We have modified some of the calculations in the gen_base and mobility codes. In the first, we have added 

	bys male: egen avgall = mean(totearn)
	gen permearnalt`yr' = avgall*totearn/avg	// This is because we want to control for age effects
	
In lines 388 to have permearnalt in the correct scale. This does not change the results. 
The mobility code has more changes. In particular, we have modified the transition matrix calculation to account for 0. Individuals with 0 permanent earnings are now grouped in one category only, whereas the rest of individuals (with positive permearnalt earnings, are separated in 10 groups, to a total of 11 rows in the transition matrix). See lines 240 to 266. We have also saved some summary stats within each cell (see line 248 for instance).
