Abstract We propose and develop an algebraic approach to revealed preference. Our dispenses with non-algebraic structure, such as topological assumptions. provide axioms of preference that subsume previous classical show a data set is rationalizable if only it consistent axiom.

In order to be able to conduct a test of the (core) utility hypolhesis that is not confounded with tests of (subsidiary) hypotheses that economic agents all have the same preferences and that their preferences are weakly separable, it is necessary to use data that are disaggregated and complete. In order 10 carry out a utility hypothesis test with complete data, revealed preference theory must ...

I characterize joint choice behavior generated by the pure strategy Nash equilibrium solution concept by an extension of the Congruence Axiom of Richter(1966) to multiple agents. At the same time, I relax the “complete domain” assumption of Yanovskaya(1980) and Sprumont(2000) to “closed domain.” Without any restrictions on the domain of the choice correspondence, determining pure strategy Nash ...
