Status quo bias, multiple priors and uncertainty aversion

[PDF] from uni-muenchen.de
Full text - MIT Libraries
P Ortoleva - Games and Economic Behavior, 2010 - Elsevier
Motivated by the extensive evidence about the relevance of status quo bias both in
experiments and in real markets, we study this phenomenon from a decision-theoretic
prospective, focusing on the case of preferences under uncertainty. We develop an ...

The price of flexibility: towards a theory of thinking aversion

[PDF] from uni-muenchen.de
P Ortoleva - 2008 - mpra.ub.uni-muenchen.de
The goal of this paper is to model an agent who dislikes large choice sets because of the"
cost of thinking" involved in choosing from them. We take as a primitive a preference relation
over lotteries of menus and impose novel axioms that allow us to separately identify the ...

[PDF] Incomplete preferences under uncertainty: Indecisiveness in beliefs vs. tastes

[PDF] from nyu.edu
EA Ok, P Ortoleva… - Memio, New York University, 2008 - files.nyu.edu
Abstract We investigate the classical Anscombe# Aumann model of decision# making under
un# certainty without assuming the completeness axiom. We deduce the exact nature of
preferences in this setup, and give a simple example that shows why one cannot use state ...

[PDF] Theory of product differentiation in the presence of the attraction effect

[PDF] from unb.br
EA Ok, P Ortoleva… - 2010 - unb.br
Abstract We apply the theoretical model of endogenous reference-dependence of Ok,
Ortoleva and Riella (2011) to the theory of vertical product differentiation. We analyze the
standard problem of a monopolist who offers a menu of alternatives to consumers of ...

[PDF] Aspirations and growth: a model where the income of others acts as a reference point

[PDF] from caltech.edu
F Bogliacino… - 2011 - hss.caltech.edu
Abstract We study an OLG model in which the average income of the society acts as a
reference point for the agents' utility on consumption. To model this we use the functional
form developed in behavioral economics to study reference-dependence: prospect theory. ...

[PDF] Status Quo Bias, Ambiguity and Rational Choice

[PDF] from gtcenter.org
P Ortoleva - 2008 - gtcenter.org
Abstract Motivated by the extensive evidence about the relevance of status quo bias both in
experiments and in real markets, a number of recent papers have studied this phenomenon
from a decision-theoretic prospective. This paper focuses as well on this topic, albeit in the ...

[PDF] Modeling the Change of Paradigm: Non-Bayesian Reactions to Unexpected News

[PDF] from caltech.edu
P Ortoleva - 2010 - wordsmatter.caltech.edu
Abstract Despite its normative appeal and widespread use, Bayes' rule has two well-known
limitations: first, it does not predict how agents should react to an information to which they
assigned probability zero; second, a sizable empirical evidence documents how agents ...

[PDF] It's all about society: Growth when the consumption of others acts as a reference point

[PDF] from uniandes.edu.co
F Bogliacino… - 2009 - economia.uniandes.edu.co
Abstract We model a standard OLG growth model in which agents are reference dependent
and use the average consumption of the society as a reference point. In line with the
standard literature in reference dependence, we model this by assuming that the utility ...

[PDF] Objective Lotteries as Ambiguous Objects: Allais, Ellsberg, and Hedging

[PDF] from upf.edu
M Dean… - 2011 - econ.upf.edu
Abstract We derive axiomatically a model in which the Decision Maker can exhibit
simultaneously both the Allais and the Ellsberg paradoxes in the standard setup of
Anscombe and Aumann (1963). Using the notion of 'subjective', or 'outcome'mixture of ...

[PDF] Uncertain probabilities vs. uncertain outcomes: An experimental study of attitudes towards ambiguity

[PDF] from brown.edu
K Eliaz… - 2010 - econ.brown.edu
Abstract. The traditional Ellsberg-type experiment involves the choice between options that
contains no ambiguity (N), and options in which the probability of winning is ambiguous,
while the amount of the prize is not (P). The typical finding is that subjects prefer N to P, ...

[PDF] The Behavior of Others as a Reference Point: Prospect Theory, Inequality, and Growth

[PDF] from caltech.edu
F Bogliacino… - 2011 - hss.caltech.edu
Abstract The vast literature that studied the consequences of reference-dependence on
standard economic models has focused only on two special cases of reference point: the
one in which it is the agent's past behavior, and the one in which it is her expectations. In ...

[PDF] The behavior of others acts as a reference point: An application of prospect theory

[PDF] from siecon.org
F Bogliacino… - 2011 - siecon.org
Abstract A vast literature has been devoted to analyzing the consequences of
referencedependence on economic models. However, most of the literature has focused
only on two special cases of reference point: the one in which it is the agent's past ...

[PDF] Hypothesis Testing and Multiple Priors$

[PDF] from caltech.edu
P Ortoleva - hss.caltech.edu
Abstract We extend the Hypothesis Testing model of Ortoleva (2010) to the case in which the
agent is ambiguity averse both before and after she receives information. In particular, we
model an agent who ranks acts according to the MaxMin Expected Utility model of Gilboa ...

[PDF] from caltech.edu

Abstract We study the relation between ambiguity aversion and the Allais paradox. To this
end, we introduce a novel definition of hedging which applies to objective lotteries as well as
to uncertain acts, and we use it to define a novel axiom that captures a preference for ...
