The influence of weather conditions on dairy production
研究了气象变量如何通过影响奶牛生产力和饲料产量间接影响牛奶产量，利用西班牙阿斯图里亚斯地区383个奶牛场2006-2011年的数据，发现温暖天气因改善饲料生产而提高牛奶产量。
Abstract Relatively little attention has been paid in the economics literature to the effects of meteorological conditions on milk production. Meteorological variables can be expected to affect milk production through their impact on the productivity of cows and the production of foodstuff. Rather than including meteorological variables as inputs in the milk production process, we propose a production function where these variables affect the productivity of cows and the production of forage, thereby indirectly affecting milk production. Using production and meteorological data from the Spanish region of Asturias corresponding to 383 dairy farms observed during a six‐year period from 2006 to 2011, the results from our estimated production function show that meteorological variables have a significant impact on milk production. We find that milk production is higher under warm weather conditions due to improvements in forage production.
