Dealing with scale and scope issues in stated preference experiments

A key issue for the Choice Modelling analyst is that policy needs may require values for tradeoffs at different levels of scope and scale. However, it is unclear whether values from a study in one context of scope and scale can be simply extrapolated or transferred to another context. The focus of this chapter is to explore the issues of scope and scale in choice modelling valuation experiments in relation to the Great Barrier Reef, with the aim of identifying how values may be sensitive to the structure and context in which they have been offered.
