We study whether subways alleviate road congestion by examining 45 subway line launches in China and using detailed data on road speed. Our difference-in-differences estimation finds that in the first year after a subway line is launched, rush-hour speed on nearby roads increases by about 4%....

I examine blockchain congestion episodes caused by more than 4,400 triggers for ransomware attacks over a two-year period. When demand for settlement exceeds blockchain capacity, blockchain users engage in fee competition to prioritize their transaction settlement. A typical surge in ransomware...

Using data from over 300,000 visits to an emergency department (ED), we study the accuracy of gatekeeping decisions (admission to the hospital or discharge home) and the effectiveness of a second gatekeeping stage (a clinical decision unit (CDU) in our context) at reducing gatekeeping errors....

Because a hospital is an interconnected, interdependent network of care units, allocating resources — beds, nurses, and improvement initiatives — to one unit to reduce its congestion may have spillover effects on other units. As such, to identify the bottleneck unit and improve access to...

Autonomous vehicle (AV) technologies lower the private cost of driving, leading to induced demand for road use at peak times. Because adoption is likely to skew towards higher-income commuters, we show that the congestion externalities exacerbated by adoption are likely to be experienced...

A common feature in different courts of appeal, including the Supreme Courts of different countries is inordinate delay in administration of justice. Increasing caseload per judge is often treated as the culprit and hiring more judges is a popular corrective device. Particularly, for the Supreme...

We use unique data on work hours of Federal Reserve bank supervisors and a structural model to provide new insights on the impact of bank supervision, the efficiency of the allocation of supervisory resources, and the shape of supervisory preferences. We find that supervision has an economically...

Consider two profit-maximizing service firms in the presence of congestion-sensitive customers. Firms set their prices and compete to capture market share. We compare cases where the firms can invest either independently (competition) or jointly (co-opetition) in congestion-reduction (CR)...

This paper proposes a model of the ridesourcing market in presence of traffic congestion and with the provision of both solo and pooling services. Our analysis of the first-best solution shows that, under a highly congested scenario, the ridesourcing platform may enjoy non-negative profits....

Purpose: With this work, we intend to promote research on the application of Operations Management tools in order to assist with decision-making in health crisis situations. During the first six weeks of the COVID-19 crisis in Spain, we have contacted a large number of hospital and health...
