Introduction. The article provides an algorithm for assessing the damage from a fire on the territory of gas compressor stations using a multifactor model of scenarios for the development of a fire. The causes of fires at the facilities of gas compressor stations are analyzed on the basis of statistical data. The established algorithm was verified by calculating the damage from fires, and the most dangerous causes of fires on the territory of gas compressor stations were established by the values of the frequency of emergency ruptures. The purpose of the study is establishing an algorithm for assessing fire damage based on a multivariate analysis of scenarios for the development of fires at gas compressor stations. Research methods. To obtain the results, general scientific and special methods of scientific knowledge were used. These are analysis, generalization, economic analysis, analysis of empirical data, which were based on the general provisions of the theory of analysis and systems analysis. The results of the study. A multivariate analysis of scenarios for the development of fires on the territory of gas compressor stations is carried out. An algorithm is found for assessing fire damage based on a multivariate analysis of scenarios for the development of fires at gas compressor stations. Conclusion. Using the results of the analysis of scenarios of fire development on the territory of gas compressor stations and calculations of indicators of economic damage from fires at these facilities, it is possible to draw up an algorithm for assessing fire damage on the territory of gas compressor stations. Key words: efficiency, analysis, statistics, fire, gas compressor stations, state fire control authorities, damage calculation.

This paper analyzes how the risk-adjusted returns of green funds compare to those of conventional funds, between the years 2005 and 2020 for the European Union countries. Additionally, we tested how the performance of green funds correlates to the business cycle, subdividing their performance through expansionary and recessionary times. The findings are summarized as follows: our regression results demonstrated green and conventional funds exhibiting negative abnormal adjusted-returns against the developed world market benchmark for the single-factor and multifactor models. For the European market benchmark, we found environmental mutual funds presenting a positive performance for both models and conventional funds displaying negative results for the single-factor model and positive results for the multifactor model. The factor loadings for green funds indicated a negative load on momentum, book-to-market (HML) and size (SMB) factors, revealing a higher exposure to big and value companies. Subsampling per business cycle exhibited green mutual funds providing higher risk-adjusted returns to investors during crisis periods and mixed results for the non-crisis periods.

The influence of a specific social development situation on the operational and motivational components of social cognition in orphan adolescents investigated. The theoretical basis of the study was the provisions of the "social situation of development" L.S. Vygotsky, theories of attachment by J. Bowlby, the multifactor model of social cognition A.B. Kholmogorova, O.V. Rychkova. 68 orphans aged from 10 to 17 years old living in the orphanage examined. It shown that orphaned teenagers with an insecure type of attachment have more difficulty in understanding their own feelings, regardless of the length of their stay in the institution. Orphans living in institutions for more than 5 years have a higher level of social anxiety and distress during social interaction.

Introduction. Such variables as number of employees in marketing of organisation, value of marketing expenses, cost on innovation, the number of marketing staff, the share of marketing efforts which is undertaken in cooperation with the city council and different non-profit organizations, the marketing costs, the level of satisfaction of marketers, level of marketing potential, level of innovation potential are considered in this research. They are marketing factors that can affect the level of social impact of Ukrainian providers of urban public transport services. Purpose. The article aims to obtain the adequate econometric model which can demonstrate the relationship between marketing factors, innovation development and the non-economic effect of business entities which provide the urban public transport services. Method (methodology). The results of evaluation of social effect of Ukrainian providers of urban public transport services are evaluated on the basis of mathematical multifactor model. They are presented in the article. Results. The adequate econometric model has been worked out in this research. This model shows the relationship between controllable marketing factors and social effect has been presented in the article. We have determined the controllable marketing factors. They are number of employees and volunteers in marketing, the average monthly wage of employees in marketing, satisfaction of volunteers, total current assets of an organization, and the level of marketing potential. The model can be used to predict the level of social (ecological) impact of providers of urban public transport services in the Ukrainian society.

The current model of resource management mainly contributes to mass short-term consumption, which creates an unstable and extremely critical situation on the planet. Going beyond the traditional industrial model of Take-Make-Waste, the circular economy aims to reduce waste (and therefore minimize costs) and to redefine sustainable development. This entails a gradual separation of economic activity from the consumption of scarce resources and the removal of waste from the system. In order to foreground the principles of a circular economy in Ukraine, this study analyzes its benefits based on the relevant experience of the EU. The paper also presents the results of research and content analysis on the situation of waste management in Ukraine and compares the trends using key indicators. The core of the paper is developing a conceptual model of making and coordinating management decisions on the implementation of business projects in the context of a circular economy in Ukraine. A multifactor model (the Farrar–Glauber method was further developed) has been built by identification of the main factors, i.e., the volume of generated waste from economic activity per unit of GDP at constant prices, emissions of pollutants, and capital investments for the protection of the environment. Factor coefficients indicate how many units will change the resultant trait Y, measured in thousand tonnes, if one of them changes by 1 (each in units of measure). It means that if the volume of waste generated from economic activity per unit of GDP at constant 2011 purchasing power parity (PPP) prices decreases by 1 kg/$1000, waste management of I–IV classes will be reduced by 952,737 thousand tonnes. The approbated model can be used to analyze the situation with recycling in the EU countries, considering the amount of capital investment in environmental protection.

<p>In this paper, we propose analytical valuation formulae for three types of quanto floating range notes based on the cross-currency LIBOR market model. The dynamics of forward LIBOR rates is a multifactor model that incorporates both the domestic and foreign interest rate process and the exchange rate process in a cross-currency environment. The derived formulae are analytically tractable and easy to implement in practice. The model parameters can be extracted directly from market quantities. We show that the empirical results are more accurate and robust than the results ofMonte Carlosimulation.</p>
