The article deals with variables structure. A summary of dependence trees and graphical models with a special em-phasis on Dempster covariance selection method in part one is followed in the second part by a description of a modi-fication of the latter developed by the author. An application of...

The second part of the article continues studying the structure of a set of variables. It consists of two pieces: (1) de-scription of a modification of Dempster covariance selection algorithm based on its combination with that of tree dependence structures construction, simulation results,...

What do foreign companies take into account when they invest in Russian food industry enterprises? The sample of about 5000 enterprises of the food industry from different Russian regions is analyzed to give the answer to this question. The most interesting points for the investigation are...

Using the Ross tat panel data for the 2001–2008 period we estimate the gravity model of migration between Russian regions. We show that though the migration flows have been quite stable, their determinants have changed substantially. Special attention is drawn to the role of distance between...

Taking the law of one price as a test for market integration, the spatial structure of Russia’s market integration is analyzed with the use of time series of consumer goods prices across Russian regions. An effort is made to explain the pattern obtained, identifying forces responsible for...

The present study suggest a generalization of the spatial autoregressive model for the case when considered regions are split into two different groups, which have a mutual influence on each other. The weighing matrix in this model is split into four parts and four spatial coefficients are...

In this paper we analyse the demand for the foreign workforce in Russian regions. We use the Russian Ministry of Labour (Rostrud) data on migrant applications and the dataset on Russian firms provided by the Bureau van Dijk. We show features of the demanded migrant labour and also find that the...
