Remediating System Neglect In Judgmental Demand Forecasting, Srikant Vinakota

Dissertations and Theses Collection (Open Access)

Prior research has shown that individuals tasked with judgmental forecasting of demand based on time-series data overreact in stable environments and underreact in unstable environments. Kremer et al. (2011) attributed this to the system neglect hypothesis, which claims that forecasters emphasize forecast errors over the system parameters.

The present research investigates interventions that mitigate system neglect and address the causal factors for overreaction and underreaction. Given the desire by organizations to move towards touchless planning and automated decision-making, minimizing human judgment and understanding its drivers is of significant practical importance.

We tested four different interventions on an online subject pool …

Automatic Scoring Of Speeded Interpersonal Assessment Center Exercises Via Machine Learning: Initial Psychometric Evidence And Practical Guidelines, Louis Hickman, Christoph N. Herde, Filip Lievens, Louis Tay

Research Collection Lee Kong Chian School Of Business

Assessment center (AC) exercises such as role-plays have established themselves as valuable approaches for obtaining insights into interpersonal behavior, but they are often considered the “Rolls Royce” of personnel assessment due to their high costs. The observation and rating process comprises a substantial part of these costs. In an exploratory case study, we capitalize on recent advances in natural language processing (NLP) by developing NLP-based machine learning (ML) models to investigate the possibility of automatically scoring AC exercises. First, we compared the convergent-related validity and contamination with word count of ML scores based on models that used different NLP methods …

Employer Branding In The Healthcare Sector: The Role Of Instrumental And Symbolic Image Attributes Among Potential Applicants And Doctors, Jiaxin Luo, Aristides I. Ferreira, Filip Lievens, Beatriz R. Trigo

Research Collection Lee Kong Chian School Of Business

This study draws from the instrumental-symbolic framework to analyze the employer image of public hospitals among final-year students and employed doctors. We examine the relative importance of perceived instrumental and symbolic employer image attributes in public hospitals in China among two groups of individuals (211 final-year students and 200 currently employed doctors). Both instrumental and symbolic attributes are significantly related to hospitals' attractiveness as an employer. Symbolic trait inferences explain incremental variance in employer attraction beyond instrumental attributes. Although both attributes explain similar portions of the variance in the two groups, the attributes that emerge as significantly related to hospitals' …

R&D Project Portfolio Collaboration: How To Structure The Strategic Alliance, Guiyun Feng, Pascale Crama, Wenqi Lian

Research Collection Lee Kong Chian School Of Business

Incumbent companies target innovative firms with promising research and development (R&D) projects to rejuvenate their product portfolio. Such strategic alliances create value by combining the innovator’s research expertise with the partner firm’s superior marketing capability. The partner firm chooses the timing and payment terms of the strategic alliance, accounting for the innovator's budget and marketing capability, and the project portfolio's market interaction and revenue variability. The partner firm may prefer delayed alliances post R&D completion for innovator firms with high marketing capability when the innovator has sufficient budget or when market interaction is weak. Upfront alliances - prior to the …

Going Beyond Western, Educated, Industrialized, Rich, And Democratic (Weird) Samples And Problems In Organizational Research, Marko Pitesa, Michele J. Gelfand

Research Collection Lee Kong Chian School Of Business

The goal of organizational research is to make inferences about a target population based on samples studied. Most target populations referred to in theories of organizational behavior, whether explicitly or implicitly, tend to be the entire populations of workers or managers, or even the entire human population. A typical sample, however, is convenient, being located where most researchers are, and thus also predominantly from Western, Educated, Industrialized, Rich, and Democratic countries (WEIRD; Henrich, Heine, & Norenzayan, 2010).

The Study Of Followers In Leadership Research: A Systematic And Critical Review, Burak Oc, Kraivin Chintakananda, Michael Ramsay Bashshur, David V. Day

Research Collection Lee Kong Chian School Of Business

Despite the significant amount of existing research examining the relationship of follower-related factors with leadership outcomes, there is no systematic, critical review that integrates and helps leadership scholars make sense of this rapidly growing body of research. To address this gap in the literature, we first briefly discuss the leading perspectives explaining the role of followers in leadership. Next, we identify and discuss the most frequently studied theoretical narratives explaining the relationship between follower-related predictors and leadership outcomes. Because theoretical arguments generally make causal claims, we identify and examine how methodological concerns including power analysis, multicollinearity, and endogeneity might prevent …

Biting The Hand That Feeds: A Status-Based Model Of When And Why Receiving Help Motivates Social Undermining, Kenneth Tai, Katrina Jia Lin, Catherice K. Lam, Wu Liu

Research Collection Lee Kong Chian School Of Business

Social exchange theory suggests that after receiving help, people reciprocate by helping the original helpgiver. However, we propose that help recipients may respond negatively and harm the help giver when they perceive helping as a status threat and experience envy. Integrating the helping as status relations framework and the social functional perspective of envy, we examine when and why receiving help may prompt help recipients to undermine help givers. Across four studies, we find progressive support for our results, which show that when individuals receive task-related help from help givers who are perceived to be more, rather than less, competent …

Cheating Constraint Decisions And Discrimination Against Workers With Lower Financial Standing, Grace J. H. Lim, Marko Pitesa, Abhijeet K. Vadera

Research Collection Lee Kong Chian School Of Business

Workers with lower financial standing face many personal challenges due to the relatively lower level of material resources they have at their disposal. We propose that lower financial standing not just impacts workers themselves, but also engenders discrimination from supervisors. Drawing on social cognition principles, we forward a situational inference perspective whereby supervisors make a naïve inference that workers with lower financial standing pose a higher risk of cheating which leads them to subject such workers to more negative treatment and deprive them of opportunities. We focus on two ubiquitous ways in which organizations constrain cheating behavior: worker surveillance and …

Personnel Selection: A Review Of Ways To Maximize Validity, Diversity, And The Applicant Experience, Chad H. Van Iddekinge, Filip Lievens, Paul R. Sackett

Research Collection Lee Kong Chian School Of Business

Personnel Psychology has a long tradition of publishing important research on personnel selection. In this article, we review some of the key questions and findings from studies published in the journal and in the selection literature more broadly. In doing so, we focus on the various decisions organizations face regarding selection procedure development (e.g., use multiple selection procedures, contextualize procedure content), administration (e.g., provide pre-test explanations, reveal target knowledge, skills, abilities, and other characteristics [KSAOs]), and scoring (e.g., weight predictors and criteria, use artificial intelligence). Further, we focus on how these decisions affect the validity of inferences drawn from the …

Work Effort: A Conceptual And Meta-Analytic Review, Chad H. Van Iddekinge, John D. Arnold, Herman Aquinis, Jonas W. B. Lang, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Work effort has been a key concept in management theories and research for more than a century. Maintaining and increasing employee effort also is a persistent concern to managers. The goal of the present conceptual and meta-analytic review was to increase clarity and consensus regarding what effort is and how to measure it. First, we reviewed conceptualizations of effort and provided an integrated definition that views effort as a direct outcome of motivation that captures (a) what employees work on, (b) how hard they work, and (c) how long they persist in that work. Second, we identified four main ways …
