Bluer in the city: urban male lizards exhibit more intense sexual coloration and lower parasite loads than non‐urban males

open access: yesIntegrative Zoology, EarlyView.
The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

An Aggregative Games Approach to Merger Analysis in Multiproduct‐Firm Oligopoly

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct‐firm price competition with CES and logit demand, allowing for arbitrary firm and product heterogeneity. We provide conditions under which a merger raises consumer surplus, and establish the dynamic optimality of a myopic, consumer‐surplus‐based ...

Stellar archaeology with Gaia: the Galactic white dwarf population

open access: yes, 2015
Gaia will identify several 1e5 white dwarfs, most of which will be in the solar neighborhood at distances of a few hundred parsecs. Ground-based optical follow-up spectroscopy of this sample of stellar remnants is essential to unlock the enormous ...
