We study the convergence of optimistic gradient descent ascent in unconstrained bilinear games. For zero-sum games, we prove exponential convergence to a saddle-point for any payoff matrix, and provide the exact ratio of convergence as a function of the step size. Then, we introduce OGDA for...

Emotions are said to underlie moral decision-making. We detect intra-judge variation spanning three decades in 1.5 million judicial decisions driven by factors unrelated to case merits. U.S. immigration judges grant an additional 1.4 % points of asylum petitions–and U.S. district judges assign 0.6...

The fair innings principle states that fairness requires allocating life-saving treatments to younger rather than older patients when each would gain the same extension in longevity. It is motivated by the notion that older patients have already benefited from a longer life and so have less claim...

In the Netherlands, Diversity, Equity, and Inclusion (DEI) efforts typically avoid using the term “race”, instead adopting a broader “diversity inclusion” framework that shifts focus from racial inequalities to cultural differences. Our project aimed to introduce, test, and apply a framework to...

Determining how people behave in contexts governed by social norms can clarify both how norms influence human behavior and how norms evolve. We examined cooperative farming harvest division among the Derung, a Tibeto-Burman-speaking horticultural society in southwestern China. In the village of...

We examine the effects of the postulated metric on the measurement of well-being, by comparing, in the (income, lifetime) space, two indexes: the equivalent income index and the equivalent lifetime index. The conditions under which the equivalent lifetime index exists are more restrictive than the...

We investigate the welfare consequences of introducing an online distribution channel in the French car industry, where most sales take place in person through car dealers relying on third-degree price discrimination. We estimate a structural model of demand with unobserved third-degree price...

This paper is concerned with models for matched worker-firm data in the presence of both worker and firm heterogeneity. We show that models with complementarity and sorting can be nonparametrically identified from short panel data while treating both worker and firm heterogeneity as discrete random...
