A note on the impact of the inclusion of an anchor number in the inflation expectations survey question

Inflation expectations surveys are receiving increasing attention. There is no optimal
approach and often limited discussion of key characteristics of individual surveys. We
use a South African dataset to argue that survey design should be given far more
attention as it may undermine our ability to use the data with confidence. Users of survey
data need to understand existing differences in survey design and the extent to which
survey data reflect decision-making shortcuts under uncertainty as opposed to a true
belief about what the public more generally really thinks expected inflation will be.
