Exposure to and recall of violence reduce short-term memory and cognitive control (with F. Bogliacino, G. Grimalda, and P. Ring)
  Proceedings of the National Academy of Science, vol. 114, no. 32 (2017), 8505-8510

 

Idea: Show that the exposure and recall of violence has significant negative effects on short-term memory and cognitive-control, with experiments in Colombia.

 

Abstract: Previous research has investigated the effects of violence and warfare on individuals’ well-being, mental health, and individual prosociality and risk aversion. This study establishes the short- and long-term effects of exposure to violence on short-term memory and aspects of cognitive control. Short-term memory is the ability to store information. Cognitive control is the capacity to exert inhibition, working memory, and cognitive flexibility. Both have been shown to affect positively individual well-being and societal development. We sampled Colombian civilians who were exposed either to urban violence or to warfare more than a decade earlier. We assessed exposure to violence through either the urban district- level homicide rate or self-reported measures. Before undertaking cognitive tests, a randomly selected subset of our sample was asked to recall emotions of anxiety and fear connected to experiences of violence, whereas the rest recalled joyful or emotionally neutral experiences. We found that higher exposure to violence was associated with lower short-term memory abilities and lower cognitive control in the group recalling experiences of violence, whereas it had no effect in the other group. This finding demonstrates that expo- sure to violence, even if a decade earlier, can hamper cognitive functions, but only among individuals actively recalling emotional states linked with such experiences. A laboratory experiment conducted in Germany aimed to separate the effect of recalling violent events from the effect of emotions of fear and anxiety. Both factors had significant negative effects on cognitive functions and appeared to be independent from each other.

Allais, Ellsberg, and Preferences for Hedging (with Mark Dean)
  Theoretical Economics, vol. 12 (2017), 377–424

 

(Previous Title: Objective Lotteries as Ambiguous Objects: Allais, Ellsberg,and Hedging)

 

Idea: Model an agent who exhibits both Allais and Ellsberg-like behavior in the setup of Anscombe and Aumann (1963). Generalizes Gilboa and Schmeidler (1989) to allow for Allais-type behavior.

 

Abstract: Two of the most well-known regularities observed in preferences under risk and uncertainty are ambiguity aversion and the Allais paradox. We study the behavior of an agent who can display both tendencies at the same time. We introduce a novel notion of preference for hedging that applies to both objective lotteries and uncertain acts. We show that this axiom, together with other standard ones, is equivalent to a representation in which the agent: 1) evaluates ambiguity using multiple priors, as in the model of Gilboa and Schmeidler (1989); 2) evaluates objective lotteries by distorting probabilities as in the Rank Dependent Utility model, but using the worst from a set of distortions. We show that a preference for hedging is not sufficient to guarantee an Ellsberg-like behavior if the agent violates Expected Utility for objective lotteries; we provide a novel axiom that characterizes this case, linking the distortions for objective and subjective bets.

Stochastic Choice and Preferences for Randomization (with Marina Agranov)
  Journal of Political Economy, vol. 125, no. 1 (February, 2017), 40–68

 

(Previous title: Stochastic Choice and Hedging)

 

Idea: Experimental paper in which we show that the majority of subjects choose to give a stochastic choice. This is in line with the interpretations of stochastic choice as emerging from an explicit preference for randomizing, as opposed to emerging from random utility or mistakes.

 

Abstract: We conduct an experiment in which subjects face the same questions repeated multiple times, with repetitions of two types: 1) following the literature, the repetitions are distant from each other; 2) in a novel treatment, the repetitions are in a row, and subjects are told that the questions will be repeated. We find that a large majority of subjects exhibit stochastic choice in both cases. We discuss the implications for models of stochastic choice.

Multidimensional Ellsberg (with Kfir Eliaz)
  Management Science, vol. 62, no. 8 (August 2016), 2179-2197.

 

(Previous title: A Variation on Ellsberg and Uncertain Probabilities vs. Uncertain Outcomes: An Experimental Study of Attitudes Towards Ambiguity)

 

Idea: Modifies Ellsberg experiments to allow for bet directly on the composition of the urn. The behavior observed suggests of restrictions of the set of priors.

 

Abstract: The classical Ellsberg experiment presents individuals with a choice problem in which the probability of winning a prize is unknown (uncertain). In this paper, we study how individuals make choices between gambles in which the uncertainty is in different dimensions: the winning probability, the amount of the prize, the payment date, and many combinations thereof. While the decision-theoretic models accommodate a rich variety of behaviors, we present experimental evidence that points at systematic behavioral patterns: (i) no uncertainty is preferred to uncertainty on any single dimension and to uncertainty on multiple dimensions, and (ii) “correlated” uncertainty on multiple dimensions is preferred to uncertainty on any single dimension.

Pathos & ethos: Emotions and willingness to pay for tobacco products (with F. Bogliacino, C. Codagnone, G. Veltri, A. Chakravarti, G. Gaskell, A. Ivchenko, F. Lupianez-Villanueva, F. Mureddu, C. Rudisill)
  PLOS ONE, 10(10): e0139542. doi:10.1371/journal.pone.0139542 (October 2015)

 

Idea: Study emotional and behavioral responses to anti-smoking pictures on cigaretters packaging.

 

Abstract: In this article we use data from a multi-country Randomized Control Trial study on the effect of anti-tobacco pictorial warnings on an individual’s emotions and behavior. By exploiting the exogenous variations of images as an instrument, we are able to identify the effect of emotional responses. We use a range of outcome variables, from cognitive (risk perception and depth of processing) to behavioural (willingness to buy and willingness to pay). Our findings suggest that the odds of buying a tobacco product can be reduced by 80% if the negative affect elicited by the images increases by one standard deviation. More importantly from a public policy perspective, not all emotions behave alike, as eliciting shame, anger, or distress proves more effective in reducing smoking than fear and disgust.

Are Conservatives Overconfident? (with Erik Snowberg)
  European Journal of Political Economy, vol. 40 Part B (December 2015), 333-344

 

Abstract: Recent studies suggest psychological differences between conservatives and liberals, including that conservatives are more overconfident. We use a behavioral political economy model to show that while this is undoubtedly true for election years in the current era, there is no reason to believe that conservative ideologies are intrinsically linked to overconfidence. Indeed, it appears that in 1980 and before, conservatives and liberals were equally overconfident.

Cautious Expected Utility and the Certainty Effect (with Simone Cerreia-Vioglio and David Dillenberger)
  Econometrica, Vol. 83, No. 2 (March, 2015), 693–728

 

Idea: Novel class of preferences that satisfy the Certainty Effect (Allais Paradox) in which the decision maker has a set of utilities and considers the most pessimistic one of them. Characterized via one key axiom, Negative Certainty Independence (plus basic axioms).

 

Abstract: Many violations of the Independence axiom of Expected Utility can be traced to subjects’ attraction to risk-free prospects. The key axiom in this paper, Negative Certainty Independence (Dillenberger, 2010), formalizes this tendency. Our main result is a utility representation of all preferences over monetary lotteries that satisfy Negative Certainty Independence together with basic rationality postulates. Such preferences can be represented as if the agent were unsure of how to evaluate a given lottery p; instead, she has in mind a set of possible utility functions over outcomes and displays a cautious behavior: she computes the certainty equivalent of p with respect to each possible function in the set and picks the smallest one. The set of utilities is unique in a well-defined sense. We show that our representation can also be derived from a ‘cautious’ completion of an incomplete preference relation.

Overconfidence in Political Behavior (with Erik Snowberg)
  American Economic Review, Vol. 105, No. 2 (February 2015), 504-535.

 

Idea: Studies the role of overconfidence in ideology formation and voting, showing how it is linked with ideological extremism and higher turnout. It then tests the predictions in novel survey data, finding a strong support.

 

Abstract: This paper studies, theoretically and empirically, the role of overconfidence in political behavior. Our model of overconfidence in beliefs predicts that overconfidence leads to ideological extremeness, increased voter turnout, and increased strength of partisan identification. Moreover, the model makes many nuanced predictions about the patterns of ideology in society, and over a person’s lifetime. These predictions are tested using unique data that measure the overconfidence, and standard political characteristics, of a nationwide sample of over 3,000 adults. Our numerous predictions find strong support in these data. In particular, we document that overconfidence is a substantively and statistically important predictor of ideological extremeness and voter turnout.

Revealed (P)Reference Theory (with Efe Ok and Gil Riella)
  American Economic Review, Vol. 105, No. 1 (January 2015), 299–321.

 

Idea: Characterize choice that violate Warp because of an endogenous reference point, like in the case of the attraction effect.

 

Abstract: The goal of this paper is to develop, axiomatically, a revealed preference theory of reference-dependent behavior. Instead of taking the reference for an agent as exogenously given in the description of a choice problem, we suitably relax the Weak Axiom of Revealed Preference and we the existence of reference alternatives as well as the structure of choice behavior conditioned on those alternatives.

Hypothesis Testing and Ambiguity Aversion
  Rivista di Politica Economica, Issue 3 (July-September) 2014, 45–64.

 

(Previous Title: Hypothesis Testing and Multiple Priors)

 

Idea: We extends the model of non-Bayesian updating in Ortoleva (2012), Hypothesis Testing mode, to the case of ambiguity averse agents.

 

Abstract: We study a model of non-Bayesian updating, based on the Hypothesis Testing model of Ortoleva (2012), for ambiguity averse agents. Agents ranks acts following the MaxMin Expected Utility model of Gilboa and Schmeidler (1989) and when they receive new information they update their set of priors as follows: If the information is such that all priors in the original set of priors assign to it a probability above a threshold, then the agent updates every prior in the set using Bayes’ rule. Otherwise: she looks at a prior over sets of priors; she updates it using a rule similar to Bayes’ rule for second order beliefs over sets; finally, she chooses the set of priors to which the updated prior over sets priors assigns the highest likelihood.

The Price of Flexibility: Towards a Theory of Thinking Aversion
  Journal of Economic Theory, Vol. 148, No. 3 (May 2013), 903--934

 

Idea: Model an agent who prefers a smaller menu because of the cost of thinking involved in choosing from the bigger one. Defines a notion of Thinking Aversion, and characterizes this cost.

 

Abstract: We study the behavior of 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 a ‘genuine’ preference over the content of menus from the cost of choosing from them. Using this, we formally define the notion of Thinking Aversion, much in line with the definitions of risk or ambiguity aversion. We characterize such preference as the difference between an affine evaluation of the content of the menu and a function that assigns to each menu a thinking cost. We provide conditions that allow us to interpret the cost of thinking about a menu as the cost that the agent has to sustain to figure out her preferences in order to make her choice.

Modeling the change of Paradigm: Non-Bayesian Reaction to Unexpected News
  American Economic Review, Vol. 102, No. 6 (October 2012), 2410--2436.

 

Idea: A model in which agents are Bayesian after `normal' events, but have non-Bayesian reactions to low probability events, and whose behavior is modeled also after zero-probability ones.

 

Abstract: Bayes' rule has two well-known limitations: 1) it does not regulate the reaction to zero-probability events; 2) a sizable empirical evidence documents systematic violations of it. We introduce a behavioral rule, Dynamic Coherence, and show that it is equivalent to an alternative updating rule, the Hypothesis Testing model. According to it, the agent follows Bayes' rule if she receives information to which she assigned a probability above a threshold. Otherwise, she looks at a prior over priors; updates it using Bayes' rule for second-order priors; and chooses the prior to which the updated prior over priors assigns the highest likelihood. We apply the model to construct, in an example, a refinement of Perfect Bayesian Nash Equilibrium.

Incomplete Preferences under Uncertainty: Indecisiveness in Beliefs vs. Tastes (with Efe Ok and Gil Riella)
  Econometrica, Vol. 80, No. 4 (July, 2012), 1791–1808

 

Idea: Studies incomplete preferences under uncertainty.

 

Abstract: We investigate the classical Anscombe-Aumann model of decision-making under uncertainty without the completeness axiom. We distinguish between the dual traits of "indecisiveness in beliefs" and "indecisiveness in tastes." The former is captured by the Knightian Uncertainty model, while the latter by the single-prior expected multi-utility model. We characterize axiomatically the latter model. Then, we show that, under Independence and Continuity, these two models can be jointly characterized by a means of a partial completeness property.

Status Quo Bias, Multiple Priors and Uncertainty Aversion
  Games and Economic Behavior, Vol. 69 (2010), 411-424

 

Idea: Characterize status-quo-dependent preferences under uncertainty. The agent keeps her status quo unless there is an option better than it for a set of priors. We also show that this implies that the agent is uncertainty averse.

 

Abstract: 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 axiomatic framework that takes as a primitive the preferences of the agent for each possible status quo option, and provide a characterization according to which the agent prefers her status quo act if nothing better is feasible for a given set of possible priors. We then show that, in this framework, the very presence of a status quo induces the agent to be more uncertainty averse than she would be without a status quo option. Finally, we apply the model to a financial choice problem and show that the presence of status quo bias as modeled here might induce the presence of a risk premium even with risk neutral agents.

Econographics (with Colin Camerer, Jonathan Chapman, Mark Dean, and Erik Snowberg)

 

Idea: Studies the correlation betweeen behavioral economic measures in a large-scale representative-sample incentivized survey. Find clear patterns.

 

Abstract: We study the pattern of correlations across a large number of behavioral regularities, with the goal of creating an empirical basis for more comprehensive theories of decision-making. We elicit 21 behaviors using an incentivized survey on a representative sample (n = 1,000) of the U.S. population. Our data show a clear and relatively simple structure underlying the correlations between these measures. Using principal components analysis, we reduce the 21 variables to six components corresponding to clear clusters of high correlations. We examine the relationship between these components, cognitive ability, and demographics, and discuss the theoretical implications of the structure we uncover.

Stochastic Impatience and the Separation of Time and Risk Preferences (with David Dillenberger and Daniel Gottlieb)

 

Idea: Studies the relation between Stochastic Impatience and models that separate time and risk preferences. Not easy to accomodate all.

 

Abstract: We study how the separation between time and risk preferences relates to a behavioral property that generalizes impatience to stochastic environments: Stochastic Impatience. We show that Stochastic Impatience holds if and only if risk aversion is "not too high" relative to the inverse elasticity of intertemporal substitution. This result has implications for many known models. For example, in the models of Epstein and Zin (1989) and Hansen and Sargent (1995), Stochastic Impatience is violated for all commonly used parameters. If Stochastic Impatience is taken normatively, this suggests a limit on the amount of separation between time and risk preference; otherwise, it provides a simple one-question test for it.

Time Lotteries and Stochastic Impatience (with Patrick Dejarnette, David Dillenberger, and Daniel Gottlieb)

 

(Previous titles: Time Lotteries, and Risk Attitude towards Time Lotteries.)

 

Idea: Studies time lotteries -- lotteries that pay a fixed amount in a random date. Experiment on this plus discussion on which models can accomodate it.

 

Abstract: We study preferences over lotteries that pay a fixed prize at an uncertain future date: what we call time lotteries. The standard model of risk and time preferences, Expected Discounted Utility, implies that individuals must be risk seeking towards such lotteries (RSTL). In contrast, we show experimentally that almost all subjects violate this property. Our main contributions are theoretical. First, we show that risk aversion over time lotteries can be captured by a generalization of Expected Discounted Utility that is obtained by keeping the behavioral postulates of Discounted Utility and Expected Utility. Second, we introduce a new property termed Stochastic Impatience, a risky counterpart of standard Impatience, and show that not only the model above, but also substantial generalizations that allow for non-Expected Utility and non-exponential discounting, cannot jointly accom- modate it and even a single instance of risk aversion over time lotteries (or, equivalently, any violation of RSTL), showing a fundamental tension between the two.

Deliberately Stochastic (with Simone Cerreia-Vioglio, David Dillenberger, and Gil Riella)

 

Idea: Study axiomatically stochastic choice as the outcome of a deliberate desire to randomize.

 

Abstract: We study stochastic choice as the outcome of deliberate randomization. We derive a general representation of a stochastic choice function where stochasticity allows the agent to achieve from any set the maximal element according to her underlying preferences over lotteries. We show that in this model stochasticity in choice captures complementarity between elements in the set, and thus necessarily implies violations of Regularity/Monotonicity, one of the most common properties of stochastic choice. This feature separates our approach from other models, e.g., Random Utility.

Willingness-To-Pay and Willingness-To-Accept are Probably Less Correlated than You Think (with Colin Camerer, Jonathan Chapman, Mark Dean, and Erik Snowberg)

 

Idea: Shows that Willingness to Pay and Willingness to Accept are very poorly correlated, if at all, in 2 large scale studies on representative samples.

 

Abstract: An enormous literature documents that willingness to pay (WTP) is less than willingness to accept (WTA) a monetary amount for an object, a phenomenon called the endowment effect. Using data from an incentivized survey of a representative sample of 3,000 U.S. adults, we add one (probably) surprising additional finding: WTA and WTP for a lottery are, at best, slightly correlated. Across all participants, the correlation is slightly negative. We also collect data from published, incentivized, studies, all run on university students, to analyze the correlation between WTA and WTP, which those studies did not examine. We document a correlation of 0.15-0.2, which is consistent with the correlation for high-IQ participants in our own data. While poorly related to each other, WTA and WTP are closely related to different measures of risk aversion, and relatively stable across time. Models of reference dependence can explain the cor- relations we observe in our data, but only with specific parameterizations. However, these models are inconsistent with other aspects of our data, suggesting the need for more theories and empirical studies of the processes of buying and selling.

Is it All Connected? A Testing Ground for Unified Theories of Behavioral Economics Phenomena (with Mark Dean)

 

(Previous titles: Is it All Connected? Understanding the Relationship Between Behavioral Phenomena , and Estimating the Relationship between Economic Preferences: A Testing Ground for Unified Theories of Behavior)

 

Idea: Studies with an experiment the empirical relation between behavioral phenomena like risk, ambiguity, and loss aversion, certainty, present, and status quo bias, endowment effect, updating speed, discounting, etc.

 

Abstract: We study the joint distribution of 11 behavioral phenomena in a group of 190 laboratory subjects and compare it to the predictions of existing models as a step in the development of a parsimonious, general model of economic choice. We find strong correlations between loss aversion and the endowment effect, risk aversion and discounting, compound lottery and ambiguity aversion, and between the Allais paradox and risk aversion. Our results support some, but not all attempts to unify behavioral economic phenomena through extensions to Cumulative Prospect Theory. Overconfidence and gender are also predictive of some behavioral phenomena.

An Explicit Representation for Disappointment Aversion and Other Betweenness Preferences (with Simone Cerreia-Vioglio and David Dillenberger)

Idea: Gives an explicit representation to Disappointment Averse preferences.

 

Abstract: One of the most well-known models of non-expected utility is Gul (1991)’s model of Disappointment Aversion. This model, however, is defined implicitly, as the solution to a functional equation; its explicit utility representation is unknown, which may limit its applicability. In this paper we show that an explicit representation can be easily constructed, using solely the components of the implicit one. We also provide a more general result: an explicit representation to the preferences in the Betweenness class that also satisfy Negative Certainty Independence (Dillenberger, 2010).

The Behavior of Others as a Reference Point (with Francesco Bogliacino)

 

(Previous title: Aspirations and growth: a model where the income of others acts as a reference point, and The Behavior of Others as a Reference Point: Prospect Theory, Inequality, and Growth)

 

Idea: Study growth when the average consumption of the society acts as a reference point for the consumers. Reference dependence is modeled using prospect theory.

 

Abstract: We study a model in which consumers are reference-dependent, modeled using prospect-theory, and their reference point is the average behavior of the society in that period. We show that in any of the equilibria of the economy after a finite number of periods the wealth distribution will become, and remain, either of perfect equality, or admit a ‘missing class’ (a particular form of polarization). We then study growth rates and show that, if we look at the equilibria with the highest growth, then the society with the highest growth rate is the one that starts with perfect equality. If we look at the equilibria with the lowest growth, however, then the society with a small amount of initial inequality is the one that attains the highest growth rate, while a society with perfect equality is the one with the lowest performance. All of these growth rates are weakly higher than the growth rate of a corresponding economy without reference-dependence.

Theory of Product Differentiation in the Presence of the Attraction Effect (with Efe Ok and Gil Riella)

 

Idea: Applies the model of "Revealed (P)Reference Theory" to the theory of product differentiation. Obtains that the presence of these biases might lead the economy back to an efficient equilibrium in which the monopolist extracts all the surplus.

 

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 different types, but we allow for agents to exhibit a form of endogenous reference dependence like the attraction effect. We show that the presence of such biases might allow the monopolist to overcome some of the incentive compatibility constraints of the standard problem, leading the economy back towards the efficient equilibrium in which the monopolist extracts all the surplus. We then discuss welfare implications, showing that an increase in the fraction of customers who are subject to the attraction effect might not only increase the monopolist’s profits and total welfare, but consumer’s welfare as well.

Thinking Aversion and Portfolio Choice

 

Idea: Apply the model in "The price of Flexibility" to a portfolio choice.

 

Abstract: This paper analyzes the investment decision of an agent who has to figure out the correct model to use in order to evaluate all available assets. This is a costly process. She can choose either to endure this cost, or to simplify her choice by looking only at a subset of the available assets. We show that such an agent tends to participate less in the market, to under-diversify her portfolio, or to diversify it naively, by investing equal amounts in a selection of assets. These predictions qualitatively match the empirical observations of the investments of households, both in general investment situations and in the choice of 401(k) plans. Moreover, in a partial equilibrium setting, if agents are not aware that others bear the cost of discovering which model to use, then even a small cost can induce a sizable effect on the equilibrium prices. This is due to a phenomenon similar to a multiplier: agents observe prices that are different than expected, and in turn modify expectations, which affect prices, which in turn affect expectations, and so on.
