Population-ageing is one of the traditional topics of development and growth theory and a key challenge to most modern societies. We focus on the following aspect: Population-ageing is associated with changes in demand-structure, since demand-patterns change with increasing age. This process...

The Kuznets-Kaldor stylized facts are one of the most striking empirical regularities of the development process in industrialized countries: While massive factor reallocation across technologically distinct sectors takes place, the aggregate ratios of the economy are quite stable. This implies...

Different goods are produced by different sectors in an economy. The fact that sectors use different production technologies is named technology-bias. The technology-bias is well documented and has important theoretical implications for economic growth and unemployment. We provide a theoretical...

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...

We propose a model for studying the dynamics of economic structures. The model is based on qualitative information regarding structural dynamics, in particular, (a) the information on the geometrical properties of trajectories (and their domains) which are studied in structural change theory and...

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...

Recent growth literature studies structural change in relatively specific three-sector growth models with a focus on the agriculture-manufacturing-services structure. In this paper we take another approach for studying this structural change. By using only few axioms on the properties of...
