We introduce a novel concept, group image concerns, showing that individuals change their behavior and are willing to incur personal costs to cultivate a positive image of their groups. We develop an experimental method to identify and quantify group image concerns, and conduct a series of...

An effective way to foster cooperation is to monitor behaviour and sanction freeriding. Yet, previous studies have shown that cooperation quickly declines when sanctioning mechanisms are removed. We test if explicitly expressing trust in players' capability to maintain cooperation after the...

In this paper we attempt to compare theoretically and experimentally three models of strategic information transmission. In particular we focus on the models by Crawford & Sobel (1982), Lai (2010) and Ehses-Friedrich (2011). These three models differ in the information that the receiver...

Large Language Models (LLMs) have the potential to profoundly transform and enrich experimental economic research. We propose a new software framework, "alter_ego", which makes it easy to design experiments between LLMs and to integrate LLMs into oTree-based experiments with human subjects. Our...

The organization of work and the characteristics of tasks have undergone considerable changes in recent years. The developments include (i) an increased relevance of virtual teams and (ii) a higher demand for non-routine tasks in organizations, including creativity. Existing research on creative...

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...

We explore in an experiment what leads to the breakdown of partnerships. Subjects are assigned a partner and participate in a repeated public good game with stochastic outcomes. They can choose each period between staying in the public project or working on their own. There is excessive exit as...

We run a market experiment where firms can choose not only their price but also whether to present comparable offers. They are faced with artificial demand from consumers who make mistakes when assessing the net value of products on the market. If some offers are comparable however, some...
