Sectoral volatility spillovers and their determinants in Vietnam

Using the vector autoregression (VAR) connectedness approach, this paper investigates dynamic volatility spillovers across 14 sectors in Vietnam's stock market over the period 2012–2021. The study also explores the differences in sectoral spillovers before and after the outbreak of Covid-19 pandemic. Additionally, the paper also investigates the effects of the current pandemic and macroeconomic fundamentals on intersectoral connectedness in Vietnam. Our findings show that volatility transmission across sectors fluctuates significantly over the research period and spikes during the Covid-19 pandemic. The total spillover index is approximately 64.23 per cent, indicating that volatility spillovers across the Vietnamese sectors are substantial. The risks from the stock market appear to spread quickly and easily across sectors in Vietnam. Among these 14 sectors, food, fisheries, and oil and gas act as net senders of risks while real estate and pharmacy are the greatest receivers of risk. The findings also confirm that the commerce, transportation, manufacturing, and service sectors are more sensitive to the Covid-19 pandemic crisis than other sectors in Vietnam. Furthermore, the empirical results show that an increase in daily Covid-19 infections increases volatility spillover across sectors. Policy implications have emerged based on these findings from this paper for the Vietnamese government and other emerging countries.

Potential impact of Covid-19 pandemic on fisheries export sector in Indonesia: literature review and pointer of future research agenda

The increase in the export volume of fishery products during the Covid-19 pandemic shows that the fisheries sector contributes to the national economy. This study aims to analyze the factors that cause fishery export performance to experience a positive trend during the Covid-19 pandemic. The study systematically reviews the literature to identify, assess, and interpret all available research evidence to answer specific research questions. The results showed that in the case of fish and shrimp export performance, the Covid-19 pandemic had a positive impact, but previous studies generally showed negative results.

Effects of COVID-19 on coastal livelihoods in the central region of Ghana.

The COVID-19 outbreak effects and related state responses, especially mobility restriction interventions, contributed to disruption in livelihoods in the coastal communities in Ghana. This paper uses an ethnographic approach to analyse the effects of the COVID-19 pandemic and coping strategies adopted by small-scale fishers, fish traders and processors. We argued that focusing solely on the livelihoods of formal sector workers is problematic because it fails to consider the dynamics of informal coastal workers. Findings indicate that fishers, fish traders and processors experienced various effects on food, income, police harassment, and coping strategies, including migration, resorting to reusable face masks and food-compromising practices. Infectious diseases such as COVID-19 impact coastal people and their livelihoods. Therefore, implementing social protection measures to mitigate the effects of pandemics on livelihoods should be better coordinated and well-targeted to reach the most vulnerable. Findings from this study offer pointers to position preparedness and response efforts to future outbreaks in a similar context.

Assessing the economic effects of the covid-19 pandemic on Swedish shrimp fishers.

This paper explores the effect of the perceived risk of the Swedish people of Covid-19 on daily auctioned shrimp prices from the start of the pandemic to the end of the year 2021. This topic is of interest to see whether the government intervention in the shrimp market to aid fishers with possible losses was justified. The Swedish shrimp fishery was for a long time managed by Regulated Open Access, but in January 1, 2017, it was transformed to a Strong User Rights Fishery by the introduction of Individual Transferable Quotas (ITQs). We use empirical data from the period from 2018 to 2021. We find that auction prices were negatively affected by covid-19 cases by SEK 19.83/kg (-9.37%), and that fishers have suffered a loss of SEK 21.5 million.

Comparative analysis of first and second stage data envelopment approaches: Performance of marine capture fisheries in the European Union

I explored harvest productivity and economic efficiency of marine fisheries across European Union member states using comparative first and second‐stage data envelopment analyses, linear programming, and econometric models, based on a panel data set of technical, social, and economic data between 2008 and 2020 when the first implications of the global Covid‐19 outbreak began in the European Union. During the period, harvest productivity increased for 52 percent of the 21 member states between 2008 and 2020, with an average economic efficiency of 0.76. The economic efficiency and harvest productivity of European Union member states' fisheries fluctuated, with noticeable declines throughout the study period. Gross domestic product per capita, population size, and aquaculture production were related to performance metrics. The results are aimed to guide European Union fisheries managers to better understand how improvements in harvest productivity and economically efficient performance are achieved without constant reliance on subsidization, over‐allocation, and overexploitation.
