The purpose of this paper is to investigate the validity of some behavioral conjectures as alternative explanations of bank risk-taking behavior. We especially focus on the different valuation of gains and losses relative to a reference point, and the changing attitude toward risk conditional on...

This paper explores the implications of investors’ everyday mild feelings for aggregate asset returns. To this end, it introduces a novel class of state dependent preferences - happiness maintenance preferences - into the standard Mehra and Prescott (1985) economy by allowing investors’...

In this paper we extend the results of recent studies on the existence of equilibrium in finite dimensional asset markets for both bounded and unbounded economies. We do not assume that the individual's preferences are complete or transitive. Our existence theorems for asset markets allow for...

This paper presents a simple discrete time model for valuing real options. A short proof of optimal exercise rules for the standard problems in the real options theory is given in the binomial and trinomial models, and more generally, when the underlying uncertainty is modelled as a random walk...

A widely held belief in financial economics suggests that stock prices always adequately reflect all available information. Price movements away from fundamentals are assumed to occur only infrequently, if at all. „False“ prices are supposed to be corrected by the counter-actions of...

We explicitly solve the pricing problem for perpetual American puts and calls, and provide an efficient semi-explicit pricing procedure for options with finite time horizon. Contrary to the standard approach, which uses the price process as a primitive, we model the price process as the expected...

This paper proves existence of equilibrium and the arbitrage pricing theorem for an asset exchange economy, where the individual's preferences may be incomplete or intransitive. This extends existing results to a more general set of individual preferences. We also prove the arbitrage pricing...

We propose a quantum-like description of markets and economics. The approach has roots in the recently developed quantum game theory. Quantum Zeno paradoxes and noncomutative quantum mecanics are also discussed.

From the model of Hobijn and Jovanovic (2001), we modelize a technological shock with uncertainty. We assume that this technological shock appears in the shape of new firms. Only a part of these firms will be productive. Uncertainty relates to the identification of the viable firms. This...
