A density matrix first principles formalism is extended for use in coupled dynamical systems within the framework of the Zwanzig projection operator technique. Coupled linear integro-differential equations for the reduced density operators of two (or more) dynamical subsystems interacting with...

We argue that the quality of institutions that enforce contracts and protect property rights influences the costs of producing high-value added (complex) versus low-value added (simple) products. Since data is hardly available for domestic transactions, we generate predictions about the...

Governments that privatize state industries often retain control over key distribution assets. While there are many examples of this form of partial privatization, to our knowledge there are no substantial quantitative studies of how governments use their control under these circumstances. In...

Differences in the evolution of income distribution in Poland and Russia in the post-socialist era are striking: for example, in Poland, the gini coefficient on earnings went from 0.28 to 0.33 between 1988 and 1998 while in Russia it went from 0.27 to 0.47 (UNICEF, 2001). We argue that these...

In the process of implementing market reforms, many post-socialist countries have struggled to preserve economic and political integration. Using a statistical model of commodity trade, we quantify the evolution of economic integration observed among regions within Russia during 1995-1999, and...

Working with 110 pairs of time series of state and market commodity prices in Russia, we search for signs of transition in Russia from a command to a market economy. Beginning with inter-city comparisons of state and market prices, we find that differences in the levels of these prices have...

In pursuit of its transition from a command to a market economy, post-Soviet Russia has witnessed enormous regional differences in economic growth rates. Moreover, the economic reforms implemented under this transition, while initiated at the federal level, have also differed markedly across...

A growing body of national-level survey evidence indicates that small-scale entrepreneurial activity has been an important engine of growth in post-socialist economies. Here we use a rich regional data set to obtain a statistical characterization of the relationship between entrepreneurial...
