Comparison of OLS and Tobit regressions: Outcome variable is the ratio of active leisure time to passive leisure time

Marginal effects for the 2002 Exercise of PCG (PCG_EX_02) regressor
Model OLS Tobit
with child characteristics .5077 (t=1.69) .5499 (t=1.95)
with child characteristics and family income .4288 (t=1.53) .4518 (t=1.77)
full model (controls are child characteristics, family income, PCG_ED and PCG_SMK) .3497 (t=1.46) .384 (t=1.61)

Notes: For these regressions the dependent variable is measured in levels. Authors’ analysis of time diary data from the 2007 CDS. t-stat in parenthesis. All regressions incorporate the PSID weights. All regressions use cluster-robust estimators for the standard errors. N = 1117.
