The Impact of Environmental Conditions on the Productivity of Agricultural Worker

描述（由申请人提供）：虽然污染对人类健康的影响已得到充分确认，但由于缺乏数据，了解所有影响的努力受到限制。该应用程序试图通过关注工人生产率来填补本研究中的一个重要空白，这是对多种发病率渠道影响的简洁总结衡量，而这些渠道通常在环境政策的分析和设计中被忽视。这项申请的主要目的是审查环境条件对农业工人生产力的影响。使用一个新的纵向数据集，其中包含与每日臭氧和温度测量相关的农业工人每日收获率的详细信息，将估计将温度和臭氧与工人生产力联系起来的统计模型。农业工人的使用将限制污染测量问题，因为工人对其暴露的自由裁量权有限，长期跟踪工人可以通过使用工人固定效应来控制时间不变的工人特定特征。该应用程序的第二个目标将探索调节环境条件和工人生产率之间关系的因素，如工人经验、年龄、性别以及通过先前暴露的适应。通过估算这些因素与环境条件相互作用的模型，这一目标的结果将有助于进一步阐明臭氧和温度影响个体的一些渠道。考虑到工人生产率对经济的重要性，即使是很小的影响，在整个经济中累积起来也可能转化为巨大的损失。因此，这些分析对臭氧和气候变化政策的设计及其分配效应具有重要意义。

DESCRIPTION (provided by applicant): While the effects of pollution on human health have been well established, efforts to understand the full range of impacts have been limited by a paucity of data. This application attempts to fill an important gap in this research by focusing on worker productivity, a succinct summary measure of the impacts of multiple morbidity channels that are typically overlooked in the analyses and design of environmental policy. The primary aim of this application will examine the impacts of environmental conditions on the productivity of agricultural workers. Using a novel longitudinal dataset with detailed information on daily harvest rates of agricultural workers linked to daily ozone and temperature measurements, statistical models that relate temperature and ozone to worker productivity will be estimated. The use of agricultural workers will limit pollution measurement concerns because workers have limited discretion over their exposure, and following workers over time enables opportunities to control for time invariant worker specific characteristics through the use of worker fixed effects. The secondary aim of the application will explore factors that moderate the relationship between environmental conditions and worker productivity, such as worker experience, age, and gender as well as adaptation via prior exposures. By estimating models that interact these factors with environmental conditions, the results from this aim will help to further elucidate some of the channels through which ozone and temperature impact individuals. Given the importance of worker productivity to the economy, even small effects may translate into large losses when aggregated across the economy. As a result, these analyses have important implications for the design of ozone and climate change policy as well as their distributional effects. PUBLIC HEALTH RELEVANCE: The primary goal of environmental regulations is to protect human health, and current regulations require understanding the full range of the health impacts of pollution. By examining the impact of environmental conditions on the productivity of agricultural workers, our project provides a succinct summary measure of the impacts of multiple morbidity channels that are typically overlooked in the analyses and design of environmental policy.
