The purpose of this research is to examine the impact of alterations in the path of monetary policy rates on inflation via the supply side of an emerging economy.

The study employed semi-annual data covering the period 2007S1 to 2020S2 on the inflation rate, the combined outputs of industry and agriculture, the lending rate, and the monetary policy rate. The vector autoregression model was estimated and counterfactual simulation exercises were conducted.

The study revealed that a move from a higher to a lower monetary policy rate regime resulted in a shift in inflation from a higher to a lower regime. In particular, a 200-basis point reduction in the monetary policy rate over the simulation horizon produces a 1.3% fall in the inflation rate over the same period.

The study has a limitation due to the unavailability of a long-span dataset on all relevant variables. As a result, it is important to exercise caution when interpreting the study's findings. A potential area for further research is to explore how changes in interest rates impact inflation in the real economy by utilising other multiple-variable time series techniques.

It is the opinion of the authors that for inflation in Ghana to move to a lower regime, conscious efforts should be made by the monetary authorities to gradually move from a regime of a high monetary policy rate to a lower one.

In particular, a 200-basis point reduction in the MPR over the simulation horizon produces a 1.3% fall in the inflation rate over the same period.

This study enhances the authors' knowledge of how monetary policy can affect inflation in developing countries through the supply-side channel.

The quest for economic development has brought adverse effects on the environment through the release of greenhouse gases, such as carbon dioxide (CO₂₎. This will counter the efforts to achieve the Sustainable Development Goals (SDGs) by 2030. This study, therefore, investigates the effect of electricity consumption and urbanization on CO₂ emissions in Ghana. Electricity consumption and urbanization are among the factors that can be used to reduce CO₂ emissions.

Following the STIRPAT framework with the Hansen (2000) least squares threshold estimation strategy, the study employed annual time series data from 1971 to 2019.

The study revealed a single threshold effect of both electricity consumption and urbanization on CO₂ emissions. Electricity consumption intensity reduces CO₂ emission when electricity consumption is below the threshold (6287GWh) but increases when consumption passes the threshold. However, urbanization exerts a positive influence on CO₂ emissions regardless the level of urbanization (either before or after the threshold point). Again, the empirical results revealed that the urbanization threshold moderates the effect of electricity consumption on CO₂ emissions.

Policymakers have to consider redesigning the current urbanization mode to include some new-type urbanization elements.

The threshold effect of electricity consumption and urbanization on CO₂ emissions in Ghana is examined using the Hansen (2000) least square method.

This paper aims to examine whether financial technology is complementing the performance of domestic financial institutions or substituting their performance in Ghana.

The paper used data from the Bank of Ghana Payment System Statistics and Time Series Data of the Bank of Ghana from 2012 to 2021, by using autoregressive distributive lags estimation technique.

The results showed that in both the long run and short run, financial technology has a significant negative impact on bank performance, indicating that fintech serves as substitutes rather than complements for Ghanaian banks. These results suggest that there must be a critical review on the interoperability policy in Ghana and that banks should take advantage of the financial technology to increase profit.

Based on the authors’ study, no empirical work has been extensively done in the Ghanaian context by examining how financial technology serves as either a complement or substitute for domestic banking institutions. This paper focuses on exploring the key definition of financial technology in Ghana and how transactions through these media are affecting or improving the performance of banks.

This study is motivated by the Compact with Africa (CWA) initiative to promote foreign direct investment (FDI) in Africa. However, FDI is argued to be one of the primary causes of environmental pollution (CO2 emissions). In that regard, this study estimates the impact of the CWA initiative on FDI and environmental pollution.

The study utilized the difference-in-difference (DID) and triple difference (DDD) estimation strategies to examine the causal impact of the CWA initiative on FDI and environmental pollution from 2005 to 2019. The study selected nine CWA countries and nine non-CWA countries as treatment and control samples.

The authors found that the CWA initiative positively promotes FDI in the participant countries compared to non-participant countries. The CWA initiative also promoted environmental pollution in the CWA countries compared to non-CWA countries. Furthermore, the DDD estimates show that the effect of the CWA initiative on environmental pollution is through FDI.

The authors recommend policies to attract environmentally friendly FDI for both Compact and non-Compact economies.

The study is the first to provide empirical evidence on the CWA initiative on FDI and environmental pollution in Africa. The study used a quasi-experimental method on the relationship between FDI and environmental pollution in Africa.
