Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

The RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...
