Decisions under ambiguity depend on both the belief regarding possible scenarios and the attitude towards ambiguity. This paper exclusively focuses on beliefs, measured independent from attitudes. We use laboratory experiments ...

Using a novel theoretical framework and data from a comprehensive field study we conducted over a period of three years, we outline the causal effects of algorithmic discrimination on economic efficiency and social welfare ...

Although the elderly are more vulnerable to COVID-19, the empirical evidence suggests that they do not behave more cautiously in the pandemic than younger individuals. This theoretical model argues that some individuals ...

We show that disclosing machine predictions to affected parties can trigger self-fulfilling prophecies. In an investment game, we experimentally vary investors’ and recipients’ access to a machine prediction about recipients’ ...

We base our analyses on a rich data set that we collected in an incenitivzed field study over a period of three years between 2016 and 2019. Specifically, at the beginning of each semester, we invited first-semester economics ...

A data set comprising 1397 distinct examples. We collected this data in an incentivized field study that we conducted at a large German university over three years (2016-2019) with first-semester economics students. Most ...

In our experiment, participants engage in three subsequent one-shot investment games. Investors initially choose between keeping or investing 10 monetary units (MU) with recipients, who, in the case of investment, decide ...

We collected this data in an incentivized field study that we conducted at a large German university over three years (2016–2019). Most important for the experiment at hand, the field study included an incentivized one-shot ...

By means of three treatments, we identify the causal effect of differences in monetary incentives on the production of social goods allowing for self-selection. The main structure of the experiment is as follows: After ...
