Inequality and debt in a model with heterogeneous agents [PDF]

Economics Letters, 2014
We show that to account for the cross-sectional divergence in debt-to-income ratios in US data a DSGE model must assume a tax reallocation across the top- and bottom-income quantile of the population, rather than differential productivity growth, and low cost of access to financial intermediation.

A Behavioral Heterogeneous Agent New Keynesian Model

SSRN Electronic Journal, 2022
We develop a New Keynesian model with household heterogeneity and bounded rationality in the form of cognitive discounting. The interaction of household heterogeneity and bounded rationality generates amplification of monetary and fiscal policy through indirect general equilibrium effects while simultaneously ruling out the forward guidance puzzle and ...

A dynamic exchange rate model with heterogeneous agents [PDF]

Journal of Evolutionary Economics, 2017
In this paper, we analyze a heterogeneous agent model in which the fundamental exchange rate is endogenously determined by the real markets. The exchange rate market and the real markets are linked through the balance of payments. We have analytically found that there exists at least a steady state in which the exchange rate is equal to its fundamental

Modelling Heterogeneity in Multi Agent Systems

2002
The aim of this paper is to consider the issue of heterogeneity in modelling complex systems through a multi agent perspective. Complex systems are often characterized by a high degree of heterogeneity of the involved components and by their natural aggregation in communities representing different views of the same system.

Essays on heterogeneous agent models

2023
The thesis consists of three chapters. The first chapter examines the behaviour of the New Keynesian (NK) model, which has been extended to include heterogeneous individuals who face idiosyncratic productivity risk. My main focus in this chapter is the heterogeneity innovation of the model, therefore, I consider the relatively simple NK setting where ...

Heterogeneous Agent Models

AEA Papers and Proceedings
Heterogeneous agent models have become central to modern macroeconomic research, often replacing the representative agent framework. However, what is core for these frameworks is the use of microfoundations that involve optimizing behavior. The strength of heterogeneous agent models lies in their ability to address questions where heterogeneity is ...

Lumpability of fluid models with heterogeneous agent types

2013 43rd Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2013
Fluid models have gained popularity in the performance modeling of computing systems and communication networks. When the model under study consists of many different types of agents, the size of the associated system of ordinary differential equations (ODEs) increases with the number of types, making the analysis more difficult.

Identification in Heterogeneous Agent Models

SSRN Electronic Journal, 2019
Many representative agent macro models suffer from parameter identification failure. These issues extend to the structural parameters of the standard incomplete markets model of Aiyagari (1994), the workhorse heterogeneous agent model for household and firm behavior.
