Many social experiments are run in multiple waves, or are replications of earlier social experiments. In principle, the sampling design can be modified in later stages or replications to allow for more efficient estimation of causal effects. We consider the design of a two-stage experiment for estimating an average treatment effect, when covariate information is available for experimental subjects. We use data from the first stage to choose a conditional treatment assignment rule for units in the second stage of the experiment. This amounts to choosing the propensity score, the conditional probability of treatment given covariates. We propose to select the propensity score to minimize the asymptotic variance bound for estimating the average treatment... |

Gender gaps in income and level of position in the workplace are widespread. One explanation for this inequality is that the genders perform differently under competitive conditions, as previous experimental studies have found a significant gender gap in competitive tasks that are perceived to favor men. In this paper, we use a verbal task that is perceived to favor women and find no gender difference under competition per se. We also reject the hypothesis that a .stereotype threat. explains the inability of women to improve performance under competition. We propose an alternative explanation for gender inequality: namely, that women and men respond differently to time pressure. With reduced time pressure, competition in verbal tasks greatly increases the... |

This paper further tests dual interest theory and the metaeconomics approach to environmental choice, recognizing a possible role for empathy-sympathy (the basis for an internalized, shared other-interest) in tempering and conditioning the more fundamental tendency to pursue self-interest. To test, we focus on rivers flowing through agricultural areas carrying sediments, chemicals, and fertilizers which are making their way into downstream rivers and lakes. We use data from a framed experiment. Farmers decide on the usage of conservation technology to lessen impacts on the water quality in downstream areas, which is more costly. The results confirm our hypotheses, demonstrating that upstream farmers who practice conservation are tempering profit... |

Questions remain as to whether results from experimental economics games are generalizable to real decisions in non-laboratory settings. Furthermore, important questions persist about whether social capital can help solve seemingly missing credit markets. I conduct two experiments, a Trust game and a Public Goods game, and a survey to measure social capital. I then examine whether behavior in the games predicts repayment of loans to a Peruvian group lending microfinance program. Since the structure of these loans relies heavily on social capital to enforce repayment, this is a relevant and important test of the games, as well as of other measures of social capital. I find that individuals identified as "trustworthy" by the Trust game are in fact less... |
