Market Mechanism Choice and Real Estate Disposition: Search Versus Auction

We propose a model of mechanism choice in the disposition of real estate assets where we consider two alternatives: a search market and an auction. Within the search framework, we derive an equilibrium whereby buyers incur search costs and sellers incur holding costs for the period during which the property is not sold. In the auction alternative, the seller joins an existing pool of sellers in undertaking a multiple–object auction and pays a commission upon sale. Buyers and sellers freely choose their mechanisms, which in equilibrium are optimal given each group's conjectures about the mechanism choice of their counterpart. In equilibrium, an agent cannot benefit from deviating from his choice and each agent's beliefs are consistent with the equilibrium outcome. It is shown that (a) buyers with high search costs will choose auctions because the auction payoff imposes an upper bound on buyers' gains from search, and (b) prices at auctions will be higher. Using vacant lot sales data and a method–of–moment estimator which accounts for the presence of an endogenous discrete mechanism choice variable, we estimated a hedonic regression to detect the price effect. It was determined that, on average, lots sold for $1.44 per square foot more in auctions than in the search market, as predicted by our model.     

Tying in Two‐Sided Markets with Multi‐Homing: Corrigendum and Comment

We identify two issues in Choi's [2010] paper on tying in two‐sided markets published in this Journal, and provide solutions to both of them. First, we point out that the equilibrium in the absence of tying requires more restrictive conditions and does not satisfy a natural equilibrium refinement criterion. We offer an alternative timing structure that validates the equilibrium derived in Choi [2010] under the conditions provided there. Second, we show that his equilibrium analysis with tying ignores a profitable deviation. We rectify this analysis under our alternative timing structure and derive the (mixed‐strategy) equilibrium with tying. We also show by means of simulations that tying is welfare‐enhancing whenever it is profitable, which is consistent with the main finding in Choi [2010].     

Entry and product quality under price regulation

Spence (1975, footnote 5, p. 420) has shown that, in equilibrium, a price-regulated monopoly will supply a socially suboptimal level of quality. This tendency to undersupply quality has been used to justify an expansion of regulatory controls to the quality dimension in certain regulated industries (e.g., electricity and telecommunications). In this paper, we examine the effects of entry on equilibrium product quality in an industry which is price-regulated. A generalized conjectural variation model is used which allows both monopolistic and oligopolistic market structures. Using this model, we find that regulation generally leads to a socially nonoptimal (either too high or too low) level of quality, where the direction of the resulting departure from optimal quality depends upon the conjectures that firms form. Spence's result is obtained as a special case. We then demonstrate that a policy that encourages (or, at least, does not discourage) entry into the regulated market will cause equilibrium quality to move in a social-welfare-improving direction, regardless of the direction of the original distortion.     

Competition‐driven repositioning

We study competition as an impetus for firms to reposition—to abandon their current positioning strategy and adopt a new one. We predict that as a strong firm moves closer, competition erodes the profitability of situated firms and prompts them to reposition. We expect this effect is pronounced the greater difference in competitive strength. However, we expect that countervailing forces exist such that the viability of alternative positions and the opportunity cost of abandoning a current position mitigate this effect. Evidence from a natural experiment in China's satellite television industry supports our hypotheses. This research adds to the existing literature on repositioning, which emphasizes the phenomenon as opportunity‐driven, and to the competitive interaction literature, which typically does not distinguish between noncounterattack strategies.

Winning us with trifles: Adverse selection in the use of philanthropy as insurance

Research Summary: We study the use of corporate philanthropy as a form of reputation insurance, developing a formal model of such insurance to examine how the terms of insurance in equilibrium change under different assumptions about the firm and its stakeholders. We then test the predictions from this model in the U.S. petroleum industry and find that philanthropic donations offer insurance‐like benefits, but are also positively associated with subsequent oil spills—firms that give more, spill more—with this association being stronger for spills that are under firms’ control and in states with low civic capacity. These results are consistent with an adverse selection/moral hazard equilibrium and suggest that the use of philanthropy as reputation insurance may benefit firms at the cost of society. Managerial Summary: Firms that donate to social causes develop a reputation for being socially responsible, and are often given the benefit of doubt when negative information about them comes to light. But are philanthropic firms truly more responsible? We argue that firms that donate more may be more likely to do harm—those that expect to do harm later are likely to give more now, and those that know their reputation protects them may become less careful. Evidence from the U.S. petroleum industry is consistent with this argument, with firms that give more having more subsequent oil spills, but only the type of spills that are under the firm's control, and only in states where the firm faces weaker scrutiny.     

Heterogeneous switching costs

We consider a two period model where consumers have different switching costs. Before the market opens an Incumbent sells to all consumers; after the market opens competitors appear. We identify the equilibrium both with Stackelberg and Bertrand competition and show how the presence of low switching cost consumers benefits the Incumbent, despite the fact that it never sells to any of them. Furthermore, we identify a free rider effect among consumers.     

INCENTIVES,EQUALITY AND CONTRACT RENEGOTIATIONS: THEORY AND EVIDENCE IN THE CHINESE BANKING INDUSTRY*

Renegotiation plays an important role in contract theory, but the empirical study of renegotiation is almost non‐existent in the literature. Using a unique dataset from the Chinese banking industry, we find that the large majority of managerial incentive contracts are renegotiated after performances are realized. We develop a model of contract renegotiation where supervisors and managers sign incentive contracts and then renegotiate them. In the unique equilibrium of the model, incentive contracts are almost always renegotiated ex post. Even though renegotiation is fully anticipated, incentive contracts affect performance. The predictions of the model find strong support from our empirical results.     

Testing a Behavioral Theory Model of Labor Negotiations

The Behavioral Theory we have developed stands up well and helps us gain a better feeling for the behavioral dynamics of collective bargaining. As expected, economic variables such as bargaining power and the estimated cost and probability of a work stoppage are important determinants of bargaining behavior. Nevertheless, the variables have a differential effect on bargaining goals, with strong bargaining power and low probability of a strike contributing to both distributive and integrative bargaining, whereas high expected costs of a strike help to persuade constituents to support their negotiators (intraorganizational bargaining). Thus we see the roie of intraorganizational bargaining as an alternative to being able to obtain a better settlement from the opponents. Attitudinal structuring seems to be more closely tied to integrative bargaining than was indicated by Walton and McKersie. Furthermore, there seems to be less direct conflict between the tactics used in integrative bargaining and those used in distributive bargaining than predicted by theory. Perhaps the mixed nature of most bargaining keeps the majority of negotiators from applying all-out distributive tactics. At any rate, strong bargaining power, constructive relationships, clear and specific statements of issues, as well as exploring them in a noncommital fashion, seem to aid both distributive and integrative bargaining. We uncovered a number of relationships which varied significantly according to the side (labor or management) and/or team role (chief negotiator or other team member) of the respondent. Although we feel they should be included in the theory of bargaining as moderator variables, and have thus included them in our model, we have only hinted at their impact in this paper. Overall, bargaining behavior and conditions seem to have as much effect on bargaining success as do the economic variables. Of course, we did not measure every possible economic variable, but neither did we examine all possible tactics. Our study confirms that collective bargaining is an interpersonal, attitudinal process as well as an economic one and that there are several distinct goals for the process. We have also demonstrated that, despite problems of locating current negotiations and obtaining an adequate rate of response, field study of the behavioral aspects of collective bargaining is feasible. We hope that investigations along this line will continue.     

Grantbacks,territorial restraints,and innovation

We analyse the effect of grantback clauses in licensing contracts. While competition authorities fear that grantback clauses might decrease the licensee's ex post incentives to innovate, a standard defence is that grantback clauses are required for the patent-owner to agree to license its technology in the first place. We examine the validity of this “but for” defence and the equilibrium effect of grantback clauses on the innovation incentives of the licensee for both non-severable and severable innovations, which roughly correspond to infringing and non-infringing innovations. We show that grantback clauses do not increase the patent-holder's incentives to license when non-severable innovations are at stake but they do when severable innovations are concerned – suggesting that the “but for” defence might be valid for severable innovations but not for non-severable ones, in direct contradiction to regulation in some jurisdictions. Moreover we show that, for severable innovations, grantback clauses can increase the range of parameters for which follow-on innovation by the licensee occurs. Our work extends the large literature on sequential innovation to an environment where information diffuses through licensing rather than through the mere act of patenting. In this different informational set up we show that Green and Scotchmer (1995)’s conclusion that the initial innovator should have a patent of infinite breadth no longer holds.     

Non-Exclusive Dealing with Retailer Differentiation and Market Penetration

Retailer differentiation exists in most industries and gives manufacturers an incentive to contract with different retailers to penetrate a market. This paper analyzes the impact of this penetration effect on vertical contract exclusivity in an oligopolistic model with differentiated retailers. In the model, manufacturers endogenously choose contract types and negotiate with retailers on wholesale prices. We show that, when the penetration effect is sufficiently strong, non-exclusive contracts lead to higher profits for the manufacturers and retailers. The model is applied to an example with logit demand, which shows that both manufacturers choosing the non-exclusive contracts is a dominant-strategy Nash equilibrium even though they may both be better off under exclusive contracts when the products have high quality or low costs.     

Impact of loss aversion on the newsvendor game with product substitution

This paper studies a newsvendor game in which two substitutable products are sold by two different retailers (newsvendors) with loss-averse preferences. Each loss-averse retailer facing stochastic customer demand and deterministic substitution rate will make an order quantity decision to maximize his expected utility. Since product substitution causes two retailers to make decisions in a competitive environment, game theory is used to find the retailers' optimal order quantities. It is shown that under certain conditions, there exists a unique Nash equilibrium in the newsvendor game. Under a symmetry assumption, each retailer's equilibrium order quantity is decreasing in the loss aversion coefficient and increasing in the substitution rate. Further, if the effect of loss aversion on the order quantity is strong enough to dominate the effect of competition, the total inventory level of a decentralized supply chain will be lower than that of a centralized supply chain. Numerical experiments are conducted to illustrate our results.     

A partial identification framework for dynamic games

Empirical work on strategic interactions is often subject to the critique that equilibrium selection assumptions drive the results. We develop a framework for partially identifying parameters of dynamic games without equilibrium selection assumptions. Our framework relies on incentive compatibility constraints that incorporate game theoretical results on equilibrium payoff sets to bound the unknown continuation payoffs. We apply this framework to identify cost parameters in three dynamic games where collusion is a potential outcome. The identified set demonstrates the ease of sustaining collusion with patient firms, in low demand and when monitoring is perfect, and can also be used to detect collusion.     

Buyer power and exclusion in vertically related markets

Suppliers and consumer organizations have become increasingly concerned by the build-up of buyer power of retailers in many markets. A major concern is that strong retailers will abuse their power to exclude products and rival retailers from the market to be able to increase prices to consumers. As a consequence, remedies to limit buyer power are discussed and implemented in many countries. In this paper we compare the incentives for exclusion, and the effect on consumers prices, under both buyer and seller power. We study a model with a dominant upstream manufacturer and a competitive fringe of producers offering their products to two differentiated downstream retailers. We compare the equilibrium outcome of this model when i) the dominant supplier holds all the bargaining power, and (ii) the retailers have all the bargaining power. We show that full or partial exclusion of either the competitive product or downstream retailers occurs when inter and intrabrand competition are strong. This is true both under seller and buyer power. However, in contrast to the received literature, we find that buyer power weakly enhances welfare compared to seller power because buyer power will lead to both more product variety (less exclusion) and lower retail prices.     

Creating balance in dynamic competitions

We consider incentives for organizing competitions in multiple rounds, focusing on situations where there is heterogeneity among the contestants ex ante, which discourages effort in a single contest. Heterogeneity evolves across rounds depending upon the outcomes of previous rounds. We present conditions under which balance in such a competition can be created, by determining the number of rounds and dividing the prize fund carefully across them, so that full rent dissipation entails. In the model, each round is an all-pay auction where contestants differ in their abilities to gain a momentum from winning. We also discuss the case when negative prizes are feasible, demonstrating that this strengthens the full dissipation result; and we consider a case where the size of the winner’s momentum is related to the size of the prize attained, showing that the stronger this linkage, the less of the prize is awarded early on.     

Policy risk,strategic decisions and contagion effects: Firm‐specific considerations

Research summary : In this article, we investigate the firm‐specific environment and its impact on firm strategy focusing on adverse changes in the policy environment and their effect on divestitures. We argue that experiencing a negative change in the firm‐specific policy environment causes firms to reassess their exposure to policy risk and their ability to manage their policy environment, making them more likely to divest. Operationalizing negative shifts in the firm‐specific policy environment through formal policy disputes between firms and governments, we find that following a dispute, firms are more likely to divest both in the country where the dispute occurs and in other countries in the same region. However, the impact of disputes on divestitures is firm specific, applying only to firms directly involved in a dispute . Managerial summary : What is the impact of change in the firm‐specific environment on firm strategy? We argue that when firms directly experience a negative change in their policy environment that is specific to them, they negatively reassess their exposure to policy risk and their ability to manage their policy environment, which makes them more likely to undertake a divestiture. We analyze formal disputes between firms and governments that arise from adverse changes in policy and find that, following a dispute, firms are more likely to divest in the country where the dispute occurs and in other countries in the same region. However, the impact of disputes on divestitures is firm specific as it applies only to firms directly involved in a dispute . Copyright © 2016 John Wiley & Sons, Ltd.     

Convenient flight connections vs. airport congestion: Modeling the ‘rolling hub’

This paper provides the first analysis of the trade-off between convenient flight connections and airport congestion, a fundamental but untreated element in the economics of hub-and-spoke networks. A continuous spatial model illustrates this trade-off in a framework where a small gap between flight operating times raises congestion while also shortening a connecting passenger’s layover time. When the passenger’s cost per unit of layover time rises, the monopoly airline chooses to narrow the gap between its flights, yielding shorter layovers but more congestion. A discrete spatial model, where flights congest one another only if they operate in the same discrete period, makes this layover-cost effect discontinuous: the monopoly carrier concentrates (deconcentrates) its flights when this cost is high (low) relative to the costs of congestion. When fringe carriers are present, however, the hub carrier always concentrates its flights, either partially or fully. But the presence of a second hub carrier leads to an equilibrium mirroring the monopoly outcome: the carriers concentrate their flights in different periods when the layover cost is high and deconcentrate them otherwise. The paper also presents a welfare analysis, showing that movement from the equilibrium to the social optimum typically requires greater carrier separation.     

Durable goods oligopoly

This paper models a durable-goods oligopoly as a differential game. Two cases are treated: sales, where firms cannot lease but must sell the good in question, and leasing, where firms do not sell but only rent. In the sales case, firms face increasing marginal cost of production and the good in question depreciates. For this case, a rational expectations feedback Nash equilibrium is constructed for which monopoly or oligopoly output is less than the efficient level. This gap between oligopoly and competitive output diminishes as the number of firms increases. When firms can only lease the good, the good is assumed not to depreciate and the monopoly level of steady state output is compared with the level of steady state output for a feedback equilibrium duopoly. For this case, the duopoly equilibrium has steady-state output that is less than the corresponding efficient level, but greater than the monopoly level. The leasing model is shown to be isomorphic to the adjustment-cost duopoly model of Driskill and McCafferty (Journal of Economic Theory, 49 (1989) 324–338).     

Supply function equilibria with capacity constraints and pivotal suppliers

The concept of a supply function equilibrium (SFE) has been widely used to model generators' bidding behavior and market power issues in wholesale electricity markets. Observers of electricity markets have noted how generation capacity constraints may contribute to market power of generation firms. If a generation firm's rivals are capacity constrained then the firm may be pivotal; that is, the firm could substantially raise the market price by unilaterally withholding output. However the SFE literature has not fully considered the impact of capacity constraints and pivotal firms on equilibrium predictions. We characterize the set of symmetric supply function equilibria for uniform-price auctions when firms are capacity constrained and show that this set is increasing as capacity per firm rises. We provide conditions under which asymmetric equilibria exist and characterize these equilibria. In addition, we compare results for uniform-price auctions to those for discriminatory auctions, and we compare our SFE predictions to equilibrium predictions of models in which bidders are constrained to bid on discrete units of output.     

Multimarket Contact and Intensity of Competition: Evidence from an Airline Merger

This paper examines the relationship between multimarket contact (MMC) and the intensity of competition. We take advantage of a recent merger, which altered the extent of MMC throughout the US airline industry, to understand the nature of MMC’s impact on the airlines’ frequency of service. Evidence that non-price effects of MMC are a part of the longer-term industry equilibrium is not robust. However, we observe that following the merger the market players started taking the degree of MMC into account in making their frequency decisions in line with the ‘mutual forbearance’ hypothesis; however, the effect showed signs of diminishing over time. Our results have implications for merger evaluation in industries where consolidation may lead to a higher extent of multimarket contact.     

Wage Differentials in São Paulo's Labor Force

To explain the variation in the salaries of specialized workers in São Paulo's industries of transformation, we have used a model made up of five variables: the person's occupational preparation, the influence he may exert within the company because of his occupation, his age, his seniority in the company, and his time on the job. The data obtained for the total sample show clearly that the status of the worker within the company (occupational influence) as well as his occupational preparation and age, are powerful partial determinants of salary levels in São Paulo. On the whole, training is the most powerful of these variables because it has a strong direct effect on wages and because it has an indirect effect on wages through its impact on occupational influence level. Variables indicating experience in the company (seniority) and in the present job are almost negligible. The results suggest the presence of a modern industrial structure where one's technical preparation and position in the company are closely related and where these factors weigh far more heavily than experience on the job and in the company. Except for age, the viable variables used here are special cases of major status dimension: wealth (wages); power (occupational influence); informational status (occupatibnal preparation or education). Occupational prestige was also investigated and, in a stepwise regression, was found useless as a determinant of wages. In this research we explore, possibly for the first time, the use of a power variable, occupational influence, as a determinant of a reward variable, hourly wages. Though theoretically promising, power has previously been remarkably resistant to empirical analysis. Although our use of occupational influence has been successful, the introduction of new variables is always risky. We hope that others will conduct studies leading either to refinements in the use of this and similar indicators or to their rejection. Also, recent publications report only a small effect of most known variables on individual income differentials in the United States. Perhaps adding occupational influence might help. It is worth repeating that in the present data-set, this variable alone explains just about as much variance in hourly wages (23 per cent) as a set of 13 repressors does on job income (27 per cent) in data analyzed by Spaeth. The whole set of five variables is, of course, more effective here, with 36 per cent of the variance explained. These differences may be due to many factors. It would seem that education may be more influential in Brazil—or at least in this sample —than in the United States. Clearly, educated personnel are in shorter supply than in the United States, and the relative rewards may be greater. If this is true, the rewards for education should decrease as Brazil's education system improves. In any case, by its clear elimination of job experience and seniority, and its strong support for occupational training, occupational influence level, and age, we hope the present work may add to the growing body of evidence regarding the determinants of wage differentials, especially in Brazil and perhaps in other dynamic third world sectors.
