This study finds crude oil prices (`oil prices') affect market or portfolio expected returns on the NSE only via inducement of changes to risk aversion parameters of the `representative agent' who has exposure to both stock market return volatility risk and oil price risk. I refer to this effect...

We find an asset pricing model which consists of the market portfolio, the market skewness or co-skewness factors, and portfolio idiosyncratic volatility factor best explains portfolio risk-return trade-offs on the Nigerian Stock Exchange (NSE), indicating this model is appropriate for studies...

In this study, we find savings deposits have contributed significantly to the effectiveness of regulation induced consolidation within the banking sector in so far as improvements in banking system structure, output, profitability, and competitiveness are concerned. Specifically, we find savings...

I estimate stochastic frontier models for agricultural productivity using factors that proxy for absolute risk aversion (e.g. loan amounts) and factors that proxy for relative risk aversion (loan pricing or interest rates). Empirical findings show absolute risk aversion ceases to matter for...

We find financing helps make up for deficiencies in farming experience and the absence of crop insurance, such that farmers that have less experience or do not have crop insurance are more likely to adopt productivity enhancing activities. We also find farmers are less likely to spend on output...

I find policies targeted at stabilizing exchange rates within the context of Nigeria's managed floating exchange rate regime have not allowed for direct inflation targeting. In spite of this constraint, which is predicted by and consistent with macroeconomic theory, however, interactions between...

We find an asset pricing model which consists of the market portfolio, the market skewness or co-skewness factors, and portfolio idiosyncratic volatility factor best explains portfolio risk-return trade-offs on the Nigerian Stock Exchange (NSE), and is appropriate to studies of the efficiency of...

I find evidence for persistence in depreciation related currency pressure in the Naira to US$ exchange rate with persistence exacerbated by private sector profitability. The empirical evidence shows the Central Bank of Nigeria (CBN) reins in depreciation pressure induced within the private...
