We introduce a new second order stochastic algorithm to estimate the entropically regularized optimal transport cost between two probability measures. The source measure can be arbitrary chosen, either absolutely continuous or discrete, while the target measure is assumed to be discrete. To solve...

I quantify the welfare and environmental gains and losses from a policy establishing an environmental tax/subsidy for new cars in France in 2008. I estimate a structural model of demand and supply that features heterogeneity in consumer preferences to go beyond the average policy effects and...

We study second-degree price discrimination by a two-sided monopoly platform. The incentive constraints of the agents on the value creation side may be in conflict with internalizing externalities on the value capture side, which may render pooling optimal. Even without such conflict between the...

This paper proposes a generalization of Shleifer’s (RAND J Econ 16:319–327, 1985) model of yardstick competition to a dynamic framework. In a differential game setting, we show that the yardstick mechanism effectively replicates the first-best solution if players adopt open-loop behaviour rules and...

Why do humans develop beliefs in supernatural entities that punish uncooperative behaviors? Leading hypotheses maintain that these beliefs are widespread because they facilitate cooperation, allowing their groups to outcompete others in intergroup competition. Focusing on within-group interactions...

Natural resources such as water, for which the availability to users is random, are often shared according to predefined rules. What determines users’ choice of a sharing rule? To answer this question, we designed an experiment in which subjects: (1) vote on sharing rules; (2) choose the technology...

Based on a dataset that we collected from the top research institutions in economics around the globe (including universities, business schools, and other organizations, such as central banks), we document the underrepresentation of women in economics. For the 238 universities and business schools...

The fate of hunting and gathering populations following the rise of agriculture and pastoralism remains a topic of debate in the study of human prehistory. Studies of ancient and modern genomes have found that autochthonous groups were largely replaced by expanding farmer populations with varying...

This paper provides a general method for analysing the sentiments expressed in the language of judicial rulings. We apply natural language processing tools to the text of US appellate court opinions to extrapolate judges’ sentiments (positive/good vs. negative/bad) towards a number of target social...

In this paper, we estimate a structural model of the domestic US airline market to analyse the effect of the recent merger between American Airlines and US Airways. Our results show that, between 2011 and 2016, a substantial fuel price drop, in conjunction with changes in consumer preferences...
