The geometry of finite equilibrium datasets

Journal of Mathematical Economics, 2009, vol. 45, issue 5-6, 391-396

Abstract: We investigate the geometry of finite datasets defined by equilibrium prices, income distributions, and total resources. We show that the equilibrium condition imposes no restrictions if total resources are collinear, a property that is robust to small perturbations. We also show that the set of equilibrium datasets is pathconnected when the equilibrium condition does impose restrictions on datasets, as for example when total resources are widely noncollinear.
