In most economics textbooks there is a gap between the non-existence of utility functions and the existence of continuous utility functions, although upper semi-continuity is sufficient for many purposes. Starting from a simple constructive approach for countable domains and combining this with...

This paper presents a methodology to determine the preferences of an individual facing risk in the framework of (non)-expected utility theory. When individual preference satisfies a given invariance property, his utility function is solution of a functional equation associated to a specific...

This article analyses through a rent seeking model, the relationship between institutions' quality and natural resources. Depending on the institutions quality, each country has a specific structural capacity to stand natural resources dependency. It is shown that for each country, a threshold...

In this paper, we present a rent-seeking model of conflict, which highlights the role of ideology in determining whether the government or the rebels take the initiative. We use the model to interpret the impact of a large-scale Community-Driven Development project on civil conflict in the...

The Word Summit on Sustainable Development (Johannesburg, 2002) encouraged the application of the ecosystem approach by 2010. In this perspective, we propose a theoretical management framework that deals jointly with i) ecosystem dynamics, ii) conflicting issues of production and preservation...

We consider a framework à la Wirl (1994) where political liberalization is the outcome of a lobbying differential game between a conservative elite and a reformist group, the former player pushing against political liberalization in opposition to the latter. In contrast to the benchmark model,...

In this chapter, we propose a primer of the treatment that has received in the economic literature the problematic of entrepreneurship and rent-seeking behavior. It comprises the introduction of employed concepts, the discussion of the allocation of entrepreneurs between different types of...

Evidence shows that the allocation of talented people is not neutral for growth. Thus, a country with a large population of law concentrators tends to develop rent-seeking activities that reduce growth. A country with a large population of engineers tends to foster innovation and strengthen...

We develop a new mechanism through which skilled migration may influence economicperformance in the sending country. If agents can choose between acting asrent-seekers and engaging in productive activities, and only productive skills are exportable,a positive probability of migration (to a more...
