Do laws shape values? We explore this question by testing a model of law and norms within a legal realm − U.S. obscenity laws − where economic incentives are not the primary drivers of social change. Our randomized experiment had data entry workers transcribe news reports of either progressive or...

In this letter, we summarize our recent work on the welfare impact of recommendation algorithms and propose questions for further study. We model recommendation algorithms as an information structure, which shapes how a third party takes actions that affect the welfare of different individuals in a...

In this paper, we consider the problem of ecological inference when one observes the conditional distributions of Y|W and Z|W from aggregate data and attempts to infer the conditional distribution of Y|Z without observing Y and Z in the same sample. First, we show that this problem can be...

This study explores politically motivated reasoning among U.S. Circuit Court judges over the past 120 years, examining their writing style and use of previous case citations in judicial opinions. Employing natural language processing and supervised machine learn- ing, we scrutinize how judges’...

We propose an asset pricing model featuring time-varying limited participation in both bond and stock markets and household heterogeneity. Households participate in financial markets with a certain probability that depends on their individual income and on asset market conditions. We use indirect...

Based on bike-sharing systems (BSS) data in Toulouse and Lyon, this study examines the impact of COVID-19 on relevant variables to BSS usage. Our findings indicate significant changes in longer travel distances, which would be explained by users who use the BSS at peak hours. Also, there is...

Helmholtz decompositions break down any vector field into a sum of a gradient field and a divergence-free vector field. Such a result is extended to finite irreducible and reversible Markov processes, where vector fields correspond to anti-symmetric functions on the oriented edges of the underlying...
