This paper provides first and second-order approximation methods for the solution of nonlinear dynamic stochastic models in which the exogenous state variables follow conditionally-linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

We solve the problem of a social planner who seeks to minimize inequality via transfers with a fixed public budget in a distribution of exogenously given incomes. The appropriate solution method depends on the objective function: If it is convex, as in the case of the absolute mean deviation, it...

This paper shows how a dynamic multisector equilibrium model can be foraulated to be able to analyze the optimal borrowinG policy of a developing country. It also describes how a non-linear programming model with the proposed features was constructed for Brazil. And discusses the optinal...
