We randomly split the Innovation Panel of Understanding Society into groups, and to ask respondents within each group different variants of a question about how their spending, saving and debt responses would respond to receipt of a hypothetical windfall.
In one half of the sample we would ask how much individuals would change their spending after an initial routing question (“would you increase spending, decrease spending or leave spending the same?”). In the second half of the sample, we would immediately ask for a pound change in spending without this routing. Within these treatments, we would also randomly assign individuals to either report how their spending, saving, debt and transfer behaviour would change over the next three months, or to report how it would change over the next twelve months and to either report how they would respond to either a £500 or a £2500 windfall.
We will then compare response across different treatments.
