  1. Time discounting, consistency, and special obligations: a defence of Robust Temporalism.Harry R. Lloyd - 2021 - Global Priorities Institute, Working Papers 2021 (11):1-38.
    This paper defends the claim that mere temporal proximity always and without exception strengthens certain moral duties, including the duty to save – call this view Robust Temporalism. Although almost all other moral philosophers dismiss Robust Temporalism out of hand, I argue that it is prima facie intuitively plausible, and that it is analogous to a view about special obligations that many philosophers already accept. I also defend Robust Temporalism against several common objections, and I highlight its relevance to a (...)

  2. ‘Pure’ Time Preferences Are Irrelevant to the Debate over Time Bias: A Plea for Zero Time Discounting as the Normative Standard.Preston Greene - 2021 - Australasian Philosophical Review 5 (3):254-265.
    I find much to like in Craig Callender's [2022] arguments for the rational permissibility of non-exponential time discounting when these arguments are viewed in a conditional form: viz., if one thinks that time discounting is rationally permissible, as the social scientist does, then one should think that non-exponential time discounting is too. However, time neutralists believe that time discounting is rationally impermissible, and thus they take zero time discounting to (...)

  3. Discounting for public policy: A survey.Hilary Greaves - 2017 - Economics and Philosophy 33 (3):391-439.
    This article is a critical survey of the debate over the value of the social discount rate, with a particular focus on climate change. The ma- jority of the material surveyed is from the economics rather than from the philosophy literature, but the emphasis of the survey itself is on founda- tions in ethical and other normative theory rather than highly technical details. I begin by locating the standard approach to discounting within the overall landscape of ethical theory, and (...)

  4. Rationality and Future Discounting.Arif Ahmed - 2018 - Topoi 39 (2):245-256.
    The best justification of time-discounting is roughly that it is rational to care less about your more distant future because there is less of you around to have it. I argue that the standard version of this argument, which treats both psychological continuity and psychological connectedness as reasons to care about your future, can only rationalize an irrational—because exploitable—form of future discounting.

    Temporal Discounting and Climate Change.J. Paul Kelleher - forthcoming - In Nina Emery (ed.), The Routledge Companion to Philosophy of Time. Routledge.
    Temporal discounting is a technical operation in climate change economics. When discount rates are positive, economic evaluation treats future benefits as less important than equivalent present benefits. This chapter explains and critically evaluates four different reasons economists have given for tying discount rates to the interest rates we observe in real-world markets. I suggest that while philosophers have correctly criticized three of these reasons, their criticisms of the fourth miss the mark. This is because philosophers have not taken heed (...)

  6. Discounting future health.Hilary Greaves - forthcoming - In Norheim Emanuel Jamison Johansson Millum Otterson Ruger and Verguet (ed.), Global health priority-setting: Cost-effectiveness and beyond. Oxford University Press.
    In carrying out cost-benefit or cost-effective analysis, a discount rate should be applied to some kinds of future benefits and costs. It is controversial, though, whether future health is in this class. I argue that one of the standard arguments for discounting (from diminishing marginal returns) is inapplicable to the case of health, while another (favouring a pure rate of time preference) is unsound in any case. However, there are two other reasons that might support a positive discount (...)

  7. Arbitrariness Arguments against Temporal Discounting.Tim Smartt - 2021 - Australasian Philosophical Review 5 (3):302-308.
    Craig Callender [2022] provides a novel challenge to the non-arbitrariness principle. His challenge plays an important role in his argument for the rational permissibility of a non-exponential temporal discounting rate. But the challenge is also of wider interest: it raises significant questions about whether we ought to accept the non-arbitrariness principle as a constraint on rational preferences. In this paper, I present two reasons to resist Callender’s challenge. First, I present a reason to reject his claim that the non-arbitrariness (...)

  8. How Much Do We Discount Past Pleasures?Preston Greene, Andrew J. Latham, Kristie Miller & James Norton - 2022 - American Philosophical Quarterly 59 (4):367-376.
    Future-biased individuals systematically prefer pleasures to be in the future and pains to be in the past. Empirical research shows that negative future-bias is robust: people prefer more past pain to less future pain. Is positive future-bias robust or fragile? Do people only prefer pleasures to be located in the future, compared to the past, when those pleasures are of equal value, or do they continue to prefer that pleasures be located in the future even when past pleasures outweigh future (...)

  9. The Normative Standard for Future Discounting.Craig Callender - 2021 - Australasian Philosophical Review 5 (3):227-253.
    This paper challenges the conventional wisdom dominating the social sciences and philosophy regarding temporal discounting, the practice of discounting the value of future utility when making decisions. Although there are sharp disagreements about temporal discounting, a kind of standard model has arisen, one that begins with a normative standard about how we should make intertemporal comparisons of utility. This standard demands that in so far as one is rational one discounts utilities at future times with an exponential (...)

  10. Pure time preference in intertemporal welfare economics.J. Paul Kelleher - 2017 - Economics and Philosophy 33 (3):441-473.
    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 (...)

  11. What Time-travel Teaches Us About Future-Bias.Kristie Miller - 2021 - Philosophies 6 (38):38.
    Future-biased individuals systematically prefer positively valenced events to be in the future (positive future-bias) and negatively valenced events to be in the past (negative future-bias). The most extreme form of future-bias is absolute future-bias, whereby we completely discount the value of past events when forming our preferences. Various authors have thought that we are absolutely future-biased (Sullivan (2018:58); Parfit (1984:173) and that future-bias (absolute or otherwise) is at least rationally permissible (Prior (1959), Hare (2007; 2008), Kauppinen (2018), Heathwood (2008)).

  13. The outlier paradox: The role of iterative ensemble coding in discounting outliers.Michael Epstein, Jake Quilty-Dunn, Eric Mandelbaum & Tatiana Emmanouil - forthcoming - Journal of Experimental Psychology: Human Perception and Performance 1.
    Ensemble perception—the encoding of objects by their group properties—is known to be resistant to outlier noise. However, this resistance is somewhat paradoxical: how can the visual system determine which stimuli are outliers without already having derived statistical properties of the ensemble? A simple solution would be that ensemble perception is not a simple, one-step process; instead, outliers are detected through iterative computations that identify items with high deviance from the mean and reduce their weight in the representation over time.

    We propose a theoretical model to explain the usage of time-inconsistent behavior as a strategy to exploit others when reputation and trust have secondary effects on the economic outcome. We consider two agents with time-consistent preferences exploiting common resources. Supposing that an agent is believed to have time-inconsistent preferences with probability p, we analyze whether she uses this misinformation when she has the opportunity to use it. Using the model originally provided by Levhari and Mirman (Bell J (...)

    To obtain effective fusion results of multi source evidences with different importance, an evidence fusion method with importance discounting factors based on neutrosopic probability analysis in DSmT framework is proposed. First, the reasonable evidence sources are selected out based on the statistical analysis of the pignistic probability functions of single focal elements. Secondly, the neutrosophic probability analysis is conducted based on the similarities of the pignistic probability functions from the prior evidence knowledge of the reasonable evidence sources. Thirdly, the (...)

    This paper investigates two assumptions of the exponential discounted utility theory (EDU) to which Callender draws our attention: namely that we can cleanly distinguish pure from impure temporal preferences, and that past discounting can be ignored. Drawing on recent empirical work in this area, we argue that in so far as one might have thought that past-directed preferences are more pure than future ones, then there is evidence that people’s pure preferences (in so far as we can make sense (...)

    About 80 % of all convicted have had a prior record of conviction.

    Economic models describe individuals in terms of underlying characteristics, such as taste for some good, sympathy level for another player, time discount rate, risk attitude, and so on. In real life, such characteristics change through experiences: taste for Mozart changes through listening to it, sympathy for another player through observing his moves, and so on. Models typically ignore change, not just for simplicity but also because it is unclear how to incorporate change. I introduce a general axiomatic framework for (...)

    Intertemporal choice is the study of how people make choices about what and how much to do at various points in time, when choices at one time influence the possibilities available at other points in time. These choices are influenced by the relative value people assign to two or more payoffs at different points in time. Most choices require decision-makers to trade off costs and benefits at different points in time. These decisions may be about (...)

I show that libertarian paternalism is grounded on a peculiar model of personal identity, and that the argument according to which nudges may improve one’s self-assessed well-being can be seriously questioned. I show that time inconsistencies do not necessarily reveal that the decision maker is irrational: they can also be the result of discounting over the degree of psychological connectedness between our successive selves rather than over (...)

I show that these calculation methods are not equivalent and discuss some of the formal difficulties each method faces. I show that if we don’t discount the value of future health, there is a sense in which the choice of calculation method is a mere (...)

    We introduce a ranking of multidimensional alternatives, including uncertain prospects as a particular case, when these objects can be given a matrix form. This ranking is separable in terms of rows and columns, and continuous and monotonic in the basic quantities. Owing to the theory of additive separability developed here, we derive very precise numerical representations over a large class of domains (i.e., typically notof the Cartesian product form). We apply these representationsto (1)streams of commodity baskets through time, (2)uncertain (...)

  25. Why future-bias isn't rationally evaluable.Callie K. Phillips - 2021 - Res Philosophica 98 (4):573-596.
    Future-bias is preferring some lesser future good to a greater past good because it is in the future, or preferring some greater past pain to some lesser future pain because it is in the past. Most of us think that this bias is rational. I argue that no agents have future-biased preferences that are rationally evaluable—that is, evaluable as rational or irrational. Given certain plausible assumptions about rational evaluability, either we must find a new conception of future-bias that avoids the (...)

    The concept of work–family balance was introduced in the 1970s in the United Kingdom based on a work–leisure dichotomy, which was invented in the mid-1800s. It is usually related to the act of balancing of inter-role pressures between the work and family domains that leads to role conflict. The conflict is driven by the organizations’ views of the “ideal worker” as well as gender disparities and stereotypes that ignore or discount the time spent in the unpaid work of family (...)

  36. Discounting Desirable Gambles.Gregory Wheeler - 2021 - Proceedings of Machine Learning Research 147:331-341.
    The desirable gambles framework offers the most comprehensive foundations for the theory of lower pre- visions, which in turn affords the most general ac- count of imprecise probabilities. Nevertheless, for all its generality, the theory of lower previsions rests on the notion of linear utility. This commitment to linearity is clearest in the coherence axioms for sets of desirable gambles. This paper considers two routes to relaxing this commitment. The first preserves the additive structure of the desirable gambles framework and (...)

    Utility discounting in intertemporal economic modelling has been viewed as problematic, both for descriptive and normative reasons. However, positive utility discount rates can be defended normatively; in particular, it is rational for future utility to be discounted to take into account model-independent outcomes when decision-making under risk. The resultant values will tend to be smaller than descriptive rates under most probability assignments. This also allows us to address some objections that intertemporal considerations will be overdemanding. A principle for utility (...)

    Many population axiologies avoid the Repugnant Conclusion by endorsing Superiority: some number of great lives is better than any number of mediocre lives. But as Nebel shows, RC follows from the Intrapersonal Repugnant Conclusion: a guaranteed mediocre life is better than a sufficiently small probability of a great life. This result is concerning because IRC is plausible. Recently, Kosonen has argued that IRC can be true while RC is false if small probabilities are discounted to zero. This article details the (...)

  41. Descriptive versus Prescriptive Discounting in Climate Change Policy Analysis.Kelleher J. Paul - 2017 - Georgetown Journal of Law and Public Policy 15:957-977.
    This paper distinguishes between five different approaches to social discount rates in climate change economics, criticizes two of these, and explains how the other three are to some degree mutually compatible. It aims to shed some new light on a longstanding debate in climate change economics between so-called “descriptivists” and “prescriptivists” about social discounting. The ultimate goal is to offer a sketch of the conceptual landscape that makes visible some important facets of the debate that very often go unacknowledged.

  43. Additively-separable and rank-discounted variable-population social welfare functions: A characterization.Dean Spears & H. Orri Stefansson - 2021 - Economic Letters 203:1-3.
    Economic policy evaluations require social welfare functions for variable-size populations. Two important candidates are critical-level generalized utilitarianism (CLGU) and rank-discounted critical-level generalized utilitarianism, which was recently characterized by Asheim and Zuber (2014) (AZ). AZ introduce a novel axiom, existence of egalitarian equivalence (EEE). First, we show that, under some uncontroversial criteria for a plausible social welfare relation, EEE suffices to rule out the Repugnant Conclusion of population ethics (without AZ’s other novel axioms). Second, we provide a new characterization of CLGU: (...)

    Defining Time.Vincent Vesteby - manuscript
    The knowledge of the evident qualities of time, such as its all-encompassing unidirectional relentless change, does not provide answers as to what time is or why it occurs. Those qualities do not identify what it is in the universe that intrinsically has those qualities. Thus, previously it has not been possible to achieve an adequate definition of time that includes the answers to those questions. Now, with the discovery that the continuing-existence of space plays the role of (...)

    Regard time machines.Davide Peressoni - unknown
    Theorem (Will time machines be build?). The probability that in future a time machine that can travel to the past would be build is very low.

  46. Reversing the arrow of time.Bryan W. Roberts - 2022 - Cambridge: Cambridge University Press.
    'The arrow of time' refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories, which has wide-ranging implications for both physics and its philosophy. This link helps to clarify how we can learn about the symmetries of our world, how to understand the relationship between symmetries and what is real, (...)

    From Time to Time.Nathan Salmon - 2017 - In Shyam Wuppuluri & Giancarlo Ghirardi (eds.), Space, Time and Limits of Human Understanding. Cham: Springer. pp. 61-75.
    The topic is time travel of the sort depicted in H. G. Wells’ classic novel, The Time Machine—Wellsian time travel. The range of proper applicability of the concept of Wellsian time travel is investigated. The results of this investigation are applied to provide a new argument against the metaphysical possibility of time travel in absolute time. Alternatively, the argument is against the possibility of Wellsian time travel relative to a single temporal frame of (...)

  48. A philosopher’s guide to discounting.Kian Mintz-Woo - 2021 - In Mark Bryant Budolfson, Tristram McPherson & David Plunkett (eds.), Philosophy and Climate Change. Oxford University Press. pp. 90-110.
    This chapter introduces several distinctions relevant to what is called the “discounting problem”, since the issue is how (future) costs and benefits are discounted to make them comparable in present terms. The author defends the claim that there are good reasons to adopt Ramsey-style discounting in the context of climate change: the Ramsey rule is robust, flexible, and well-understood. An important distinction involved in discounting—“descriptivism” and “prescriptivism”—is discussed. It is argued that, even if we adopt prescriptivism, and (...)

  49. Risky Problems: Discounting Future Lives.Zimu Zhang - manuscript
    In "A Mathematical Theory of Saving", Ramsey writes, “it is assumed that we do not discount later enjoyments in comparison with earlier ones, a practice which is ethically indefensible and arises merely from the weakness of imagination” (Ramsey 543). Ramsey doesn’t tell us how discounting the enjoyment of future lives is ethically indefensible. Discounting is, however, very prevalent in the common economist’s work. Thus, Ramsey’s claim might be surprising. In this paper, then, I do two things. Firstly, I (...)

  50. A new defence of probability discounting.Kian Mintz-Woo - 2017 - In Adrian Walsh, Säde Hormio & Duncan Purves (eds.), The Ethical Underpinnings of Climate Economics. Oxford: Routledge. pp. 87-102.
    When probability discounting (or probability weighting), one multiplies the value of an outcome by one's subjective probability that the outcome will obtain in decision-making. The broader import of defending probability discounting is to help justify cost-benefit analyses in contexts such as climate change. This chapter defends probability discounting under risk both negatively, from arguments by Simon Caney (2008, 2009), and with a new positive argument. First, in responding to Caney, I argue that small costs and benefits need (...)
