Regime-Switching Perturbation for Non-Linear Equilibrium Models∗

Salient macroeconomic problems often lead to highly non-linear models – for instance models incorporating endogenous crises or the zero-lower-bound on interest. Accurately capturing non-linearity in equilibria often makes estimation infeasible. Local solution methods are limited since they struggle to capture non-linearities, and the curse of dimensionality plagues global methods. This paper in...

General Equilibrium Asset Pricing under Regime Switching

We have investigated the asset pricing problem in a general equilibrium in an economy with two states. Based on the assumption of a CRRA utility function, we have derived a partial differential equation satisfied by the representative agent’s cost function. In the case when the representative agent doesn’t have intermediate consumption, we have found an explicit solution of the cost function. A...

Colloidal gels: equilibrium and non-equilibrium routes

We attempt a classification of different colloidal gels based on colloidcolloid interactions. We discriminate primarily between non-equilibrium and equilibrium routes to gelation, the former case being slaved to thermodynamic phase separation while the latter is individuated in the framework of competing interactions and of patchy colloids. Emphasis is put on recent numerical simulations of col...

Equilibrium and Non-equilibrium Quantum Field Theory

We first focus in Chapter 2 on infrared effects in finite–temperature quantum field theory. We propose a simple mathematical method (based on the largest–time equation and the Dyson–Schwinger equations) which allows systematic calculations of the change of density in energy/particles in heat–bath during a scattering/decay of external particles within the heat bath. A careful analysis reveals th...
