Policy Schemes for More Sustainable Dairy Farming: The Role of Financial Instruments and Policy Implementation Modes
通过瑞典离散选择实验，研究奶农对草饲养殖环境补偿方案的偏好，发现补偿金额、支付方式及实施主体（公共或私营部门）显著影响参与意愿，且农户存在异质性偏好。
ABSTRACT Dairy farming is faced with environmental, social and economic sustainability challenges, which call for the uptake of more sustainable farming practices. Policy schemes involving public and private sectors can support the uptake of more sustainable farming practices through the provision of incentives to farmers if designed appropriately. However, empirical research in designing such policy schemes is scarce. This paper examines dairy farmers’ preferences for policy attributes in environmental compensation schemes for more grass‐based feeding systems. Using data from a discrete choice experiment in Sweden and a hybrid latent class model, we find that while size of financial compensation matters, farmers’ likelihood of participation in grass‐based feeding schemes is also driven by how the financial compensation is designed and by non‐financial attributes of the policy schemes. Notably, we find three distinct groups of farmers who differ in their likelihood of participating and exhibit heterogeneous preferences for schemes with private versus public sector‐led implementation mode, and direct subsidy payment versus consumer price premium and tax relief. Furthermore, findings demonstrate that behavioral factors, including farmer attitudes toward different forms of compensation and risk aversion, partly explain the observed heterogeneous preferences. Overall, our findings highlight the need to accommodate preference heterogeneity in policy design to improve participation, especially in settings where the transition to more grass‐based feeding is challenging for farmers.
