This article sheds light on the relationship between compositional data (CoDa) regression models and multiplicative competitive interaction (MCI) models, which are two approaches for modeling shares. We demonstrate that MCI models are special cases of CoDa models and that a reparameterization links...

The interpretation of regression models with compositional vectors as dependent and/or independent variables has been approached from different perspectives. The first approaches that appeared in the literature are done in coordinate space after some log-ratio transformation of the share vectors....

We document judicial leniency on defendant birthdays across 4.8 million decisions. Our results are consistent with reference-dependent social preferences. First, French sentences are 1% fewer and around 5% shorter. Second, U.S. federal judges also round down sentences except when rounding up makes...

Socioeconomic homophily in friendship networks is the result of several co-occurring processes, which are extremely challenging to disentangle. We propose to study the particular context of a three-week summer camp in France that gathered teenagers from varied socioeconomic backgrounds. We argue...

Theorem 1 in Alger and Weibull (2016, Games and Economic Behavior) consists of two statements. The first establishes that Homo moralis with the right degree of morality is evolutionarily stable. The second statement is a claim about sufficient conditions for other goal functions to be...

Experts and employees in many domains make multiple similar but independent decisions in sequence. Often, the serial position of the case in the sequence influences the decision. Explanations for these serial position effects focus on the role of decision makers’ fatigue, but these effects emerge...

For a linear IV regression, we propose two new inference procedures on parameters of endogenous variables that are robust to any identification pattern, do not rely on a linear first-stage equation, and account for heteroskedasticity of unknown form. Building on Bierens (1982), we first propose an...

Are judges motivated only by policy preferences? Public enforcement of law relies on the use of public agents, such as judges, to follow the law. We use the random assignment of U.S. Federal judges setting geographically-local precedent to document the causal impact of court decisions in a...
