Carl's nonlinear cobweb

C Hommes - Journal of Economic Dynamics and Control, 2018 - Elsevier
This essay surveys some of my work on expectations, learning and bounded rationality
within the classical cobweb model following early inspiring ideas from Carl Chiarella. In …

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 …

Side effects of nonlinear profit taxes in an evolutionary market entry model: abrupt changes, coexisting attractors and hysteresis problems

N Schmitt, J Tuinstra, F Westerhoff - Journal of Economic Behavior & …, 2017 - Elsevier
In order to demonstrate that nonlinear tax systems may have surprising and potentially
undesirable side effects, we develop an evolutionary market entry model in which firms …

Piecewise-linear maps and their application to financial markets

F Tramontana, F Westerhoff - Frontiers in Applied Mathematics and …, 2016 - frontiersin.org
The goal of this paper is to review some work on agent-based financial market models in
which the dynamics is driven by piecewise-linear maps. As we will see, such models allow …

Bifurcation structures of a two-dimensional piecewise linear discontinuous map: analysis of a cobweb model with regime-switching expectations

L Gardini, D Radi, N Schmitt, I Sushko, F Westerhoff - Nonlinear Dynamics, 2024 - Springer
We consider the bifurcations occurring in a two-dimensional piecewise-linear discontinuous
map that describes the dynamics of a cobweb model in which firms rely on a regime …

Production delays and price dynamics

C Hommes, K Li, F Wagener - Journal of Economic Behavior & …, 2022 - Elsevier
This paper develops a unified analysis of the impacts of production delays on aggregate
price fluctuations in a continuous-time cobweb-type model. We find that the time …

Interacting Cobweb Demands

L Pinna, G Ricchiuti - Computational Economics, 2024 - Springer
This paper proposes a simple, stylized two-good, two-market dynamical cobweb model.
Consumers and producers are located in two countries, where they can choose to consume …

Nonlinear asset-price dynamics and stabilization policies

N Schmitt, F Tramontana, F Westerhoff - Nonlinear Dynamics, 2020 - Springer
We first present a brief review of nonlinear asset-pricing models and contributions in which
such models have been used as benchmarks to evaluate the effectiveness of a number of …

Oligopoly game: Price makers meet price takers

M Anufriev, D Kopányi - Journal of economic dynamics and control, 2018 - Elsevier
The paper studies an oligopoly game, where firms can choose between price-taking and
price-making strategies. On a mixed market price takers are always better off than price …
