    We analyze a repeated cheap-talk game in which the receiver is privately informed about the conflict of interest between herself and the sender and either the sender or the receiver controls the stakes involved in their relationship. We focus on payoff-dominant equilibria that satisfy a Markovian property and show that if the potential conflict of interest is large, then the stakes increase over time, i.e., "starting small" is the unique equilibrium arrangement. In each period, the receiver plays the sender’s ideal action with positive probability and the sender provides full information as long as he has always observed his ideal actions in the past. We also show that as the potential conflict of interest increases, the extent to which the stakes are back-loaded increases, i.e., stakes are initially smaller but grow faster.

    The expansion of digital financial services raises serious consumer protection concerns, including fraud, especially in developing countries. This column reports findings from an online experiment in Kenya which suggest that conventional scam detection tips do not improve individuals' ability to distinguish between scams and genuine messages. Rather, they make people over-cautious - a result partly driven by official communication often including scam markers.

    We test the effectiveness of a behavioral approach designed to empower socioeconomically disadvantaged adolescents. The approach leverages adolescents’ desire for social status and is grounded in the idea that self-persuasion might yield a more robust behavioral change in challenging adolescents than direct lecturing. We enlist socially connected senior students with high emotional intelligence as ``student-teachers'' and entrust them with delivering an empowerment curriculum to their junior peers. Using randomized variation in program implementation, we show that this indirect targeting empowers targeted adolescents, leading them to improve their social environment. The program reduces disciplinary incidents and anti-social behavior among student-teachers and their friendship networks while fostering supportive network ties between senior and junior students. The program also lowers the tolerance for anti-social behavior, measured by the willingness to destroy unfairly gained payoffs in a third-party punishment game. Our study offers a cost-effective way to help disadvantaged adolescents escape neighborhood disadvantages.

    The recent expansion of digital financial products leads to severe consumer protection issues such as fraud and scams. As these potentially decrease trust in digital services, especially in developing countries, avoiding victimization has become an important policy objective. In an online experiment, we first investigate how well individuals in Kenya identify phone scams using a novel measure of scam identification ability. We then test the effectiveness of scam education, a commonly used approach by banks and institutions for fraud and scam prevention. We find that common tips on how to spot scams do not significantly improve individuals' scam identification ability, i.e., the distinction of scams from genuine messages. This null effect is driven by an increase in correctly identified scams and a decrease in correctly identified genuine messages. We interpret this as an increase in caution. In addition, we find suggestive evidence that genuine messages which contain scam-like features are more likely to be misclassified, highlighting the importance of a careful design of official communication.

    We investigate how adolescents’ social status in their peers' eyes shapes the way they view their social climate in secondary schools. Utilizing novel data on over 10,000 students, we construct comprehensive measures of social status and perceived social climate for each student, including a sense of belonging, perceived behavioral norms, and bullying experience. We show that while central and well-connected students are positive about their social environment, less central and socially isolated students view it as hostile. Our results highlight the importance of improving the relational dynamics of adolescents in disadvantaged schools to create better learning environments for all.

  9. Building social cohesion in ethnically mixed schools

    We evaluate the impact of an educational program that aims to build social cohesion in ethnically mixed schools by developing perspective-taking ability in children. The program is implemented in a high-stakes context where the ethnic composition in schools has changed due to a massive influx of refugee children. We measure a comprehensive set of outcomes that characterize a cohesive school environment, including peer violence incidents, the prevalence of inter-ethnic social ties, and prosocial behavior. Using randomized variation in program implementation, we find that the program significantly lowers peer violence and victimization on school grounds. The program also reduces the likelihood of social exclusion and increases inter-ethnic social ties in the classroom. We find that the program significantly improves prosocial behavior, measured by incentivized tasks: treated students exhibit significantly higher trust, reciprocity, and altruism toward each other as well as toward anonymous out-school peers. We show that this enhanced prosociality is welfare improving from the ex-post payoff perspective. We investigate multiple channels that could explain the results, including ethnic bias, impulsivity, empathetic concern, behavioral norms, and perspective-taking. Children’s increased effort to take others’ perspectives emerges as the most robust mechanism to explain our results.

  11. Optimal delegation of sequential decisions

    We analyze delegation of a set of decisions over time by an informed principal to a potentially biased agent. Each period the principal observes a state of the world and sends a “cheap-talk” message to the agent, who is privately informed about her bias. We focus on principal-optimal equilibria that satisfy a Markovian property and show that if the potential bias is large, then the principal assigns less important decisions in the beginning and increases the importance of decisions towards the end. In the beginning of their relationship, the biased agent acts exactly in accordance with the principal’s preferences, while towards the end, she starts playing her own favorite action with positive probability and gradually builds up her reputation. Principal provides full information in every period as long as he has always observed his favorite actions in the past. If we interpret the evolution of the importance of decisions over time as the career path of an agent, this finding fits the casual observation that an agent’s career usually progresses by making more and more important decisions and provides a novel explanation for why this is optimal. We also show that the bigger the potential conflict of interest, the lower the initial rank and the faster the promotion.
