Identifying unemployment spells
Dear Understanding Society team,
I am trying to identify unemployment spells (and in particular job losses, i.e. moving from employment to unemployment) in both Understanding Society and the harmonised BHPS.
In both surveys, jbstat identifies individuals unemployed at interview. However, I am also interested in unemployment spells between waves. (I am not currently concerned with employment histories, i.e. unemployment spells before survey entry).
Specifically, I would like to identify person-wave observations in which individuals are employed at both t-1 and t, but experience one or more spells of unemployment between t-1 and t. In the BHPS, bw_njusp seems to do this: for instance, I find 2231 such observations (2.17% of the observations nonmissing on bw_njusp and employed at both t-1 and t). At first sight, w_nunmpsp_dv appears to be an equivalent variable for Understanding Society, however it identifies only 183 such observations (0.14% of the observations nonmissing on w_nunmpsp_dv and employed at both t-1 and t). So there appears to be a difference between bw_njusp and w_nunmpsp_dv - perhaps due to routing.
Is there any other way to identify spells of unemployment between waves for Understanding Society respondents (who report being employed at wave t-1 and at wave t)? In other words, is there any way to derive an equivalent of bw_njusp for Understanding Society (or identify job losses in some other way)?

An update - I have an idea as to why there is this discrepancy between bw_njusp and w_nunmpsp_dv, I'd be interested in your comments.
Looking at the questionnaires, it appears that the annual employment history is more thorough in the BHPS. For instance, picking the wave 5 questionnaire at random, the interviewer is instructed to read out: 'As we need to get as complete a picture as possible I'd like you to tell me about spells you may have had in our out of paid employment, even if they were just a few days ... [etc.]' (emphasis in original; page 52 of the EMPLOYMENT part of the questionnaire). A hand calendar is produced 'to help sort it out'.
In UKHLS by contrast, as far as I can tell the questionnaire does not appear to place the same emphasis on accounting for each day of the year and hence capturing all spells. The dates of spell ends are asked for but I don't see anything in the routing that directs the interviewer to try to account for gaps between spells. I guess doing so would take up already scarce interview time; so I suppose the discrepancy ultimately comes down to interview time in the UKHLS being scarce, and perhaps a comprehensive annual employment history (as in BHPS) being crowded out by other topics which aren't in the BHPS; the result being that the UKHLS annual employment histories pick up fewer employment, unemployment, and non-employment spells per person year (but generally the ones omitted would be the short ones that would only be picked up by prompts to account for as much of the year as possible).
Does this fit with your understanding?
(Also regarding my original question - I've now found the variables stendreas, jbendreas, reasend, nxtendreas, and jhstpy from the annual employment history modules and have used these to identify job losses.)
Apologies for the long message, your help is much appreciated.

Apologies for the delay in responding.
Yes, this is the reason for the change in wording. When the Understanding Society questionnaire was first being developed, there was a deliberate decision not to carry the full employment history each year.
