Abstract
Starting in 2007, several city and state governments have
implemented restaurant related dietary policies to the overall
health outcomes of their constituents. This paper intends to
estimate the average treatment effect of the joint treatment of
trans fat bans and
menu labeling law on both aggregate measure health outcomes
and
individual-level health outcomes. To overcome the problem of policy
overlapping and hidden selection bias, I apply propensity
score
method for the first stage estimation and inverse probability
weighting estimator for average treatment effect on the aggregate
prevalence
of hypertension and coronary heart disease. We find trans fat ban
decreases the prevalence of coronary heart disease by 2 percentage
point.
The average treatment effect of multiple overlapping policies
slightly
decreases the prevalence of coronary heart disease by 1.4
percentage
point. The average treatment effect on the treated of multiple
overlapping policies decreases the prevalence of coronary heart
disease by
1.59 percentage point. I also use individual-level data to estimate
the
effect of Baltimore trans fat ban on the prevalence of
hypertension.
I apply difference-in-differences method and improve the
reliability of
inference by wild bootstrap procedures, I find Baltimore trans fat
ban
decreases the prevalence of hypertension among the elderly by
4.65
percentage point in linear probability model
