This paper explores the influence of corporate governance on the profitability and credit risk of a sample of listed banks in Tunisia. The methodology involves two main steps. Firstly, principal component analysis is employed to construct a novel governance index, assessing the quality of both internal and external bank governance. This index takes into account the degree of compliance and application of directives and laws mandated by the Tunisian Central Bank regarding banking governance. In the second step, panel data analysis is conducted to scrutinize the impact of internal and external governance mechanisms on the profitability and risk of Tunisian banks. The results reveal that as the governance index increases, the profitability of banks improves in terms of return on assets and stock market performance. Additionally, a higher governance index is correlated with a reduction in credit risks, as indicated by lower instances of non-performing loans and an increased rate of coverage for classified debts. To enhance the robustness of our results, we calculate a standard governance score based on existing empirical literature. Furthermore, to account for potential endogeneity, we employ the two-step system generalized method of moments.

This paper examines the asymmetric link between carbon pricing and the comparative advantage in environmental goods exports in South Africa from 1995 to 2021. The non-linear autoregressive distributed lag model is utilized to investigate the effects of both minor and major positive and negative fluctuations in carbon taxes, technological innovation, and energy transition on comparative advantage. The results reveal that carbon taxes have an asymmetric effect on comparative advantage in both the short and long runs, with positive shocks exerting a greater beneficial influence than negative shocks. Specifically, it is found that a 1% reduction in carbon taxes corresponds to a 1.24% decline in the response variable, whereas a 1% increase in carbon taxes is associated with a 2.72% increase in comparative advantage in environmental goods exports, which is twice as large. The study also uncovers evidence of an asymmetric relationship between low-carbon technological innovation and comparative advantage in environmental goods exports. However, strong evidence of a long-run asymmetric linkage between the energy transition and comparative advantage is not established. Nevertheless, it is noteworthy that a positive shift in energy transition is linked with a 0.32% rise in comparative advantage in environmental goods exports, whereas a negative shift in energy transition corresponds to a 0.11% decrease. The practical policy implications are also discussed.
