Hotter years are associated with lower economic output in developing countries. The study shows that the effect of temperature on labor is an important part of the explanation. Using microdata from selected firms in India, the researchers estimate reduced worker productivity and increased absenteeism on hot days. Climate control significantly mitigates productivity losses. In a national panel of Indian factories, annual plant output falls by about 2% per degree Celsius. This response appears to be driven by a reduction in the output elasticity of labor. The research estimates are large enough to explain previously observed output losses in cross-country panels.
