Search Quality and Revenue Cannibalization by Competing Search Engines

Greg Taylor
Consumers are attracted by high-quality search results. Search engines, though, essentially compete against themselves because consumers are induced to substitute away from advertisement links when their organic counterparts are of high quality. I characterize the effect of such revenue cannibalization upon equilibrium quality when search engines compete for clicks. Cannibalization provides an incentive for quality degradation, engendering low-quality equilibria—even when provision is costless. When consumers exhibit loyalty there is a ceiling above which result quality cannot rise, regardless of what the maximum feasible quality happens to be. Seemingly procompetitive developments may exert downward pressure on equilibrium quality.

One-Stop Shopping as a Cause of Slotting Fees: A Rent-Shifting Mechanism

Stéphane Caprice and Vanessa von Schlippenbach
Consumers increasingly prefer to bundle their purchases into a single shopping trip, inducing complementaries between initially independent or substitutable goods. Taking this one-stop shopping behavior into account, we show that slotting fees may emerge as a result of a rent-shifting mechanism in a three-party negotiation framework, where a monopolistic retailer negotiates sequentially with two suppliers about two-part tariff contracts. If the goods are initially independent or sufficiently differentiated, the wholesale price negotiated with the first supplier is upward distorted. This allows the retailer and the first supplier to extract rent from the second supplier. To compensate the retailer for the higher wholesale price, the first supplier pays a slotting fee as long as its bargaining power vis-à-vis the retailer is not too large.

Equilibrium Principal-Agent Contracts: Competition and R&D Incentives

Federico Etro and Michela Cella
We analyze competition between firms engaged in R&D activities and market competition to study the choice of the incentive contracts for managers with hidden productivity. Oligopolistic screening requires extra effort/investment from the most productive managers: under additional assumptions on the hazard rate of the distribution of types we obtain no distortion in the middle rather than at the top. The equilibrium contracts are characterized by effort differentials between (any) two types always increasing with the number of firms, suggesting a positive relation between competition and high-powered incentives. An inverted U curve between competition and absolute investments can emerge for the most productive managers.

Product Innovation Incentives: Monopoly vs. Competition

Yongmin Chen and Marius Schwartz
In contrast to Arrow's result for process innovations, we show that the gain from a product innovation can be larger to a secure monopolist than to a rivalrous firm that would face competition from independent sellers of the old product. A monopolist incurs profit diversion from its old good but may gain more than a rivalrous firm on the new good by coordinating the prices. In a Hotelling framework, we find simple conditions for the monopolist's gain to be larger. We also explain why the ranking of innovation incentives differs under vertical product differentiation.

Do Higher Costs Spur Process Innovations and Managerial Incentives? Evidence from a Natural Experiment

Benoit Dostie and Rajshri Jayaraman
This paper asks whether firms respond to cost shocks by introducing process innovations and increasing the use of managerial incentives. Using a large panel data set of workplaces in Canada, our identification strategy relies on exogenous variation in costs arising from increased border security along the 49th parallel following 9/11. Our longitudinal difference-in-differences estimates indicate that firms responded to the cost shock by introducing new or improved processes, but did not change their use of managerial incentives. These results suggest that the threat of bankruptcy may provide impetus for improving efficiency.

Unshrouding for Competitive Advantage

Carsten Dahremöller
In a market with hidden product details and systematic consumer biases, firms have the possibility to unshroud and thereby to rectify such market obliquities. While the classical view was that firms will have an incentive to unshroud, Gabaix and Laibson (2006) show that there exist constellations in which firms prefer to leave the market shrouded. Building on that model I introduce a more strategic and long-term dimension of unshrouding which turns out to fundamentally alter the underlying incentives to unshroud. In particular, I show that there exists an incentive to unshroud that stems from differences in add-on profitability and that it is dependent on parameter constellations whether a more profitable or a less profitable firm will want to unshroud.

Product Market Competition and Returns to Talent

Jen Baggs, Jean-Etienne de Bettignies, and John Ries
This paper investigates how product market competition influences the wages paid to workers and the distribution of talent across industries. We develop a model where firms facing different competitive conditions bid for workers. The model predicts that wages are increasing in talent, decreasing in competition, and the interaction between talent and competition is positive. In addition, the most talented workers will be concentrated in competitive industries and talent dispersion rises with competition. We use linked employee–employer data to test these predictions.

Multidivisional Strategy and Investment Returns

Gabriel Natividad
This paper studies the influence of multidivisional structure on investment returns using a large database of projects in the U.S. film distribution industry, a setting in which divisionalization exists without horizontal diversification—all divisions of multidivisional distributors release feature films. The findings are consistent with a positive effect of multidivisional strategy on investment returns, even if total investment need not increase. Multidivisional strategies are more consequential for higher profitability when firms share key human talent across their divisions.

Integration and Task Allocation: Evidence from Patient Care

Guy David, Evan Rawley, and Daniel Polsky
Using the universe of patient transitions from inpatient hospital care to skilled nursing facilities and home health care in 2005, we show how integration eliminates task misallocation problems between organizations. We find that vertical integration allows hospitals to shift patient recovery tasks downstream to lower-cost organizations by discharging patients earlier (and in poorer health) and increasing post-hospitalization service intensity. Although integration facilitates a shift in the allocation of tasks and resources, health outcomes either improved or were unaffected by integration on average. The evidence suggests that integration solves coordination problems that arise in market exchange through improvements in the allocation of tasks across care settings.

Oligopolies with (Somewhat) Environmentally Conscious Consumers: Market Equilibrium and Regulatory Intervention

George Deltas, Donna Ramirez Harrington, and Madhu Khanna
We consider a horizontally differentiated duopoly where consumers care about the product's “greenness.” Firms can be asymmetric: they may differ in the product's intrinsic value and may also differ in their chosen level of greenness. We examine the choice of greenness and the implications of various policy interventions. We show that (i) the choices of product greenness are strategic substitutes, (ii) the high-intrinsic quality firm produces the greener product, (iii) the low-quality firm's greenness may increase with the cost of its provision or decrease with consumer willingness to pay for it, (iv) a minimum quality standard (MQS) leads the greener firm to lower its environmental quality and can even reduce average quality, (v) greenness is underprovided even if consumers fully internalize the externality, and (v) an MQS can reduce welfare if the greenness of the high-quality firm exceeds the MQS, even when environmental quality is underprovided. The effects of policy interventions on profits differ qualitatively across polices and firms: A firm that lobbies for one type of intervention may lobby against another similar one, and a firm may lobby for an intervention while its competitor may lobby against it. A subsidy for the development costs of a green product can financially hurt both firms.
