Vaccine hesitancy is modelled as an endogenous decision within a behavioural SIR model with endogenous agent activity. It is shown that policy interventions that directly target costs associated with vaccine adoption may counter vaccine hesitancy while those that manipulate the utility of...

The growing adoption of virtual queues in the service and retail industries has been greatly accelerated in recent times. In collaboration with a major ride-sharing platform, we study how the wait time information (WTI) – both its initial magnitude and its subsequent progress over time -...

We consider a single server queueing system where a finite number of customers arrive over time to receive service. Arrivals are driven by appointments, with a scheduled appointment time associated with each customer. However, customers are not necessarily punctual and may arrive either earlier...

It is widely believed that trade agreements are necessary to enable the UK to prosper in world markets. In reality, unilateral free trade is possible and offers many benefits. The UK’s exports of services to the EU owe little to the Single Market as national barriers to trade in services still...

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...
