چکیده

The cobweb model of competitive market dynamics has been examined in the form of system dynamics model. The classical formulation of the cobweb demand-supply model has been transformed in the set of equations suitable for system dynamics modelling. The model has been expanded by the time parameter ∆t which enables the stability analysis of the model for the change in the ∆t. The structure of the model has been presented and key relationships in the model have been examined. The cyclical response of the system which is dependent on the demand∼supply parameters and eigenvalues of the characteristic equation has been numerically examined.

Cobweb Chaos in Agricultural Markets: Simulation Results

This study augments the traditional linear cobweb model with lower and upper bounds for variations of output. Its purpose is to detect the relationship between the output constraints and the dynamics of the modified model. Due to the upper and lower bounds, a transitional function takes on a tilted z-profile having three piecewise segments with two turning points. It prevents the price (or quan...

Complex Price Dynamics in Vertically Linked Cobweb Markets in Less Developed Countries

Advances in nonlinear dynamics have resuscitated interest in the theory of endogenous price fluctuations. In this paper, we enrich the traditional cobweb model by incorporating vertical linkages between agricultural markets, an important aspect of agricultural production in less developed countries that has been largely ignored by the existing literature on chaotic cobweb models. To this end, u...

Replicator Dynamics in a Cobweb Model with Rationally Heterogeneous Expectations

This paper extends the Adaptively Rational Equilibrium Dynamics (ARED) of (Brock and Hommes 1997) by introducing a generalized version of the replicator dynamic of (Sethi and Franke 1995). The Replicator Equilibrium Dynamics (RED) couples the price dynamics of a cobweb model with predictor selection governed by an evolutionary replicator dynamic. We show that the RED supports the main conclusio...

An Analysis of the Cobweb Model with Boundedly Rational Heterogeneous Producers

ABSTRACT. This paper studies the dynamics of the traditional cobweb model with risk averse heterogeneous producers who seek to learn the distribution of asset prices using geometric decay processes (GDP)—the expected mean and variance are estimated as a geometric weighted average of past observations—with either finite or infinite fading memory. With constant absolute risk aversion, the dynamic...

Stability analysis of a cobweb model with market interactions

This paper explores the steady-state properties and the dynamic behavior of a generalization of the classical cobweb model. Under fairly general demand and cost functions, producers form naïve expectations about future prices and select their output so as to maximize expected profits. Unlike the traditional setup, producers have the choice between two markets, and tend to enter that which was m...
