Purpose. Despite the increasing trend of private savings in Nigeria, the country is still characterised by low investment and output growth, thus, suggesting that the average saving rate is still far from being impressive. This study investigates the determinants of private savings in Nigeria.
Methodology. Autoregressive Distributed Lag (ARDL) Model using annual time series data from 1981 to 2016 within the theoretical framework derived from the life-cycle hypothesis is employed in this study. The key variables under investigation are private savings, income, dependency ratio, real interest rate, social security payment, financial development and macroeconomic stability. The data used for analysis are sourced from Central Bank of Nigeria Statistical Bulletin (2016) and World Development Indicator (2016).
Findings. The results show that lifetime income and social security payment have significant positive relationship with private saving in the long-run, while adult dependency has significant negative relationship. In the short-run, adult dependency and social security payment have significant positive relationship with private savings. In addition, the result shows that 62% of deviation from the long-run equilibrium level of private savings is annually corrected for by the model estimated.
Originality. This research investigates both the long-run and short-run effects of the various determinants of private savings in Nigeria. Thus, the study can serve as eye opener to the important variables that can improve the level of private savings in Nigeria.
