This article addresses Russia's barter economy. Using interview data, it examines the mechanics of barter settlements and classifies the main types of non-monetary transactions. The major reason for barter is lack of a competitive monetary system. In the 1990s barter represented a specific...

This paper analyzes the phenomenon of repeated procurements made by public sector customers from the same supplier. The previous surveys of “relational contracts” gave different explanations for the possible implications of such repeated procurements, but those surveys dealt mostly with...

This paper considers the consequences of public procurement reform in Russia in 2005-2006. We show that before the reform, manufacturing firms with government stakes, old firms and larger firms had advantages in access to government orders. In 2009 large firms retain their advantages in access...

As larger sets of high-throughput data in genomics and proteomics become more readily available, there is a growing need for fast algorithms designed to compute exact p values of distribution-free statistical tests. We present a program for computing the exact distribution of the two-sample...

One of the prevailing ideas in the literature on microarray data analysis is to pool the expression measures across genes and treat them as a sample drawn from some distribution. Several universal laws were proposed to analytically describe this distribution. This idea raises a number of...

This article is devoted to analysing the evolution of corporate governance mechanisms in Russia. Special attention is paid to the causes of dramatic discrepancies between the expected outputs of institutional reforms implemented by the Russian government with World Bank and IMF support and the...

Stochastic dependence between gene expression levels in microarray data is of critical importance for the methods of statistical inference that resort to pooling test statistics across genes. The empirical Bayes methodology in the nonparametric and parametric formulations, as well as closely...

Modern methods of microarray data analysis are biased towards selecting those genes that display the most pronounced differential expression. The magnitude of differential expression does not necessarily indicate biological significance and other criteria are needed to supplement the information...
