2. Literature review
Theoretically, COVID-19 is likely to have a big impact on global trade in several different ways. An exporting nation's increased COVID-19 load inevitably shrinks the size of the industry, which lowers export supply. Exports will decline, particularly in fields and nations where working remotely is impractical. A commodity's domestic demand as well as production may be affected by the COVID-19 load. Redirecting the amount not consumed at home to the export market can result in a net rise in exports if the decline in domestic demand outweighs the decline in output. In an economy that imports goods, the burden of COVID-19 is mostly felt due to a decline in aggregate demand. As a result of decreased incomes and fewer retail store visits, demand will decline. The short-term impact of COVID-19 on global poverty was calculated by Sumner et al. (2020). Each scenario's effect on the number of people living in poverty is calculated using the global poverty standards of $1.90, $3.20, and $5.50 per day. Because poverty levels increased after the epidemic in 1990, the outcome conflicts with the UN Sustainable Development Goal (UNSDG), which states that poverty would be almost entirely eradicated by 2030.
Chowdhury et al. (2020) made a case study on how to manage the COVID-19 pandemic's effects on the food and beverage industry. This study found that while the medium-to-long-term implications of this pandemic appear to be complex and uncertain, the short-term effects, such as product expiration, a shortage of operational capital, and restricted distributor activities, are severe. Numerous performance indicators, including firm return on investment, GDP contribution, and workforce size, are all expected to worsen with time. Additionally, companies might need to change the relationships they have with their distributors and trading partners as well as their supply chain.
IMF (2020) predicted that real GDP growth would be 3% globally and 6% in the US, making 2020 the worst recession since the Great Depression. Both agricultural trade and general international trade will be significantly impacted. The WTO has forecast a range of 13% to 32% for the potential loss in overall trade volume, but because of falling prices, it is likely to be significantly worse in value terms. Hassani and Shahwali (2020) conducted a thorough analysis of 42 countries using the computable general equilibrium (CGE) model and found that the pandemic will result in a 905 billion dollar decline in world trade. The scenario of prolonged containment will result in a $2,095 billion reduction in world trade.
According to Hayakawa and Mukunoki (2021), the COVID-19 burden has a significant negative impact on trade in exporting countries but not in importing ones. Exports from developing countries are negatively impacted by exporters' COVID-19 burden, but not those from wealthy nations. They further argued that an exporter benefits from the burden of COVID-19 in its neighboring countries. Importers' COVID-19 load benefits trade in the agricultural sector, but exporters' COVID-19 burden hurts it, particularly in the textile, footwear, and plastics sectors. Dhinakaran and Kesavan (2020) discussed the stagnation of India's exports and imports during COVID-19. The authors concluded that during the COVID-19 shutdown, India's export and import declined. Following the COVID-19 shutdown, the national and state governments of India must deal with several social, economic, political, and institutional issues.
Maliszewska et al. (2020) assessed the likely effect of COVID-19 on GDP and trade using a standard global computable general equilibrium model. The study suggested that the pandemic causes a 2% decline in GDP worldwide, a 2.5% decline in poor countries, and a 1.8% decline in industrialized ones. In an improved pandemic scenario where containment is anticipated to take longer and now seems more likely, the declines are almost 4% lower than the global average. The output of pandemic-affected home services as well as traded tourism services show the highest negative shock. According to Gruszczynski (2020), the COVID-19 pandemic's effects are most palpable in the global services sector. The main losers are international tourism, passenger air travel, and container transportation. Both international financial transactions and the use of information and communication technology services have sharply declined.
Barichello (2020) predicted that trade in agricultural products will be less impacted in Canada because of its relatively low-income elasticity of demand. However, it is reasonable to expect a 12%–20% fall in the actual transaction value. Grain exports will be the least impacted among agricultural exports, but Canada can be expected to take part. Canada will have the best chances in the grains group because it has the lowest income elasticity. Furthermore, the Canadian wheat business will profit if more widespread export restrictions are implemented, such as those for wheat. Livestock, pulses, and horticulture are predicted to have a bigger trade decline because of the significant loss of purchasing power in many importer nations.
Islam and Fatema (2023) argued that the Covid-19 pandemic affected business and trade through two different channels such as supply shock due to the disruptions of global supply chains and demand shock due to the lower income of the people caused by job losses. The pandemic is projected to have a considerable impact on worldwide trade due to its complex implications on supply chains and other economic and financial problems (Chowdhury et al., 2021; Donthu & Gustafsson, 2020). A rise in imports from other nations may result from this decline in trade prices. On the other hand, negative production shocks brought on by COVID-19 in one country may reduce production in other nations via supply-chain networks (Hayakawa & Mukunoki, 2021). The pandemic has had a significant impact on the world's supply chain since the only way to effectively stop the virus from spreading is to impose a rigorous lockdown that restricts people's movement (ADB, 2020). In addition, the pandemic has reduced output since demand has decreased as a result of lockdowns and other emergency measures. Demand has been impacted by consumers' hesitation to spend money right now all across the world. This phenomenon can be explained by greater uncertainty and a generalized fear of losing money (due, for instance, to unemployment).
According to Zayed et al. (2021), international trade will suffer during a pandemic because there will be less demand for goods and services on a global scale. The travel, tourism, and building industries would all suffer as a result. The world's reserves of commodities and supply chain may be in danger. Both the governmental and commercial sectors in emerging nations may be able to grow their debt due to the accessibility of low-interest loans. The COVID-19 tragedy will hurt the world economy.
Segal and Gerstel (2020) argued that the growth of COVID-19 interferes with government commitments and the supply chain. The virus worsens economic uncertainty, as the financial crisis of 2008 demonstrated. Due to COVID-19's effects on the Chinese economy, automobile sales in January and February were reduced by a record 80 percent and exports by 17.2 percent. The global COVID-19 epidemic is predicted to cause a 1.5 percentage point slowdown in the global economy in 2020. The social distancing motto will pose problems for tourism and travel-related companies. The manufacturing sector will suffer as a result.
According to Liu et al. (2021), a country's imports from China were significantly reduced by its own Covid-19 deaths and lockdowns. They suggested that the pandemic's negative effects on demand outnumbered those on supply. However, Covid-19 deaths in a nation's main trading partners (apart from China) lead to an increase in imports from China, somewhat offsetting the nation’s effects. They also considered how the pandemic would affect China's exports to the world and its purchases from the world in 2020 and concluded that the path of causation is not linear. Instead, several aspects of the pandemic are likely to have an impact on international trade, including its direct health impact and the behavioral changes that result in the affected countries, the effects of the government's measures to stop the virus's spread, and the effects in third countries as a result of the pandemic's impact there.
Evenett et al. (2022) conducted a study on trade policy remedies for the COVID-19 pandemic crisis. A descriptive evaluation of the trade policy responses to the COVID-19 epidemic is what this article aims to do. The analysis discovered significant country-level heterogeneity in both the use of trade policy and the sorts of measures adopted. A few nations took steps to limit exports and ease imports, while others focused exclusively on one of these margins, and a large number did not utilize trade policy at all. The observed variability raises several research concerns about the factors that led to trade policy responses to COVID-19, how these measures affected trade and the pricing of important goods, and about how trade agreements affected the use of trade policy.
The above discussion on literature shows that several studies anticipated the potential impact of COVID-19 on global trade as well as the trade in different sectors of a specific country or group of countries. It should be crucial to identify the simulated effect of the pandemic on trade and to compare the potential effect and actual performance of a country. As the economy of Bangladesh is highly dependent on trade, it is a probable simulated effect of COVID-19 on its trade and makes a comparison with the actual trade performance of the country to provide the actual trade performance scenario.
A descriptive analysis of the macroeconomic effects of Covid-19 on Bangladesh was done by Ahamed (2021). They argued that although the economy was not in danger as a result of the immediate economic shock of COVID-19, long-term shockwaves from global uncertainty can be very harmful. An integrated macroeconomic framework architecture is crucial for the economy since the shock in the informal sectors is difficult to understand. Policymakers need to be aware of the circumstance and take decisive action. Kumar and Nafi (2020) found that Bangladesh has experienced an adverse impact on inbound and outbound tourism. The intensification of COVID-19is predicted to cause a long-term adverse impact on tourism in Bangladesh. Alam et al. (2020) argued that the magnitude of the economic losses of the pandemic in Bangladesh will depend on how the outbreak evolves as any pandemic disease and its economic consequences are vastly ambiguous which makes it challenging for policymakers to work out an axiomatic and appropriate macroeconomic policy guideline.
However, none of the studies focused on identifying the potential effect of COVID-19 on the trade performance of Bangladesh caused by the demand stick and trade disruptions due to higher trade costs resulting from the pandemic. This study attempts to fill up this above-mentioned research gap. It identifies the trade scenarios during the pandemic with descriptive data, the simulated trade scenario in different sectors under different level shocks caused by COVID-19 using a computable general equilibrium (CGE) model using the GTAP database. It finally analyzes the effects of different levels of demand shock and trade disruptions caused by trade costs due to the Covid-19 pandemic on export and import during the pandemic and compares them with the actual data.
