This investigation deals with the active learning hypothesis in Karasek and Theorell’s (1990) job demands-control model. The active learning hypothesis holds that high levels of learning and selfefficacy will occur among incumbents of high job demands/high job control jobs, whereas low levels of learning and self-efficacy will be found in low demands/low control jobs. This study tested these no...

We study a scheduling problem with deteriorating jobs, i.e., jobs whose processing times are an increasing function of their start times. We consider the case of a single machine and linear job-independent deterioration. The problem is to determine an optimal combination of the due date and schedule so as to minimize the sum of due-date, earliness and tardiness penalties. We give an O(n logn) t...

The Beveridge curve depicts the empirical relationship between job vacancies and unemployment, which in turn reflects the underlying efficiency of the job matching process. Previous analyses of the Beveridge curve suggested deterioration in match efficiency during the 1970s and early 1980s, followed by improved match efficiency beginning in the late 1980s. This paper combines aggregate and regi...
