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...

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...

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...

We suggest a dynamic game theoretic model to explain why resource abundance may lead to instability of democracy. Stationary Markov perfect equilibria of this game with four players – Politician, Oligarch, Autocrat and Public (voters) – are analyzed. Choosing a rate of resource rent tax,...

We analyze data on sustainability of democratic regimes in resource rich countries and suggest a two-period model to explain why resource abundance may lead to instability of democracy in some countries, but does not create any difficulties for democratic system in other ones. Our central idea...

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 report focuses on the regional system of innovation in małopolskie voivodeship (southern Poland). It presents the results of two empirical stages. The first stage was conducted using computer assisted telephone interviews (CATI) on the sample of 465 enterprises and 51 business support...

The SME sector is one of the factors that contribute to economic growth in every country on the national and regional level, and it holds true to Poland and Slovakia. Although this sector grew most rapidly during the beginning transition period, it still retains its significant role in the...
