Chetty Hendren 2015 Mobility Notes:

Chetty-Hendren give 25th and 75th parent income percentile ranks
		Child mean percentile ranks in national household income and individual income

Chetty et al. 2014 have relative mobility
		slope of child income rank vs. parent income rank from 0 to 100th percentile of parent income
		I think they use household income for most of their calculations

What types of effects are reported?
2014: Regress child rank on parent rank - R_i_c = a_c + b_c*P_i_c + e_i_c , where c is a CZ, i is an individual
	b_c is the measure of relative mobility for each CZ
	
	Parent and child income ranks from national income distribution	


2015: Percentile rank effects - "Every additional year spent growing up in Salt Lake
	City increases a child’s earnings by 0.166 percentiles (rmse 0.066) relative to an average CZ." (pp. 62)
	 

How to calculate a comparable measure from 2015?
(b_cz_75-b_cz_25)/(.75-.25) (make sure that the units are right)

How should we scale these correctly?
Chetty-Hendren (2015) - Preffered measure is child’s mean percentile rank in the national household income 
		(i.e., including own earnings and spouse earnings) distribution at age 26.
Chetty et al. (2014) - 30 years: "We define child family income in exactly the same way as parent family income.
		In our baseline analysis, we average child family income over the last two years in our data (2011
		and 2012), when children are in their early 30’s." (pp. 11)  
---> Scale the 2015 measures by 26 years, since there should not be any causal effects in the child's late 20's
