This paper aims to explore the stock market returns-COVID-19 interdependence via wavelet coherence analysis. The sample comprises the top 15 affected countries by novel coronavirus outbreak, covering each continent over the period 1 January 2020 to 23 July 2020. Using daily stock index returns, COVID-19 new cases and new deaths, the empirical findings reveal that most of the stock market returns are in phase (cyclical effects) with pandemic variables, whereas a couple of stock index returns exhibit an out-of-phase behaviour (anti-cyclical effects).

This paper aimed to investigate the impact of water, waste, and energy consumption on firm performance for a sample of enterprises that belong to the S&P 500 Information Technology sector over the period of 2009–2020. The quantitative framework covered both accounting (e.g., return on assets—ROA; return on common equity—ROE; return on capital—ROC; return on invested capital—ROIC) and market-based measures of performance (e.g., price-to-book value—PB), alongside firm and corporate governance specific variables. By estimating multivariate panel data regression models, the empirical results provided support for a negative impact of total water use on PB but a positive effect on ROA. With reference to the total waste, the econometric outcomes revealed a negative influence on the entire selected performance measures, whereas total energy consumption did not reveal any statistically significant influence.

Small and medium-sized enterprises (SMEs) are crucial for local economic development, playing a noteworthy role in job creation, poverty alleviation and economic growth, but they encounter many funding barriers. The purpose of the current paper is to investigate the impact of investments and innovation on territorial economic growth, as measured by turnover, for Romanian active enterprises, especially SMEs, over the period 2009–2017. By estimating several log–log linear regressions, the quantitative outcomes provide support for a positive influence of investments on turnover. The association was confirmed both for all active enterprises at the national level, as well as for micro, small, middle-sized and big companies. As regards expenditures on innovation, a positive impact on turnover was acknowledged for all enterprises and particularly for big companies, but there was an absence of any statistically significant relation in the case of SMEs. The impact of firm size on turnover was positive for all active enterprises at the national level, along with active micro-units. Also, the estimation results show a positive impact of the number of active micro-units on territorial economic growth. The empirical findings are relevant to managers and policymakers in order to stimulate, encourage and offer support to SMEs’ development through their strategies.

This study aims to examine the link between foreign direct investment (FDI) inflows and economic growth, also considering several institutional quality variables, as well as sustainable development goals (SDGs) set in the 2030 Agenda for Sustainable Development. By estimating panel data regression models for a sample of 11 Central and Eastern European countries, from 2003 to 2016, the empirical outcomes provide support for a non-linear relationship between FDI and gross domestic product per capita. Regarding institutional quality, it is found that control of corruption, government effectiveness, regulatory quality, rule of law, and voice and accountability positively influence growth, while political stability and absence of violence/terrorism is not statistically significant. Moreover, SDGs such as poverty, income distribution, education, innovation, transport infrastructure, and information technology are noteworthy drivers of growth. The outcomes of panel fully modified and dynamic ordinary least squares partly confirm the findings. The panel vector error-correction model Granger causalities provide support for a short-run one-way causal association running from FDI to growth and a long-run two-way causal connection among FDI and growth. Furthermore, in the long run, unidirectional causal relationships running from each institutional quality indicator to economic growth and FDI are set out.

The present paper empirically examines the relation between corporate social responsibility (CSR) practices and company financial performance (CFP) for firms listed on the Bucharest Stock Exchange. Likewise, the paper analyzes the CSR policies adopted by the companies as CSR practices towards six types of stakeholders that influence the CFP. Using principal component analysis, we developed a CSR index and several specific indices for CSR practices. By estimating cross-sectional regression models, our study provides support for a positive link between CSR and CFP, when companies implement CSR policies regarding employees, environmental protection, and ethics as social practices. Further, empirical findings show that companies responsive to the CSR concept and those considering international standards and regulations for quality products and services in their business strategy enhance CFP.

The increased attention of companies’ managers towards the benefits of corporate social responsibility (CSR) has led many corporations to integrate CSR practices into their business strategy. Consequently, the literature has examined the relation between CSR and firm performance. Although CSR is adopted by companies on a voluntary basis, more heated discussions regarding the effects of CSR on company financial performance has lead various authors to different results. This chapter empirically analyzes the CSR effects on company financial performance in developing countries, especially Romania. As empirical method we employed univariate analysis to investigate whether the company financial performance of companies which implement CSR (considered experiment group) is higher than non-CSR companies (considered control group). T-test is used to find out if there is any statistically difference in mean company financial performance between ROA, ROE, ROS, PBV, PER, and EPS of experiment group and control group. The sample used included 68 companies listed on the Bucharest Stock Exchange (BSE) for the 2011 fiscal year. The empirical research reveals that there is not a significant difference in mean company financial performance between CSR companies and non-CSR companies.

This chapter describes the ways in which CSR practices can develop and strengthen company’s relation with their key stakeholders in order to create both social and financial value to the companies. Using companies CSR reports, current study identifies theoretically for the case of Romania the mechanisms and the important contingencies in whether the CSR practices are considered by stakeholders authentically and effective and if these practices persist in time. The importance of relation between company and stakeholders through CSR practices is due because of the long term success of the company as there are outside immediate profit maximization goals. We conclude from companies CSR reports and websites that in order to achieve long term financial performance, they (the companies) engage in specific CSR activities as social activities. Thus, companies select ‘the right’ social activities turning them into companies’ strategies addressed to specific types of stakeholders, namely to those are trying to strengthen their relation with.
