Abstract
We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases. We also find that emission intensity decreased over the study period. Second, we find that environmentally adjusted productivity growth is higher than unadjusted productivity growth. Technological change contributed more to both environmentally adjusted and unadjusted productivity growth than did efficiency change. Third, the estimated shadow price for GHG emissions was CAN$286 per metric ton. Nous estimons la croissance de la productivité ajustée sur le plan environnemental ainsi que le prix implicite (shadow price) pour les fermes laitières de l'Ontario. Nous utilisons une fonction de distance directionnelle orientée vers les intrants et des données au niveau des exploitations couvrant la période de 2000 à 2020. Premièrement, nous constatons que, bien que les émissions de gaz à effet de serre (GES) par vache augmentent avec des rendements laitiers plus élevés, l'intensité des émissions diminue à mesure que le rendement laitier par vache s'accroît. Nous observons également que l'intensité des émissions a diminué au cours de la période étudiée. Deuxièmement, nous constatons que la croissance de la productivité ajustée sur le plan environnemental est supérieure à la croissance de la productivité non ajustée. Le changement technologique a davantage contribué à la croissance de la productivité — tant ajustée que non ajustée — que l'amélioration de l'efficacité. Troisièmement, le prix implicite estimé des émissions de GES pour le secteur laitier ontarien s’élève à 286$ CA par tonne métrique d’émissions.
