Online search engines rely on external content to respond to user queries, while publishers depend on search engines for traffic. The integration of GenAI summaries into search interfaces, such as Google’s AI Overviews (AIOs), may reduce users’ incentives to visit downstream websites, yet causal...

We compare how 126 Tsimane children (ages 6–13) from the Bolivian Amazon and 150 children from a Los Angeles school (LILA, ages 5–8) solve a networked consensus task, in which six players with only local information must agree on one color within 30 seconds. Despite being several years older, the...

We integrate dispersed information into a heterogeneous-agent New Keynesian model in which households cannot fully distinguish idiosyncratic from aggregate income, creating a two-way feedback between household sentiment about future income and aggregate demand. We develop a portable methodology—...

Remote change detection in LLMs is a difficult problem. Existing methods are either too expensive for deployment at scale, or require initial white-box access to model weights or grey-box access to log probabilities. We aim to achieve both low cost and strict black-box operation, observing only...

Social sanctions sustain social order by reinforcing widely accepted principles. Political polarization may weaken this mechanism by fragmenting these principles, yet causal effects are hard to identify: observational data cannot separate the effect of polarized preferences from exposure to...

Risk-on risk-off shocks have pronounced distributional impacts on capital flows, with managed funds playing an increasingly pivotal role in amplifying these effects. This paper demonstrates that among managed funds, passive funds, with their limited discretion and benchmarking mandates,...

The behavioral and social sciences increasingly study similar problems in isolation. Researchers often use different concepts, measures, and disciplinary languages for structurally related situations, making it difficult to understand when we expect that findings will generalize across disciplinary...

In this talk, I will discuss the concept of a barycenter on a general metric space. This notion provides a definition of the “mean” in spaces where the absence of a linear structure makes this concept ambiguous. This notion is particularly useful in Statistics, (metric) geometry, and data science....

We estimate a model of intra-household allocation of time-intensive parental investments. To address the identification challenge of separating preferences, expectations, and bargaining power, we leverage a unique data combination. First, we derive the quantity and quality of maternal and paternal...
