The main objective of the research was to develop a theoretical model for price construction in the agri-food sector, which should enable better transparency and efficiency of pricing policies in the food supply chain. The central part of the article focuses on the data set, in which the data sources and the economic analysis methodology are presented in detail. Based on this analysis, a theoretical model for pricing was developed, which is presented in more detail in a separate chapter. The model focuses on prices in three sectors (primary production, food processing industry and distribution/retail) of different food and agri-food chains and offers concrete solutions to improve pricing in these chains. The final chapter contains guidelines and recommendations for the practical application of the model with the aim of improving the transparency and effectiveness of pricing policy in the agri-food sector. The overall report represents an important contribution to understanding the behaviour and responsiveness of agri-food systems to specific cost changes and provides useful guidance for policy makers and stakeholders in the agri-food sector.
