摘要：
since the mapping of the human genome in 2004, biologists have demonstrated genetic links to the expression of several income-enhancing physical traits. to illustrate how heredity produces intergenerational economic effects, this study uses one trait, beauty, to infer the extent to which parents' physical characteristics transmit inequality across generations. analyses of a large-scale longitudinal study in the u.s., and a much smaller data set of chinese parents and children, show that a one standard-deviation increase in parents' looks is associated with a 0.4 standard-deviation increase in their child's looks. a large data set of u.s. siblings shows a correlation of their beauty consistent with the same expression of their genetic similarity, as does a small sample of billionaire siblings. coupling this estimate with parameter estimates from the literatures describing the impact of beauty on earnings and the intergenerational elasticity of income suggests that one standard-deviation difference in parents' looks generates a 0.06 standard-deviation difference in their adult child's earnings, which amounts on average to additional annual earnings in the u.s. of about $2300.

主讲人简介：
larry han is an assistant professor in the department of health sciences at northeastern university, as well as an impact engine fellow of the real-world healthcare navigator. his research focuses on developing novel statistical and machine learning methods to leverage real-world data to improve decision-making, including robust and efficient estimation and inference of treatment effects using large-scale data generated from electronic health records and clinical trial data. active areas of research include causal inference, conformal prediction, data integration, federated and transfer learning, and sensitivity analysis.
he obtained his phd in biostatistics at harvard university, advised by professor tianxi cai and professor lorenzo trippa. he completed a postdoctoral fellowship in health care policy at harvard medical school, advised by professor sharon-lise normand. he received an am in biostatistics from harvard, an mphil in healthcare operations from the university of cambridge, an ma in global affairs from tsinghua university, and a bs in public health and biostatistics from unc - chapel hill.
摘要：
federated or multi-site studies have distinct advantages over single-site studies, including increased generalizability, the ability to study underrepresented populations, and the opportunity to study rare exposures and outcomes. however, these studies are challenging due to the need to preserve the privacy of each individual's data and the heterogeneity in their covariate distributions. we propose a novel federated approach to derive valid causal inferences for a target population using multi-site data. we adjust for covariate shift and covariate mismatch between sites by developing multiply-robust and privacy-preserving nuisance function estimation. our methodology incorporates transfer learning to estimate ensemble weights to combine information from source sites. we show that these learned weights are efficient and optimal under different scenarios. we showcase the finite sample advantages of our approach in terms of efficiency and robustness compared to existing approaches. finally, we showcase the utility of our methodology for estimating covid-19 vaccine efficacy (moderna vs. pfizer) across geographic regions, and variations in congenital heart surgery quality across racial/ethnic groups. our findings have implications for the efficient allocation of scarce resources.

主讲人简介：
craig palsson is an assistant professor of economics in the huntsman school of business at utah state university. he is interested in how historical political economy affects modern underdevelopment, with a special interest in the economic history of haiti. he has published in journals such as the journal of public economics, the journal of urban economics, and the journal of economic history. he is also the creator of the popular market power channel on youtube.
摘要：
we investigate the connection between incomplete property rights and plot size. incomplete property rights create transaction costs in the land market, which should have two effects on plot size: transaction costs (1) decrease plot size and (2) increase the variation in plot sizes. we test these hypotheses using newly collected archival data from haiti. we measure incomplete property rights using haiti’s tradition of families jointly owning land and find that the patterns in the data are consistent with these property rights creating large transaction costs in the land market. these results inform the discussion of small farms around the developing world and of haiti’s economic development.
