Periodic solutions in multivariate invariance arguments
Abstract. Inspired by the recent results of A. E. Abbas we determine continuous multivariate utility functions invariant with respect to a wide family of transformations related to the shift transformations.
Keywords: multivariate utility function, invariance, periodic solution, additive function, exponential function.
