This contribution concerns models and theories of structural economic dynamics. The theories and models analyzed in the paper follow two different approaches, circular and vertical, in the analysis of structural dynamics. The content of this contribution is essentially methodological. This work...

Herbert Simon (1962) has treated the notion of complexity arguing that hierarchy is clearly an essential feature of complex systems. Yet, Simon states that the systems are not organized in a hierarchy in a simple way, because if they were, would be fully decomposed, while they are "nearly...

We propose an evolutionary equation and develop an asymptotic theory that generalize results obtained in Polterovich, Khenkin, 1988. It is shown that, as a result of interaction between innovation and imitation, the shape of the efficiency distribution curve of technologies eventually...

The paper is devoted to investigation of a number of difference-differential equations, among them the following one plays the central role: dFn/dt=φ(Fn)(Fn-1 - Fn) (*) where, for every t, {Fn(t), n = 0, 1, 2, ...} is a probability distribution function, and φ is a positive function on [0, 1]....

This paper studies the evolution of the distribution of firms in the ferrous metals industry by efficiency levels. The proposed model takes into account interaction of processes of creation and adoption of technologies and depreciation of assets. It is shown that the model approximates real data...

We propose a difference-differential equation that reflects interactions between innovation and imitation processes to describe the evolution of the distribution curve of firms by efficiency levels. An explicit solution of this equation is obtained for arbitrary finite initial conditions. It is...

Structural analysis is the main topic of this paper and structural change is a dominant theme of the present work. The analysis of structural models and of theories of structural changes carried out in this paper has a double meaning. On the one hand, it allows to pick up several essential...

The study of structural changes is the theme of this work, where structural changes are correlated primarily with changes in the structure of production, which are caused by the evolution of technical progress and organizational changes in production. The analysis of models and theories of...

Structural change indicates essentially a qualitative transformation and evolution of the economic systems, usually marked by technological progress and organizational changes. Technological factors, knowledge, institutions are all elements that contribute to the process of structural change....

The concepts of absorptive capacity and innovative capability have been introduced to describe abilities of a country to imitate and, accordingly, to create more advanced technologies. In this paper we suggest new indicators of these two abilities. To calculate them, we develop an endogenous...
