This paper presents a model for the study of operations at an inbound call center. The call center is modeled as a multi-class processor shared loss system, where the interacting effects of human, telecommunication and information technology resources are explicitly incorporated. Product form solutions for this type of system are provided along with expressions for performance measures like blo...

Economic performance depends crucially on how parties adapt to changing circumstances. We therefore study how the organization of economic activity can facilitate such adaptation. We focus on settings where spot transactions would produce inefficient adaptation, so we ask whether alternative governance structures (allocations of control) facilitate relational contracts that improve on spot adap...

We study an M/G/1 queueing system where the arrival follows Poisson Process. The server provides service in two stages, the first stage service is essential and the second stage of service is optional. If the system is empty then the server goes for a vacation of random duration and after returning from vacation the server decides to take a second vacation which is optional. When the server is ...

We examine solutions in which neither player is worse off from the leadership of one in a policy maker-public game. The loop model of dynamic games is used. Outcome space is dotted with equivalence classes of solutions. The Dynamic Stochastic General Equilibrium (DSGE) results and their New Keynesian variants might represent one category. The economy is the neighborhood of a market-clearing equ...

We discuss and examine empirically a firm-level equivalent of the ancient problem of ‘tying the King’s hands’, namely how to avoid managerial intervention that is undertaken to reap private benefits but is harmful to overall value creation, that is, ‘managerial opportunism’. The link from managerial intervention to firm-level value-creation is moderated by employee motivation. Thus, interventio...

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...
