Hi All,
I have to compute the duration of a non-employment spell. Currently, I have identified the non-employment spells (which are defined as spells of unemployment and non-participation). However, when computing the duration, I am unable to get a cumulative sum for the number of months of non-participation.
Below is an example of my dataset:
The variables were generated according to the following code
Here the variable JOBESR is the variable which describes whether you are employed (jobesr==1), unemployed(jobesr==2) or not participating (jobesr==3), in the labour market. And the variables SSUID EENTAID and EPPPNUM are used to identify the individual in the dataset. The variable BEGIN computes any change in the labour market status. SPELL computes the number of spells of each type for labour market status and DURATION computes the duration of each labour market spell.
The variable DURATIONNONEMP currently computes the duration of each spell of non-employment (unemployment and non-participation) spell. However, I would like that the variable gives me the answer 26 for individual ID "0190037546300203" instead of 4, 1, 19. Since that individual has consecutive unemployment and non-participation spells for which I require the duration.
Any help on this would be great.
Thank you very much.
