The role of information in economic dynamics is examined. A misconception that the removal of uncertainty always brings additional stability to an existing equilibrium is clarified. It is shown that the relation between information and equilibrium stability is not monotonic. Removing information...

Adaptive behavior has been observed in almost all aspects of real-world. One of the main advantages of acting adaptively is its stabilizing effect on dynamic equilibrium, associated with which are three favorable features: (a) non-destabilizing characteristics, (b) low-speed effectiveness and...

In this paper we examine various types of financial crises and conjecture their underlying mechanisms using a deterministic heterogeneous agent model (HAM). In a market-maker framework, forward-looking investors update their price expectations according to psychological trading windows and...

Price‐taking has long been mistakenly regarded as an inferior firm behavior in an imperfectly competitive market. This scenario is challenged when a “Naiver’s Paradox” is shown to exist in an oligopolic market where all firms produce the same product with the same technology (cost...

The advantage of price-taking behavior in achieving relative profitability in oligopolistic quantity competition has been much appreciated recently from economic dynamics and evolutionary game theory, respectively. The current research intends to provide a direct economic interpretation as well...

In a quantity-competed duopoly, one firm is a naive price-taker (who responses only to the last period’s price) while the other has all the market information so as be able to optimize its profit stream (either discounted or un-discounted) dynamically over a finite or infinite horizon. With a...

Tests and estimation for changes in the coefficients of linear regression models, particularly the analysis of covariance and the Chow tests, are well known to econometricians and are widely used. This paper demonstrates that analogous estimation can also be constructed in simultaneous equation...
