Aim/purpose – The poor investment climate is one of the reasons advanced for the slow pace of growth in Nigeria; evidenced by the absence or inadequate amount of investible funds in the productive sectors. While the money market in Nigeria provides very limited investment options, the underdevelopment and underutilisation of the Nigerian Stock Market constitute a drawback to the investment climate. However, any economy desiring sustainable development requires a long-term source of fund. Therefore, this study ascertains the perfor-mance of the stock market and investment growth nexus in Nigeria.Design/methodology/approach – The study is based on the neoclassical growth theory with a slight modification in the wake of Levine’s specification (2003), an augmented investment growth relationship was specified. This study utilises the Autoregressive Distributed Lag (ARDL) in establishing the co-integration relation between stock market development and investment growth. Gross capital formation was used as a proxy for investment growth while the stock market indicators are market capitalisation ratio, total value traded ratio and turnover ratio. The study utilises data covering 1981 to 2018, sourced from the Nigerian Stock Exchange annual reports and diverse publication of the Nigerian Bureau of Statistics.Findings – The market capitalisation ratio had a negative impact on gross capital for-mation both in the short run and the long run, but its significance is only evident in the short run. The turnover ratio had a negative and significant impact on investment growth. The total value traded ratio exerted a positive and significant impact on gross capital formation both in the short run and the long run. The coefficient of the error cor-rection term was negative and statistically significant. Research implications/limitations – The total value traded ratio enhanced investment growth in Nigeria. Both market capitalisation and turnover ratio dampen investment growth. The Stock Exchange is not efficient and does not possess the amount of liquidity required to finance long term investment need in Nigeria. Emphasis on measures geared towards increasing efficiency and liquidity should be intensified by the government. Mean-while, the sectorial analysis of the impact of stock exchange movements in Nigeria and the use of other estimation techniques may create room for more robust relationships.Originality/value/contribution – The study directly investigates the capability of the Nigerian stock market in driving investment, both in the short and long run.

Aim/purpose – Low and fluctuating income coupled with epileptic supply of electricity and rising demand for electricity make determinants of electricity consumption an important issue in developing economies such as Nigeria; given that electricity is essential for the development of any economy. This paper, therefore, examines the determinants of electricity consumption in Nigeria with emphasis on income per capita, number of electricity customers, and electricity distribution shortages. Design/methodology/approach – The study is anchored on the Utility Maximising Behaviour of consumers given their level of income. Data were sourced from the Energy Information Administration (EIA) database and World Development Indicator, 2018. An Autoregressive Distributed Lag (ARDL) technique was used in estimating the factors influencing electricity consumption in Nigeria over the period between 1981 and 2017. Findings – The result reveals that the major propellers of electricity consumption in the long-run in Nigeria are per capita income, population per square kilometre, number of electricity customers as well as electricity shortages. The result refutes the hypothesis that electricity consumption increases with the rising level of income. Electricity consumption increased with the increasing number of population in a given area and the number of electricity customers, while electricity shortages distribution has a differential effect in the short run and long run. Research implications/limitations – Lack of reliable household level data capturing per unit price of electricity, and other determinants of electricity consumption in Nigeria implies the analysis is to be carried out on the macro level. A micro-level analysis will be more beneficial in arriving at clearer estimates of demand for electricity in Nigeria. Similarly, there are other factors that influence demand for electricity in Nigeria which are not readily available, hence the need to interpret the result with caveat. Originality/value/contribution – The research focused on the determinants of electrici-ty consumption instead of energy that has been extensively researched. It contributed to the existing literature on the determinants of electricity consumption in Nigeria by in-cluding electricity distribution shortages, number of electricity customers, and population per square kilometre.
