Transparency and accountability are often regarded as crucial for good governance and the efficient organization of public affairs. To systematically explore the impact of transparency and accountability on cooperation, we conduct a series of laboratory experiments on a variation of the public...

We provide experimental evidence on the emergence of redistributive societies. Individuals first vote on redistribution by feet and then learn their productivity and invest. We vary the individuals’ information about their productivities at the time when they choose a distribution rule and...

This article analyzes experimentally whether the degree of collusion for one dimension of duopolists’ interactions influences the degree of collusion for another dimension. More precisely, I will explore whether a high degree of collusion for advertisement expenditures facilitates tacit price...

hroot (Hamburg Registration and Organization Online Tool) is a web-based software designed for managing participants of economic experiments. This package provides important features to assure a randomized invitation process based on a filtered, pre-specified subject pool, and a complete...

Broken windows: the metaphor has changed New York and Los Angeles. Yet it is far from undisputed whether the broken windows policy was causal for reducing crime. The scope of the theory is not confined to crime. The theory claims that crime is inextricably linked to social order more generally....

Laboratory experiments by Fudenberg and Pathak (2010), and Vyrastekova, Funaki and Takeuch (2008) show that punishment is able to sustain cooperation in groups even when it is observed only in the end of the interaction sequence. Our results demonstrate that the real power of unobserved...

This study investigates the dynamic efficiency of an emission regulation regime where companies competitively pay for emission licences. We embed the emission licence market in a Cournot model where the price of emission licences is subject to strategic tradeoff between licences and abatement...

The price mecanism is the primary means of information transfer in decentralized economic systems. High prices indicate high demand, whereas low prices indicate low demand. Thus prices are the signals for accelerating or slowing production. However, using sequential, multi-unit auctions, we show...

For given product specifications by two competing firms the demand levels are determined by a randomly generated ideal composition of aspects. Firms can vary some demand. Although the product space is much too large to be explored systematically, we expect (and test for) rather reasonable...
