On preferences for being self-employed

The concept of procedural utility assumes that agents not only receive utility from outcomes but also attach an independent value to the procedures that lead to these outcomes. This paper analyzes whether the preferences that underlie procedural utility are homogeneous using the case of independence at the workplace. I exploit the event of German reunification to assign preferences for independence to respondents without using data on occupational choice or directly reported procedural preferences. I find that the self-employed report higher job satisfaction than the employed, even after controlling for income and hours worked. However, there is a significant amount of heterogeneity in this effect: while “independent types” experience a large increase in job satisfaction from being self-employed, the most “hierarchical types” could even experience a decrease.     

Utility from anticipation and personal equilibrium

I develop a dynamic model of individual decisionmaking in which the agent derives utility from physical outcomes as well as from rational beliefs about physical outcomes (“anticipation”), and these two payoff components can interact. Beliefs and behavior are jointly determined in a personal equilibrium by the requirement that behavior given past beliefs must be consistent with those beliefs. I explore three phenomena made possible by utility from anticipation, and prove that if the decisionmaker’s behavior is distinguishable from a person’s who cares only about physical outcomes, she must exhibit at least one of these phenomena. First, the decisionmaker can be prone to self-fulfilling expectations. Second, she might be time-inconsistent even if her preferences in all periods are identical. Third, she might exhibit informational preferences, where these preferences are intimately connected to her attitudes toward disappointments. Applications of the framework to reference-dependent preferences, impulsive behaviors, and emotionally difficult choices are discussed.

Author index for volume 26

The main result in revealed preference theory is that under fairly weak assumptions (strict concavity and monotonicity of the utility function), an agent's preferences can be recovered from the entire demand function. This paper addresses the possibility of recovering preferences from less extensive information, given additional maintained restrictions on preferences. Specifically, we explore whether an agent's utility function can be recovered from preferences over nominal gambles (when money is risky in real terms) or from demand for assets whose nominal returns contain common inflation or other risk. The recovery is constructive to the extent that there is a good numerical technique for doing Fourier transforms and inversions, and other numerical computations can be done.     

Exactly what happens after the Anscombe–Aumann race?

This paper derives a representation of preferences for a choice theory with vague environments; vague in the sense that the agent does not know the precise lotteries over outcomes conditional on states. Instead, he knows only a possible set of these lotteries for each state. Thus, this paper’s main departure from the standard subjective expected utility model is to relax an assumption about the environment, rather than weakening the axiomatic structure. My model is consistent with the behavior observed in the Ellsberg experiment. It can capture the same type of behavior as the multiple priors models, but can also result in behavior that is different from both the behavior implied by standard subjective expected utility models and the behavior implied by the multiple priors models.

Subjective expected utility theory with costly actions

This paper explores alternative axiomatizations of subjective expected utility theory for decision makers with direct preferences over actions; including a general subjective expected utility representation with action-dependent utility, and separately additive representations. In the context of the state-space formulation of agency theory, the results of this paper constitute axiomatic foundations of the agent's behavior.     

Probabilistic risk aversion with an arbitrary outcome set

This paper analyzes risk aversion when outcomes/consequences may not be measurable in monetary terms and people have fuzzy preferences over lotteries, i.e. they choose in a probabilistic manner. The paper shows that comparative risk aversion is well defined in a constant error/tremble model but not in a strong utility model.     

Epistemic Conditions for Equilibrium in Beliefs without Independence

Aumann and Brandenburger [Econometrica63(1995), 1161–1180.] provide sufficient conditions on the knowledge of the players in a game for their beliefs to constitute a Nash equilibrium. They assume, among other things, mutual knowledge of rationality. By rationality of a player, it is meant that the action chosen by him maximizes his expected utility, given his beliefs. There is, however, no need to restrict the notion of rationality to expected utility maximization. This paper shows that their result can be generalized to the case where players' preferences over uncertain outcomes belong to a large class of non-expected utility preferences.Journal of Economic LiteratureClassification Numbers: C72, D81.     

Subjective Expected Utility Theory with State-Dependent Preferences

This paper extends Savage′s subjective expected utility theory to include state-dependent preferences. The dependence of the decision maker′s preferences over consequences on the states of nature is represented by state-specific mappings of the set of consequences onto itself. Within this framework Savage′s postulates are reformulated and it is shown that there exist subjective expected utility representations of the preference relation over acts with unique, nonatomic, probability measure on the algebra of all events, and a state-dependent utility function over the set of consequences.

Loss aversion

Loss aversion is traditionally defined in the context of lotteries over monetary payoffs. This paper extends the notion of loss aversion to a more general setup where outcomes (consequences) may not be measurable in monetary terms and people may have fuzzy preferences over lotteries, i.e., they may choose in a probabilistic manner. The implications of loss aversion are discussed for expected utility theory and rank-dependent utility theory as well as for popular models of probabilistic choice such as the constant error/tremble model and a strong utility model (that includes the Fechner model of random errors and Luce choice model as special cases).     

Proper scoring rules for general decision models

If a decision maker whose behavior conforms to the max-min expected utility model is faced with a scoring rule for a subjective expected utility decision maker, she will always announce a probability belonging to her set of priors; moreover, for any prior in the set, there is a scoring rule inducing the agent to announce that prior. We also show that on the domain of Choquet expected utility preferences with risk neutral lottery evaluation and totally monotone capacities, proper scoring rules do not exist. This implies the non-existence of proper scoring rules for any larger class of preferences (CEU with convex capacities, multiple priors).     

利他偏好的内生模型及其经济学解释

利他行为对自利人性假设的挑战,要求经济学必须把偏好进行内生化处理。笔者首先构建了一个利他偏好内生模型,使得人类行为统一于效用最大化模式并具有了内在一致的规律性和可预测性;然后对利他偏好内生模型的合理性进行了解释。笔者认为,与利己行为不同,行为主体不是从利他行为后果而是从利他行为本身获得效用;通过整体间的生存适应性补偿机制,利他者不仅可以战胜利己者得以存在和持续,而且利他惩罚行为还为人类走出囚徒困境提供了有力的保证。     

Does Party Matter? An Historical Test Using Senate Tariff Votes in Three Institutional Settings

This article investigates the historical impact of party andconstituency preferences on tariff votes from the U.S. Senateover the period 1883–1930. We find that the estimatedeffect of party grows during periods in which legislative institutionsfavored strong parties. We conclude that party has a causaleffect on policy. If party serves solely as a proxy for unmeasuredcomponents of personal ideology or constituency preferences,then the estimated effect of party on policy outcomes shouldnot vary contemporaneously with changes in legislative institutions.But if party has an independent causal impact on policy outcomes,then changes in institutions favoring strong parties shouldlead to a greater effect of party on voting behavior, holdingconstituency preferences constant. Although our findings arelimited to votes over tariffs in the 19th and early 20th centuries,they suggest that further research into the mechanism by whichparty affects political decision making is important.     

The structure of consumer preferences,Federal Republic of Germany, 1950–1973

Summary The objective of this paper is to analyze the structure of consumer preferences and changes in preferences over time. Consumer preferences are represented by an indirect translog utility function with time-varying preferences that is quadratic in the logarithms of its arguments. We consider a system of demand functions associated with parameter restrictions consistent with the theory. We characterize groupwise separability and groupwise homotheticity of preferences and derive for each set of restrictions on preferences parametric restrictions on the corresponding system of demand functions. Empirical results of the tests, based on time series data for FRG consumption expenditures on three commodity groups — durables, non-durables, and energy — are presented.     

Utility in Case-Based Decision Theory

This paper provides two axiomatic derivations of a case-based decision rule. Each axiomatization shows that, if preference orders over available acts in various contexts satisfy certain consistency requirements, then these orders can be numerically represented by maximization of a similarity-weighted utility function. In each axiomatization, both the similarity function and the utility function are simultaneously derived from preferences, and the axiomatic derivation also suggests a way to elicit these theoretical concepts from in-principle observable preferences. The two axiomatizations differ in the type of decisions that they assume as data. Journal of Economic Literature Classification Number: D80.     

Imperfect memory and choice under risk

This paper presents a model of choice based on imperfect memory and self-deception. I assume that people have preferences over their own attributes (e.g., skill, knowledge, or competence) and can manipulate their memories. The model provides a prior-dependent theory of regret aversion and allows for prior-dependent information attitudes. It implies that behavior will converge to the one predicted by expected utility theory after a choice has been faced a sufficiently large number of times.     

Strategy-proof allocation mechanisms for pure public goods economies when preferences are monotonic

Summary. A fundamental problem in public finance is that of allocating a␣given budget to financing the provision of public goods (education, transportation, police, etc.). In this paper it is established that when␣admissible preferences are those representable by continuous and increasing utility functions, then strategy-proof allocation mechanisms whose (undominated) range contains three or more outcomes are dictatorial on the set of profiles of strictly increasing utility functions, a dense subset of the domain in the topologies commonly used in this context. If admissible utility functions are further restricted to be strictly increasing, or if mechanisms are required to be non-wasteful, then strategy-profness leads to (full) dictatorship.

Strategy-proof contract auctions and the role of ties

A contract auction establishes a contract between a center and one of the bidders. As contracts may describe many terms, preferences over contracts typically display indifferences. The Qualitative Vickrey Auction (QVA) selects the best contract for the winner that is at least as good for the center as any of the contracts offered by the non-winning players. When each bidder can always offer a contract with higher utility for the center at an arbitrarily small loss of her own utility, the QVA is the only mechanism that is individually rational, strategy-proof, selects stable outcomes, and is Pareto efficient. For general continuous utility functions, a variant of the QVA involving fixed tie-breaking is strategy-proof and also selects stable outcomes. However, there is no mechanism in this setting that in addition also selects Pareto efficient outcomes.     

Bargaining and Devolution in the Upper Guadiana Basin

Increasingly, central governments approach contentious natural resource allocation problems by devolving partial decision-making responsibility to local stakeholders. This paper conceptualizes devolution as a three-stage process and uses a simulation model calibrated to real-world conditions to analyze devolution in Spain’s Upper Guadiana Basin. The Spanish national government has proposed spending over a billion euros to reverse a 30 year decline in groundwater levels. We investigate how the government can most effectively allocate this money to improve water levels by utilizing its power to set the structure of a local negotiation process. Using a numerical Nash model of local bargaining, we find that if the national government creates appropriate incentives, local bargaining can produce water stabilization. The actual water levels that will emerge are highly dependent on the central government’s decisions about the budget available to local stakeholders and the default policy, which will be influenced by the relative value the government places on various financial and environmental outcomes. Our paper concludes by determining the relationship between these relative valuations and the government’s preferences over water levels.
