Correlations among human capital markers

A. Pairwise correlations between height and cognitive assessments
	Cognitive assessments (z scores)
	Raven's Prog Matrices	Fluid Intelligence	Working memory
	Raven's Prog Matrices	Fluid Intelligence	Immediate	Delayed

ln(height)	0.241 (0.013)	0.243 (0.013)	0.183 (0.014)	0.167 (0.014)
Raven's score		0.550 (0.010)	0.405 (0.011)	0.394 (0.011)
Fluid intelligence			0.418 (0.012)	0.395 (0.012)
Working memory: Immediate				0.777 (0.007)

B. Multivariable correlations between height and cognitive assessments
	ln(height)	Raven's score
	(1)	(2)
Raven's score	0.549 (0.066)
Fluid intelligence	0.599 (0.070)	0.482 (0.014)
Working memory: Immediate	0.257 (0.091)	0.128 (0.018)
Working memory: Delayed	0.048 (0.090)	0.124 (0.018)
R²	0.079	0.345

Note: Sample is 5,304 males. Cognitive scores are averages for each respondent across assessments and converted to z scores using the overall sample mean and standard deviation. Standard errors in parentheses robust to arbitrary forms of heteroskedasticity.
