In reality, it is often groups rather than individuals that make decisions. In previous experiments, groups have frequently been shown to act differently from individuals in several ways. It has been claimed that inter-group interactions may be (1) more competitive, (2) more rational, or (3)...

Often in cooperative situations, many aspects of the decision-making environment are uncertain. We investigate how cooperation is shaped by the way information about risk is presented (from description or from experience) and by differences in risky environments. Drawing on research from risky...

We study conditional cooperation based on a sequential two-person linear public good game in which a trusting first contributor can be exploited by a second contributor. After playing this game the first contributor is allowed to punish the second contributor. The consequences of sanctioning...

The determinants of risk attitude in couples are explored using data from the German Socio-Economic Panel over the period 2004 to 2009. The focus of the analysis is the repeated responses to the survey question about general willingness to take risk. Responses to this question are provided on a...

Cooperation can benefit and hurt firms at the same time. An important question then is: when is it better to cooperate. And how can an appropriate partner be selected? In this paper we present a model of inter-firm cooperation driven by cognitive distance, appropriability conditions and external...

Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

This paper explores how and why collaboration with different types of partners and the position within a research network can affect firms' innovative performance in terms of product innovations. A detailed empirical analysis is carried out in the biotechnology and pharmaceutical industry. This...

This paper experimentally investigates the effect of limits on campaign spending and outcome in an electoral contest where two candidates, an incumbent and a challenger, compete for office in terms of the amount of campaign expenditure. The candidates are asymmetric only in that the incumbent...

One of the top priorities to improve the European Union's growth performance is the creation ofsingle market for services. The directive on services adopted by the Parliament and the Council by the end of 2006 aims at removing barriers to the free movement of service providers on the internal...

We investigate the theoretically proposed link between judgmental overconfidence and trading activity. In addition to applying classical measures of miscalibration, we introduce a measure to capture misperception of signal reliability, which is the relevant bias in the theoretical overconfidence...
