Abstract (EN)
We characterize the excess demand function in the one-consumer model. We describe the relation between the direct and indirect utility functions. As an application of our result, we derive a short proof of the celebrated Sonnenschein–Mantel–Debreu theorem on the decomposition of aggregate excess demand.
