Bodies of Knowledge for Research in Behavioral Operations

Whenever intrepid researchers venture into new terrain, they find that they require knowledge outside of their formal training. This paper reviews bodies of knowledge for operations management (OM) researchers interested in the new area of Behavioral Operations. We highlight theoretical constructs and empirical phenomena from cognitive psychology, social psychology, group dynamics, and system dynamics. We also provide a guide for where to go to learn more about each body of knowledge. Our overall goal is to lower the startup costs for new researchers in Behavioral Operations.     

Correlates and Predictors of Lottery Play in the United Kingdom

Previous studies of lottery play have tended to adopt one particular approach, concentrating on demographic, personality, cognitive, or social aspects of play. Using the recently introduced United Kingdom National Lottery, this study investigated variables associated with all of these approaches within an overall integrative framework. In a community sample (N = 160), Lottery play was positively correlated with friends' Lottery play, Instants Lottery play, frequency of other gambling, and misunderstanding of Lottery probability, and negatively correlated with level of education. In a regression analysis, friends' Lottery play, Instants Lottery play, and education level were significant unique predictors of Lottery play, and a combination of these and other variables accounted for 38% of the variance in playing behavior. The results are discussed predominantly in terms of the nature of lotteries as a social activity.     

How Excessive Stage Time Reduction in NPD Negatively Impacts Market Value

We empirically investigate how time reductions in particular product development stages impact market value. Using longitudinal project data from 107 firms, we compare stage times prior to and following investments in new product development process changes. Our analysis reveals a predominance of focus on time reduction in the late stages of product development. We also find support for the existence of an inverted‐U relationship between market performance and time reductions for some of these stages: beta testing and technical implementation. Therefore, while time reductions can improve time to market, we observe a clear limit to the benefits associated with stage time reductions at particular stages. We also investigate the role of strategic contextual factors such as the extent to which a firm's patented innovations rely upon a variety, as opposed to a limited range, of diverse technology classes. The extent of this technology‐span impacts optimal stage time reductions. We perform an in‐depth post hoc analysis with a small set of firms to uncover how they should invest in stage time reduction given our empirical results. The post hoc analysis highlights that some firms are likely overinvesting in stage time reductions and destroying market value.     

System Dynamics Understanding in Projects: Information Sharing,Psychological Safety,and Performance Effects

Systems thinking has proven useful in project management planning activities and has been suggested as a critical driver of a range of beneficial organizational behaviors. Yet, empirical evidence on the myriad of ways in which systems thinking can impact internal project dynamics and performance remains limited. This study focuses on one aspect of systems thinking in particular: the ability to recognize and understand the dynamics of systems and their features (e.g., feedback and delay). It makes use of a unique, large‐scale interview data set along with objective and structured survey data drawn from multiple sources associated with supply chain system implementation projects. Analysis suggests that an individual's understanding of system dynamics as well as the similarity of such understanding to that typical of their team is, in fact, a strong predictor of both perceptions of psychological safety and information sharing quality in project work. These outcomes appear to mediate the relationship between system dynamics understanding and performance.     

Prioritizing and Monitoring Concurrent Project Work: Effects on Switching Behavior

Project switching occurs when a multi‐project worker shifts his/her attention from one project to another before completing the first project. In this study, we study the effects of two areas of management policy on project switching behavior, project prioritization, and work monitoring. We conduct a controlled experiment to evaluate direct and combined effects of prioritization, scheduled progress checks, and managerial progress checks on project switching behavior in a distributed, multi‐project work environment. We use computerized tasks constituting multiple projects as a means of efficiently simulating a project work setting. Working professionals served as subjects for the experiment, thereby enabling us to control for experience and other individual differences that may vary across workers in real‐world projects. We find that clarifying priorities has little overall effect on the prevalence of switching in our multi‐project setting, while the presence of managerial progress checks has significant and distinct impacts, driving up switch tendencies. Interestingly, various attributes of the timing of these monitoring events also significantly impact the likelihood that workers will switch in response to these event triggers. We discuss the implications of these findings for managerial practice and for future research.     

A measure of disclosure risk for microdata

Summary. Protection against disclosure is important for statistical agencies releasing microdata files from sample surveys. Simple measures of disclosure risk can provide useful evidence to support decisions about release. We propose a new measure of disclosure risk: the probability that a unique match between a microdata record and a population unit is correct. We argue that this measure has at least two advantages. First, we suggest that it may be a more realistic measure of risk than two measures that are currently used with census data. Second, we show that consistent inference (in a specified sense) may be made about this measure from sample data without strong modelling assumptions. This is a surprising finding, in its contrast with the properties of the two 'similar' established measures. As a result, this measure has potentially useful applications to sample surveys. In addition to obtaining a simple consistent predictor of the measure, we propose a simple variance estimator and show that it is consistent. We also consider the extension of inference to allow for certain complex sampling schemes. We present a numerical study based on 1991 census data for about 450 000 enumerated individuals in one area of Great Britain. We show that the theoretical results on the properties of the point predictor of the measure of risk and its variance estimator hold to a good approximation for these data.     

Complementary Drivers of New Product Development Performance: Cross‐Functional Coordination,Information System Capability,and Intelligence Quality

Coordination efforts that access and align relevant cross‐functional expertise are regarded as an essential element of innovation success. In recent years, these efforts have been further augmented through complementary investments in information systems, which provide the technological platforms for information sharing and coordination across functional and organizational boundaries. Somewhat overlooked has been the critical mediating role of the intelligence gained through these efforts and capabilities. This study draws on the theory of complementarity to elaborate on the nature of this mediating concept. Theoretical predictions of the model are tested using instrument variable regression analysis of data collected from a sample of publicly traded US manufacturing firms. The findings suggest that the effects of both internal and external coordination on market intelligence and supply‐chain intelligence are moderated by the firm's information system capability. The effect of both types of intelligence quality on new product development performance was contingent with the effects being enhanced (attenuated) when the market conditions were dynamic (stable). The results are robust to common‐method bias, endogeneity concerns, and alternative estimation methods.

Delinquent Career-Lines: A Conceptual Link Between Theory and Juvenile Offenses*

Theories of delinquent behavior have failed to adequately explain the seeming lack of specialization or development in the delinquent careers of chronic offenders. The extent to which delinquents specialize in their criminal careers is unclear because of inadequacies in two related areas: the offense typologies or classifications used and the failure to consider in the analysis the entire sequence of crimes. It is argued that both of these areas can benefit from utilization of the “career-line” metaphor from occupational literature. The arrest histories of a sample of 767 juveniles were analyzed with a technique—variance centroid scaling—desirable for the classification or scaling of crime. Four dimensions were discovered. An analysis of 62 careers in the sample reveals that three forms of “developmental” careers are prevalent: careers that move (1) from burglary to serious crimes against persons, (2) from status offenses to auto theft, and (3) from all crimes to drug use. The implications of these results are discussed for issues of specialization and diversity in delinquent careers and the respecification of theories and intervention strategies.     

Paradoxical Pathways: An Ethnographic Extension of Kohn's Findings on Class and Childrearing

Stratification is a central issue in family research, yet relatively few studies highlight its impact on family processes. Drawing on in‐depth interviews (N = 137) and observational data (N = 12), we extend Melvin Kohn's research on childrearing values by examining how parental commitments to self‐direction and conformity are enacted in daily life. Consistent with Kohn's findings, middle‐class parents emphasized children's self‐direction, and working‐class and poor parents emphasized children's conformity to external authority. Attempts to realize these values appeared paradoxical, however. Middle‐class parents routinely exercised subtle forms of control while attempting to instill self‐direction in their children. Conversely, working‐class and poor parents tended to grant children considerable autonomy in certain domains of daily life, thereby limiting their emphasis on conformity.
