The Impacts of Ongoing Health Crisis Caused by Novel Coronavirus “COVID-19” on the Economics of the Countries

This study examines the impact of COVID-19 cases on GDP growth and Unemployment in developed countries represented by Germany, France, and Spain and developing countries represented by Mexico, Uruguay, Brazil, Turkey, and China. Various statistical tests were employed; ADF-Fisher Chi-Square for stationarity, Pedroni Cointegration test, Hausemn test, and panel granger causality test. The empirical results suggest that data from developed and developing countries are stationary at I (1). The Pedroni cointegration test revealed no long-run relationship between the dependent variables (Covid cases) and independent variables represented by GDP growth and Unemployment. The Hausman test showed that the fixed effect model is suitable for this study. The fixed effect model’s estimation suggests that there is a positive and significant association between COVID-19 with unemployment rate and GDP growth in industrialized countries. However, in developing countries, the rise in COVID cases causes a decrease in GDP growth and Unemployment. The study contribution is critically significant for policymakers and scientists to set a plan for the comprehensive economic recovery for the world after the pandemic.


Introduction
Coronavirus is an illness caused by SARS-COV-2 (Gorbalenya et al., 2020). It was named COVID-19 by the WHO, which derived from "corona disease 2019" countries have witnessed a decline in economic activity and a rapid increase in Unemployment in a short time. Spain is from the countries that suffered from a financial crisis from 2008 to 2014 caused by the housing bubble and the accompanying of unsustainably high GDP growth. The country is still grappling with recovery since 2015; it has been struggling for the past years with debt. Another country that could be plunged into a deep recession is France. According to the national statistics institute, France's economy shrank by 13.8% due to the lockdown; the negative economic development resulted from shutting down essential activities in the country. As the COVID-19 spread worldwide, lockdowns were one reason for the collapses of businesses that play a significant role in the country's rising number of jobless people. Developed countries suffered from the spread of the pandemic, and emerging nations took their share of this virus. According to the United Nations Development Program (UNDP), developing countries could face an income loss of $220 billion.
The International Monetary fund (IMF) reported that because of COVID-19, the world's economy is going through its worst turndown since the great depression in the 1930s. Oxfam International, in its report, predicted that half a billion people could be pushed into poverty as a result of the pandemic, COVID-19. As a response to the pandemic, precautionary measures were executed by airline companies and other manufacturing companies to prevent the spread of the virus among the people. Consequently, many countries are falling behind, and it will take them many years to recover. Therefore this research will mainly show the relationship between Corona cases with the GDP growth and Unemployment in both developing and developed countries. This paper is constructed in four main parts; first an introduction and objective of the study, methodology used in the paper, discussion and results and conclusion.

The Objective of This Study and Questions
Since many studies depended on descriptive analysis to show the impacts of CO-VID-19, this study used the statistical approach to determine the effects of the ongoing health crisis caused by Novel Coronavirus "COVID-19" on GDP growth and Unemployment in developed, developing countries. Furthermore, the study understands better the COVID-19 impacts on the nation's real economic growth and unemployment rate.
The key objectives of the study are; 1) To determine the significance of the Impact of COVID-19 on GDP growth in Developed, developing, and least developing countries.
2) To analyze whether there is a long-run effect of the rise of COVID-19 cases on the economic growth and Unemployment for developed and developing countries.

Study Design and Conceptual Framework
This is a quantitative analytic study to identify the association of the COVID-

Multiple Regression Model
Regression model for developed countries and developing countries LCOVID.V = β0 + β1LGDP + β2 LUNEMP + ui (1) LCOVID.V is the natural logarithm of COVID-19 in the reported countries. LGDP is the natural logarithm of GDP growth in the reported countries, β2 = The slope coefficient of Unemployment, LUNEMP is the natural logarithm of GDP growth in reported countries, ui = the error term of the equation.

Unit-Root Test Results (ADF)
ADF-Fisher Chi-Square Test  The unit root test is an important econometric procedure to examine the data's stationarity; if the data is non-stationary, the R square will be high, which shows variables do not exist. When data is not stationary, it does not have economic meaning. Therefore, it is critical to investigate the stationarity of the data using the augmented dicky Fuller test. The null and alternative hypothesis The Null and alternative hypothesis are as follow H0: δ = 1 unit root (Variables is not stationary), H1: δ < 1 no unit root (Variable is stationary).
If the coefficient is less than one, then the hypothesis of y contains a unit root is rejected. The rejection of the null hypothesis means the variables are stationary and have a unit root test; however, if it is one or more, we accept the null hypothesis, which means that variables have unit root and are not stationary.

The Panel Cointegration Test
The Pedroni cointegration test was first developed by Pedroni (2004). It was used to determine the cointegration between the variables in the panel data. Pedroni developed seven statistic tests to examine the panel cointegration between variables. There are two categories for the Pedroni test; the first group contains four tests within dimensions. The other group has three tests between dimensions (Asteriou & Hall, 2007). The within dimension group termed as the panel cointegration statistics, and the between dimensions statistics are called group-mean cointegration statistics.
Pedroni test introduces seven tests that examine the null hypothesis of no cointegration. These seven tests allow heterogeneity in the panel in the short and long run. According to Güvenek and Alptekin (2010), the Pedroni test permits the effects between the cross-section of the panel to be different. Additionally, it also allows the differentiation of the cross-section of the cube under the alternative hypothesis.

Fixed Effect Model vs. Random Effect Model
The fixed effect model is a statistical model in which the values of independent variables do not change (constant) while the dependent variable value changes as a response to the independent ones. According to Allison (2009)

Hausman Test
The Hausman (1978) Test is conducted in this study in order to choose between the fixed effect model or the random effect model. The null hypothesis of the Hausman test suggests that the random-effects model is appropriate. In contrast, the alternative hypothesis indicates the suitability of using the fixed effects model.

Granger Causality Test
According to Gujarati and Porter (2009), Granger causality is a hypothesis test to determine whether one variable helps in predicts another one. For example, suppose A granger causes B. In that case, it means that A contributes to forecasting B. Additionally, the granger causality test shows and explains the association between the dependent and independent variables. Table 1 shows the stationarity of the data in both developing and developed countries. After conducting the ADF Fisher Chi-square test, it can be noticed that in developed countries and developing countries, variables were only stationary at first difference. However, GDP growth showed stationarity in both I (0) and I (1). The p values of all variables are less than the 10% significance; therefore, we reject the null hypothesis and declare the stationarity of the data. Therefore the data results are consistent and reliable

Pedroni Cointegration Test
From the panel Pedroni cointegration results; Table 2 suggests only one out of the seven statistics reject the null hypothesis of no cointegration and imply the variables are cointegrated. However, six of the seven statistics fail to reject the null hypothesis of no cointegration. These six tests are Panel rho test, Panel P.P. statistic, Panel ADF test, Group rho test, Group PP-stat and Group ADF-Stat.
Since most tests imply no cointegration, it is concluded that there is no cointegration between the variables. In other words, COVID-19 does not have an impact on Unemployment and GDP growth in the long run in both developing and developed countries.

Hausman Test
By conducting the Hausman test to determine which model to use; fixed effect

Fixed Effects Model
According to the fixed effects model (Table 4), it is noticed that Unemployment and GDP share a positive relationship with COVID-19 cases since the p-value of both variables is less than 5% and both of the coefficients are positive for GDP and Unemployment with 20,495.24 and 337,041.6, respectively in Developed countries. On the other hand, in developing countries, GDP shares a negative and insignificant relationship with COVID-19 cases since the p-value of both variables is more than 5%. However, with p-values less than 1%, Unemployment shares a positive and significant relationship with COVID-19 cases. In a similar study, Aycock and Chen (2021b) investigate the impact of economic development and the spread of COVID-19; results showed that there is a positive correlation between economic growth and COVID-19 in U.S. and some European countries.
Aycock and Chen (2021b) suggested a higher level in economic growth contributing to the spreading of COVID-19 and infectious diseases. Sira and Woldetensay (2020) carried out a study on the impact of COVID-19 on Unemployment and GDP growth in Ethiopia; they concluded that COVID-19 contributes to the increase of Unemployment and a decrease in GDP growth.

Granger Causality Test
The causality test is performed to find out the association between the variable.
The results indicate the presence of bi-directional and unidirectional causality between the variables. The study results in developed countries suggested that   there is bidirectional causation that runs from COVID-19 cases to GDP and vice versa. Additionally, a unidirectional association runs from Unemployment to CO-VID19 since the P-value is less than the 5% significance. Furthermore, findings show that COVID-19 does not help in forecasting unemployment. However, in developing countries, we can conclude that neither GDP nor Unemployment contributes to forecasting the COVID-19 and vice versa. (Table 5) 4. Discussion

The Relationship between COVID-19 and GDP Growth in Developed and Developing Countries
The empirical findings from the developed countries show that there is a positive and significant association of COVID-19 cases with GDP growth; the result of this study is consistent with Aycock and Chen (2021b) and Aycock and Chen (2021a). The study suggests that developed countries with higher level of GDP growth are more risky in facilitating infectious disease spread due to advanced transportation. In developed countries, people normally tend to live in large cities where they move from a place to another easily through the abundant transportation tools. Furthermore, the symptoms of COVID-19 might appear after two weeks, and in some cases, infected people might not develop any symptoms at all. This made the virus to be transmitted without even knowing through moving from a place to another. Moreover, developed countries have the capacity to detect cases and register them due to strong surveillance systems and the capacity for testing-also, awareness of people to seek health services better than developing countries. Additionally, people who live in developed countries enjoy high living standards that allow them to do activities, travel around, and attend concerts, increasing their chances of being infected.  On the other hand, developing countries and low-income countries are in a difficult position to respond to the COVID-19 crisis. The study suggests that when COVID-19 cases increase in developing countries, economic growth decreases and countries' income becomes less and less. Developing and emerging countries are in a vulnerable position even before the COVID-19 crisis; many countries are in public debt and barely standing on their feet. After imposing a lockdown in many countries, exports and imports declined, businesses shut down, and airline companies lost a significant amount of money. The united nation conference on trade and development (UNCATAD) predicted that developing countries are threatened to lose 850 billion export revenue due to the COVID-19 crisis. The international community is the key the help developing nations to contain the virus by providing priorities such as health supplies, food, medicines, and vaccines. As a result of the collapsing economies, the international monetary fund provided funding to many developing countries by establishing long-term economic programs to help the economic sustainability for developing countries.
Furthermore, the study suggests that there is no long-run association of CO-VID-19 with GDP growth and Unemployment. Ozparlak (2020) studied the impact of COVID-19 on economic variables; his findings show that Italy and France and the USA have no long-term relationship with COVID-19 cases. The effects of the pandemic, in the long run, will depend on the response of the country.
The expected scares will vary depending on the economy's structure and authorities' policy response (Jackson et al., 2020). China has enjoyed a fast recovery as the pandemic became under control; the domestic market had a quick recovery by 80% of the pre-crisis (Czerny et al., 2021). Additionally, it also witnessed a strong rebound comparing to the first quarter in 2020. Nevertheless, Europe, on the other side is struggling to recover from the impact of the COVID-19 crisis. According to Wijffelaars (2020), Spain could not fully control the second wave of the spread of the virus, which remarkably had a huge impact on tourism as it accounted for 15% of the country's GDP. From both cases, it can be concluded that the economic recovery is based on the speedy control of the pandemic. Therefore with limited healthcare in emerging countries, the impact will be more severe in developing countries than the developed ones.

The Relationship between COVID-19 with Unemployment in Developed and Developing Countries
Statistically, the study suggests that due to the increase of COVID-19 cases, demand for labor shrank to its lowest level, causing a rapid increase in the unemployment rate worldwide. During the COVID-19 pandemic, Unemployment was a problem for both developing and developed countries. Many people lost their jobs, especially after enforcing the lockdown and taking containment measures. Social distancing and movement restrictions force many small and medium businesses to collapse and shut them down. Low-income countries' risks are not limited to the higher unemployment rate and withheld wages. However, also it could fall deep into hunger and long-lasting poverty. Therefore Policymakers and authorities should implement fiscal and monetary policies to help in the global economic recovery. Governments should provide industries with financial aid and remit them from a proportion of tax income. National banks should adopt an expansionary monetary policy by lowering the interest rate to encourage investors to invest, consumers to spend, and businesses to achieve profits. International Monetary Fund (IMF, 2020) stated that COVID-19 is the storm that destroyed jobs, worsening poverty, and creating debt, especially for countries and firms in vulnerable situations. This economic disruption will leave scars in the long run. However, as the study suggests, there will not be certain longrun effects of the COVID-19 cases on Unemployment. With the availability of vaccination, many countries started to ease restrictions, leading to restaurants and small businesses opening to employ many people who lost their jobs during the pandemic. The latest data show that 50% of the U.S. population received at least one dose.
Consequently, employment improves faster and the employment level would be back to the pre-pandemic level by mid-2021 (Davidson, 2021). Another case is Australia; it was reported that in February 2021, employment would be back to its normal state in the pre-pandemic level (Edwards, 2021). In short, the CO-VID-19 will not have long scares on employment as many countries are recovering and expected to enjoy pre-pandemic level shortly.

Recommendation
Covid-19 is still prevalent worldwide and has mutated into delta virus, cases are still increasing therefore data always changes throughout the time.

Conclusion
This research examines the factors impacts of COVID-19 cases on the GDP growth and unemployment in selected developing and developed countries. Monthly panel data was collected from January 2019 to December 2020. The study results revealed a positive and significant correlation between Covid-19 cases with the economy growth and unemployment of developed countries. Technology and advanced transportation are some of the main factors that lead to increased cases. In developed countries, health supplies are more efficient to record cases daily, while other emerging countries have a weak healthcare system and find it hard to detect viruses on time. On the other hand, in developing countries, the rise of COVID-19 causes a decline in GDP growth and increases unemployment. As COVID cases increase, governments impose lockdown policies and social distancing measures, resulting in shutting down businesses and companies.
Consequently, in developed countries, people lose their jobs and become unemployed, while in the emerging economies, the consequences could push many people under the poverty line. The research also suggests there will not be a longrun effect of COVID in the future of global economies. As vaccinations started to roll out, many countries will witness economic recovery by the end of 2021.
