We propose a novel dynamic car relocation policy for a car-sharing network with centralized control and uncertain, unbalanced demand. The policy is derived from a reformulation of the linear programming fluid model approximation of the dynamic problem. We project the full-dimensional fluid...

The subject of the present paper is a simplified model for a symmetric bistable system with memory or delay, the reference model, which in the presence of noise exhibits a phenomenon similar to what is known as stochastic resonance. The reference model is given by a one dimensional parametrized...

I study the welfare optimal allocation of a number of identical and indivisible objects to a set of heterogeneous risk-neutral agents under the hypothesis that money is not available. Agents have independent private values, which represent the maximum time that they are willing to wait in line...

This paper utilizes queuing models to analyze health care processes. We extend previous queuing models to allow for i) heterogeneous resources, ii) resource allocation to various tasks, and iii) teams (complementary resources). We model a process of one clinical unit. We use the model to analyze...

We develop a methodology for studying ''large deviations type'' questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are...

We estimate the effects of wait time for orthopedic surgery on health and labor market outcomes of Norwegian workers. Our identification strategy exploits variation in wait times for surgery generated by the idiosyncratic variation in system congestion at the time of referral. While we find no...

We set up a model with search and matching frictions to understand the effects of employment and wage policies, as well as nepotism in hiring in the public sector, on unemployment and rent seeking. Conditional on inefficiently high public-sector wages, more nepotism in public-sector hiring...

This paper documents the effects of last place aversion in queues and its implications for customer experiences and behaviors, as well as for operating performance. An observational analysis of customers queuing at a grocery store, and four online studies in which participants waited in virtual...
