Large Language Models (LLMs) have the potential to profoundly transform and enrich experimental economic research. We propose a new software framework, "alter_ego", which makes it easy to design experiments between LLMs and to integrate LLMs into oTreebased experiments with human subjects. Our...

Using a revealed preference approach, we conduct an experiment where subjects make choices from linear convex budgets in the domain of risk. We find that many individuals prefer mixtures of lotteries in ways that systematically rule out expected utility behavior. We explore the extent to which...

Previous research consistently identified differences in time preferences between effort and monetary decisions. However, the root cause of this difference- whether it stemmed from the intrinsic nature of the outcomes or the associated pleasurable or unpleasurable experiences-remained undefined....

Many experimental studies report that economics students tend to act more selfishly than students of other disciplines, a finding that received widespread public and professional attention. Two main explanations that the existing literature offers for the differences found in the behavior...

We study how the diffusion of broadband Internet affects social capital using two data sets from the UK. Our empirical strategy exploits the fact that broadband access has long depended on customers position in the voice telecommunication infrastructure that was designed in the 1930s. The actual...

By means of a laboratory experiment, we show that, contrary to standard consumer theory, financially equivalent balance sheet profiles may be perceived as non fungible in a controlled frictionless environment with no probabilistic attributes. A large majority of subjects indeed have a bias in...

We study the role of face-to-face interaction for gender differences in deceptive behavior and perceived honesty. In the first part, we compare women's to men's deceptive behavior using data from an incentivized income reporting experiment in which lies can be detected in the course of an audit....

This paper synthesizes recent research in economics and psychology on the measurement and empirical importance of personality skills and preferences. They predict and cause important life outcomes such as wages, health, and longevity. Skills develop over the life cycle and can be enhanced by...

Do people only reject interference and keep control in order to affect the outcome? We find that 20% of subjects reject unrequired help and insist on their solution to a problem – although doing so is costly and does not change the result. We tease out the motives by varying the information...

We validate experimentally a new survey item to measure the preference for competition. The item, which measures participants' agreement with the statement "Competition brings the best out of me", predicts individuals' willingness to compete in the laboratory after controlling for their ability,...
