Inability to acquire formal creditbeen often argued as a crucial constraint in expandingduction, which largely restrains farmers from improv-ing conditions in China (e.g., Gale and Collender, 2006;999). The lending terms and conditions set by formaltitutions usually exclude the poor farmerswho farmonured lands and possess little tangible assets that can bellateral for formal loans. As analternative, poor farmersormal loans to meet their consumption or productionh are typically offered at higher interest rates. How-

    adopt microcredit mechanism to deliver credit at reasonable coststo rural people. Microcredit was introduced into China in the mid-1990s as part of the governments poverty alleviation strategies inthe mid-1990s, attempting to ameliorate rural poverty through anancially sustainable approach. Various organisations have beeninvolved in the delivery of microcredit service in China, includingnon-governmental organisations (NGOs), governmental agencies,and rural nancial institutions such as the Rural Credit Cooperative(RCC).2 Since implementing microcredit programmes in 2000, theRCC has expanded its microcredit activity with an extensive net-work in rural areas and evolved as the largest microcredit providerin China (Du, 2004; Sun, 2003).

    However, unlike other countries such as Bangladesh, where themicrocredits potential in reducing poverty has been thoroughlyexamined (see for example, Khandker, 2005; Morduch, 1998; Pittand Khandker, 1998), few attempts have been made in China totest the efciency ofmicrocredit as a poverty reduction instrument.Studies on Chinas microcredit tend to elaborate the developmentand regulations of microcredit programmes, giving little quanti-tative information on the outcomes of programme participation.

    2 The RCC programme outperforms both the NGO and government programmesin terms of nancial sustainability and programme replicability. For details see Parkand Ren (2001) and Zuo (2001).

    Since the lack of credit is regarded as the crucial constraint inimproving the Chinese rural households livelihoods, it is hypoth-esised that microcredit, which targets the rural households for theextension of credit facilities have a positive impact on householdswelfare such as increasing the households income and/or con-sumption. This paper aims to empirically examine this hypothesisby focusing on the microcredit programme operated by the RCC.The rest of the paper is organised as follows: Section 2 discusses theresearchmeempirical the paper.

    g the impact of microcredit programmes requires com-omes (e.g., household income and consumption) whenparticipates in the programme to the same outcomes

    e does not participate. For example, let wi be a binaryprogrammeparticipation equal one for participationbyi and zero for non-participation. Further let Yi1 denotethe outcome of interest when household i participates

    ramme and Yi0 denote the potential value of the samehen it is in the state of non-participation. Thus the trueimpact on the outcome of household i, representede quantied by the difference between Yi1 and Yi0, as07; Perry and Maloney, 2007):

    problems should be addressed to identify the trueimpact: missing data and unobservability. The miss-

    oblem arises because the same household cannot beboth participation and non-participation states at thend thus the true impact of participation in themicrocre-me on a certain outcome cannot be observed. In otheror the other component of the difference expressed inssing (Heckman, 1997;RosenbaumandRubin, 1983). Tohis problem, group statistics such as the average effectt on the treated (ATT) is adopted to replace the missingividual subject (Heckman, 1997). ATT is the most pop-statistics widely used in impact evaluation literature,sures the extent to which the programme change thea group of participants compared to what they wouldenced in the absence of participation3 (see for example,aloney, 2007; Nguyen, 2007; Nguyen et al., 2007). The

    cal model and estimation strategy

    fare indicators used in this paper include householdme and annual consumption. Household income refersl income earned by all household members, whiches the income from all possible sources, such as agri--agriculture, self-employment, and wages. Householdn in this paper is measured by the sum of food con-nd non-food consumption within a household.of the impact evaluation literature suggests that empir-ssessing microcredits impact must carefully addressias issue, which otherwise would reduce the reliabil-pact estimation. Selection bias in microcredit impact

    arises when the households participation in microcre-me or households receipt of microcredit is relatedred (or unobserved) factors that simultaneously affectes of their credit use but these unobserved factors arely accounted for in the impact assessment. Two mainding to such selection bias are non-random programmewhich is caused by unmeasured village attributes and self-selection into the programme which stems fromhousehold characteristics (for details see Islam, 2007;

    999; Pitt and Khandker, 1998). It can be argued thatwelfare outcomes between borrowing households anding households without accounting for unobservedity (such as unobserved household and village charac-ould produce biased results since it will wrongly ascribehange (improvement or deterioration) in welfare out-he programme impact, which partly arises from thed and unobserved factors.t panel data model to mitigate the potential selection

    impact estimation. The empirical analysis is built uponce-in-difference (DD) method, which is an increasinglyhnique in economics for identifying causal effects ofs or treatments in the absence of pure experimentalD estimation framework requires that the outcomes

    d be observed for two groups over two time periods.up, referred as the borrowing group, consists of house-receive microcredit in the period after the start of the(i.e., post-programme period) but not prior to the ini-e programme (i.e., pre-programme period); the secondd non-borrowing group comprises households who domicrocredit during either period (Athey and Imbens,and et al., 2004).

    The standard DD method can be illustrated by the followingregression equation (Angrist and Krueger, 1999; Meyer, 1995):

    Yit = 0 + 0d2t + 1Pi + Mit + it (4)where Yit is the natural logarithm of household outcome inves-tigated (i.e., household annual income or consumption) forhousehold i at period t; d2t is a time dummy variable equal to 1for t=2 (poperiod); PihouseholdMit is an intcates the prborrowed m(i.e., particitures time igroup; 1 call averagesof interest ming (treatmindependenwith mean
