Abstract

Purpose

The development of green economy is of academic and policy importance to governments and policymakers worldwide. In the light of the necessity of renewable energy to sustain green economic growth, this study aims to examine the relationship between renewable energy consumption and green economic growth, controlling for the impact of trade openness for Organization for Economic Co-operation and Development countries over the period 1990-2015, within a multivariate panel data framework.

Design/methodology/approach

To investigate the long-run relationship between variables, panel cointegration tests are performed. Panel Granger causality based on vector error correction models is adopted to understand the short- and long-run dynamics of the data. Furthermore, ordinary least square (OLS), dynamic OLS and fully modified OLS methods are used to confirm the long-run elasticity of green growth for renewable energy consumption and trade openness. Moreover, system generalized method of moment is applied to eliminate serial correlation, heteroscedasticity and endogeneity problems. The authors used the panel Granger causality test developed by Dumitrescu and Hurlin (2012) to infer the directionality of the causal relationship, allowing for both the cross-sectional dependence and heterogeneity.

Findings

The results suggest that renewable energy consumption and trade openness exert positive effects on green economic growth. The results of long-run estimates of green economic growth reveal that the long-run elasticity of green economic growth for trade openness is much greater than for renewable energy consumption. The estimated results of the Dumitrescu and Hurlin (2012) test reveal bidirectional causality between green economic growth and renewable energy consumption, providing support for the feedback hypothesis.

Practical implications

This paper provides strong evidence of the contribution of renewable energy consumption on green economy for a wide range of countries. Despite the costs of establishing renewable energy facilities, it is evident that these facilities contribute to the green growth of an economy. Governments and public authorities should promote the consumption of renewable energy and should have a support policy to promote an active renewable energy market. Furthermore, the regulators must constitute an efficient regulatory framework to favor the renewable energy consumption.

Social implications

Many countries focus on increasing their GDP without taking the environmental impacts of the growth process into account. This paper shows that renewable energy consumption points to the fact that countries can still increase their economic growth with minimal damage to environment. Despite the costs of adopting renewable energy technologies, there is still room for economic growth.

Originality/value

This paper provides evidence on the contribution of renewable energy consumption on green economic growth for a wide range of countries. The paper focuses on the impact of renewable energy on economic growth by taking environmental degradation into consideration on a wide scale of countries.

Abstract

Purpose

With a substantial return and volatility characteristic of Bitcoin, which may be seen as a new category of investment assets, better understanding of the nature of return and volatility spillover can help investors and regulators in achieving the potential goal from portfolio diversification. The paper aims to discuss these issues.

Design/methodology/approach

This paper explores the return and volatility transmission between the Bitcoin, as the largest cryptocurrency, and other traditional asset classes, namely stock, bond and currencies from the standpoint of Turkey over the period July, 2010–June, 2018 using the newly developed multivariate econometric technique, VAR–GARCH, in mean framework with the BEKK representation.

Findings

The empirical results reveal the existence of the positive unilateral return spillovers from the bond market to Bitcoin market. Regarding the results of shock and volatility spillovers, there exists strong evidence of bidirectional cross-market shock and volatility spillover effects between Bitcoin and all other financial asset classes, except US Dollar exchange rate.

Originality/value

The important extention is the adoption of a newly developed multivariate econometric technique, VAR–GARCH, in mean framework with the BEKK representation, proposed by Engle and Kroner (1995), which is employed for the first time specifically to examine the extent of integration in terms of volatility and return between Bitcoin and key asset classes. Second, Bitcoin has experienced a rapid growth since around a decade and a number of investors are showing interest in its potential as an integrative part of portfolio diversification. The information provided by empirical results gives empirical bases from which to address topics concerning hedging purposes and optimal portfolio allocation. It is also increasingly important to analyze the current behavior of Bitcoin in relation to other assets to provide policy makers and regulatory bodies with guidance on the role of the Bitcoin as an investment asset in Turkey. Thus, this is the first serious attempt at exploring the potential for Bitcoin to offer diversification opportunities in the context of Turkey.

Abstract

Purpose

This study investigates possible shock transmission and volatility spillover effects among the exchange rate changes and international portfolio flows for United States vis-à-vis two fast-growing emerging country groups: the BRICS (Brazil, Russia, India, China and South Africa) and MINT (Mexico, Indonesia, Nigeria and Turkey).

Design/methodology/approach

Applying VAR-BEKK-GARCH model, the evidence indicates that exchange rate fluctuations have a negative impact on net equity flows in Brazil, Russia, India and Turkey; thus, supporting the view that exchange rate uncertainty is an important driver of equity home bias.

Findings

As for the comparison of the pre- and post-crisis period, the findings support the evidence that the post-crisis period witnessed a greater number of cases of significant shock and volatility spillovers among exchange rate uncertainty and portfolio flows.

Originality/value

Overall, the empirical results provide fresh insights and policy implications for domestic and international investors through investment activities, and for policymakers through maintaining economic and financial stability.

Abstract

Throughout history, the actions of human beings have been analysed based on ethics. In every aspect of human life, ethics is an essential element, and business life is no exception. Business ethics, and marketing ethics in particular, has been a subject of interest in both the academic and business world. Apart from doing what is perceived as correct, acting in a socially responsible and sustainable manner becomes compulsory, as the changes in ecological and social environment necessitate this. There have been warning signs from nature such as environmental disasters and climate change, and it is no longer possible for for firms or individuals to continue with previous behaviours. Acting as if the world’s resources are limitless has caused damage to the environment. A new way of thinking and behaving is needed. The awareness and involvement levels about sustainability and social responsibility are not the same everywhere in the world. Culture has significant impact on perception of social issues such as social responsibility and sustainability. Turkey, as a developing country with its own cultural dynamics, differs from developed Western countries which makes analysing consumer ethics, corporate social responsibility and sustainable consumption in Turkey worthwhile.

In this chapter, concepts of business ethics, marketing ethics, consumer ethics, sustainable consumption and corporate social responsibility are discussed with specific examples from Turkey.
