Conventional wisdom among legal scholars is that contractual restrictions on employee mobility a¤ect turnover and led to the overtaking of Massachusetts’Route 128 by Silicon Valley. We study a model of employee mobility in the spirit of Pakes and Nitzan (1984) to see when this can be the case. We show that, in fact, with certain frictions taken into account, a model of employee mobility can not...

This paper deals with zero-sum stochastic differential games with long-run average payoffs. Our main objective is to give conditions for existence and characterization of bias and overtaking optimal equilibria. To this end, first we characterize the family of optimal average payoff strategies. Then, within this family, we impose suitable conditions to determine the subfamilies of bias and overt...

The problem of motion planning of an autonomous vehicle amidst other vehicles on a straight road is considered. Traffic in a number of countries is unorganized, where the vehicles do not move within predefined speed lanes. In this paper, we formulate a mechanism wherein an autonomous vehicle may travel on the ―wrong‖ side in order to overtake a vehicle. Challenges include assessing a possible o...

background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...

background :although  laparoscopic   cholecystectomy  is   associated  with  less   post-operative  pain compared  to   open  cholecystectomy,  diffuse  shoulder  and  abdominal  pain  is   one    of   the    main postoperative complications in  this technique. the  aim  of this study was  to  compare the  abdominal and shoulder pain after laparoscopic cholecystectomy by  applying intra-abdomin...

Previous work has proved that simple simulation models are sufficient for analyzing the behavior of complex wafer fabs in certain scenarios. In this paper, we give an example where the simple model fails to accurately predict cycle times and WIP levels of the complex model. To determine the reason for this behavior, we analyze the correlation properties of a MIMAC full fab model and the corresp...
