Biometric technology in rural credit markets
Identity theft is a common crime the world over. In developing countries, the damage caused by identity theft and identity fraud goes far beyond the individual victim, however, and ultimately creates a direct impediment to progress, particularly in credit markets. Recent research reveals that biometric technology can help reduce these problems. A biometric is a measurement of physical or behavioral characteristics used to verify or analyze identity. Common biometrics include a person’s fingerprints; face, iris, or retina patterns; speech; or handwritten signature. These are effective personal identifiers because they are unique and intrinsic to each person, so, unlike conventional identification methods (such as passport numbers or government-issued identification cards), they cannot be forgotten, lost, or stolen. Recent advances in recognition technology coupled with increases in both digital storage capacity and computer processing speeds have made biometric technology (for example, ocular or fingerprint scanners) feasible in many applications, from controlling restricted building access to allowing more effective delivery of targeted government programs with large-scale identification systems, such as those being implemented in India by the Unique Identification Authority of India. Biometric technology can also improve access to credit and insurance markets, especially in countries that do not have a unique identification system, where identity fraud—the use of someone else’s identity or a fictitious one—to gain access to services otherwise unavailable to an individual is rather common. For example, lenders in Malawi describe past borrowers who purposefully defaulted then tried to obtain a fresh loan from the same or another institution under a false identity. And, although less common in developing countries because markets are less developed, the potential for sick individuals without healthcare coverage to use the insurance policy of a friend or relative does exist. The response of lenders and insurance companies has been to restrict the supply of such services to the detriment of the greater population, not just those people committing identity fraud.Biometric technology, Commodities, conditional cash transfers, credit, Insurance, rural areas, Subsidies,
Group versus Individual Liability: Long Term Evidence from Philippine Microcredit Lending Groups
Group liability in microcredit purports to improve repayment rates through peer screening, monitoring, and enforcement. However, it may create excessive pressure, and discourage reliable clients from borrowing. Two randomized trials tested the overall effect, as well as specific mechanisms. The first removed group liability from pre-existing groups and the second randomly assigned villages to either group or individual liability loans. In both, groups still held weekly meetings. We find no increase in default and larger groups after three years in pre-existing areas, and no change in default but fewer groups created after two years in the expansion areas.microfinance, group lending, group liability, joint liability, social capital, micro-enterprises, informal economies, access to finance
Group Versus Individual Liability: A Field Experiment in the Philippines
This working paper by CGD non-resident fellow Dean Karlan explores whether group liability in lending practices improves lender's overall profitability and the poor's access to financial markets. Group liability is a common microcredit lending mechanism that makes a group, rather than an individual recipient, responsible for repayment. It claims to improve repayment rates by providing incentives for peer's to screen, monitor and enforce each other's loans. But some argue that group liability actually discourages good clients from borrowing by creating tension among group members and causing dropouts, jeopardizing growth and sustainability. Also, bad clients can "free ride" off of good clients causing default rates to rise. In this paper, Karlan and his co-authors discuss the results of a field experiment at a bank in the Philippines, where they randomly reassigned half of the existing group liability centers as individual liability centers. They find that converting group liability to individual liability, while keeping aspects of group lending like weekly repayments and common meeting place, does not affect the repayment rate, and actually attracts new clients. This paper is one in a series of six CGD working papers by Dean Karlan on various aspects of microfinance (Working Paper Nos. 106 –111).group liability, lending practices, financial markets, repayment rates, free ride, Philippines
Finding Missing Markets (and a disturbing epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya
In much of the developing world, many farmers grow crops for local or personal consumption despite export options which appear to be more profitable. Thus many conjecture that one or several markets are missing. We report here on a randomized controlled trial conducted by DrumNet in Kenya that attempts to help farmers adopt and market export crops. DrumNet provides smallholder farmers with information about how to switch to export crops, makes in-kind loans for the purchase of the agricultural inputs, and provides marketing services by facilitating the transaction with exporters. The experimental evaluation design randomly assigns pre-existing farmer self-help groups to one of three groups: (1) a treatment group that receives all DrumNet services, (2) a treatment group that receives all DrumNet services except credit, or (3) a control group. After one year, DrumNet services led to an increase in production of export oriented crops and lower marketing costs; this translated into household income gains for new adopters. However, one year after the study ended, the exporter refused to continue buying the cash crops from the farmers because the conditions of the farms did not satisfy European export requirements. DrumNet collapsed in this region as farmers were forced to sell to middlemen and defaulted on their loans. The risk of such events may explain, at least partly, why many seemingly more profitable export crops are not adopted.Field Experiment, Export Crop, Food Safety Standards

Votar : no tan fĂ cil com sembla, però podrĂem fer-ho millor!
Aquest article té un doble objectiu. D'una banda, volem fer veure com efectivament el problema no és pas una trivialitat, sinó que té molt de sentit adoptar un punt de vista matemà tic, amb definicions precises i demostracions rigoroses. D'altra banda, també volem incidir en les implicacions prà ctiques d'aquesta anà lisi. En particular, veurem com els mètodes de votació més senzills tenen defectes importants que podrien ser corregits mitjançant la utilització d'altres mètodes més elaborats
Les equacions de Navier-Stokes. Un repte al determinisme NewtoniĂ
S'examina la qüestió de l'existència i unicitat de solució de les equacions de Navier-Stokes no estacionà ries. Es posa especial èmfasi en les implicacions filosòfiques i la perspectiva històrica. L'exposició pretén acostar-se al nucli del problema tot mantenint un llenguatge al menys tècnic possible
Group versus Individual Liability: A Field Experiment from the Philippines
Group liability is often portrayed as the key innovation that led to the explosion of the microcredit movement, which started with the Grameen Bank in the 1970s and continues on today with hundreds of institutions around the world. Group lending claims to improve repayment rates and lower transaction costs when lending to the poor by providing incentives for peers to screen, monitor, and enforce each other’s loans. However, some argue that group liability creates excessive pressure and discourages good clients from borrowing, jeopardizing both growth and sustainability. Therefore, it remains unclear whether group liability improves the lender’s overall profitability and the poor’s access to financial markets. We worked with a bank in the Philippines to conduct a field experiment to examine these issues. We randomly assigned half of the 169 pre-existing group liability “centers” of approximately twenty women to individual-liability centers (treatment) and kept the other half as-is with group liability (control). We find that the conversion to individual liability does not affect the repayment rate, and leads to higher growth in center size by attracting new clients
