, and public and private sector R&D financiers. Our model incorporates fixed R&D cost and a cost of external finance. We derive the optimal support rule. At the intensive (extensive) margin the costs of external funding reduce (increase) the optimal subsidy rate. We also establish necessary and sufficient conditions for the existence of additionality. It turns out that additionality at the intensive margin is less likely with higher spillovers. Our results suggest that the relationship between additionality and welfare may not be straightforward.     

VERTICAL INTEGRATION AND SHARED FACILITIES IN UNREGULATED INDUSTRIES

In this paper we analyze the equilibrium market structure, following liberalization, of an industry involving an essential facility. Two alternative modes of market entry are considered, in conjunction with vertical integration, namely: (i) full entry, which means building a new and more efficient facility at a positive fixed cost; and (ii) partial entry, which means purchasing existing capacity from the incumbent, at a fixed price per unit that is freely negotiated between the incumbent and the entrant. We show that vertical integration is a dominant strategy for each firm under either entry mode, and that upstream firms choose to share the incumbent's facility when the entrant's fixed cost exceeds a positive threshold. In addition, welfare analysis shows that in many situations the market can efficiently solve the trade-off between fixed-cost savings and softened downstream competition, thus providing a rationale for the liberalization of such industries. Several competition policy implications are discussed.     

AN ANALYSIS OF CONTRACT COST PHASING ON ENGINEERING AND CONSTRUCTION PROJECTS

The development and implementation of engineering and construction projects for new manufacturing facilities in the oil, gas, and petrochemical industry is largely contracted out. Progress and cost control by the owner is an intrinsic part of these projects. The results of an empirical analysis of payment and progress schedules for different contract types are presented, indicating a practice of advance payments on lump sum/fixed price contracts. The Value of Work Done concept and a normalized approximation function for progress control are discussed. The results provide guidance for progress management and contract cost phasing on engineering and construction projects.     

Price Dispersion in Mortgage Markets

Using transaction‐level data on Canadian mortgage contracts, we document an increase in the average discount negotiated off the posted price and in rate dispersion. Our aim is to identify the beneficiaries of discounting and to test whether dispersion is caused by price discrimination. The standard explanation for dispersion in credit markets is risk‐based pricing. Our contracts are guaranteed by government‐backed insurance, so risk cannot be the main factor. We find that lenders set prices that reflect consumer bargaining leverage, not just costs. The presence of dispersion implies a lack of competition, but our results show this to be consumer specific.     

Public pricing under imperfect competition

Existing literature on second-best pricing assumes that regulatory control encompasses all industries subject to distortion. This paper extends the theory in a game-theoretic framework to incorporate market power outside the regulated sector. We find that in this situation, price always exceeds marginal cost in the public firm and that the profit constraint for the public firm need not be binding. In addition, the existence of pricing distortions outside the regulated sector can actually increase welfare.     

Multilateral Vertical Contracting with an Alternative Supply: The Welfare Effects of a Ban on Price Discrimination

Rey and Tirole [Handbook of Industrial Organization. Amsterdam: Elsevier (2005)] considered a model in which a monopolist sells to downstream firms using nonlinear contracts. They showed that banning price discrimination fully restores the supplier’s ability to leverage its monopoly power by enabling it to commit not to offer side discounts. I show that the situation changes when the supplier competes against a fringe of less efficient rivals rather than being a monopolist. Then banning price discrimination may cause per-unit prices to fall and welfare to increase. The dominant supplier can take advantage of a strategic bargaining effect: reducing the per-unit price makes the outside option of buying from the fringe less profitable, allowing the dominant supplier to extract more bargaining surplus through the fixed fee.     

Optimal Selling Mechanism,Auction Discounts and Time on Market

This article examines the optimal selling mechanism problem in real estate market using mean‐variance analysis and downside risk analysis. When sellers can choose between accepting the first offer above a reservation price or auctions (waiting an optimal and fixed time), sellers having higher risk aversion choose auctions and wait a fixed time while sellers having lower risk aversion choose an optimal reservation price and wait a random time. Positive auction discounts are compensated by reduced risks, and there exists a connection between liquidity risk and conditional auction discount. More (Fewer) sellers will choose to sell their houses through auctions in a hot (cold) market or when holding cost increases (decreases). When sellers choose auctions, sellers having higher risk aversion who have lower holding cost wait longer and obtain higher sale price. Loss‐averse sellers unanimously choose the mechanism of setting an optimal reservation price.     

Differential Pricing in Intermediate Good Markets

This paper studies differential pricing by an upstream monopolist whose cost to supply the intermediate good differs across buyers in the downstream. It is shown that, different from demand‐based price discrimination, cost‐based differential pricing shifts production efficiently. If total output (and consumer welfare) is weakly increased under differential pricing as opposed to uniform pricing, as is true for weakly convex final market demand functions, social welfare is strictly improved. The analysis is extended to the case in which both the upstream monopolist's cost to serve the downstream firms and the downstream firms’ cost to produce the final good differ.     

Yardstick Competition to Elicit Private Information: An Empirical Analysis

The Japanese regulatory authority has introduced a new hybrid regulation that combines a fixed-price contract with ex ante yardstick inspection for local (public utility) gas distribution. The latter compares a firm??s reported costs with those of ??similar?? firms, and penalizes high-cost firms. We infer the effect of yardstick on information revelation by comparing the actual welfare level with the hypothetical full-information welfare level. Our results suggest that only the very first inspection was effective in reducing firms?? incentive to report higher costs.
