Ukraine’s recent elections revealed deep divisions between eastern regions, which favored central economic planning, and western
regions, which preferred more free market reforms. This study compares polyclinics in Ukraine to see if the inflexibility
of Soviet-style planned economies results in lower economic efficiency in eastern regions. Using data from two geopolitical
regions, Data Envelopment Analysis (DEA) scores for polyclinic efficiencies are modeled as a function of demographic and economic
determinants. Surprisingly, results indicate that polyclinics in western Ukraine are less efficient. Possible explanations,
including case mix intensity, responsiveness to local preferences, physician entrepreneurial behavior and a legacy of inequitable
funding, are discussed.

The study analyses technical efficiency and efficiency change of 193 community hospitals and polyclinics across Ukraine, for
the years 1997–2001. These facilities are a subset of the medical institutions in rural Ukraine; they are identical w.r.t.
their function in the health system and share the same departmental structure. The data comprise the number of beds in the
hospitals, the number of staff employed in the hospitals as well as the polyclinics connected to the hospitals, the number
of inpatient and outpatient admissions as well as the number of surgical procedures, lab tests, X-rays performed and the number
of deaths and deaths after surgery. Because of the known sensitivity of traditional nonparametric frontier estimators to outlier
observations, we employ an order-m estimator, a robust technique, to assess the efficiency of these health care providers as well as changes of their productivity
time. The efficiency scores are calculated with an output-oriented model; they are close to unity for hospitals whereas polyclinics
seem somewhat less efficient. The Malmquist-indices averaged over all observations are close to unity indicating that productivity
does not change over during our observation period. But, depending on the period and the region, substantial deviations from
unity can be observed.

We empirically test the dependence of the Russian stock market on the world stock market and world oil prices in the period 1997:10–2012:02. We also analyze countries that can be considered to be relatively similar to Russia, e.g., Poland, the Czech Republic, and South Africa. First, we apply a rolling regression to identify periods when oil prices or stock indices in the United States and Japan were important. Surprisingly, oil prices are not significant for the Russian stock market after 2006. Second, we employ a TGARCH-BEKK model to assess the degree of correlation between the markets in question, taking into account the global market stochastic trend. Correlation between markets increased between 2000 and 2012. 相似文献

The different segments of he Russian financial markets are studied in the paper. The market crashed on 17 August 1998. We consider the stable period of the market between May 1996 and October 1997. We study the structure of interactions between the GKO market, stock market, currency market, currency futures market, GKO futures market, interbank credit market. We study the relations between the world financial market and the Russian financial market. It was shown that, in the period under consideration, different segments of the Russian financial market became more integrated and the market as whole became more stable and more integrated in the international capital flows. 相似文献

The main result of the paper is the following characterization of the generalized arcsine density p γ (t) = t γ?1(1 ? t) γ?1/B(γ, γ) with ${t \in (0, 1)}$ and ${\gamma \in(0,\frac12) \cup (\frac12,1)}$ : a r.v. ξ supported on [0, 1] has the generalized arcsine density p γ (t) if and only if ${ {\mathbb E} |\xi- x|^{1-2 \gamma}}$ has the same value for almost all ${x \in (0,1)}$ . Moreover, the measure with density p γ (t) is a unique minimizer (in the space of all probability measures μ supported on (0, 1)) of the double expectation ${ (\gamma-\frac12 ) {\mathbb E} |\xi-\xi^{\prime}|^{1-2 \gamma}}$ , where ξ and ξ′ are independent random variables distributed according to the measure μ. These results extend recent results characterizing the standard arcsine density (the case ${\gamma=\frac12}$ ). 相似文献

Homeowners associations (HOAs) implement collective management in residential housing. We assess the performance of such associations in Russia by using the stochastic frontier technique. Cultural traits enabling tenants to make proper use of the HOA decision-making procedures are essential for resolving the collective action problem and ensure accountability of governing bodies and outside contractors. Such “technical civic competence” has a stronger impact on HOA performance than more conventional forms of social capital which rise in their significance when HOA governance breaks down and informal grassroots alternatives are mobilized instead. Massive and indiscriminate “supply-led” introduction of collective management in residential housing without matching cultural and institutional prerequisites could be counterproductive. Flexibility, freedom of choice, and market development are required to avert the failures of HOAs commonly observed in Russia. 相似文献

Motivations and Obstacles for Small Business Entrepreneurship in Russia: Fifteen Years in Transition
A longitudinal survey of small business entrepreneurs was conducted in Russia in two stages: in 1994 and in 2008. This study examined entrepreneurial climate and developments in Russia's small businesses with a focus on motivations and obstacles in starting up and operating businesses. It also aimed at analyzing entrepreneurs’ needs for training, consulting, and other types of assistance in a comparative context. Russia's climate for small and medium enterprises (SME) and entrepreneurship has improved, although it is still a work in progress. The 2008 survey indicated younger age, greater share of female entrepreneurs, and remaining small size of the firms. Though the level of SME entrepreneurial activities in Russia is still lower than in major developed economies, the gap is diminishing. Thise study found no significant differences between 1994 and 2008 in terms of entrepreneurial motivations and obstacles; several shifts and trends in motivations and obstacles were identified in their relative importance in SME dynamics. 相似文献
