Abstract: Questions remain as to whether results from experimental economics games are generalizable to real decisions in non-laboratory settings. I conduct a survey and two experiments, a Trust game and a Public Goods game, to measure social capital. Social capital purports to provide incentives to individuals to abide by otherwise difficult to enforce contracts. I then examine whether behavior in the games predicts repayment of loans to a Peruvian group lending microfinance program. I find that individuals identified as "trustworthy " by the Trust game are more likely to repay their loans. Individuals identified as "trusting " default more and save less, suggesting that those who “trust ” more in the game are prone to taking bad risks. Behavior in a public goods game does not predict any future decisions in this context. Those with more positive attitudes towards society, as measured by three questions identical to those used in the General Social Survey, are more likely to repay their loans.

This paper reports the results from a laboratory microfinance experiment of group lending in the presence of moral hazard and (costly) peer monitoring. We compare peer monitoring treatments in which credit is provided to members of the group to individual lending treatments with lender monitoring. We find that if the cost of peer monitoring is lower than the cost of lender monitoring, peer monitoring results in higher loan frequencies, higher monitoring and higher repayment rates compared to lender monitoring. In the absence of monitoring cost differences, however, lending, monitoring and repayment behaviour is mostly similar across group and individual lending schemes. Within group lending, contrary to theoretical predictions, simultaneous and sequential lending rules provide equivalent empirical performance. JEL Classification: G21, C92, O2.

Self-help groups (SHGs) are the most common form of microfinance in India. We provide evidence that SHGs, composed of women only, undertake collective actions for the provision of public goods. Using a theoretical model, we show that an elected official, whose aim is to maximise re-election chances, would exert higher effort in providing public goods when private citizens undertake collective action and coordinate their voluntary contributions towards the same goods. This effect occurs although government and private contributions are assumed to be perfect substitutes. Using first-hand data on SHGs in India, we test the predictions of the model and show that, in response to collective action by SHGs, local authorities tackle a larger variety of public issues, and are more likely to tackle issues of interest to SHGs.

Motivated by recent controversies surrounding the role of commercial lenders in microfinance, we analyze borrower welfare under different market structures, considering a benevolent non-profit lender, a for-profit monopolist, and a competitive credit market. To understand the magnitude of the effects analyzed, we simulate the model with parameters estimated from the MIX Market database. Our results suggest that market power can have severe implications for borrower welfare, while despite possible information frictions competition typically delivers similar borrower welfare to non-profit lending. In addition, for-profit lenders are less likely to use joint liability than non-profits.

Using data from a panel of 48 U.S. states during 1997-2006, I present evidence that social capital reduces fatal traffic accidents by fostering pro-social behavior among drivers. I estimate simultaneous equation systems that model the incidence of interpersonal interaction-related versus non-interaction-related traffic outcomes, in which variation in endogenous social capital is identified using snow depth. My results show that social capital has a larger relative effect on multi-vehicle and junction-related fatalities and fatal crashes, incidents with respect to which motorist interaction is most critical to outcomes. The findings are robust to alternative specifications and measures of social capital.

Abstract This paper contrasts individual liability lending with and without groups to joint liability lending. By doing so, we shed light on an apparent shift away from joint liability lending towards individual liability lending. We show that individual lending with or without groups may constitute a welfare improvement so long as borrowers have sufficient social capital to sustain mutual insurance. Secondly, we explore how a purely mechanical argument in favour of the use of groups -namely lower transaction costs -may actually be used explicitly by lenders to encourage the creation of social capital.

I magine a nefarious researcher in economics who is only interested in finding a statistically significant result of an experiment. The researcher has 100 different variables he could examine, and the truth is that the experiment has no impact. By construction, the researcher should find an average of five of these variables statistically significantly different between the treatment group and the control group at the 5 percent level—after all, the exact definition of 5 percent significance implies that there will be a 5 percent false rejection rate of the null hypothesis that there is no difference between the groups. The nefarious researcher, who is interested only in showing that this experiment has an effect, chooses to report only the results on the five variables that pass the statistically significant threshold. If the researcher is interested in a particular sign of the result—that is, showing that this program “works ” or “doesn’t work” — on average half of these results will go in the direction the researcher wants. Thus, if a researcher can discard or not report all the variables that do not agree with his desired outcome, the researcher is virtually guaranteed a few positive and statistically significant results, even if in fact the experiment has no effect. This is of course the well-known problem of “data-mining. ” If the researcher can choose which results to report, it is easy to see how results can be manipulated. Casey, Glennerster, and Miguel (2012), for example, demonstrate in a real-world economics context how researchers with opposite agendas could hypothetically string together two opposite but coherent sets of results by cherry-picking either positive or negative statistically significant results.
