The (relative) cost of the customer’s waiting time has long been used as a key parameter in queueing models, but it can be difficult to estimate. Recently, Singhal, Singhal, and Kumar (2019) introduce a new queue characteristic, the value of the customer’s waiting time, which measures how an...

Markets that involve customers waiting for services or goods in queues whose length they cannot observe are studied. In these markets suppliers truncate queues that become so long that they jeopardize the supplier's future relations with the customer. The length of the queue and the probability...

In the event of a virus outbreak such as COVID-19, testing is key. However, long waiting lines at testing facilities often discourage individuals from getting tested. This paper utilizes queueing-game-theoretic models to study how testing facilities should set scheduling and pricing policies to...

We study the effect of Medicaid expansion on wait time in the emergency department (ED), using a difference-in-differences approach, where the treatment group includes the states that expanded Medicaid at the beginning of 2014 and the control group includes the states that did not expand...

We propose a new class of hedonic models with sticky prices and queues. Time replaces money as the invisible hand in the market. Unlike money, time is non-transferable to the trading partner. We prove the existence and uniqueness of the equilibrium, and we compare our model with the standard...

Motivated in part by online marketplaces such as ridesharing and freelancing platforms, we study two-sided matching markets where agents are heterogeneous in their compatibility with different types of jobs: flexible agents can fulfill any job, whereas each specialized agent can only be matched...

We study the optimal design of a queueing system when agents' arrival and servicing are governed by a general Markov process. The designer of the system chooses entry and exit rules for agents, their service priority---or queueing discipline---as well as their information, while ensuring that...

Shortage of judicial capacity leads to costly delays, stunted economic development, and even failure to deliver justice. This problem is endemic not only in the developing world but also in the congested appeals courts of wealthier nations. Using the Supreme Court of India as an exemplar for...

We consider a general queueing model with a Poisson arrival process whose rate is random, and realized once for the entire process. We show that the distribution of the arrival rate at arrival instants is the size-biased counterpart of the original distribution. In particular, the ASTA (arrivals...
