Notes

This example can promote an interesting discussion of instrument validity, and in particular, how a variable that is beyond our control – for example, whether the first two children have the same gender – can, nevertheless, affect subsequent economic choices. Students are asked to think about such issues in Computer Exercise C13 in Chapter 15. A more egregious version of this mistake would be to treat a variable such as age as a suitable instrument because it is beyond our control: clearly age has a direct effect on many economic outcomes that would play the role of the dependent variable.
