Machine learning algorithms have become increasingly common and have affect many aspects of our life. However, because the objective of most of the standard, off-the-shelf machine learning algorithms is to maximize the prediction performance, the results produced by these algorithms could be...

There are many contexts where an "everybody else is doing it" attitude is relevant. We evaluate the impact of this attitude in a multi-threshold public goods game. We use a lab experiment to study the role of providing information about contribution behavior to targeted subsets of individuals,...
