We provide a simple theoretical foundation, based on the theory of Markov chains, for the objective empirical procedure for journal ranking devised by Liebowitz and Palmer.An elementary characterization is derived that substantially clarifies the meaning, scope and underlying intuition of the...

In this paper we investigate wealth inequality/polarization properties related to the support of the limit distribution of wealth in innovative economies characterized by uninsurable individual risk. We work out two simple successive generation examples, one with stochastic human capital...

In this paper we study the geometrical properties of the support of the limit distributions of income/wealth in economies with uninsurable individual risk, and how they are affected by technology and preference parameters and by policy variables. We work out two simple successive generation...
