Book excerpt: Essays on Risk and Uncertainty: Insights from Behavioral Economics Sensitization, Excess Volatility, and Extraordinary Persistence It is well-documented that stock prices are more volatile than their underlying fundamentals. A consensus has emerged that time-varying risk-premia are the likely source of this excess volatility, but no consensus has emerged regarding the source of the time-varying risk-premia. Recent microeconomic research suggests that one likely source is that risk preferences are time-varying. This same literature also suggests that variation in risk preferences can be extraordinarily persistent, on the order of decades (see Malmendier, Tate, and Yan (2011)); however this persistence has not been explained by conventional models. In this paper, we derive a model to explain both excess volatility and extraordinary persistence. To do so, we draw from the literatures of medicine, psychology, and behavioral economics. Our basic framework is that people have adaptive emotions and that these adaptive emotions create adaptive risk-aversion. This process is called sensitization, which implies that people become more risk-averse after negative shocks (Kandel 2000). To conduct our analysis, we construct an overlapping generations model of the macroeconomy to study the effect of allowing agents to be sensitized to risk. We find two main results. First, the adaptive nature of risk preferences combined with the finite horizons of agents imply that economic activities, such as investment, are too risky on the intensive margin. Second, excess risk-intensity combined with the availability heuristic implies that agents undertake too little risk (too little investment) on the extensive margin. In order to characterize the optimal monetary policy, we follow Tirole (2006), who models risk through liquidity shocks, and we derive three policy implications for policymakers. First, diversification blunts the impact of time-varying risk aversion. As a result, there is a reason to think that equity financing, under which risk diversification is easier to achieve, leads to fewer risk distortions and faster steady-state growth. Second, countercyclical risk-aversion favors countercyclical monetary policy. Third, short-term asset purchases are shown to exacerbate risk distortions. In our model, monetary policy results in greater stabilization and faster growth when conducted through long-term asset purchases such as Quantitative Easing and Operation Twist. Reference Points, Leaders, and Organizational Culture The work of Akerlof and Kranton (2005) suggests that an organization's culture affects individual behavior by shaping preferences. Yet, within the economics literature, little is known regarding the properties of the optimal culture. In this paper, we use an agency setting to determine the cultural properties that best foster incentives. To do so, we break culture down into three components: a type of performance metric (either production or cost), an expected performance level or target (that serves as the reference point, following Koszegi and Rabin (2006, 2007)), and the degree to which an agent's effort influences the benchmark (referred to as acclimation by Koszegi and Rabin (2006, 2007)). Properties of culture affect agents' consideration of effort. Under the reference-dependent preferences of Koszegi and Rabin (2006, 2007), higher effort increases the likelihood of beating the agent's target (or reference point) as well as increasing the agent's reference point. The magnitudes of these two effects depend critically on the degree of acclimation, whereas the signs of these effects depend on the type of metric used. We present three general findings. First, organizations that rely on production metrics have incentives at least as strong as those relying on cost metrics. Second, the impact of acclimation depends critically on the type of metric used. Under cost metrics, higher acclimation leads to stronger incentives. Under production metrics, higher acclimation leads to weaker incentives. Third, the optimal culture is characterized by production metrics and unacclimating reference points, which we show have implications regarding organizational tenure policies. We conclude with a discussion of testable implications. We refer to the psychology literature and argue that production metrics are most likely to emerge when production is characterized by a high degree of uncertainty, such as in sales. Our model's main prediction is that in these types of environments, we would expect to have rapid production and low tenure in order to lower acclimation. In contrast, environments in which costs are more uncertain are more likely to have cost metrics, which favor longer tenure and loose deadlines in order to generate more acclimating reference points. The Precautionary Principle in Product Markets There any many differences between the U.S. and European regulation, but one notable difference concerns assessments of risk. U.S. and European regulation are concerned about different sources of risk and these sources of risk do not always overlap. As noted by Vogel (2003), U.S. regulation gives more consideration to risk concerning environmental harms, carcinogens in food, and endangered species, whereas European regulation emphasizes risks inherent in biotechnology and carbon emissions. In fact, to justify the regulation of biotechnology, Europeans give explicit emphasis to the Precautionary Principle: faced with an irreversible choice, it is better to presume significant harm. However, when it comes to carcinogens in food, Europeans are relatively more willing to bear the risks. In this paper, we use an agency setting to determine how regulators should manage the risks inherent in new products while not placing an undue burden on potential innovators. Faced with a product quality, they can adhere to the Precautionary Principle and presume harm. Alternatively, they can adhere to the Presumption of Innocence and presume the product is harmless. This paper analyzes which is better. There are two assumptions that separate our analysis from the literature. First, we consider a static framework in which no new information arises. Second, we assume that the equilibrium risk is endogenous. Entrepreneurs' can mitigate harm if given the appropriate incentives and their choices to mitigate harm will be influenced by the regulatory framework chosen by the regulators. We present three main findings. Under the extreme assumptions of risk neutral entrepreneurs, an absence of limited liability constraints, and low levels of potential harm, we show that either the Precautionary Principle or a Presumption of Innocence can achieve the first best outcome when faced with a product of uncertain quality. However, under less extreme assumptions, we identify two factors that favor an approach more consistent with the Precautionary Principle. First, if the dominant concern of the regulators is the limited liability constraint, then relying on the Precautionary Principle will best extract rent. Second, under larger levels of harm, the introduction of agency costs (either due to risk aversion or limited liability) will interact with dynamic complementarities. As the cost to incentivize risk mitigation increases, the equilibrium likelihood of severe harm will rise, and the principle will be more likely to prevent the product from coming to the market. Preventing the product from entering the market reduces the incentives to mitigate harm further. In our model, this dynamic complementarity can only exist when the potential harm is large enough that the product's net benefit to society may be negative.

This book was released on 2017-11-16 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to improve the understanding of human behavior that goes beyond monetary rewards. In particular, it investigates social influences in individual’s decision making in situations that involve coordination, competition, and deciding for others. Further, it compares how monetary and social outcomes are perceived. The common theme of all studies is uncertainty. The first four essays study individual decisions that have uncertain consequences, be it due to the actions of others or chance. The last essay, in turn, uses the advances in research on decision making under uncertainty to predict behavior in riskless choices. The first essay, Fairness Versus Efficiency: How Procedural Fairness Concerns Affect Coordination, investigates whether preferences for fair rules undermine the efficiency of coordination mechanisms that put some individuals at a disadvantage. The results from a laboratory experiment show that the existence of coordination mechanisms, such as action recommendations, increases efficiency, even if one party is strongly disadvantaged by the mechanism. Further, it is demonstrated that while individuals’ behavior does not depend on the fairness of the coordination mechanism, their beliefs about people’s behavior do. The second essay, Dishonesty and Competition. Evidence from a stiff competition environment, explores whether and how the possibility to behave dishonestly affects the willingness to compete and who the winner is in a competition between similarly skilled individuals. We do not find differences in competition entry between competitions in which dishonesty is possible and in which it is not. However, we find that due to the heterogeneity in propensity to behave dishonestly, around 20% of winners are not the best-performing individuals. This implies that the efficient allocation of resources cannot be ensured in a stiff competition in which behavior is unmonitored. The third essay, Tracing Risky Decision Making for Oneself and Others: The Role of Intuition and Deliberation, explores how individuals make choices under risk for themselves and on behalf of other people. The findings demonstrate that while there are no differences in preferences for taking risks when deciding for oneself and for others, individuals have greater decision error when choosing for other individuals. The differences in the decision error can be partly attributed to the differences in information processing; individuals employ more deliberative cognitive processing when deciding for themselves than when deciding for others. Conducting more information processing when deciding for others is related to the reduction in decision error. The fourth essay, The Effect of Decision Fatigue on Surgeons’ Clinical Decision Making, investigates how mental depletion, caused by a long session of decision making, affects surgeon’s decision to operate. Exploiting a natural experiment, we find that surgeons are less likely to schedule an operation for patients who have appointment late during the work shift than for patients who have appointment at the beginning of the work shift. Understanding how the quality of medical decisions depends on when the patient is seen is important for achieving both efficiency and fairness in health care, where long shifts are popular. The fifth essay, Preferences for Outcome Editing in Monetary and Social Contexts, compares whether individuals use the same rules for mental representation of monetary outcomes (e.g., purchases, expenses) as for social outcomes (e.g., having nice time with friends). Outcome editing is an operation in mental accounting that determines whether individuals prefer to first combine multiple outcomes before their evaluation (integration) or evaluate each outcome separately (segregation). I find that the majority of individuals express different preferences for outcome editing in the monetary context than in the social context. Further, while the results on the editing of monetary outcomes are consistent with theoretical predictions, no existing model can explain the editing of social outcomes.

Book excerpt: Using laboratory experiments as a tool, this dissertation contributes to the debate of decision making under risk three domains : The first essay presents the results of an experiment that elicits prudence and risk aversion. We find that the majority of subjects are prudent and that a big proportion is simultaneously prudent and risk averse, even if we find no correlation between prudence and risk aversion. The second essay investigates the effect of uncertainty on the decision to finance a public good. Our theoretical prediction is that risk adverse individuals will reduce their contributions to the production of a public good when facing more uncertainty. Results reveal that this prediction is confirmed but only for economists, and that non economists rather increase their contributions. In the last essay we elicit individual preferences over social risk. We analyze if these preferences are correlated with individual preferences over individual risk and over the well-being of others. We find that social risk attitudes closely approximate individual risk attitudes.

Book excerpt: Economic models require a formal treatment for individual preferences and expectations. Preferences are often assumed to be stable (and measurable) while expectations of the future are perfectly rational. Empirically, however, there is little evidence for stability of preferences or perfect rationality of expectations. This dissertation assesses the causes and consequences of these phenomena. The first two chapters identify novel channels leading to instability of revealed preferences in laboratory and field experiments, and the third chapter assesses the consequences of expectation bias on the outcome of policy in a general equilibrium model.

Book excerpt: ABSTRACT: I use economic experiments to investigate individual behavior under uncertainty. The first essay examines the consistency of risk preferences over two institutions. The two institutions I use are the first price sealed bid auction and a Holt-Laury lottery. There is some controversy as to whether or not observed overbidding in first price auction is actually caused by risk aversion or simply consistent with it. Behavior in the Holt-Laury lottery being caused by risk aversion is not in dispute. By having the same subjects participate in both institutions, I show that subjects' risk preferences in the lottery are consistent with subjects' risk preferences in the auction. This supports the notion that behavior in the first price sealed bid auction is in fact driven by risk aversion.

Available in PDF, EPUB and Kindle. Book excerpt: The need to understand the theories and applications of economic and finance risk has been clear to everyone since the financial crisis, and this collection of original essays proffers broad, high-level explanations of risk and uncertainty. The economics of risk and uncertainty is unlike most branches of economics in spanning from the individual decision-maker to the market (and indeed, social decisions), and ranging from purely theoretical analysis through individual experimentation, empirical analysis, and applied and policy decisions. It also has close and sometimes conflicting relationships with theoretical and applied statistics, and psychology. The aim of this volume is to provide an overview of diverse aspects of this field, ranging from classical and foundational work through current developments. Presents coherent summaries of risk and uncertainty that inform major areas in economics and finance Divides coverage between theoretical, empirical, and experimental findings Makes the economics of risk and uncertainty accessible to scholars in fields outside economics

This book was released on 2019 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of two lines of research. The first line focuses on decision making under uncertainty. Specifically, I analyze the nature of risk preferences in life-insurance choices, and I examine adverse selection and moral hazard in private-healthcare markets in a context where the government provides universal healthcare. The second line focuses on the political economy of institutions, and I study the impact of a multinational company on the economic development of its host country during and after its tenure. In Chapter 1, I estimate a structural model of risk preferences from the choice of insured amount in life-insurance contracts. The literature investigating life-insurance purchases has mostly focused on survey data to estimate how demand for insurance depends on demographic and socioeconomic factors, leaving aside the task of estimating an underlying model of decision making that generates this demand. Using proprietary data on life-insurance choices, I estimate a model of risky choice to explain households' decisions. My results indicate that, in addition to standard risk aversion (decreasing marginal utility for wealth), including decision weights that might differ from the actual probabilities improves the fit of the model. These weights can be interpreted as a combination of state-dependent utility and probability distortions. Moreover, I find support for the existence of heterogeneity in preferences. Women are more risk averse than men, and the decision weights vary depending on gender and age. In Chapter 2, we investigate adverse selection and moral hazard in private healthcare in markets where the government provides universal healthcare. We use proprietary data on health-insurance choices and medical expenditures to examine asymmetric information in this institutional setting. We disentangle adverse selection and moral hazard by leveraging variation in copays and deductibles implemented by the insurance company, and the fact that, for a sample of customers, the insured amount was exogenously assigned, shutting down the adverse selection channel. We find evidence for the presence of asymmetric information, both in the form of adverse selection and moral hazard. Moreover, we develop a model that incorporates sources of heterogeneity that could potentially explain selection in this institutional setting, namely risk aversion, risk type, concern for health, and taste for convenience services offered in the private healthcare sector. In Chapter 3, we analyze the impact of large-scale FDI on economic development by studying the case of the United Fruit Company (UFCo) in Costa Rica from 1889 to 1984. We implement a geographic regression discontinuity design that exploits a quasi-random assignment of land, and census data geo-referenced at the census-block level for 1973, 1984, 2000 and 2011. These allow us to identify the company's effect during its tenure, and after it stopped production. We find that former "UFCo lands" have had higher living standards and better economic outcomes than counterfactual areas without the company's presence, and that convergence is slow. These findings are validated using nighttime lights data. Detailed historical data suggest that the mechanisms behind our results are.

Available in PDF, EPUB and Kindle. Book excerpt: This Thesis, consisting of three chapters, studies the effects of uncertainty on decision-making with portfolio choice applications. Chapter 1 studies how experimental subjects report subjective probability distributions in the presence of ambiguity characterized by uncertainty over a fixed set of possible probability distributions generating future outcomes. The level of distribution uncertainty varies according to the observed outcomes and the rules used by the subjects to update the distribution uncertainty. This chapter introduces several reporting and updating rules and our empirical analysis focuses on estimating the sample distribution of these rules. Two dominant reporting rules emerge from our analysis: we find that 65% of subjects report distributions by properly weighting the possible distributions using their expressed uncertainty, while 22% of subjects report distributions close to the distribution they perceive as most likely. Further, we find significant heterogeneity in how subjects update their expressed uncertainty. On average, subjects tend to overweight the importance of their prior uncertainty relative to new information, leading to ambiguity that is substantially more persistent than would be predicted using Bayes' rule. Counterfactual simulations suggest that this persistence will likely hold in settings not covered by our experiment. Uncertainty in financial markets is a natural consequence of investors being unaware of objective probabilities of asset returns. Chapter 2 highlights that ambiguity and loss aversion have opposite effects on financial markets and can coexist in the presence of uncertainty. This chapter addresses the normative question of the optimal portfolio evaluation frequency for an investor in order to minimize the effect of myopia, but to learn about the investment opportunities in the market. Towards this end, we present a new experimental design in which investors are asked to make repeated portfolio choices facing initial ambiguity concerning the distribution of returns of one of the available assets. We exploit exogenous variations in evaluation frequency along with time variation of probabilistic beliefs over the possible return distributions to jointly identify ambiguity, loss, and risk aversion along with rules investors use to update their ambiguity. Estimates from a structural model suggest seven different classes of investors. Investor class membership depends on loss aversion, ambiguity aversion as well as risk aversion preferences. Further, we find that at the aggregated level, investors are loss averse, ambiguity averse and they display risk aversion over gains and risk seeking over losses. We conclude our analysis by using our model estimates to predict the distribution of optimal evaluation periods for our sample. Our predictions suggest that approximatively 70% of investors prefer the highest possible evaluation period frequency. Finally, Chapter 3 investigates whether or not the discount factor of the elderly affects their portfolio choices. We estimate time preferences using inter-temporal choice data from a hypothetical experiment in a representative sample of American elders and a structural model of decision-making accounting for lifetime uncertainty. Our results indicate considerable heterogeneity in the elderly population. Moreover, we find that older people who display a higher discount factor are more likely to own retirement accounts and risky assets. These older people also tend to decrease the share of financial wealth held in safe assets and increase the share of financial wealth held in risky assets. These findings suggest that time preferences affect investment choices from safe assets toward other financial assets, all else being equal.

Book excerpt: In this dissertation I focus on novel mechanisms for eliciting time and risk preferences and using these methods to test neoclassical and behavioral economic models. In Chapter 1, a new methodology for eliciting time preferences, the Convex Time Budget, is introduced. In Chapter 2, the Convex Time Budget is extended to explore the relationship between hyperbolic discounting and payment risk. In Chapter 3, a new measure of risk preferences, the Uncertainty Equivalent, is introduced and used to differentiate several models of risk preferences. In Chapter 4, I generate a new test distinguish between competing models of reference dependent preferences in risky choice.
