The welfare effect of advertising restrictions in the U.S. cigarette indust
ry depends upon the impact of advertising on consumer and producer surplus,
the transfer to consumers for being exposed to utility-reducing advertisin
g, and smoking externalities. We estimate a demand equation and a supply re
lation simultaneously and use the parameter estimates to generate predictio
ns of the impact of advertising restrictions on social welfare. Our results
show that advertising restrictions benefit producers by limiting competiti
on and generating higher industry profits, and such restrictions lower soci
al welfare if the external cost of cigarette smoking is sufficiently low.
