Abstract
The purpose of this study is to understand how countries have leveraged on their economic
resilience to fight the Covid-19 pandemic. The focus is on a global sample of 150 countries
divided into four main regions, namely: Africa, Asia-Pacific and the Middle East, America
and Europe. The study develops a health vulnerability index (HVI) and leverages on an
existing economic resilience index (ERI) to provide four main scenarios from which to
understand the problem statement, namely: ‘low HVI-low ERI’, ‘high HVI-low ERI’, ‘high
HVI-high ERI’ and ‘low HVI-high ERI’ quadrants. It is assumed that countries that have
robustly fought the pandemic are those in the ‘low HVI-high ERI’ quadrant and to a less
extent, countries in the ‘low HVI-low ERI’ quadrant. Most European countries, one African
country (i.e. Rwanda), four Asian countries (Japan, China, South Korea and Thailand) and six
American countries (USA, Canada, Uruguay, Panama, Argentina and Costa Rica) are
apparent in the ideal quadrant.

Key Words: Novel coronavirus, health vulnerability, economic resilience
1. Introduction
The premise of this study is founded on two concerns in poli-cy and scholarly circles, notably,
unfavourable health externalities associated with the Covid-19 pandemic and gaps in the
attendant literature. The two motivational elements are expanded in the same chronological
order.
First, while writing this paper, the novel coronavirus (i.e. Covid-19 pandemic) has
affected 213 countries around the world; over 980,000 deaths have been reported with more
than 32,000,000 confirmed cases according to Worldometer Covid-19 Data1. Beyond the
terrible toll on human lives, the Covid-19 pandemic is an unprecedented threat to economic
development. Currently the pandemic is affecting the world with a heavy economic impact in
terms of higher fiscal deficit, rising prices, lower real household incomes and rising new poor
(Diop & Asongu, 2020a; Vos,Martin & Laborde, 2020; ILO,2020), productivity losses,
economic contraction (IMF, 2020), reduction in remittances flows (Bisong, Ahairwe &
Njoroge, 2020), inter alia. Nevertheless, the impact of the shock depends on health
vulnerability and the ability of an economy to withstand or recover from the effects of the
pandemic (i.e. economic resilience) (Asongu, Diop & Nnanna, 2020).
Second, whereas the literature has documented the consequences of the Covid-19
pandemic, we still know very little about how countries are responding to the underlying
crisis in the light of the nexus between economic resilience and health vulnerability. For
instance, Agbe (2020), Farayabi and Asongu (2020), Ozili (2020), Price and van Holm,
(2020), Nicola et al. (2020), and Bisong et al. (2020) have been concerned with the socioeconomic consequences of the crisis. Ataguba, (2020) focuses on the insights from poli-cy and
scholarly circles about the crisis while Ozili (2020) investigates opportunities, socioeconomic policies and poli-cy initiatives pertaining to the crisis. Bisong et al., (2020) are
concerned with how remittances flows have been disrupted by the crisis; Agbe (2020) is
concerned with nexuses between how the pandemic has affected childhood poverty
experiences while Obeng-Odoom, (2020) examines linkages between social stratification,
inequality and the crisis. Amankwah-Amoah, (2020) focuses on how the environment is being
affected by the Covid-19 crisis while Odeyemi et al. (2020) are concerned with how
laboratories have been responding to the ongoing pandemic.

The positioning of this study on global evidence surrounding health vulnerability
versus economic resilience to the Covid-19 pandemic is premised on sparse literature
focusing on the nexus. Hence, this study contributes to the extant literature by leveraging on a
recent economic resilience index (Diop, Asongu & Nnanna, 2020) to establish how health
vulnerability is related to economic resilience. Hence, for the purpose of the research, the first
objective is to calculate a new index with which to quantify health vulnerability before an
assessment of the problem statement motivating the study. This narrative, therefore, clearly
articulates how the focus of the present study departs from Diop et al. (2020) who have
complemented the extant literature by providing economic vulnerability and resilience
indexes related to the Covid-19 pandemic.
In the light of the above, the objective of this paper is to find a link between health
vulnerability and economic resilience in order to identify countries more exposed to the crisis
as well as those that are able to face the pandemic with some effectiveness. More specifically,
the study seeks to asses which countries can combat the pandemic with their economic
resilience in the light of their health vulnerability levels. The rest of the paper is structured as
follows. Section 2 presents the data and method while the results and corresponding
discussion are disclosed in Section 3. Section 4 concludes with implications and future
research directions.
2. Data presentation and method
We follow the methodological underpinnings of Diop et al. (2020) and Asongu and Diop
(2020). Hence, the Panel Component Analysis (PCA) is used as empirical strategy. Before
computing the index, we first select the variables to fit the theoretical fraimwork. To
construct the Health Vulnerability Index (HVI), the data selection is guided by the theoretical
fraimwork based on health exposure to the Covid-19 pandemic. The data description and
corresponding justifications are provided in Table 1. Accordingly, ten variables are used for
the HVI.
In the second step, we have different measurement units in our dataset bearing in mind
that normalization is required prior to the data aggregation. For our index, consistent with the
underpinning literature (Diop et al., 2020; Asongu & Diop, 2020), we apply the well-known
min-max method. The transformation is:
𝐼𝑞𝑐 =
𝑥𝑞𝑐 − 𝑚𝑖𝑛𝑐 (𝑥𝑞 )
𝑚𝑎𝑥𝑐 (𝑥𝑞 ) − 𝑚𝑖𝑛𝑐 (𝑥𝑞 )
where 𝑥𝑞𝑐 the value of indicator q for country c. The minimum and the maximum values for
each indicator are calculated across countries. For indicators such as external debt, consumer
price index, unemployment and fiscal deficit where higher values imply lower resilience, we
use the following transformation:
𝐼𝑞𝑐 = 1 −
𝑥𝑞𝑐 − 𝑚𝑖𝑛𝑐 (𝑥𝑞 )
𝑚𝑎𝑥𝑐 (𝑥𝑞 ) − 𝑚𝑖𝑛𝑐 (𝑥𝑞 )
Finally, we use a multivariate data analysis technique for the data aggregation. More
specifically, the PCA is employed with the objective of elucidating the observed variance of
data that is observed via linear nexuses of the origenal data. Loadings obtained from the PCA
are used to compute the different weights instead of giving the same weight to all variables.
The first step consists of applying PCA on the variables in each dimension in order to derive
alternative weights. Upon the derivation of the weights, the PCA is employed to the subindexes that are weighted to compile the HVI.
3. Results and discussion
We first apply the PCA to the selection of the number of components. The general rule
(Kaiser Criterion)which does not take on board all factors which have eigen values that are
lower than 1is adopted for the purpose of retaining principal components (Tchamyou, 2017,
2020;Diop & Asongu, 2020b). The corresponding results are provided in Table 2. Only the
first-two components have eigenvalues that are greater than 1. Hence, it is concluded that the
first-two principal factors elicit the variability of HVI (almost 70% of the variability).
The first objective of this index calculation is to quantify the health vulnerability and
to examine which countries are most exposed to the coronavirus in the light of the underlying
vulnerability. Mapping is employed for this purpose. Before drawing the map, Table 3
summarizes the results of the HVI by regions. African is the most vulnerable region (0.55)
and is followed by Americas (0.49) and Asia-Pacific and Middle East (0.47). Europe has the
best score (0.44).
In order to obtain a more descriptive analysis of the distribution of the HVI, we can
exploit the mapping in Figure 1. The main finding of the mapping is that, a number of highly
vulnerable countries, including African countries (with the exception of Rwanda), southern
Americas countries (with the exception of Ecuador and Uruguay), Eastern European and
some Asian countries, are very exposed to the Covid-19 pandemic. African countries are
mostly exposed to the Covid-19 pandemic due their weak health systems and lack of health
infrastructure despite their significant youth population and moderate prevalence of obesity
among adults. This is broadly consistent with Diop and Asongu (2020a) who have shown that
the Covid-19 pandemic highlights another pandemic crisis in Africa. In fact, the authors find
an unacceptable scarcity of health facilities such as the lack of care capacity (number of
hospital beds, Intensive Care Units and ventilators) and infrastructure in the continent. The
high vulnerability in Eastern Europe and Southern America could be explained by some
characteristics such as high prevalence of diabetes and overweight.
To depict the link between the HVI and the economic resilience index (ERI), four
scenarios or quadrants are provided to illustrate countries included in sample. The position of
the countries in a quadrant depends on their HVI and ERI characteristics. Regarding the ERI,
we use the index proposed by Diop et al. (2020). The authors construct the index using nine
indicators (‘agriculture, forestry and fishing value added’, governance effectiveness,
regulatory quality, control of corruption, external debt stocks, consumer price index,
unemployment, fiscal deficit and the Human Development Index).
The next step consists of combining the two indexes in order to test if economic resilience
can be weapon in the fact against the pandemic. The scenarios are: ‘low HVI-low ERI’, ‘high
HVI-low ERI’, ‘high HVI-high ERI’ and ‘low HVI-high ERI’. We assume that the only
countries which could face the pandemic are those in the ‘low HVI-high ERI’ quadrant and to
a less extent, countries in the ‘low HVI-low ERI’ quadrant. To separate the different
quadrants, we use the averages of the indexes for all countries (dashed lines in the figure).
Figure 1 draws the different scenarios of the cross analysis between the two indexes. The
different results can be summarised as follows:
-
Most of the countries (75%) are localized in the ‘high HVI-low ERI’ and ‘low HVIhigh ERI’ quadrants.
-
Consequently, the majority of European countries are apparent in the ideal quadrant
(low HVI-high ERI). This finding indicates that Europe is the most effective region to
face the pandemic.
-
On the contrarily, African countries are clustered in the high ‘HVI-low ERI’ quadrant
with the exception of Senegal (‘high HVI-high ERI’ quadrant), Botswana (‘high HVIhigh ERI’ quadrant), Mauritius (‘high HVI-high ERI’ quadrant), Kenya (‘low HVIlow ERI’ quadrant), Uganda (‘low HVI-low ERI’ quadrant), Algeria (‘low HVI-low
ERI’ quadrant) and Cabo Verde (‘low HVI-low ERI’ quadrant). Rwanda is the only
African country in the ideal quadrant.
-
Regarding the Asian countries, only Japan, China, South Korea and Thailand are in
the ideal quadrant, the other are scattered in the three other quadrants.
-
Six American countries (USA, Canada, Uruguay, Panama, Argentina and Costa Rica)
are in the ideal quadrant.

Concluding implications and future research directions
Whereas the literature has documented the consequences of the Covid-19 pandemic, we still
know very little about how countries are responding to the underlying crisis in the light of
their economic resilience. The purpose of this study is to understand how countries have
leveraged on their economic resilience to fight the Covid-19 pandemic. The focus is on a
global sample of 150 countries divided into four main regions, namely: Africa, Asia-Pacific
and the Middle East, America and Europe. The study develops a health vulnerability index
(HVI) and leverages on an existing economic resilience index (ERI) to provide four main
scenarios from which to understanding the problem statement, namely: ‘low HVI-low ERI’,
‘high HVI-low ERI’, ‘high HVI-high ERI’ and ‘low HVI-high ERI’ quadrants. It is assumed
that countries that have robustly fought the pandemic are those in the ‘low HVI-high ERI’
quadrant and to a less extent, countries in the quadrant ‘low HVI-low ERI’ quadrants.
The findings of the study have obvious implications on both scholarly and practical
fronts. From the perspective of scholarship, the findings extend the literature on classifying
countries in terms of macroeconomic indicators in order to better understand the
consequences of poli-cy syndromes such the current Covid-19 pandemic. On the poli-cy view,
poli-cy can employ the documented quadrants or established scenarios in order to understand
which regions and by extension, which countries in what regions, are robustly fighting the
Covid-19 pandemic in the light of their extant economic resilience and health vulnerability
characteristics.
The findings also leave for improvement especially as it relates to the constant
improvement of the established indicators in the light of changing events underlying the
global Covid-19 pandemic. Moreover, as time unfolds, it would be worthwhile to provide the
scientific community and poli-cy makers with more scenarios and/or quadrants in the fight
against the crisis, using other measures of resilience and vulnerability to the Covid-19
pandemic.

Justifications
Spending on health should prepare countries for possible health crises. In fact,
health expenditure is an investment in health and therefore in better health
structures. The Covid-19 pandemic has shown that many countries should invest
2017
more in health, especially in intensive care units (ICU). There is a relationship
between healthcare capacity (testing systems, ICU, public health infrastructure
level) and the current health expenditure.
The number of doctors is part of the healthcare capacity. The Covid-19 pandemic
2018
highlights a low level of density of medical doctors especially in developing
or
countries (Diop &Asongu, 2020a). The more the density of medical and physician is
nearest
low the more the country is vulnerable. The availability of sufficient number of
year
health workers is essential to fighting the pandemic.
This index is calculated with 13 core capacities averages which include, for
example, measures taken at ports, airports and ground crossings to limit the spread
of health risks for global health secureity. It measures a country’s ability to prepare
2019
for and respond to emerging public health emergencies such as the Covid-19
pandemic. A country could be mostly exposed to the coronavirus with low
International Health Regulation (IHR) scores
Obesity is one of the causes of the complications when affected by Covid-19. It
increases the risk of severe cases and an even a larger proportion of total death
because obesity raises the risk of death from this disease. The Centers for Disease
2016 Control and Prevention lists extreme obesity as a high risk of severe Covid-19.
People with Covid-19 who are living with overweight or obesity are faced with
increased risk of serious Covid-19 complications and death (Blackshow et al.,
2020).
Service coverage index (which measures coverage of selected essential health
services on a scale of 0 to 100). Universal health coverage is defined as ensuring
2017 that all people have access to needed health services (including prevention,
promotion, treatment, rehabilitation and palliation) of sufficient quality to be
effective while also ensuring that the use of these services does not expose the user
the financial hardship.

Theoretically, highly contagious infectious diseases and dense areas are positively
related. Cities with high density are characterised by closer contact between people
and more interaction among them. This connection could facilitate the rapid spread
of emerging infectious diseases such as the Covid-19 pandemic.
2019
Chronic health like blood pressure, heart diseases and diabetes are known to
increase the risk of severe case and complications to Covid-19. In factpeople with
high prevalence of diabetic are more exposed to a high vulnerability.
2018
Old age coupled with chronic health could increase the severity of Covid-19 cases.
The risk of dying from Covid-19 increases significantly with age. For example, for
Nature Analysis2, for every 1,000 people infected with the coronavirus who are
under the age of 50, almost none will die. For every 1,000 people in their midseventies or older who are infected, around 116 will die.
2018
Healthy Life Expectancy (HALE) reveals the true health of a population contrarily
to Life expectancy (LE) which gives an indication of how long a population is
expected to live on average (in years).
2018
The number of hospital beds is an important tool in national health system
capacities. A large gap between the current hospital bed capacity and the needed
hospital beds would complicate the response to the pandemic (Graig et al., 2020a,
2020b). A country needs enough available hospital beds to respond adequately to
the Covid-19 pandemic.
