Notes:
1. Though Table 11 is labeled a table and is double-spaced in the .pdf file, we are thinking it might be more accurate to reproduce it as a figure while still labeling it as a table. We would like to know what you think about this.   
2. Footnote 7 contains space to put the location on the AER website where the above .pdf of the technical appendix can be found.
