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]....

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 article is devoted to the study of the history of the Soviet school of economics and mathematics, its struggle with the official ideology and attempts to influence the choice of strategies of socio-economic development. During the NEP period in the USSR a pleiad of brilliant economists...

The concept of the VAN- consortium is introduced. It is a consortium, distinguished by two specific features. Firstly, it includes a group of enterprises that carry out successive stages of production of one or more products. Secondly, the tasks of a VAN- consortium include the development and...

There are two innovations in the paper as compared to the previous literature on democracy and growth. First, we consider not only the level of democracy, but also changes in this level in the 1970s-1990s as measured by increments of Freedom House political rights indices. Second, the...

In this paper we analyze data on sustainability of democratic regimes in resource rich countries and suggest a model to explain why resource abundance may lead to instability of democracy in some countries, but does not create any difficulties for a democratic system in other ones. Rate of...

This work is devoted to the pharmacoeconomic analysis of the results of the introduction of early (preclinical) diagnosis of Parkinson's disease in Russia. On the basis of a combination of socio-economic determinants and a panel of blood biomarkers, it may be possible to identify among the...

This article contains a pharmacoeconomic analysis of early (preclinical) diagnosis of Parkinson's disease in Russia. Previous works show that using a combination of socio-economic determinants and a panel of blood biomarkers one may distinguish a Parkinsonism-related “risk group” among the...

We set and solved the problem of identifying socio-economic determinants of Parkinson's disease (PD) by comparing the characteristics of different countries. Econometric analysis of panel data on 117 countries for 2010-2013 showed that the nature of the impact of a number of factors depends on...
