1 A researcher is interested in identifying and estimating the causal effect of condomusage on venereal disease at the high school level. The researcher uses a simplemodel to determine the effectiveness of condom usage on reducing sexuallytransmitted diseases among sexually active high school students(1) infrate=Bo+B1conuse+B2percmale+B3avginc+B4city+u1,where infrate is the percent of sexually active students who have contractedvenereal disease, conuse is the percentage of boys who claim to regularly usecondoms, avginc is average family income, and city is a dummy variable indicatingwhether a school is in a city; the model is at the school level. The city has randomlygifted free condoms in high schools to students. Denote Z as the fraction of studentsthat accepted the condom gift at the school level.

The city has randor gifted free condoms in high schools to students. Denote Z as the fraction of stuc that accepted the condom gift at the school level.
