Surviving the gales of creative destruction: the determinants of product turnover

Innovative industries are often characterized by rapid product turnover. Product longevity may be driven by both a product's position within a market as well as its position within a firm's larger product portfolio. However, we have little understanding of the relative importance of these factors in determining product turnover and how they interact as an industry evolves. Although researchers have invested substantial effort in analyzing firm survival and turnover, there are far fewer studies of the determinants of product survival and turnover. We use hazard rate models and count regression models to describe the behavior of firms and their products with a new and detailed database on the laser printer industry. We show, first, that competition and market structure variables have a large impact on both speeding product exit and delaying product entry. Second, there is some evidence that firms that have maintained a high market share for a number of years keep their products on the market longer than those with lower market share. Finally, firms with high innovative capacity tend to enter markets frequently, but withdraw their products at average rates. Firms with strong brands tend to introduce few products and withdraw their products slowly. With these findings, the paper links product entry and exit decisions to the broader literature on firm strategic and product management. Copyright © 2006 John Wiley & Sons, Ltd.     

Does engagement in corporate social responsibility provide strategic insurance‐like effects?

Research summary : This study examines whether the stock and bond prices of firms engaging in corporate social responsibility (CSR) can benefit from insurance‐like effects during occurrences of negative events. Our results suggest that in the face of negative events, engagement in CSR on a continuous, long‐term basis provides insurance‐like effects on both the stock and bond prices of firms. Nevertheless, the effects are found to quickly disappear following the occurrence of a second, or subsequent, negative event. Although our results clearly indicate that firms need to allocate some of their available resources to long‐term strategic CSR activities, managers must also realize that in a crisis communication, they will probably be able to use their CSR claims on one occasion only. Managerial summary : The purpose of this article is to examine whether firms engaging in corporate social responsibility (CSR) can benefit from insurance‐like effects during occurrences of negative events. We find that on the occurrence of a negative event, long‐term CSR engagement does have insurance‐like effects. We also find that these insurance‐like effects may quickly disappear following the occurrence of a second negative event. Managers of firms with a long history of CSR activities need to realize that in a crisis communication, they can probably use their claims of adherence to CSR only once.

Price-Matching Guarantees and Equilibrium Selection in a Homogenous Product Market: An Experimental Study

Price-matching guarantees have been alleged to sustain collusive prices in a homogenous product market. Theories in this literature also suggest that there exist multiple equilibria (i.e., a set of price equilibria between the competitive and the monopoly price) when all sellers adopt these guarantees in such a market. Theoretical prediction in this case fails to pin down the actual behavior of players a priori. This paper illustrates the essential role of controlled experiment in testing the collusive theory of price-matching guarantees and thereby shedding light on the embedded equilibrium selection problem. In particular, this paper studies two highly stylized market models, obtains testable predictions, and lays out the design of the controlled experiment. Results indicate that these guarantees facilitate collusion among sellers and thus solve the equilibrium selection problem considerably.

The Role of Globalization, Time Acceleration, and Virtual Global Teams in Fostering Successful Global Product Launches

The present article presents a conceptualization of how firms can respond to the issues of globalization and time‐based competition through the use of virtual global teams to foster successful global product launches. It is argued that by combining input, managerial, and transformation‐based competencies effectively, the firm can configure a repertoire of strategic choices (e.g., marketing plans throughout the product development process) based on the national competitive environment, while at the same time being mindful of the need to maintain consistency within the firm's intermediaries operations—both in product development and global product launch. It is further argued that the linkages between globalization and time‐based competition necessitate managerial adjustments in decision frameworks to incorporate accelerated timescapes to maximize effectiveness in global product launch. In an effort to capture the varying impact of time on global decision makers a timescapes perspective is employed, where timescapes are analogous to landscapes because they include the temporal features of socioeconomic events in a variety of socially constructed contexts inclusive of timeframe, tempo, degree of path dependency, synchronization of events, sequence, anticipation, and ubiquity. The recognition of timescapes accentuates the contextual complexity of competition and creates the interface among events, environments, and individuals beyond the traditional numeric concept of clock time, thus requiring modification of a manager's decision‐making perspective. Further, it is argued that due to the rapid pace of globalization, many multinationals in their global product launches require that products, services, technical support, and prices throughout the world need to be coordinated. To effectively accomplish this goal of coordination as an accommodation, firms and their networks can form global virtual teams (i.e., culturally diverse, geographically dispersed, electronically communicating work group of members, who think and act in concert with the diversity of the global environment and intermediary needs–expectations) to enhance global product launch success. Lastly, it is argued that the hypercompetitive global marketplace cannot be managed ex post due to the level of cognitive complexity but must be managed ex ante by developing strategies capable of maintaining flexibility. To accomplish the task of competing in a hypercompetitive landscape, management must understand and incorporate a timescape of events that integrates the various perspectives of those involved in the global product development and launch decision‐making processes. Without a well‐articulated perspective of social time, managers will limit their ability to effectively coordinate global product development and launch across markets, thus hindering the firm's ability to maximize returns.     

Product and environmental social performance: Varying effect on firm performance

Corporate social performance (CSP) consists of actions in different domains that vary in the information they provide stakeholders, and hence, in their effect on firm performance. To demonstrate this, the authors examine the impact of CSP on firm performance in two areas—the product and the environment, referred to as product social performance (PSP) and environmental social performance (ESP), respectively. PSP has a stronger positive impact on firm performance compared to ESP. The findings using disaggregated measures of PSP and ESP indicate negativity bias in that PSP weakness has a stronger negative impact on firm performance compared to PSP strength.

Product variety,sourcing complexity,and the bottleneck of coordination

Research summary: This paper studies the coordination burden for firms that pursue variety as their main product strategy. We propose that product variety magnifies the tension between scale economies in production and scope economies in distribution, giving rise to complex sourcing relationships. Sourcing complexity worsens performance and poses a dilemma for organization design: A hierarchical structure with intermediate coordinating units such as sourcing hubs reduces sourcing complexity for downstream distribution but creates bottlenecks at the hubs, hurting performance for both the hubs and downstream distribution. We empirically examine operations data for about 300 distribution centers within a major soft drink bottling company in 2010–2011. Results support our hypotheses, illuminating the source of complexity in multi‐product firms and the challenge for organization design in managing complexity. Managerial summary: This paper uses data for about 300 distribution centers within a major soft drink bottling company to study how a large product variety creates complex sourcing networks. We find that, in addition to poor performance (e.g., increased stockouts), complex sourcing networks can cause challenges for organization design. In particular, the benefits of converting an existing distribution center into a sourcing hub (i.e., reduction in sourcing complexity for downstream distribution) and the costs of doing so (i.e., reduction in performance for both the hubs and downstream distribution) are both real and significant. The design of an efficient sourcing network despite its complexity involves important managerial decisions. Experiences in building and managing such networks can be the basis of a dynamic capability. © 2016 The Authors. Strategic Management Journal published by John Wiley & Sons Ltd.     

Prices,Profits, and Preference Dependence

We develop a new approach to discrete choice demand for differentiated products, using copulas to separate the marginal distribution of consumer values for product varieties from their dependence relationship, and apply it to the issue of how preference dependence affects market outcomes in symmetric multiproduct industries. We show that greater dependence lowers prices and profits under certain conditions, suggesting that preference dependence is a distinct indicator of product differentiation. We also find new sufficient conditions for the symmetric multiproduct monopoly and the symmetric single‐product oligopoly prices to be above or below the single‐product monopoly price.     

Does product market competition foster corporate social responsibility? Evidence from trade liberalization

This study examines whether product market competition affects corporate social responsibility (CSR). To obtain exogenous variation in product market competition, I exploit a quasi‐natural experiment provided by large import tariff reductions that occurred between 1992 and 2005 in the U.S. manufacturing sector. Using a difference‐in‐differences methodology, I find that domestic companies respond to tariff reductions by increasing their engagement in CSR. This finding supports the view of “CSR as a competitive strategy” that allows companies to differentiate themselves from their foreign rivals. Overall, my results highlight that trade liberalization is an important factor that shapes CSR practices. Copyright © 2014 John Wiley & Sons, Ltd.

The changing face of research anddevelopment in the public sector

This paper examines the changes that have occurred in the management and scale of R & D, in the contextof the'gas industry's experience. As a resultof the discovery o f North Sea gas and new and expanding operations, R & D has become larger, more central, and thus more integrated into and accountable to the organization as a whole. This has resulted in greater centralization and planning administered according to the ‘sponsorship’ principle. These changes have highlighted the problems of R & D choice and the comparison of commercial and non-commercial objectives in a public sector industry. The unique constraints under which nationalized industries operate and their commitment to the ‘public interest’ as well as to commercial goals, are discussed. These bear upon the way in which R & D decisions not amenable to cost/benefit analysis (such as the balance between long and short term work) are made. It is emphasized that these decisions are made by the industry as a whole and that R & D must thus be seen to be complying with industry objectives. The example of British Gas R & D Planning is used to show how ‘sponsorship’ operates and its values for R & D and the restof the industry. Comparison with other public sector industries indicates that there is no one great system for R & D and that its administration is a function of the history, technological characteristics, and present situation of the industry. These imply different procedures appropriate for the innovation process within the Industry. The role of British Gas within a national energy policy is discussed. The separation of the fuel industries affects the assumptions on which R & D plans are made and thus the degree of uncertainty inherent in all R & D planning. This raises interest- ing questions about the degree of flexibility possible in defining each industry's own objectives.     

On the relation between multimarket contact and service quality: Mutual forbearance or network coordination?

Research summary : We reconsider the relationship between multimarket contact and product quality in the airline industry by arguing that multimarket contact has both a negative mutual forbearance effect on quality and a positive network coordination effect on quality. Multimarket contact increases the frequency of contact between firms, and this anticipated future interaction promotes cooperation. In network industries, especially small firms may want to cooperate in order to increase the attractiveness of the composite product. By using size as a moderating variable, we indeed find a consistent positive effect of multimarket contact on product quality for small airlines. We show that this effect can be attributed to network coordination and that this effect generally dominates the negative mutual forbearance effect in a recent period. Managerial summary : Firms with sales in multiple geographical markets likely encounter each other with mutual respect (i.e., live and let live) because aggressive behavior in one market may lead to retaliatory responses in other markets. Such responses weaken competitive pressures on price and quality. Insofar these firms sell complementary products, they may however also coordinate and improve their joint product offering, resulting in better quality for the consumer. This paper shows that this positive effect of cooperation may dominate the negative competition‐reducing effect, depending on the size distribution of firms. The reason is that small or nondominant firms have a stronger incentive to produce compatible products than large or dominant firms with already a strong position in the (global) market.

Waterfall Versus Sprinkler Product Launch Strategy: Influencing the Herd

A seller decides the price and sequence in which a product of unknown value is introduced to consumers. Consumers inspect the product before consumption and observe past prices and sales. Consumption at a high price is informative for later consumers as it indicates that the product is likely to be of high value. I show that on an average prices decrease over time. However, expected revenue on an average rises over time. For a high enough discount factor, I find that for extreme beliefs the firm introduces the product to all consumers but for intermediate values the product is introduced only to one consumer.     

Information Generation in Vertically Differentiated Markets*

In a model of vertical competition two firms draw costly public signals that are informative about the quality of their products and then competitively set prices. When each firm generates information independently from the other, there will be overinvestment (underinvestment) in information generation if the market share of the quality follower in the subsequent market equilibrium is high (low). Moreover, information generation by one firm has a positive externality on the other firm. Hence, coordination (e.g., via industry associations) increases information generation. When product qualities are endogenous, information generation may prevent quality degradation and thus have an additional social benefit.     

Learning and product entry: How diversification patterns differ over firm age and knowledge domains in U.S. generic drug industry

This study uses learning theory to show how knowledge domains affect product extension decisions and how these product decisions change as firms age. Faced with the choice of new product‐markets, a firm might decide to introduce a similar product, by leveraging existing firm knowledge, or to experiment with a less familiar product, which requires new knowledge. Using data on new drug introductions in the US generic pharmaceutical industry, the analyses showed clear support for heterogeneous product‐market entry patterns across knowledge domains as the firm ages. Across time, the form of learning shifts from exploration to exploitation. Copyright © 2013 John Wiley & Sons, Ltd.     

Predicting Spatial Patterns of House Prices Using LPR and Bayesian Smoothing

This article is motivated by the limited ability of standard hedonic price equations to deal with spatial variation in house prices. Spatial patterns of house prices can be viewed as the sum of many causal factors: Access to the central business district is associated with a house price gradient; access to decentralized employment subcenters causes more localized changes in house prices; in addition, neighborhood amenities (and disamenities) can cause house prices to change rapidly over relatively short distances. Spatial prediction (e.g., for an automated valuation system) requires models that can deal with all of these sources of spatial variation. We propose to accommodate these factors using a standard hedonic framework but incoporating a semiparametric model with structure in the residuals modeled with a partially Bayesian approach. The Bayesian framework enables us to provide complete inference in the form of a posterior distribution for each model parameter. Our model allows prediction at sampled or unsampled locations as well as prediction interval estimates. The nonparametric part of our model allows sufficient flexibility to find substantial spatial variation in house values. The parameters of the kriging model provide further insights into spatial patterns. Out–of–sample mean squared error and related statistics validate the proposed methods and justify their use for spatial prediction of house values.

Detecting the relationship between competitive intensity and firm product line length: Evidence from the worldwide mobile phone industry

The way firms lengthen or shorten their product line with respect to rivals is regarded as one of the possible strategies firms can pursue to respond to competition. This article builds and tests hypotheses to study the effect of different levels of competitive intensity on product line length. The empirical analysis of data on 3,527 handset models introduced by 66 mobile phone vendors from 1994 to 2010 shows a consistent inverse U‐shaped relationship between competitive intensity and the firm's product line length. In this way, we pinpoint an interesting link between the product line extension literature and the competitive dynamics and competitive intensity perspectives. Copyright © 2013 John Wiley & Sons, Ltd
