The Effectiveness of Environmental Public Policies in Multi-Level Food Supply Chains

The objective of this project is to assess the environmental impact of organic-friendly policies in agrifood markets. Since the environmental impact of food is mostly determined by household diet and consumption habits, taxes on organic products or subsidies on conventional products can be used to address environmental problems, and provide incentives for farmers and processors to promote sustainability. However, this is a challenging task due to the strategic behavior of the channel members, who potentially exploit their market power, which affects the effectiveness of public policies.
To evaluate the effectiveness of environmental public policies, we develop a structural model of demand and supply for the fluid milk sector allowing for strategic behavior of manufacturers, retailers, and farmers. We build on existing literature to estimate consumer demand based on retail scanner data and infer on both retailer and processor price-cost margins without observing cost data. However, the innovativeness of this approach is the integration of a strategic farm level into a three-tier supply chain model, which allows predicting changes of channel members’ behavior at all stages in response to public policies.
Having accurately modeled the complexity of the supply chain, we assess the impact of environmental public policies on prices, profits, and environmental indicators. In particular, we compare the efficiency of organic-friendly policies at the consumer-, at the processing- , and at the farm level.
