Russian budget structure efficiency: Empirical study

This paper investigates the economic efficiency of Russian public expenditures in 2002–2016 by estimation of their multiplicative impact on the GDP level and economic growth. We use the empirical methodology based on Corsetti et al. (2012). We estimate a number of fiscal multipliers: on national security, law-enforcement activity, national defense, education, health care and sport and road infrastructure. For assessing the influence of budget structure on long-term economic growth rates, we estimate the SVAR model in which GDP growth is a structural variable. The research shows a positive influence of budgetary resources redistribution from non-productive government expenditures to productive ones on economic development

Biodiversity of Floodplain Soils in the European North‐East of Russia

River floodplains are unique nature landscapes. In contrast to zonal communities on watersheds, soil biota of river floodplains is studied in less degree. The research was conducted in the floodplain forests in the European North‐East of Russia and showed high diversity of soil biota in alluvial forest soils. Floodplain forest soils are inhabited by 70 species of micromycetes, 53 genera of Nematoda, 60 species of Collembola, and 110 species of large invertebrates. Alluvial meadow soils with stable moisture and temperature conditions are characterised by high species diversity of micromycetes, nematodes and large invertebrates. Collembola prefer alluvial soddy soils. Soil microorganisms, meso‐ and macro‐fauna can essentially increase taxonomic diversity and number in alluvial meadow‐boggy soils at warming autumn

Factors of global inflation in 2021–2022

The paper examines the factors of global inflation acceleration in 2021–2022. We consider primarily the developed economies, where rates of inflation over the last two years have exceeded multi-year highs and have significantly exceeded target levels. We find that the cause of accelerating inflation was an imbalance between aggregate demand, which started to increase rapidly in the second half of 2020 as economies began to adapt to the circumstances of the pandemic, and aggregate supply, which encountered persistent constraints associated with interruptions in global supply chains. Significant support for demand was provided by fiscal stimulus that was unprecedented in scale and was accompanied by policy interest rates reaching extremely low levels, and by active injections of liquidity by central banks. The willingness of governments to implement ultra-expansionary monetary and fiscal policies can to a considerable degree be attributed to the fact that during the previous decade large budget deficits, zero interest rates, and programs of quantitative easing had not resulted in macroeconomic destabilization. We examine the view of many central banks that the inflationary wave would not be long-lasting, which was a crucial reason for delaying the interest rates increase. We consider the conditions in which the leading economies might fall into the stagflation trap

Cohesive strength of nanocrystalline ZnO:Ga thin films deposited at room temperature

In this study, transparent conducting nanocrystalline ZnO:Ga (GZO) films were deposited by dc magnetron sputtering at room temperature on polymers (and glass for comparison). Electrical resistivities of 8.8 × 10-4 and 2.2 × 10-3 Ω cm were obtained for films deposited on glass and polymers, respectively. The crack onset strain (COS) and the cohesive strength of the coatings were investigated by means of tensile testing. The COS is similar for different GZO coatings and occurs for nominal strains approx. 1%. The cohesive strength of coatings, which was evaluated from the initial part of the crack density evolution, was found to be between 1.3 and 1.4 GPa. For these calculations, a Young's modulus of 112 GPa was used, evaluated by nanoindentation

Fiscal maneuver and restructuring of the Russian economy

The paper discusses fiscal policy parameters through 2024. The suggested way to ensure long-term fiscal stability is stabilizing both the general government revenues and expenditures as percentages of GDP at levels differing by the public debt service payments and then applying a new version of the fiscal rule. The redistribution of fiscal spending from unproductive to productive areas (primarily investment in human and physical capital) is considered to boost economic growth. The possible use of additional spending on education, public health, and transport systems is presented, as is the optimization of expenditures in nonproductive areas

A new growth model for the Russian economy1

The problems underlying the current slowdown of the Russian economy are of a persistent nature and cannot be resolved with simple measures such as a softer monetary or fiscal policy. The fundamen- tal reason for these problems is the weak market environment dominated by public and quasi-public companies. A new growth model should be based upon strong incentive for the business, as well as the government regulation system, to improve efficiency. This article defines the main steps to be taken in building such a model

The Analysis of the Influence of Rock Massif Water Saturation on the Mine Workings Anchoring Design Parameters

Here in the study results of the sedimentary rocks water saturation effect on the main parameters of anchoring of mine workings: resistance, density and installation step of the support. A series of tests of rock samples with different intervals of their water saturation has been produced. It has been established that water saturation leads to a significant change in the strength properties of sedimentary rocks, depending on their petrographic composition and the period of exposure to moisture. The relation between the degree of water saturation and a decrease in the uniaxial compression strength, between the strength of a dry sample and its tendency to decrease in strength properties under the influence of moisture, between the period of exposure to moisture and decrease in strength properties has been established. The results of the study will allow to more accurately classify the rocks of the roof according to the factors of collapse and stability, which has a significant impact on the calculation of the anchoring parameters of mine workings in water-saturated zones

Abstract In this study, transparent conducting nanocrystalline ZnO:Ga (GZO) films were deposited by dc magnetron sputtering at room temperature on polymers (and glass for comparison). Electrical resistivities of 8.8 &#215; 10-4 and 2.2 &#215; 10-3 &#937; cm were obtained for films deposited on glass and polymers, respectively. The crack onset strain (COS) and the cohesive strength of the coatings were investigated by means of tensile testing. The COS is similar for different GZO coatings and occurs for nominal strains approx. 1%. The cohesive strength of coatings, which was evaluated from the initial part of the crack density evolution, was found to be between 1.3 and 1.4 GPa. For these calculations, a Young's modulus of 112 GPa was used, evaluated by nanoindentation.</p
