State-business relations and improvement of corporate governance in Russia
In this paper, we analyze the influence of the state on the improvement of corporate governance in Russia of the early 2000s. Taking into account the low quality of market institutions in the 1990s (i.e., the market failure phenomenon), we assume that state intervention as the âsecond bestâ institution had a positive impact in this case. Using a dataset of 822 joint-stock companies, we tested this hypothesis in two types of corporate models â state-owned or mixed firms and âpolitically connectedâ firms. The first model confirmed a strong positive influence of state ownership on the corporate governance in Russia in 2001-2004. The estimation results of this model are statistically robust in different specifications. We connect this result with attempts of the Russian government to use standard mechanisms and procedures of corporate governance to defend its property rights in its relations with state-owned and mixed enterprises.corporate governance; market institutions; state-owned companies; Russia
State-business relations in Russia in the 2000s: From the capture model to a variety of exchange models?
Using data from a 2009 survey of 957 manufacturing enterprises, this paper examines relations between the state and business as well as priority differences in the distribution of governmental support by federal, regional and local authorities. Regression analysis reveals that a âmodel of exchangeâ is the predominant pattern as opposed to âstate captureâ (in the case of big firms) or âgrabbing handâ (in the case of SMEs), both of which were typical of the 1990s. However, there are some differences in priorities at different levels of government. The federal government in 2007-2008 provided more support to state-owned and mixed enterprises providing stable employment, while regional authorities more often supported firms that were pursuing modernization. These trends could pave the way for a shift in governmental policy at the regional level from âstate captureâ/âgrabbing handâ to the Chinese-style âhelping handâ model.state capture; state-business relations; Russia
Diverse correlation structures in gene expression data and their utility in improving statistical inference
It is well known that correlations in microarray data represent a serious
nuisance deteriorating the performance of gene selection procedures. This paper
is intended to demonstrate that the correlation structure of microarray data
provides a rich source of useful information. We discuss distinct correlation
substructures revealed in microarray gene expression data by an appropriate
ordering of genes. These substructures include stochastic proportionality of
expression signals in a large percentage of all gene pairs, negative
correlations hidden in ordered gene triples, and a long sequence of weakly
dependent random variables associated with ordered pairs of genes. The reported
striking regularities are of general biological interest and they also have
far-reaching implications for theory and practice of statistical methods of
microarray data analysis. We illustrate the latter point with a method for
testing differential expression of nonoverlapping gene pairs. While designed
for testing a different null hypothesis, this method provides an order of
magnitude more accurate control of type 1 error rate compared to conventional
methods of individual gene expression profiling. In addition, this method is
robust to the technical noise. Quantitative inference of the correlation
structure has the potential to extend the analysis of microarray data far
beyond currently practiced methods.Comment: Published in at http://dx.doi.org/10.1214/07-AOAS120 the Annals of

Relative frequencies in multitype branching processes
This paper considers the relative frequencies of distinct types of
individuals in multitype branching processes. We prove that the frequencies are
asymptotically multivariate normal when the initial number of ancestors is
large and the time of observation is fixed. The result is valid for any
branching process with a finite number of types; the only assumption required
is that of independent individual evolutions. The problem under consideration
is motivated by applications in the area of cell biology. Specifically, the
reported limiting results are of advantage in cell kinetics studies where the
relative frequencies but not the absolute cell counts are accessible to
measurement. Relevant statistical applications are discussed in the context of
asymptotic maximum likelihood inference for multitype branching processes.Comment: Published in at http://dx.doi.org/10.1214/08-AAP539 the Annals of

Interaction of interest groups and their impact on economic reform in contemporary Russia
In seinem Aufsatz befasst sich der Autor mit der Frage, wer die von Präsident Putin angestrebten bzw. versprochenen Reformen in Russland unterstĂźtzt und voranbringt. Die thematische Auseinandersetzung gliedert sich in zwei Abschnitte: Das erste Kapitel vermittelt einen Ăberblick Ăźber den derzeitigen Forschungsstand. Dabei werden die bislang offenen Aspekte hervorgehoben und jene Trends betrachtet, die noch nicht ausreichend erklärt sind. Dazu zählen die ErĂśrterung (1) der Gewinner und Verlierer, (2) die Transformation der wirtschaftlichen und politischen Eliten und (3) die Entwicklung nach der Wirtschaftskrise Ende der 1990er Jahre. Das zweite Kapitel diskutiert die Entwicklung der Interessen einflussreicher sozialer Gruppen in der Post-Reform-Periode. Zudem wird der positive Einfluss der Finanzkrise von 1998 auf die Motivation wirtschaftlicher Kompetenzträger aufgezeigt und erklärt, warum die SchlĂźsselpersonen anschlieĂend ihre Entwicklungs- bzw. Expansionsanreize verlieren. In einer Schlussbetrachtung präsentiert der Autor jene Gruppen, die zu einer UnterstĂźtzung der politischen Reformen unter den derzeitigen Bedingungen fähig sind, indem die Implementierung wettbewerbsfähiger Institutionen und Mechanismen in die Ăśkonomische und politische Landschaft Russlands angestrebt wird.

Russia's Economy: Between a Crash and a Hard Landing
Based on macro-level data, most analysts forecasting Russia's economic development following the introduction of new large-scale sanctions expect a 10-12% drop in GDP, 20-25% inflation, and an increase in unemployment from 4.4% to 7-8% by the end of this year. This article argues that in the context of a severe economic shock, micro-data and comparison with similar cases offer a better guide to future developments than macro-data. They point to a much sharper decline in economic activity than is currently being forecasted
Fighting the Pandemic and Fighting Sanctions: Can the Russian Economy Now Benefit from Its Experience with Anti-Crisis Measures?
Faced with tough international sanctions in reaction to its war against Ukraine, the Russian government has resorted to measures developed during the COVID-19 pandemic in order to stabilize the economy. This short analysis discusses the rationale behind this approach and demonstrates its limits
A C++ Program for the CramĂŠr-Von Mises Two-Sample Test
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 CramĂĂŠr-von Mises test statistic under the null hypothesis that the two samples are drawn from the same continuous distribution. The program makes it possible to handle substantially larger sample sizes than earlier proposed computational tools. The C++ source code for the program is published with this paper, and an R package is under development.
Black cash tax evasion in Russia: Its forms, incentives and consequences at firm level
This paper discusses Russiaâs "black cash" economy. Using interviews and survey data, we examine the mechanics of several distinctly Russian tax evasion schemes and attempt a rough estimate of the scale and dynamics involved in tax evasion based on black cash. Entrepreneursâ opinions are also used to get an idea of the incentives and costs of black cash tax evasion. We next describe the apparent economic consequences of black cash tax evasion and formulate general formal conditions for successful evasion at firm level. Finally, we recommend several policy measures to reduce the incentives to such behaviour and discuss questions for future research.tax evasion; informal business activity; black cash; Russia
