Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

We provide existence results for equilibria of games where players employ abstract (non binary) choice rules. Such results are shown to encompass as a relevant instance that of games where players have (non-transitive) SSB (Skew-Symmetric Bilinear ...

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 ...

NIRA-3: An improved MATLAB package for finding Nash equilibria in infinite games [PDF]
A powerful method for computing Nash equilibria in constrained, multi-player games is created when the relaxation algorithm and the Nikaido-Isoda function are used together in a suite of MATLAB routines.

Seeing like a citizen: Experimental evidence on how empowerment affects engagement with the state
American Journal of Political Science, EarlyView.Abstract Building a strong and effective state requires revenue. Yet, in many low‐income countries, citizens do not make formal payments to the state or forego engaging with the state altogether due to vulnerability to opportunistic demands by state agents. We study two randomized interventions in Kinshasa, Democratic Republic of the Congo, designed to

Homotopy Methods to Compute Equilibria in Game Theory [PDF]
This paper presents a complete survey of the use of homotopy methods in game theory.Homotopies allow for a robust computation of game-theoretic equilibria and their refinements.

American Journal of Political Science, EarlyView.Abstract This paper investigates how politicians use the assignment of officials to geographical posts—a personnel system found in many countries—as a system of incentives to control, and possibly corrupt, bureaucratic behavior. The argument is developed with a matching model and tested with a nationwide survey of Indian officials who administer land ...

On the Existence of Pure Strategy Nash Equilibria in Integer-Splittable Weighted Congestion Games
, 2011 We study the existence of pure strategy Nash equilibria (PSNE) in integer–splittable weighted congestion games (ISWCGs), where agents can strategically assign different amounts of demand to different resources, but must distribute this demand in fixed ...

Annals of Public and Cooperative Economics, EarlyView.Abstract This paper develops a two‐period model to investigate how fiscal and bureaucratic asymmetries shape yardstick competition (YC), inter‐municipal cooperation (IMC), and rent‐seeking in local public service provision. Unlike previous approaches, we allow incumbents to invest in bureaucratic efficiency, influencing both service quality and ...

Lodge moraines: a common yet underreported end‐moraine type—a review
Boreas, EarlyView.Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former
