Plan

get list of things that Tom says I'm Missing

- Needs more citations
- Standard econometric concerns: Endogenetiy, Simultineatiy, etc.
- Needs to justify why I am doing what I am doing. What do I add? 
    Marketwide attempt to measure the impact of enrollment, an operational concern.
- 

Integrate additional literature I've worked with.
    - How big of a concern is operational results (about 22% of failures)
    - Topics of how to address issues and what issues arise are common (give a couple of examples)
    - Efforts to reduce failures include better pharmokinetics, attempts at improving enrollment, better enrollment prediction (huge lit).

Then look at my outline:
- How can I adjust it to address those missing bits?
- How can I simplify the structure?

Maybe a discussion of concerns about simultineity/endogeneity/other confounds/etc is where I 
bring up the confounding parameters and then build a list of how things interact.
I then use this to flesh out the DAG, and introduce the backdoor criterion.


I think I'll put this together as a bullet point draft, using the * and - 
notation for paragraphs and sentences respectively. Try to get the main points 
of each sentence/paragraph out.
