Lewis ascribes the stubborn persistence of addictions to habit, itself a normal process that does not imply lack of responsiveness to motivation. However, he suggests that more dynamic processes may be involved, for instance that “our recurrently focused brains inevitably self-organize.” Given hyperbolic delay discounting, a reward-seeking internal marketplace model describes two processes, also normal in themselves, that may give rise to the “deep attachment” to addictive activities that he describes: People learn to interpret current choices as test cases for (...) how they can expect to choose in the future, thus recruiting additional incentive against a universal tendency to temporarily prefer smaller, sooner to larger, later rewards. However, when this incentive is not enough, the same interpretation creates incentive to abandon the failed area, leading to the abstinence violation effect and a localized weak will. Normal human value does not come entirely, or even mainly, from expectation of external rewards, but is generated endogenously in imagination. Hyperbolic discounting provides an account of how we learn to cultivate the hedonic importance of occasions for endogenous reward by building appetite. In this account, expectations of the far future have to be rewarded endogenously if they are be as important as currently rewarded alternatives; and this importance is prone to collapse. Both will and hedonic importance are recursive and thus hard to study by controlled experiment, but do represent modelable, reward-based hypotheses about the dynamic nature of habit. (shrink)

To the extent that acting fairly is in an individual's long-term interest, short-term impulses to cheat present a self-control problem. The only effective solution is to interpret the problem as a variant of repeated prisoner's dilemma, with each choice as a test case predicting future choices. Moral choice appears to be the product of a contract because it comes from self-enforcing intertemporal cooperation.

Although Ainslie rejects cognitivism as providing an explanation of willpower, a type of nonhomuncular cognitivism is hiding in his own proposal. The key mental mechanism of aggregating individual decisions (bundled reframings) involves representation and decoupling operations encompassed within the analytic system of dual-process mental architectures.

A climate that is too cold to grow crops for part of the year demands foresight and self-control skills. To the extent that a culture has developed intertemporal bargaining, its members will have more autonomy, but pay the cost of being more compulsive, than members of societies that have not. Monetary resources will be a consequence but will also be fed back as a cause.

Intertemporal bargaining theory based on the hyperbolic discounting of expected rewards accounts for how choosing in categories increases self-control, without postulating, as Rachlin does, the additional rewardingness of patterns per se. However, altruism does not seem to be based on self-control, but on the primary rewardingness of vicarious experience. We describe a mechanism that integrates vicarious experience with other goods of limited availability.

An intertemporal bargaining model of commitment does not entail the interaction of parts within the person as Rachlin claims, and is needed to explain properties of self-control that his molar generalization model does not predict.

The models of internal self-control that have recently been proposed by behavioral economists do not depict motivational interaction that occurs while temptation is present. Those models that include willpower at all either envision a faculty with a motivation (“strength”) different from the motives that are weighed in the marketplace of choice, or rely on incompatible goals among diverse brain centers. Both assumptions are questionable, but these models’ biggest problem is that they do not let resolutions withstand re-examination while being challenged (...) by impulsive alternatives. The economists’ models all attempt to make a single equilibrium preference predictable from a person’s prior incentives. This was the original purpose of these models’ hyperboloid (“β–δ”) delay discount functions, which have been widely justified by the assumption that a person’s intertemporal inconsistency (impulsiveness) can be accounted for by the arousal of appetite for visceral rewards. Although arousal is clearly a factor in some cases of intertemporal inconsistency, it cannot be blamed for others, and furthermore does not necessarily imply hyperboloid discounting. The inadequacy of β–δ functions is particularly evident in models of internal self-control. I have reviewed several of these models, and have argued for a return to pure hyperbolic discount function as originally proposed, the relatively high tails of which can motivate a recursive process of self-prediction and thereby the formation of self-enforcing intertemporal contracts. Such a process does not require a separately motivated faculty of will, or incompatible goals among brain centers; but it also does not permit the prediction of unique preferences from prior incentives.

Behavioral science has long been puzzled by the experience of temptation, the resulting impulsiveness, and the variably successful control of this impulsiveness. In conventional theories, a governing faculty like the ego evaluates future choices consistently over time, discounting their value for delay exponentially, that is, by a constant rate; impulses arise when this ego is confronted by a conditioned appetite. Breakdown of Will presents evidence that contradicts this model. Both people and nonhuman animals spontaneously discount the value of expected events (...) in a curve where value is divided approximately by expected delay, a hyperbolic form that is more bowed than the rational, exponential curve. With hyperbolic discounting, options that pay off quickly will be temporarily preferred to richer but slower-paying alternatives, a phenomenon that, over periods from minutes to days, can account for impulsive behaviors, and over periods of fractional seconds can account for involuntary behaviors. Contradictory reward-getting processes can in effect bargain with each other, and stable preferences can be established by the perception of recurrent choices as test cases in recurrent intertemporal prisoner's dilemmas. The resulting motivational pattern resembles traditional descriptions of the will, as well as of compulsive phenomena that can now be seen as side-effects of will: over-concern with precedent, intractable but circumscribed failures of self-control, a motivated unconscious, and an inability to exploit emotional rewards. Hyperbolic curves also suggest a means of reducing classical conditioning to motivated choice, the last necessary step for modeling many involuntary processes like emotion and appetite as reward-seeking behaviors; such modeling, in turn, provides a rationale for empathic reward and the “construction” of reality. Key Words: altruism ; appetite; behavioral economics; classical conditioning; compulsions; dynamic inconsistency; emotions; empathy; freedom of will; hyperbolic discounting; impulsiveness; intertemporal bargaining; self-control; social construction; volition; weakness of will.

Departing from Bourdieu's collective habitus, this essay develops a theory of the subjectivity of habitus, meaning the social-psychological processes comprising the agent and fueling deliberation. By incorporating George Ainslie's theory of the will and deliberation as the intertemporal bargaining of a population of interests, I theorize the “saturated agent” composed of an economy of interests, analogous to Bourdieu's “economy of practices” invested and saturated with cultural capital. Here culturally saturated interests negotiate strategically within the agent, with the ending (...) balance constituting the habitus. Additionally, reflexivity becomes amenable to habitus as “desaturation” or suspending the commitment to a set of culturally saturated interests as a result of a crisis, followed by “resaturation”, the restructuring of the economy of interests.

Most authors who discuss willpower assume that everyone knows what it is, but our assumptions differ to such an extent that we talk past each other. We agree that willpower is the psychological function that resists temptations – variously known as impulses, addictions, or bad habits; that it operates simultaneously with temptations, without prior commitment; and that use of it is limited by its cost, commonly called effort, as well as by the person's skill at executive functioning. However, accounts are (...) usually not clear about how motivation functions during the application of willpower, or how motivation is related to effort. Some accounts depict willpower as the perceiving or formation of motivational contingencies that outweigh the temptation, and some depict it as a continuous use of mechanisms that interfere with re-weighing the temptation. Some others now suggest that impulse control can bypass motivation altogether, although they refer to this route as habit rather than willpower.It is argued here that willpower should be recognized as either or both of two distinct functions, which can be calledresolveandsuppression. Resolve is based on interpretation of a current choice as a test case for a broader set of future choices, which puts at stake more than the outcome of the current choice. Suppression is inhibiting valuation of (modulating) and/or keeping attention from (filtering) immediate alternatives to a current intention. Perception of current choices as test cases for broader outcomes may result in reliable preference for these outcomes, which is experienced as an effortlesshabit– a successful result of resolve, not an alternative method of self-control. Some possible brain imaging correlates are reviewed. (shrink)

Ainslie’s contribution offers a useful refinement of his powerful model of intertemporal bargaining. However, he focuses mostly on the cognitive mechanisms of choice. I suggest that these interact with emotional, personality, and developmental dynamics that cannot be ignored, either psychologically or neurally.

The matching law accounts for both addictive behavior and the usefulness of a person's evaluating choices in overall categories. To explain why overall bookkeeping, once learned, does not easily win out over local bookkeeping, another implication of matching is needed: intertemporal bargaining. The role of melioration, though probably important for new addiction is separate.

Ainslie identifies two possible motivational sources for resolve: “thinking categorically” and “intertemporal bargaining.” Ainslie opts for intertemporal bargaining, adding that thinking categorically has no motivational power. The most researched instance of willpower is remission from addiction. This literature shows that aspirations for a more desirable identity and comfortable lifestyle motivate remission. In other words, “thinking categorically” drives willpower.

The will has generated a wider range of opinions than most phenomena, lacking as it does both an animal model and consistent behavioral correlates. It has even been held not to exist. The commentators approached my intertemporal bargaining (picoeconomic) model from many angles. Doubts about the existence of the underlying phenomenon, hyperbolic discounting, were still raised by some, but other commentators added to the evidence for it, which I regard now as overwhelming. Where mechanisms of self-control were specified, (...) I found it possible to place them within a picoeconomic framework. (shrink)

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

One prevalent type of slippery slope argument has the following form: (1) by doing some initial act now, we will bring it about that we subsequently do some more extreme version of this act, and (2) we should not bring it about that we do this further act, therefore (3) we should not do the initial act. Such arguments are frequently regarded as mistaken, often on the grounds that they rely on speculative or insufficiently strong empirical premises. In this article (...) I point out another location at which these arguments may go wrong: I argue that, in their standard form, the truth of their empirical premises constitutes evidence for the falsity of their normative premises. If we will, as predicted, do the further act in the future, this gives us at least a prima facie reason to believe that the performance of this further act would be good, and thus something we should try to bring about. I end by briefly assessing the dialectic implications of my argument. I delineate a subset of slippery slope arguments against which my objection may be decisive, consider how the proponents of such arguments may evade my objection by adding further premises, and examine the likely plausibility of these additional premises.

The problem of intertemporal choice arises when outcomes are received in different moments of time. This paper presents an axiomatic model of intertemporal choice when consumption in the previous moment of time contributes to utility evaluation of consumption in the current moment. This model generalizes classic discounted utility theory (also known as constant or exponential discounting) in two ways. First, in every moment of time, a decision maker derives utility not only from current consumption but also from “residual” (...) consumption in the previous moment of time. Second, these utilities are discounted with weights that are essentially a quasi-hyperbolic discounting function. The paper presents an application of the proposed model to the problem of optimal consumption and savings given a fixed income (wealth). When a decision maker derives satisfaction from both instantaneous consumption as well as a share of consumption in the previous moment of time, optimal consumption path is cyclic—periods of relatively high consumption are interchanged with periods of relatively low consumption. These cycles decay over time. Asymptotically, the consumption path exhibits conventional properties (constant, increasing or decreasing over time when a gross interest rate multiplied by discount factor is correspondingly equal to, greater than, or less than one).

From a traditional moral point of view, business practitioners often seem overly concerned about the behavior of their peers in deciding how they ought to act. We propose to account for this concern by introducing a mutual trust perspective, where moral obligations are grounded in a sense of trust that others will abide by the same rules. when grounds for trust are absent, the obligation is weakened. We illustrate this perspective by examining the widespread ambivalence with regard to deception about (...) one's settlement preferences in negotiation. On an abstract level, such deception generally seems undesirable, though in many individual cases it is condoned, even admired as shrewd bargaining. Because of the difficulty in verifying someone's settlement preferences, it is hard to establish a basis for trusting the revelations of the other party, especially in competitive negotiations with relative strangers.

Climate negotiations under the United Nations Framework Convention on Climate Change have so far failed to achieve a robust international agreement to reduce greenhouse gas emissions. Game theory has been used to investigate possible climate negotiation solutions and strategies for accomplishing them. Negotiations have been primarily modelled as public goods games such as the Prisoner’s Dilemma, though coordination games or games of conflict have also been used. Many of these models have solutions, in the form of equilibria, corresponding to possible (...) positive outcomes—that is, agreements with the requisite emissions reduction commitments. Other work on large-scale social dilemmas suggests that it should be possible to resolve the climate problem. It therefore seems that equilibrium selection may be a barrier to successful negotiations. Here we use an N-player bargaining game in an agent-based model with learning dynamics to examine the past failures of and future prospects for a robust international climate agreement. The model suggests reasons why the desirable solutions identified in previous game-theoretic models have not yet been accomplished in practice and what mechanisms might be used to achieve these solutions.

Prevailing literature argues that arguing is the only appropriate mode of deliberation. The literature acknowledges bargaining, story telling, and other forms of communication, but is unwilling to describe these as deliberation, properly speaking. The claim is that describing them as such would amount to concept stretching. In this article I argue that arguing exhausts neither the legitimate modes of deliberation nor the modes for effective deliberation. To do this I delineate two basic categories of issues we normally deliberate upon, (...) and demonstrate that arguing is more appropriate for one category, not so appropriate for the other. (shrink)

Recently, philosophers have investigated the emergence and evolution of the social contract. Yet extant work is limited as it focuses on the use of simple behavioral norms in rather rigid strategic settings. Drawing on axiomatic bargaining theory, we explore the dynamics of more sophisticated norms capable of guiding behavior in a wide range of scenarios. Overall, our investigation suggests the utilitarian bargaining solution has a privileged status as it has certain stability properties other social arrangements lack.

This article argues that systematic comparative analyses of women's strategies and coping mechanisms lead to a more culturally and temporally grounded understanding of patriarchal systems than the unqualified, abstract notion of patriarchy encountered in contemporary feminist theory. Women strategize within a set of concrete constraints, which I identify as patriarchal bargains. Different forms of patriarchy present women with distinct “rules of the game” and call for different strategies to maximize security and optimize life options with varying potential for active or (...) passive resistance in the face of oppression. Two systems of male dominance are contrasted: the sub-Saharan African pattern, in which the insecurities of polygyny are matched with areas of relative autonomy for women, and classic patriarchy, which is characteristic of South and East Asia as well as the Muslim Middle East. The article ends with an analysis of the conditions leading to the breakdown and transformation of patriarchal bargains and their implications for women's consciousness and struggles. (shrink)

Traumatic brain injuries to the frontal lobes are associated with many maladaptive forms of behavior. We investigated the association between brain damage and impulsivity, as measured by the rate of delay discounting. The main aim of this study was to test the hypothesis of steeper discounting of different amounts in a group of patients with frontal lobe damage. We used a delay discounting task in the form of a structured interview. A total of 117 participants were divided into five groups: (...) three neurological groups and two groups without brain damage. Our analyses showed that patients with focal damage to the frontal lobes demonstrated steeper delay discounting than other participants. Other clinical groups demonstrated similar discounting rates. The data pattern related to the magnitude effect on the group level suggested that the magnitude effect is absent in the group of patients with damage to the frontal lobes; however, results were less consistent on an individual level. Amount-dependent discounting was observed in only two groups, the healthy control group and the neurological group with other cortical areas damaged. (shrink)

This paper axiomatizes a recursive utility model that captures both intertemporal utility smoothing defined across time and ambiguity aversion defined over states. The resulting representation adapts Wakai model of intertemporal utility smoothing as an aggregator function, where the utility of the certainty equivalent of future uncertainty is computed by Gilboa and Schmeidler multiple-priors utility. The model also permits the separation of intertemporal utility smoothing from ambiguity aversion.

This paper considers the simple two-person two-period case of distributive judgement, and argues (a) that sensible intertemporal distributive principle should consider both the distribution of people's life time well-being and the distribution of people's well-being at each period and (b) that, if (a) is correct, Egalitarianism is more acceptable than Prioritarianism since the latter must choose either one.

Nick Bostrom and others have suggested treating decision-making under moral uncertainty as analogous to parliamentary decision-making. The core suggestion of this “parliamentary approach” is that the competing moral theories function like delegates to the parliament, and that these delegates then make decisions by some combination of bargaining and voting. There seems some reason to hope that such an approach might avoid standard objections to existing approaches (for example, the “maximise expected choiceworthiness” (MEC) and “my favourite theory” approaches). However, the (...) parliamentary approach is so far extremely underspecified, making it largely indeterminate how such a model will in fact behave in the respects that those concerned with moral uncertainty care about. This paper explores one way of making it precise. We treat predicaments of moral uncertainty as analogous to bargaining situations alone (setting aside voting), and apply a version of the Nash solution that is standard in bargaining theory. The resulting model does indeed perform in many of the hoped-for ways. However, so also does a version of MEC that employs a structural approach to intertheoretic comparisons. It seems to us an open question which, regarding this version of MEC and the bargaining-theoretic approach, is superior to the other. We identify the key points on which the two differ. (shrink)

Several areas of welfare economics seek to evaluate states of affairs as a function of interpersonally comparable individual utilities. The aim is to map each state of affairs onto a vector of individual utilities, and then to produce an ordering of these vectors that can be represented by a mathematical function assigning a real number to each. When this approach is used in intertemporal contexts, a central theoretical question concerns the evaluative weight to be applied to utility coming at (...) different times. This question concerns the rate of pure time preference, which is one key determinant of the social discount rate. This article argues that the standard philosophical account of pure time preference is mistaken, because it ascribes to economists a methodological commitment they need not, and often do not, accept. This in turn undercuts the most common philosophical objection to pure time preference, which traces at least to Rawls’s A Theory of Justice. The article then evaluates three further objections to pure time preference, concluding that it might still be defensible under certain circumstances. The article closes by articulating a final argument that is suggested by the “Social, Economic and Ethical Concepts and Methods” chapter of the most recent Intergovernmental Panel on Climate Change report. If this further argument is sound, it would constitute a decisive objection to pure time preference as it currently figures in much intertemporal welfare economics. (shrink)

The question of what a group of rational agents would agree on were they to deliberate on how to organise society is central to all hypothetical social contract theories. If morality is to be based on a social contract, we need to know the terms of this contract. One type of social contract theory, contractarianism, aims to derive morality from rationality alone. Contractarians need to show, amongst other things, that rational and self-interested individuals would agree on an impartial division of (...) a cooperative surplus. But it is often claimed that contractarians cannot show this without introducing moral assumptions. This paper argues that on the right understanding of the question contractarians are asking, these worries can be answered. Without relying on moral assumptions, the paper offers a novel derivation of symmetry, which is the axiom responsible for the impartiality of the most famous economic bargaining solutions appealed to by contractarians.

In this paper we deal with the extension of Nash bargaining theory to nonconvex problems. By focussing on the Social Welfare Ordering associated with a bargaining solution, we characterize the symmetric Nash Bargaining Solution (NBS). Moreover, we obtain a unified method of proof of recent characterization results for the asymmetric single-valued NBS and the symmetric multivalued NBS, as well as their extensions to different domains.

Evolutionary accounts of morality consider behavior in rather simple scenarios. Evolutionary work on fairness focuses on the division of a windfall and, importantly, assumes that the positions of those involved are entirely symmetric. I consider more complicated strategic settings and find that there is a strong tendency for evolution to produce divisions consistent with the so-called Nash bargaining solution. I also uncover the evolutionary importance of comprehensiveness, an often-overlooked feature of division problems.

Does the “free market” foster more freedom for individuals generally and less coercion? Libertarians and other market advocates argue that the unfettered market maximizes freedom and hence has less coercion than any feasible alternative.

Both supporters and critics agree that coercion undermines freedom and that that is what is ultimately prima facie wrong with it. Further, they agree that the extent to (...) which an economic system includes coercion provides a serious strike against it. The problem is that there is little consensus on the necessary conditions for coercion. In this paper I will be concerned with the nature of coercive relationships in the market. Market interactions have a particular character and occur within a specific institutional framework. Other accounts of coercion have failed to capture the unique character of coercion in the market because they have failed to take into account certain nontrivial facts about the market which are essential to the analysis of coercive market relations.

In this paper we examine the merit of bargaining theory, in its economic and ecological forms, as a model for understanding variation in the frequency of participation in cooperative fishing among men of Ifaluk atoll in Micronesia. Two determinants of bargaining power are considered: resource control and a bargainer’s utility gain for his expected share of the negotiated resource. Several hypotheses which relte cultural and life-course parameters to bargaining power are tested against data on the frequency of (...) cooperative sail-fishing participation. Consistent with predictions generated from bargaining theory, we show that (1) age is negatively correlated with cooperative fishing participation, (2) men of highranking clans and men with high levels of education fish less than men of low-ranking clans and less-educated men, (3) men with high expected utility gains from fishing returns fish more than men with low expected utility gains, (4) number of dependents is positively correlated with cooperative fishing participation, and (5) the number of young genetic offspring residing with a man is positively correlated with cooperative fishing participation, whereas the number of genetic offspring more than 13 years old who are residing with a man is negatively correlated with cooperative fishing participation.

Teleosemantics is the view that mental content depends on etiological function. Moral adaptationism is the view that human morality is an evolved adaptation. Jointly, these two views offer new venues for naturalist metaethics. Several authors have seen, in the conjunction of these views, the promise of assigning naturalistically respectable descriptive content to moral judgments. One such author is Neil Sinclair, who has offered a blueprint for how to conduct teleosemantic metaethics with the help of moral adaptationism. In this paper, I (...) argue that the prospects for assigning descriptive content to moral judgments on the basis of teleosemantics are bad. I develop my argument in dialogue with Sinclair’s paper and argue that, although Sinclair’s account of the evolution of morality is plausible, the teleosemantic account of the descriptive content of moral judgments which he bases thereon suffers from crucial shortcomings. I argue further that, given some minimal plausible assumptions about the evolution of morality made by Sinclair, no assignment of descriptive content is possible. Contrary to prevailing assumptions, the combination of moral adaptationism and teleosemantics suggests that moral judgments lack descriptive content. (shrink)

While broadly in agreement with the conclusion that the exponentially discounted utility model (EDU) is not a universally valid rationality standard, I want to defend some intertemporal rationality criteria related to EDU, which Craig Callender might not share.

In the first place, I show that many of the concerns that he raises are in fact compatible with intertemporal consistency (and sometimes even with EDU). Secondly, I rebut those (...) arguments that directly challenge consistency. I conclude that while we disagree on the rationality of consistency, we can nevertheless agree on its non-universality and its limited justification of policy interventions. (shrink)

As well as disagreeing about how much one should donate to charity, moral theories also disagree about where one should donate. In light of this disagreement, how should the morally uncertain philanthropist allocate her donations? In many cases, one intuitively attractive option is for the philanthropist to split her donations across all of the charities that are recommended by moral views in which she has positive credence, with each charity’s share being proportional to her credence in the moral theories that (...) recommend that particular charity. Despite the fact that something like this approach is already being used by real-world philanthropists to distribute billions of dollars of donations, it is not supported by any of the approaches to moral uncertainty that have been proposed thus-far in the philosophical literature. In this paper, we will develop a bargaining-based approach to moral uncertainty that honors the proportionality intuition in favor of splitting one’s donations. We also show how this bargaining-based approach has several further advantages over the best alternative proposals. (shrink)

Two agents endowed with different categorisations engage in bargaining to reach an understanding and agree on a common categorisation. We model the process as a simple non-cooperative game and demonstrate three results. When the initial disagreement is focused, the bargaining process has a zero-sum structure. When the disagreement is widespread, the zero-sum structure disappears and the unique equilibrium requires a retraction of consensus: two agents who individually associate a region with the same category end up rebranding it under (...) a different category. Finally, we show that this last equilibrium outcome is Pareto dominated by a cooperative solution that avoids retraction; that is, the unique equilibrium agreement may be inefficient. (shrink)

On occasion, in multilateral negotiations, interested parties make unilateral demands. Certain agreements need unanimity. However, a lesser degree of consensus may be feasible. In this paper, an alternating demand bargaining game among n players is proposed, which envisages varying consensus requirements and commitment, both crucial in generating a unique and efficient outcome of the bargaining process.

David Gauthier's Morals by Agreement presents a partial theory of distributive justice. It is partial because it applies only to the distribution of gains from joint endeavors, or what we may call the ‘social surplus’ from cooperation. This surplus is the benefit we receive from cooperation insofar as this is greater than what we might have produced through individual efforts without interaction with others. The central core of Gauthier's theory of distributive justice is his bargaining theory of ‘minimax relative (...) concession’ or MRC. Whether his theory is compelling turns essentially on whether MRC is workable and compelling. It is this issue that I wish to address. (shrink)
