Marginal effects from OLS and Tobit regressions: Outcome variable is active leisure time (AL-1_07) on an average day (measured in seconds per day).

Marginal effects for the PCG_EX_02 regressor
Model OLS with dependent variable in levels Tobit with dependent variable in levels OLS with logged dependent variable Tobit with logged dependent variable
with child characteristics 604.416 (t=1.58) 618.484 (t=1.83) .628 (t=1.76) .762 (t=2.52)
with child characteristics and family income 425.093 (t=1.07) 405.339 (t=1.14) .319 (t=0.87) .586 (t=1.90)
full model (controls are child characteristics, family income, PCG education and PCG smokes) 249.753 (t=0.57) 284.670 (t=0.71) .289 (t=0.72) .515 (t=1.46)

Notes: Author’s analysis of time diary data from the 2007 CDS; t-statistics are in parenthesis. All regressions incorporate the PSID weights. All regressions use cluster-robust estimators for the standard errors. AL-1 is the narrow measure of children’s time spent engaged in active leisure endeavors. N = 1117.
