Dear Statalist Members,

I appreciate very much your assistance in the following question
(which might save me a lot of time in my research).

I have an unbalanced panel of public-housing tenants. They are offered
the option to purchase their rental units and face different reduction
rates from the full apartment price.

Below I provide an example of three tenants (appt ==2851 | appt==2862
| appt==2906),

My question refers to the reduction rate column. I would like to
generate a new variable, which reflects the last reduction rate the
tenant faces, which is different from the current one (or equal to the
current one in the case that this is the first reduction rate the
tenant faces).

 For tenant 2906 (for example) the numerical value of this variable
should be 58.98 for periods 0-4, 59.38 for periods 5-7, 57.89 for
periods 8-10 etc.

I would like to thank you in advance for your assistance

Yuval
