This paper develops a behavioural asset pricing model in which traders are not fully rational as is commonly assumed in the literature. The model derived is underpinned by the notion that agents' preferences are affected by their degree of optimism or pessimism regarding future market states. It...

In this paper we introduce a new, analytically tractable model for decision-making under risk in which psychological characteristics related to the degree of optimism or pessimism of the decision-maker are considered. The model we propose, which is based on a two-parameter optimism weighting...

This paper studies the implications of arbitrage in a large asset market under conditions of (Knightian) uncertainty.First, I adapt the notion of arbitrage to a market in which the assets' returns are affected by uncertainty across probability distributions. The setting delivers the analog of...

The real estate derivatives market allows participants to manage risk and return from exposure to property, without buying or selling directly the underlying asset. Such market is growing very fast hence the need to rely on simple yet effective pricing models is very great. In order to take into...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering arbitrage-free nancial markets. A pricing formula is obtained for contingent claims written on n underlying assets following general Itô processes and without any...

The aim of this paper is to present a two-factor pricing model for convertible bonds, paying particular attention to the impact of volatility in the valuation process as suggested in previous studies. The model here proposed is discrete and the sources of uncertainty are the risk-free spot rate...
