According to G. E. Moore, moral expertise requires abilities of several kinds: the ability to factor judgments of right and wrong into (a) judgments of good and bad and (b) judgments of cause and effect, (2) the ability to use intuition to make the requisite judgments of good and bad, and (3) the ability to use empirical investigation to make the requisite judgments of cause and effect. Moore’s conception of moral expertise is thus extremely demanding, but he supplements it with (...) some very simple practical guidance. (shrink)

Standard theories of rational decision making and rational preference embrace the idea that there is something special about the present. Standard decision theory, for example, demands that agents privilege the perspective of the present (i.e., the time of decision) in evaluating what to do. When forming preferences, most philosophers believe that a similar focus on the present is justified, at least in the sense that rationality requires or permits future experiences to be given more weight than past ones. In this (...) dissertation, I examine such theories in light of the expected success of the agents who follow them. In Chapters 2 and 3, I show that this bias toward the present is a liability: it tends to make agents less successful than they might otherwise be. I also show how these problems can be avoided: In the case of rational decision making, we must privilege the beginning rather than the present (what I call “inceptive maximization”). In the case of rational preferences, we must be completely temporally neutral. -/- In chapters 4 and 5 I introduce a larger framework in which to interpret these results. My core thesis is that practical rationality is a form of conditional reliability. Practically rational decisions, preferences, intentions, or other relevant factors reliably produce whatever we take to be of value, conditional on an agent’s beliefs. This focus on value-conduciveness is thus the analog of the focus on truth-conduciveness in reliability theories of epistemic norms. Like reliabilism in epistemology, I show that practical reliabilism is supported by a methodologically naturalistic approach to normativity. In this way and others, I argue that epistemic and practical reliabilism interconnect to create an overarching theory of normativity. (shrink)

In this article, a new, idealizing-hermeneutic methodological approach to developing a theory of philosophical arguments is presented and carried out. The basis for this is a theory of ideal philosophical theory types developed from the analysis of historical examples. According to this theory, the following ideal types of theory exist in philosophy: 1. descriptive-nomological, 2. idealizing-hermeneutic, 3. technical-constructive, 4. ontic-practical. These types of theories are characterized in particular by what their basic types of theses are. The main task of this (...) article is then to determine the types of arguments that are suitable for justifying these types of theses. Surprisingly, practical arguments play a key role here.

In this thesis, I discuss the aggregation problem for T. M. Scanlon’s “contractualism”. I argue that Scanlonian contractualists have the following two options when it comes to the aggregation problem. First, they can choose to limit aggregation directly via a specific version of the Relevance View, “Sequential Claims-Matching”. Second, Scanlonian contractualists can adopt a so-called “mixed solution” of which I propose a specific version. My mixed solution does not limit aggregation. Rather, it either avoids some of the counterintuitive results in (...) certain cases, or at least makes these same results look a lot less counterintuitive by putting them into perspective thanks to a plausible plurality of precisely specified values. The stakes between these two options are as follows. The first option justifies Scanlon’s intuition in one vs. many cases of which his “World Cup Case” is one example, but it comes at the cost of a seemingly quite limited range of application: any version of the Relevance View only works in cases in which we have no more than two groups of competing claimants. The second option has the exact opposite implications: my mixed solution cannot justify Scanlon’s intuition in one vs. many cases, but it could be applied to any case with any number of groups of competing claimants. In this choice between pre-theoretical intuition and feasibility, I would urge Scanlonian contractualists to choose feasibility. (shrink)

This chapter first introduces naturalistic approaches to ethics more generally and distinguishes methodological ethical naturalism (the focus of this chapter), from metaphysical ethical naturalism. The second part then discusses evolutionary ethics as a specific variant of methodological ethical naturalism. After introducing the concepts of evolutionary theory that are relevant for evolutionary ethics, I will sketch the history of evolutionary ethics, which offers an interesting lesson about why it became a controversial topic, and then focus on four central questions about ethics (...) that can be approached from within the framework of evolutionary ethics: 1. What should we do? 2. Why are we moral? 3. Are there moral facts? 4. Can we have justified moral beliefs and moral knowledge? (shrink)

This introduction aims to describe some fundamental problems of intergenerational justice and climate change. It also intends to provide comments on improved versions of some of the best papers presented in the International Meeting “Intergenerational Justice and Climate Change: juridical, moral and political issues” that took place at Cordoba National University (Argentina), in September 2017. In that meeting, the discussion focused on these topics by considering the ideas of the two keynote speakers invited to the event: Lukas H. Meyer and (...) Alessandro Pinzani. I devote the last part of this essay to discuss two pressing issues concerning climate change whose practical solutions challenge our standard understanding of the notion of harm. I discuss, on the one hand, certain issues related with the non-identity problem. On the other hand, I try to identify what kind of obligation do we have when we talk about minimizing the number of people who will suffer harm as a result of the adverse effects of climate change.

This thesis offers a teleosemantic account of moral discourse and judgment. It develops a number of views about the function and content of moral judgments and the nature of moral discourse based on Ruth Millikan’s theory of intentional content and the functions of intentional attitudes. Non-cognitivists in meta-ethics have argued that moral judgments are more akin to desires and other motivational attitudes than to descriptive beliefs. I argue that teleosemantics allows us to assign descriptive content to motivational attitudes and hence (...) that even if the non-cognitivist is correct, moral judgments can be said to describe the world. Moreover, given further teleosemantic assumptions, this conclusion has consequences that are both surprising and interesting. First of all, while moral judgments have descriptive content, moral statements do not. The purpose of moral discourse is not to convey beliefs that are true simpliciter, but to convey attitudes that are descriptively correct when tokened by the addressee. Consequently, moral discourse requires speakers to adapt to hearers in order to secure their assent and bring them into "community of judgment" with themselves. Secondly, the descriptive content of a motivational attitude is partly a matter of the subject’s own preferences and circumstances. In particular, the descriptive correctness of a moral judgment is partly a function of the degree to which it is shared with others. Since a moral judgment also motivates the subject to spread it, it has the ability to, in a certain sense, make itself true. If regular descriptive beliefs are supposed to adapt the subject to the world, a moral judgment also has the capacity to adapt the world to the subject. (shrink)

Social contract thought has always contained multiple and mutually conflicting lines of argument; the minimalist contractarianism so influential today represents the weaker of two main constellations of claims. I make the case for a Kantian contract theory that emphasizes the bedrock principle of consent of the governed instead of the mere heuristic device of the exit from the state of nature. Such a shift in emphasis resolves two classic difficulties: tradi- tional contract theory’s ahistorical presumption of a pre-political settlement, and (...) its impossibly high demands on citizens seeking to practice self-rule. Kant’s solutions to these problems of property rights and citizenship are found in his political works, rather than the ethical works through which Kant’s political theory is usually interpreted.

The paper focuses on Anthony de Jasay's "anarcho-liberalism" as based oon his game-theoretic approach to the problem of public goods provision.

One of the distinctive features of Gerald Gaus’s public justification theory is his extensive use of the empirical data from the social sciences to support his normative claims. One such claim which stands out for its importance, within the context of Gaus’s theory, is the evolution of strong reciprocity: over time, members of large societies develop a tendency to follow social rules and punish defectors. This claim, in turn, is supported by several studies in experimental economics involving mixed motive games, (...) which show how subjects are inclined to punish, even at a net cost for themselves, any perceived violation of social norms such as fairness. While critics of Gaus’s theory focused mainly on whether the use of empirical evidence in a normative theory is prima facie admissible, in this paper I address two different issues. The first concerns the accuracy of the empirical evidence used by Gaus’s theory, and whether the conclusions advanced by the social scientists on the grounds of this evidence are actually sound. The second issue, on the other hand, concerns the consistency between the empirical assumptions underlying these experiments and the claims of Gaus’s theory. I argue that both concerns are warranted. On the one hand, there is empirical evidence that the rule-following behavior observed in experiments involving mixed motive games is context dependent: the tendency of subjects to follow rules and punish defectors is strongly correlated to the epistemic constraints, such as anonymity, commonly imposed during the experiments. On the other hand, these constraints hardly reflect the circumstances of life in modern societies, which is the context assumed by Gaus’s justificatory theory. I conclude that Gaus’s account of rule-following punishers is not altogether invalidated, but the empirical evidence from experimental economics is insufficient to support it. (shrink)

In a recent discussion of disenchantment and re-enchantment Charles Taylor suggests that it is possible to respond to the disenchanted view of the world, in which meaning and value are understood as subjective projections, by articulating a re-enchanted sense of nature or the universe from the perspective of human ‘agency-in-the-world’, in which meaning and value are objective. The question I address in this thesis is, what could it mean to articulate a re-enchantment from within our ‘agency-in-the-world’? In Chapter One I (...) examine the work of John McDowell in order to explore the possibility that he gives sense to the idea of a re-enchantment from within our agency-in-the-world. I conclude that he provides one way of doing so. However I argue that McDowell’s naturalism of second nature can seem limited as it does not address the ‘proto-religious’ dimension to Taylor’s understanding of re-enchantment. In Chapter Two I turn to the work of Roger Scruton to consider whether he provides a re-enchantment from within our agency-in-the-world that does accommodate this proto-religious dimension. I conclude that he does, but raise concerns about how convincing Scruton’s re-enchantment is. I argue that, from a McDowellian point of view, a case can be made that Scruton implicitly accepts as true certain significant elements of the disenchanted view of the world. In Chapter Three I look to the later Heidegger for an alternative re-enchantment from within our agency-in-the-world that attempts to accommodate the proto-religious. I focus on two interpretations of the later Heidegger given by Julian Young and Charles Taylor. In response to a worry put forward by Young, I argue that Charles Taylor’s interpretation can accommodate a proto-religious dimension. In my Conclusion I argue that McDowell’s naturalism of second nature and the understanding of our agency-in-the-world as presented by Taylor’s Heidegger, form interestingly continuous re-enchantments. On this basis I argue that although McDowell himself does not extend his idea of second nature to accommodate the proto-religious, the example of later Heidegger shows that there is nothing inherently limited about the framework of second nature that means it cannot be extended to encompass important proto-religious responses to the world.

How should an agent decide what to do when she is uncertain not just about morally relevant empirical matters, like the consequences of some course of action, but about the basic principles of morality itself? This question has only recently been taken up in a systematic way by philosophers. Advocates of moral hedging claim that an agent should weigh the reasons put forward by each moral theory in which she has positive credence, considering both the likelihood that that theory is (...) true and the strength of the reasons it posits. The view that it is sometimes rational to hedge for one's moral uncertainties, however, has recently come under attack both from those who believe that an agent should always be guided by the dictates of the single moral theory she deems most probable and from those who believe that an agent's moral beliefs are simply irrelevant to what she ought to do. Among the many objections to hedging that have been pressed in the recent literature is the worry that there is no non-arbitrary way of making the intertheoretic comparisons of moral value necessary to aggregate the value assignments of rival moral theories into a single ranking of an agent's options. -/- This dissertation has two principal objectives: First, I argue that, contra these recent objections, an agent's moral beliefs and uncertainties are relevant to what she rationally ought to do, and more particularly, that agents are at least sometimes rationally required to hedge for their moral uncertainties. My principal argument for these claims appeals to the enkratic conception of rationality, according to which the requirements of practical rationality derive from an agent's beliefs about the objective, desire-independent value or choiceworthiness of her options. Second, I outline a new general theory of rational choice under moral uncertainty. Central to this theory is the idea of content-based aggregation, that the principles according to which an agent should compare and aggregate rival moral theories are grounded in the content of those theories themselves, including not only their value assignments but also the metaethical and other non-surface-level propositions that underlie, justify, or explain those value assignments.

I argue, contrary to the consensus of most contemporary work in ethics, that there are no (fundamentally, distinctively) prudential reasons for action. That is to say: there is no class of reasons for action that is distinctively and fundamentally about the promotion of the agent’s own well-being. Considerations to do with the agent’s well-being can supply the agent with reasons only in virtue of her well-being mattering morally or in virtue of her caring about her own well-being. In both of (...) these cases, the way that such prudential considerations supply reasons for action is a way that the well-being of others can supply reasons for action too. (shrink)

Authority figures permeate our daily lives, particularly, our political lives. What makes authority legitimate? The current debates about the legitimacy of authority are characterised by two opposing strategies. The first establish the legitimacy of authority on the basis of the content of the authority’s command. That is, if the content of the commands meet some independent normative standard then they are legitimate. However, there have been many recent criticisms of this strategy which focus on a particular shortcoming – namely, its (...) seeming inability to account for who can legitimately command whom. This is the basis of the second strategy, which attempts to characterize the normative relationship that underlies and makes possible authoritative commands. The central point of Part I is that these two strategies are, in fact, not opposed and both raise questions which a theory of legitimacy must answer. If this is the case, then we need to ask: how ought we to determine the legitimacy both of the content of commands as well as who can command whom? Part II will answer this question. Starting with the question of standing, I argue that we ought not to look for normative principles outside of the institutions in which authority is embedded. Rather, one ought to start by elaborating the ontology of institutions in which a sui generis form of normativity arises. A joint commitment account of social ontology provides the tools necessary to see how the direction obligations emerge concurrently with the formation of institutions. Similarly, the question of content can be answered by paying close attention to the social ontology of institutions. We need not look beyond the internal constitutive standards of the institution itself. The constitutive standards provide an internal criterion by which the legitimacy of commands can be established.

El artículo defiende que los compromisos son tanto un tipo de acuerdo como un tipo de decisión. Los principales objetivos son: 1) identificar la estructura formal de las situaciones de compromiso en las que alguna decisión de compromiso es inevitable, incluyendo CDs que ponen en riesgo la integridad del decisor; 2) mediante las nociones de juicio básico y compulsivo propuestas por Amartya Sen, establecer cuándo una CD en una situación de compromiso podría estar moralmente justificada. Se concluye que las CDs (...) justificadas implican una contrición moral que ayuda a salvar la distancia entre deontología y consecuencialismo. (shrink)

The following thesis starts from the question «why be moral?» and adresses an action-theoretic strategy for answering this question in the positive by reference to the constitutive natur of actions. In these debates, the epistemology of action has turned into a central issue. The thesis adresses these debates and develops a novel account of the epistemology: an account that may well turn out to provide a ground for the aforementioned constitutivist strategies.

This essay is part of an attempt to reconcile two extreme views in economics: the (neglected) subjective, apriorist approach and the (standard) objective, scientific (i.e., falsifiable) approach. The Austrian subjective view of value, building on Carl Menger’s theory of value, was developed into a theory of economics as being entirely an a priori theory of action. This probably finds its most extreme statement in Ludwig von Mises’ Human Action (1949). In contrast, the standard economic view has developed into making falsifiable (...) predictions about economic phenomena whereby the truth of the assumptions, especially about economic agents, is relatively unimportant: predictive fecundity is all. This finds an extreme statement in Milton Friedman’s introductory essay in his Essays in Positive Economics (1953). However, many economists fall somewhere between the two extremes, such as McKenzie and Tullock (1978). (shrink)

Institutions have often been characterized as responses to conflict, and assumptions about the nature of conflict have frequently determined the structure and scope of political activity. Two prevalent interpretations of conflict portray it as either a conflict of interest or a competition for resources. Yet there is another view of conflict that regards it in terms of a contest of values, something that raises a different set of questions and issues. These issues involve concerns about the incommensurability and incompatibility of (...) values, and challenge contemporary arguments that rely upon the ordering of preferences or that urge the pursuit of a normative consensus. As I argue, both preference based theories and theories of deliberative democracy prove to deal inadequately with the challenges of moral pluralism and value conflict. (shrink)

What is it exactly that we are attributing to a thing when we judge it to be good? According to the orthodox answer, at least in some cases when we judge that something is good we are attributing to it a monadic property. That is, good things are “just plain good.” I reject the orthodox view. In arguing against it, I begin with the idea that a plausible account of goodness must take seriously the intuitive claim that there is something (...) in common between moral and non-moral goodness—something in virtue of which it makes sense to call ‘good’ both the things that are morally good and the things that are non-morally good. However, it is implausible that all judgments about the goodness of things attribute a monadic property to those things, as this does not capture what we mean when we judge something to be non-morally good. Instead, I propose and defend my own relational theory of goodness according to which goodness is a relation that holds between things and ends (or goals). That is, goodness is a relational property such that to be good is to be related in the relevant way to some goal or another. This is true in both the mundane everyday cases and in loftier cases concerned with moral goodness. (shrink)

One of the conceptual limitations of the orthodox game theory is its inability to offer definitive theoretical predictions concerning the outcomes of noncooperative games with multiple rationalizable outcomes. This prompted the emergence of goal-directed theories of reasoning – the team reasoning theory and the theory of hypothetical bargaining. Both theories suggest that people resolve non-cooperative games by using a reasoning algorithm which allows them to identify mutually advantageous solutions of non-cooperative games. The primary aim of this thesis is to enrich (...) the current debate on goaldirected reasoning theories by studying the extent to which the principles of the bargaining theory can be used to formally characterize the concept of mutual advantage in a way which is compatible with some of the conceptually compelling principles of orthodox game theory, such as individual rationality, incentive compatibility, and non-comparability of decision-makers’ personal payoffs. I discuss two formal characterizations of the concept of mutual advantage derived from the aforementioned goal-directed reasoning theories: A measure of mutual advantage developed in collaboration with Jurgis Karpus, which is broadly in line with the notion of mutual advantage suggested by Sugden, and the benefit-equilibrating bargaining solution function, which is broadly in line with the principles underlying Conley and Wilkie’s solution for Pareto optimal point selection problems with finite choice sets. I discuss the formal properties of each solution, as well as its theoretical predictions in a number of games. I also explore each solution concept’s compatibility with orthodox game theory. I also discuss the limitations of the aforementioned goal-directed reasoning theories. I argue that each theory offers a compelling explanation of how a certain type of decision-maker identifies the mutually advantageous solutions of non-cooperative games, but neither of them offers a definitive answer to the question of how people coordinate their actions in non-cooperative social interactions.

This paper contributes to the explanation of human cooperative behaviour, examining the implications of Brian Skyrms’ modelling of the prisoner’s dilemma (PD). Augmenting a PD with signalling strategies promotes cooperation, but a challenge that must be addressed is what prevents signals being subverted by deceptive behaviour. Empirical results suggest that emotional displays can play a signalling role and, to some extent, are secure from subversion. I examine proximate explanations and then offer an evolutionary explanation for the translucency of emotional displays. (...) Selection acts on the basis of lifetime fitness consequences and, crucially for my argument, the intensity of selection decreases over the course of a lifetime. Hence we tend to possess traits that promote survival when young and, with regard to emotional displays, translucency allows successful maturation over our protracted period of nurturing by close kin. This is due to the vital role played by emotional interactions in the normal cognitive and social development of Homo sapiens. (shrink)

In this paper I will discuss the role of national identity in the light of modern political and moral theories. My strategy here is threefold: firstly, I will present an overview of pre-modern theories of rights and duties of individuals, and then show how they fail to make sense of the notions of freedom and equality ; secondly, I will introduce modern political and moral theories as an outstanding alternative to those ones, given the paradigm of values established by modern (...) society; thirdly, I will argue against the supposed universality or objectivity of modern political and moral theories, taking into account the role of national identity.

Amartya Sen’s ethical theorizing helps feminists resolve the tensions between the claims of women’s particular perspectives and moral objectivity. His concept of ‘‘positional objectivity’’ highlights the epistemological significance of value judgments made from particular social positions, while holding that certain values may become widely shared. He shows how acknowledging positionality is consistent with affirming the universal value of democracy. This article builds on Sen’s work by proposing an analysis of democracy as a set of institutions that aims to intelligently utilize (...) positional information for shared ends. This epistemological analysis of democracy offers a way to understand the rationale for reserving political offices for women. From a political point of view, gendered positions are better thought of as an epistemological resource than as a ground of identity politics – that is, of parochial identification and solidarity.

This paper pictures emotions as able to provide reasons for action in so far as the beliefs and desires which make up reasons for action are constitutive elements of emotions themselves. It claims that the states of the world which prompt emotional attitudes “justify” them in so far as they render the beliefs constitutive of those attitudes true. Finally, it addresses the question what can make the desires or valuings ingredient to emotions appropriate to their objects.

One of the core issues in contemporary political philosophy is concerned with `political obligation.' Stated in an overly simplified way, the question being asked when one investigates political obligation is, "What, if anything, do citizens owe to their government and how are these obligations generated if they do exist?" The majority of political philosophers investigating this issue agree that a political obligation is a moral requirement to act in certain ways concerning political matters. Despite this agreement about the general nature (...) of what is being searched for, a broad division has arisen between political obligation theorists - there are some who take political obligations to actually exist and there are some who take there to be no general political obligation. While there is debate within the camp defending political obligation about what it is that generates the obligations, the common core of all "defender theories" is the fundamental idea that one has a moral requirement to support and obey the political institutions of one's country. Despite utilitarianism's status as one of the major ethical theories, historically, it has largely been dismissed by theorists concerned with political obligation. Within the contemporary debate it is generally accepted that utilitarianism cannot adequately accommodate a robust theory of political obligation. The overarching objective of this dissertation is to challenge this general dismissal of a utilitarian account and to build upon the two accounts which have been developed in offering a robust utilitarian theory of political obligation which can be considered a competitor to the other contemporary theories. However, as this utilitarian account of political obligation develops, the possibility will also emerge for a non-antagonistic relationship between the utilitarian theory on offer and the contemporary political obligation debate. The moral reasons posited by the traditional theories of political obligation can be included in and accommodated by my utilitarian account. The utilitarian account of political obligation can accept that there are many types of reasons explaining why broad expectations concerning individual and group behavior are created, and each type of reason can be understood as supporting the utilitarian claim that there are moral reasons for following the laws and supporting legitimate political authorities. Taken all together, my arguments will take the form of a three tiered response to the prevailing opinion that any utilitarian attempt to account for political obligations is doomed. The first tier contends that the utilitarian can consistently claim that there are moral reasons to follow the law. This is not a particularly strong claim, but it is one which has been denied by the vast majority of political theorists. The second tier of my argument addresses this apparent issue by contending that even the traditional deontological accounts of political obligation are not offering more than this. Lastly, it is contended that, given the contingent features of humans, the strength of the utilitarian political obligations is comparable to other accounts' analyses of the obligations. (shrink)

This thesis studies some philosophical and ethical issues that economic design raises. Chapter 1 gives an overview of economic design and argues that a crossfertilisation between philosophy and economic design is possible and insightful for both sides. Chapter 2 examines the implications of mechanism design for theories of rationality. I show that non-classical theories, such as constrained maximization and team reasoning, are at odds with the constraint of incentive compatibility. This poses a problem for non-classical theories, which proponents of these (...) theories have not addressed to date. Chapter 3 proposes a general epistemology of economic engineering, which is motivated by a novel case study, viz. the reform of a matching market for medical practitioners. My account makes use of causal graphs to explain how models allow encoding counterfactual information about how market outcomes change if the design of the market changes. The second part of the thesis examines ethical issues. In Chapter 4, I apply tools from matching theory to gain insights into the distribution of refugees, such as among countries of the European Union. There is an ethical trade-off between the fairness of matchings and their efficiency, and I argue that in this context, fairness is the morally weightier criterion. Chapter 5 deals with the ethics of kidney exchange. Against critics, I give two arguments for the implementation of kidney exchange programmes. The first argument is that they are instrumental in meeting a moral obligation, namely to donate effectively. The second is that kidney exchange may increase the motivation for altruistic donations, because the donation of one kidney may trigger > 1 life savings. The final chapter identifies questions for future research and it closes with some thoughts about the future trajectory of economic design. (shrink)

Eudaemonism is the common structure of the family of theories in which the central moral conception is eudaemonia , understood as "living well" or "having a good life." In its best form, the virtues are understood as constitutive and therefore essential means to achieving or having such a life. What I seek to do is to lay the groundwork for an approach to eudaemonism grounded in practical reason, and especially in instrumental reasoning, rather than in natural teleology. In the first (...) chapter, I argue that an approach based in natural teleology will not work. In the second, the claims of decision theory to be an adequate formal representation of instrumental reasoning are examined and found wanting. In the third, I develop an account of ordinary instrumental reasoning. In the fourth, I discuss the structure of eudaemonism, with the aim of showing that there is an intelligible and attractive doctrine that can be disentangled from the natural teleology. In the fifth, I sketch an argument showing that instrumental reasoning, as explicated in the third chapter, can bear on the selection of final and ultimate ends, and that it is plausible that the instrumental approach to moral theory that I am urging yields conclusions with a eudaemonistic structure. I also indicate directions for further development and exploration. (shrink)

This paper offers a critique of David Gauthier’s contractarian moral theory. I point out morally counter-intuitive implications of Gauthier’s theory – for example, with respect to societies with slavery or concerning the protection of animals – as well as theoretically unattractive features, such as the overly optimistic assumption of translucent agents. However, contractarian moral theories can be improved by correcting the theoretically unattractive features. Moreover, though some morally counter-intuitive implications cannot be avoided, whether we should accept these implications ultimately depends (...) on whether an instrumentalist account of practical reason is defensible and how morality relates to practical reason. Thus, contractarian moral theories cannot be refuted as easily as one might think at first. (shrink)

One of the fundamental tradeoffs underlying society is that between efficiency and equality. The challenge for institutional design is to strike the right balance between these two goals. Game-theoretic models of public-goods provision under ‘meritocratic matching’ succinctly capture this tradeoff: under zero meritocracy, theory predicts maximal inefficiency but perfect equality; higher levels of meritocracy are predicted to improve efficiency but come at the cost of growing inequality. We conduct an experiment to test this tradeoff behaviorally and make the astonishing finding (...) that, notwithstanding theoretical predictions, higher levels of meritocracy increase both efficiency and equality, that is, meritocratic matching dissolves the tradeoff. Fairness considerations can explain the departures from theoretical predictions including the behavioral phenomena that lead to dissolution of the efficiency-equality tradeoff. (shrink)
