The objective of the project is to analyze the correlations between farm characteristics and their performance in order to better anticipate farmers' reactions to changes in public policies. Specifically, it aims to empirically explore how to optimize sustainable productivity growth at the farm level by: identifying and measuring systematic response patterns; considering the significant correlations and contexts (technology, organization, environment, location, political framework, etc.); and conducting comparisons both internationally (EU, Korea, Switzerland, Chile, Japan) and between sectors.
