This paper aims at showing how the use of the dynamical systems theory (dst) has affected the thematic content of economic analysis, either by fostering new theoretical developments or by making translation from economics to mathematics more complete. To this end, we elaborate a classification...

Two time delays are assumed in a boundedly rational monopoly. The characteristic equation is derived for the general case, and a complete stability analysis is conducted both analytically and numerically in two special cases. In the first case, wherein the continuously distributed time delays...

Cournot oligopolies are examined with two kinds of output adjustment costs, which model the use of contingent work force and additional investments. The best responses of the firms are first determined and the partial adjustment toward best responses is assumed in formulating a dynamic model....

The paper presents a synthesis of the economics of exhaustible resources and that of endogenous fertility in an overlapping-generations model. Renewable energy is produced by a backstop, while the consumption good is produced from energy – provided by the backstop or from a stock of...

In this paper we propose a model in which the real side of the economy, described via a Keynesian good market approach, interacts with the stock market with heterogeneous speculators, i.e., optimist and pessimist fundamentalists. Employing analytical and numerical tools, we detect the mechanisms...

We introduce in a post-Keynesian/Kaleckian model of growth and distribution a constraint on firms’ investment induced by increasing adjustment costs and/or limited financial resources. Whereas in the short run limiting firms’ investment reduces capacity utilization and capital accumulation,...

Stress fluctuations in a model of densely packed disks under steady shear reproduce many features known for complex systems. These include fat-tailed probability distributions, volatility clustering and long-range autocorrelations. Using a rescaling analysis developed in econophysics, we relate...

We develop a macroeconomic behavioral model in order to analyze the interactions between product and financial markets. The real subsystem is represented by a simple Keynesian income–expenditure model, while the financial subsystem is represented by an equilibrium stock market with...
