Communication, cooperation and collusion in team tournaments - An experimental study

We study the effects of communication in an experimental tournament between teams. When teams, rather than individuals, compete for a prize there is a need for intra-team coordination in order to win the inter-team competition. Introducing communication in such situations may have ambiguous effects on effort choices. Communication within teams may promote higher efforts by mitigating the internal free-rider problem. Communication between competing teams may lead to collusion, thereby reducing efforts. In our experiment we control the channels of communication by letting subjects communicate through an electronic chat. We find, indeed, that communication within teams increases efforts and communication between teams reduces efforts. We use team members’ dialogues to explain these effects of communication, and check the robustness of our results

Causes, consequences, and cures of myopic loss aversion - An experimental investigation

Myopic loss aversion (MLA) has been established as one prominent explanation for the equity premium puzzle. In this paper we address two issues related to the effects of MLA on risky investment decisions. First, we assess the relative impact of feedback frequency and investment flexibility (via the investment horizon) on risky investments. Second, given that we observe higher investments with a longer investment horizon, we examine conditions under which investors might endogenously opt for a longer investment horizon in order to avoid the negative effects of MLA on investments. We find in our experimental study that investment flexibility seems to be at least as relevant as feedback frequency for the effects of myopic loss aversion. When subjects are given the choice to opt for a long or short investment horizon, there is no clear preference for either. Yet, if subjects face a default horizon (either long or short), there is rather little switching from the one to the other horizon, showing that a default might work to attenuate the effects of MLA. However, if subjects switch, they are more often willing to switch from the long to the short horizon than vice versa, suggesting a preference for higher investment flexibility

Gender, Competition and the Efficiency of Policy Interventions

Recent research has shown that women shy away from competition more often than men. We evaluate experimentally three alternative policy interventions to promote women in competitions: Quotas, Preferential Treatment, and Repetition of the Competition unless a critical number of female winners is reached. We find that Quotas and Preferential Treatment encourage women to compete significantly more often than in a control treatment, while efficiency in selecting the best candidates as winners is not worse. The level of cooperation in a post-competition teamwork task is even higher with successful policy interventions. Hence, policy measures promoting women can have a double dividend.competition, gender gap, experiment, affirmative action, teamwork, coordination

Gender Differences in Competition Emerge Early in Life

We study gender differences in the willingness to compete in a large-scale experiment with 1,035 children and teenagers, aged three to eighteen years. Using an easy math task for children older than eight years and a running task for the younger ones we find that boys are much more likely to enter a tournament than girls across the whole age spectrum considered here. This gender gap is observed already with three-year olds, indicating that gender differences in competitiveness emerge very early in life. The gap is robust to controlling for gender differences in risk attitudes and overconfidence.competition, gender gap, experiment, children, teenagers

The Excess Burden of Tax Evasion: An Experimental Detection-Concealment Contest

We present an experimental study on the wasted resources associated with tax evasion. This waste arises from taxpayers and tax authorities investing costly effort in the concealment and detection of tax evasion. We show that these socially inefficient efforts - as well as the frequency of tax evasion - depend positively on the prevailing tax rate, but not on the fine which is imposed in the event of detected tax evasion. Tax evasion is less frequent, though, than a model with risk neutral taxpayers predicts. We find evidence that this is due to individual moral constraints rather than to risk aversion.tax evasion, contest, experiment, tax rates, fines

Deception through telling the truth?!: Experimental evidence from individuals and teams

Informational asymmetries abound in economic decision making and often provide an incentive for deception through telling a lie or misrepresenting information. In this paper I use a cheap-talk sender-receiver experiment to show that telling the truth should be classified as deception too if the sender chooses the true message with the expectation that the receiver will not follow the sender's (true) message. The experimental data reveal a large degree of 'sophisticated' deception through telling the truth. The robustness of my broader definition of deception is confirmed in an experimental treatment where teams make decisions

Defizit und Wachstumsrate: Ein kurzer empirischer Beitrag zum Stabilitätspakt

Auf dem Gipfel in Amsterdam im Juni 1997 haben sich die Staats- und Regierungschefs der EU-Staaten auf einen Stabilitäts- und Wachstumspakt für die Mitglieder in der Europäischen Wirtschafts- und Währungsunion geeinigt. Welche Auswirkungen und Probleme ergeben sich aus der gegenwärtigen Ausgestaltung des Stabilitätspaktes für die Teilnehmerstaaten der Währungsunion? Wie ist der empirische Zusammenhang zwischen realer BIP-Wachstumsrate und gesamtstaatlichem Nettodefizit gemäß volkswirtschaftlicher Gesamtrechnung
