The Effect of Providing Peer Information on Retirement Savings Decisions
Abstract—Using a field experiment in a 401(k) plan, we measure the effect of disseminating information about peer behavior on savings. Low-saving employees received simplified plan enrollment or contribution increase forms. A randomized subset of forms stated the fraction of age-matched coworkers participating in the plan or age-matched participants contributing at least 6% of pay to the plan. We document an oppositional reaction: the presence of peer information decreased the savings of nonparticipants who were ineligible for 401(k) automatic enrollment, and higher observed peer savings rates also decreased savings. Discouragement from upward social comparisons seems to drive this reaction.

When Does Familiarity Promote Versus Undermine Interpersonal Attraction? A Proposed Integrative Model from Erstwhile Adversaries
Abstract—This article began as an adversarial collaboration between two groups of researchers with competing views on a longstanding question: Does familiarity promote or undermine interpersonal attraction? As we explored our respective positions, it became clear that the limitations of our conceptualizations of the familiarity-attraction link, as well as the limitations of prior research, were masking a set of higher order principles capable of integrating these diverse conceptualizations. This realization led us to adopt a broader perspective, which focuses on three distinct relationship stages-awareness, surface contact, and mutuality-and suggests that the influence of familiarity on attraction depends on both the nature and the stage of the relationship between perceivers and targets. This article introduces the framework that emerged from our discussions and suggests directions for research to investigate its validity.

The Influence of Strategic Management on Antitrust Discourse
Abstract—This article examines how antitrust law and policy can benefit from ideas developed in the academic strategy field. Because accurate assessment and prediction of the effects of firm conduct depend in part on understanding individual firm capabilities, knowledge from the strategy field and other business fields complements the contributions from industrial organization economics (IO). These business fields also offer theoretical and empirical challenges to the IO paradigm, which dominates antitrust analysis. The article begins with a comparison between strategy and IO and then illustrates how the strategy field can contribute to antitrust merger analysis. The article then assesses the influence of the strategy field on antitrust law and scholarship based on a citation analysis, which reveals little evidence of influence. It concludes with an examination of the likely impediments to the diffusion of strategy field ideas into antitrust.

The Great Recession, Insurance Mandates, and the Use of In Vitro Fertilization Services in the United States
Abstract—Objective: To investigate the relationship between economic activities, insurance mandates, and the use of in vitro fertilization (IVF) in the United States. Design: We examined the correlation between the coincident index (a proxy for overall economic conditions) and IVF use at the national level from 2000 to 2011. We then analyzed the relationship at the state level through longitudinal regression models. The base model tested the correlation at the state level. Additional models examined whether this relationship was affected, both separately and jointly, by insurance mandates and the Great Recession. Results: The coincident index was positively correlated with IVF use at the national level (correlation coefficient = 0.89). At the state level, an increase of one unit in the coincident index was associated with an increase of 16 IVF cycles per 1 million women, with a significantly greater increase in IVF use in states with insurance mandates than in states without mandates (27 versus 15 IVF cycles per 1 million women). The Great Recession did not alter the relationship between the coincident index and IVF use. Conclusions: Our study demonstrates a positive relationship between the economy and IVF use, with greater magnitude in states with insurance mandates. This relationship was not affected by the Great Recession regardless of mandated insurance coverage.

What Are We Meeting For? The Consequences of Private Meetings with Investors
Abstract—Regulation Fair Disclosure was passed in 2000 in response to the concern that certain investors were gaining selective access to privileged firm information. In spite of the passage of this regulation, some investors continue to meet privately with executives. Using a unique set of proprietary records of all one-on-one meetings between senior management and investors for an NYSE-traded firm, we investigate the impact of private meetings on investor decisions. We find that when investors meet privately with management they make more informed trading decisions. This improvement in trading is concentrated in hedge funds but is not present for investment advisors or pension funds. Overall, our results suggest that private meetings help a select group of investors make more informed trading decisions.

Bottlenecks, Modules, and Dynamic Architectural Capabilities
Abstract—How do firms create and capture value in large technical systems? In this paper, I argue that the points of both value creation and value capture are the system's bottlenecks. Bottlenecks arise first as important technical problems to be solved. Once the problem is solved, the solution in combination with property rights can be used to capture a stream of rents. The tools a firm can use to manage bottlenecks are, first, an understanding of the technical architecture of the system and, second, an understanding of the industry architecture in which the technical system is embedded. Although these tools involve disparate bodies of knowledge, they must be used in tandem to achieve maximum effect. Architectural capabilities provide managers with the ability to see a complex technical system in an abstract way and change the system's structure to manage bottlenecks and modules in conjunction with the firm's organizational boundaries and property rights.

Markets with Price Coherence
Abstract—In markets with price coherence, the purchase of a given good via an intermediary is constrained to occur at the same price as a purchase of that same good directly from the seller (or through another competing intermediary). We examine thirteen markets with price coherence, including their origin and outcomes as well as concerns and policy interventions.

The Benefits of Selective Disclosure: Evidence from Private Firms.
Abstract—I investigate an unexplored benefit of being privately held: Non-SEC-filing private firms' ability to disclose confidential information to selected investors minimizes the scope for information asymmetry between the firms and their investors. This decreases private firms' exposure to misvaluation and leads them to hold lower levels of precautionary cash than similar-sized public firms, as private firms do not need to optimize the timing of their equity issues. Consistent with these predictions, I use a unique panel of non-SEC-filing private U.S. firms to show that the average public firm holds twice as much cash as the average private firm. This cash gap is driven by small- and medium-sized public firms, which are most equity dependent, and is larger in industries with higher exposure to misvaluation shocks.

A Methodology for Operationalizing Enterprise Architecture and Evaluating Enterprise IT Flexibility
Abstract—We propose a network-based methodology for operationalizing enterprise architecture. Our methodology is based upon using a "Design Structure Matrix" (DSM) to capture the coupling between different components in a firm's architecture, including business- and technology-related aspects. We apply our methodology to data gathered in a large pharmaceutical firm. We show that this methodology helps to identify layers in the firm's architecture associated with different technologies (e.g., applications, servers, and databases). We also show that it reveals the main "flow of control" within the architecture, as denoted by the classification of components into Core, Peripheral, Shared, and Control elements. We analyze the cost of change for a subset of software applications within this architecture. We find that the cost of change is associated with the degree to which applications are highly coupled. We show the best measure of coupling that predicts the cost of change is one that captures all the direct and indirect connections between components. We believe our work constitutes an important step in making the concept of enterprise architecture more operational, improving a firm's ability to analyze its architecture, understand its performance implications, and adapt and improve it in the future.

Disrupting the Meat Industry: Tissue Culture Beef
Dr. Mark Post and his team at Maastricht University were perfecting their tissue culture beef product-made entirely from muscle grown in his lab-to give it the same taste, texture, and appearance of a traditional beef hamburger. A previous iteration of this product had been taste-tested live, with good results, and Sergey Brin, a cofounder of Google, had provided Post with much of the funding to make the burgers. The next step was to form an independent company around this technology and take it to market. This innovative product could both radically disrupt the existing beef production and supply chain and provide an animal welfare and environmentally friendly food that had far less of an environmental impact than traditional beef products. Post faced several challenges, though, in making this a commercially viable product. He had to get price down, as it currently cost roughly $330,000 to make a single burger. He also had to find the right partner(s) to help him bring the product to market. But who should he work with: someone from the established beef production and supply system, a retailer, or someone entirely outside the traditional beef system? How could he expect established companies to react to this disruption of the status quo? Messaging around this product was critical: How should Post communicate with the public to convey that this was a natural product-the way muscle tissue grew in his lab was the same way it developed in cattle-and overcome public skepticism of overt scientific involvement in their food?

Ardian-The Sale of Diana
The case focuses on a European private equity firm-Ardian-and the process it uses to sell one of its portfolio companies and the decisions around that sale. Key issues include the choice of an auction or acceptance of a preemptive bid, as well as the role of the portfolio company's management in the process. The case explores the kinds of influence company management can, and should, have in the sale process. The case also explores issues at the PE firm level, including the fact that the firm has recently been spun off out of its large parent financial services firm, and how the GP entity was valued during that spinoff.

Jazztel
In October 2004 Fernández Pujals, founder of Telepizza, an international home delivery pizza business, bought 24.9% of Jazztel (€90 million), a telecom company. At the time, Jazztel was near bankruptcy and needed a capital injection to finish the year. Over the next 10 years, Fernández Pujals led the restructuring of Jazztel's debt, reached an agreement with the former monopoly Telefónica, set up internal call centers, and transformed Jazztel into the fastest growing broadband operator in Spain. The case describes how Fernández Pujals designed and managed the board and led Jazztel toward profitable growth.

HomeAway: Organizing the Vacation Rental Industry
In less than 10 years, cofounders Brian Sharples and Carl Shepherd had transformed HomeAway from just another Internet startup into the world's leading vacation-rental marketplace-a global online platform that links customers seeking vacation-home rentals to the property owners and managers who supply them. The case traces HomeAway's founding and acquisition-led growth, its 2011 IPO, and the core elements of its subscription-based business model. By 2014, incumbent travel giants like TripAdvisor and high-profile startups like Airbnb had begun to enter the vacation-rental sector. To stay ahead, HomeAway initiated a pilot cross-platform collaboration to list some of its properties on Expedia's site. More momentously, Sharples was also weighing a new commission-based revenue model that promised to attract a broader array of property listings but at the risk of undermining HomeAway's existing business.

Progressive, 2007-2013
In 2013, Progressive was the fourth largest player in the auto insurance market, having lost the third position to GEICO in 2008. As the industry shifted from agency to online sales, GEICO's direct selling model positioned it strongly for growth. Progressive's direct sales mix had increased from 36% of total sales in 2006 to 42% in 2012, well ahead of the industry average of around 25%. As a result, both Progressive and GEICO continued to gain ground on industry leaders State Farm and Allstate, which sold less than 5% of their policies direct. In 2013, Progressive hoped to revolutionize the purchasing of auto insurance and to build its competitive position with Snapshot, a new usage-based pricing product. First introduced in 2011, Snapshot had low rates of adoption through 2012, but Progressive was redoubling its efforts in 2013 to educate consumers about the product's benefits, which included potential savings of as much as 30% for some drivers. Progressive was also intent on building share with customers that purchased multiple insurance policies since they tended to be more loyal and profitable. Whether these moves would be sufficient to catch up with GEICO was unclear, but they seemed to be working well against State Farm and Allstate.
