The relationship between trust and risk is a topic of enduring interest. Although there are substantial differences between the ideas the terms express, many researchers from different disciplines have pointed out that these two concepts become very closely related in personal exchange contexts....

We present results of an experiment on expectation formation in an asset market. Participants to our experiment must provide forecasts of the stock future return to computerized utility-maximizing investors, and are rewarded according to how well their forecasts perform in the market. In the...

A probability of a partner not fulfilling his forward contract obligations (contract failure) increases in a transition economy. This project investigates the process of price and quantity discovery in a laboratory setting when there is (1) an endogenous choice between forward and spot market...

By providing incentives for sellers to act in a trustworthy manner, reputation mechanisms in many online environments can mitigate moral-hazard problems when particular buyers and sellers interact infrequently. However, these mechanisms rely on buyers sharing their private information about...

In experimental studies pairs that repeatedly play the simple coordination game mutual fate control may regularly fail to coordinate when they are given little in-formation, i.e. when subjects are uninformed about the payoff matrix and feed-back is limited to their own payoff. Our experimental...

Game theory provides predictions of behavior in many one-shot games. On the other hand, most experimenters usually play repeated games with subjects, to provide experience. To avoid subjects rationally employing strategies that are appropriate for the repeated game, experimenters typically...

We conduct experiments of a cheap-talk game with incomplete information in which one sender type has an incentive to misrepresent her type. Although that Sender type mostly lies in the experiments, the Receiver tends to believe the Sender's messages. This confirms ``truth bias'' reported in...

It is often suggested that team spirit counteracts free-riding. Testing for team spirit with field data is difficult, however, due to an inherent identification problem. In this paper test for team spirit experimentally. In a team work task we vary subjects' information about relative team...

We study a class of interactive decision making situations in which each agent must choose to participate in one of several lotteries with commonly known prizes. In contrast to the widely studied paradigm of choice between gambles in individual decision making under risk, the probability of...

A computerized double auction market with human traders is employed to examine the relation of price and volume under conditions of asymmetric information. In this market, the informed traders receive higher precision signals than the uninformed traders. The relation of price and volume has been...
