Against the background of rising nutrition-related diseases such as obesity, type-II-diabetes, and arteriosclerosis, advancing healthier lifestyles is a highly relevant health policy issue. The food industry and retailers play a key role in this context, since they decide on formulation and prices of process food products supplied. However, from an economic perspective, it is still poorly understood which incentives firms face to offer products with a high health value and how these incentives are affected by consumer preferences, policy interventions and competition. The objective of this project is to investigate health-relevant firm behaviour related to product reformulation and pricing and to draw conclusions for policies and welfare. The analysis rests on advanced econometric methodologies and concepts from industrial organization. Comprehensive data on new product introduction and sales of a large retailing company provide the basis to estimate differentiated brand-level demand systems. Specific impacts of nutrient profiles and health and nutrition claims on substitutive processes will be examined by means of the distance metrics-approach. These estimates are then used together with cost information to establish a structural market model which allows modelling of pricing and innovation strategies under different policy and competition scenarios and changing consumer preferences.

在肥胖、ii型糖尿病和动脉硬化等营养相关疾病不断增加的背景下，促进更健康的生活方式是一个高度相关的卫生政策问题。食品工业和零售商在这方面发挥着关键作用，因为他们决定供应的加工食品的配方和价格。然而，从经济角度来看，人们对企业提供具有高健康价值的产品所面临的激励措施以及这些激励措施如何受到消费者偏好、政策干预和竞争的影响仍然知之甚少。这个项目的目标是调查与产品改型和定价有关的与健康有关的企业行为，并为政策和福利得出结论。该分析基于先进的计量经济学方法和产业组织的概念。某大型零售公司新产品引进和销售的综合数据为估计差异化品牌级需求系统提供了依据。将采用距离度量法审查营养概况以及健康和营养要求对替代工艺的具体影响。然后将这些估计与成本信息一起使用，以建立一个结构性市场模型，该模型允许在不同政策和竞争情景以及不断变化的消费者偏好下对定价和创新策略进行建模。
