+- Using cooperative game theory to **model bargaining**
+  - Has precedents in labor and IO literature
+  - General solution concepts are **flexible** but often **not very tractable**

+- Provide a **tool-kit** for modeling **bargaining** in settings with one (few) **central player**(s) and many small ones
+  - Use **random order values as a general framework**
+  - **Relax** the **indispensable player** assumption
+  - **Generalize** existing results for the **heterogeneous small player case**

+- Random order values are a **convenient tool** for modeling bargaining
+  - **Analytically tractable**
+  - More **flexible** than the Shapley value or the we
