Due to the scarcity of reliable macro data on microfinance, macro-level studies of the impact of microfinance on poverty are rather limited. However, there are a few recent works that investigate the relationship be- tween the macro economy and microfinance activities and/or performance, such as Ahlin, Lin, and Maio (2011), Ahlin and Lin (2006) and Kai and Hamori (2009), among others.

1. INTRODUCTION

Most of the recent studies of the impact of microfinance onpoverty or income have relied on micro-level evidence basedon household data or entrepreneurial data (e.g., Hulme &Mosley, 1996; Imai, Arun, & Annim, 2010a, 2010b; Khand-ker, 2005; Mosley, 2001). Due to the scarcity of reliable macrodata on microfinance, macro-level studies of the impact ofmicrofinance on poverty are rather limited. However, thereare a few recent works that investigate the relationship be-tween the macro economy and microfinance activities and/orperformance, such as Ahlin, Lin, and Maio (2011), Ahlinand Lin (2006) and Kai and Hamori (2009), among others.The thrust of these studies is either to examine the environ-mental context in which microfinance operates, or investigatethe potential effect of microfinance on key macroeconomicvariables, such as gross domestic product or inequality. Thefindings of a significant relationship between operations ofMicrofinance Institutions (MFIs) and the macro economy cor-roborate the recent evidence based on household data setswhich posits that microfinance has a poverty reducing effect(e.g., Gaiha & Nandhi, 2009; Imai et al., 2010a, 2010b;Khandker, 2005).

This study redirects the attention to macro studies given themixed results of microfinance impact studies at the micro levelin recent years. As the separation of causal effects of micro-credit from selection effects is unsatisfactory in many of themicro-level studies, Armendariz and Morduch (2005) pointedto a potential bias arising in the impact of microfinance in

these studies. In view of this, studies that have recentlyemerged have used one of the following three approaches: (i)randomized control trials (Banerjee, Duflo, Glennerster, &Kinnan, 2009; Feigenberg, Field, & Pande, 2010; Karlan &Zinman, 2010); (ii) financial diaries/portfolios of the poor(Collins, Morduch, Rutherford, & Ruthven, 2009) and (iii)use of other variants of quasi-experimental estimation tech-niques such as treatments effect and propensity score matchingin both cross-sectional and panel data setting (Imai et al.,2010a, 2010b). Evidence from such studies remains mixeddue to different microfinance outcome measures and/or differ-ent methodologies adopted by these studies, leading to the per-ception that microfinance is likely to have little impact onpoverty. 1 Our econometric analysis points to robust povertyreducing effects of microfinance, as elaborated below.

1676 WORLD DEVELOPMENT

The challenges for empirical macro studies of microfinanceinclude: (a) identifying an appropriate measure of microfi-nance activities, in terms of “availability” or “intensity”; (b)identifying the effects of “performance,” distinguished from“presence” and “scale” of microfinance on macro indicators;and (c) examining the robustness of coefficient estimates re-lated to microfinance. Building on the small but emerging lit-erature on analyzing the impacts of microfinance from amacro perspective, the present study aims to examine the rela-tionship between MFI’s gross loan portfolio per capita andFGT class of poverty indices. 2 The results would be usefulfor development agencies, governments, and other investors,as there are important implications for microfinance’s poten-tial role in reducing poverty at macro level. Our counterfactualsimulations illustrate the possible effects on aggregate povertyexpected from the decrease in MFIs’ gross loan portfolio percapita, GDP per capita, or domestic credit which may becaused as a consequence of global recession or financial crisis.

Drawing upon econometric estimations of the cross-countrydata—including a panel—we find consistently that a countrywith higher MFIs’ gross loan portfolio per capita tends tohave lower levels of FGT class of poverty indices, which cor-roborates the poverty reducing role of microfinance. It is nota-ble that microfinance loans per capita are negativelyassociated with not only the poverty headcount ratio, but alsowith the poverty gap and squared poverty gap, implying thateven the poorest benefit from them.

The rest of the paper is organized as follows. The next sec-tion provides a brief explanation of the data which the presentstudy draws upon. Econometric specifications are discussed inSection 3. The main results and simulations are given in Sec-tions 4 and 5, respectively. The final section offers concludingobservations.

2. DATA

The present study analyzes the role of microfinance—vol-ume/scale of activities (not performance/quality)—on poverty,using cross-sectional data covering 48 countries in the devel-oping regions for 2007. 3 The cross-sectional data are supple-mented by a two-period (2003 and 2007) panel covering 61countries. 4 This is based on the data generated by Microfi-nance Information Exchange (2010) or MIX and the WorldDevelopment Indicators 2011 (World Bank, 2011). Launchedin 2002, MIX provides industry, country, and regional leveldata on microfinance outreach and financial performance indi-cators. The information marketplace collates reports of (self-reporting) MFIs annually, based on: (i) pre-determined for-mats and reporting standards; (ii) validation of informationreceived with both internal and external cross checking sys-tems; and (iii) standardization of data to facilitate comparison.Interpreting and further processing the data, however, requirea great deal of caution because (i) MIX may not be able tosend questionnaires to all the MFIs in the country—in partic-ular if MFIs are small and recent, (ii) not all the MFIs sur-veyed by MIX respond (sample selection bias), and (iii)“self-reporting” may be a source of measurement errors evenif MIX imposes the careful cross-checking systems and thereliability of the data is ranked by MIX (Ahlin et al., 2011).It is not possible to know the extent of the errors arising fromthese factors, but the MIX data provide the most comprehen-sive and largest data on microfinance activities (Cull, Demi-rguc�-Kunt, & Morduch, 2011) and the data cover a largefraction of microfinance customers worldwide (Cull, Demi-rguc�-Kunt, & Morduch, 2007). 5

To cross-check the potential bias arising from self-selection,the current study estimates variants of econometric modelswith different sub-samples, based on several criteria such as ex-tent of validity of data submitted by MFIs (see Ahlin et al.,2011 for details). We have found that the results are broadlysimilar and consistent irrespective of which sub-samples are in-cluded. Also, we have compared the gross loan portfolio ofMFI per capita (based on the MIX data)—a dependent vari-able in our models—with three variables on microfinanceactivity at country levels available from WDI 2011; (a)branches, microfinance institutions (per 100,000 adults); (b)deposit accounts, microfinance institutions (per 1000 adults);and (c) loan accounts, microfinance institutions (per 1000adults). We have consistently found that a pair-wise correla-tion is positive and significant for all the three variables 6

and hence surmise that the MIX data aggregated at countrylevels represent actual performance of MFIs.

It is noted that relatively few studies have used a measure ofmicrofinance operations (volume/scale) in a country based onthe MIX data. Also, the present study uses the World Bankpoverty estimates, released in 2008 (Chen & Ravallion, 2008;Ravallion, Chen, & Sangraula, 2008). These poverty estimatesare based on the poverty line of US$1.25 (based on PPP—Pur-chasing Power Parity) per day in 2005, and cover a widerrange of countries than the previous estimates (based on apoverty line of $1.08 on 1993 PPP). While there are manystudies based on the latter, those based on the more recentpoverty estimates are still few. 7 Also, as noted earlier, weuse the FGT class of poverty indices.

With a view to measuring microfinance activities in a coun-try, we rely mainly on Gross Loan Portfolio (GLP) (divided bythe total population) given that it measures actual funds dis-bursed to households. Total GLP of MFIs aggregated for eachcountry is adjusted for write-offs and inflation. This is a bench-mark indicator generated by MIX. Standardization of rawdata facilitates meaningful comparison of benchmark indica-tors (MIE, 2010). Other variables in the poverty equation in-clude gross domestic product per capita, domestic credit as ashare of GDP, and regional dummies. 8 While a robust inverserelationship between poverty and GDP per capita is confirmedin extant literature, share of domestic credit in GDP has amore complex role partly because financial development isboth a cause and result of growth. It is, however, plausiblethat when financial development is low there may be a mutu-ally reinforcing relationship between financial developmentand microfinance. Finally, as poverty is conditioned on manyunobservable regional characteristics (e.g., vulnerability tonatural shocks), regional dummies are used.

3. SPECIFICATION OF MODELS AND ESTIMATION

Our analysis is based on the data for 2007 (for cross-sec-tional estimations), and 2003 and 2007 (for panel data estima-tions), not only because extensive and reliable historical dataon microfinance do not exist 9 but also because internationalpoverty estimates are available only for one or two specificyears for most of the countries. 10 As a result, country paneldata of poverty are unbalanced, as shown in Appendix 4.

We apply both OLS (Ordinary Least Squares) and IV(Instrumental Variable) model or 2SLS (Two Stage LeastSquares) to estimate the effect of gross loan portfolio per capi-ta of MFIs on poverty. 2SLS involves two stages: gross loanportfolio per capita of MFIs is estimated by an instrumentalvariable and other covariates in the first stage and in the sec-ond poverty head count ratio is estimated by the predicted

MICROFINANCE AND POVERTY—A MACRO PERSPECTIVE 1677

gross loan portfolio per capita and other covariates. The useof IV is necessary because gross loan portfolio per capita ofmicrofinance is likely to be endogenous in the poverty equa-tion. Here the endogeneity is associated with the bi-casualrelationship between gross loan portfolio per capita and pov-erty levels in a country. This reverse causality from poverty togross loan portfolio per capita may arise, for example, if pov-erty-oriented development partners and governments providemore funds to MFIs located in poorer countries.

Given the difficulty in finding a valid instrument that satis-fies “an exclusion restriction,” that is, correlates with grossloan portfolio per capita but does not have a direct causal ef-fect on poverty, this papers uses two kinds of instrument, costof enforcing contract and a lag of 5-year average of gross loanportfolio weighted by the number of MFIs for each coun-try. 11 The unit of analysis for the econometric analysis iscountry.

In addition to the cross-sectional estimations, we generatepanel data for 2003 and 2007 for all the variables 12 and esti-mate linear panel models. This construction enables us toexamine the robustness of our coefficients as the panel dataestimation takes account of changes of variables over timeand unobservable country or regional-level effects. Our aimis to further examine the hypothesis that higher gross loanportfolio per capita leads to poverty reduction at macro level.

One of the important limitations pointed out by micro-stud-ies is that microfinance or microcredit does not necessarilyreach the poorest of the poor (e.g., Morduch, 1999). To fur-ther investigate this from the macro perspective, we examinethe effects of gross loan portfolio per capita on poverty gap(which measures depth of poverty) and squared poverty gap(which measures severity of poverty).

Figures 1 and 2 describe the patterns and trends in size andoutreach of the microfinance industry using real gross loanportfolio (after adjusting for inflation), number of MFIs andactive borrowers. Figure 1 shows the trend and patterns of realgross loan portfolio for different regions. Overall, the com-pound growth rate of the median gross loan portfolio in-creases for all regions over the period 2005–09. However,there are variations (steep and gentle) in the year-by-year up-ward slopes, while in one instance (Eastern Europe and Cen-tral Asia), a downward trend is observed. In particular, theslope for 2007–08 is either gently increasing or sloping down-wards. An interpretation of the trend over this period will needto take cognizance of the potential adverse effect of the globalfinancial crisis on the microfinance industry. Until 2007, thelargest MFIs were located in Latin America and the Carib-bean (LAC). However, in 2008, MFIs in Middle East andNorth Africa (MENA) experienced a sharp increase in theirgross loan portfolio.

Figure 2 compares the patterns and trends of gross loanportfolio of different regions and shows that over the yearsSouth Asia has experienced a greater and sharp increase inthe number of active borrowers than other regions. First, itmight be argued that by virtue of population size of countriesin this region, MFIs may have reached out to more clients(scale of outreach). Second, the MFIs in South Asia (e.g., Ban-gladesh or India) might have placed more emphasis on in-crease in the scale of outreach (e.g., in terms of number ofclients) or poverty reduction as their central mission thanthose in other regions.

Table 1 provides a summary statistics of the variablesused in the regression analyses. In view of the heterogeneityof the size of MFIs (gross loan portfolio), outreach (numberof active borrowers), and a country’s output per head(GDPPC), it is always prudent to observe the dispersionof the data. Table 1 indicates that the median in some in-stances is about either a hundredth (East Asia and the Pa-cific (EAP)) or a tenth (MENA) of the mean. This suggeststhat the raw data for the mean are likely to be affected byextreme values.

From the perspective of both numbers of active borrowersand MFIs, microfinance activities in SA countries are more in-tense than in the other regions. At the lower end, MFI activ-ities in Sub-Saharan Africa (SSA) countries tend to show thelowest values for the number of active borrowers (as a proxyfor MFI operations). As observed from the trends (Figures 1and 2), variations in these indicators over time and across dif-ferent regions suggest the need to develop a meaningful indexthat pulls together all three variables.

In terms of the macro indicators, SSA is the poorest regionfor both periods irrespective of the measure (incidence, depth,and severity) in question. Over the period 2003–07, both thepoverty headcount and poverty gap showed a decline of about7 and 4 percentage points, respectively. 13 South Asia is anexception as our sample showed that poverty levels rose inthe region over this period. 14 Among the less “worse off”regions, 15 MENA recorded the lowest poverty headcount ra-tio while LAC showed the highest output per head (GDPPC)in both years. The poverty headcount ratio continued to below (2%) in MENA, while it substantially decreased from14.5% to 8.9% in LAC.

The results of multivariate regressions are given in Tables 2–7 and simulation outcomes in Table 8. With a view to examin-ing the hypothesis of a relationship between gross loan portfo-lio per capita and poverty (incidence, depth and severity),eight different cases (i.e., four for cross-sectional regressionsand four for panel data regression) are examined for each pov-erty measure. Four different cases using cross-sectional datafor 2007 are given in Tables 2, 4 and 6 and other four casesare given in Tables 3, 5 and 7, using two-period (2003 and2007) panel data. In Tables 2, 4 and 6, OLS is applied in col-umns (1) and (2) and IV in columns (3) and (4). The estima-tions in columns (1) and (2) are robust (corrected forheteroscedasticity), and examine cases either using GLP percapita with and without regional dummies. In a similar fash-ion, the IV (columns (3) and (4) of Tables 2, 4 and 6) and panel(Tables 3, 5 and 7), respectively, test the poverty reducing ef-fect of GLP per capita hypothesis.

Three measures of the FGT class of poverty indices areused. Thus, Tables 2 and 3 contain all the estimations (OLS,IV, Fixed Effects (FE), and Random Effects (RE)) for the pov-erty headcount ratio; Tables 4 and 5 examine the case for thepoverty gap (depth) and Tables 6 and 7 investigate the severityof poverty (squared gap).

In column (1) of Table 2, all three specifications using thecross-sectional data show that GLP per capita is negativelyand significantly associated with the poverty headcount ratio,which is consistent with our hypothesis that micro loans re-duce poverty. For instance, because MFI loan per capita is de-fined in log, we observe that a 10% increase in MFI loan percapita reduces poverty by about 0.325% in the case of theIV estimation (in column (4) of Table 2). 16 The coefficient esti-

mate of log of gross loan portfolio per capita of MFI is nega-tive and significant at the 5% level in this case. As expected,GDP per capita is negative and shows a 1% statistical signifi-cance irrespective of the specification or the estimation methodchosen. Furthermore, consistent with the finance-poverty liter-ature, we find that the coefficient estimate of share of domesticcredit to GDP is negative and significant in some cases (col-umns (2) and (4) of Table 2).

Columns (2) and (4) explore the potential effect of regionaldummies on incidence of poverty. We observe that loan percapita of MFIs remain statistically significant after the inclu-sion of the regional dummies. Inclusion of regional dummiesin the poverty headcount equation reveals that ECA, withLAC as the reference case, has a significant negative coefficient(at the 1% level in both the OLS and IV cases). Also, SA andSSA dummies are positive in the OLS estimation. This impliesthat SA and SSA have higher poverty headcount levels relativeto LAC. These regression results are consistent with the sum-mary statistics of Table 1 in which both poverty levels andGDPPC show that SA and SSA trail LAC.

Columns (3) and (4) present the IV estimation with the aimof resolving the potential endogeneity of microfinance vari-ables in the poverty headcount equation, that is, gross loanportfolio per capita. As discussed earlier, the endogeneitymay be due to a bi-causal relationship between poverty andgross loan portfolio per capita. In terms of a bi-causal rela-tionship between gross loan portfolio per capita and povertyheadcount, we allude to the fact that investors who are in-clined to poverty reduction might direct their financial re-sources to countries and regions where poverty is high.Appendices 2 and 3 show the correlation matrix and the first

stage IV estimation which offer a justification for the validityof our instruments.

We use two kinds of instrument, that is, cost of enforcingcontract and weighted 5-year lag of average GLP. The formeris intuitively justified on the ground that the decision of micro-finance commercial investors, especially international funders,on whether to invest in a particular country is likely to dependon the extent to which the country has a good institution (e.g.,represented by a low cost of enforcing contracts) that wouldfacilitate economic activities. In this context, the cost ofenforcing contracts is supposed to have a significant and neg-ative correlation with loan per capita of MFIs (see Appendix2). While a direct effect of the cost of enforcing contracts onpoverty might not be strong as most poor households operatein the informal sector, the higher enforcing costs may excludethe poor from the formal sector employment or credit and per-petuate poverty in the long run. In view of this, we also useweighted 5-year lag of average GLP as an additional instru-ment.

It is worth mentioning that we observe a poverty reducingeffect for MFIs’ gross loan per capita when we use only thecost of enforcing contracts as an instrument. However, sincethe weak identification test is significant at only 10% in thiscase, we find the need to augment the instrumentation. Usingboth instruments yields a much higher Kleibergen-Paap rkWald F-statistic (weak identification test), as shown in col-umns 3 and 4 of Table 2. This does not compromise the Sar-gan’s over-identification test as we fail to reject the nullhypothesis that the instruments are valid, that is, uncorrelatedwith the error term. Also, the p-values (0.02 and 0.00) of the

under identification test in columns (3) and (4) of Table 2 al-low us to reject the null hypothesis that the model is underidentified. These specification tests validate IV estimations. 17

Tables 3, 5 and 7 show the results based on panel estima-tions for the poverty headcount ratio, depth, and severity,respectively. In Table 3, the poverty headcount ratio is esti-mated by the same set of explanatory variables. The numberof observation is 99. It is noted that this estimation is basedon unbalanced panel data and thus the results have to be inter-preted with caution (see Appendix 4 for the list of countriesand frequencies of observations). A similar pattern of resultsis observed, that is, gross loan portfolio per capita of microfi-nance institutions is negatively associated with incidence ofpoverty, after controlling for the effects of other covariatesand unobserved heterogeneity.

In Tables 4 and 5, we have replicated both the cross-sec-tional and panel regressions by replacing the poverty head-count ratio with the poverty gap. To avoid cluttering thetext, we summarize the key findings. All four cases in Table4 show significant negative effects of log of gross loan portfolioper capita of MFIs, implying the potential of microfinance inreducing the depth of poverty. The other explanatory variablesshow expected signs too. This hypothesis is further corrobo-rated by the pooled OLS and random effects model in columns(1) and (4) of Table 5. Loan per borrower shows a statisticallysignificant negative effect. Both the Hausman and theta statis-tics favor random effects over fixed effects.

Tables 6 and 7 report the cases where the dependent variableis squared poverty gap. An examination of the poverty gapand squared poverty gap results shows consistent results in

terms of sign and significance for GLP per capita. Also, in thecase of squared poverty gap, the Hausman test favors randomeffects. 18 Broadly, the results imply that GLP per capita ofMFIs benefits not just the poor but also the poorest. Insum, gross loan portfolio per capita of MFIs is negativelyassociated with the incidence, depth, and severity of poverty.

5. SIMULATIONS

That microfinance is impervious to the global recession fol-lowing the financial crisis is debatable. 19 Some have arguedthat the slowdown of the global economy will impact nega-tively on microfinance as MFIs are now more closely linkedto global financial markets than before. So there will be: (i)a funding or liquidity impact, with greater refinancing risksfor MFIs and (ii) an economic impact, with financial perfor-mance affected by lower lending volumes, higher costs of fund-ing, tighter net interest margins, and greater volatility inforeign exchange losses/gains. Magnoni and Powers (2009),for example, point out that, over 2009–10, the sector-widemicrofinance will grow by some $28 billion less than antici-pated before the crisis. Others are more optimistic. For exam-ple, Littlefield and Kneiding (2009) argue that themicrofinance sector will survive the setbacks because of thestrong foundations and vast untapped market of creditworthyclients. The effects on the poor through MFIs are, however,largely anecdotal. An attempt is made below to simulate thelikely effects of the global recession.

In the context of the recent global recession, we examine thepossible slowdown of poverty reduction 20 as a result of con-

traction: (i) in gross loan portfolio per capita of MFIs and(ii) GDP per capita. Table 8 reports the simulation resultson the basis of the IV estimation reported in column (4) of Ta-ble 2. The calculations 21 are premised on the assumption thatthe coefficient estimate of each variable is the same across dif-ferent regions in the regression and thus the simulated effectsof key variables on poverty are also the same. The third andfourth rows of Table 8 show that a fall in GLP per capita ofMFIs and GDP per capita will tend to increase poverty head-count. While this is plausible in view of the comparative con-tribution of MFI in an economy, the poverty increasing effectof 0.167% (or 0.343%) due to the 5% (or 10%) decline in GLPper capita points to the need for sustainable flow of on-lendingfunds. Although the overall rise in poverty is low, it must beemphasized that this is additional to other cumulative effectsof the global slowdown on poverty (investments, for example,continue to be sluggish).

6. CONCLUDING OBSERVATIONS

Recent assessments of impact of microfinance—based lar-gely on randomized trials—have led to questioning of claimsof women’s empowerment and poverty reduction. The so-called “magic” of microfinance has thus come under deepscrutiny and the findings of little or weak impacts are begin-ning to turn the tide against it. The faltering global economyhas also raised serious concerns about the immunity of themicrofinance sector and its potential for poverty reduction.From this perspective, the preceding analysis centered on thehypothesis that microfinance reduces poverty. We carried

out tests using cross-country data for 2007 and a panel for2003 and 2007. Taking account of the endogeneity associatedwith loans per capita from Microfinance Institutions (MFIs),our econometric results consistently confirm that microfinance

loans per capita are significantly and negatively associatedwith poverty, that is, a country with a higher MFIs’ gross loanportfolio per capita tends to have lower poverty after control-ling for the effects of other factors influencing it. The negative

relationship remains unchanged when the poverty headcountratio is replaced by the poverty gap and squared povertygap. These results suggest that microfinance not only reducesthe incidence of poverty but also its depth and severity. Thepanel results further corroborate these findings. Other factorsthat contribute to poverty reduction include GDP per capitaand share of credit in GDP (as a measure of financial develop-ment of an economy). Besides, there are significant regionaleffects.

Our simulations point to worsening of poverty in a mildrecession scenario with small reductions in gross loan portfolio

per capita, GDP per capita, and share of credit in GDP. Thesesimulations are helpful in adding precision to anecdotal evi-dence about how setbacks to MFIs hurt the poor. Indeed, sus-tained flows to MFIs may help avert to some extentaccentuation of poverty as a consequence of the slow and fal-tering recovery of the global economy.

In conclusion, assertions that microfinance is “oversold”and lacks the “magic” associated with it are widely off themark, if not largely mistaken.

NOTES

1. Some have even questioned the impact in terms of poverty reduction,promotion of gender equality, and reduction in child mortality. Indeed aview that microfinance is oversold is gaining credibility (Rosenberg, 2010).

2. The Foster–Greer–Thorbecke (FGT) class of poverty indices is ageneralized measure of poverty in an economy (e.g., a country) and it isdenoted as pa ¼ 1

n

Pqi¼1

z�yiz

� �awhere z is the poverty line (e.g., reflecting

nutritional requirement), yi is the ith lowest income, n is the population inthe economy, and as q is the number of people whose income is below z,and a is a measure of poverty aversion where a larger a gives greateremphasis to the poorest of the poor (Foster, Greer, & Thorbecke 1984).This comprises the headcount ratio when a = 0 (the fraction of thepopulation which lives below the poverty line), the average income povertygap when a = 1 (the population average of the distances between poorpeople’s income and the poverty line or the extent to which a poor fallsbelow the poverty line on average) and the squared poverty gap (P2) indexwhen a = 2 (a distributionally sensitive poverty index as a weighted sumof poverty gaps where the weights are the proportionate poverty gaps)(Foster et al., 1984). The present study focuses on all three poverty indices.

3. See Appendix 1 for the list of the countries.

4. Appendix 4 lists the countries included in the panel data estimations.Because we include the countries only with data in 2003, the panel covers alarger number of countries.

5. Cull et al. (2007) did not provide any direct evidence for this. Theirclaim was based on Honohan (2004) who used the data on MFIs providedby the Microcredit Summit Organization similar to the MIX data andfound that “the largest 30 microfinance firms account . . . for more than90% of the clients served worldwide by the 234 top firms (and hence formore than three-quarters of those served by all of the 2572 firms reportingto the MicrocreditSummit)” (Honohan, 2004, p. 4). Cull et al. then arguedthat “Honohan’s evidence suggests that . . . the banks here (covered by theMIX data) served over half of all microfinance customers worldwide”

(Cull et al., 2007, p. F111, the phrase in brackets added by authors).

6. For instance, the correlation coefficient between loan accounts peradult and aggregated gross loan portfolio per capita is 0.483 andstatistically significant for 2009. This does not change much when weexclude the outliers, such as Bangladesh.

7. Exceptions include Imai et al. (2010a, 2010b).

8. See Table 1 for descriptive statistics of these variables. These will bediscussed in Section 4.

9. MIX data date back to 1994, but not until 2002 most MFIs were notkeen on submitting their records for public use.

10. This is because the construction of international poverty estimateshas to rely on nation-wide household expenditure or income surveys whichare carried out once or twice in a decade for most of the developingcountries.

11. This index passes the statistical validity of a valid instrument as itshows a high correlation with gross loan portfolio and a low correlationwith the poverty headcount ratio (with the coefficient of correlation being0.8 for the former and 0.1 for the latter, respectively).

12. Due to data constraints on the international poverty data, we tookaverages of poverty for the period 2000–03 and 2004–07.

13. Poverty data for the panel were constructed by taking averages for2000–03 and 2004–07. The data are given in Appendix 5.

14. It is noted that an overall increase in poverty in South Asia is due tothe highly unbalanced nature of our panel data of poverty. As shown inAppendix 5, while Bangladesh has two observations, India, Nepal, and SriLanka have only one either for 2003 or 2007. Despite the fall in povertyheadcount for Bangladesh from 57.8% in 2003 to 49.6% in 2007, includingcountries with high poverty (e.g., Nepal—55.1%) in 2007 accounts for thehigher figure in 2007.

15. Most of the countries used in the study are either transitional ordeveloping countries.

16. This is based on the formulae to interpret the coefficient of semi-logspecification (level-log): DY = (b/100)%DX (Wooldridge, 2009, p.46).Note that poverty headcount ratio is defined in percentages.

17. The relationship between GLP per capita and poverty head countratio may be different according to the countries’ income level. We haverepeated the same regressions (OLS and IV) for three income groups ofcountries, that is, “low income,” “lower middle income,” and “uppermiddle income.” Appendix 6 shows the results of IV. It is observed thatthe negative association between GLP per capita and poverty is the largestand most highly significant for low income countries and becomes smallerand statistically insignificant as the income goes up, while it is significantin case of middle income countries as a whole. A similar pattern of resultsis observed in case of OLS and for other measures of poverty.

18. In addition to the Hausman test, we calculate theta (measure of theextent of biasedness of random effects’ model) and we observe values closeto one (greater than 0.75) for each of three estimations. This supports thefact that country/regional effects over time are important and cannot beignored. Use of theta, which is preferred due to the strong finiteassumption underlying the Hausman test, further supports our choice offixed effects model.
