Positive Demand Spillover of Popular App Adoption: Implications for Platform Owners' Management of Complements

( Lee, Mi Hyun | Han, Sang Pil | Park, Sungho | Oh, Wonseok )



As platform owners interact with end users and complementors, their demand side characteristics and performance affect the overall value creation of ecosystems. This research investigated how the emergence of popular complements on a mobile communication platform impacts the usage of other complementary products by the platform's end users and how platform owners can benefit from such demand spillovers. We identified two different forms of demand spillovers (i.e., backward and forward) and conceptualized how each subsequently affects platform expansion. On the basis of individual user-level app usage data, we empirically demonstrated how the presence of a popular app alters the demand structure of a platform through changes in the usage of other apps operating within it. The findings reveal that popular app adoption by users increases the number of apps used and the duration of app usage, excluding the usage of popular apps, only within the platform offering a popular app. These results support the existence of positive spillovers from popular complement adoption on a platform. Such positive within-platform spillovers are derived from both backward spillovers onto existing apps adopted before popular app adoption and forward spillovers onto new apps to be adopted after the uptake of favored apps. These patterns suggest that positive spillovers of popular app adoption occur through both the increased retrieval of existing apps and reduced uncertainty about newly released apps. Furthermore, forward spillover is considerably stronger than backward spillover, implying that platform owners can reap benefits by coordinating the launch of new complements and the promotion of less-known counterparts to end users with the emergence of a popular app. These results shed light on how platform owners can manage their complements and create value beyond direct contributions from popular complements.

Do Firms Redact Information from Material Contracts to Conceal Bad News?

( Bao, Dichu | Kim, Yongtae | Su, Lixin (Nancy) )



The Securities and Exchange Commission (SEC) allows firms to redact information from material contracts by submitting confidential treatment requests if redacted information is not material and would cause competitive harm upon public disclosure. This study examines whether managers use confidential treatment requests to conceal bad news. We show that confidential treatment requests are positively associated with residual short interest, a proxy for managers' private negative information. This positive association is more pronounced for firms with lower litigation risk, higher executive equity incentives, and lower external monitoring. Confidential treatment requests filed by firms with higher residual short interests are associated with higher stock price crash risk and poorer future performance. Collectively, our results suggest that managers redact information from material contracts to conceal bad news.

Shared Fate and Entrepreneurial Collective Action in the US Wood Pellet Market

( Hiatt, Shon R. | Park, Sangchan )



Although studies underscore the importance of creating a coherent collective identity in order to legitimate a new market category, strategy and entrepreneurship research is divided on whether and to what degree an entrepreneur will engage in collective action to promote the identity. To reconcile the inconsistency, we introduce the concept of entrepreneurial shared fate-the belief of a focal venture that it and its competitors are bound together by a sense of belongingness and equally experience similar consequences-and explore how external threats can influence the degree of shared fate. We conceptually distinguish between communal and individual threats and propose that communal threats will increase, whereas individual threats will decrease, shared fate. We also explore boundary conditions that strengthen and weaken the main effects of perceived communal and individual threats on collective identity promotion. Empirically, we examine venture identity framing in response to forest-conservation activism in the U.S. wood pellet market. Implications for research on new market categories, collective identity, optimal distinctiveness, and forest management are discussed.

Good for your fiscal health? The effect of the affordable care act on healthcare borrowing costs

( Gao, Pengjie | Lee, Chang Joo | Murphy, Dermot )



We study the effect of the US Affordable Care Act (ACA) on healthcare borrowing costs. The ACA provides insurance subsidies to low-income enrollees. States could accept funding to expand Medicaid, although many declined, citing the cost burden. The ACA significantly reduced healthcare yields after a favorable 2012 Supreme Court ruling. Furthermore, hospital investment spending increased, and investment-cash flow sensitivities decreased. The yield effect was double in Medicaid expansion states, and insignificant in rural areas of non-expansion states. Our results highlight how the municipal market can be used to evaluate the heterogeneous effects of public policy and guide a targeted policy approach. (C) 2021 Elsevier B.V. All rights reserved.

Mapping Consumers' Context-Dependent Consumption Preferences: A Multidimensional Unfolding Approach

( Park, Junghyun | Kim, Minki | Chintagunta, Pradeep K. )



How, and to what extent, consumer choices are influenced by the context in which the product is consumed remain important marketing questions. In this article, the authors develop a parsimonious context-dependent multidimensional unfolding model that can accommodate consumers' context-specific behaviors via ideal points in multiattribute space along with brand locations in that space while accounting for unobserved heterogeneity in consumer behavior. The authors provide an empirical illustration using panel data on beer brand choices in different contexts from U.S. beer consumers. They find more heterogeneity in behavior across social versus nonsocial contexts than across in-home and out-of-home consumption. The authors then show how the model can be used to derive a firm's optimal direction of brand repositioning given its competitive landscape in the various consumption contexts. Since consumer preferences can be correlated across contexts, they show that a movement toward the ideal point in one context does not necessarily improve the firm's market competitiveness in other contexts; thereby hurting the brand's overall performance.
