Covenants not to Compete, Labor Mobility, and Industry Dynamics

April M. Franco and Matthew F. Mitchell
Conventional wisdom among legal scholars is that contractual restrictions on employee mobility affect turnover and led to the overtaking of Massachusetts' Route 128 by Silicon Valley. We study a model of employee mobility in the spirit of Pakes and Nitzan to see when this can be the case. We show that, in fact, with certain frictions taken into account, a model of employee mobility can not only replicate the overtaking by Silicon Valley, but it can also help to explain Route 128s early dominance. Further, the model explains the relative success of firms that start as, or generate, spin-outs.

Herding versus Hotelling: Market Entry with Costly Information

David B. Ridley
Why do businesses such as fast-food restaurants, coffee shops, and hotels cluster? In the classic analysis of Hotelling, firms cluster to attract consumers who have travel costs. We present an alternative model where firms cluster because one firm is free riding on another firm's information about market demand. One consequence of this free riding is that an informed firm might forego a market that it knows to be profitable. Furthermore, an uninformed firm might earn higher profits when research costs are high, because it can credibly commit to ignorance.

Primetime Spin: Media Bias and Belief Confirming Information

Jeremy Burke
This paper develops a model of media bias in which rational agents acquire all their news from the source that is most likely to confirm their prior beliefs. Despite only wishing to make the correct decision, agents act as if they enjoy receiving news that supports their preconceptions. By exclusively gathering information from a source biased towards his prior, there is little chance an agent will be persuaded to change his mind. Moreover, it is shown that even an unbiased agent prefers to receive biased news as it is unlikely to produce conflicting reports. The media caters to the informational demands of consumers and accordingly slants its reporting. It is shown that competition may not decrease bias, but may actually enhance it. Finally, even when it increases bias, competition may improve welfare by expanding the market for news.

In Defense of Boards

Silvia Dominguez-Martinez, Otto H. Swank and Bauke Visser
It is often assumed that bad corporate performance means a bad CEO. The task of a board of directors is then simple: dismiss the executive. If it fails to do so, the board is said to be indolent. We take a kinder approach to observed board behavior and point to the problems even well-intended boards would encounter. They face the twin task of disciplining and screening executives. We analyze the nature of the retention contract a board uses to discipline and screen executives. Consistent with empirical observation, we find that executives may become overly active to show their credentials, and that the link between bad performance and dismissal is weak.

Finitely Loyal Customers, Switchers, and Equilibrium Price Promotion

Bing Jing and Zhong Wen
This present paper aims to provide some new perspectives on how firms' price promotional decisions may depend on different levels of brand loyalty and switcher population. We present a duopoly model with a segment of price-sensitive switchers and a segment of customers who are loyal to one of the two brands but have limited brand loyalty. Our unique equilibrium splits into three types, depending upon configurations of brand strength and switcher population. The type of equilibrium for high brand loyalty corresponds to the one in Narasimhan. The remaining two types for intermediate and low brand loyalty demonstrate strikingly different properties. First, the strong brand has a higher price range and a higher regular price. Second, the strong brand has a higher (lower) average promotional depth than the weak brand when the switcher population is small (large). Third, both brands promote equally frequently when brand loyalty is relatively low.

Pricing Internal Trade to Get a Leg up on External Rivals

Anil Arya and Brian Mittendorf
The pricing of transfers from parent to subsidiary is an oft-explored issue. Linking the cost of internal transfers with external market prices is one common approach, typically justified when the market for the good is perfectly competitive. This paper shows that imperfect competition may also justify market-based transfer prices. Concern that transfer price will deviate from marginal cost and thereby distort subsidiary choices can lead a parent to undertake actions to influence the market price of the upstream good. Such efforts can provide a desirable strategic posture in the upstream market.

Strategic Disclosure of Intermediate Research Results

David Gill
We analyze the incentives to disclose intermediate research results during the course of a patent contest. Despite knowledge spillovers, the leading innovator sometimes discloses to signal commitment to the project, and so potentially inducing a rival's exit. Surprisingly, when development costs are low the leading innovator does not need to disclose to induce the same strategic deterrence effect as that which arises from disclosure. Taking into account wasteful duplication of R&D effort, a patent office can increase welfare by choosing the probability of granting a contested patent and so altering the proportion of rivals that the leading innovator deters.

Strategic R&D Location by Multinational Firms: Spillovers, Technology Sourcing, and Competition

René Belderbos, Elissavet Lykogianni and Reinhilde Veugelers
This paper develops a model of strategic interaction in R&D internationalization decisions between two multinational firms, competing both abroad and in their home markets. It examines different incentives for foreign R&D faced by a technology leader and a technology laggard. The model takes into account the impact of local inter firm R&D spillovers, (noncostless) international intra firm transfer of knowledge, and the notion that internal R&D increases the effectiveness of incoming spillovers. Analytical results suggest that greater efficiency of intra firm transfers and greater R&D spillovers increase the attractiveness of domestic R&D for the technology leader if the technology gap with the laggard is large. The lagging firm, in contrast, increases the share of foreign R&D as foreign technology sourcing becomes more effective. Competition encourages the leading firm to engage in foreign R&D to capture a larger share of profits on the foreign market, whereas the laggard concentrates more R&D at home to defend its home market position.

A Citation-Based Ranking of Strategic Management Journals

Ofer H. Azar and David M. Brock
Rankings of strategy journals are important for authors, readers, and promotion and tenure committees. We present several rankings, based either on the number of articles that cited the journal or the per article impact. Our analyses cover various periods between 1991 and 2006, for most of which the Strategic Management Journal was in first place and Journal of Economics & Management Strategy (JEMS) second, although JEMS ranked first in certain instances. Long Range Planning and Technology Analysis & Strategic Management also achieve a top position. Strategic Organization makes an impressive entry and achieves a top position in 2003–2006.
