The present paper considers a class of general equilibrium economics when the primitive uncertainty model features uncertainty about continuous-time volatility. This requires a set of mutually singular priors, which do not share the same null sets. For this setting we introduce an appropriate...

If agents are ambiguity-averse and can invest in productive assets, asset prices can robustly exhibit indeterminacy in the markets that open after the productive investment has been launched. For indeterminacy to occur, the aggregate supply of goods must appear in precise configurations but the...

In der bundesdeutschen Debatte über ein wünschenswertes Finanzausgleichssystem werden Effizienzaspekte weitgehend vernachlässigt. Es läßt sich jedoch zeigen, daß Finanzausgleichsregelungen Allokationsstörungen hervorrufen. Dies wird in dieser Arbeit anhand einer theoretischen Analyse...

In this paper we study the welfare effect of a monopoly innovation. Unlike many partial equilibrium models carried out in previous studies, general equilibrium models with non-price-taking behavior are constructed and analyzed in greater detail. We discover that technical innovation carried out...

We study the existence of equilibria with endogenously complete markets in a continuous-time, heterogenous agents economy driven by a multidimensional diffusion process. Our main results show that if prices are real analytic as functions of time and the state variables of the model then a...
