Evaluating the cost effectiveness of adding straw bedding (shortened as EE - environmental enrichment) on pig welfare.
Unmodeled assumptions:
1. The only outcome metric we look at is reduction in tail-biting injuries. (This seems likely to be the most important identifiable metric, and I'd be somewhat surprised [20%] if reduction in tail biting accounts for less than 10% of the impact)
2. Disregarding additional indirect effects
