    Lack of investments in fixed assets which stimulate economic growth is one of the problems of the modern Russian economy. According to the main hypothesis of the research, that corporate profit taxation decreases companies’ investment level, we aimed to assess the level of impact of profit taxation on investments in fixed assets. To test the hypothesis, we estimate the empirical investment equation, using the indicator of tax burden as one of the factors affecting investment. The theoretical basis of the research is the neoclassical cash-flow model. The marginal effective tax rate (METR) was used as an indicator of the tax burden. The empirical equation was estimated using a random effects model on the panel microdata, which includes financial statistics of 4,000 Russian companies for the period 2014–2018. The sample companies represent 78 regions of Russia and about 50 types of economic activity. We assumed heterogeneous effect of profit taxation and estimated the model separately for each of the three groups of companies differing in the degree of financial constraints. According to the results obtained, for the entire sample, for the entire period under review, we observe a negative impact of the marginal effective rate on the level of investment, significant at the 1% level. In aggregate, if the marginal effective tax rate falls by 1 percentage point, the investment level will increase by 0.05 percentage points. We obtained the following main results: profit taxation has a significant negative effect on the level of investment for companies that are not financially constrained, and the effect is not observed for financially constrained companies; younger companies are more sensitive to changes in profit taxation. However, general sensitivity of investment to profit taxation is quite modest.For citationBelev S.G., Matveev E.O., Moguchev N.S.

Согласно неоклассической теории инвестиций, низкая инвестиционная активность российских компаний может объясняться высокой налоговой нагрузкой. В данной работе оценивается масштаб влияния налогообложения прибыли на инвестиции в основные фонды. Основная гипотеза заключается в том, что налогообложение прибыли снижает уровень инвестиций. Теоретической основой исследования является неоклассическая модель потоков денежных средств. В качестве индикатора налоговой нагрузки для эмпирической оценки инвестиционной функции использовалась предельная эффективная ставка налога (METR), которая представляет собой ставку налога на предельную единицу прибыли и позволяет оценить влияние налогообложения прибыли на интенсивное развитие компании, в том числе на наращивание инвестиционной активности. Эмпирическое уравнение оценивалось с помощью модели случайных эффектов на панельных микроданных по финансовым показателям 4000 российских компаний за период 2014-2018 гг. В предположении о неоднородности эффекта налогообложения прибыли, модель оценивалась отдельно для трех групп компаний, различающихся степенью финансовых ограничений. Получены следующие основные результаты: налогообложение прибыли оказывает значимое отрицательное влияние на уровень инвестиций компаний, не ограниченных в финансовых ресурсах; инвестиции финансово ограниченных компаний оказываются не чувствительны к изменению налоговой нагрузки; более молодые компании чувствительнее к изменениям в налогообложении прибыли. Однако общая чувствительность инвестиций к налогообложению прибыли достаточно умеренная.Для цитированияBelev S.G., Matveev E.O., Moguchev N.S.

    Determination of the optimal working fluid for the turbine recovering combustion engine exhaust gases heat

    Microsteam turbine implementation for combustion engine exhaust gases heat recovery and subsequent acquisition of additional power is being investigated in many developed countries of the world. The results of such studies have already found application in some trucks. But this type of turbines is very weak in the Russian market. Turbine installation behind the combustion engine works under conditions of low volumetric flow of work fluid. This leads to a decrease in the height of the blade and vane wheels flow passage and an increase of the relative values of the gaps in the seals which are the reasons for the growth of the working fluid leakages. High degree of pressure reduction when selecting single-stage turbine leads to a supersonic velocity in the flow passage and an increase of the losses due to powerful shock waves. The efficiency of the turbine installation under these operating conditions is low and requires additional investigations. In this work, the working fluids which can give the greatest efficiency of the turbine installation were investigated. It was shown that not only thermodynamic but also hazardous and economic parameters must be taken into consideration. Working fluid with the high thermodynamic efficiency was compared with the one that profitable from economic point of view. The most appropriate substance was chosen and implemented in the microsteam turbine. The turbine stage which allows increasing economy and ecological compatibility of the combustion engine was developed and optimized by analytical methods

    Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

    Get PDF
    A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

    Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

    Get PDF
    Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe

    Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

    We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe

    Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

    The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe

    Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

    This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat
