This paper provides an alternative theory of price adjustment resting on consumer loss aversion in the price dimension. In line with prospect theory the perceived losses from price increases are weighted stronger in the consumer s utility function than the perceived gains resulting from price...

We consider fundamental questions of arbitrage pricing arising when the uncertainty model incorporates volatility uncertainty. With a standard probabilistic model, essential equivalence between the absence of arbitrage and the existence of an equivalent martingale measure is a folk theorem, see...
