Interest in prediction markets has increased in the last decade, driven in part by the hope that these markets will prove to be valuable tools in forecasting, decision-making and risk management - in both the public and private sectors. This paper outlines five open questions in the literature,...

We provide evidence that long-term relationships between trading parties emerge endogenously in the absence of third party enforcement of contracts and are associated with a fundamental change in the nature of market interactions. Without third party enforcement, the vast majority of trades are...

Within a laboratory experiment we investigate a principal-agent game in which agents may, first, self-select into a group task (GT) or an individual task (IT) and, second, choose work effort. In their choices of task and effort the agents have to consider pay contracts for both tasks as offered...

What is the motivational effect of imposing a minimum effort requirement? Agents may no longer exert voluntary effort but merely meet the requirement. Here, we examine how such hidden costs of control change when control is considered legitimate. We study a principalagent model where control...

This study explores the effect of several personal religion-related variables on social behaviour, using three paradigmatic economic games: the dictator (DG), ultimatum (UG), and trust (TG) games. A large carefully designed sample of a Spanish urban adult population (N=766) is employed. From...

We show experimentally that a principal’s distrust in the voluntary performance of an agent has a negative impact on the agent’s motivation to perform well. Before the agent chooses his performance, the principal in our experiment decides whether he wants to restrict the agents’ choice set...

In recent years, many social scientists have claimed that trust plays an important role in economic and social transactions. Despite its proposed importance, the measurement and the definition of trust seem to be not fully settled, and the identification of the exact role of trust in economic...

We run a novel experiment to explore the relationship between the perception of real-life risks and the demand for risk reduction. Subjects play a series of loss lotteries in which the odds are matched to the likelihood of lethal events in real life. For each risk, subjects can pay premiums in...

This paper discusses the choice of the number of participants for within-subjects (WS) designs and between-subjects (BS) designs based on simulations of statistical power allowing for different numbers of experimental periods. We illustrate the usefulness of the approach in the context of field...

The goal of this paper is to examine stability in preferences using the Stigler-Becker state-dependent framework. Using a randomized intervention that changes the opportunity sets of individuals we construct a unique panel data from an artefactual field experiment and evaluate whether the change...
