1. Given existing variables year and month, . gen newdate=(year-1960)*12+month-1 . format newdate %tm 2. I assume you mean panel, i.e. you want the initial value for some variable, say agehead, for each household (each cross-section means looking over all households at a given point in time), and I assume you have a household ID. . bys hhid (newdate): gen init_agehead=agehead[1] See -fillin- for how to fill in the missing zero values you describe in the first paragraph below.
