Суммарная масса образующегося электронного лома в России в настоящее время приближается к 1,5 млн. тонн ежегодно, перерабатывается из них около 5-7 %. Это создает предпосылки для создания в России крупномасштабного производства вторичных металлов для создания новой отрасли металлургической промышленности. Целью магистерской диссертации является разработка теоретико-методических основ к оценке эффективности и выявления тенденций переработки электронных отходов и лома. В качестве источников использовалась учебно-методическая и научно-исследовательская литература, результаты эмпирических исследований автора и данные предприятий. В магистерской диссертации был разработан методический подход к выбору направления переработки электронных отходов и лома, соотнесенный с тенденциями, включающий систему показателей для выбора способа и результаты их экономической оценки, алгоритм принятия решения о способе переработки, что позволит на основании полученных результатов выбрать приоритетные направления для инвестирования. / The total mass of generated electronic scrap in Russia is currently approaching 1.5 million tons annually, of which about 5-7% is processed. This creates the preconditions for the creation in Russia of a large-scale production of secondary metals for the creation of a new branch of the metallurgical industry. The purpose of the master thesis is to develop theoretical and methodological foundations for evaluating the effectiveness and identifying trends in the processing of electronic waste and scrap. The sources used were educational, methodological, and research literature, the results of the author's empirical research, and enterprise data. The master thesis developed a methodological approach to choosing the direction of processing electronic waste and scrap, correlated with trends, including a system of indicators for choosing the method and the results of their economic assessment, an algorithm for deciding on the method of processing, which will allow you to choose priority areas for investment based on the results obtained.

In this paper, an attempt has been made to examine the evolution of corporate leverage of companies listed on the Johannesburg Stock Exchange (JSE) from 1994 to 2016. Analysis of the data set is organized around a sample of 126 listed companies across twelve sub-sector industries, namely, Banks, Financial Services, Life Insurance, Fixed Line Telecommunications, Nonlife Insurance, Health Care Equipment and Services, Pharmaceuticals and Biotechnology, Media, Technology Hardware and Equipment, Software and Computer Services, Electronic and Electrical Equipment and Support Services. 621 delisted companies were also briefly analysed to eliminate survivorship bias. Results of multiple regressions using two primary leverage measures and six commonly used determinants of capital structure were varied. Tangibility and growth were negatively related to debt while cost of debt was positively related to debt. Firm size, profitability and corporate tax rate yielded a varied relationship with corporate leverage. Only the growth capital structure determinant showed statistical significance. The overall findings indicate a rise in corporate leverage that coincides in tandem with major local and international economic events.
