The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

This article argues for a novel approach to the measurement of freedom of choice, on which the availability of an option is a matter of degree, rather than a bivalent matter of being either available or not. This approach is motivated by case studies involving weakness of will, where deficiencies in willpower seem to impair individual freedom by making certain alternatives much harder to pursue. This approach is perfectly general, however: its graded analysis of option availability can be extended to (...) cases where weakness of will is not involved and can be used to generalize numerous existing measures of freedom.

If preference-based freedom rankings are based on all-things-considered preferences, they risk judging phenomena of adaptive preferences as freedom enhancing. As a remedy, it has been suggested to base preference-based freedom rankings on reasonable preferences. But this approach is also problematic. This article argues that the quest for a remedy is unnecessary. All-things-considered preferences retain information on whether the availability of an option contributes to the value that freedom has for a person’s self-expression. If preference-based freedom rankings use all-things-considered preferences to (...) evaluate whether an option contributes to a person’s self-expression, they are immune to the problem posed by adaptive preferences.

Ranking finite subsets of a given set X of elements is the formal object of analysis in this article. This problem has found a wide range of economic interpretations in the literature. The focus of the article is on the family of rankings that are additively representable. Existing characterizations are too complex and hard to grasp in decisional contexts. Furthermore, Fishburn (1996), Journal of Mathematical Psychology 40, 64–77 showed that the number of sufficient and necessary conditions that are needed to (...) characterize such a family has no upper bound as the cardinality of X increases. In turn, this article proposes a way to overcome these difficulties and allows for the characterization of a meaningful (sub)family of additively representable rankings of sets by means of a few simple axioms. Pattanaik and Xu’s (1990), Recherches Economiques de Louvain 56, 383–390) characterization of the cardinality-based rule will be derived from our main result, and other new rules that stem from our general proposal are discussed and characterized in even simpler terms. In particular, we analyze restricted-cardinality based rules, where the set of “focal” elements is not given ex-ante; but brought out by the axioms. (shrink)

Freedom is one of the most important moral and political ideals. Questions concerning degrees of overall freedom are therefore of the utmost moral and political concern. To answer these questions we need to know how to measure degrees of overall freedom. This paper offers a novel defence of the partly evaluative approach to freedom measurement against a recent critique of it. According to the partly evaluative approach, the question of how free one is depends partly on the specific value of (...) the freedoms one possesses and partly on their physical extension. According to the critique, because of its reference to freedoms’ specific value, the partly evaluative approach fails to capture freedoms’ non-specific value, which is what it should capture. In this paper I argue that this critique is unfounded, by showing that even measures of more mundane things, which nevertheless, like freedom, present us with a commensuration problem, sometimes involve evaluative considerations similar to the ones that the partly evaluative approach invokes.

When assessing institutions and social outcomes, it matters how free society is within them (‘societal freedom’). For example, does capitalism come with greater societal freedom than socialism? For such judgements, freedom theorists typically assume Individualism: societal freedom is simply the aggregate of individual freedom. However, G.A. Cohen’s well-known case provides a challenge: imagine ten prisoners are individually free to leave their prison but doing so would incarcerate the remaining nine. Assume further that no one actually leaves. If we adopt Individualism (...) plus the standard liberal view of freedom, such incarceration seems to leave societal freedom unaffected. This is an important theoretical challenge: it seems we must either reject Individualism or reject, or at least amend, the liberal view. Cohen also suggests his case, and the collective unfreedom therein, helps us capture how proletarians are unfree under capitalism. In this article, I argue that we can solve Cohen’s puzzle, if we focus on how power can reduce freedom. If we adopt the republican view of freedom, we can say that prisoners are unfree in Cohen’s case because they are dominated by the other prisoners. This solution keeps Individualism but moves beyond liberal freedom. I then also show how this individualistic framework captures proletarian unfreedom. (shrink)

There exists psychological evidence that consumers do not consider all available items in the market, which can lead to the “more-is-less” effect, a phenomenon where having more options causes a welfare reduction (Llears et al. in J Econ Theory 170:70–85, 2017). Under this more-is-less effect, we face a dilemma that adding new opportunities may both improve and worsen individual well-being. This study proposes a hypothesis that “more is always better,” which implies that adding new opportunities cannot worsen individual well-being, is (...) a bias to which moral heuristics leads. A satisfactory resolution of this dilemma is act-consequentialism over menus, which is an ex-post and third-party evaluation of opportunity sets. We provide an axiomatic foundation for act-consequentialism over menus and apply it to policymakers’ menu-providing policies. (shrink)

Republican freedom is freedom from domination juxtaposed to negative freedom as freedom from interference. Proponents argue that republican freedom is superior since it highlights that individuals lose freedoms even when they are not subject to interference, and claim republican freedom is more ‘resilient’. Republican freedom is trivalent, that is, it includes the idea that someone might be non-free to perform some actions rather than unfree, and in that sense everyone regards republican freedom as different from negative freedom. Trivalence makes republican (...) freedom moralized according to negative libertarians. Beyond that, negative libertarians argue that all the supposed advantages of republican freedom are compatible with those of pure negative-freedom measures. That is, losses and gains of republican freedom are captured in measures of pure negative freedom, and any protection for republican freedom also protects negative freedom, ensuring each is equally resilient. Since republican freedom has no advantages over negative freedom, but has other problems (is moralized and is trivalent), negative freedom is superior. I examine this debate in this article through the ‘coalition problem’ for republican freedom. The coalition problem is that since there is always a coalition of others who could dominate any agent in any sphere, all agents are subject to domination, and hence no one can ever have republican freedom. Pettit’s simple solution to this reductio ad absurdum distinguishes potential from actual coalitions. Individuals are only dominated by actual coalitions, and not by potential ones. The simple solution highlights moralization problems as it demonstrates that domination cannot be purely institutionally defined, but requires consideration of dispositions and expectations about others’ behaviour. I argue that the differences between the ‘free man’ and ‘unfree person’ paradigmatic to republican arguments is best captured not by the difference between domination and interference, but, rather, from familiar distinctions between different types of rights and freedoms. Resilience is a practical matter that might track some of these familiar distinctions. (shrink)

Freedom is among the central values in political philosophy. Freedom also features heavily in normative arguments in ethics, politics, and law. Yet different sides often invoke freedom to establish very different conclusions. Some argue that freedom imposes strict constraints on state power. For example, when promoting public health, there is a limit on how far the state can interfere with individual freedom. Others, in contrast, argue that freedom is not just a constraint but also an important goal of state power (...) and collective action. Good public health policy, for example, promotes people’s freedom. Of course, different arguments often draw on different theories of freedom. So, to evaluate such arguments, we need to analyze these different theories and their implications and assess their plausibility. -/- The broadly liberal tradition views freedom as being about external options. Such theories typically start with an account of when someone has a specific freedom or unfreedom to do something. For example, some argue that only a narrow set of interpersonal interferences count as constraints on freedom. Others argue that a far broader set of factors, including ill health and natural constraints, can reduce one’s freedom. -/- Since the 1980s and 1990s, scholarship has increasingly recognized that to use liberal freedom in normative arguments, one must move beyond specific freedom and unfreedom. Most laws and policies both subtract and add specific freedoms. What matters is how a person’s freedom is affected overall. Philosophers and economists have thus engaged in intricate debates about how to measure overall freedom. Moreover, policies and law affect not only one person at one point in time but also multiple persons across time. So, liberal freedom-based arguments also require distributive criteria for intertemporal and interpersonal distributions of freedom. -/- In the early 21st century, republicanism has developed into a prominent alternative to liberal theories. Republicans argue that being a free person is not just, or not even primarily, about liberal option-freedom. Freedom requires being free from dominating power. Republicans and liberals have engaged in a lively debate on who offers the better theory. In developing the republican ideal, republicans also engage in intramural debates. For example, is domination primarily an interpersonal or structural phenomenon? And what economic institutions does republicanism imply? -/- Theorizing around freedom has become richer and moved from narrower questions regarding specific freedom and unfreedom to overall freedom and to republican theories of nondomination. But recent theorizing also seeks to extend its focus and scope. Historically, theorizing started with the freedom of able-bodied male citizens within nation states. Recent theorizing shifts the focus to include issues around gender, disability, freedom at the international level, and the freedom of nonhuman animals and future generations. Beyond fascinating implications of existing theories, a more inclusive focus is likely to also yield important lessons on how current theories can be improved. (shrink)
