Information sources for non-market values
Tranche 1 CRC studies
 Other published studies
 Grey literature
 Potentially new studies to fill key gaps

Using the existing information
Need for values to be used in different contexts
than the original studies
 Too expensive and slow to do original studies
every time
 Aim is to transfer or extrapolate existing results
to new contexts
 This is not a new idea

“Benefit Transfer”
They have developed
systematic approaches
to transferring values
 Do it in a way that
maximises validity
 Recognise the
reasonable limits to
transferring values

Identify the priority value types
Understand the contexts where they are needed
Design the tool to suit their needs and capabilities
Test the tool’s usability and usefulness with them
Use the international experts to review our
approach
