This paper studies how much rural producers in developing countries can learn from their own experience to redress important information gaps. It builds a model of learning from experience and applies it using a rich dataset on cotton farmers in Pakistan. I test whether farmers learn from cultivation experience about the pest resistance of their seeds and use this information to improve selection and productivity. I find no such learning effect and this conclusion is robust to several parameters that could signal learning. The findings document the difficulty of parsing out and processing information from cultivation experience alone and point to the importance of information provision to producers by the government or external agencies.","PeriodicalId":290405,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123403721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We calibrate our model to detailed data for Cape Town, South Africa and show that the inclusion of social learning improves the prediction of excess fatalities, reducing the best-fit squared difference from 19.34 to 11.40. The inclusion of social learning both flattens and shortens the curves for infections, hospitalizations, and excess fatalities, which is qualitatively different from flattening the curve by reducing the contact rate or transmission probability through non-pharmaceutical interventions. While social learning reduces infections, this alone is not sufficient to curb the spread of the virus because learning is slower than the disease spreads. We use our model to study the efficacy of different vaccination strategies and find that vaccinating vulnerable groups first leads to a 72% reduction in fatalities and 5% increase in total infections compared to a random-order benchmark. By contrast, using a contact-based vaccination strategy reduces infections by only 0.9% but results in 42% more fatalities relative to the benchmark.","PeriodicalId":290405,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124706991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relative performance evaluations (RPE) are known to increase individual work morale but may negatively affect group morale because they create a sense of competition among members of a reference group. In a novel experiment, I vary whether or not members of a reference group obtain relative performance information on a task that is relevant for their social image or selfimage, a general knowledge test. I measure how this affects the subsequent willingness to help the productivity of others by sharing knowledge with them at a personal cost. I find that RPE cause members of a reference group to compete as intensely as under relative pay, compared to a baseline with no relative performance information and fixed piece-rates. It also increases the perceived social distance between them. Yet, I show that even after a performance competition, individuals are willing to help the productivity of others in the group. These findings advance our understanding of how relative concerns among co-workers affect the way they work together.","PeriodicalId":290405,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130644010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
