Mobility and Long term Equality of Opportunity

The aim of this paper is to propose a methodology for evaluating long-term income distributions according to the equality of opportunity principle; we propose partial and complete rankings of long term income distributions and show the relationship between the inequality of oppor- tunity in the single periods of time and inequality of opportunity in the long run. We show that this relationship can be interpreted in terms of intragenerational mobility. In general, it is possible to state that mobility can act as an equalizer of opportunities when the accounting period is extended.Equality of opportunity, income mobility, inequality, social welfare

From Solvable to Executable Models of Biological Systems

Classical modeling approaches for biology are mainly grounded in mathematics, and specifically on ordinary differential equations (ODE). Process calculi-based conceptual and computational tools are an alternative and emergent approach. Here we focus our analysis on BlenX (a beta-binders inspired programming language) showing how it is possible to easily re-use ODE models within this framework. An example will show then the advantages of moving into a stochastic approach. This is the preliminary version of a paper that was published in Proceedings of Pacific Symposium on Biocomputing (PSB 2009), January, 2009.
