Multi-Partial Equilibrium Analysis

Opposite goods: Eg simultaneously solve for demand for abortion policy and demand for no abortion policy

1. No abortion can extend left into negative Q, or
2. No abortion can extend downward into negative P, or
3. No abortion can be represented as an opportunity cost in the price of supply (legislator is cost the support of opposition) and/or an external social cost
4. Abortion policy has a Q because 0 and 1, but then there are infinite intermediary positions (eg Roe vs Wade is such a position where sometimes legal, 2 trimester rule, there could be a 1 trimester rule, 1.2, etc)
