There are four requirements for establishing value of statistical life (VSL) numbers for use in cost‐benefit analyses based on transfers from the existing primary SP studies: i) A database of SP studies; ii) Criteria for assessment of the quality
of primary SP studies, iii) Benefit transfer (BT) techniques, and iv) Benefit transfer guidelines. Here the two last requirements are described in more detail. Two main groups of BT techniques are described: unit value transfer and function
transfer; which includes meta‐analyses. The BT guidelines for VSL are based on an eightstep procedure which establishes a base value with a value range.
