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...

This paper analyzes economic policies in resource rich countries and various mechanisms of resource curse leading to a potentially inefficient use of resources. Arguments are provided in favor of "conditional resource curse" hypothesis: resource abundance hampers growth if institutions of a...

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...

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...

A simple model of imitation and innovation is developed to explain a complicated picture of relative productivity growth in different countries. The model makes difference between global and local innovations and does not assume that a country always imitates the most advanced technology. It is...

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

A simple model of technological imitation and innovation is developed to explain club convergence in the evolution of the distribution of per-capita GDP over countries. Two versions of the model are studied and compared. The first one includes only innovation-imitation tradeoff, and the second...

If imperfect market institutions prevail in a country and inflation amounts to about 10% then efforts directed to further inflation decrease would probably hamper economic growth. To substantiate this thesis, I make references on opinions of well-known economists, discuss results of recent...

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...

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...
