Estimates of agents' risk aversion differ between market studies and experimental studies. We demonstrate that the estimates can be reconciled through consistent treatment of agents' tendency for narrow framing, regarding integration of background wealth as well as across risky outcomes: Risk...

We propose a new parametrization of Quantum Decision Theory (QDT), based on Rank Dependent Utility Theory (RDU). Using … experimental data made of choices between pairs of lotteries, we compare QDT with "classical" decision theories, RDU and Cumulative … decision makers as either RDU, RDU-based QDT, CPT or CPT-based QDT. Our major findings are the following: the quantum …

We assess the ability of different risk profiling measures to predict risk taking along a multi-stage decision process …-assessed risk tolerance measures are not suitable for predicting risk taking in any stage of the decision process. Among the …

Quantum decision theory (QDT) is a recently developed theory of decision making based on the mathematics of Hilbert … decision making. QDT describes a decision maker's choice as a stochastic event occurring with a probability that is the sum of … subjectivity on decision makers, the quarter law. We examine individual and aggregated (group) data, and find that the results are …

We present the first calibration of quantum decision theory (QDT) to an empirical data set. The data comprise 91 …. The prediction of choice reversal is then refined by introducing heterogeneity between decision makers through a … differentiation of the population into two similar sized groups in terms of "over-confident" and "contrarian" decision makers. This …

We study risk sharing games with quantile-based risk measures and heterogeneous beliefs, motivated by the use of internal models in finance and insurance. Explicit forms of Pareto-optimal allocations and competitive equilibria are obtained by solving various optimization problems. For Expected...

This paper argues that observations of non-stationary choice behavior need not necessarily imply specific properties of the individual's discount function. As we show, the observed quot;anomaliesquot; in intertemporal choice can alternatively be explained by an individual's perception of the...

We consider dynamic sublinear expectations (i.e., time-consistent coherent risk measures) whose scenario sets consist of singular measures corresponding to a general form of volatility uncertainty. We derive a càdlàg nonlinear martingale which is also the value process of a superhedging...

This paper analyzes optimal prevention in a situation of multiple, possibly correlated risks. We focus on probability reduction (self-protection) so that correlation becomes endogenous. If prevention concerns only one risk, introducing a second exogenous risk increases the level of prevention...

We use a survey approach to learn about valuation professionals' choices and implementations of valuation techniques in practice. The survey design allows us to control for a respondent's professional subgroup (e.g., consulting), education, experience, and valuation purpose characteristics. We...
