Wealth inequality is an important matter for economic theory and policy. Ongoing debates have been discussing recent rise in wealth inequality in connection with recent development of active financial markets around the world. Existing literature on wealth distribution connects the origins of...

Let V(t,x), be a time-space stationary d-dimensional Markovian and Gaussian random field given over a probability space . Consider a diffusion with a random drift given by the stochastic differential equation , x(0)=0, where w(·) is a standard d-dimensional Brownian motion defined over...

We consider [backward difference][phi] interface model on a hard wall. The hydrodynamic large-scale space-time limit for this model is discussed with periodic boundary by Funaki et al. (2000, preprint). This paper studies fluctuations of the height variables around the hydrodynamic limit in...
