We introduce a combinatorial abstraction of two person finite games in an oriented matroid. We also define a combinatorial version of Nash equilibrium and prove that an odd number of equilibria exists. The proof is a purely combinatorial rendition of the Lemke-Howson algorithm

This paper examines capital tax competition in the presence of an interstate transfer policy without federal commitment. Lack of commitment implies that tax policy is chosen prior to federal transfers. The paper's main result is that ex-post federal policy internalizes horizontal fiscal...
