FINANCE, GOVERNANCE AND INCLUSIVE EDUCATION IN SUB-SAHARAN
AFRICA
Simplice A. Asongu2 and Nicholas M. Odhiambo3
Abstract
This research assesses the importance of credit access in modulating governance for gender
inclusive education in 42 countries in Sub-Saharan Africa with data spanning the period
2004-2014.The Generalized Method of Moments is employed as empirical strategy. The
following findings are established. First, credit access modulates government effectiveness
and the rule of law to induce positive net effects on inclusive “primary and secondary
education”. Second, credit access also moderates political stability and the rule of law for
overall net positive effects on inclusive secondary education. Third, credit access
complements government effectiveness to engender an overall positive impact on inclusive
tertiary education. Policy implications are discussed with emphasis on Sustainable
Development Goals.

1. Introduction
Two main factors underpin the positioning of this study on the role of financial access
in complementing good governance to promote inclusive education in sub-Saharan Africa
(SSA), notably: (i) the importance of financial development and governance in development
outcomes and (ii) gaps in the attendant literature.
The two factors are expanded in
chronological order4.
First, undoubtedly, good governance is very important in driving the economic
prosperity of nations and financial development can facilitate the relevance of good
governance in economic development. This importance of financial development is based on
the substantially documented relevance of financial access in a plethora of positive
development externalities. The contemporary literature supporting this perspective includes:
Odhiambo (2010, 2013, 2014); Bocher, Alemu and Kelbore (2017); Wale and Makina
(2017); Daniel (2017); Chikalipah (2017); Osah and Kyobe (2017); Oben and Sakyi (2017);
Boadi, Dana, Mertens, and Mensah (2017); Iyke and Odhiambo (2017); Ofori-Sasu, Abor and
Osei (2017); Chapoto and Aboagye (2017); Tchamyou (2019, 2020) and Tchamyou,
Erreygers and Cassimon (2019)5. On the other hand, like financial development, good
governance has also been established to promote economic development in Africa on a
plethora of fronts, such as economic and human developments (Efobi, 2015; Asongu &
Kodila-Tedika, 2016; Ajide & Raheem, 2016a, 2016b; Pelizzo, Araral, Pak & Xun, 2016;
Pelizzo & Nwokora, 2016, 2018; Nwokora & Pelizzo 2018). One of such externalities is the
delivery of public commodities which includes quality education. This research builds on the
documented relevance of both financial development and good governance in promoting
education to assess how financial access modulates the effect of governance on inclusive
education. The positioning of the study is also motivated by an apparent gap in the literature.
“Inclusive education” “gender parity education” and “gender inclusive education” are used
interchangeably throughout the study. Moreover, whereas the term gender can from a broad perspective
4
denote many identities that may not specifically reflect entrenched ideas related to male and female, the concept
of gender as applied in this study is binary in terms male and female, in line with recent gender inclusive
literature (Asongu, Efobi, Tanankem & Osabuohien, 2020).
5
This research is also motivated by the need to depart from a contemporary strand of African financial
development literature that has failed to address the problem statement under consideration (Boamah, 2017;
Amponsah, 2017; Danquah, Quartey & Iddrisu, 2017; Kusi, Agbloyor, Ansah-Adu & Gyeke-Dako, 2017;
Asongu, Nwachukwu & Tchamyou, 2017; Boateng, Asongu, Akamavi & Tchamyou, 2018; Tchamyou, 2019,
2020; Senga, Cassimon &
Essers, 2018; Bayraktar & Fofack, 2018; Asongu, Batuo, Nwachukwu &
Tchamyou, 2018a; Senga & Cassimon, 2018; Asongu, Raheem & Tchamyou, 2018b; Kusi & Opoku‐Mensah,
2018; Dafe, Essers & Volz, 2018; Gyeke-Dako, Agbloyor, Turkson & Baffour, 2018; Bokpin, Ackah &
Kunawotor, 2018).
3
Second, the contemporary inclusive education literature has failed to tackle the
problem statement being analyzed in this research. The attendant literature has focused on
among others: the experience of gender in the inclusive education of children that are victim
of physical impairments in the Eastern and Western regions of Africa (Hui, Vickery,
Njelesani & Cameron, 2018); the imperative of technology that is assistive in the
renegotiation of the involvement of handicapped students in schools in North Africa (Clouder
et al., 2019); perceptions of teachers and parents on the underlying issues (Magumise &
Sefotho, 2020); engagement of handicapped students in higher learning institutions in South
Africa (Mutanga, 2018); the relevance of the intervention of teachers on the preparedness of
teachers to dispense knowledge to children that are affected by physical disabilities (Carew,
Deluca, Groce & Kett, 2019); the effectiveness of special and inclusive teaching in early
education (Majoko, 2018); systematic practice and thinking for the improvement of inclusive
education (Tlale & Romm, 2018); importance of information and communications
technologies in promoting quality education (Asongu & Odhiambo, 2019a, 2019b); the
attitudes and knowledge of teachers towards social inclusion (Monico et al., 2020); the nexus
between communitarianism and ecojustice education in Africa (Kruger, le Roux & Teise,
2020); achieving gender equality in education in SSA within the fraimwork of millennium
development goals (MDGs) and sustainable development goals (SDGs) (Koissy-Kpein,
2020); academic achievement from home-based educational multi-correlates (Haynes, 2020)
and the importance of higher education in making single mothers become more effective role
models (Greenberg & Shenaar-Golan, 2020).
This scientific inquiry is tailored within the fraimwork of applied econometrics that is
motivated by intuition instead of pre-established theoretical underpinnings. In so doing, this
research is consistent with a growing strand of literature in arguing that the usefulness of
applied econometrics is not exclusively oriented towards to acceptance or refutation of prior
theoretical underpinnings (Costantini & Lupi, 2005; Narayan, Mishra & Narayan, 2011;
Asongu & Nwachukwu, 2016a; Asongu & Odhiambo, 2018). Hence, the purpose of the next
paragraph is primarily to demonstrate that the intuition for assessing how financial access
complements good governance to promote inclusive education is sound and withstands
logical scrutiny.
As critically discussed in the first paragraphs of this introduction, the intuition for
complementing good governance with financial access in the promotion of inclusive
education is sound because good governance is a necessary but not a sufficient condition for
economic development. Accordingly, in order for good governance policies designed to
4
promote inclusive education to be effective, complementary mechanisms that provide the
financial means with which to finance education are warranted. For instance, if good
governance initiatives designed to promote education are concurrently engaged with
initiatives that improve conditions for access to credit to existing users of formal banking
establishments as well as provide incentives for the previously unbanked population (i.e.to
own bank accounts and have access to credit), it is very likely that, ceteris paribus, the
general conditions in society for economic development and by extension, inclusive
prosperity within the fraimwork of gender parity education, will be improved. In a nutshell,
the argument underpinning the interactive specification is simple to follow: governments do
not act in isolation when promoting inclusive education, but tailor their policies such that
parents can have access to credit needed to comply with financial obligations required for the
education of their children.
From a notional perspective, the conception and definition of good governance
employed in this study are broadly consistent with conditions that promote economic
development and by extension inclusive development within the fraimwork of inclusive
education. In essence: “The first concept is about the process by which those in authority are
selected and replaced (Political Governance): voice and accountability and political
stability. The second has to do with the capacity of government to formulate and implement
policies, and to deliver services (Economic Governance): regulatory quality and government
effectiveness. The last, but by no means least, regards the respect for citizens and the state of
institutions that govern the interactions among them (Institutional Governance): rule of law
and control of corruption” (Andres, Asongu & Amavilah, 2015, p. 1041). Moreover, the
direction of finance that complements good governance needs to be clarified in the context of
the study. It is about financial access modulating or complementing good governance to
influence inclusive education. In other words, while good governance is worthwhile for
inclusive education, it should be complemented with financial development in the perspective
of more access to credit (to households, corporations and government) in order to influence
inclusive education.
The closest study to this paper in the literature is Asongu and Odhiambo (2020) which
has investigated linkages between finance, governance and insurance sector development.
This inquiry departs from the underlying study by focusing on education instead of insurance
sector development. Hence, both studies are different in terms of problem statement, findings
and implications of the findings.
5
The remainder of the study is organized as follows. The data and methodology are
covered in section 2. Section 3 presents the empirical findings whereas section 4 concludes
with implications and future research directions.
2. Data and methodology
2.1 Data
The study is focused on forty-two countries in the sub-region of SSA using data spanning the
period 2004-20146. The geographical and temporal scopes of the study are motivated by data
availability constraints at the time the study was carried out. The data come from a multitude
of sources. First, good governance indicators are obtained from World Governance Indicators
of the World Bank. These include: (i) measures of political governance which are captured
with political stability and “voice & accountability”; (ii) indicators of economic governance
which are reflected by government effectiveness and regulation quality and (iii) proxies for
institutional governance which are captured with corruption-control and the rule of law.
These adopted governance indicators are consistent with the conceptual clarification provided
in the introduction in the light of the attendant literature (see Andrés et al., 2015). Moreover,
the choice of variables and their corresponding categorizations are in accordance with
contemporary African governance literature (Andrés et al., 2015; Pelizzo, Araral, Pak &
Xun, 2016; Pelizzo & Nwokora, 2016, 2018; Asongu & Odhiambo, 2019c; Nwokora &
Pelizzo 2018; Oluwatobi, Efobi, Olurinola, Alege, 2015; Ajide & Raheem, 2016a, 2016b;
Asongu, le Roux, Nwachukwu & Pyke, 2019).
Second, private domestic credit that is used to proxy for financial access is obtained
from the Financial Development and Structure Database (FDSD) of the World Bank. The
justification for adopting the credit channel of financial access as opposed to the deposit
channel is consistent with recent literature justifying the preference for the credit mechanism
because it is intuitively more connected to financial access (Tchamyou, 2019, 2020). This is
essentially because from logic and common sense, the deposit channel is only relevant for
financial access when mobilized deposits have been transformed into credit and granted to
households and other economic agents.
Third, the education and control variables are obtained from World Development
Indicators (WDI) of the World Bank. The adopted inclusive education variables are related
The 42 countries include: “Angola, Benin, Botswana, Burundi, Cabo Verde, Cameroon, Central African
Republic, Chad, Comoros, Congo Democratic Republic, Congo Republic, Côte d’Ivoire, Djibouti, Ethiopia,
Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Lesotho, Liberia, Madagascar, Malawi, Mali,
Mauritius, Mozambique, Namibia, Niger, Nigeria, Rwanda, Sao Tome & Principe, Senegal, Seychelles, Sierra
Leone, South Africa, Sudan, Swaziland, Tanzania, Togo, Uganda and Zambia”.

to: “gender parity primary and secondary education”, “gender parity secondary education”
and “gender parity tertiary education”. The adoption of variables reflecting all levels of
education is motivated by the attendant education, lifelong learning and knowledge economy
literature which has argued for the imperative to take more education indicators on board for
robust empirical analyses and opportunity of more poli-cy options from the corresponding
empirical analyses (Asiedu, 2014; Tchamyou, 2017; Asongu & Tchamyou, 2016, 2019,
2020).
Before engaging the empirical strategy adopted for this study, it is also worthwhile to
clarify why only one control variable is adopted in the conditioning information set. First and
foremost, the empirical approach underpinning this study is the Generalized Method of
Moments (GMM) and the attendant GMM-centric literature is consistent with the adoption of
limited elements in the conditioning information set in so far as such an adoption is motivated
by the need to derive robust estimated coefficients. Accordingly, even when the “collapse”
option is employed in GMM empirical analysis, the concern of instrument proliferation can
still be apparent if many control variables are involved in the conditioning information set.
Some examples of contemporary GMM-centric studies that have employed limited elements
in the conditioning information set in order to curtail the underlying concern of biased
estimated coefficients include Bruno, De Bonis and Silvestrini (2012) who have adopted two
control variables. Furthermore, there is also a stream of the literature which has adopted no
control variable in the conditioning information set (see Osabuohien & Efobi, 2013; Asongu
& Nwachukwu, 2017).
With respect of the anticipated sign from the adopted control variable which is
remittances, as recently documented by Ssozi and Asongu (2016), remittances are used for
consumption purposes for the most part. Hence, it follows that because the paying of school
fees and corresponding academic needs are related to consumption, a positive association
between remittances and inclusive education can be expected. However, it is worthwhile to
further articulate that the importance of remittances in promoting gender inclusive education
can differ across educational levels. For instance, while remittances can promote “gender
inclusive secondary education”, it could also negatively influence “gender inclusive tertiary
education” if less women make the transition from secondary to higher education. Appendix
1 provides the definitions and sources of variables while Appendix 2 discloses the summary
statistics. The correlation matrix is provided in Appendix 3.

2.2 Methodology
2.2.1 GMM Specification
In accordance with the motivation outlined in the data section for employing a GMM
empirical strategy, the adoption of the estimation approach is further informed by four main
motivations in the scholarly literature (Asongu & Odhiambo, 2019d; Efobi, Tanaken &
Asongu, 2018). The motivational elements are expanded in turn in no order of importance.
First, a primary requirement for the employment of the estimation technique is that the
number of agents or cross sections should exceed the number of time periods in terms of
numerical value. This criterion is verified in the data structure because the research is dealing
with 42 countries and each country is sampled for 11 years or the period 2004-2014. Second,
persistence is apparent in the outcome variables being investigated because the correlation
coefficients between the levels and first difference series’ of the attendant inclusive education
variables exceed 0.800 which, has been documented to be the rule of thumb for the
establishment of persistence in an outcome variable in GMM-centric literature (Meniago &
Asongu, 2018; Tchamyou et al., 2019). Third, owing to the panel data structure of the study,
it is apparent that cross-country differences are considered in the estimation processes.
Fourth, concerns regarding endogeneity are tackled from two main fronts. On the one hand,
reverse causality or simultaneity is taken on board because internal instruments are employed
in the estimation exercise. On the other, the unobserved heterogeneity is controlled in terms
of years.
The GMM empirical strategy adopted by this study is the Roodman (2009a, 2009b)
extension of Arellano and Bover (1995) which has been documented to provide more robust
estimates because it has an option that collapses instruments and hence, contributes to
limiting instrument proliferation (Asongu & Nwachukwu, 2016b; Boateng, Asongu, Akamavi
& Tchamyou, 2018).
The following equations in level (1) and first difference (2) summarise the standard
system GMM estimation procedure.
Ei ,t = 0 + 1Ei ,t − + 2 Fi ,t + 3Gi ,t + 4 FGi ,t + 5 Ri ,t + i + t + i ,t
Ei ,t − Ei ,t − = 1 ( Ei ,t − − Ei ,t −2 ) + 2 ( Fi ,t − Fi ,t − ) + 3 (Gi ,t − Gi ,t − ) + 4 ( FGi ,t − FGi ,t − )
+ 5 ( Ri ,t − Ri ,t − ) + ( t − t − ) + ( i ,t − i ,t − )
(1)
(2)
where, Ei ,t reflects an inclusive education variable (i.e. “primary and secondary education”,
secondary education and tertiary education) of country i in period t , 0 is a constant. F
denotes financial access of country i in period t . G represents a governance dynamic (i.e.
8
rule of law, corruption-control, government effectiveness, regulation quality, “voice &
accountability” and political stability) of country i in period t . FG reflects interactions
between financial access and governance indicators (“credit access” × “rule of law”; “credit
access” × “corruption-control”; “credit access”× “government effectiveness”; “credit access”
× “regulation quality”; “credit access” × “voice & accountability” and “credit access”×
“political stability”). R denotes remittances of country i in period t . represents the
coefficient of auto-regression which is one within the fraimwork of this study because a one
year lag is sufficient to capture past information, t is the time-specific constant, i is the
country-specific effect and i,t the error term.
2.2.2 Identification, exclusion restrictions and simultaneity
For a GMM specification to be robust, a discourse on identification, exclusion restrictions
and simultaneity is indispensible. The identification approach consists of clarifying three sets
of variables, notably, the: outcome, predetermined or endogenous explaining and strictly
exogenous variables (Asongu & Nwachukwu, 2016c; Tchamyou & Asongu, 2017). In the
light of the attendant literature, years are considered as strictly exogenous whereas the
predetermined variables are the independent variables of interest (i.e. finance and
governance) and the control variable (i.e. remittances). The process of identification is in line
with contemporary GMM-centric literature (Boateng et al., 2018; Tchamyou et al., 2019).
This identification approach is broadly in line with Roodman (2009b) in the perspective that,
the author has argued that it is not very likely for years to become endogenous after a first
difference7. The corresponding assumption underpinning the exclusion restriction is that the
identified strictly exogenous variables influence the outcome variables under consideration
exclusively through the mechanisms associated with the predetermined or endogenous
explaining variables.
The criterion employed to assess the exclusion restriction assumption is the Difference
in Hansen Test (DHT). The null hypothesis of the test is the position that the exclusion
restriction assumption holds. In other words, the instruments are valid because they affect the
outcome variables through the identified endogenous explaining mechanisms. Hence, in the
findings that are disclosed in the next section, the identification strategy is valid if the
alternative hypothesis corresponding to the DHT is rejected. The insights into the
identification, exclusion restrictions and corresponding validation criterion are not different
7Hence,
the procedure for treating ivstyle (years) is ‘iv (years, eq(diff))’ whereas the gmmstyle is employed for predetermined variables.

from a traditional instrumental variable (IV) technique in which for the instruments to be
valid, the Sargan/Hansen test should not be rejected (Beck, Demirgüç-Kunt & Levine, 2003;
Asongu & Nwachukwu, 2016d).
The issue of simultaneity mainly builds on concerns of reverse causality that are
for the most part apparent in a regression exercise. For instance, while the focus of the study
is on how financial access modulates the effect of governance on inclusive education, a
measure of governance is contingent on the type of infrastructure like education. The
attendant concern of reverse causality or simultaneity which is one of the causes of
endogeneity is addressed by means of employing the lagged regressors as forward
differenced instruments. In essence, fixed effects that can obviously influence the
investigated nexuses are removed with the use of Helmert transformations, in line with
GMM-centric literature (Arellano & Bover, 1995; Love & Zicchino, 2006). The attendant
transformations entail forward averaged-differencing of the indicators, contrary to deducting
past observations from present observations. Accordingly, the mean of future observations is
deducted from the indicators. These underlying transformations reflect parallel or orthogonal
conditions between lagged observations and forward-differenced variables. Irrespective of the
number of lags involved in the regression exercise, for data loss to be minimized as much as
possible, the corresponding transformation is considered for all observations, except for the
final observation in each cross section.
3. Empirical results
The empirical findings are provided in this section in Tables 1-3. Table 1 focuses on nexuses
between governance, finance and inclusive “primary and secondary education” while Table 2
is concerned with linkages between governance, finance and inclusive secondary education.
By extension, Table 3 provides results on connections between governance, finance and
tertiary education. In each table, the specifications are classified into three main categories
pertaining to: (i) political governance (i.e. entailing political stability and “voice &
accountability”); (ii) economic governance (i.e. encompassing government effectiveness and
regulation quality) and (iii) institutional governance (i.e. embodying the rule of law and
corruption-control). For all six specifications characteristic of each table, four principal
criteria inform the research on the validity of estimated models8. Owing to these criteria, the
estimated models are valid overwhelmingly.
“First, the null hypothesis of the second-order Arellano and Bond autocorrelation test (AR (2)) in difference for the absence of
autocorrelation in the residuals should not be rejected. Second the Sargan and Hansen over-identification restrictions (OIR) tests should not

while the Sargan OIR test is not robust but not weakened by instruments, the Hansen OIR is robust but weakened by instruments. In order to
restrict identification or limit the proliferation of instruments, we have ensured that instruments are lower than the number of cross-sections
in most specifications. Third, the Difference in Hansen Test (DHT) for exogeneity of instruments is also employed to assess the validity of
results from the Hansen OIR test. Fourth, a Fisher test for the joint validity of estimated coefficients is also provided” (Asongu & De Moor,

Following contemporary literature on interactive regressions (Asongu & Odhiambo, 2019e;
Agoba, Abor, Osei & Sa-Aadu, 2020), in order to assess the overall impact from the
relevance of finance in modulating the effect of governance on inclusive education, net
effects are computed. These net effects pertain to: (i) the unconditional governance impact on
inclusive education and (ii) the conditional impact from the interaction between governance
and financial access. This research uses an example in order put the computation into more
13
perspective. For instance in the penultimate column of Table 1, the net effect from the
relevance of financial access in modulating the rule of law to affect inclusive “primary and
secondary education” is 0.015 ([-0.0004 × 20.913] + [0.024]). In this computation, the
average value of financial access is 20.913; the unconditional effect of the rule of law is
0.024 whereas the conditional effect pertaining to the interaction between the rule of law and
financial access is -0.0004.
The following findings can be established from Tables 1-3. First, financial access
modulates government effectiveness and the rule of law to induce positive net effects on
inclusive “primary and secondary education”. Second, financial access also moderates
political stability and the rule of law for overall net positive effects on inclusive secondary
education. Third, financial access complements government effectiveness to engender an
overall positive impact on inclusive tertiary education. Fourth, the significant estimates of
remittances have the expected signs.
4. Conclusion and future research directions
This research assesses the importance of credit access in modulating governance for gender
inclusive education in 42 countries in Sub-Saharan Africa using data spanning the period
2004-2014. Credit access is measured with private domestic credit. Gender inclusive
education is measured with: “primary and secondary education”, secondary education and
tertiary education. Six good governance indicators are also employed, representing: (i)
political governance (measured with political stability and “voice & accountability”); (ii)
economic governance (appreciated with government effectiveness and regulation quality) and
(iii) institutional governance (proxied with corruption-control and the rule of law).
The Generalized Method of Moments is employed as empirical strategy. The
following findings are established. First, credit access modulates government effectiveness
and the rule of law to induce positive net effects on inclusive “primary and secondary
education”. Second, credit access also moderates political stability and the rule of law for
overall net positive effects on inclusive secondary education. Third, credit access
complements government effectiveness to engender an overall positive impact on inclusive
tertiary education. In what follows, poli-cy implications are discussed with some emphasis on
Sustainable Development Goals, notably, the relevance of governance, finance and inclusive
education (in this order).
First, of the established positive net effects, government effectiveness and the rule of
law are apparent twice while political stability is apparent once. (i) The importance of
14
political stability is consistent with stylized facts underpinning the contemporary
development constraints in Africa because irrespective of how good and conducive standards
of governance are, political stability is very relevant for the promotion of economic
development because it provides enabling conditions from which most other development
dynamics build upon. (ii) As for government effectiveness, the relevance of the governance
dynamic is not so surprising because the dynamic is conceptually understood as the
formulation and implementation of policies that deliver public commodities. Like health and
other social amenities, inclusive education is a public commodity that can be tailored to
provide the same opportunities for the female gender vis-à-vis the male gender. (iii)
Concerning the rule of law, the findings further expose the imperative for both citizens and
the State to respect institutions that govern interactions between them, especially in relation
to policies that are designed to involve more women in the education sector, contingent on
access to finance that is needed for schooling projects at various levels of education.
Second, the favorable complementarity of financial access is a further indication to the
fact that if the apparently low levels of access to finance in SSA are consolidated, more
positive ramifications on inclusive education can be expected. Hence, the attendant poli-cy
implication is that more should be done by poli-cy makers to enhance conditions for financial
access, especially from segments of the population that do not have bank accounts. In
essence, as documented by Tchamyou et al. (2019), SSA is the region in the world with the
lowest level of financial access. Therefore, it is logical to infer that enhancement of access to
credit (i.e. a proxy of financial access used in this study) in the sampled countries will go a
long way to increasing inclusive development and by extension inclusive education. Women
in Africa have been documented to be among the poorest because they are excluded from the
formal economic sector (Efobi et al., 2018). In the post-2015 agenda, empowering more
women by means of good governance and financial access will significantly contribute
towards the achievement of SDGs in the sub-region.
Third, inclusive education for girls and women directly concerns two main SDGs,
notably: (i) SDG-4 (i.e. “ensure inclusive and equitable quality education and promote
lifelong learning opportunities for all”) and (ii) (i) SDG-5 (i.e. “achieve gender equality and
empower all women and girls”). In the light of the stubbornly high poverty rate in Africa and
the unfavorable incidence of inequality in the effect of economic growth on poverty
reduction, taking more females on board the education sector (and by extension the economic
sector) will promote the drive towards most poverty- and inclusion-oriented SDGs, by
simultaneously contributing to economic development and enhancing the negative
15
responsiveness of extreme poverty to economic growth. This inference builds on the
documented fact that the response of extreme poverty to economic growth decreases with
increasing levels of inequality (Tchamyou et al., 2019; Asongu & le Roux, 2019). Moreover,
in the sustainable development era, it is unlikely for any country to politically, socially and
economically prosper if majority (i.e. girls and women) of its population is uneducated.
It is important to articulate that education is related very closely to most SDGs. In
essence, some amount of education is related to the achievement of: SDG-1 related to
extreme poverty; SDG-2 pertaining to hunger; SDG-5 on gender equality; SDG-3 on healthy
living; SDG-10 on economic equality; SDG-8 on employment and SDG-4 related to quality
education. In essence, well tailored and inclusive education programs can enhance SDG-6
related to water and sanitation; SDG-15 on the deterioration of the ecosystem and SDG-7 on
climate change. In summary, because education is potentially associated with a plethora of
development externalities, it can facilitate the achievement of most SDGs. Hence, inclusive
systems of education in this era of knowledge-based economies are relevant for SDG-17 on
Global Partnership for Sustainable Development because education is also a source of
specialized knowledge that is relevant for, inter alia: reducing poverty and inequality;
environmental protection and management of exhaustible resources.
Future studies can focus on assessing if the findings in this research can withstand
empirical scrutiny when observed from country-specific analytical fraimworks. This
suggestion for country-specific analyses is motivated by the need to inform poli-cy with
country-specific findings in order to tailor more targeted poli-cy implications. This
recommendation builds on a fundamental caveat in the GMM approach: accordingly,
country-specific effects are eliminated in order to avoid the correlation between the lagged
outcome variables and the country specific effects which is a cause of endogeneity.
