The introduction of ChatGPT has fueled a public debate on the use of generative AI (large language models; LLMs), including its use by researchers. In the current work, we test whether delegating parts of the research process to LLMs leads people to distrust and devalue researchers and...

The introduction of ChatGPT has sparked enormous public interest in large language (deep-learning) models, which have been sophisticated enough to perform well on a variety of tasks. One way people are utilizing these models is to construct diets. The prompts often include food restrictions...

We assess the ability of GPT–a large language model–to serve as a financial robo-advisor for the masses, by combining a financial literacy test and an advice-utilization task (the Judge-Advisor System). Davinci and ChatGPT (variants of GPT) score 58% and 67% on the financial literacy test,...

Building on previous research that has established a link between neuroticism and the tendency to avoid uncertainty, and revealed the way foreign securities are perceived by investors, we explore whether variation in the personality trait of neuroticism affects foreign portfolio investment....

The production of meat from farmed animals is problematic both on ethical and environmental grounds. However, we are on the eve of the mass production of cultured (lab) meat. This alternative to conventional meat should be both more environmentally sustainable and cause less harm to animals,...

In this study we investigate whether cross-country variation in investors' mean openness to experience – one of the traits of the Five-Factor Model of personality – has an effect on the level of foreign bias present in international equity portfolios. Building on extant research showing a...

This paper tests whether staying ignorant about the negative consequences of one's own actions affects agents' performance in a real effort experiment. We conducted treatments in which subjects' effort either increased only one's own payoff or also increased the donation to a bad charity....

This paper studies differences in the effect of temperature on cognitive performance by gender in a large controlled lab experiment (N = 543). We study performance in math, verbal and cognitive reflection tasks and find that the effects of temperature vary significantly across men and women. At...
