Abstract

We prove existence of an Arrow-Debreu equilibrium when agents' preferences exhibit local substitution in the sense of Hindy, Huang, and Kreps (1992). Efficient allocations and supporting price functionals are identified and characterized. Under Hindy-Huang-Kreps preferences, equilibrium price processes are semimartingales for arbitrary endowments, but in general, they do not belong to the space suggested originally by Hindy and Huang (1992) due to an additional singular local time component.
