Carbon pricing has been recognized not only as the most efficient economic policy instruments to internalize the social cost of emissions, but also as a major tool to generate public revenues that can be used to offset the potential adverse distributional effects of climate policy. However, in many developing countries, there is a widespread reluctance to commit to climate policy, largely due to financial constraints, a lack of public support, and concern over its regressive effects.This paper makes recommendations towards the design of an effective carbon pricing system that not only discourages air pollution but also encourages the gradual uptake of climate-friendly technologies by the private sector in Nigerias oil and gas sector, while supporting public investment in sustainable infrastructures and projects that offset the distributional effect of the climate policy.

This study examines the hedging effectiveness of portfolio investment diversification between developed and developing economies; with focus on the Nigerian stock asset vis--vis the stock assets of the United States (US) and United Kingdom (UK). Its main contribution is in the analysis of optimal portfolio diversification using optimal portfolio weight (OPW) and optimal hedging ratio (OHR). Empirical findings show that the OPW and OHR are low, which indicates impressive potential gains from combining Nigerian stock assets in an investment portfolio with US and UK stock assets. In addition, exchange rate volatility is found to pose stern limitation on the potential benefits of this portfolio diversification arrangement. It is therefore recommended that the monetary authority in Nigeria should pursue policies towards reducing exchange rate volatility to the barest minimum. This will possibly attract more investors from developed economies who might be willing to combine Nigerian stock in their investment portfolio to minimize portfolio risk.
