In our previous papers (Polterovich V., Popov V., 2007; Polterovich V., Popov V., Tonis A., 2006) it was shown that democratization (increase in the political rights index of the Freedom house in 1970-2000) can negatively affect economic growth, if the quality of institutions at the beginning of the...

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 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...
