Proton number fluctuations in partial chemical equilibrium

Partial Chemical Equilibrium : Theory and Implementation in the Program

EQUILIBRIUM FLUCTUATIONS FORr ' INTERFACE

We study the large scale space{time uctuations of an interface which is modeled by a massless scalar eld with reversible Langevin dynamics. For a strictly convex interaction potential we prove that on a large space{time scale these uc-tuations are governed by an innnite-dimensional Ornstein-Uhlenbeck process. Its eeective diiusion type covariance matrix is characterized through a variational fo...

Equilibrium Unemployment Fluctuations∗

This paper develops three facts about the cyclical behavior of the labor market in the U.S. and explores whether existing models are consistent with those facts. I find that a standard model of search unemployment with wage bargaining either counterfactually predicts a positive correlation between unemployment and vacancies over the business cycle or predicts an order of magnitude more wage cyc...

Fluctuations in chemical gelation.

We study a chemical gelation model in two dimensions which includes both monomer aggregations and bond fluctuations. Our numerical simulation shows that a sol-gel transition occurs when an initial monomer concentration is above a critical concentration. Fractal aggregates grow until the sol-gel transition occurs. After the gelation, however, bond fluctuations break the fractal structure and an ...

Implementation in partial equilibrium

Consider a society with a finite number of sectors (social issues or commodities). In a partial equilibrium (PE) mechanism a sector authority (SA) aims to elicit agents’preference rankings for outcomes at hand, presuming separability of preferences, while such presumption is false in general and such isolated rankings might be artifacts. Therefore, its participants are required to behave as if ...
