An Example from Islamic Microfinance

Islamic Microfinance
Microfinance Can Alleviate Poverty
Small loans to disadvantaged individuals (or groups).
State of Microfinance: High rates of interest (some reached APR 100%). Receive Subsidies (95% of microfinance institutions,
UNCDF 2005). Primarely rural environments (e.g. Grameen bank and
BRAC in Bangladesh, TriBanco in Brazil, Prodem in Bolivia and FINCA International).
Challenges:Monitoring: Focus on group lending (less appropriate for
urban settings).Lack of tracking individuals + Increasing number of
MFIs.
Islamic Microfinance
Islamic Finance Islamic commercial banking:
Assets exceed $700 billion ($160 billion in 1997). Market growing 10-15% per year (The Economist 4
September 2008). Relatively protected from current economic crisis
(Financial Times Advisor 10 November 2008).
Main principles: Ban on interest + Equitable risk sharing.
Mechanisms: Cost-plus sales (the most widely used). Profit-sharing. Joint venture financing.
Islamic Microfinance
Islamic Microfinance?• Can expand potential clientele. • Increase take-up rates.• Enrich contractual settings.• New field (HSBC currently establishing an Islamic
microfinance project in Pakistan).
• Our project: Experimental investigation of Islamic microfinance
products. Possible field implementation and evaluation.
Islamic Microfinance
Controlled ExperimentsControlled environment to mimic the decisions
of interest (avoid confounds).
Wind-tunnel (Plott 1979).
Induced valuation: paying experimental participants based on their decisions (Smith 1976).
Random assignment (unlike observational data or traditional interventions).
Inexpensive pre-tests.
Islamic Microfinance
Previous Work Group vs. individual lending:
Same repayment rates (Philippines) (Gine and Karlan 2008) (Karlan and Harigaya 2006).
Risk taking (Gine et al. 2006). Group size irrelevant - information central (Carpenter 2002).
Interest rates: Same repayments for consumer microcredit (South Africa)
(Karlan and Zinman 2008). Lower repayment for individuals, higher repayment for groups
(Abbink et al. 2006).
Tracking borrowers: Reduces moral hazard (microfinance) (Gine et al. 2006),
(microcredit) (Karlan and Zinman 2008).
Islamic-compliant contracts – not previously examined experimentally.
Islamic Microfinance
Our SettingEntrepreneurial individual lending.
Focus: moral hazard (vs. adverse selection) (see, e.g., Cason et al. 2008, Cull et al. 2008, De Aghion and Morduch 2005, Gine et al. 2006, and Stiglitz 1990).
Compare ex post moral hazard in interest-based vs. Islamic contracts.
Used to design field experimentation.
Islamic Microfinance
Our ExperimentsGet loan, invest in risky project, learn outcome
(lender does not), pay back or not (moral hazard).
Interest-based (10%) – no risk sharing.
Profit-sharing (80%) – complete risk sharing.
Joint Venture (40%, 60%) – partial risk sharing.
Hypothesis: More default risk sharing does not significantly decrease repayment rates.

Summary of Future WorkEvaluate effectiveness of contractual types in
the lab:Different participants: Students, Muslim students,
disadvantaged Muslims, microfinance clientele.
Design field implementation (Bangladesh).
Choice of contract and its impact on sustainability.
Evaluate full implementation.
