Abstract:  Financial constraints or economic needs, career development, psychological satisfaction as well as demographic and situational factors cause workers to seek more than one job while enjoying leisure time. In this paper we examine how a worker with prospect theory type of preferences allocates her time between leisure, a safe job and a risky job. Optimal time allocation for a sufficient loss averse worker depends on the reference level which in turn determines whether the worker is willing to experience relative losses or not. When the reference level is relatively low then the sufficiently loss averse worker will allocate some of her time to leisure and will hold both jobs in order to diversify risk and reduce income loss arising from the risky job. However, if the probability of a good state of nature is very high and the reference level is very low, the worker spends time only on leisure and the risky job while avoids the safe job. Loss aversion does not affect the optimal time allocation to the three activities as the time allocation results in avoiding relative losses for any state of nature. When the reference level is relative high, but not too high, the worker will allocate her time between both safe and risky jobs as well as to the leisure. Worker with very high reference level will avoid the safe job and will divide her time between the risky job and the leisure. In both cases the worker is willing to accept relative losses in the bad state of nature provided it is compensated with relative gains in the good state of nature. Here the allocation of time to the three activities depends on the degree of loss aversion. When the reference level is relatively low, but not too low, an increase in the reference level will reduce leisure time, reduce time in the risky job and increase time in the safe job. At very low reference levels, an increase in the reference level will result in the worker reallocating her time from leisure to the risky job assuming the probability of a good state of nature is higher than a threshold. When the reference level is high the opposite effects are observed. We also examine other comparative statics including the effect of changes in the wage rate.

Abstract:  Intertemporal choice experiments are increasingly implemented to make inference about discounting and marginal utility, yet little is known about the predictive power of resulting measures. This project links standard experimental choices to a decision on the desire to smooth a largestakes payment â€” around 10% of annual income â€” through time. In a sample of around 400 Guatemalan Conditional Cash Transfer recipients, we find that preferences over largestakes payment plans are closely predicted by experimental measures of patience and diminishing marginal utility. These represent the first findings in the literature on the predictive content of such experimentally elicited measures of discounting and marginal utility for a largestakes decision.

Abstract:  This work reports an online experiment with a generalpopulation sample examining the performance of budgetchoice tasks for elicitation of risk attitudes. First, I compare the investment task of Gneezy and Potters (1997) with the standard choicelist method of Holt and Laury (2002), and evaluate their performance in terms of the number of correctlypredicted binary decisions in a set of outofsample lottery choices. There are no significant differences between the tasks in this sense, and performance is modest. Second, I included three additional budgetchoice tasks (selection of a lottery from a linear budget set) where optimal decisions should have been corner solutions, and find that a large majority of participants provided interior solutions instead, casting doubts on subjects’ understanding of tasks of this type.

Abstract:  Obtaining significant levels of cooperation in public good and environmental games, under the assumption of players being purely selfish, is usually prevented by the problem of freeriding. Coalitions, in fact, generally fail to be internally stable and this cause a serious underprovision of the public good together with a significant welfare loss. The assumption of relational preferences, capable of better explaining economic behaviors in laboratory experiments, helps to foster cooperation, but, without opportune transfers scheme, no substantial improvements are reached. The present paper proposes an optimal transfers scheme under the assumption of players having Fehr and Schmidt (1999) utility functions, whose objective is to guarantee internal stability and to maximize the sum of utilities of coalition members. The transfers scheme is tested on a public good contribution game parameterized on the data provided by the RICE model and benchmarked with other popular transfers scheme in environmental economics. The proposed scheme outperforms its benchmarking counterparts in stabilizing coalitions and sensibly increases cooperation compared to the absence of transfers. Furthermore, for high but not extreme values of the parameter governing the intensity of disutility from disadvantageous inequality, it manages to support very large coalitions including three quarters of all players.

Abstract:  In situations where both the magnitude of gains and losses as well as the probability distribution over these realizations is uncertain, imprecision is an inherent feature of decisionmaking. While imprecision has been shown to affect individual valuations, many decisions are made in market settings with potentially different implications. We thus examine the impact of imprecision, first, in an individual decision task, and second, in experimental asset markets—with no imprecision (risk), imprecision in probabilities (ambiguity), imprecision in outcomes, and full imprecision. We find imprecision seeking in outcomes in people’s individual attitudes, but these preferences do not withstand market dynamics. Nevertheless, we observe imprecision aversion in probabilities at the end of trading, suggesting that ambiguity aversion, in contrast, prevails in experimental markets.

Abstract:  This paper studies a welfare maximization problem with heterogeneous agents. A social planner designs a menu of choices for agents who misperceive either the properties of options or their own preferences. When agents misperceive the true properties of alternatives, it is optimal to limit a menu when the probability of a mistaken choice is moderately high. Additionally, it could be optimal to construct the menu with more distinct alternatives. However, when agents misperceive their own tastes, it is optimal to limit choice only when agents choose randomly, and to propose alternatives that are more similar when there is a greater probability of agents making a mistake.

Abstract:  Theoretical papers show that optimal prevention decisions in the sense of selfprotection (i.e., primary prevention) depend not only on the level of (secondorder) risk aversion but also on higherorder risk preferences such as prudence (thirdorder risk aversion). We study empirically whether these theoretical results hold and whether prudent individuals show less preventive (selfprotection) effort than nonprudent individuals. We use a unique dataset that combines data on higherorder risk preferences and various measures of observed realworld prevention behavior. We find that prudent individuals indeed invest less in selfprotection as measured by influenza vaccination. This result is driven by high risk individuals such as individuals >60 years of age or chronically ill. We do not find a clear empirical relationship between riskpreferences and prevention in the sense of selfinsurance (i.e. secondary prevention). Neither risk aversion nor prudence is related to cancer screenings such as mammograms, Pap smears or Xrays of the lung.

Abstract:  This paper develops a new method informed by data and models to recover information about investor beliefs. Our approach uses information embedded in forwardlooking asset prices in conjunction with asset pricing models. We step back from presuming rational expectations and entertain potential belief distortions bounded by a statistical measure of discrepancy. Additionally, our method allows for the direct use of sparse survey evidence to make these bounds more informative. Within our framework, marketimplied beliefs may differ from those implied by rational expectations due to behavioral/psychological biases of investors, ambiguity aversion, or omitted permanent components to valuation. Formally, we represent evidence about investor beliefs using a novel nonlinear expectation function deduced using modelimplied moment conditions and bounds on statistical divergence. We illustrate our method with a prototypical example from macrofinance using asset market data to infer belief restrictions for macroeconomic growth rates.

Abstract:  This paper studies electoral competition over redistributive taxes between a safe incumbent and a risky opponent. As in prospect theory, economically disappointed voters bcome risk lovers, and hence are intrinsically attracted by the more risky candidate. We show that, after a large adverse economic shock, the equilibrium can display policy divergence: the more risky candidate proposes lower taxes and is supported by a coalition of very rich and very disappointed voters, while the safe candidate proposes higher taxes. This can explain why new populist parties are often supported by economically dissatisfied voters and yet they run on economic policy platforms of low redistribution. We show that survey data on the German SOEP are consistent with our theoretical predicions on voters' behavior.

Abstract:  The relation between biodiversity loss and frequency/probability of zoonose pandemic risk is now well documented in the literature. In this article we present a first model to integrate this phenomenon in the context of a general equilibrium dynamic economic setup. The occurrence of pandemic episodes is modeled as Poissonian leaps in stochastic economic variables. The planner can intervene in the economic and epidemiological dynamics in two ways: first (prevention), by deciding to preserve a greater quantity of biodiversity, thus decreasing the probability of a pandemic occurring, and second (mitigation), by reducing the death toll through a partial blockage of economic activity. The class of social welfare functional considered has, as polar cases, a total utilitarian and an average utilitarian specifications. It implicitly considers, at the same time, the effects of policies on mortality and on the productive capacity of the country. Thanks to the EpsteinZin specification of preferences, we can distinguish between risk aversion and fluctuation aversion. The model is explicitly solved and the optimal policy completely described. The qualitative dependence of the optimal intervention as a function of natural, productivity and preference parameters is discussed. In particular the optimal lockdown is shown to be more severe in societies valuing more human life, and the optimal biodiversity conservation is shown to be more relevant for more “forward looking” societies, with a small discount rate and a high degree of altruism towards individuals of future generations. We also show that societies accepting a large welfare loss to mitigate the pandemics are also societies doing a lot of prevention, not to have to incur the loss too often. After calibrating the model with COVID19 pandemic data we compare the mitigation efforts predicted by the model with those of the recent literature and we study the optimal preventionmitigation policy mix.

Abstract:  This paper constructs and estimates a householdlevel search model to analyze Roma spouses'utility maximization for leisure, home production, and work. The paper aims to explain labor market gender gaps in a marginalized Roma population with low labor market participation rates (males 53 percent and females 17 percent). The analysis uses data from the 2017 Regional Roma Survey for six Western Balkan countries. The simulation results show that the main source for gender differentials in the labor market is the unequal opportunities in favor of males  not gender preferences or differences in home production productivity. Therefore, most of the gender differences in the labor market can be closed by providing wives the same labor market conditions as husbands. Counterfactual policy experiments show that policies that increase the frequency of receiving a job offer, decrease the frequency of laying off workers, and reduce search increase Roma husbands'labor participation. Policies that equalize wages induces more wives to join the labor market and husbands to withdraw from it. This outcome signals that the wage gap is the dimension that deters the greatest number of Roma wives from joining the labor market.

Abstract:  We examine how the emergence of Covid19 in Wuhan, and the ramifications of associated events, influence prosociality, trust and attitudes towards risk and ambiguity. We assess these influences using an experiment consisting of financially incentivized economic tasks. We establish causality via the comparison of a baseline sample collected preepidemic with five sampling waves starting from the imposition of a stringent lock down in Wuhan and completed six weeks later. We find significant longterm increases  measured as the difference between the baseline and final wave average responses  in altruism, cooperation, trust and risk tolerance. Participants who remained in Wuhan during the lockdown exhibit lower trust and cooperation relative to other participants. We identify transitory effects from two events that permeated the public psyche. First, in the immediate aftermath of the Wuhan lockdown, there is a decrease in trust and an increase in ambiguity aversion. Second, the news of a highprofile whistleblower's death also decreases trust while heightening risk aversion.

Abstract:  Online firms deploy suites of software platforms, where each platform is designed to interact with users during a certain activity, such as browsing, chatting, socializing, emailing, driving, etc. The economic and incentive structure of this exchange, as well as its algorithmic nature, have not been explored to our knowledge; we initiate their study in this paper. We model this interaction as a Stackelberg game between a Designer and one or more Agents. We model an Agent as a Markov chain whose states are activities; we assume that the Agent's utility is a linear function of the steadystate distribution of this chain. The Designer may design a platform for each of these activities/states; if a platform is adopted by the Agent, the transition probabilities of the Markov chain are affected, and so is the objective of the Agent. The Designer's utility is a linear function of the steady state probabilities of the accessible states (that is, the ones for which the platform has been adopted), minus the development cost of the platforms. The underlying optimization problem of the Agent  that is, how to choose the states for which to adopt the platform  is an MDP. If this MDP has a simple yet plausible structure (the transition probabilities from one state to another only depend on the target state and the recurrent probability of the current state) the Agent's problem can be solved by a greedy algorithm. The Designer's optimization problem (designing a custom suite for the Agent so as to optimize, through the Agent's optimum reaction, the Designer's revenue), while NPhard, has an FPTAS. These results generalize, under mild additional assumptions, from a single Agent to a distribution of Agents with finite support. The Designer's optimization problem has abysmal "price of robustness", suggesting that learning the parameters of the problem is crucial for the Designer.

Abstract:  This paper estimates the effect of the European Central Banks’s monetary policy on the term structure of expected stock market risk premia. Expected stock market premia are solved using analysts’ dividend forecasts, the Eurostoxx 50 stock index and Eurostoxx 50 dividend futures. Although riskfree rates have decreased after the global financial crisis, the results indicate that the expected average stock market return has remained quite stable at around 9 percent. This implies that the expected average stock market risk premium has increased since the financial crisis. The effect of monetary policy on expected premia is analysed using VAR models and local projection methods. According to the results, monetary policy easing raises the average expected premium. The effect is explained by a rise in longhorizon expected premia.

Abstract:  When Luce (1959) introduced his Choice Axiom, this raised immediate criticism by Debreu (1960), pointing out inconsistencies when items are ranked from inferior to superior (instead of ranking them from superior to inferior). As recently shown by Breitmoser (2019), Luce’s Independence of Irrelevant Alternatives (IIA) is equivalent to Luce’s Choice Axiom when positivity holds. This fact seems to have escaped attention so far and might suggest that Debreu’s critique also applies to the notion of IIA, which is widely used in the literature. Furthermore, this notion could potentially be intuitively misleading, as the consequences of this axiom seem to be different than the name suggests. This might spill over to the intuitive interpretation of theoretical results that build on this axiom. This paper motivates the introduction of the notion of Independece of Alternatives (IoA) in the context of ranking models. IoA postulates a property of independence which seems intuitively reasonable (as it exactly captures what Luce himself describes when speaking about IIA), but does not exclusively hold in models where Luce’s Choice Axiom applies. Assuming IoA, expected ranks in the ranking of multiple alternatives can be determined from pairwise comparisons. The result holds in many models which do not satisfy IIA (e.g. certain Thurstone V models, Thurstone (1927)), can significantly simplify the calculation of expected ranks in practice and potentially facilitate analytic methods that build on more general approaches to model the ranking of multiple alternatives.

Abstract:  We use a novel method to elicit and measure higher order risk preferences (prudence and temperance) in an experiment with 658 adolescents. In line with theoretical predictions, we find that higher order risk preferences particularly prudence are strongly related to adolescents' field behavior, including their financial decision making, ecofriendly behavior, and health status, including addictive behavior. Most importantly, we show that dropping prudence and temperance from the analysis of students' field behavior would yield largely misleading conclusions about the relation of risk aversion to these domains of field behavior. Thus our paper puts previous work that ignored higher order risk preferences into an encompassing perspective and clarifies which orders of risk preferences can help understand field behavior of adolescents.

Abstract:  This paper illustrates a challenge in analyzing the learning algorithms resulting in secondorder difference equations. We show in a simple monetary model that the learning dynamics do not converge to the rational expectations monetary steady state. We then show that to guarantee convergence, the gain parameter used in the learning rule has to be restricted based on economic fundamentals in the monetary model.

Abstract:  We study pollution cleanup in the Ganges in Varanasi, India. Voters elect politicians and elected politicians decide how much pollution to clean up. Between the two time periods, there is an election. Politicians are sincere or insincere. The marginal cost of public funds ζ measures how efficiently elected politicians transform tax receipts into pollution cleanup. Voters have identical per period utility functions. We ascertain the equilibrium outcome and per period voter welfare. Second, we show that an increase in ζ reduces the equilibrium pollution cleanup and voter welfare. Third, an insincere politician can delay the revelation of his insincerity. We show that a critical value of ζ,ζ^*, exists such that the insincere incumbent separates and loses the election if and only if ζ>ζ^* and that he pools and is reelected otherwise. Finally, we note that an increase in ζ can raise voter welfare when politicians are more likely to be insincere.

Abstract:  Based on results discussed by Meinhardt (2013), which presents a dual characterization of the prekernel by a finite union of solution sets of a family of quadratic and convex objective functions, we could derive some results related to the singlevaluedness of the prekernel. Rather than extending the knowledge of game classes for which the prekernel consists of a single point, we apply a different approach. We select a game from an arbitrary game class with a single prekernel element satisfying the nonempty interior condition of a payoff equivalence class, and then establish that the set of related and linear independent games which are derived from this prekernel point of the default game replicates this point also as its sole prekernel element. Hence, a bargaining outcome related to this prekernel element is stable. Furthermore, we establish that on the restricted subset on the game space that is constituted by the convex hull of the default and the set of related games, the prekernel correspondence is singlevalued, and therefore continuous. In addition, we provide sufficient conditions that preserve the prenucleolus property for related games even when the default game has not a single prekernel point. Finally, we apply the same techniques to related solutions of the prekernel, namely the modiclus and antiprekernel, to work out replication results for them.

Abstract:  The topics treated in this thesis are inherently twofold. The first part considers the problem of a market maker optimally setting bid/ask quotes over a finite time horizon, to maximize her expected utility. The intensities of the orders she receives depend not only on the spreads she quotes, but also on unobservable factors modelled by a hidden Markov chain. This stochastic control problem under partial information is solved by means of stochastic filtering, control and PDMPs theory. The value function is characterized as the unique continuous viscosity solution of its dynamic programming equation and numerically compared with its full information counterpart. The optimal full information spreads are shown to be biased when the exact market regime is unknown, as the market maker needs to adjust for additional regime uncertainty in terms of PnL sensitivity and observable order flow volatility. The second part deals with numerically solving nonzerosum stochastic impulse control games. These offer a realistic and farreaching modelling framework, but the difficulty in solving such problems has hindered their proliferation. A policyiterationtype solver is proposed to solve an underlying system of quasivariational inequalities, and it is validated numerically with reassuring results. Eventually, the focus is put on games with a symmetric structure and an improved algorithm is put forward. A rigorous convergence analysis is undertaken with natural assumptions on the players strategies, which admit graphtheoretic interpretations in the context of weakly chained diagonally dominant matrices. The algorithm is used to compute with high precision equilibrium payoffs and Nash equilibria of otherwise too challenging problems, and even some for which results go beyond the scope of the currently available theory.

Abstract:  Previous research on educational aspirations and educational decisionmaking has mostly focused on highincome countries and thus on a relatively homogeneous socioeconomic context. However, educational decisionmaking may be sensitive to contextual factors such as economic deprivation, a dysfunctional welfare state or poor access to credit markets – characteristics shared by most low and middleincome countries. To better understand how economically disadvantaged individuals in developing countries make their educational choices, we conducted a survey based on a random sample with high school students in the rural department Morazán in El Salvador, a lower middleincome country in Latin America. Our results show that regardless of the social background, almost all students aspire to pursue tertiary education, probably due to the high tertiary degree premium in earnings and the high social benefits. However, the lack of possibilities to finance their studies generally prevents the realisation of these aspirations for lower social background students. While in highincome countries, cost factors are not very important in the decisionmaking process, the burden of costs explains around 45 percent of the social background effect in El Salvador. Other factors such as academic confidence, expected future economic benefits, parental status maintenance wish, individual risk aversion and time discounting preferences play only a minor role.

Abstract:  We take a refreshing new look at boundedly rational quadratic models in economics using some elementary modeling of the principles put forward in the book Humanomics by Vernon L. Smith and Bart J. Wilson. A simple model is introduced built on the fundamental Humanomics principles of gratitude/resentment felt and the corresponding action responses of reward /punishment in the form of higher/lower payo transfers. There are two timescales: one for strictly selfinterested action, as in economic equilibrium, and another governed by feelings of gratitude/resentment. One of three timescale scenarios is investigated: one where gratitude /resentment changes much more slowly than economic equilibrium (â€œquenched modelâ€ ). Another model, in which economic equilibrium occurs over a much slower time than gratitude /resentment evolution (â€œannealedâ€ model) is set up, but not investigated. The quenched model with homogeneous interactions turns out to be a nonfrustrated spinglass model. A twoagent quenched model with heterogeneous aligning (ferromagnetic) interactions is analyzed and yields new insights into the critical quenched probability p (1 ô€€€ p) that represents the empirical frequency of opportunity for agent i to take action for the benefit (hurt) of other that invokes mutual gratitude (resentment). A critical quenched probability p i , i = 1; 2, exists for each agent. When p p i , agent i will take action sensitive to their interpersonal feelings of gratitude/resentment and thus reward/punish the initiating benefit/hurt. We find that the p i are greater than onehalf, which implies agents are averse to resentful behavior and punishment. This was not built into the model, but is a result of its properties, and consistent with Axiom 4 in Humanomics about the asymmetry of gratitude and resentment. Furthermore, the agent who receives less payo is more averse to resentful behavior; i.e., has a higher critical quenched probability. For this particular model, the Nash equilibrium has no predictive power of Humanomics properties since the rewards are the same for selfinterested behavior, resentful behavior, and gratitude behavior. Accordingly, we see that the boundedly rational Gibbs equilibrium does indeed lead to richer properties.
