Abstract: The paper empirically investigates the degree of bank competition and intermediation efficiency in Ghana. The evidence obtained suggests a non-competitive market structure in the Ghanaian banking system, which hampers financial intermediation. The study also finds that Ghanaian banks are monopolistically competitive. It is argued that the structure, as well as the other markets characteristics, constitutes an indirect barrier to entry thereby shielding the large profits in the Ghanaian banking system. Further, it is argued that policies that encourage and stimulate greater consolidation in the financial sector would go a long way to enhance competition among banks and improve efficiency and profitability.

Abstract This paper examines the role of inequality on the link between governance and economic growth in 44 African countries with data running from 2008 to 2018. Using a system GMM and the generalized least square (GLS) estimators, we establish that the effects of governance on growth are rightly conditioned by inequality. The GMM and GLS estimates portray positive effects of inequality on growth, but only the GMM estimates are significant. For both estimators, the effect of institutions on economic growth is positive and significant. However, inequality retards growth when embedded in selected institutions, which implies a substitution relationship between institutions and inequality on growth. The turning point beyond which inequality begins to contribute negatively to economic growth ranges between 34% and 49% based on the GMM estimates or 40.15% and 44.5% for the GLS analysis depending on the institutional indicator used. Therefore, institutions can only be effective in economic development if income inequality levels of not less than 0.34 and not more than 0.49 are maintained to ensure that inequality does not negate growth. Policy makers of African countries should ensure better income distribution alongside good institutions to achieve sustainable economic growth in the region.

Abstract This paper contributes to the emerging literature on the economic impacts of the Russia–Ukraine war by estimating the effects of that war on FCFA‐denominated sovereign bond yields and spreads for the West African Economic and Monetary Union (WAEMU) countries. Using ordinary least squares regressions on monthly panel data from January 2020 to December 2022, we found three key results. First, the Russia–Ukraine war significantly increased long‐term government bonds but had no impact on short‐term sovereign bond yields. Second, the Russia–Ukraine war raised sovereign bond spreads in WAEMU countries. These results suggest that WAEMU countries may consider reducing sovereign long‐term bond issuances and exploiting alternative financing sources, such as concessional financing, until the war and its corollary of global economic and financial imbalances are resolved. Finally, we found that the Central Bank of West African States's policy rate hikes increase governments' borrowing costs. Given this impact, we recommend complementing monetary policy with nonmonetary and fiscal policy measures to ease inflationary pressure from the Russia–Ukraine war. This approach may help mitigate the upward pressure driven by monetary policy tightening on sovereign borrowing costs in the WAEMU government securities markets.

Abstract Transitioning to renewable energy generates tangible benefits in terms of the environment and emissions of greenhouse gases. However, the economic productivity costs of switching to clean energy cannot be overlooked, in addition to the large resource requirements, potential disruption in energy systems, risks of job losses, and emergence of new inequalities. Therefore, it is crucial to identify and quantify synergies and trade‐offs. This paper investigates the productivity cost of abandoning the use of fossil fuels in African countries, using econometric techniques applied to panel data, including the fully modified ordinary least square. The paper finds that, while renewable energy supply is beneficial to increase total factor productivity, in general, a shift toward a higher share of renewables in the power mix is not without productivity cost on the economy. The analysis accounts for other sources of productivity, such as human capital and the diffusion of embodied technology imported from abroad into local markets. The data also reveal that the energy transition could have heterogeneous effects depending on the regions' and countries' characteristics and stages of transition.

Abstract This paper assesses the impacts of food price increase on households' consumption and welfare in Togo and the efficiency of policy measures, such as cash transfers and food subsidies, implemented by the Togolese government to dampen the adverse impacts. A computable general equilibrium (CGE) model is used given its appropriateness in handling economy‐wide and the welfare effect of specific policies. Simulation results show that an increase in food prices has adversely affected the consumption and welfare of all categories of households. The most affected households are self‐employed in the agriculture and other sectors, seasonal workers, trainees, and housekeepers. However, the study reveals that these adverse effects are mitigated by the government's policy responses, notably through cash transfers and food subsidies. Furthermore, the cash transfer policy seems to have a slightly greater positive effect on household consumption and welfare in response to rising food prices in Togo compared to food subsidies. This indicates that cash transfers mitigated the negative impact of food price increases on the population more effectively than food subsidies policies. These findings offer valuable insights for policymakers in optimizing public interventions and striking a balance between various policy options to address hunger and malnutrition within targeted households in Togo.

Abstract This paper examines the effectiveness of macroprudential regulations in promoting bank stability and the credit market in the Kenyan financial system. The study applies a panel estimation methodology on bank‐level and non‐bank credit data for the period 2001–2021 to achieve its objectives. The study reveals three key findings. First, overall, the banking sector remains resilient as evidenced by the S‐score stability measure. Second, liquidity‐related, capital‐based, and asset‐side macroprudential regulations lower bank stability. Third, there is evidence of dampened bank credit and domestic leakage associated with macroprudential regulations. The paper concludes that macroprudential regulations are ineffective in promoting stability and the credit market. This paper recommends policymakers to use caution when implementing macroprudential conditions. This is to balance out the policy objectives of banking sector stability and access to finance. Additionally, policy makers should be mindful when implementing macroprudential measures that may cause banks to adjust their behavior, leading to domestic credit leakages and cross‐border spillovers.
