In this paper, we provide solution methods for non-linear rational expectations models in which regime-switching or the shocks themselves may be "endogenous," i.e. follow state-dependent probability distributions. We use the perturbation approach to find determinacy conditions, i.e. conditions...

Starting with J. Muth’s unsupported and unsupportable claims, originally made in 1961, that “rational expectations” were subjective probability distributions that were distributed around a known, true, objective probability distribution, various economists have provided the same type of...

We study a small open economy displaying Pareto-distributed wealth resulting from random death. The government runs a distribution scheme on inheritance. We present the mathematical background that allows to study the dynamics of means. We end up with ordinary differential equations for the mean...

The paper analyzes the joint evolution of accumulation and distribution of human capital in an OLG framework. Dynamics arise from the interplay between human capital distribution and individual variables--inherited human capital and inborn ability. Such interaction drives individual investment...
