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...

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 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...

We present an experimental study of investors’ willingness to pay for socially responsible assets. In our initial public offering experiment, various assets share identical financial risk-return profiles but differ in the intensity and timing of societal benefits, represented by charitable...

Genetically modified (GM) crops have been adopted by some of the world’s leading agricultural nations, but the full extent of their environmental impacts remains largely unknown. While concerns about the direct environmental effects of GM crops have declined, GM crops have led to indirect changes...
