The article contains a review of the contemporary research in the field of economics of happiness. Economics of happiness deals with correlation between the subjective notion of well-being and happiness with ones life (happiness level) and economic indicators. The author considers the correlation of economic and noneconomic factors. The last ones —  such as education and health — also affect the level of happiness. The author dwells upon the following questions: research methodology in economics of happiness, correlation between subjective notion of well-being and happiness with ones life and economic performance on micro- and macrolevels.

Variants of the intensification of the solvent dewaxing process, which increase the yield of base oils, are described. One of the promising ways to improve the technical and economic indicators of the dewaxing process is the use of modifying additives. The work shows that the introduction of a polymer additive requires a decrease in the filtration rate and, accordingly, an increase in the performance of the dewaxing unit. This results in a petrolatum with a reduced oil content, which is a qualifying factor for the production of high-melting ceresins, protective-wax components, and lubricants for various purposes.

The study was targeted at developing a methodology for constructing a macroeconomic performance index at a provincial level for the first time in Vietnam based on 4 groups of measurements: (i) Economic indicators; (ii) oriented economic indicators; (iii) socio-economic indicators; and (iv) economic - social – institutional indicators. Applying the methodology to the 2011 - 2015 empirical data of all provinces in Vietnam, the research shows that the socio-economic development strategy implemented by those provinces did not provide balanced outcomes between growth and social objectives, sustainability and inclusiveness. Many provinces focused on economic growth at the cost of structural change, equality and institutional transformation. In contrast, many provinces were successful in improving equality but not growth. Those facts threaten the long-term development objectives of the provinces.

The article is devoted to contemporary overview of development of a number of display technologies, which have been applied or may be applied for creation of new prospective light engineering solutions. The emphasis is on OLED-based technologies and liquid crystalsbased technologies. Examples of their application in automotive industry and architecture are given with consideration of various economic indicators and hygienic and usability limitations.

Subject. We investigate trends in the development of the largest steel companies in the Russian Federation. Objectives. The aim of the study is to conduct an industry-wide analysis of the production and economic activities of the largest domestic enterprises operating in the iron and steel industry. Methods. The study employs methods of comparative and system analysis, graphical and statistical methods for data processing. Results. We present the analysis of main production and economic indicators of the leading steel producers of the Russian Federation, i.e. NLMK, Severstal, MMK, and EVRAZ. The paper reveals their current status and key development trends. Conclusions. The largest Russian steel companies face serious challenges in both the domestic and foreign market. Competitive interactions in the domestic market as to the sale price of rolled metal and the share of presence are particularly sensitive. The threat of reduced supplies to export markets is also significant for Russian steel producers. It may entail insufficient utilization of capacities and potential loss of added value. The companies mainly export semi–finished goods and hot-rolled flat products, i.e. low-added value products. Products with high added value are usually delivered to the domestic market.

The paper presents the results of long-term research on the oil productivity and chemical composition of soybean oil of the Northern ecotype varieties in the Central Non-Black Earth Region. The authors consider its possible use for biodiesel production. Experiments on growing soybeans were carried out on the experimental fi eld of Russian State Agrarian University –Moscow Timiryazev Agricultural Academy (2008-2019) on recognized ultra-early ripening varieties of the Northern ecotype Mageva, Svetlaya, Okskaya (ripeness group 000). Tests were set and the research results were analyzed using standard approved methods. It has been shown that in conditions of high latitudes (57°N), limited thermal resources of the Non-Chernozem zone of Russia (the sum of active temperatures of the growing season not exceeding 2000°С), the yield and productivity of soybeans depend on the variety and moisture supply. Over the years, the average yield of soybeans amounted to 1.94 … 2.62 t/ha, oil productivity – 388 … 544 kg/ha, oil content – 19…20%, the content of oleic and linoleic fatty acids in oil – 60%, and their output from seeds harvested – 300 kg/ha. It has been established that as soybean oil and diesel fuel have similar properties,they can be mixed by conventional methods in any proportions and form stable blends that can be stored for a long time. Experimental studies on the use of soybean oil for biodiesel production were carried out on a D-245 diesel engine (4 ChN11/12.5). The concentrations of toxic components (CO, CHx, and NOx) in the diesel exhaust gases were determined using the SAE-7532 gas analyzer. The smoke content of the exhaust gases was measured with an MK-3 Hartridge opacimeter. It has been experimentally established that the transfer of a diesel engine from diesel fuel to a blend of 80% diesel fuel and 20% lubrication oil leads to a change in the integral emissions per test cycle: nitrogen oxides in 0.81 times, carbon monoxide in 0.89 times and unburned hydrocarbons in 0.91 times, i.e. when biodiesel as used as a motor fuel in a serial diesel engine, emissions of all gaseous toxic components are reduced. The study has confi rmed the expediency of using soybeans of the Northern ecotype for biofuel production.
