It is against this background that this study investigates the role of migrants’ remittances on financial inclusion in selected SSA countries. Pooled Mean Group (PMG) form of panel ARDL was employed but cross-sectional dependent characteristics of the data required the use of cross-sectional methods that cater for such properties. Consequently, XTDCCE: Dynamic Common Correlated Effects and XTCCE Common Correlated Effects estimator were used as robustness checks. For the purpose of this empirical investigation, we collected data on Remittances, Account Ownership and Income Per Capita for 27 SSA countries based on data availability. The conclusion is that remittances have no significant effect on financial inclusion in SSA. However, the variable demonstrates the potential to positively influence financial inclusion. Thus, there should be concrete policy efforts in the SSA to make remittances count for inclusive growth.

PUBLIC INTEREST STATEMENT Many developing economies especially African countries do not have enough domestic investment to move their economies to the desired level of economic growth and prosperity and thus rely heavily on capital inflows. Remittances serve as a major source of capital inflows for many developing economies both for consumption and investment purposes. Apart from this direct effect, other benefits that have been identified as spillovers of remittances include financial development and inclusions. The two concept borders on size and sophistication of financial services and accessibility of these services to the people. This study basically verified if these benefits (financial development and inclusion) are derivable from remittances in African countries as popularly discussed. However, the outcome of the study does not support the hypothesis that remittances improve financial development and inclusion in African countries. Lukman O. Oyelami Adeyemi A.

Introduction Migration of skilled and unskilled labour from many developing countries to more developed countries has its pros and cons. It is very easy to posit that developing countries are likely to face the shortage of skilled and unskilled labour as a resultof migration. However,the role remittances as a major source of capital inflows in these countries are often not taken into consideration. Thus, a robust discussion of migration should be analysed viz-a-viz with the issue of remittances. The issue of remittances has been widely considered in many global public debates, with scholars such as Gupta, Pattillo, and Wagh (2007), Singh, Haacker, Lee, and Le Goff (2010), Adams and Klobodu (2016), and many others, emphasizing its importance to economic growth and development. Basically, remittances as a construct in this study refer to transfers that are entailed in the Balance of Payments (BOPs) of a country. They comprise transfers by migrants, employees’compensation and private transfers between countries (Awad, 2009).However, informal channels such as postal money orders and private money changers have been identified and these channels comprise up 75%, at least 35% of official transfers among countries (Freund & Spatafora, 2008). Sub-Sahara African (SSA) countries have not been categorised as a significant receipt of remittances. Among the top 25 remittances recipient countries, only Nigeria is in SSA. Nevertheless, there are some countries in the region whose remittance inflow constitutes a larger proportion of their GDP, these include Lesotho—27.3%, Togo—10.1%, Senegal—9 .8%, Cape Verde—9.0%, and The Gambia—8.2%. The issue of under-reporting of remittance in the region is also a big problem. Remittances data are mostly not available, for instance, remittance information are available for less than one-third and two-third of African and SSA countries, respectively; often remittances via informal channels are not captured. However, the region has made substantial progress in terms of remittances inflows over the years. Specifically, the region was estimated to witness 3.4, 3.7 and 3.7 in 2016, 2017 and 2018 respectively in remittance growth rate. In recent times, attention has been given to different channels through which remittances interact with economic growth in developing countries. Some of the channels, as discussed in the literature include household consumption, investment, and national saving, exchange rate and financial development. The nexus between remittances and financial development has been widely discussed in the region compared to other channels. Several extant studies have examined the link by using different measures of financial development. The major conclusion from these studies is that financial development responds positively to remittance inflow. Also, studies in this area usually label remittance as an exogenous factor to domestic variables in developing countries. This assumption may not hold because other domestic variables may have a strong influence on remittances. Take for instance: a strong and viable financial sector in home countries can enable a cheap cost of transfer for the senders. An active financial sector can also make for easy access to funding for the recipient, and this is capable of facilitating increased remittances in such an economy. This draws attention to the causal relationship between remittances and financial development. This in line with Demirgüç-Kunt, Córdova, Peria, and Woodruff (2011) which argued financial sector developments, using aggregate data, is subject to at least some form of endogeneity bias. Oyelami & Ogundipe, Cogent Business & Management (2020), 7: 1712126 https://doi.org/10.1080/23311975.2020.1712126 Page 2 of 15 This study contributes to literature fundamentally by attempting to investigate the causal relationship between financial inclusion and remittances, especially in large SSA countries, and estimate their relationship. In doing this, the study is not unaware of the fact that some studies, such as Toxopeus and Lensink (2007) and Aga and Martinez Peria (2014) have attempted to investigate the connecting links from remittances to financial inclusion at a cross-sectional level in developing countries. This study, however, presents a fresh insight, especially in the way it concentrates on 27 selected SSA countries. This gives room for rigorous and more focused analysis on the nexus between remittances and financial inclusion, and by extension, assessing the extent of the latter in the SSA. In explaining financial inclusion, the study aligned with the definition provided by Beck, Demirguc-Kunt, and Levine (2009)which described “financial inclusionas the availability and equality of opportunities to access financial services”. At this juncture, there is a need to provide distinction and link between financial development which is a popular concept in development economic literature and financial inclusion which is gradually attracting more empirical attention in recent times. According to Demirguc-Kunt, Klapper, and Singer (2017)“financial inclusion implies that all adult members of the society are granted access to a range of proper financial services, designed based on their needs and provided at affordable costs”. Based on this definition, financial inclusion has measured by array of variables including percentage of adults that have an account at a formal financial institution and percentage of adults that had a loan from a financial institution. On the other hand, financial development as defined by Hacıoğlu, Dinçer, and Olgu (2015) is the development in the size, efficiency and stability of and access to the financial system. On the account of this definition, the issue of size, efficiency and stability of the financial system are core issues in financial development while the issue of accessibility is a key in financial inclusion. However, financial inclusion is an integral part of financial development. Beyond this introductory section of the paper, there are four other sections that make up the paper. Section two centres on the discussion of literature from extant studies, section three presents data and methodology. Section four discusses the empirical findings and section five concludes with research contribution and policy implications. 2. Literature review 2.1. Stylized facts of remittances and financial inclusion in Sub-Saharan Africa Following Ratha, Eigen-Zucchi, and Plaza (2016), as shown in figure one, remittance flows to SSA Africa have declined. Specifically, it was estimated to decline by 6.1% and reached $33 billion in 2016. Several factors have been advanced for this nose-diving trend in the flow of remittances into the area. The most important of these factors is the poor economic performances in remittance-sending countries. Many European countries that have absorbed large migrants from the region have not been doing well economically. Another factor, as elucidated in the World Bank 2016 report, is the decline in commodity prices, majorly the price of crude oil. This has a great impact on the countries receiving remittances from regional commodity exporters such as Saudi Arabia. Also, one of the factors is the exchange rate regime in remittance-receiving countries in the region, especially Nigeria. The inconsistency in exchange rate policies, characterized by overregulated exchange regime in many of these countries, has caused the diversion of remittances to informal channels. Moreover, the cost of remittances in SSA has been reported to be very high in caparison with other areas of the world. In the sub-region, the mean remittance costs raised from 9.7% in 2016 Q1 to 9.8% in 2017 Q1 (Ratha et al., 2016). This makes the region the highest in the world. Unfortunately, intraregional remittances transfer corridor was reported to be most expensive in 2017, especially in countries such as Angola and Namibia—27%, South Africa and Botswana—21%, Nigeria and Mali—20%. This makes it extremely difficult to bring the cost of transaction below 3%−5% in the region, as envisaged in the Sustainable Development Goals (SDGs). However, with the increase in oil prices and much improved global economic activities in 2017 and 2018, remittances to the sub-region were estimated to rise by 3.3%. Specifically, remittances to a country like Nigeria, considered being the largest in the region (see Figure 1) are estimated to rise by 1.9%. Also, Ghana, being the second largest is estimated to receive Oyelami & Ogundipe, Cogent Business & Management (2020), 7: 1712126 https://doi.org/10.1080/23311975.2020.1712126 Page 3 of 15 3.1% more, while Senegal occupying the third position is estimated to experience an additional 2.6% in remittance inflows. The array of reports on financial development has shown that SSA and Africa at large have made a substantial improvement in the financial system. However, examining the comparison of private credit to GDP indicates that there is a wide gap with fellow developing economies (World Bank, 2012). According to the same report, private credit to GDP ratio constituted around 24% of GDP in SSA Africa in 2010 this is considered very small compared with 77% for all fellow developing economies, and 172% obtainable in high-income economies. Using the stock market as another indicator of financial development, about 50% of African countries have stock markets and very few of them considered to be liquid (Beck et al., 2009). When the market capitalization of these stock markets is compared with other markets in other regions of the world, market capitalization to GDP is around 38%, excluding South Africa, as against 44% in fellow developing economies and 62% obtainable in high-income economies (World Bank, 2012). Apart from the financial development indicators mentioned above, financial inclusion is gradually becoming another big issue in SSA. Many reports on financial inclusion have shown that the region is not performing well on all inclusion indicators, and this may be one of the reasons for non-inclusive growth in the region. Africa in general, according to Demirguc-Kunt and Klapper (2012) reported that 23% of adults in Africa have an account at a formal financial institution. According to Massara and Mialou (2014)inthe IMF report, the report shows that only 34% of the population has bank accounts in the sub-region, as against 94% in high-income countries. Just 7.3% of the SSA population were reported to use the formal account to receive their salaries. Within SSA, large variation in account ownership has been reported, 42%inSouthernAfricaascomparedto7%inCentral Africa. In 2017, Global Findex data show that within SSA, adults with a financial institution account enjoyed a moderate increase of 4% points since 2014 and mobile money account has risen more than twice precisely 9% points. 2.2. Empirical literature Generally, developing countries are the major beneficiaries of remittances; thus, most works of literature featured here are based on them. Most importantly, the link between remittances vis a vis financial development has been extensively discussed in the literature amidst controversies. Most of the controversies arise from channels through which remittances influence financial development and the direction of causality between the variables. Also, in the reviewed literature, financial development has been measured using different proxies, and this has influenced research outcomes which have made it difficult to achieve a consensus as regards the relationship between remittances and financial development. Studies by Freund and Spatafora (2008) and Giuliano and Ruiz-Arranz (2009), for instance, observed that the remittances can serve as a complement for investment if channelled into Figure 1. Flow of Remittance in SSA countries. Source:International Monetary Fund; World Bank World Development Indicators; staff estimates. Oyelami & Ogundipe, Cogent Business & Management (2020), 7: 1712126 https://doi.org/10.1080/23311975.2020.1712126 Page 4 of 15 productive activities, with high returns when there is a functional financial system. Contrarily, the contribution of remittances may be insignificant, if it fails to ease the liquidity constraints in the financial system which makes it possible to release resources for productive engagements. However, most studies have argued that irrespective of the channel, remittances contribute to financial development and, by extension, economic growth. Likewise, studies by Mundaca (2009), Demirgüç-Kunt et al. (2011) and Rao and Hassan (2011) pointed out that there exists a direct relationship between remittances and financial development. Demirgüç-Kunt et al. (2011) argued in a more specific term that remittances facilitate financial development, due to the positive association that exists between remittances and savings which by extension increases the bank credit. On the same plane, Mundaca (2009) averred that the existence of complementarity between remittances and financial development is a precondition for growth enhancement. This position is also maintained by Nyamongo, Misati, Kipyegon, and Ndirangu (2012) in a similar study using data from Sub-Saharan African. However, a study by Karikari, Mensah, and Harvey (2016) differs markedly in this regard. In taking a different stance, their study focused more on the causal relationship between remittances and financial development in 50 selected African countries. They revealed that certain aspects of financial development are stimulated by remittances, while a better financial system fosters receipts of remittances. Apart from these panel studies, country-specific studies have also demonstrated elements of controversy. The link between remittance inflows and development of the financial sector in Nigeria was examined by Oke, Uadiale, and Okpala (2011). The data employed in the study cover 1977 to 2009. The study revealed that remittance inflows exert a substantial effect on the development of the financial sector. A similar study conducted in Bangladesh by Chowdhurry in 2011 assesses the relevance of remittances to the development of the financial sector. In the study, the link between financial development and remittances was assessed using the cointegration analysis and the vector error correction model. His conclusion is that Bangladesh’s financial system has benefited from the increase in remittance inflows. However, some scholars have expressed reservations about the effect of remittances on financial development. Bettin, Lucchetti, and Zazzaro (2012) employed a behavioural model of household’s remittances to analyse the interaction between remittance and financial development in the home country. The study argued that an inefficient financial sector in the home country may inhibit immigrants’trust to transfer large amounts. With this submission, reversed causality has been established between remittances and financial development. A similar study by Sibindi (2014)examinedthe direction of causality between financial development and remittances, concluding that the causal relationship runs from financial development to remittances without feedback, using data from Lesotho. In recent times, studies are looking at the causal link between remittances and financial development. For example, Chowdhury (2016), using dynamic panel estimation established that remittances can be effective for promoting growth but financial variables. The study submitted that more developed financial systems may attract more remittances. In the same manner, Fromentin (2017)investigated the dynamic interaction between remittances and financial development in Latin America and the Caribbean countries, using Granger causality test and panel non-causality test. The conclusion of the study is that there is a positive and bi-directional link between remittances and financial development. In the same argument, a country-specific study undertaken by Khurshid, Kedong, Călin, and Popovici (2017) shows the causal link between remittances and financial development. Recently, financial inclusion is becoming an important part of financial development; thus, studies are emerging that seem to be interested in the link between remittance and financial inclusion, especially in developing countries. Toxopeus and Lensink (2007) used system equation estimates to examine if when controlled for financial inclusion, whether remittances have a developmental effect in developing countries. The study found evidence supporting the objective. Also, Anzoategui, Demirgüç-Kunt & Martínez Pería (2011) explored the nexus between international remittances and financial inclusion in Oyelami & Ogundipe, Cogent Business & Management (2020), 7: 1712126 https://doi.org/10.1080/23311975.2020.1712126 Page 5 of 15 El Salvador by using aggregate data on bank credit and deposit amounts over the period 1975–2007 for 109 developing countries. They reported evidence of linkage between remittances and financial inclusion. Also, Aga and Martinez Peria (2014) assessed the effect of remittances on financial inclusion in five selected SSA countries (Burkina Faso, Kenya, Nigeria, Senegal and Uganda) comprising about 10,000 households using survey data. They concluded that the chances of a household opening a bank account is largely influenced by international remittances in the five SSA countries. However, Ambrosius & Cuecuecha (2016) in the country-specific study examined the effect of remittances on formal and informal financial services usage using Mexican household data. They submitted that remittances greatly influence the ownership of savings account. 3. Data and methodology To execute empirical analysis for this study, the following data were employed; Adult with bank account per one thousand, credit to the private sector as a percentage of GDP, per capita Remittances and per capita GDP. Financial inclusion as the dependent variable was proxy by an adult with bank account per one thousand. Similarly, the second dependent variable (financial development) was proxy by credit to the private sector as a percentage of GDP. Also, per capita remittances measured by international inflow of remittances is our key independent. Per capita GDP was introduced as the control variable. Additional independent variables were also obtained from the International Monetary Fund (IMF) and the World Development Indicators (WDI) databases which also served sources for all the data. In all, two models were estimated. In the first model, 27 SSA countries were included in a balanced panel analysis. These countries were selected based on data available for the period 1990 to 2016. The countries included comprises Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Comoros, Congo, Dem. Congo Rep., Cote d’Ivoire, Ghana, Guinea, Guinea-Bissau, Kenya, Lesotho, Madagascar, Mali, Namibia, Niger, Nigeria, Rwanda, Sao Tome and Principe, Senegal, Seychelles, Swaziland, Tanzania, Togo and Uganda. The data employed in the second model just like first model ranged from 1990 to 2016. To prevent endogeneity bias in this study, the direction of causality between remittances and financial inclusion was thoroughly investigated using Dumitrescu and Hurlin (2012). The Dumitrescu Hurlin Panel Granger Causality was also used due to the existence of cross-sectional dependence in the data. Subsequently, the relationship among the variables was investigated using Panel ARDL and robustness was also performed, following Chudik and Pesaran (2015) panel estimation that accounts for heterogeneity and cross-sectional dependence in panel data. In addition, the PMG form of panel ARDL was specifically employed due to the short-time nature of data used in this study. 3.1. Specification model Following a similar study in this area, data employed in this study have both cross-sectional and timeseries features. These data were used to study the possible relationship between account opening and independent variables of remittances and GDP per capita in the first model. In the second model, the credit to the private sector serves as dependent variables and remittances and GDP per capita were employed as independent variables. Functionally, the equations estimated can be expressed as follows: ACC ¼FðREMT;GDPÞ(1) CREDIT ¼FðREMT;GDPÞ(2) Pooled Mean Group (PMG) can be formulated as follows: yit ¼∑ p j¼1 λij yi;tjþ∑ q j¼0 δij xi;tjþμiþεit;(3) In equation three, the cross section is represented by i = 1, 2, …… N and time is denoted by = 1,2, …… T. Also, xi;tjdenoted the vector of regressors. While λtand δtare used to represent the parameters of vectors for scalars and external variables with an inherent feature of a group-specific effect.

If these disturbance term co-integrated, then it is an I (0) process. This characteristic suggests that error correction dynamics of the variables in the system moves away from equilibrium, and consequently, equation three can be re-specified to account for error correction thus: Δyt¼ϕiyi;t1þβ0 iXit þ∑ p1 j¼1 λ ij Δyi;tjþ∑ q1 j¼0 δ ijΔxi;tjþμiþεit (4) i= 1,2, ….

The results are presented in table one, two and three below. 3.1.2. Cross-sectional dependence results In line with Pesaran (2004), we investigated the cross-dependence of our data using a battery of cross-dependence tests and the results are reported in Table 1.
