Game theory is usually difficult to test precisely in the field because predictions typically depend sensitively on features that are not controlled or observed. We conduct one such test using field data from the Swedish lowest unique positive integer (LUPI) game. In the LUPI game, players pick...

By using hypothetical choice experiments, this paper presents evidence that individuals' concern for relative consumption depends on their relative consumption. Individuals with consumption levels above society's average consumption level tend to have, in general, lower concern for relative...

Science and technology evolve fast both as a result of their internal dynamics and the increased emphasis on research and innovation in the so-called knowledge economy. Due attention to ethical issues and aspects of emerging science and technology is called for. This paper presents the...

Background:Hot spots policing is one of the most influential police innovations, with a strong body of experimental research showing it to be effective in reducing crime and disorder. However, most studies have been conducted in major cities, and we thus know little about whether it is effective...

A central understanding in experimental economics is that subjects’ decisions in the lab are independent of history. We test whether this assumption of between-experiment independence is indeed justified. We analyze experiments with an allocation decision (like a dictator or ultimatum game)...

The 19th and 20th centuries produced breakthroughs in physics, chemistry, and the biological sciences. Laboratory research played an important role in the rapid advances made in these fields. Laboratory research can also contribute progress in the social sciences and, in particular, to law and...
