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 ...

Stochastic Approximation, Momentum, and Nash Play [PDF]
Main objects here are normal-form games, featuring uncertainty and noncooperative players who entertain local visions, form local approximations, and hesitate in making large, swift adjustments.

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 ...

Strong Berge and Pareto Equilibrium Existence for a Noncooperative Game [PDF]
In this paper, we study the main properties of the strong Berge equilibrium which is also a Pareto efficient (SBPE) and the strong Nash equilibrium (SNE).

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

On the existence of Nash equilibrium in electoral competition [PDF]
This paper generalizes previous existence results on unidimensional electoral competition, by extending the traditional two-party electoral game to the case where parties have mixed motivations, in the sense that they are interested in winning the ...

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 ...

A formula for Nash equilibria in monotone singleton congestion games [PDF]
This paper provides a simple formula describing all Nash equilibria in symmetric monotone singleton congestion games. Our approach also yields a new and short proof establishing the existence of a Nash equilibrium in this kind of congestion games without

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 ...
