A unifying approach to measuring climate change impacts and adaptation
提出一种统一方法，同时利用天气和气候的变动来估计短期和长期影响，直接衡量适应程度，避免以往方法的遗漏变量偏差，并应用于研究气候变化对当地空气污染的影响。
We develop a unifying approach to estimating climate impacts and adaptation, and apply it to study the impact of climate change on local air pollution. Economic agents are usually constrained when responding to daily weather shocks, but may adjust to long-run climatic changes. By simultaneously exploiting variation in weather and climate, we identify both the short- and long-run impacts on economic outcomes, and measure adaptation directly as the difference between those responses. As a result, we identify adaptation without making extrapolations of weather responses over time or space, and overcome omitted variable bias concerns from prior approaches.
