If individual abilities are imperfectly observable, statistical discrimination may affect hiring decisions. In our lab experiment, pairs of subjects solve simple mathematical problems. Subjects then hire others to perform similar tasks. Before choosing whom to hire, they receive information...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...

I explore possible impacts of reciprocal preferences on participation in international environmental agreements. Reciprocal countries condition their willingness to abate on others' abatement. No participation is always stable. A full or majority coalition can be stable, provided that...

At the initial stage of this project, the project group consisted of Asbjørn Aaheim, Magnus Hatlebakk and the authors. The authors are grateful for the discussion with the other project participants at this stage. We also had very useful discussion with the marine researcher Sigurd Tjelmeland...
