This paper is driven by the vast influence oil money have on the current account balance of major oil producing countries in Africa and the role policy measures could play to soften these effects. Dwelling on the nonlinear techniques, two types of Threshold Regression were used to estimate data on 8 African countries from 1995-2019. The results show evidence of nonlinear impacts of oil revenue on the current account balances of the 8 countries. The nature of the impact relies significantly on the levels of the threshold variable. Precisely, the estimated threshold benchmark for financial development was 33.34; below this threshold the sensitivity of current account balance to crude-oil shocks is higher and the probability of policy measures to mitigate the effects is low and, beyond the threshold the sensitivity of current account balance to crude-oil shocks is low and the probability of policy measure to mitigate the effects is higher. The finding suggested among others that crude-oil shocks is not the primary problem of the current account imbalance of oil-exporting countries rather the nature of the domestic economic policy environment.

This study investigates the relationship between the three measures of manufacturing performance [manufacturing production growth rate (MPGR), share of manufacturing in GDP (SMGDP), capacity utilization rate (CUR)] and the variables of financial system stability [exchange rate (EXR), fiscal deficit (FD), lending rate (LR), saving rate (SR), consumer price index (CPI), bank loan to manufacturing sector (BLM)]. The study uses Johansen cointegration and Parsimonious error correction model as the estimation techniques. Findings from the results of the study reveals that there is a long-run relationship between the three measures of manufacturing performance (i.e. MPGR, SMGDP and CUR) and the variables of financial system stability in Nigeria during the period under review. Also, consumer price index (CPI) and lending rate (LR) have negative and significant impacts on manufacturing production growth rate (MPGR) in Nigeria. In addition, fiscal deficit (FD) and lending rate (LR) have significant and negative effect on share of manufacturing in GDP (SMGDP). Lastly, banks loan to manufacturing sector (BLM) has significant negative effect on capacity utilization rate (CUR) while exchange rate (EXR) has positive and significant impact on capacity utilization rate (CUR).

The presence of contradictory theories and unpredictable empirics calls for this paper to survey the outcome of board traits on financial operation of Nigeria banks. Financial performance of a firm is as important as the firm. Yet, very few studies have examined its impact by the board of directors in Nigeria. Data were obtained and perused using descriptive and inferential figures. Findings show that size of board has significant and constructive bearing on business piece. However, board composition takes undesirable significance. Meetings of board and gender failed to show significance. But, board member nationality and firm size show negative and significant effects. We added by exploring impacts of boards on financial performance. We asked firms to increase the size of the board and engage more independent directors and reduce the number of board diligence and size of the firm. The strong plus impact of board size and firm size on financial operations is an interesting result allowing for additional interrogation of why these behaviours.
