本文利用印度十年期人口普查（1981-2011）数据，发现昼夜变暖（夜间和白天温度升高）对农业工资劳动份额具有不同的偏效应。尽管两者都减少了谷物产量和耕种面积，但只有白天最高温度升高会局部提高收获价格，这与一个模型一致：夜间变暖冲击土地，而白天变暖同时冲击土地和劳动生产率。夜间变暖使季节性工人和自耕农转向农业劳动；白天变暖则将劳动力推向季节性边际。长期差异显示劳动力分化发生在农村地区。在城镇中，两者都降低了非农业工人份额。
英文摘要
This paper shows how the composition of local economic activity shifts decadally under diurnal warming (higher nighttime and daytime temperatures) within Indian districts (1981--2011). Warmer nights raise, warmer days lower agricultural wage-labour shares. Though warmer days and nights both contract grain production and area under cultivation, only warmer days raise local harvest prices. Long differences show the labour divergence is within the rural population. In towns, both margins depress non-agricultural worker shares. These results are consistent with a model where warmer days shock land and labour productivity, but warmer nights are land-biased shocks in agriculture.
