To advance an evidence-informed policy agenda on this controversial issue, we formed a consortium of national gun violence prevention and mental health experts. The consortium agreed on a guiding principle for future policy recommendations: restricting firearm access on the basis of certain dangerous b...

We analyze an environment in which bidders’ private values change over time due to both private investments and exogenous shocks. We demonstrate that a highlydecentralized mechanism achieves efficiency. The mechanism requires a stage of costly public announcements (i.e., signaling) to induce efficient investment. For this reason, an equilibrium selection issue arises, but can be handled by a mi...

In recent years, with the rapid growth of marine transportation, emergencies in transportation dangerous chemicals have occurred from time to time.

how the connections can be modulated and are flexible in different contexts. We approach these connections of internal representation through models of minimal cognitive systems in a bottom-up approach (Schilling and Cruse, submitted; Schilling and Cruse, 2008). An early neural network model of the own body is grounded in a biological-inspired framework that controls walking in a hexapod robot....

Adolescents engage in a wide range of risky behaviors that their older peers shun, and at an enormous cost. Despite being older, stronger, and healthier than children, adolescents face twice the risk of mortality and morbidity faced by their younger peers. Are adolescents really risk-seekers or does some richer underlying preference drive their love of the uncertain? To answer that question, we...
