We document that the unconditional effect of finance on growth is ambiguous. This variation is caused by regional bloc, income level and legal origin differences. Our results suggest that, for financial development (banking sector, insurance sector, stock market) to elicit positive effect on growth, there needs to be an effective institutional framework in place. However, in cases where finance in itself elicits positive effect on growth, further tightening of the institutional framework could be harmful to growth; hence, must be done with caution. Policy implications are discussed.

The interest earning nature of banks comes with the amount of loans that banks are able to advance to their customers. To ensure that the stream of interest is not treacherous, banks must put in place stringent credit risk management practices. In this study, we investigate credit risk and default among Ghanaian banks and how these banks are coping with such pressures. Using a survey method, we found that though varied in nature, all the banks have some form of credit management procedures put in place to manage their loan portfolios. We found loan application processes to be bank specific. However, there are some common requirements that banks usually demand from customers in the process of assessing their suitability for a loan. We also found most of the credit management practices of banks to be consistent with the CAMPARI model. We recommend that the Central Bank facilitate the establishment of a vibrant credit-referencing bureau in order to provide credit history of customers of the banks.

In this study, we re-conceptualize the EKC into a Financial Market Environmental Kuznets Curve (FMECK) that explains the relationship between financial development and sustainability, while introducing institutional quality as a moderator. The study posits that there is an Environmental Kuznets Curve for Africa and that the EKC holds for financial development and sustainability. Institutional Quality and Regulatory framework moderate the financesustainability nexus, which leads to the conceptualization of FMEKC. We find an inverted 'U' relationship between financial development and environmental degradation, which we explain using three arguments. We document that having a robust institutional framework in place could reduce the long-run adverse effects of financial development on the environment.

Design/methodology/approach – Synchronicity is estimated under assumptions of contemporaneous and non-contemporaneous relationship between individual stock returns and the market return. Possible thin-trading effect is also corrected using the Dimson’s Beta approach to estimate synchronicity. In the main empirical model, both the Panel-Corrected Standard Errors and the Generalized Least Square estimations were used to provided robust evidence of governance influencing transparency. Findings – Corporate governance was found to broadly influence the release of firm-specific information in a relatively opaque market through the information environment. However, no evidence in support of the “auditor-reputation effects” theory was found. As well, CEO duality does not create an individual powerful enough to reduce the monitoring role of bo...

Design/methodology/approach Using a sample of 22 Ghanaian banks over the period 2005-2010, the study employs a fixed effect panel model in estimating three different empirical models. Findings The study finds new evidence of bank-specific factors as well as macroeconomic factors determining NPLs. Inflation and industry concentration are not significant in determining NPLs, although both are positively related to NPLs. Practical implications The findings of this study have important implications for policy makers and bank managers. Originality/value The paper offers significant value in shaping and improving the banking sector of emerging markets.
