Finance-Inequality Nexus: the long and the short of it

Financial development affects income inequality differently in the short and in the long term. Investigating OECD countries from 1870–2011, we find in the short run, an improvement in financial development tends to reduce inequality, while in the long run, more finance contributes to more inequality. The short‐run effect concurs with theories advocating financial development increases the availability of financial services, primarily for the poor. However, this effect becomes nil within a few years. Results thus imply that policies aimed at reducing inequality through improving access of the poor to finance need to be carefully designed to ensure longevity of impact.
