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...

This paper examines the impact of geopolitical risks (GPR) on oil price volatility over the past three decades, using specifications that capture both long-term patterns and short-term disruptions during periods of stability and crisis. In particular, we analyze oil price volatility’s response to...

Weak states often coexist alongside non-state traditional political institutions (TPIs) in "dual polities," where citizens maintain simultaneous social contracts with both state and non-state authorities. While it is well known that state-building transforms individuals' relationship with the state...

A medical policy can help personalize treatment recommendations based on patients' characteristics. Classical definitions of such policies are often grounded in a causal framework involving a single clinical outcome. In the common setting where several outcomes must be considered simultaneously,...

We study the role of informational complexity on the higher-order rationality of agents in Bayesian games of incomplete information. In a class of dominance solvable Bayesian chain games, we find evidence that informational environments that rely on more private information, and are therefore more...
