We discuss possible criteria that may qualify or disqualify power indices for applications. Instead of providing final answers we merely ask questions that are relevant from our point of view and summarize some material from the literature

Opinion is divided on whether it is better to have a single world money or variable exchange rates.Pope, Selten and von Hagen (2003) propose that fresh light would be shed via an analysis that allows forseven complexity impacts on the exchange rate that are underplayed (where not entirely...

A modelling strategy that accounts for measurement outside the laboratory, where one cannot base measurements on a single simple law, will have to drop the requirement that the model is a homomorphic mapping of the empirical relational structure. The model used for measurement will be a...

This paper presents an experimental study that compares the ability of human groups to escape the tragedy of the commons through institutional change or communication. Teams of five players are placed in a dynamic CPR environment with inefficient institutional settings. The results clearly show...

The sanctioning of norm-violating behavior by an effective formal authority is an efficient solution for social dilemmas. It is in the self-interest of voters and is often favorably contrasted with letting citizens take punishment into their own hands. Allowing informal sanctions, by contrast,...

We report a controlled laboratory experiment examining risk-taking and information aggregation in groups facing a common risk. The experiment allows us to examine how subjects respond to new information, in the form of both privately observed signals and signals reported from others. We find...

We investigate the potential of transparency to influence committee decision-making. We present a model in which career concerned committee members receive private information of different type-dependent accuracy, deliberate and vote. We study three levels of transparency under which career...

In experimental investigations of the effect of real incentives, accountability-the implicit or explicit expectation of a decision maker that she may have to justify her decisions in front of somebody else-is often confounded with the incentives themselves. This confounding of accountability...

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare these choices to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...
