Impact of household credit on education and healthcare spending by the poor in Peri-Urban areas, Vietnam

There is an ongoing debate about whether microfinance has a positive impact on education

and health for borrowing households in developing countries. To understand this debate,

we use a survey designed to meet the conditions for propensity score matching (PSM) and

examine the impact of household credit on education and healthcare spending by the poor

in peri-urban areas of Ho Chi Minh City, Vietnam. In addition to matching statistically

identical non-borrowers to borrowers, our estimates also control for household pre-treatment

income and assets, which may be associated with unobservable factors affecting both credit

participation and the outcomes of interest. The PSM estimates show a significant and positive

impact of borrowing on education and healthcare spending. However, further investigation of

the effects of the treatment reveals that only formal credit has a significant and positive impact

on education and healthcare spending, while informal credit has an insignificant impact on

spending. This paper contributes to the limited literature on peri-urban areas using evidence

from one of the largest and most dynamic cities in Southeast Asia.

Our estimation strategy, therefore, sought to reduce bias and enhance the reliability of the PSM estimates. Our findings are in line with those of Nguyen (2008) and Quach and Mullineux (2007), who have found that access to credit programmes has a positive impact on household welfare and poverty reduction in rural Vietnam. Spending on education and healthcare affects the formation of human capital. Given their limited physical and financial assets, human capital becomes the most important asset for the poor in peri-urban areas. Therefore, policies aiming at reducing poverty in these areas should consider enhancing subsidized credit to the poor and/or providing subsidized or free universal education and healthcare services. 07.indd 113 3/7/14 9:36:39 AM Journa l o f Southeas t As ian Economies 114 Vo l . 31 , No . 1 , Apr i l 2014 APPENDIXES Appendix 1 Pre-treatment Income per Capita of the Poor and Their Sources of Loans Mean income is VND3.57 million with standard deviation as VND0.844 million, and median of VND3.6 million (see Figure 3).

NOTES The authors thank, without implicating, Andrea Menclova, Asadul Islam and the participants of the Sixth Australasia Development Economics Workshop for their helpful comments and suggestions. Any remaining errors are those of the authors. 1. HCMC has twenty-four districts. District 9 has the fifth lowest population density, with a population of 227,816 (in 2008). 2. The list was provided by the District Department of Labour, Invalids and Social Affairs. Poor households in the list excluded temporary migrants. 3. When we reduced the bandwidth and radius to 0.01 and 0.05 for kernel and radius matching respectively, the results are robust. See Appendixes 2 to 5. 4. Some studies suggest that the estimation should be in the range of 0.1 to 0.9, but there are 44 observations with scores greater than 0.9 (about 11 per cent of the sample); if these are dropped, the estimates will be misleading (Crump et al. 2009). 5. The sets of variables used for estimating scores to draw Figures 1 and 2 are different. Each set of variables should affect both credit participation and outcomes. The impact on education expenditure is featured in Figure 1 and the impact on healthcare expenditure is featured in Figure 2. That is why the two figures are slightly different. 6. Basically, formal credit amounts are larger than informal ones, hence formal credit is considered as consituting a higher level of treatment or a full treatment. We expect that if loans have an effect on outcomes (i.e., education and health care expenditure), borrowing greater amounts will have a stronger impact on the respective outcomes. The mean of accumulated loans per household is VND8,317 thousand (about US$500) and VND15,135 thousand (about US$920) for informal and formal credit, respectively. The average size per loan is VND5,229 thousand (about US$317) and VND9,327 thousand (about US$566) for informal and formal credit, respectively. 7. The impact on both expenditure and school enrolment and/or attendance should be investigated to provide a more complete picture of the effects on education. The impact on child schooling was examined in a separate paper in International Development Planning Review (forthcoming). 8.
