We analyze the effects of CEOs' layoff risk on their risk choice while overseeing a firm. A CEO, whose managerial ability is unknown, is fired if her expected ability is below average. Her risk choice changes the informativeness of output and market's belief about her ability. She can decrease...

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...

One of the main obstacles for successful economic development is the formation of institutional traps, inefficient yet stable norms of behaviour. Domination of barter exchange, arrears, corruption and black market activities are examples of institutional traps that have hampered reforms in...

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...

Any legislative framework is likely to generate different institutions or norms of behavior which the legislator occasionally could have never foreseen. I suggested a general pattern, on which inefficient, if stable, norms or institutions called institutional traps would form.

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...

What is the influence of syndicate organization on the duration of loan arrangement? I answer this question using the survival analysis methodology on a sample of loans from 59 countries over the 1992-2006 period. I find that syndicate size, concentration, reputation, and national diversity...

The theory of institutional traps, i.e. ineffective but stable institutions or behavior norms, is develope din connection with economic reforms. Mechanisms are described that cause a system to get into a trap and ways of going out of it are analyzed. Concepts of transformation costs and...
