- PublicationAccess to Credit and Agricultural Productivity(AERC, 2026) Achille Barnabé ASSOUTO; Dewanou Jean-Luc HOUNGBEMEAccess to agricultural credit remains a critical challenge in developing countries, limiting the adoption of modern technologies essential for productivity growth. This study investigates the impact of credit access on agricultural productivity among maize producers in Benin, utilizing data from a 2016 survey conducted by the National Agricultural Research Institute of Benin. Employing an endogenous switching regression model, the analysis accounts for selection bias and unobserved heterogeneity. Results indicate that access to credit increases productivity by 40.07% per hectare and 31.97% per FCFA invested. These findings underscore the need for comprehensive policies to enhance agricultural financing and productivity.

- PublicationAgricultural Production Diversity and Market Access: Implications for Dietary Diversity among Smallholder Farm Households in Cameroon(AERC, 2026) Anchang Juliana Adjem; Meliko Majory; Uwem EssiaOvernutrition, overweight, and obesity as consequences of nutrition transition are a growing concern of public policy in less developed countries, where it poses a triple burden even to rural areas battling with undernutrition and micronutrient deficiencies. The complex link between agriculture and nutritional outcomes has been well established. However, studies often overlook key socio-cultural dimensions of nutrition outcomes in the context of the nutrition transition and the increasing triple burden of malnutrition in rural agricultural communities. This study seeks to investigate the implications of agricultural production diversity on dietary diversity in rural smallholder farm households. We hypothesize that in addition to the contribution of production diversity and the mediating role of market access, socio-cultural factors have a significant influence on household dietary diversity and quality. Data was obtained from a cross-sectional survey of smallholder farm households in the Southwest Region, Cameroon, from 2018 to 2019. The effect of agricultural production diversity and better market access was estimated to be positive using both Generalised Poisson regression and Instrumental Variable two Stage Least Square or Instrumental Variable Poisson models. While better market access plays a positive and significant role in nutrition security and diet quality for smallholder farm households, we found that agricultural production diversity has a greater positive effect on diet outcomes than market access. Similarly, households with women empowerment indicators and better knowledge on nutrition were associated with better diet outcomes. We found a greater proportion of households with unfavourable attitudes relating to socio-cultural norms and perception. We posit that agricultural and food policies and investments should adopt an integrated approach that aligns with societal and cultural needs in promoting market access and encouraging more nutritious food choices to effectively and sustainably tackle challenges to poor nutrition. However, longitudinal studies are essential and will provide rigour on the role agricultural production diversity plays in the nutritional and health status of rural households in Cameroon.
- PublicationAnalysis of Gender Differences in Access to Financial Services in Burkina Faso(AERC, 2026) Bouraima Sawadogo; Steve Douanla Meli; Evodie Esther NgomenaThis study analyzes the differences between men and women in terms of access to formal and informal financial services in Burkina Faso. More precisely, using Global Findex (2021) data collected from 1,000 households by the World Bank group, it first attempts, using logistic regressions, to analyze the impact of gender, first on the probability of access to formal financial services, then on the probability of access to formal financial services, of access to informal financial services, and finally on access to both forms of services. Then, using the multivariate decomposition method, it analyzes the gender gaps in access to these two forms of financial services. The results of logistic regressions indicate that compared to men, women are more likely to access not only informal financial services, but also both forms of financial services at the same time. Multivariate decompositions reveal the existence of gaps in access to the two forms of financial services, to the disadvantage of women. These gaps are explained, on the one hand, by differences in characteristics between the two groups, also known as the explained component, particularly standard of living and age, with regard to access to formal financial services, and, on the other hand, by differences in coefficients, also known as the unexplained component, with regard to access to informal financial services.
- PublicationAnalysis of the Impact of Irrigation on the Nutritional Status of Rice Farming Households in the Iffou Region of Côte D'ivoire(AERC, 2026) Allou Nazaire N'DRI; Assi J.C. KIMOUThis paper investigates the impact of irrigation on the nutritional status of rice farming households in M'Bahiakro, which is an irrigated rice-producing area. It utilizes data from a survey of rice farmers conducted by the Ivorian Centre for Economic and Social Research (CIRES) and the International Initiative for Impact Evaluation (3ie). The empirical strategy first estimates a Probit model to determine drivers of participation in the irrigation system. Second, it assesses the impact of irrigation on rice production and rice income using an Endogenous Switching Regression (ESR). Descriptive statistics show that producers participating in the irrigation system have higher productivity levels and higher income compared to non-participant farmers. Similarly, the Household Dietary Diversity Score (HDDS) is higher among households that use irrigation compared to non-participating households. The results of the probit model estimation show that education, training, extension services, off-farm activities, and membership in an agricultural cooperative are the main determinants of participation in irrigation. The results of the impact assessment indicate no significant effect of the irrigation system on food diversity. The impact estimation on rice production and household income shows that participation in the irrigation system has a positive effect on both income and rice production for participants. These findings reveal a positive effect of irrigation on beneficiaries, which implies an interest in the irrigation program for policymakers and rice farmers.
- PublicationArmed conflicts and child nutritional health outcomes: evidence from the Fulani ethnic militia (FEM) conflict in Nigeria(AERC, 2026) Amaka Nnaji; Olukorede Abiona; Omoniyi AlimiIncreasing violent conflict has resulted in population displacement and the destruction of livelihoods, thereby hindering economic growth. This study estimates the association between early exposure to Fulani ethnic militia (FEM) conflicts and subsequent child health outcomes in Nigeria. Using nationally representative Nigerian General Household Survey data merged with georeferenced FEM conflict data, the study shows that contemporaneous exposure to FEM conflict is strongly associated with declining child health – measured in terms of WAZ (short-term measure) or HAZ (long-term measure). We also find that in-utero exposure to FEM conflict is weakly associated with declining long-term child health but not with short-term child health. Specifically, this effect is more severe in rural areas compared to urban areas. Furthermore, girls are more affected by contemporaneous FEM conflict exposure in the long-term health outcome, and boys are more susceptible to FEM conflict exposure in the short-term health outcome. Older children are more negatively affected by contemporaneous FEM conflict exposure. Agricultural productivity, food security, and access to sanitary toilet facilities appear to be the primary underlying channels of the estimated effects. Results are robust to including other conflict measures and variations in weather patterns. Findings highlight the need for conflict prevention and peacebuilding efforts to resolve conflicts between farmers and herders
- PublicationAssessing the Impact of Input Subsidies on Agricultural Productivity in Sub-Saharan Africa: Applied Political Economy Analysis(AERC, 2026) Joseph Manzvera; Mark ManyangaThe increasing policy interests and vibrant scholarly debate surrounding the impact of input subsidy programs in Sub-Saharan Africa have inspired a growing literature on how input subsidies affect agricultural productivity. The available empirical evidence provides contrasting views, with one school of thought supporting input subsidies as agricultural productivity catalysts, while another school of thought views input subsidies as agricultural policies that failed to stimulate productivity but instead imposed unsustainable pressure on national fiscal resources. Therefore, understanding the extent to which input subsidies influence agricultural productivity, the prevailing effect, and the drivers behind one effect or the other is a pressing matter to guide policy and practice. As such, this study systematically reviewed existing literature on the subject matter and synthesized the evidence through an applied political economy analysis lens. Concurrently, a meta-analysis was conducted to disentangle the potential determinants of heterogeneity in estimates of the impact of input subsidy programs across different countries. The findings showed that input subsidy programs contributed to boosting agricultural productivity in Sub-Saharan Africa in general. The average pooled effect size of input subsidies on crop value is US$128/ha (p<0.01). However, there exists a significant heterogeneity in the effect of input subsidy programs from one study to the other (Ι 2 = 100%). This underscored the role played by the prevailing political economy landscape and other subsidy-specific characteristics on the effectiveness of input subsidy programs in Sub-Saharan Africa. Input subsidy programs providing input packages with both fertilizer and improved seeds, as well as the use of a voucher system, enhance the effectiveness of input subsidies. The incidences of political patronage in subsidized input distribution, on the other hand, undermine the effectiveness of input subsidies. Contingent upon these findings, it is therefore proposed that input subsidy packages should include both fertilizer and improved seeds rather than fertilizer alone. There is also a need to deliberately incorporate legume crops, both from crop diversity and soil fertility points of view. The use of a voucher system is also encouraged to strengthen transparency and increase logistics efficiency and recipient targeting, while also permitting the timely delivery of subsidized inputs to farmers. To curb political patronage, it is suggested that farmer production return forms be used in input subsidy targeting to identify productive (but resource-constrained) farmers and, as a result, remove the involvement of public officials.
- PublicationBanking Market Structure and Heterogeneous Response of Bank Lending to Monetary Policy: Evidence from Uganda(AERC, 2026) Dorothy NampewoThis paper investigates the heterogeneous response of bank lending following a monetary policy change. The study was conducted in the context of developing countries and is based on dynamic panel error correction methods using quarterly Ugandan bank-level data for the period 2011 - 2019. Results support the presence of heterogeneity in bank lending response to monetary policy changes by bank size and ownership type. Specifically, monetary policy pass-through is weaker in large foreign banks and stronger in smaller Pan-African banks. Moreover, bank lending response to monetary policy is asymmetric, with insignificant effects when the policy rate is falling. Risk, government borrowing, capital, and liquidity at the bank level, competition at the industry level, and inflation at the macro level are some of the factors that explain the response of bank lending to monetary policy.
- PublicationBanks' Exposure to Sovereign Debt and Loans to The Private Sector in WAEMU(AERC, 2026) Djeneba DRAMÉThis paper examines the relationship between banks’ exposure to sovereign debt and their lending to the private sector. To do so, we use hand-collected bank-level data from all West African Economic and Monetary Union (WAEMU) countries over the period 2003-2022. The results show a negative relationship between banks’ exposure to sovereign securities and their loans to the private sector. Our findings are robust to alternative estimation techniques and proxies for loans to the private sector and domestic public debt identification. The heterogeneity analysis uncovers that the effect is more pronounced in middle-income countries (LMICs) than in low-income countries (LICs). Additionally, we document that foreign banks, particularly Pan-African banks, reduce their loans more than domestic banks. However, larger and well-capitalized banks tend to mitigate the effect.
- PublicationBribery And Tax Evasion: Does The Level Of Financial Constraint Matter?(AERC, 2026) Oludele FolarinDomestically mobilised resources in African countries are low, and the current levels are inadequate to finance projects required to achieve sustainable development goals by 2030. One of the ways by which African governments could increase domestically mobilised revenue is by reducing tax evasion. This study examines the effect of bribery and credit constraints on tax evasion (both the incidence and extent) by firms in SSA, using data from the World Bank Enterprise Survey (WBES) for 26 countries. Instrumental Variable (IV) Probit regression estimation technique was employed to determine the effect of bribery on the incidence of tax evasion. The Instrumental Tobit regression estimation technique was employed to estimate the effect of bribery on the extent of tax evasion. The results emanating from this study show that tax evasion is higher among firms that pay bribes. Also, the positive effect of bribery on tax evasion holds across the different levels of credit constraints. However, the effect is higher among firms that are fully credit-constrained. The results also show that countries with more robust institutional qualities, such as government effectiveness, the rule of law and control of corruption, had a lesser positive effect of bribery on tax evasion. The study findings reinforce the idea that low tax revenue in African countries is self-inflicted by government actions, resulting in weak civil services and institutions. Also, the study's findings indicate that improvement in access to finance goes beyond its role in enhancing economic growth and poverty reduction to include discouragement of tax evasion behaviour by economic agents.
- PublicationCereal Trade and Food Security: Empirical Evidence for Sub-Saharan African Countries(AERC, 2025) Zahonogo, Windbeneti ArnaudSustainable Development Goal 2 (SDG2) aims to end world hunger, but Africa is currently not on track to meet this goal. Sub-Saharan Africa is particularly affected, with a significant increase in undernourished people. The issue of food security is, therefore, a pressing concern, and promoting trade has been suggested as one solution. This study examines the impact of cereal import openness on the prevalence of undernourishment in 27 Sub-Saharan African countries for the period 2000 - 2020. Using a two-stage least square instrumental variable (2SLS-IV) estimator, we find that greater cereal import openness is significantly associated with higher levels of undernourishment in sub-Saharan Africa and then increased food insecurity. Our results are robust to alternative food security indicators.
- PublicationConflict Exposure and Human Capital Formation of Children in Selected Sub-Saharan African Countries(AERC, 2025) Sakketa, Tekalign Gutu; Usman, Muhammed A.; Kedir, AbbiViolent conflict in sub-Saharan Africa (SSA) has resulted in population displacement, psychological trauma, and the destruction of livelihoods, which has hindered economic growth. These events have increased in frequency and severity over time in the region. Violent conflict disrupts children’s human capital accumulation through widespread malnutrition and the disruption of social and emotional skills that should have been acquired in early childhood. This study aims to estimate the relationship between early-life exposure to violent conflict and children’s human capital formation (focusing on child health, nutrition, and schooling) in four selected SSA countries since 2003. Using nationally representative Demographic and Health Surveys (DHS) merged with georeferenced conflict data, the study finds that children exposed to violent conflict, measured by the number of fatalities, experience reduced human capital formation, including stunted growth, underweight status, and lower educational outcomes. Specifically, children in households exposed to violent conflict have higher dropout rates (given their enrollment) and experience delays in completing primary school. Furthermore, the impact of conflict on long-term malnutrition is particularly pronounced among young children and those living in rural areas. Limited access to health facilities during or after conflict, disruptions in livelihoods and/or markets that result in deprivations in the dietary intake of children and mothers, and the place of residence appear to be the underlying mechanisms.
- PublicationConflict Exposure and Human Capital Formation of Children in Selected Sub- Saharan African Countries(AERC, 2025-11) Tekalign Gutu Sakketa; Muhammed A.

- PublicationCOVID-19 Shock, Social Protection, and Food Insecurity in Nigeria(AERC, 2026) Pouirkèta Rita NIKIEMA,; Khadijat Busola AMOLEGBE,; Gbêtondji Melaine Armel NONVIDEWe seek to understand the effect of COVID-19 and assess the effects of social protection in mitigating the effects of the COVID-19 shock on household food insecurity status. We employed the World Bank Living Standard Measurement Survey for Nigeria, focusing on the dataset collected before the COVID-19 shock and during the post-COVID-19 phone survey. We employed a difference-in-differences method and used all the individual measures of food insecurity. We also explored the heterogeneous effects of social protection across the gender of the recipient, household location, and wealth status. Our results show that food insecurity is greater in all households after the pandemic shock. We found that social protection is effective at mitigating the effects of the pandemic and that the effect is greater for cash assistance. The mitigating effect is greater among female-headed households, poor households, those in rural areas, and those involved in farming. The findings of this study highlight the necessity of having a well-organized social protection programme. In particular, policies aimed at promoting cash assistance among female-headed households, poor individuals, those in rural areas, and those involved in farming can have important implications for improving the food security of households in Nigeria.
- PublicationCredit Access and Adoption of ICT by Small and Medium Sized Enterprises in Togo(AERC, 2026) Yaovi Innocento Mawuena; Guy Martial Takam Fongang; Guerlais Noël BouopdaThe study aims to analyse the impact of credit access on the adoption of ICT by Small and Medium sized enterprises (SMEs) in Togo. To achieve the objective, the study uses the general enterprises census data collected by the National Institute of Statistics and Economic and Demographic Studies (INSEED) in 2018 and a propensity score matching method. The results globally show that credit access has a positive and significant impact on ICT adoption. Access to credit increases the probability of Togolese SMEs adopting ICT by about 0.032-0.234, 0.025-0.157 and 0.020-0.147 percentage point for computer, internet, and e-business adoption, respectively. Credit access has a positive and significant impact on ICT adoption for all types of enterprises except for medium enterprises. The study therefore suggests increasing access to credit to increase ICT adoption among Togolese SMEs.
- PublicationDecentralization and Household Prosperity in Cameroon(AERC, 2025) Fozao, Pascaline NjungohRelating to the view that centralized governments are likely to be less sensitive to the needs of the local population than decentralized ones, we set out to investigate the impact of the 2010 decentralization on real total expenditures per adult equivalent – a proxy for household economic well-being (HEW). To do this, appeal is made to the pseudo-panel fixed effect model, with the panel constructed using age cohorts from the two most recent Cameroon household consumption surveys, and the unconditional quantile regression model of Firpo et al. (2009). Specifically, we report fixed effects regressions, correcting standard errors for within-prefecture and age-cohort correlations using the Jackknife estimator, at the mean, across colonial experiences, and the unconditional distribution. Results show that the adjusted exposure to the 2010 decentralization was associated significantly with improvements in household economic well-being (HEW) – in the order of 0.274 log points and 0.247 log points in the full and the labor force samples, respectively. A significant and positive responsiveness of HEW to decentralization is also recorded across expenditure percentiles, and the magnitude increases monotonically from the 10th to the 90th percentiles, except the dent seen among the median households. These results are, in essence, robust across samples (labor force, civil law, and common law samples), at the mean and across the distribution of real total expenditures per adult equivalent. More interestingly, the weighted exposure to the 2010 decentralization is more strongly associated with household economic well-being than the unweighted exposure. These findings are transmitted, at least in part, through improved social service delivery and associated labor market opportunities and these channels have important implications for alleviating poverty and curbing rural-urban migration in Cameroon and elsewhere in Africa.
- PublicationDo Non-Classical Measurement Errors Affect the Effects of Farm Input Subsides on Crop Productivity? Evidence from Malawi(AERC, 2026) Martin Limbikani MwaleNon-classical measurement errors produce biased and inconsistent estimates in estimations. Previous studies have examined the effects of farm production on crop productivity without accounting for non-classical measurement errors. Using satellite data, which is free from neo-classical errors, this study sought to establish whether the effects of Malawi’s farm input subsidy on crop productivity are biased. The study compared results generated using satellite yields to those generated using yields reported by farmers through a survey. The study tested the sensitivity of the satellite estimates by changing the possible yields to fertilizer response rates, and the results remained consistent with the main findings. The findings revealed that the effect of farm input subsidies on crop productivity generated through survey data are upward biased. Farmers over-report yields to demonstrate that they are productive and retain their status as subsidy beneficiaries. Studies on farm input subsidies, therefore, need to pay attention to non-classical measurement errors to provide reliable results and policy advice on farm input subsidies. Furthermore, policy on farm input subsidies needs to strengthen the targeting of beneficiaries to evade inclusion and exclusion errors of productive farmers.
- PublicationDoes Trade Facilitation Contribute to Food Security? A Panel Data Analysis in Sub-Saharan Africa(AERC, 2026) Moukaila Mouzamilou TakparaFood insecurity remains a serious and global concern that continues to escalate due to various factors, including the COVID-19 pandemic and the Ukraine crisis, which have exposed structural vulnerabilities of developing economies, particularly in African countries. This paper analyses the contribution of trade facilitation through physical infrastructure, Information and Communication Technology (ICT), business environment as well as border, and transport efficiency to food security in Sub-Saharan Africa (SSA). The analysis uses a sample of 36 SSA countries from 2005 to 2019 and adopts the fixed effects and the two stage least square methods. Results show that improvement in trade facilitation enhances food security in SSA. This effect is evident in the composite food security and in two dimensions (access and utilization) of food security. Similarly, trade facilitation indicators, namely business environment and ICT are the most promising in SSA's fight against food insecurity. Moreover, the results show also that countries with low rural population experienced positive effects of facilitating trade than countries with high rural population. The results highlight the need for improving regulatory environment as well as simplifying and harmonizing trade procedures to enhance food security in SSA.
- PublicationEconomic Analysis of The Adoption of E-Commerce by Businesses in Cameroon(AERC, 2026) Mpabe Bodjongo; Mathieu JuliotThe objective of this article is to identify factors likely to stimulate e-commerce in Cameroon. The analysis focuses on a sample of 145,439 companies from the 2nd General Business Census (INS, 2018). Drawing on the economic literature, the results obtained using the probit model that combines endogeneity bias treatment and selection bias correction, and the Heckman selection bias correction probit model, reveal that increases in company size, the use of mobile money, education levels, and proximity significantly promote the adoption of e-commerce by businesses. At the sectoral level, these results are only verified in the "Trade and transport" and "Construction and other tertiary services" sub-sectors.
- PublicationEconomic Impact Analysis of Morocco’s Integration to Ecowas(AERC, 2025) Dodo, Akakpo AyebiogbonThis study assesses imports, customs revenue, and welfare effects in ECOWAS countries following a free trade agreement with Morocco. Trade agreements are expected to increase the share of Moroccan trading to the detriment of ECOWAS producers and simultaneously lead to a drop in supply through regional production and the slowdown in regional integration. To avoid regional disintegration, ECOWAS countries should monitor sensitive products with the private sector, adapt trade policies favorable to the competitiveness of sectors of the economy with high production capacities, build the capacity of actors to be able to exploit market opportunities and encourage local consumption. The study highlighted a decline in customs revenue in ECOWAS. These negative effects on customs tariffs could set back the process of Morocco's integration into ECOWAS. Welfare losses, due to the large diversion effects generated by trade agreements, would likely be significant for consumers.
