Description
Purpose – Income inequality stalls economic growth with undesirable socio-economic consequences.
Despite various measures targeted towards reducing the inequality gap, disparities in income distribution
persist in Nigeria. Therefore, this study aims to explore a new line of argument to the finance mechanism in
reducing income inequality.
Design/methodology/approach – The study uses time-series data on Nigeria from 1980 to 2015 with
analysis conducted using the autoregressive distributed lag-error correction model approach of Pesaran et al.
(2001).
Findings – The results show amongst others that the channel of real interest rate on income inequality is
through bank credit, real interest rate has an indirect relationship to income inequality and bank credit has an
equalising impact on income inequality when the model is augmented for a structural break. The results show
amongst others, that, on average, ceteris paribus, a 1% point increase in the real lending interest rate is
associated with a 0.45% decline in the volume of bank credit.
Originality/value – This paper engages a new line of argument by unbundling how financial intermediation
impacts on income inequality. The extant literature submits that finance directly impacts income inequality,
whereas this study investigates further to show that interest rate impacts income inequality through bank credit.
That is, the transmission mechanism by which finance affects income inequality ismodelled and analysed.
