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.

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 ...

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.

Residual diagnostics for assessing closed population capture–recapture models
Methods in Ecology and Evolution, EarlyView.Abstract Capture–recapture models provide a statistical framework for estimating demographic parameters from incomplete observation data, where not all individuals in a population are detected during sampling. Assessing the fit of such models is crucial for reliable inference.

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.

Animal Conservation, EarlyView.In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...
