This study investigates the spatial and temporal dimensions of im/mobility within the population of western Ukraine. It challenges the typical focus on receiving countries by examining both the capabilities and motivations for staying in Ukraine or considering emigration. Based on data from 1242...

Tipping points define situations where a system experiences sudden and irreversible changes and are generally associated with a random level of the system below which the changes materialize. In this paper, we study a singular stochastic control problem in which the performance criterion depends on...

We study a repeated sender–receiver game where inspections are public but the sender’s action is hidden unless inspected. A detected deception ends the relationship or triggers a finite punishment. We show the public state is low-dimensional and prove existence of a stationary equilibrium with...

This paper studies an infinite-horizon framework in which two large populations of players are randomly matched to play a Prisoner’s Dilemma. Each player lives for two consecutive periods: as a young player from one group, and then as an old player in the other group. Each population has a known...

We prove the existence of a Markov-perfect equilibrium in randomized stopping times for a model of the war of attrition in which the underlying state variable follows a homogenous linear diffusion. We first prove that the space of Markovian randomized stopping times can be topologized as a compact...

Sex-specific division of labour and the associated use of different subsistence techniques by males (e.g., hunting) and females (e.g., gathering) has played an important role in shaping human societies. Skills needed in adulthood are practiced in play during childhood and object play has been...

We embed observational learning (BHW) in a symmetric duopoly with random arrivals and search frictions. With fixed posted prices, a mixed-strategy pricing equilibrium exists and yields price dispersion even with ex-ante identical firms. We provide closed-form cascade bands and show wrong cascades...

"Option value" provides theoretical justification for conserving wildlife species lacking known value, but empirical assessments of actual realizations are rare. We examine quasi-option value in the context of gray wolf eradication, which aimed to protect humans and their property historically, but...
