Publications in Management Science
Management Science is a scholarly journal that publishes scientific research on the theory and practice of management. The journal includes within its scope all aspects of management related to strategy, entrepreneurship, innovation, technology, and organizations as well as all functional areas of business, such as accounting, finance, information systems, marketing, and operations. The journal includes studies on organizational, managerial, group and individual decision making, from both normative and descriptive perspectives. The articles are primarily based on the foundational disciplines of computer science, economics, mathematics, psychology, sociology, and statistics, but cross-functional, multidisciplinary research that reflects the diversity of the management science professions is also encouraged. The journal interest extends to managerial issues in diverse organizational forms, such as for-profit and nonprofit firms, private and public sector institutions, and formal and informal networks of individuals. We welcome theoretical, experimental (field or lab) and empirical contributions.
Part-Time Bayesians: Incentives and Behavioral Heterogeneity in Belief Updating
Decisions in management and finance rely on information that often includes win-lose feedback (e.g., gains and losses, success and failure). Simple reinforcement then suggests to blindly repeat choices if they led to success in the past and change them otherwise, which might conflict with Bayesian updating of beliefs. We use finite mixture models and hidden Markov models, adapted from machine learning, to uncover behavioral heterogeneity in the reliance on difference behavioral rules across and within individuals in a belief-updating experiment. Most decision makers rely both on Bayesian updating and reinforcement. Paradoxically, an increase in incentives increases the reliance on reinforcement because the win-lose cues become more salient.
