In this work the evolutionary dynamics of migratory behavior driven by imitation is studied. We show that, any migratory flow, driven by the imitation, can be modeled by a dynamic system, once the rules governing imitative behavior of the population, are established. The parameters...

Since the early nineties in Swedish starts a welfare state transformation process that allows the participation of private operators in sectors emblematic of the welfare state, such as education, health, child care and assistance to adults. To date, experience shows that the coexistence of...

In this paper, we consider a society composed of citizens grouped in different economic strata based on income, who must pay taxes, but there are incentives to do so, and a set of public officials (auditors), whose function is to monitor compliance with the tax rules among citizens. We assume...

One can restructure institutions, but if individual-level motivations for corrupt behavior are not understood, these restructuring may not be effective. We introduce an evolutionary-game modeling to deal with the problem of corruption driven by imitative behavior.

This paper studies the joint dynamics of corruption and pollution in a model of evolutionary game theory, where firms face a given pollution standard and the government must check the compliance to this standard by means of public officials who can be honest or not. A novelty of our paper is...

Purpose – The purpose of this paper is to examine the supernatural punishment theory. The theory postulates that religion increases cooperation because religious people fear the retributions that may follow if they do not follow the rules and norms provided by the religion....

Does religion enhance prosocial behavior? We investigate the ways in which implicit influences of religious concepts affect generosity and cooperation. In contrast to previous studies, we assess the direct impact of religion as an independent variable on prosocial behavior. We do so by...

The aim of this study is to investigate the effect of privatisation on productivity development in the Chilean potable water and sewage sector. We have access to high quality firm level data making it possible to study the effects on a firm level. Productivity development is studied by means of...
