Researching Customization: The Data, the Methods, and the Cases

  • Eva Thomann
Part of the International Series on Public Policy book series (ISPP)


This chapter introduces the data, methods and cases that form the basis of the empirical study. The research presented here was originally a comparative research project that provided advice to the Swiss federal government about ensuring legal equivalence with community law. In order to explore the patterns, causes and consequences of customization, I employ a nested comparative case study design using innovative set-theoretic methodologies. Veterinary drug policies regulate important aspects of food safety in the EU single market. I compare their customization in four older member states—Austria, France, Germany and the United Kingdom—and the differentially integrated non-member, Switzerland. These countries are comparable in their regulatory contexts, but each of them displays distinct patterns of differentiated implementation.
