We introduce and analyse the almost sure convergence of a new stochastic algorithm for the global minimization of Morse functions on compact Riemannian manifolds. This diffusion process is called fraudulent because it requires the knowledge of minimal value of the function to minimize. Its...

We examine pharmaceutical regulations and incentives for innovation from an international perspective, highlighting the public good nature of healthcare innovation and its cross-border diffusion. We summarize the empirical evidence on how push and pull incentives shape R&D investment,...

Does vocational training help correct structural imbalances in the labour market? We propose a new measure of the skills distance between occupations, obtained by fine‑tuning a large language model on a sample of job offers. Using this method, we demonstrate that the “return to employment”...

Oxytocin, a hormone linked to reproduction and health, may mediate life-history trade-offs across the human life course. Yet, how oxytocin naturally varies with age remains poorly understood. Here, working with the Tsimane, forager-horticulturalists of lowland Bolivia, we collected the largest...

Using a novel 15-year data set on surgeon adoption of a complex surgical innovation in the English National Health Service and an identification strategy based on surgeon mobility, this paper disentangles three channels of coworker influence on innovation diffusion: (1) peer network size, (2)...

We provide a non-anthropocentric rationale for implementing a levy on meat consumption due to animal-welfare considerations. It operates as a Pigouvian tax and addresses externalities on farmed animals. Under total utilitarianism, the levy is a subsidy when an animal’s life is worth living, and a...

We analyze the optimal combination of direct and indirect taxes in the presence of tax avoidance. Proportional commodity taxes remain part of the optimal tax structure when avoidance is possible, even when the Atkinson–Stiglitz conditions hold. Taxing consumption, despite avoidance, enhances the...

Vietnam has experienced remarkable economic growth over last three decades, but the country’s development fundamentals remain fragile. This growth has been primarily driven by an expanding labor force and capital deepening, with less emphasis on productivity growth. In this article, we aim to...

Anger and disgust often underlie responses to social transgressions, yet their links to aggressive punishments have been primarily studied in Western populations. Across two studies sampling from Japan, we tested a socio-functional account of these two other-condemning moral emotions, which...
