项目摘要

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.

描述（由申请人提供）：虽然污染对人类健康的影响已经得到了很好的确定，但由于缺乏数据，了解各种影响的努力受到了限制。这个应用程序试图填补一个重要的空白，在这项研究的重点是工人的生产力，一个简洁的总结措施的影响，通常被忽视的分析和设计的环境政策的多个发病渠道。该应用程序的主要目的是研究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，将估计温度和臭氧与工人生产力相关的统计模型。农业工人的使用将限制污染测量问题，因为工人对他们的接触有有限的自由裁量权，随着时间的推移，通过使用工人固定效应，跟踪工人可以控制工人的时不变特征。该应用程序的第二个目的是探索调节环境条件与工人生产力之间关系的因素，例如工人经验，年龄和性别以及通过先前暴露的适应性。通过估计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人的一些渠道。鉴于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。公共卫生关系：环境法规的主要目标是保护人类健康，目前的法规要求了解污染对健康的全面影响。通过研究环境条件对农业工人生产力的影响，我们的项目提供了一个简洁的总结措施的影响，通常被忽视的分析和环境政策的设计中的多个发病渠道。
