This paper deals with the subject of third-party punishment. The paper compares, by means of an economic experiment, punishment by a third party (Stand-Alone case) with punishment by third parties (In-Group environment). This deliberate introduction of a second potential punisher is neither...

The experiment presented in this paper has two aims, both methodological. First, we want to check for the role of what we may call (after Carpenter et al., 2006) the they came to play effect. Second, we want to test whether the lab outcomes are confirmed by a questionnaire on a hypothetical...

The main activity of a welfare state is to impose taxes in order to collect money to provide services. In this paper we want to test subjects' perception of these two steps in the lab. In particular, using a real effort experiment as a tool, we aim at measuring both the labour supply and the...

The aim of this paper is to contribute to the debate about the electoral rules in Italy. In particular, we simulate some voting rules to test what is the best electoral system on the basis of a utility function that takes into account two indices: representativeness and governability. As long as...

The paper illustrates the results of some experiments aiming to test the effect of taxation on the effort. Differently from previous experiments (Levy-Garboua et al., Sutter and Weck-Hannemann, Swenson), in our research the revenue of taxation is not depleted but employed, more realistically, to...

The model by Fehr and Schmidt introduces envy and altruism in the utility function of a representative agent. The aim of this paper is to provide two extensions - non linearity and non self-centredness - to this model. This extension turns out to be more consistent with experimental evidence...

A real-effort experiment is conducted in order to detect preferences for one out of three different models of the Welfare State characterized by different tax-and-transfer schemes. We reproduce a small society in the lab where: Subjects are grouped in three stylized classes (the rich, the middle...
