Lee, Hsiao-Hui; Pinker, Edieal J.; Shumsky, Robert A. - In: Management Science 58 (2012) 8, pp. 1569-1584

This paper studies outsourcing decisions for a two-level service process in which the first level serves as a gatekeeper for a second level of experts. The objective of the system operator (the client) is to minimize the sum of staffing costs, customer waiting costs, and mistreatment costs due...

Working When No One Is Watching: Motivation, Test Scores, and Economic Success

Segal, Carmit - In: Management Science 58 (2012) 8, pp. 1438-1457

This paper provides evidence that scores on simple, low-stakes tests are associated with future economic success because the scores also reflect test takers' personality traits associated with their level of intrinsic motivation. To establish this, I use the coding speed test that was...

Robust Simulation of Global Warming Policies Using the DICE Model

Hu, Zhaolin; Cao, Jing; Hong, L. Jeff - In: Management Science 58 (2012) 12, pp. 2190-2206

Integrated assessment models that combine geophysics and economics features are often used to evaluate and compare global warming policies. Because there are typically profound uncertainties in these models, a simulation approach is often used. This approach requires the distribution of the...

Diversity and Performance

Li, Feng; Nagar, Venky - In: Management Science 59 (2013) 3, pp. 529-544

This study measures the performance of U.S. firms initiating same-sex domestic partnership benefit (SSDPB) policies. The results show that holding these firms upon their SSDPB initiation in a calendar portfolio earns a four-factor annualized excess return (alpha) of approximately 10% over the...

Combining Equity and Utilitarianism in a Mathematical Programming Model

Hooker, J. N.; Williams, H. P. - In: Management Science 58 (2012) 9, pp. 1682-1693

We discuss the problem of combining the conflicting objectives of equity and utilitarianism, for social policy making, in a single mathematical programming model. The definition of equity we use is the Rawlsian one of maximizing the minimum utility over individuals or classes of individuals....

Simple Approaches to Shift, Days-Off and Tour Scheduling Problems

Morris, James G.; Showalter, Michael J. - In: Management Science 29 (1983) 8, pp. 942-950

Shift and days-off scheduling problems have received much attention in the literature of integer programming approaches to workforce scheduling. A typical managerial use would be to schedule full-time employees to minimize the number of labor hours while satisfying variable workforce...

The Solution of Multiperiod Network Models with Bundle Constraints by Aggregation

Aderohunmu, Rotimi S.; Aronson, Jay E. - In: Management Science 39 (1993) 1, pp. 54-71

We present a new network aggregation/disaggregation approach for solving a multiperiod, network model with bundle (Generalized Upper Bounding) side constraints. The model describes production planning and distribution problems. Instead of solving the original multicommodity problem, we transform...
