comparing across waves
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.

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,
