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...

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...

Economic growth data does not show how such growth was achieved. Was it based on income growth and consumption spending levels or was it based on borrowings to extend the income levels? The question is vital for deciding which economic tools work best for correcting imbalances. The main...

An Income Gap Theory and it effects on Unemployment and Economic Growth By Drs Kees De Koning Abstract An income gap is often described as the difference in incomes between the rich and poor. This is a relative gap. In economies a different income gap can occur which can be defined as the...

Abstract Debt, equity and income: limits to the freedom of choice in an economy. Three concepts have been introduced in this paper, which help explain the economic developments in the U.S. and the U.K. over the last sixteen years; they are the “income gap”, the “equity gap” and the...

Individual households save out of income by postponing consumption. Such savings are used not only by companies to expand production or by some individual households to increase consumption through borrowings: the economic use of savings. For instance in the U.S. in 2005 and 2006 65.5% of the...

Financial sector companies are different from those in the real sector. In the real sector the price for consumer goods and services is a price reflecting all costs which have been made to produce the output. Profits reflect the difference between the sales price and the costs base. The...
