A new integral for capacities, different from the Choquet integral, is introduced and characterized. The main feature of the new integral is concavity, which might be interpreted as uncertainty aversion. The integral is then extended to fuzzy capacities, which assign subjective expected values...

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.

This note argues that many employees under-contribute to so-called flexible spending accounts. A simple rule-of-thumb is developed for making optimal contributions (for risk neutral employees): After-tax income net of (uncertain) medical expenditures will be maximized if you contribute to your...

This study examines the role of national culture on an issue which is central to competitive strategy: whether to maintain flexibility or commit to a strategic direction. We consider that equity investments in foreign partners may be initiated as the first step in a sequential acquisition...

We study the issue of project choice when a risk-averse agent must choose whether to invest in two projects of the same type (focus) or of different types (diversification). Projects of the same type are subject to common type-specific shocks. Hence focusing is more risky within each period, but...

I explore how and and to what extent policy uncertainty can account for the observed long-run cross-country differences in capital price and levels of aggregate investment and output. I present a model economy where the industry-level policy-related investment cost is uncertain. Holding the...

This paper aims at analysing the effects of learning on the individual behaviour in an experiment that requires cooperation and coordination within teams. Using artificial agents, different social contests are created, as training environments. The results confirm previous findings (on the...

The goal of the paper is to study how a menu of options affects decisions of a rational agent facing uncertainty over future payoff streams. Using the real options approach, we demonstrate that multiple options not only increase the barrier which the underlying stochastic variable has to reach...

This paper examines the influence of implicit information associated with the occurrence of avalanches on willingness to pay (WTP) values for a risk prevention of dying in an avalanche. We present results of a contingent valuation (CV) study carried out in Austria in two different periods (fall...

Upon observing a signal, a Bayesian decision maker updates her probability distribution over the state space, chooses an action, and receives a payoff that depends on the state and the action taken. An information structure determines the set of possible signals and the probability of each...
