Description

Dear US Support,

I noticed that there are often "seaming effects"
when merging BHPS and UKHLS. For instance, this happens
with savings due to the increase of proxy respondents in Understanding Society
(but this is just one of the several cases).

Since the year in which UKHLS started to be surveyed coincides with the
beginning of the Great Recession, I am interested in understanding whether
sudden increases or decreases in the proportions of data are due to the
introduction of new units or to the worsening of economic circumstances.
Is there any work that could help me in clarifying this doubt?

Thank you and best,
Lydia
