Compositional Data (CoDa) is usually viewed as data on the simplex and is studied via a log-ratio analysis, following the classical work of Aitchison (1986). We propose to bring to the fore an alternative view of CoDa as a stick breaking process, an approach which originates from Bayesian...

We study a situation where physicians differing in their degree of altruism exert a diagnostic effort before deciding whether to test patients to determine the most appropriate treatment. The diagnostic effort generates an imperfect private signal of the patient’s type, while the test is perfect....

This paper analyzes the effect of longevity on parenting choices from a life course perspective. We develop an overlapping generations model to address a core tradeoff that young parents face when investing in their children’s human capital. They can choose a low-time-cost demanding strategy that...

The European Union designates 26% of its landmass as protected areas, limiting economic development for biodiversity. We use the staggered introduction of protected areas between 1985 and 2019 to study the selection of protected land and the causal eect of protection on vegetation cover and...

We first show a simple but striking result in bilevel optimization: unconstrained smooth bilevel programming is as hard as general extended-real-valued lower semicontinuous minimization. We then proceed to a worst-case analysis of box-constrained bilevel polynomial optimization. We show in...

Consider the global optimisation of a function defined on a finite set endowed with an irreducible and reversible Markov generator. By integration, we extend to the set of probability distributions on and we penalize it with a time-dependent generalized entropy functional. Endowing with a Maas’...

Invariant coordinate selection is an unsupervised multivariate data transformation useful in many contexts such as outlier detection or clustering. It is based on the simultaneous diagonalization of two affine equivariant and positive definite scatter matrices. Its classical implementation relies...
