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...

Cheating is a serious problem in many countries. The cheater gets higher marks than deserved, thus reducing the efficiency of a country’s educational system. In this study, the authors did not ask if and how often the student had cheated, but rather what the student’s opinion was...

At the end of 2012 and the start of 2013, the Higher School of Economics and the Association of Russian Economic Think Tanks (ARETT) conducted a project devoted to modern conditions and trends in the development of think tanks as a significant segment of independent research in Russia and their...

Abstract The article deals with the basic elements of a rational strategy of economic development of Russia in the modern circumstances. The analysis shows that the current state of confrontation between Russia and the United States will last long enough. Trying to shorten the period of forced...
