The present study assesses how governance affects information and communication technology (ICT) at the global level contingent on macroeconomic policy factors such as trade, foreign direct investment (FDI), manufacturing value added, and agricultural value added. The study focuses on 183 countries from 2003 to 2021, and the empirical evidence is based on the generalized method of moments (GMM). The following main findings are established. For the full sample, governance unconditionally promotes ICT development, while trade openness (industrial added value) moderates governance to promote (dampen) ICT development. In sub-Saharan Africa, only trade openness effectively moderates governance to induce an overall positive effect on ICT, while in the Middle East and North Africa (MENA) region, all policy variables moderate governance for an overall positive incidence on ICT sector development. The findings for the MENA region are confirmed in the Europe and Central Asia (ECA) region, with the exception of the moderating role of industrial added value, which engenders an overall negative effect. In the East and South Asia and the Pacific (ESAP) countries, one overall positive incidence is apparent in the role of trade openness, while net negative effects are established from the moderating roles of industrial added value and agricultural added value. In the American sub-sample, a positive (negative) net effect is apparent from the role of industrial added value (trade) in moderating the incidence of governance on ICT sector development. Finally, policy implications are discussed.

This study examines the role of environmental taxes and environmentally-related technologies in the link between natural resources and load capacity factor in G10 nations over the period 1994 to 2019. Using robust econometric techniques, the study reveals that natural resources damage environmental quality by mitigating the nations’ load capacity factor while environmental taxes and environmentally-related technologies promote sustainable environment by increasing load capacity factor. The relevance of environmental taxes and environmentally-related technologies in moderating the effect of natural resources on environmental quality is dampened by extant average levels of natural resources rents which are negative. Policy implications are discussed.

Abstract This study assesses the role of mobile money innovations on income inequality and gender inclusion in 42 sub-Saharan African countries from 1980 to 2019 using interactive quantile regressions. It finds that, first, income inequality unconditionally reduces the involvement of women in business and politics. Second, mobile money innovations interact with income inequality to have a positive impact on women in business and politics. Third, the net effects of mobile money innovations on gender inclusion through income inequality are consistently negative. Fourth, as the positive conditional or interactive effects and negative net effects are consistent across the conditional distribution of gender inclusion, thresholds at which mobile money innovations can completely dampen the negative effect of income inequality on gender inclusion are provided. Therefore, policymakers should work toward improving conditions for mobile money innovations. They should also be aware that reducing both income inequality and enhancing mobile money innovations simultaneously leads to more inclusive outcomes in terms of gender inclusion.

This study assesses, from the perspective of financial stability, how business/financial sustainability, moderates the influence of information technology on female economic participation in 49 countries in Sub-Saharan Africa for the period 2008–2018. The empirical evidence is based on Tobit regression, which accounted for the censored nature of the outcome variables. The following important findings were obtained: First, ICT (information and communications technology) dynamics (mobile phone penetration, internet penetration, and fixed broadband subscriptions) are consistently moderated by business sustainability to positively affect female employment. Second, business sustainability scores must exceed certain thresholds before moderating fixed broadband subscriptions to induce favorable overall effects on female employment, female labor force participation, and female unemployment rates. The positive effects on female employment and labor force participation is ascertained by the thresholds of 18.742 and 19.505 Z-scores, respectively and a Z-score of 17.300 for the negative impact on female unemployment. The thresholds that should be exceeded are within policy reach, make economic sense, and are policy-relevant. This study contributes to the extant literature by providing actionable thresholds for business sustainability that can be employed by policy makers such that information technology positively influences female economic inclusion in Sub-Saharan Africa.

Abstract The purpose of this study is to complement extant literature by examining how mobile money innovations can moderate the unfavorable incidence of female unemployment on female doing of business in 44 countries from sub-Saharan Africa for the period 2004 to 2018. The empirical evidence is based on interactive quantile regressions. The employed doing business constraints are the procedures a woman has to go through to start a business and the time for women to set up a business, while the engaged mobile money innovations are: (i) registered mobile money agents (registered mobile money agents per 1000 km2 and registered mobile money agents per 100,000 adults) and (ii) active mobile money agents (active mobile money agents per 1000 km2 and active mobile money agents per 100,000 adults). The hypothesis that mobile money innovation moderates the unfavorable incidence of female unemployment on business constraints is overwhelmingly invalid. The invalidity of the tested hypothesis is clarified, and the policy implications are discussed.

The study assesses how information sharing through mobile phones affects banking system efficiency in Africa with particular emphasis on income levels (middle-income versus low-income countries) and legal origins (English Common law versus French Civil law countries). The focus is on 53 African countries with data for the period 1996-2019, and the empirical evidence is based on Quantile regressions which enable the study to assess the nexus throughout the conditional distribution of banking system efficiency. The following findings are established: (i) mobile phone penetration promotes banking system efficiency in the 25th quantile and the median of banking system efficiency in low-income countries, while for middle-income countries, it is significant exclusively in the bottom quantile (i.e., 10th quantile). (ii) Except for the highest (i.e., 90th) quantile in which the effect of the mobile phone is not significant in English Common law countries, the impact is significant throughout the conditional distribution of banking system efficiency in Common law countries. (iii) As for French Civil law countries, the nexus is only significant in the median and highest (i.e., 90th) quantile of the conditional distribution of banking system efficiency. Policy implications are discussed.

In developing countries, taxation is perceived as a brake on economic growth. Indeed, taxes in most of these countries are not sufficiently adapted to the specificity of the taxpayer and often do not consider the weak administrative capacity of the countries in the region. In this context, reforms have been initiated over the last decade to create tax environments that encourage savings, investment, entrepreneurship, and social innovation. This study provides an overview of research on the effects of taxation on social innovation and the corresponding implications for the achievement of Sustainable Development Goals (SDGs) in developing countries, taking three approaches: thematic, chronological, and methodological. Most studies agree that high taxes in business undermine social innovation and thus the achievement of SDGs, as social innovation is known to be a driver of most SDGs and business the vehicle. The majority of the selected studies used primary data collected from samples whose representativeness with respect to the population concerned (notably businesses) is still not explicitly justified.

Abstract Understanding the role of information communication and technology (ICT) in environmental issues stemming from extensive energy consumption and carbon dioxide emission in the process of economic development is worthwhile both from policy and scholarly fronts. Motivated on this premise, the study contributes to the rising studies associated with the roles of economic growth, institutional quality and information and communication technology (ICT) have on CO2 emission in the framework of the 21st Conference of the Parties (COP21) on climate convention in Paris. Obtaining data from the emerging industrialized seven (E7) economies (China, India, Indonesia, Russia, Mexico, Brazil and Turkey) covering annual frequency from 1995 to 2016 for our analysis achieved significant outcome. From the empirical analysis, economic globalization and renewable energy consumption both reduce CO2 emissions while ICT, institutional quality and fossil fuel contribute to the degradation of the environment. This study affirms the presence of an environmental Kuznets curve (EKC) phenomenon which shows an invented U-shaped curve within the E7 economies. On the causality front, both income and its square have a feedback causal relationship with carbon emissions while economic globalization, institutional quality, ICT and clean energy all have a one-way directional causal relationship with CO2 emissions. Conclusively, the need to reduce environmental degradation activities should be pursued by the blocs such as tree planting activities to mitigate the effect of deforestation. Furthermore, the bloc should shift from the use of fossil-fuel and leverage on ICT to enhance the use of clean energy which is environmentally friendly.

This study examines the hypothesis that foreign aid dilutes the positive role of taxation on political governance. The empirical evidence is based on the Generalised Method of Moments and 53 African countries for the period 1996-2010. For more policy options, the dataset is disaggregated into fundamental characteristics of African development based on income levels, legal origins, natural resources and landlockedness. While the hypothesis is invalid in baseline Africa, low income and English common law countries of the continent, the research cannot conclude on its validity for other fundamental characteristics of development. Policy implications, caveats and directions for future research are discussed.

Given that challenges on the issue of socioeconomic development faced by countries in sub-Saharan Africa (SSA) have been identified as critical to strengthening the inherent link between governance and socioeconomic conditions, this study examines the interconnections between governance and socioeconomic conditions in SSA. With a focus on 25 countries in SSA between 2005 and 2019, we conduct the analysis based on the Panel-Corrected Standard Error and System Generalized Method of Moments estimations and panel causality tests. The results show that SSA does not seem to have the means of effective governance to spur improved socioeconomic conditions. Moreover, the pervasiveness of institutional problems in many countries of SSA has been responsible for the poor socioeconomic conditions in the region. Likewise, governance quality and socioeconomic conditions are found to influence each other. An improvement in socioeconomic conditions could result in better governance quality. On the other hand, governance quality is viewed as a vital ingredient in achieving needed socioeconomic development outcomes. Thus, it is suggested that there is a need for countries in SSA to streamline governing systems toward engendering improved well-being. The introduction and implementation of transformative policies through effective governance are also necessary for ensuring critical structural changes and increasing social service provision. Overall, there should be a proactive identification of ineffective policies and procedures by policymakers to enhance meaningful impacts in the region.

BackgroundHealth workers in low- and middle-income countries are increasingly demanded to collect more and more data to report them to higher levels of the health information system (HIS), in detriment of useful data for clinical and public health decision-making, potentially compromising the quality of their health care provison. In order to support health workers' decision-making, we engaged with partners in Côte d'Ivoire, Mozambique and Nigeria in a research project to conceive, design, produce, implement and test paper-based health information tools: the PHISICC tools. Our aim was to understand the use of PHISICC tools by health workers and to improve them based on their feedback.MethodsThe design Health Facility Laboratories (HF Labs) in Côte d'Ivoire and in Nigeria were set up after months of use of PHISICC tools. Activities were structured in three phases or ‘sprints' of co-creative research. We used a transdisciplinary approach, including anthropology and Human Centered Design (HCD), observations, shadowing, structured interviews and co-creation.ResultsHealth workers appreciated the standardization of the tools across different health care areas, with a common visual language that optimized use. Several design issues were raised, in terms of formats and contents. They strongly appreciated how the PHISICC registers guided their clinical decision-making and how it facilitated tallying and counting for monthly reporting. However, adherence to new procedures was not universal. The co-creation sessions resulted in modifications to the PHISICC tools of out-patient care and postnatal care.DiscussionAlthough health systems and systemic thinking allowed the teams to embrace complexity, it was the HCD approach that actually produced a shift in researchers' mind-set: from HIS as data management tools to HIS as quality of care instruments. HCD allowed navigating the complexity of health systems interventions due to its capacity to operate change: it not only allowed us to understand how the PHISICC tools were used but also how to further improve them. In the absence of (or even with) an analytical health systems framework, HCD approaches can work in real-life situations for the ideation, testing and implementation of interventions to improve health systems and health status outcomes.

Abstract This study investigated the impact of financial sector development on domestic investment in selected countries of the Economic Community of West African States (ECOWAS) for the years 1985–2017. The study employed the augmented mean group procedure, which accounts for country-specific heterogeneity and cross-sectional dependence, and the Granger non-causality test to test for causality in the presence of cross-sectional dependence. The results show that (1) The impact of financial sector development on domestic investment depends on the measure of financial sector development utilised; (2) Domestic credit to the private sector has a positive but insignificant impact on domestic investment in ECOWAS, whereas banking intermediation efficiency (i.e., ability of the banks to transform deposits into credit) and broad money supply negatively and significant influence domestic investment; (3) Cross-country differences exist in the impact of financial sector development on domestic investment in the selected ECOWAS countries; and (4) Domestic credit to the private sector Granger causes domestic investment in ECOWAS. The study recommends careful consideration in the measure of financial development that is utilised as a policy instrument to foster domestic investment. We also highlight the importance of employing country-specific domestic investment policies to avoid blanket policy measures. Domestic credit to the private sector should be given priority when forecasting domestic investment into the future.

Abstract The impacts of public expenditures on economic growth have been revisited in this paper with respect to capital expenditure, recurrent expenditure and the government fiscal expansion in line with support for the budgetary allocations to various sectors in the context of the Nigerian economy. Pesaran’s ARDL approach has been applied to carry out the impact analysis using annual time-series data from 1981 to 2017. Empirical findings support the existence of a level relationship between public spending indicators and economic growth in Nigeria. Incisively, recurrent expenditures of government were found to be significantly impacting on economic growth in a negative way while the positive impacts of public capital expenditures were not significant to economic growth over the period of the study. Further results from the Granger Causality Test reveal that fiscal expansion of the government that is hinged on debt financing is strongly granger causing public expenditures and domestic investment with the latter also Granger causing real growth in the economy. We, therefore, provide some important policy recommendations following the results of the empirical analysis.

Abstract This study assesses the simultaneous openness hypothesis that trade modulates foreign direct investment (FDI) to induce positive net effects on total factor productivity (TFP) dynamics. Twenty-five countries in Sub-Saharan Africa and data for the period 1980 to 2014 are used. The empirical evidence is based on the Generalized Method of Moments. First, trade imports modulate FDI to overwhelmingly induce positive net effects on TFP, real TFP growth, welfare TFP and real welfare TFP. Second, with exceptions on TFP and welfare TFP where net effects are both positive and negative, trade exports modulate FDI to overwhelmingly induce positive net effects on real TFP growth and welfare real TFP. In summary, the tested hypothesis is valid for the most part. Policy implications are discussed.

Abstract This study provides a harmonization framework for common capital flight policies in Africa. It builds on evidence of persistent extreme poverty in the continent to assess how common measures can be adopted by sampled countries on one cause of extreme poverty: capital flight. The dataset is sub-divided into fundamental characteristics of African capital flight based on income levels, legal foundations, natural resources, political stability, regional proximity, and religious domination. The main finding shows that from a projection date of 2010, a feasible timeframe for harmonizing policies is between 2016 and 2023. This timeframe coincides with the beginning of the post-2015 agenda on sustainable development goals.

Abstract This study assesses the role of globalization-fueled regionalization policies on the financial allocation efficiency of four economic and monetary regions in Africa from 1980 to 2008. Banking and financial system efficiency proxies are used as dependent variables and seven bundled and unbundled globalization variables are employed as independent indicators. The bundling is achieved by principal component analysis, while the empirical evidence is based on interactive fixed effects regressions. The findings are as follows. First, financial allocation efficiency is more sensitive to financial openness compared to trade openness and most sensitive to globalization. The relationship between allocation efficiency and globalization-fueled regionalization policies is defined by: (i) a Kuznets or inverted U-shaped curve in the UEMOA and CEMAC zones (evidence of decreasing returns for allocation efficiency from globalization-fueled regionalization) and (ii) a U-shaped relationship overwhelmingly in the COMESA and scantily in the EAC (increasing returns to allocation efficiency due to globalization-fueled regionalization). These relationships are relevant to the specific globalization dynamics within regions. Economic and monetary regions are more prone to surplus liquidity than pure economic regions are. Policy implications and measures for reducing surplus liquidity are also discussed.

Despite major progress in the design of power transformers, the Achilles’ heel remains the insulation system, which is affected by various parameters including moisture, heat, and vibrations. These important machines require extreme reliability to guarantee electricity distribution to end users. In this contribution, a fiber optic sensor (FOS), consisting of a Fabry–Perot cavity made up of two identical fiber Bragg gratings (FBGs), is proposed, to monitor the temperature and vibration of power transformer windings. A phase shifted gratings recoated sensor, with multilayers of polyimide films, is used to monitor the moisture content in oil. The feasibility is investigated using an experimental laboratory transformer model, especially fabricated for this application. The moisture contents are well correlated with those measured by a Karl Fisher titrator, while the values of temperature compare well with those recorded from thermocouples. It is also shown that the sensors can be used to concurrently detect vibration, as assessed by sensitivity to the loading current. The possibility of dynamically measuring humidity, vibrations, and temperatures right next to the winding, appears to be a new insight that was previously unavailable. This approach, with its triple ability, can help to reduce the required number of sensors and therefore simplify the wiring layout.

Applying the conservation of resource resources theory and the self-efficacy theory, this study investigates the relationship between supervisor incivility, self-efficacy, cynicism and the job embeddedness of employees in the hotel industry. The role of self-efficacy, as an important variable that mediates the relationship between the predictor and the criterion variable, is significantly evaluated. A non-probability sampling technique was used to collect 245 questionnaires from frontline employees of five and four-star hotels in Nigeria. The findings reveal that supervisor incivility has a negative effect on self-efficacy and a positive effect on cynicism, and that self-efficacy negatively affects cynicism. There was no significant relationship with job embeddedness in the study. Importantly, the investigation establishes that self-efficacy is a mediating variable between supervisor incivility and cynicism. The study noted the importance of adopting a policy that introduces periodic seminars and professional training for both employees and supervisors, as a means for curbing incivility and cynicism. The study concludes with theoretical and practical implications, leaving room for further investigation

Abstract The study examines the role of governance in modulating the effect of capital flight on industrialisation in Africa. The empirical evidence is based on Generalised Method of Moments and governance is bundled by principal component analysis, namely (i) political governance from political stability and “voice and accountability”; (ii) economic governance from government effectiveness and regulation quality; and (iii) institutional governance from corruption-control and the rule of law. First, governance increases industrialisation whereas capital flight has the opposite effect; and second, governance does not significantly mitigate the negative effect of capital flight on industrialisation. Policy implications are discussed.

Abstract Background Stigma is a multifaceted concept that potentiates Human Immunodeficiency Virus and sexually transmitted infection acquisition and transmission risks among key populations, including men who have sex with men (MSM) and female sex workers (FSW). Despite extensive stigma literature, limited research has characterized the types and sources of stigma reported by key populations in Sub-Saharan Africa. Methods This study leveraged data collected from 1356 MSM and 1383 FSW in Togo and Burkina Faso, recruited via respondent-driven sampling. Participants completed a survey instrument including stigma items developed through systematic reviews and synthesis of existing metrics. Using exploratory factor analysis with promax oblique rotation, 16 items were retained in a stigma metric for MSM and 20 in an FSW stigma metric. To assess the measures’ convergent validity, their correlations with expected variables were examined through bivariate logistic regression models. Results One factor, experienced stigma, included actions that were carried out by multiple types of perpetrators and included being arrested, verbally harassed, blackmailed, physically abused, tortured, or forced to have sex. Other factors were differentiated by source of stigma including healthcare workers, family and friends, or police. Specifically, stigma from healthcare workers loaded on two factors: experienced healthcare stigma included being denied care, not treated well, or gossiped about by healthcare workers and anticipated healthcare stigma included fear of or avoiding seeking healthcare. Stigma from family and friends included feeling excluded from family gatherings, gossiped about by family, or rejected by friends. Stigma from police included being refused police protection and items related to police confiscation of condoms. The Cronbach’s alpha ranged from 0.71–0.82. Median stigma scores, created for each participant by summing the number of affirmative responses to each stigma item, among MSM were highest in Ouagadougou and among FSW were highest in both Ouagadougou and Bobo-Dioulasso. Validation analyses demonstrated higher stigma was generally significantly associated with suicidal ideation, disclosure of involvement in sex work or same-sex practices, and involvement in organizations for MSM or FSW. Conclusions Taken together, these data suggest promising reliability and validity of metrics for measuring stigma affecting MSM and FSW in multiple urban centers across West Africa.

Abstract There is a growing body of evidence that interest rate spreads in Africa are higher for big banks compared to small banks. One concern is that big banks might be using their market power to charge higher lending rates as they become larger, more efficient, and unchallenged. In contrast, several studies found that when bank size increases beyond certain thresholds, diseconomies of scale are introduced that lead to inefficiency. In that case, we also would expect to see widened interest margins. This study examines the connection between bank size and efficiency to understand whether that relationship is influenced by exploitation of market power or economies of scale. Using a panel of 162 African banks for 2001–2011, we analyzed the empirical data using instrumental variables and fixed effects regressions, with overlapping and non-overlapping thresholds for bank size. We found two key results. First, bank size increases bank interest rate margins with an inverted U-shaped nexus. Second, market power and economies of scale do not increase or decrease the interest rate margins significantly. The main policy implication is that interest rate margins cannot be elucidated by either market power or economies of scale. Other implications are discussed.

The study examines nexuses between carbon dioxide (CO 2 ) emissions, renewable energy consumption and inequality in 39 Sub-Saharan African countries for the period 2004–2014. The empirical evidence is based on Quantile regressions. First, in the 25th quantile of the inequality distributions, as long as CO 2 emissions metric tons per capita are kept below 4.700 (4.100), the Gini coefficient (Atkinson index) will not increase. These are avoidable CO 2 emissions thresholds. Second, renewable energy consumption should be complemented with other policies to: (i) reduce the Gini coefficient when renewable energy consumption is at 50.00% of total final energy consumption and (ii) mitigate the Atkinson index when renewable energy consumption is at 62.500% of total final energy consumption in the bottom quantiles of the Atkinson index distribution and at 50.00% of total final energy consumption in the 75th quantile of the Atkinson index distribution. These are renewable energy consumption thresholds for complementary policies. The novelty of this study in the light of extant literature is fundamentally premised on providing policy makers with avoidable thresholds of CO 2 emissions as well as corresponding thresholds of renewable energy consumption for complementary policies, in the nexus between the green economy and inequality.

This study assesses whether improving governance standards affects environmental quality in 44 countries in sub-Saharan Africa for the period 2000–2012. The empirical evidence is based on generalized method of moments. Bundled and unbundled governance dynamics are used, notably: (i) political governance (consisting of political stability and “voice and accountability”); (ii) economic governance (entailing government effectiveness and regulation quality), (iii) institutional governance (represented by the rule of law and corruption-control); and (iv) general governance (encompassing political, economic, and institutional governance dynamics). The following hypotheses are tested: (i) Hypothesis 1 ( improving political governance is negatively related to carbon dioxide (CO 2 ) emissions ); (ii) Hypothesis 2 ( increasing economic governance is negatively related to CO 2 emissions ); and (iii) Hypothesis 3 ( enhancing institutional governance is negatively related to CO 2 emissions ). Results of the tested hypotheses show that the validity of Hypothesis 3 cannot be determined based on the results; Hypothesis 2 is not valid, while Hypothesis 1 is partially not valid. The main policy implication is that governance standards need to be further improved in order for government quality to generate the expected unfavorable effects on CO 2 emissions.

This study investigates the relevance of government quality in moderating the incidence of environmental degradation on inclusive human development in 44 sub-Saharan African countries for the period 2000–2012. Environmental degradation is measured with CO 2 emissions and the governance dynamics include: political stability, voice and accountability, government effectiveness, regulation quality, the rule of law and corruption-control. The empirical evidence is based on the generalised method of moments. Regulation quality modulates CO 2 emissions to exert a net negative effect on inclusive development. Institutional governance (consisting of corruption-control and the rule of law) modulates CO 2 emissions to also exert a net negative effect on inclusive human development. Fortunately, the corresponding interactive effects are positive, which indicates that good governance needs to be enhanced to achieve positive net effects. A policy threshold of institutional governance at which institutional governance completely dampens the unfavourable effect of CO 2 emissions on inclusive human development is established. Other policy implications are discussed.

This study investigates how increasing economic development affects the green economy in terms of CO 2 emissions, using data from 44 countries in the sub-Saharan Africa for the period 2000–2012. The Generalized Method of Moments is used for the empirical analysis. The following main findings are established. First, relative to CO 2 emissions, enhancing economic growth and population growth engenders a U-shaped pattern whereas increasing inclusive human development shows a Kuznets curve. Second, increasing gross domestic product growth beyond 25% of annual growth is unfavorable for a green economy. Third, a population growth rate of above 3.089% (i.e. annual %) has a positive effect of CO 2 emissions. Fourth, an inequality-adjusted human development index of above 0.4969 is beneficial for a green economy because it is associated with a reduction in CO 2 emissions. The established critical masses have policy relevance because they are situated within the policy ranges of adopted economic development dynamics.

Abstract The flow of foreign direct investment (FDI) into a country can benefit both the investing entity and host government. This study employed panel analysis to examine the factors that determine the direction of FDI to the fast-growing BRICS (Brazil, Russia, India, China, and South Africa) and MINT (Mexico, Indonesia, Nigeria, and Turkey) countries. First, we used a pooled time-series cross sectional analysis of data from 2001 to 2011 to estimate and model the determinants of FDI for three samples: BRICS only, MINT only, and BRICS and MINT combined. Then, a fixed effects approach was employed to provide the model for BRICS and MINT combined. The results demonstrate that market size, infrastructure availability, and trade openness play the most significant roles in attracting FDI to BRICS and MINT, while the roles of availability of natural resources and institutional quality are insignificant. To sustain and promote FDI inflow, the governments of BRICS and MINT must ensure that their countries remain attractive for investment by offering a level playing field for investors and political stability. BRICS and MINT governments also need to invest more in their human capital to ensure that their economies can absorb substantial skills and technology spillovers from FDI and promote sustainable long-term economic growth. This study is significant because it contributes to the literature on determinants of FDI by extending the scope of previous studies that often focused on BRICS only.

The objective of this study is to assess governance drivers of FDI in a panel of BRICS and MINT countries for the period 2001-2011. We bundle and unbundle governance determinants using a battery of contemporary and non-contemporary estimation techniques. Our findings reveal the following: Firstly, for both contemporary and non-contemporary specifications, while the majority of our governance determinants of Gross FDI are significant, they are overwhelmingly insignificant for Net FDI. Secondly, the significance of the governance dynamics in increasing order of magnitude are general governance, political governance, economic governance, political stability, regulation quality and government effectiveness. Thirdly, for non-contemporary specifications, the significance of governance variables is as follows in ascending order of magnitude: economic governance, institutional governance, general governance, corruption-control, political governance and political stability. The importance of combining governance indicators is captured by the effects of political governance, economic governance and institutional governance. The results indicate that the simultaneous implementation of the various components of governance clarifies a country’s attractiveness for FDI location. Policy implications are discussed with particular emphasis on the timing of FDI and its targeting.

Advanced technologies and innovation are essential for promoting sustainable food systems (SFSs) because these technologies can be used to answer some of the critical questions needed to transform SFSs and help us better understand global food security and nutrition. The main objective of this study is to address the question of whether technological innovations have an impact on the transformation of SFSs. There are certain innovations including agricultural land utilization, food processing, production systems, improvement in diets according to people’s needs, and management of waste products. This study provides an overview of new technologies and innovations being used with potential to transform SFSs. Applications of emerging technologies in digital agriculture, including the Internet of Things (IoT), artificial intelligence and machine learning, drones, use of new physical systems (e.g., advanced robotics, autonomous vehicles, advanced materials), and gene technology (e.g., biofortified crops, genome-wide selection, genome editing), are discussed in this study. Additionally, we suggest eight action initiatives, which are transforming mindsets, enabling social licensing, changing policies and regulations, designing market incentives, safeguarding against undesirable effects, ensuring stable finance, building trust, and developing transition pathways that can hasten the transition to more SFSs. We conclude that appropriate incentives, regulations, and social permits play a critical role in enhancing the adoption of modern technologies to promote SFSs.

Increasing agricultural production and optimizing inorganic fertilizer (IF) use are imperative for agricultural and environmental sustainability. Mobile phone usage (MPU) has the potential to reduce IF application while ensuring environmental and agricultural sustainability goals. The main objectives of this study were to assess MPU, mobile phone promotion policy, and whether the mediation role of human capital can help reduce IF use. This study used baseline regression analysis and propensity score matching, difference-in-differences (PSM-DID) to assess the impact of MPU on IF usage. However, the two-stage instrumental variables method (IVM) was used to study the effects of mobile phone promotion policy on IF usage. This study used a national dataset from 7987 rural households in Afghanistan to investigate the impacts of MPU and associated promotion policies on IF application. The baseline regression outcomes showed that the MPU significantly reduced IF usage. The evaluation mechanism revealed that mobile phones help reduce IF application by improving the human capital of farmers. Besides, evidence from the DID technique showed that mobile phone promotion policies lowered IF application. These results remained robust after applying the PSM-DID method and two-stage IVM to control endogenous decisions of rural households. This study results imply that enhancing the accessibility of wideband in remote areas, promoting MPU, and increasing investment in information communication technologies (ICTs) infrastructure can help decrease the IF application in agriculture. Thus, the government should invest in remote areas to facilitate access to ICTs, such as having a telephone and access to a cellular and internet network to provide an environment and facility to apply IF effectively. Further, particular policy support must focus on how vulnerable populations access the internet and mobile phone technologies.

Abstract Background The purpose of this study is to investigate how an increase in information-sharing bureaus affects financial access. Methods We employed contemporary and non-contemporary interactive quantile regressions in 53 African countries for the period 2004–2011. Information-sharing bureaus are proxied with public credit registries and private credit offices. Financial development dynamics involving depth (at overall economic and financial system levels), efficiency (at banking and financial system levels), activity (from banking and financial system perspectives), and size are used. Results Two key findings are established. First, the effect of an increase in private credit bureaus is not clearly noticeable on financial access, probably because private credit agencies are still to be established in many countries. Second, an increase in public credit registries for the most part improves financial allocation efficiency and activity (or credit) between the 25th and 75th quartiles. Conclusions As a main policy implication, countries in the top and bottom ends of the financial efficiency and activity distributions are unlikely to benefit from enhanced financial allocation efficiency as a result of an increase in public credit registries.

An April 2015 World Bank report on the Millennium Development Goal poverty target has revealed that extreme poverty has been decreasing in all regions of the world with the exception of Africa. This study extends the implications of Thomas Piketty’s celebrated literature from developed countries to the nexus between developed nations and African countries by building on responses from Rogoff (2014) and Stiglitz (2014), post Washington Consensus paradigms and underpinnings from SolowSwan and Boyce-Fofack-Ndikumana. The central argument presented is that the inequality problem is at the heart of rational asymmetric development between rich and poor countries. Piketty has shown that inequality increases when the return on capital is higher than the growth rate, because the poor cannot catch-up with the rich. We argue that when the return on political economy (or capitalism fuelled illicit capital flight) is higher than the growth rate in African countries, inequality in development increases and Africa may not catch-up with the developed world. As an ideal solution, Piketty has proposed progressive income taxation based on automatic exchange of bank information. The ideal analogy proposed in tackling the spirit of African poverty is a comprehensive commitment to fighting illicit capital flight based on this. Hence, contrary to theoretical underpinnings of exogenous growth models, catch-up may not be so apparent. Implications for the corresponding upward bias in endogenous development and catch-up literature are discussed.

Un homme de 35 ans, VIH-1, sans antécédents médicaux et chirurgicaux particuliers, a été hospitalisé à Abidjan, Côte d'Ivoire, dans un contexte fébrile, toux, dyspnée, douleurs thoraciques et à la radiographie pulmonaire, un déroulement de la crosse de l'aorte une semaine après avoir débuté les antirétroviraux (ARV). Les scanners angiothoraciques réalisés ont mis en évidence une ectasie aortique globale étendue avec thrombus mural. Une échocardiographie transoesophagienne conclut à une dissection aortique, type A de Stanford. Le diagnostic de tuberculose a été confirmé par l'isolation en culture de Mycobacterium Tuberculosis. Huit ans après, le patient est encore vivant, sans intervention chirurgicale et se plaint de douleurs thoraciques intermittentes. Sa pression artérielle est stable et a une insuffisance rénale modérée. Nous rapportons un cas rare de dissection aortique anévrismale chez un adulte infecté par le VIH-1 dans le cadre d'un syndrome de reconstitution immune avec tuberculose pulmonaire.

Background: Temprano ANRS 12136 was a factorial 2 × 2 trial that assessed the benefits of early antiretroviral therapy (ART; ie, in patients who had not reached the CD4 cell count threshold used to recommend starting ART, as per the WHO guidelines that were the standard during the study period) and 6-month isoniazid preventive therapy (IPT) in HIV-infected adults in Côte d'Ivoire. Early ART and IPT were shown to independently reduce the risk of severe morbidity at 30 months. Here, we present the efficacy of IPT in reducing mortality from the long-term follow-up of Temprano. Methods: For Temprano, participants were randomly assigned to four groups (deferred ART, deferred ART plus IPT, early ART, or early ART plus IPT). Participants who completed the trial follow-up were invited to participate in a post-trial phase. The primary post-trial phase endpoint was death, as analysed by the intention-to-treat principle. We used Cox proportional models to compare all-cause mortality between the IPT and no IPT strategies from inclusion in Temprano to the end of the follow-up period. Findings: Between March 18, 2008, and Jan 5, 2015, 2056 patients (mean baseline CD4 count 477 cells per μL) were followed up for 9404 patient-years (Temprano 4757; post-trial phase 4647). The median follow-up time was 4·9 years (IQR 3·3–5·8). 86 deaths were recorded (Temprano 47 deaths; post-trial phase 39 deaths), of which 34 were in patients randomly assigned IPT (6-year probability 4·1%, 95% CI 2·9–5·7) and 52 were in those randomly assigned no IPT (6·9%, 5·1–9·2). The hazard ratio of death in patients who had IPT compared with those who did not have IPT was 0·63 (95% CI, 0·41 to 0·97) after adjusting for the ART strategy (early vs deferred), and 0·61 (0·39–0·94) after adjustment for the ART strategy, baseline CD4 cell count, and other key characteristics. There was no evidence for statistical interaction between IPT and ART (pinteraction=0·77) or between IPT and time (pinteraction=0·94) on mortality. Interpretation: In Côte d'Ivoire, where the incidence of tuberculosis was last reported as 159 per 100 000 people, 6 months of IPT has a durable protective effect in reducing mortality in HIV-infected people, even in people with high CD4 cell counts and who have started ART.

In this paper, we dissect with great acuteness contemporary insufficiencies of the IFS (2008) definition of the financial system and conclude from sound theoretical underpinnings and empirical justifications that the foundation, on which it is based, while solid for developed countries, holds less ground in developing countries. Perhaps one of the deepest empirical hollows in the financial development literature has been the equation of financial depth in the perspective of money supply to liquid liabilities. This equation has put on the margin (and skewed) burgeoning phenomena of mobile banking, knowledge economy (KE), inequality…etc. We conclude that the informal financial sector, a previously missing component in the IFS conception and definition of the financial system can only be marginalized at the cost of misunderstanding recent burgeoning trends in mobile phone penetration, KE and poverty. Hence, the IFS definition has incontrovertibly fought its final dead battle and lost in the face of soaring trends highlighted above. Despite the plethora of econometric and policy-making sins the definition has committed in developing countries through bias estimates and misleading inferences, may its soul RIP.
