We study the behavior of experimental subjects who have to make a sequence of risky investment decisions in the presence of network externalities. Subjects follow a simple heuristic – investing after positive experiences and reducing their propensity to invest after a failure. This result...

We test the no-trade theorem in a laboratory financial market where subjects can trade an asset whose value is unknown. Subjects receive clues on the asset value and then set a bid and an ask at which they are willing to buy or to sell from the other participants. In treatments with no gains...

Recently, the theory of informational cascades has been tested in an experiment by Anderson and Holt (1997) who report that their data support the theory amazingly well. In this note we report on an experiment designed to find out whether observed cascades are indeed due to rational Bayesian...

The recent literature on informational cascades has nurtured the impression that cascades can occur only if the action space is coarser than the signal space. In particular, it is sometimes claimed that with continuous action spaces cascades are impossible. In this note we present a simple...

We introduce a generalized theoretical approach to study imitation andsubject it to rigorous experimental testing. In our theoretical analysiswe …nd that the different predictions of previous imitation models aredue to different informational assumptions, not to different behavioralrules. It is...

We analyze the dynamics of neighbourhood watch programs in a local interaction framework. Agents can watch their neighbours' houses and thus deter burglars from breaking in....

While people on all sides of the political spectrum were amazed that Donald Trump won the Republican nomination this paper demonstrates that Trump's victory was not a crazy event but rather the equilibrium outcome of a multi-candidate race where one candidate, the buffoon, is viewed as likely to...
