About the Scottish Stated Preference Network (SSPN)
The idea of creating a joint platform and infrastructure that facilitates cross-disciplinary discussions and collaborations about stated preference methods (SPMs) in Scotland was born in 2014 at a choice modelling workshop hosted by the University of Stirling. This idea was build on in 2015 in a subsequent choice modelling workshop at the Health Economics Research Unit in Aberdeen and two organised stated preference session at the Scottish Economic Society conference in 2016.

The SSPN was formed to share knowledge, skills and techniques across researchers in Scotland. The network aims to be a source of stimulation and creativity, which benefits researchers at each of the participating institutions and the SPM research in Scotland.

About stated preference methods in Scotland
The term SPMs describes a class of survey based economic tools that are used to explore individuals' preferences for market or non-market goods (e.g. health care or environmental amenities). SPMs are based on individuals' direct or indirect statements (e.g. choices) about their valuation of hypothetical goods and their characteristics. Examples of stated preference methods are:

- Discrete Choice Experiments (DCEs)
- Best-Worst Scaling (BWS)
- Contingent Valuation Methods (CVMs)
- Transfer Price Methods (TPMs)
- Conjoint Analysis (CA)
- Time Trade-Off (TTO)
- Standard Gamble (SG)

SPM research in Scotland has an international reputation for leading the application and methodological advancement of SPMs for the valuation of health care or environmental amenities. For example, the Health Economic Research Unit (HERU) at the University of Aberdeen has developed health-focussed choice experiments, tested the validity of DCEs and used qualitative research alongside SPMs. The University of Stirling has expertise in survey design, experimental design, and econometric modelling of the choice data and the University of St Andrews has strengths in the economic valuation of the environment and ecosystem services, policy analysis, and leads the way in a number of methodological aspects.
