Cooperation and Wealth
No full textWe calculate the equilibrium fraction of cooperators in a population in which payoffs accrue from playing a single-shot prisoner’s dilemma game. Individuals who are hardwired as cooperators or defectors are randomly matched into pairs, and cooperators are able to perfectly find out the type of a partner to a game by incurring a recognition cost. We show that the equilibrium fraction of cooperators relates negatively to the population’s level of wealth.Equilibrium fraction of cooperators, Population's level of wealth, Single-shot prisoner's dilemma game

Inequality and Migration: A Behavioral Link
No full textWe provide an analytical-behavioral explanation for the observed positive relationship between income inequality, as measured by the Gini coefficient, and the incentive to migrate. We show that a higher total relative deprivation of a population leads to a stronger incentive to engage in migration for a given level of a population’s income; that total relative deprivation is positively related to the Gini coefficient; and that, consequently, the Gini coefficient and migration are positively correlated, holding the population’s income constant.Income inequality, Relative deprivation, The Gini coefficient, The incentive to migrate

On Weil-Stark elements, II: Refined Stark conjectures
No full textThe theory of Weil-Stark elements is used to develop an axiomatic approach to the formulation of refined versions of Stark’s Conjecture. This gives concrete new results concerning leading terms of Artin L-series and arithmetic properties of Stark elements. © 2024 American Mathematical Society.The first and third authors gratefully acknowledge the generous support of Yonsei University, where parts of this research were completed.
