Abstract
The notorious ‘dual stability’ paradox is stated as follows: in a closed dynamic Leontief model, when the quantity system is relatively stable, its corresponding price system will be unstable, and vice versa. This paradox arises from the neoclassical assumptions of full utilization of capacity and perfect foresight, which have caused serious complications in the dynamic Leontief model. In this study, we aim to construct a dynamic input–output model within an evolutionary framework, departing from neoclassical assumptions. Two new assumptions are introduced: incomplete utilization of capital stocks and bounded rationality in decision-making. Our findings reveal that the ‘dual stability’ paradox of the quantity and price systems can be addressed by including these two assumptions, and some special conditions are proposed for the stability properties in both the systems. Furthermore, we prove that the distance between the time paths and equilibrium position converges to a constant, which is related to the initial position.
期刊介绍:
The Evolutionary and Institutional Economics Review (EIER) is issued by the Japan Association for Evolutionary Economics to provide an international forum for new theoretical and empirical approaches to evolutionary and institutional economics. EIER, free from the view of equilibrium economics and methodological individualism, should face the diversity of human behavior and dynamic transformation of institutions. In EIER, “economics” is used in its broadest sense. It covers areas from the classic research in economic history, economic thought, economic theory, and management science to emerging research fields such as economic sociology, bio-economics, evolutionary game theory, agent-based modeling, complex systems study, econo-physics, experimental economics, and so on. EIER follows the belief that a truly interdisciplinary discussion is needed to propel the investigation in the dynamic process of socio-economic change where institutions as emergent outcomes of human actions do matter. Although EIER is an official journal of the Japan Association for Evolutionary Economics, it welcomes non-members'' contributions from all parts of the world. All the contributions are refereed under strict scientific criteria, although EIER does not apply monolithic formalistic measure to them. Evolution goes hand in hand with diversities; this is also the spirit of EIER. Focus areas of the Review (not exhaustive): - Foundations of institutional and evolutionary economics - Criticism of mainstream views in the social sciences - Knowledge and learning in socio-economic life - Development and innovation of technologies - Transformation of industrial organizations and economic systems - Experimental studies in economics - Agent-based modeling of socio-economic systems - Evolution of the governance structure of firms and other organizations - Comparison of dynamically changing institutions of the world - Policy proposals in the transformational process of economic life
