Este artículo analiza el problema de un planificador benevolente que desea controlar una población de agentes heterogéneos sujetos a perturbaciones idiosincrásticas. Esto es equivalente a un problema de control determinista en el que la variable de estado pertinente es la distribución de...

We recast the Aiyagari-Bewley-Huggett model of income and wealth distribution in continuous time. This workhorse model – as well as heterogeneous agent models more generally – then boils down to a system of partial differential equations, a fact we take advantage of to make two types of...

The benefits of new technologies accrue not only to high-skilled labour but also to owners of capital in the form of higher capital incomes. This increases inequality. To make this argument, we develop a tractable theory that links technology to the personal income and wealth distributions –...

We develop an efficient and easy-to-use computational method for solving a wide class of general equilibrium heterogeneous agent models with aggregate shocks, together with an open source suite of codes that implement our algorithms in an easy-to-use toolbox. Our method extends standard...
