Abstract: | This paper reports the results of an experiment on incentive contracts for teams. The agents, whose efforts are complementary, are rewarded according to a sharing rule chosen by the principal. Depending on the sharing rule, the agents confront endogenous prisoner's dilemma or stag-hunt environments. Our main findings are as follows. First, we demonstrate that ongoing interaction among team members positively affects the principal's payoff . Greater team cooperation is successfully induced with less generous sharing rules in infinitely-repeated environments. Second, we provide evidence of the positive effects of communication on team cooperation in the absence of ongoing team interaction. Fostering communication among team members does not significantly affect the principal's payoff , suggesting that agents' communication is an imperfect substitute for ongoing team interaction. Third, we show that offering low sharing rules can back re. The agents are willing to engage in costly punishment (shirking) as retaliation for low offers from the principal. Our findings suggest that offering low sharing rules is perceived by the agents as unkind behavior and hence, triggers negative reciprocity. |

Abstract: | In this paper, we analyze and link self-reported risk perception data obtained from surveys and experimentally elicited risk parameters and use them to explain online shopping behavior. We find that self-reported risk data turn out to be not correlated with the actual risk parameters. Although risk perceptions do not play a significant role in explaining binary online shopping behavior, risk parameters of the subjects elicited via a new hybrid experimental methodology play a very important role. The data also reveals that actually risk-averse subjects tend to report themselves to be just as risk-loving as the ones who exhibit risk-loving behavior. |

Abstract: | In tort litigation, delayed settlement or impasse imposes high costs on the parties and society. Litigation institutions might influence social welfare by affecting the likelihood of out-of-court settlement and the potential injurers’ investment in product safety. An appropriate design of litigation institutions and tort reform requires good knowledge of the factors that affect litigants’ behavior. The combination of theoretical and experimental law and economics, which represents the cornerstone of the application of the scientific method, might enhance our understanding of the effects of litigation institutions and tort reform on settlement and deterrence. We evaluate the interaction between theoretical and experimental law and economics in the study of tort litigation institutions. Special attention is devoted to liability, litigation and tort reform institutions, and behavioral factors that might affect impasse. Our analysis suggests a productive interaction between theoretical and experimental law and economics. In particular, findings from experimental economics work on litigation institutions indicate the presence and robustness of cognitive biases, and provide evidence of the effects of litigants’ biased beliefs on the likelihood of impasse. These findings have motivated the construction of new economic models of litigation involving more empirically-relevant assumptions about litigants’ beliefs. As a result of the application of the scientific method, the contributions of law and economics to the design of legal institutions might be strengthened. |

Abstract: | The present work analyzes the individual behavior in an experimental asset market in which the only task of each player is to predict the future price of an asset. To form their expectations, players see the past realization of the asset price in the market and the current information about the mean dividend and the interest rate. We investigate the mechanism of expectation formation in two different contexts: one with a constant fundamental value, and one in which the fundamental price increases over repetitions. Results show that there is heterogeneity both within and between Treatments. Considering an increasing fundamental value has no impact on the individual expectations but it increases the volatility of the market price. We investigate in depth the reasons behind the observed heterogeneity between groups in the same treatment and results show that the heterogeneity of players' expectations is the main cause of the heterogeneity in the realized price. Looking at the coordination, we find out that homogeneous expectations is not a sufficient condition to have high degree of coordination. We analyze the individual forecasting errors as a determinant of the coordination within group and results show that a positive and significant correlation between individual errors strongly influence the level of coordination. |

Abstract: | Cognitive biases have been intensely studied in security markets so far (Simon 1987). Flyvberg (2005) also found, that project management decisions in the construction of infrastructure suffer from cognitive biases. In the field of real estate development investment decisions no empirical analysis of these social-psychological effects like miscalibration (e.g. Zacharakis/Sheperd, 2001), over optimism (e.g. Heating, 2002) or escalating commitment (Staw/Ross 1987) are known so far. A lot of actual large scale projects like the new Berlin Brandenburg Airport or the new Hamburg Opera House Elbphilharmonie, which is one of the 10 most expensive single building project developments of the last years gives a lot of impressionistically evidence, that the cognition bias of project investment decision makers is one of the most important reasons for running out of time and costs. Therefore we develop a model of cognition biases in real estate development decision situations containing the most relevant biases and the key types of decision makers and situations. Real estate development decisions differ from security investments, because there are several parties who work together in one relatively long lasting project, while they can physically see the project and it's success grow. In a large-scale empirical survey among all types of real estate project decision makers (e.g. sector, hierarchy, personal experience) we analyze and compare the individual degrees of cognition biases with methods coming from the empirical social research. We measure cognition biases and their specific reasons. The results of several univariate and multivariate analyses show heavily cognition biases in real estate investment decisions, which vary intensely between different types of decision makers. Especially in real estate development decisions the degree of bias depends on the individual objective and subjective knowledge and the incentives of the decision maker. We also found evidence, that the degree of the bias in decision situations, which results in inefficiency, is not given, but can reduced by far. So we are able to derive some methodological implications for theory and practice in the field of efficient institutionalizing the project. |

Abstract: | Reputation is a commonly cited check on opportunism in economic and social interactions. But it is often unclear what would motivate an agent to report another’s behavior when the pool of potential partners is large and it is easy enough for an aggrieved player to move on. We argue that behavioral or social preference motivations may solve this conundrum. In a laboratory experiment in which subjects lack any private material incentive to report partners’ actions, we find that most cooperators incur a cost to report a defecting partner when this has the potential to deprive the latter of future gains and to help his next partner. |

Abstract: | We conduct a field experiment on 427 Israeli soldiers who each rolled a six-sided die in private and reported the outcome. For every point reported, the soldier received an additional half-hour early release from the army base on Thursday afternoon. We find that the higher a soldier’s military entrance score, the more honest he is on average. We replicate this finding on a sample of 156 civilians paid in cash for their die reports. Furthermore, the civilian experiments reveal that two measures of cognitive ability predict honesty, whereas self-report honesty questions and a consistency check among them are of no value. We provide a rationale for the relationship between cognitive ability and honesty and discuss the generalizability of this result. |

Abstract: | This paper experimentally studies the disposition effects of teams and individuals. The disposition effect describes the phenomenon that investors are reluctant to realize losses, whereas winners are sold too early. Our experiments compare the investments of two-person teams to a setting where investors trade alone. We find that subjects investing jointly exhibit more pronounced disposition effects than individuals. A closer look reveals that investor teams hardly realize losses and predominately sell winners. The data suggest that decision-dependent emotions may explain the differences. That is, teams reporting high levels of regret exhibit significantly higher disposition effects than individuals. |

Abstract: | Should we discount our own future or should we apply an equal concern to all parts of our life? Many moral philosophers regard no discounting as a virtue. We present arguments on both sides of this debate. A critical comparison of the two conflicting viewpoints on the issue of discounting yields two conclusions. First, no discounting may have undesirable implications in certain economic settings and is often inconsistent with observed individual behavior. Although important in its own right, such an argument falls short of providing a moral basis for discounting. Second, from a normative perspective, there is a strong ethical foundation for no discounting in models of intertemporal choice. |

Abstract: | This paper presents a new theory, called Preference Cloud Theory, of decision-making under uncertainty. This new theory provides an explanation for empirically-observed Preference reversals. Central to the theory is the incorporation of preference imprecision which arises because of individuals’ vague understanding of numerical probabilities. We combine this concept with the use of the Alpha model (which builds on Hurwicz’s criterion) and construct a simple model which helps us to understand various anomalies discovered in the experimental economics literature that standard models cannot explain. |

Abstract: | Purpose –  To examine whether investors in commercial real estate exhibit some important behavioural biases, namely: anchoring, herding, framing/nudging, loss aversion and over-confidence. If so, are there steps that investors and their agents ( fund managers and advisors) could take (a) to temper the effects of their own biases and (b) to exploit the presence of such biases in other market participants? Design/methodology/approach –  Analysis of historic data sources at asset and market levels and over different time periods, with focus on identifying the specific biases listed above, singly and in combination Findings –  Understanding of behavioural bias merits greater attention. Research limitations/implications –  Reliance on inferences from historic data Practical implications –  May help develop clearer understanding of market drivers and improved decision-making for market participants. Originality/value –  New research within the real estate industry that could help investors understand the highly cyclical nature of commercial real estate investment markets Keywords: behavioural biases –  anchoring –  herding –  framing - loss aversion –  over-confidence Article Classification: Viewpoint |

Abstract: | The Dunning–Kruger effect states that the low skilled are overconfident while the high skilled are more accurate in assessing their skill. In apparent support of this effect, many studies have shown that low performers overestimate their performance while high performers are more accurate. This empirical pattern, however, might be a statistical artifact caused by measurement error. We are the first paper to consistently estimate the Dunning–Kruger effect using an instrumental variable approach. In the context of exam grade predictions of economics students, we use students’ grade point average as an instrument for their skill. Our results support the existence of the Dunning–Kruger effect.<p> |

Abstract: | Economic uncertainty has to do with the consequences of actions under different circumstances. This raises two questions: First, how sensitive are the outcomes of actions to variations in the environment? Second, how clearly can we distinguish between environments? Robustness comes at the price of targeting actions less narrowly to specific conditions, so we lose gains from specialization. Need for robustness comes from our limited knowledge. Rational dealing with uncertainty requires to accord the degree of specialization to the reliability of knowledge about the relevant circumstances. In practical terms, under such an approach acting under uncertainty is related to guidelines for strategic thinking: Focus on priorities on a broader scale; the most refined set of actions is not always the best one. |
