摘要

这项研究偏离了现有的研究,考察了影子经济(SE)对环境污染的影响,以及制度指标在1992年至2015年间调节西非影响中所起的作用。具体而言,该研究采用了三个制度指标(腐败控制[COR]、法律与秩序[law]和官僚素质[BUQ])来调节效果,并确定其阈值。SE是使用多指标多原因(MIMIC)来测量的,而环境污染是用人均二氧化碳(CO2)来表示的。采用两步系统广义矩量法(GMM)得出研究结论。研究结果表明,SE、COR和LAW对环境污染有显著影响,而BUQ虽然不显著,但可以减少该地区的环境污染。此外,SE与所有制度指标的互动效应表明,在SE存在的情况下,强制度指标通过减少环境污染来减轻环境污染。在0–6的普通量表上,降低SE和减轻环境污染的制度指标的阈值分别为COR和LAW的3.8和3.7,而在0–4的普通尺度上,BUQ为2.8。尽管如此,该区域大多数国家的运作低于该区域机构指标的门槛水平。结果对环境污染的不同指标都是稳健的。讨论了这项研究的意义。

Shadow Economy and Environmental Pollution in West African Countries: The Role of Institutions
This study deviates from extant studies by examining the effect of shadow economy (SE) on environmental pollution, and the role institutional indicators play in moderating the effect in West Africa between 1992 and 2015. Specifically, the study employed three institutional indicators (corruption control [COR], law and order [LAW], and bureaucratic quality [BUQ]) to mediate the effect and also determine its threshold values. SE is measured using Multiple Indicators Multiple Causes (MIMIC) while environmental pollution is proxy by carbon dioxide (CO2) per capita. Two step system Generalized Method of Moments (GMM) is used to drive out the conclusions of the study. The findings reveal that SE, COR and LAW contribute significantly to environmental pollution, while BUQ though not significant, reduces environmental pollution in the region. Further, the interactive effect of SE with all the institutional indicators shows that strong institutional indicators abate environmental pollution through reduction in the presence of SE. The threshold value of institutional indicators, which reduces SE and abates environmental pollution, are 3.8 and 3.7 for COR, and LAW, respectively, on an ordinary scale of 0–6, while 2.8 for BUQ on an ordinary scale of 0–4. Nevertheless, most of the countries in the region operate below the threshold level of institutional indicators in the region. The results are robust to different proxies of environmental pollution. The implications of the study are discussed.

期刊介绍: Global Journal of Emerging Market Economies is a peer-reviewed journal. The aim of the journal is to provide an international platform for knowledge sharing, discussion and networking on the various aspects related to emerging market economies through publications of original research. It aims to make available basic reference material for policy-makers, business executives and researchers interested in issues of fundamental importance to the economic prospects and performance of emerging market economies. The topics for discussion are related to the following general categories: D. Microeconomics E. Macroeconomics and Monetary Economics F. International Economics G. Financial Economics H. Public Economics I. Health, Education, and Welfare J. Labor and Demographic Economics L. Industrial Organization O. Economic Development, Innovation, Technological Change, and Growth Q. Agricultural and Natural Resource Economics • Environmental and Ecological Economics R. Urban, Rural, Regional, Real Estate, and Transportation Economics Additionally, the journal would be most interested to publish topics related to Global Financial Crisis and the Impact on Emerging Market Economies Economic Development and Inclusive Growth Climate Change and Energy Infrastructure Development and Public Private Partnerships Capital Flows to and from Emerging Market Economies Regional Cooperation Trade and Investment and Development of National and Regional Financial Markets The Belt and Road Initiative.
