Can enhanced street lighting improve public safety at scale?
Criminology &Public Policy, EarlyView.Abstract Research Summary Street crimes are thought to be influenced by changes in ambient lighting; yet, most studies have focused on small‐scale interventions in limited areas. It remains unclear whether enhanced lighting can improve safety on a larger, jurisdiction‐wide scale.

, 2015 We consider a spectrum sharing scenario, where a secondary network coexists with a primary network of multiple transceivers. The secondary network consists of an energy-constrained decode-and-forward secondary relay which assists the communication ...

Clinical &Experimental Ophthalmology, EarlyView.ABSTRACT Artificial intelligence (AI) has comparable accuracy to ophthalmologists for diabetic retinopathy (DR) screening, yet its cost‐effectiveness is crucial for implementation. Our review of 18 health economic analyses of AI versus manual grading for DR found significant methodological variation, with cost‐utility analysis and Markov modelling ...

Decision Sciences, EarlyView.Abstract We study a supply chain subject to supply disruptions, where the supplier can exert costly effort to mitigate the impact of disruptions and improve reliability. The supplier's current reliability level and the cost of improving reliability can each be high or low and are privately known only to the supplier.

Best Before? Expiring Central Bank Digital Currency and Loss Recovery
Journal of Money, Credit and Banking, EarlyView.Abstract Physical cash enables payments in the absence of electricity or network coverage. Such offline payment functionality promotes the operational resilience and, particularly in developing countries, the accessibility of payments. Central banks are exploring issuing digital cash substitutes with similar offline payment functionality.

Extreme‐weather risk and the cross‐section of stock returns
Journal of Risk and Insurance, EarlyView.Abstract We document an extreme‐weather risk premium in the cross‐section of stock returns. Between 1995 and 2019, stocks of domestic U.S. firms with the most negative sensitivity to aggregate storm losses earned an annual excess‐return spread of more than 6 percentage points relative to those with the most positive sensitivity, a difference not ...
