Heterogeneous expectations, housing bubbles and tax policy

C Martin, N Schmitt, F Westerhoff - Journal of Economic Behavior & …, 2021 - Elsevier
We integrate a plausible expectation formation and learning scheme of boundedly rational
investors into a standard user cost housing market model, involving a rental and a housing …

Production delays, technology choice and cyclical cobweb dynamics

R Dieci, S Mignot, F Westerhoff - Chaos, Solitons & Fractals, 2022 - Elsevier
We develop a cobweb model in which firms, facing a two-period production delay, have
access to a flexible (costly) and an inflexible (cheap) production technology. Moreover, firms …

Explaining the Stylized Facts of Foreign Exchange Markets with a Simple Agent-based Version of Paul de Grauwe's Chaotic Exchange Rate Model

S Mignot, F Westerhoff - Computational Economics, 2024 - Springer
We propose a simple agent-based version of Paul de Grauwe's chaotic exchange rate
model. In particular, we assume that each speculator follows his own technical and …

Necessary and sufficient conditions for the roots of a cubic polynomial and bifurcations of codimension-1,-2,-3 for 3D maps

L Gardini, N Schmitt, I Sushko… - Journal of Difference …, 2021 - Taylor & Francis
We reconsider the well-known conditions which guarantee the roots of a third-degree
polynomial to be inside the unit circle. These conditions are important in the stability analysis …

Production delays, supply distortions and endogenous price dynamics

R Dieci, S Mignot, N Schmitt, F Westerhoff - Communications in Nonlinear …, 2023 - Elsevier
It takes time to produce commodities, and different production technologies may take
different lengths of time. Suppose that firms may switch between different production …

Speculative housing markets and rent control: insights from nonlinear economic dynamics

N Schmitt, F Westerhoff - Journal of Economic Interaction and Coordination, 2022 - Springer
We propose a novel housing market model to explore the effectiveness of rent control. Our
model reveals that the expectation formation and learning behavior of boundedly rational …

Local stability conditions for a n-dimensional periodic mapping

R Luís, S Mendonça - Mathematics and Computers in Simulation, 2024 - Elsevier
In this paper we determine the necessary and sufficient conditions for asymptotically stability
of periodic cycles for periodic difference equations by using the Jury's conditions. Such …

Revisiting Paul de Grauwe's chaotic exchange rate model: New analytical insights and agent-based explorations

S Mignot, F Westerhoff - Open Economies Review, 2023 - Springer
We apply recent stability and bifurcation results to provide an analytical characterization of
Paul de Grauwe's chaotic exchange rate model. We prove that the model's fundamental …

(Ir) rational explorers in the financial jungle: Modelling Minsky with heterogeneous agents

A Cafferata, MJ Dávila-Fernández, S Sordi - Journal of Evolutionary …, 2021 - Springer
In recent decades, several scholars have formalised Minsky's profound insight that
increasing financial fragility accompanies periods of economic stability. It must be noted …

Speculative asset price dynamics and wealth taxes

S Mignot, F Tramontana, F Westerhoff - Decisions in Economics and …, 2021 - Springer
Based on the seminal asset-pricing model by Brock and Hommes (J Econ Dyn Control 22:
1235–1274, 1998), we analytically show that higher wealth taxes increase the risky asset's …
