ABSTRACT: Motivated by the wide applications of distortion function and copulas in insurance and finance, this paper generalizes the notion of deterministic distortion function to a stochastic distortion function, i.e., a random process, and employs the defined stochastic distortion function to construct a so-called stochastic distorted copula. One method for constructing… more »

ABSTRACT: We study how inertia and personal experiences affect individual risk taking. Our research design relies on active portfolio decisions relating to inheritances to separate the effect of personal experiences from inertia, which otherwise would be observationally equivalent. Experience derives from investments in banks that… more »

ABSTRACT: This study investigates when forced sales of real estate turn into fire sales by using a natural experiment which allows us to separate supply and demand effects: Forced sales result from sudden death of house owners and are thus unrelated… more »
ABSTRACT: We examine the manner in which the population prevalence of disordered gambling has usually been estimated, on the basis of surveys that suffer from a potential sample selection bias. General population surveys screen respondents using seemingly innocuous “trigger,” “gateway” or “diagnostic stem” questions, applied before they ask the actual questions… more »

Published in 2016 in Journal of Cognition and Culture, Volume 16, Issue 5.
ABSTRACT: The Internet and social media have opened niches for political exploitation of human dispositions to hyper-alarmed states that amplify perceived threats relative to their objective probabilities of occurrence. Researchers should aim to observe the dynamic “ramping up”… more »
ABSTRACT: Index insurance was conceived to be a product that would simplify the claim settlement process and make it more objective, reducing transaction costs and moral hazard. However, index insurance also exposes the insured to basis risk, which arises because there can be a mismatch between the index measurement and the… more »

ABSTRACT: A principal source of interest in behavioral economics has been its advertised contributions to policies aimed at ‘nudging’ people away from allegedly natural but self-defeating behavior toward patterns of response thought more likely to improve their welfare. This has occasioned… more »
ABSTRACT: We take Cumulative Prospect Theory (CPT) seriously by rigorously estimating structural models using the full set of CPT parameters. Much of the literature only estimates a subset of CPT parameters, or more simply assume CPT parameter values from prior studies. Our data are from substantial laboratory experiments with undergraduate students… more »

ABSTRACT: Evidence of risk aversion in laboratory settings over small stakes leads to a priori implausible levels of risk aversion over large stakes under certain assumptions. One core assumption in statements of this calibration puzzle is that small-stakes risk aversion is observed over all levels of wealth, or… more »
