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.     

Beyond the Flexibility/Security Trade‐Off: Reconciling Confident Consumers with Insecure Workers

The article proposes an analysis of labour markets and related social policy that corrects the supply‐side emphasis that has dominated economic policy since the decline of Keynesian approaches in the late 1970s. It starts from a potential tension between the apparent need of economies for both flexible workers and confident consumers. This can be resolved through three different approaches: separating insecure workers from secure consumers, separating consumption from labour incomes, and integrating flexibility and security within the labour market itself. These approaches are played out across four different contexts: place, time, externalizing problems on to minorities within a given community, internalizing problems within the community. Up to 19 different public policies and corporate practices are identified, occupying different positions on the framework. These go considerably beyond the issues of industrial relations institutions and related social policy that are the normal focus of labour market studies.     

Cost–raising Strategies in a Symmetric, Dynamic Duopoly

This paper provides a characterization of the set of dynamic models in which symmetric duopolists have incentives to raise a common cost. The advantage of the dynamic analysis over existing static models is that it extends the conditions (restrictive in static models) under which symmetric cost raising is profitable. The model is illustrated by standard examples from industrial organization: quantity and price adjustment, and learning–by–doing.     

Commercial and Industrial Demand Response Under Mandatory Time‐of‐Use Electricity Pricing

This paper is the first to evaluate the impact of a large‐scale field deployment of mandatory time‐of‐use (TOU) pricing on the energy use of commercial and industrial firms. The regulation imposes higher prices during hours when electricity is generally more expensive to produce. We exploit a natural experiment that arises from the rules governing the program to present evidence that TOU pricing induced negligible change in overall usage, peak usage and peak load. As such, economic efficiency was not increased. Bill levels and volatility exhibit minor shifts, suggesting that concerns about increased expenditure and customer risk exposure have been overstated.     

Comparing Lead Users to Emergent‐Nature Consumers as Sources of Innovation at Early Stages of New Product Development

The large potential of lead users (LUs) in developing innovative and radically new product concepts is well established in the literature. However, in a widely acknowledged study, Hoffman et al. introduced the new concept of emergent‐nature consumers (ENCs) and showed the superiority of this group of individuals over LUs in developing new product concepts. Consequently, they postulated ENCs to be “the right consumers” to be integrated in new product development processes. In this article, we critically reflect and build on Hoffman et al.'s study and further investigate the promise of the ENC concept as compared to the LU concept. In a pilot study, we replicated the study by Hoffman and colleagues: We conducted a crowdsourcing competition and asked for concepts for new services; those concepts had been generated collectively by the participants and had been assessed by a consumer crowd. In the main study, the participants of a crowdsourcing competition submitted individually generated concepts for products, which were evaluated by industry experts. Across both studies, using different empirical methods in two different contexts, and in contrast to Hoffman et al.'s work, we find support for LUs outperforming ENCs (as well as average users) in generating the commercially most promising concepts. Thus, our insights reinforce the existing user innovation literature and the notion of LUs being the primary source of new product/service concepts.     

Being Innovative While Being Green: An Experimental Inquiry into How Consumers Respond to Eco‐Innovative Product Designs

Eco‐innovations are an effective way for companies to strategically align themselves with customers’ growing environmental concerns. Despite their crucial role, scant research has focused on eco‐innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco‐innovation, its degree of innovativeness, level of eco‐friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco‐innovative product designs across various high‐tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco‐innovative attributes on consumers' perceptions of product eco‐friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco‐friendliness levels of eco‐innovative attributes on consumer adoption intentions in the case of high‐complexity products but not for low‐complexity products, emphasizing the need to adopt different approaches when developing eco‐innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco‐innovative attributes on consumers' perceptions of trade‐offs between environmental benefits and product functionality and on their intentions to adopt eco‐innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research.     

A Further Note on Endogenous Spillovers in a Non-tournament R&;D Duopoly

This note considers the paper of Poyago-Theotoky (1999) on strategic R&D with endogenous spillovers. It proves through an example that, under R&D collusion, optimality sometimes requires either minimal or asymmetric spillovers. It also provides a simple sufficient condition for optimal spillovers between colluding firms to involve maximal spillovers (i.e., complete sharing of information).      

Box‐Office Demand: The Importance of Being #1

We propose a theoretical framework to understand the effect on a movie's eventual theatrical success of leading the box office during the opening weekend. We consider two possible channels: a positive shock to the utility from watching the movie and a greater awareness of the movie's existence. We derive a series of testable predictions, which we test on U.S. box office data. The results suggest that being #1 in sales during the opening weekend has an economically and statistically significant effect on the movie's total demand; and that the primary channel for this effect is through the greater awareness induced by being #1.     

Estimating the Demand for Service Bundles under Three‐Part Tariffs

Consumers may face demand uncertainty when choosing a service plan under three‐part tariffs, and preferences for multiple services may be inter‐dependent. To examine such a demand system, we construct a two‐stage discrete/continuous choice model for service bundles, allowing for interactive utility and preference correlations. Implementing a piecewise maximization approach to consumers’ non‐differentiable utility maximization problem, we estimate the model via simulated method of moments. We empirically illustrate the model using data from a Chinese wireless service provider. Our counterfactual analysis shows that the three‐part tariffs with interchangeable units show no significant loss of revenue, compared to existing tariffs.

Looking for a Needle in a Haystack: How to Search for Bottom‐Up Social Innovations that Solve Complex Humanitarian Problems

The worldwide increase in societal challenges is putting pressure on humanitarian organizations to develop sophisticated approaches to leverage social innovations in the humanitarian sector. Since humanitarian problems are complex problems, with the relevant knowledge being hidden, organizational search theory advocates the application of bottom‐up and theory‐guided search processes to identify the social innovations that solve these. Unfortunately, there has been no theoretical attention to understanding which approaches apply in this context. Further, established theory‐guided bottom‐up search processes, such as the lead user method, are unsuitable to the humanitarian sector, and we lack practice examples of adequate search processes. To start addressing this gap in theory and practice, procedural action research was done with the International Federation of Red Cross and Red Crescent Societies to develop a theory‐guided bottom‐up innovation search process for the real‐life humanitarian problem of recurring floods in Indonesia. It revealed that an innovation search process for this context must differ significantly concerning its objectives and the steps to be taken from the lead user method, which was used as a starting point. Further, a comparison of the technical quality and the social impacts of the identified social innovations with social innovations identified through a non‐theory‐guided bottom‐up search process (i.e., an innovation contest) suggests the superiority of this theory‐guided search process. With this conclusion and the insights derived throughout the development of the search process, this study makes important contributions to theory development in the social and open innovation literatures and delivers important recommendations for social innovation practice in the humanitarian sector.     

Looking Innovative: Exploring the Role of Impression Management in High‐Tech Product Adoption and Use

Although consumer adoption of high‐tech innovations is certainly influenced by the product's functional benefits, can the use of a new product confer social benefits as well? Specifically, can the mere use of an innovative product convey the impression that the user is an innovative person? Impression management (IM) is a well‐established phenomenon in social psychology that refers to the human tendency to monitor, consciously or unconsciously, the efficacy of his or her communication of self to others. This research explores the role that IM motivations, or “looking innovative,” play in consumers' use of new high‐tech products, especially in the workplace—an environment in which innovativeness is clearly valued by employers and, thus, individuals have strong motivations to convey innovativeness as a personal characteristic. Data from both ethnographic and experimental methods demonstrate that (1) the use of new high‐tech products can be a surprisingly effective social signal of one's “tech savvy” and personal innovativeness; (2) this impression even significantly increases positive evaluations of secondary traits such as leadership and professional success; and (3) this effect differs by gender. Intriguingly, stronger benefits accrue for women than for men—a finding that runs counter to the backlash effect typically found in IM research in business settings (i.e., female job evaluations typically suffer after engaging in the same self‐promoting IM strategies that benefit their male counterparts). Further, the data show that, even for professional recruiters, a momentary observation of a job candidate using a new high‐tech product versus a low‐tech equivalent significantly increases the candidate's evaluation and likelihood of being hired.     

Listen to Me,Learn with Me: International Migration and Knowledge Transfer

Existing research on the economic contribution of individual international labour migrants has been couched largely in terms of skills, and has focused on mobility within transnational corporations. This article explores some of the broader links between the literatures on international migration and management, and addresses four main questions: is migrant knowledge selective, is it distinctive, what are the barriers to migrant knowledge transfer and what are the implications for individual migrants and firms. This largely conceptual review is informed by three main premises: the value of adopting a knowledge as opposed to a skills perspective on migration; the importance of examining the cycle of migration rather than static snapshots at particular stages, and the need to consider inter‐firm and extra‐firm migration, as well as intra‐firm mobility.     

FROM EXPERIENCE: Products Talking to People—Conversation Closes the Gap between Products and Consumers

Product design is a complex undertaking, requiring manufacturers to find a balance among business goals, regulatory guidelines, the requirements of the distributor and retailer, and consumer demand. Along the way, it is sometimes easy to forget that, in the end, an actual person will attempt to operate the product.
Manufacturers are skilled at collecting and analyzing data about their customers and at using this information to formulate a "brand message": those things a company wants to communicate to consumers, the expectations that should be set in the consumer's mind, and what feelings and associations consumers should take away from an interaction with the company and its products. But while this information may be useful in understanding demographic and economic aspects of consumers, it often does not help the manufacturer understand how the product and user should interact—how the product and user should "talk" to each other. Something is lost in translation as a product goes from being a conceptual instantiation of a brand to being an actual physical object that a consumer must communicate with and must manipulate. The result is an experience that reflects poorly on the product and the manufacturer.
This article presents a framework for developing the interaction between user and product, using the metaphor of conversation between people. Human beings have developed a set of conversational rules and norms over the last few thousand years, and by leveraging these standards, manufacturers can create product interactions that provide a better experience to the consumer.     

Thinking about U: Theorizing and testing U‐ and inverted U‐shaped relationships in strategy research

Research summary : U‐ and inverted U‐shaped relationships are increasingly explored in strategy research, with 11 percent of all articles published in Strategic Management Journal (SMJ) in 2008–2012 investigating such quadratic relationships. Moreover, a movement towards introducing moderation to quadratic relationships has emerged. By reviewing 110 articles published in SMJ from 1980 to 2012, we identify several critical issues in theorizing and testing of these relationships for which current practice falls short. These include insufficient causal argumentation, incorrect testing, mixing up two different types of moderation, and not realizing that the curve can flip completely. For these and other issues, a guideline is provided which, when followed, may bring clarity to theoretical motivation and rigor to empirical testing. Managerial summary : Too much can be as bad as too little. Many relationships in strategic management follow an inverted U‐shaped pattern, where moderate levels of a strategy lead to optimal performance. To gain deeper insights into the conventional wisdom that too much of a good thing can be harmful to performance, we discuss how such relationships can be better theorized and tested based on a review of articles exploring U‐shaped relationships in Strategic Management Journal during 1980–2012. We identify several critical issues that require close attention and provide a guideline to further develop and validate this important managerial intuition.

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].     

What's in a label?: Consumers,public policy and food labels

All industrialized countries share a minimum set of food-labelling regulations. A major purpose is to protect and inform the consumer and, in recent years, the labelling of nutritional content and of permitted additives has received increased attention. Differences in labelling practices between countries in these areas reflect differing approaches to complex policy issues such as the relative emphasis to be placed on consumer information, as opposed to price or product modification, and the extent of consumer participation in the policy-making process.
