Question 22
You are interested in the relationship between crime rate and police expenditure at a state level. Suppose that states tend to
increase budgets for police expenditure in response to high crime rates. If you run the following regression using OLS:

you are faced with which of the following threats to internal validity?
O There is no threat to internal validity in this case.
Simultaneous causality
Sample selection bias
O Misspecification of the functional form
