Prof. Riedel presents at the DFG-Forschungszentrum "MATHEON" Jan. 17.
on "Intertemporal Equilibria with Knightian Uncertainty: Insurance and Market Breakdown".

Abstract:

We study a dynamic and infinite-dimensional model with Knightian uncertainty modeled by incomplete multiple prior preferences. In interior effcient allocations, agents share a common risk-adjusted prior and use the same subjective interest rate. Interior effcient allocations and equilibria coincide with those of economies with subjective expected utility and priors from the agents' multiple prior sets. We show that the set of equilibria with inertia contains the equilibria of the economy with variational preferences anchored at the initial endowments. A case study in an economy without aggregate uncertainty shows that risk is fully insured, while uncertainty can remain fully uninsured. Pessimistic agents with Gilboa–Schmeidler's max-min preferences would fully insure risk and uncertainty.
