Does Financial Development Reduce the Poverty Gap?

Abstract

Financial development may affect poverty directly and indirectly through its impact on income inequality, economic growth, and financial instability. Previous studies do not consider all these channels simultaneously. To proxy financial development, we use the ratio of private credit to GDP or an IMF composite measure. Our preferred measure for poverty is the poverty gap, i.e. the shortfall from the poverty line. Our fixed effects estimation results for an unbalanced panel of 84 countries over the 1975–2014 period suggest that financial development does not have a direct effect on the poverty gap. However, as financial development leads to greater inequality, which, in turn, results in more poverty, financial development has an indirect effect on poverty through this transmission channel. Only if we use poverty lines of $3.20 or $5.50 (instead of $1.90 a day as in our baseline model) to define the poverty gap, we find that economic growth reduces poverty. This implies that in those cases the overall effect of financial development on poverty may be positive or negative, depending on which indirect effect, i.e. that of income inequality or growth, is stronger. Financial instability does not seem to affect the poverty gap. These results are consistent across various robustness checks.

Does Government Expenditure Affect Regional Inclusive Growth? An Experience of Implementing Village Fund Policy in Indonesia

“…The results of a bivariate causality study in Eastern Indonesia show a high relationship between poverty levels, income distribution, economic growth, and financial inclusion (Erlando et al 2020). The overall effect of financial development on poverty may be positive or negative, depending on the indirect effect the coefficient on income inequality and growth (de Haan et al 2021). On the other hand, financial inclusion harms job opportunities.…”

Foreign direct investment and inclusive green growth in Africa: Energy efficiency contingencies and thresholds

“…Second, we keep tabs on financial development, considering the growing empirical evidence that it can foster IGG in developing countries. For instance, regarding SES, there is a growing consensus that financial development aids poor and vulnerable households to access resources that are essential for investment, growth, poverty alleviation, and inequality reduction (De Haan et al, 2021;Peprah et al, 2019;Asongu & Odhiambo, 2018;Tchamyou et al, 2019). Though Yang et al (2021) report contrary effects, empirical evidence in Weber ( 2014) and Shahbaz et al (2013) also suggest that the relevance of financial development for environmental sustainability goes beyond green finance, innovation, and low greenhouse gas emissions to encompass the provision of resources to address precariousness and stress on the environment.…”

Financial Deepening, Stock Market, Inequality and Poverty: Some African Evidence

“…The two latter studies capture the development of the financial market by looking exclusively at the banking credit to the private sector, which the results are supported by Haan et al (2021). Conversely, Li and Yu (2014), Agnello et al (2012), andJohansson andWang (2014) analyzed financial development using financial reforms or financial repression in both banking and equity markets.…”
