Small sample performance of the Stein-Rule in non-orthogonal designs

The effects of multicollinearity upon the risk improvement provided by Stein-like estimators over the maximum likelihood estimator in the normal regression model are investigated via Monte Carlo methods. Risk gains are found to degenerate rapidly given moderate degrees of multicollinearity.     

Breaking the norm: An empirical investigation into the unraveling of good behavior

We present results from an artefactual field experiment conducted in rural Peru that considers whether observing non-reciprocal behavior influences an individual's decision to reciprocate. Specifically, we consider the behavior of second movers in a trust game, assessing whether their decision to reciprocate is influenced by the observed reciprocity of others. In documenting the impact of an external shock to observed reciprocity, this paper shows that small increases in non-reciprocal behavior result in an unraveling of the norm of reciprocity. Survey data is used to explore mechanisms by which this occurred. Results are not consistent with learning effects, suggesting that preferences may be changed by observing others deviating from a norm of reciprocity. These results suggest that investing in encouraging trustworthy behavior can have large benefits in situations where individuals are observing each other's behavior, such as may be the case in a new market institution.     

Ready for the Revolution? Why Publishing Consumer Research Is Changing

Thirty‐five years after completing my Ph.D. at the University of Maryland, publishing academic research on consumer well‐being, or any field for that matter, is on the precipitous of major changes that will make it almost unrecognizable during Gen‐Y's scholarly lifetime. There are many possible causes, from technological advancements in publishing to transdisciplinary ways of fostering research. Regardless, how we think, write, read, and review scholarship is undergoing massive reform. We ignore them at our own peril and must reconsider important aspects of our lives as educators, researchers, and citizens.     

Project management infrastructure: The key to operational performance improvement

Process improvement programs such as Six Sigma, Lean, and Lean Sigma are very important and deserve serious academic research attention. However, definition problems make it difficult to study any specific type of process improvement program. Therefore, this study defines two organizational level program management factors, Strategic Project Selection (SPS) and Project Management Infrastructure (PMI), that are independent of any specific process improvement program. Drawing upon current literature, this study develops and tests theoretical models that relate SPS and PMI to operational performance improvement and to each other. Using empirical data collected from 53 supplier plants of one large high-tech firm, this study finds that at the plant level, SPS mediates the relationship between PMI and operational performance improvement. This insight contributes to both theory development and practice, suggesting that a viable strategy for a process improvement program’s success is to focus on PMI in order to enhance SPS and ultimately improve performance.
