Traditionally, routines have been perceived as a primary source of inertia, which slows down organizational change and hinders organizational adaptation. Advancing prior research on routine dynamics, this study examines how inertia in routines influences the process of organizational adaptation, both in the absence and presence of endogenous change of routines. Contrary to conventional wisdom, our analysis suggests an overlooked mechanism by which routine-level inertia may help, rather than hind

Purpose Consumer expectation not only influences purchase decision but also post-purchase satisfaction and word-of-mouth (WOM). This study aims to develop theories of initial expectation management by suggesting when it is desirable for new products to raise or lower consumer expectations. It systematically examines the interplay of product value and consumer heterogeneity in the dynamic process of new product diffusion under competition. Design/methodology/approach Drawing on traditional diffus

Organizations often respond in different ways to common external shocks. To advance theories on organizational adaptation and performance heterogeneity, it is essential to understand different reasons for different organizational responses. We examine how incumbents in carbon-intensive industries adapt to heightened environmental pressure to reduce carbon emissions. Based on a review of the literature, we propose three dimensions along which diverse organizational responses can be efficiently ma

한국의 모바일 컨텐츠 시장은 모바일 게임의 주도 하에 이제 도입기를 지나 본격적 성장기로 접어들고 있으며, 이동통신사의 3G망 확대와 모바일 기기의 발달로 보다 우호적인 사업 환경이 형성되고 있다. 이에 반해 모바일 게임의 시장 성공 요소에 대한 통합적인 이론적 고찰과 시장 데이터를 토대로 한 실증 연구는 전무해 조속한 관련 연구가 요구되고 있다. 본 연구에서는 국내 이동통신사를 통해 출시된 모바일 게임들에 대한 실증 데이터를 분석함으로써, 통신 서비스 차원이 아닌 모바일 컨텐츠 차원에서 모바일 게임의 시장 성공 요소들과 이러한 요소들의 장르 별 차이 및 출시 후 시간 경과에 따른 변화에 대해 OLS 회귀모형을 통해 분석하였다. 모바일 게임이 성공하기 위해 가장 중요한 것은 디자인 요소였는데, 이는 출시 후 시간이 지남에 따라 보다 중요해졌으며, 특히 시각적 효과가 중요한 RPG/타이쿤/시뮬레이션 장르와 슈팅/액션/아케이드 장르에서 더욱 그 중요성이 컸다. 인기 게임 장르와 사회적

The prevalence of data collected on the same set of samples from multiple sources (i.e., multi-view data) has prompted significant development of data integration methods based on low-rank matrix factorizations. These methods decompose signal matrices from each view into the sum of shared and individual structures, which are further used for dimension reduction, exploratory analyses, and quantifying associations across views. However, existing methods have limitations in modeling partially-share

Abstract In this study, the authors unpack the micro-level processes of knowledge accumulation (experiential learning) and knowledge application (problem solving) to examine how task allocation structures influence organizational learning. The authors draw on untapped potential of the classical garbage can model (GCM), and extend it to analyze how restrictions on project participation influence differentiation and integration of organizational members’ knowledge and consequently organizational e

Abstract In this study, we investigate the role of compulsory education in enhancing financial inclusion across various sociodemographic groups, with a focus on age, gender, and income level. Using data from 160 countries, we employ an instrumental variable model incorporating expected years of schooling and the human rights index to determine the minimum education level necessary for effective financial participation. Our findings reveal that while compulsory education generally promotes financ

One challenge facing omics association studies is the loss of statistical power when adjusting for confounders and multiple testing. The traditional statistical procedure involves fitting a confounder-adjusted regression model for each omics feature, followed by multiple testing correction. Here we show that the traditional procedure is not optimal and present a new approach, 2dFDR, a two-dimensional false discovery rate control procedure, for powerful confounder adjustment in multiple testing.

Imitation by followers has been perceived to erode a leader's competitive advantage and, thus, it is essential for a leader to ensure that imitations are difficult and imperfect. Some industry cases, however, illustrate a puzzling phenomenon whereby leaders help, rather than hinder, followers’ imitation efforts. Drawing on relevant literature and theories, we suggest three rationales behind such strategic behaviour, which we term ‘imitation promotion,’ by a leading firm: (1) to share costs and j
