ABSTRACT
Purpose: The stringency policy and economic support policy in response to and to address the coronavirus disease 2019 have become a significant concern since the end of 2019. The motivation that led to this study is that, the selection of the stringency policy and the economic support policy appear to have brought about the opposite effects of the environmental costs of carbon dioxide emissions. The study's objective is to examine the contradictory impacts of these stringency and economic support policies on carbon dioxide emissions. Design/methodology/approach: This study applies panel data for the top four countries responsible for carbon dioxide emission, namely China, the United States of America, India and Russia. A fully modified ordinary least squares estimator and dynamic ordinary least squares estimator are employed to determine the long-run parameters. Findings: The results indicate that the effect of reduced carbon dioxide emissions due to a one-unit increase in the stringency policy is greater than the effect of increased carbon dioxide emissions caused by a one-unit increase in the economic support policy. Hence, if the two policies are implemented simultaneously, a positive net effect on environmental costs will be gained. Research limitations/implications: The study investigates in a general scope, the impact these response policies have on the environment. Future researchers may enhance the research on environmental impact in different sectors due to the implementation of both policies to enrich the analytical perspective. Practical implications: The results have provided implications for policymakers to emphasize more on stringency-oriented policies while giving economic support to the low-income or unemployed households in order to reduce carbon dioxide emissions. Originality/value: Despite the foreseen effects of the stringency policy and economic support policy, there has hardly been any studies that have explored empirically the nexus between both policies with carbon dioxide emissions in one empirical model. Furthermore, the paper uses the high-frequency data in determining the contradictory impacts of stringency policy and economic support policy on CO2 emissions. © 2022, Emerald Publishing Limited.
ABSTRACT
The exponential spread of the coronavirus in Malaysia has caused a significant majority of the economic activities to cease, resulting in poor stock market performance. This pandemic situation has in turn prompted the government to introduce policies to restart and improve economic activity and stock market performance. Hence, does the government’s interference in attempting to control the outbreak of COVID-19 disease, play an important part in affecting the level of economic activity and stock market performance? To resolve this doubt, the impact of government policy responses to COVID-19 in the case of Malaysia was investigated. The sample period of the study was from 28 January 2020 till 29 May 2020, amounting to a total of 84 observations. The findings reveal that the responses taken by the government, such as staying at home requirements, closure of workplaces and debt or contract relief for households, significantly affected both economic activity and stock market performance in the country. Based on the results, these responses appear to have significant policy implications, particularly in displaying that debt or contract relief for households have negative impacts on the economic activities, but a positive impact on the stock market. © 2021 Penerbit Universiti Kebangsaan Malaysia.
