Heterogeneous Agent Models: Two Simple Case Studies

Hommes, Cars - 2005

These notes review two simple heterogeneous agent models in economics and finance. The first is a cobweb model with rational versus naive agents introduced in Brock and Hommes (1997). The second is an asset pricing model with fundamentalists versus technical traders introduced in Brock and...

Heterogeneous Agent Models in Economics and Finance

Hommes, Cars H. - 2005

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...

Stationarity and Ergodicity of Univariate Generalized Autoregressive Score Processes

Blasques, Francisco; Koopman, Siem Jan; Lucas, Andre - 2012

We characterize the dynamic properties of Generalized Autoregressive Score (GAS) processes by identifying regions of the parameter space that imply stationarity and ergodicity. We show how these regions are affected by the choice of parameterization and scaling, which are key features of GAS...

The Good, the bad, and the ugly: an inquiry into the causes and nature of credit cycles

Matsuyama, Kiminori - 2004

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth and uses them to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Bad is highly productive, but, unlike the Good, it...
