Mergers in the Presence of Adverse Selection

The RAND Journal of Economics, EarlyView.
ABSTRACT In the presence of adverse selection, mergers can increase welfare through a reduction in inefficient sorting. I characterize the sorting externality internalized between merging firms in a tractable discrete choice model. Mergers benefit consumers when the firms are small, willingness to pay is moderately increasing in cost, and consumer ...

Beyond Manoeuvre Theory for European Defence

Global Policy, EarlyView.
ABSTRACT This article contributes to the debate about European defence in the light of the Russo‐Ukraine war and growing doubts about US commitment to Europe. It argues that Europeans need to fundamentally relearn the ability to imagine military strategy from a European viewpoint.

Sailing Through Time: Building Pacific Maritime Resilience

Global Policy, EarlyView.
ABSTRACT This article examines the Pacific Blue Shipping Partnership (PBSP), an ambitious initiative aimed at decarbonising maritime transport across Oceania. The study explores the cultural, historical and technological aspects of wind‐propelled shipping in the Pacific.

Enriching historical biologging datasets on seabirds using deep neural networks: A transformer‐based approach to infer energy expenditure proxy from GPS and environmental data

Methods in Ecology and Evolution, EarlyView.
Abstract Recent advances in biologging have led to the widespread use of accelerometers, which generate high‐resolution movement data essential for understanding animal behaviour. Derived from tri‐axial accelerometry, Overall Dynamic Body Acceleration (ODBA) serves as a proxy for energy expenditure that is less invasive and more cost‐effective than ...

A continuous‐time random encounter and staying time (REST) model: Moving beyond temporal aggregation in camera‐trap density estimation

Methods in Ecology and Evolution, EarlyView.
Abstract Estimating wildlife population density is fundamental to ecology and conservation. While camera traps have revolutionized the monitoring of medium‐ to large‐sized mammals, estimating the density of unmarked populations remains a major challenge. Current models rely on a critical and often‐violated synchronized activity assumption.

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.
