The use of expectiles in risk management has recently gathered remarkable momentum due to their excellent axiomatic and probabilistic properties. In particular, the class of elicitable law-invariant coherent risk measures only consists of expectiles. While the theory of expectile estimation at...

Industrialized environments, despite benefits such as higher levels of formal education and lower rates of infections, can also have pernicious impacts upon brain atrophy. Partly for this reason, comparing age-related brain volume trajectories between industrialized and non-industrialized...

Opinion patterns are affected by cognitive biases and noise. While mathematical models have focused extensively on biases, we still know surprisingly little about how different types of noise shape opinion patterns. Here, we use an agent-based opinion dynamics model to investigate the interplay...

We analyze the political impact of a generous solar panel subsidization program. Subsidies far exceeded their social benefit and were partly financed by new taxes on adopters and by electricity surcharges for all consumers. We use local panel data from Belgium and find a decrease in votes for...

Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child‐specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family. At the same time, while foraging, they face...

In a framework where entrants must make sunk investment decisions with uncertain returns and have private demand information, we show that the relationship between innovation and exit value is non‐monotone and features an inverted U‐shaped pattern. Consumer surplus is maximised at the lowest exit...

As algorithms powered by Artificial Intelligence (AI) are increasingly involved in the management of organizations, it becomes imperative to conduct human-centered AI management research and understand people's feelings and behaviors when machines gain power over humans. The two mainstream methods...

An optimality condition for sustainability actions under discounted expected utility is that, ex post, we should almost surely regret having adjusted them too much for risk. In other words, ex post, one would almost surely feel regret for "excess" precautionary saving, excess insurance and hedging...

A substantial body of work in the last 15 years has shown that expectiles constitute an excellent candidate for becoming a standard tool in probabilistic and statistical modeling. Surprisingly, the question of how expectiles may be efficiently calculated has been left largely untouched. We fill...
