This paper is concerned with the optimal switching problem, dynamics of which McKean-Vlasov diffusions and criterion a function law state process. A remarkable new feature in this setting that time also impacts process through dependence coefficients on law. The mean field problem introduced weak formulation terms joint marginal specification satisfies dynamic programming principle, correspondi...

In this paper, a test procedure based on Gini’s mean difference for testing homogeneity of scale parameters against umbrella ordered alternative with at least one strict inequality, when peak of the umbrella is known, is proposed. The exact critical points through simulation are computed for the proposed test in case of standard exponential, standard logistic and standard uniform distributions;...

Abstract We analyze a political competition model of redistributive policies. provide an equilibrium existence result and full characterization the net transfers to different income groups. also derive several testable predictions about way in which group after-tax Gini coefficient vary with main parameters model. In accordance theory, empirical evidence from sample developed developing democra...
