comparing across waves
100%
Description
Hello,
I wanted to know if it is possible to compare the effect of a variable in wave 1 with its effect in wave 5.
For example, has education a stronger effect in the probabilities of employment in 2009/2010 than in 2013/14?
At the naked eye, there seems to be a difference in the effect across waves. However, do you know if there might be a way to actually test this?
I would need to pool waves I assume. In that case, how should I weight the cases?
Many thanks in advance.

Dear Carolina,
To select the weights you will need to first decide on what you want to represent: either people over time (then use appropriate w5 weight) or events (then you can pool data and the weights you use will depend on the analysis).
Hope this helps,

Thanks Olena.
I realize that if I pool data I would need to have "individuals x wave" as unit of analyses, which might be complicated in terms of weighting...
I will get back to you if I make a decision on this.
Thanks
