Theory in Economics, Misc

F.A. Hayek essentially quit economic theory and gave up the phenomena of industrial fluctuations as an explicit object of theoretical investigation following the publication of his last work in technical economics, 1941’s The Pure Theory of Capital. Nonetheless, several of Hayek’s more methodologically-oriented writings bear important implications for economic phenomena, especially those of industrial fluctuations. Decisions (usually, for Hayek, of a political nature) taken on the basis of a “pretence” of knowledge impede the operation of the price system’s belief-coordinating function (...) and thereby contribute to episodes of economic disequilibrium. Moreover, this later account – which I call Hayek’s epistemic theory of industrial fluctuations – implies certain aspects of his earlier theory. The two accounts are connected in virtue of the role that ignorance and the limits of human knowledge play in each. Indeed, it turns out that – substantively, if not methodologically – Hayek’s early theory of the cycle is a special case of the more general epistemic account. (shrink)

The article addresses critical discourses pertaining to triangulation methodology as a step forward in dealing with policy formulation, particularly at the Bank of Sierra Leone. Alternative prescriptive measure like critical discourse analysis have been proposed as a means to the cutting head development in bridging the gap between orthodox and heterodox views of economic sciences investigations.

In this paper I analyse the problem of free will and determinism as it pertains to the Austrian School of Economics. I demonstrate that despite the fact they subscribe to the concept of causality,...

While the history and methodology of laboratory experiments in economics have been extensively studied by philosophers, those of field experiments have not attracted much attention until recently. What is the historical context in which field experiments have been advocated? And what are the methodological rationales for conducting experiments in the field as opposed to in the lab? This article addresses these questions by combining historical and methodological perspectives. In terms of history, we show that the movement toward field experiments in (...) economics has two distinct roots. One is the general orientation of medical and social sciences to evidence-based policy evaluation, which gave rise to randomized field experiments in economics. The other is an awareness of several methodological limitations of lab experiments in economics, which required practitioners to get out of the lab and into the field. In these senses, the movement is a consequence of influences from both outside and inside economics: the general evidence-based trend in policy science and an internal methodological development of experimental economics. In terms of methodology, we show that these two roots resulted in two somewhat different notions of “external validity” as methodological rationales of field experiment. Finally, we suggest that analysis of experiments as exhibits highlights a methodological strategy in which both strands complement each other. (shrink)

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

This article challenges the idea that competition was central to Adam Smith’s thinking by scrutinizing the concept’s role in Smith’s work, particularly The Wealth of Nations. We will understand Smith’s perspective better if we avoid reading later developments of the concept, particularly in economics, back into Smith’s times and writings. Conversely, I argue that the division of labor is the governing idea providing the basic organizational structure of Wealth of Nations. Clarifying (and demoting) the role of competition in Smith’s thinking (...) requires showing the centrality of the idea of the division of labor—the idea doing the major analytic work in his thinking. The argument contributes to recent reassessments of the scope and significance of Smith’s social theory and strengthens the view that his approach has more in common with historical and political sociology than with economics as currently configured. -/- .

(Expected) adverse effects of the ‘ICT Revolution’ on work and opportunities for individuals to use and develop their capacities give a new impetus to the debate on the societal implications of technology and raise questions regarding the ‘responsibility’ of research and innovation (RRI) and the possibility of achieving ‘inclusive and sustainable society’. However, missing in this debate is an examination of a possible conflict between the quest for ‘inclusive and sustainable society’ and conventional economic principles guiding capital allocation (including the (...) funding of research and innovation). We propose that such conflict can be resolved by re-examining the nature and purpose of capital, and by recognising mainstream economics’ utilitarian foundations as an unduly restrictive subset of a wider Aristotelian understanding of choice.

Research suggests that people tend to be fooled by randomness and mistake luck for skill, particularly when evaluating extreme performances. I argue that these predictable mistakes can be translated into a source of competitive advantage: informed managers can exploit others’ misperceptions of luck, such as by arbitraging in strategic factor markets. I then discuss limits to this arbitrage strategy due to social constraints: stakeholders may not be able to accurately evaluate performances and may disapprove atypical strategic activities, suggesting that only (...) strategists who are less sensitive to this “lemon problem” can take advantage of the resulting arbitrage opportunities. I conclude with a flowchart about when strategists should pursue this alternative source of strategic opportunity that turns the well- known biases on their head. (shrink)

Linguistic structures have recently started to attract attention from economists as determinants of economic phenomena. This paper provides the first comprehensive review of this nascent literature and its achievements so far. First, we explore the complex connections between language, culture, thought and behaviour. Then, we summarize the empirical evidence on the relationship between linguistic structures and economic and social outcomes. We follow up with a discussion of data, empirical design and identification. The paper concludes by discussing implications for future research (...) and policy. (shrink)

The book "Idealization XIV: Models in Science" offers a detailed ontological, epistemological and historical account of the role of models in scientific practice. The volume contains contributions of different international scholars who developed many aspects of the use of idealizations and models both in the natural and the social sciences. This volume is particularly relevant because it offers original contributions concerning one of the main topic in philosophy of science: the role of models in such branches of the sciences and (...) the humanities like comparative historical sociology, economics, history, linguistics and political philosophy. -/- Contributors are: Giacomo Borbone, Krzysztof Brzechczyn, Mieszko Ciesielski, Adam Czerniak, Xavier de Donato Rodríguez, José L.

As the title of this essay suggests, my concern is with the issue of what are economic models. However, the goal of the paper is not to offer an in-depth study on multiple approaches to modelling in economics, but rather to overcome the dichotomical divide between conceptualizing models as isolations and constructions. This is done by introducing the idea of economic models as believable worlds, precisely descriptions of mechanisms that refer to the essentials of the modelled targets. In doing so (...) I make use of the Woodward’s (2002) conceptualization of mechanisms. It is shown that such models do not offer the perfectly true descriptions of the actual world but justified beliefs about the modelled, precisely they aim at maximizing truth and minimizing falsity in a large body of belief about the real world. The analysis throughout the paper is supported by in-depth examination of the Varian’s (1980) model of sales that is here treated as a representative way of reasoning in neoclassical economics.

This short paper defends Oliver Williamson’s (1993) claim that talk of trust is ‘redundant at best and can be misleading’ when trust is defined as a form of calculated risk (p. 463). And this paper accepts Williamson’s claim that ‘Calculative trust is a contradiction in terms’ (p. 463). But the present paper defends a conception of genuine, non-calculative trust that is compatible with calculative considerations and calculative antecedents. This conception of trust creates space for genuine (non-calculative) trust relationships in the (...) economic order—in which calculative considerations and antecedents (most often) play an essential role.

This paper reconsiders Frank Ramsey's essay on subjective probability (1926) as a consistent way to articulate logic, rationality and knowledge. The first part of the essay builds an axiomatic theory of subjective probability based on ‘formal logic’, defining rationality as choice-consistency. The second part seems to open up different horizons: the evaluation of degrees of belief by ‘human logic’. Because of the interest Keynes (1931) had taken in ‘human logic’, it was considered to be a possible alternative to the formal (...) logic underlying the neoclassical theory of individual behaviour. The analysis of Ramsey's method in the entire paper, the relation between logic and rationality it constructs and the conception of uncertainty it reveals, lead me to note on the contrary that Ramsey's human logic was a complementary logic rather than an alternative to formal logic. Defining a standard to evaluate beliefs formation according to a frequentist criterion, it completes a normative representation of rationality which supports an original theory of knowledge that appears more in line with further developments of neoclassical methodology than with Keynesian economics.

Using an economic bargaining game, we tested for the existence of two phenomena related to social norms, namely norm manipulation – the selection of an interpretation of the norm that best suits an individual – and norm evasion – the deliberate, private violation of a social norm. We found that the manipulation of a norm of fairness was characterized by a self-serving bias in beliefs about what constituted normatively acceptable behaviour, so that an individual who made an uneven bargaining offer (...) not only genuinely believed it was fair, but also believed that recipients found it fair, even though recipients of the offer considered it to be unfair. In contrast, norm evasion operated as a highly explicit process. When they could do so without the recipient's knowledge, individuals made uneven offers despite knowing that their behaviour was unfair. (shrink)

By introducing elements of phenomenological philosophy to the analysis of human needs in economics; from Sartrean postulates as well as the nature and essence of individual’s needs, has been revealed a theorethical framework that serves to ponder human being’s existential behavior by means of their phenomenologic social choices and welfare. Defining a planning agent under strong assumptions of rationality and projective efficacious capabilities, the Arrow’s theorem has been proved for the economic agent aware of its finitude in this world.

The efficiency argument for profit maximization says that corporations and their managers should maximize profits because this is the course of action that will lead to an ‘economically efficient’ or ‘welfare maximizing’ outcome. In this paper, I argue that the fundamental problem with this argument is not that markets in the real world are less than perfect, but rather that the argument does not properly acknowledge the personal sphere. Morality allows each of us a sphere in which we are free (...) to pursue our personal interests, even if these are not optimal from the social point of view. But the efficiency argument does not come to terms with this feature of social life. (shrink)

Consider a sequence of outcomes of descending value, A > B > C >... > Z. According to Larry Temkin, there are reasons to deny the continuity axiom in certain ‘extreme’ cases, i.e. cases of triplets of outcomes A, B and Z, where A and B differ little in value, but B and Z differ greatly. But, Temkin argues, if we assume continuity for ‘easy’ cases, i.e. cases where the loss is small, we can derive continuity for the ‘extreme’ case (...) by applying the axiom of substitution and the axiom of transitivity. The rejection of continuity for ‘extreme’ cases therefore renders the triad of continuity in ‘easy’ cases, the axiom of substitution and the axiom of transitivity inconsistent.As shown by Arrhenius and Rabinowitz, Temkin's argument is flawed. I present a result which is stronger than their alternative proof of an inconsistency. However, this result is not quite what Temkin intends, because it only refers to an ordinal ranking of the outcomes in the sequence, whereas Temkin appeals to intuitions about the size of gains and losses. Against this background, it is argued that Temkin's trilemma never gets off the ground. This is because Temkin appeals to two mutually inconsistent conceptions of aggregation of value. Once these are clearly separated, it will transpire, in connection with each of them, that one of the principles to be rejected does not appear plausible. Hence, there is nothing surprising or challenging about the result; it is merely a corollary to Expected Utility Theory.

We find prejudices in favor of theory, as far back as there is institutionalized science. Plato and Aristotle frequented the Academy at Athens. That building is located on one side of the Agora, or market place. It is almost as far as possible from the Herculaneum, the temple to the goddess of fire, the patron of the metallurgists. It is ?on the other side of the tracks?. True to this class distinction, we all know a little about Greek geometry and (...) the teachings of the philosophers. Who knows anything about Greek metallurgy? Yet perhaps the gods speak to us in their own way. Of all the buildings that once graced the Athenian Agora, only one stands as it always was, untouched by time or reconstruction. That is the temple of the metallurgists. The academy fell down long ago. It has been rebuilt?partly by money earned in the steel mills of Pittsburgh. (Hacking 1983). (shrink)

Analytic induction (AI) is an interpretation of scientific method that emerged in early twentieth-century sociology and still has some influence today. Among the studies often cited as examples are Becker’s articles on marijuana use. While these have been given less attention than the work of Lindesmith on opiate addiction and Cressey on financial trust violation, Becker’s work has distinctive features. Furthermore, it raises some important and interesting issues that relate not only to AI but to social scientific explanation more generally. (...) These concern, for example, the presence and nature of causal systems in the social world, the relationship between historical and generalizing approaches, the character and role of social scientific theories, and how they are generated. In this article Becker’s research is examined in detail, and these issues explored through comparisons with the work of Lindesmith and Cressey. (shrink)

Much of economics is built on the assumption that individuals are driven by self-interest and economic development is an outcome of the free play of such individuals. On the few occasions that the existence of altruism is recognized in economics, the tendency is to build this from the axiom of individual selfishness. The aim of this paper is to break from this tradition and to treat as a primitive that individuals are endowed with the ‘cooperative spirit’, which allows them to (...) work in their collective interest, even when that may not be in their self-interest. The paper tracks the interface between altruism and group identity. By using the basic structure of a Prisoner's Dilemma game among randomly picked individuals and building into it assumptions of general or in-group altruism, the paper demonstrates how our selfish rationality interacts with our innate sense of cooperation. The model is used to outline circumstances under which cooperation will occur and circumstances where it will break down. The paper also studies how sub-groups of a society can form cooperative blocks, whether to simply do better for themselves or exploit others. (shrink)

Discussions of altruism occur in three importantly different contexts. During the past four decades, evolutionary theory has been concerned with the possibility that forms of behaviour labelled as altruistic could emerge and could be maintained under natural selection. In these discussions, an agent A is said to act altruistically towards a beneficiary B when A's action promotes the expected reproductive success of B at expected reproductive cost to A. This sort of altruism, biological altruism, is quite different from the kind (...) of behaviour important to debates about ethical and social issues. There the focus is on psychological altruism, a notion that is concerned with the intentions of the agent and that need have no connection with the spread of anyone's genes. Psychological altruists are people with other-directed desires, emotions or intentions (this is a rough preliminary characterization, to be refined below). Finally, in certain kinds of social scientific research, the important concept is that of behavioural altruism. From the outside, behavioural altruists look like psychological altruists, although their motives and preferences may be very different. (shrink)

Egoism and altruism are unequal contenders in the explanation of human behaviour. While egoism tends to be viewed as natural and unproblematic, altruism has always been treated with suspicion, and it has often been argued that apparent cases of altruistic behaviour might really just be some special form of egoism. The reason for this is that egoism fits into our usual theoretical views of human behaviour in a way that altruism does not. This is true on the biological level, where (...) an evolutionary account seems to favour egoism, as well as on the psychological level, where an account of self-interested motivation is deeply rooted in folk psychology and in the economic model of human behaviour. While altruism has started to receive increasing support in both biological and psychological debates over the last decades, this paper focuses on yet another level, where egoism is still widely taken for granted. Philosophical egoism is the view that, on the ultimate level of intentional explanation, all action is motivated by one of the agent's desires. This view is supported by the standard notion that for a complex of behaviour to be an action, there has to be a way to account for that behaviour in terms of the agent's own pro-attitudes. Psychological altruists, it is claimed, are philosophical egoists in that they are motivated by desires that have the other's benefit rather than the agent's own for its ultimate object. This paper casts doubt on this thesis, arguing that empathetic agents act on other people's pro-attitudes in very much the same way as agents usually act on their own, and that while other-directed desires do play an important role in many cases of psychologically altruistic action, they are not necessary in explanations of some of the most basic and most pervasive types of human altruistic behaviour. The paper concludes with the claim that philosophical egoism is really a cultural value rather than a conceptual feature of action. (shrink)

This paper argues that measurements of opportunity which focus on the contents of a person's opportunity set fail to capture open-ended aspects of opportunity that liberals should value. I propose an alternative conception of which does not require the explicit specification of opportunity sets, and which rests on an understanding of persons as responsible rather than rational agents. I suggest that issues of distributive fairness are best framed in terms of real income, and that meaningful measurements of real income are (...) possible if opportunity as mutual advantage is ensured.

This paper introduces a new approach to economic analysis. We show how to move from deductive to inductive modeling and thereby reunite economics with approaches used in the natural sciences. This paper presents the empathy-generosity-punishment model as an example of research based on observation, experimentation, and the elimination of alternatives. Inductive modeling in neuroeconomics allows the identification of the physiologic mechanisms that produce behavior. Unlike most neuroeconomics studies, we show how to establish causation by using drugs to manipulate brain activity. (...) This approach is demonstrated using three experiments that circumscribe the brain processes behind prosocial behavior. (shrink)

The purpose of the paper is to explore the potential for using fuzzy logic to analyse economic decision?making under Keynesian uncertainty, and in particular in circumstances where variety of opinion is important. Fuzzy logic is shown to apply where expectations may differ because the nature of the subject matter impedes any ?crisp? way of describing the underlying variables. The particular case of the speculative demand for money is considered, since it explicitly reflects variety of opinion as to whether interest rates (...) are ?high? or ?low? (shrink)

Are foundations of models of ambiguity-sensitive preferences too flawed to be usefully applied to economic models? Al-Najjar and Weinstein (2009) say such is indeed the case. In this paper, first, we point out that many of the key arguments by Al-Najjar and Weinstein do not apply to quite a few of the ambiguity preference models of more recent vintage, and therefore to that extent do not undermine the foundational aspects or applicability of ambiguity models in general. Second, we argue the (...) focus in that paper on Ellsberg examples is an overly narrow concern; the Ellsberg examples have their uses but they are not the best context to understand why reasonable real-world agents may find acting in an ambiguity-sensitive manner normatively or prescriptively appealing. Finally, normative considerations aside, we submit that Al-Najjar and Weinstein are unduly dismissive of the power of such preferences to provide illuminating positive analyses of economic phenomena.

An article by Luigino Bruni and Robert Sugden published in this journal argues that market relations contain elements of what they call ‘fraternity’. This Response demonstrates that my own views on interpersonal relations and markets – which originated in the feminist analysis of caring labour – are far closer to Bruni and Sugden's than they acknowledge in their article, and goes on to discuss additional important dimensions of sociality that they neglect.

In this paper I study how the theoretical categories of consumption theory were used by Milton Friedman in order to classify empirical data and obtain predictions. Friedman advocated a case by case definition of these categories that traded theoretical coherence for empirical content. I contend that this methodological strategy puts a clear incentive to contest any prediction contrary to our interest: it can always be argued that these predictions rest on a wrong classification of data. My conjecture is that this (...) methodological strategy can contribute to explain why Friedman’s predictions never generated the consensus he expected among his peers. (shrink)

Keynesian concepts of probability and uncertainty emphasize the basis of knowledge available to economic decision makers. Conditions of uncertainty, which involve missing evidence or doubtful arguments, are distinguished from probable risk. Beyond this, on the basis of the claim that the future is yet to be created, some authors argue for further distinctions among different kinds of uncertainty. The paper reviews this particular argument, distinguishing it from Keynesian uncertainty theory generally, and provides a critique of its implication that, due to (...) innovation, objective distributions of possible events do not generally exist at the time of economic decisions.

The power of economic thinking can be explained by seven core principles which include accountability, investments, economy, incentive, freedom of choice, nondiscrimination and one price. By understanding and incorporating these principles, better decisions will be made on individual, corporate and government levels. To explain this thesis, the author offers analyses of key economists who have changed their views over time, an examination of major domestic and international issues, and an explanation of how economists can predict which politicians will be successful.

In this short note I speculate about the various ways in which the study of neurological aspects of decision making could be fruitful for economic modelling.

How should we define the feasible set? Even when individuals agree on facts and values, as traditionally construed, different views on feasibility may suffice to produce very different policy conclusions. Focusing on the difficulties in the feasibility concept may help us resolve some policy disagreements, or at least identify the sources of those disagreements. Feasibility is most plausibly a matter of degree rather than of kind. Normative economic reasoning therefore faces a fuzzy social budget constraint. Iterative reasoning about feasibility and (...) desirability may help us overcome these problems. (shrink)

We propose a general framework for integrating theory and empiricism in human evolutionary ecology. We specifically emphasize the joint use of stochastic nonlinear dynamics and information theory. To illustrate critical ideas associated with historical contingency and complex dynamics, we review recent research on social preferences and social learning from behavioral economics. We additionally examine recent work on ecological approaches in history, the modeling of chaotic populations, and statistical application of information theory.

Economic sociologists have developed and applied theories and concepts in close connection with broadly economic phenomena, including, recently, embeddedness and actor network theory. Key to these theories is understandings of action given uncertainty in which actors develop calculative capabilities, and an emphasis on markets with boundaries and interstices as essential properties. This article reflects upon the connections between Parsons' and Smelser's economic sociology and that of contemporary authors including Granovetter, Callon and White. As a strange other to economics and to (...) sociology, economic sociology can develop research questions in considering arbitrage generally, rather than only restricted to financial markets.

The concept of tacit knowledge has come a long way from its origins in Michael Polanyi's work and its championing by Hayek and other Austrian economists. It is now widely, even routinely, cited not only in Austrian economics, but also in institutional economics work, industrial economics and economic geography. Further, rather than being viewed as a hypothesis requiring conceptual clarification and empirical testing, the concept of tacit knowledge is almost invariably treated as established, even incontrovertible, virtually as a fact. Conceptual (...) disputes over tacit knowledge have instead focused on the boundaries between codifiable and tacit knowledge. Here we draw upon a critique of tacit knowledge and tacit rule following from the social philosophy literature that has not been considered in the economics literature hitherto. In brief, this critique argues that the concept of tacit knowledge is merely a term given to a phenomenon the observer does not understand; as such, it has no explanatory content. Through a philosophical examination of rule following, this critique further argues that the concept of agents tacitly following rules is highly problematic, not to say implausible. (shrink)

Why are people interested in money? Specifically, what could be the biological basis for the extraordinary incentive and reinforcing power of money, which seems to be unique to the human species? We identify two ways in which a commodity which is of no biological significance in itself can become a strong motivator. The first is if it is used as a tool, and by a metaphorical extension this is often applied to money: it is used instrumentally, in order to obtain (...) biologically relevant incentives. Second, substances can be strong motivators because they imitate the action of natural incentives but do not produce the fitness gains for which those incentives are instinctively sought. The classic examples of this process are psychoactive drugs, but we argue that the drug concept can also be extended metaphorically to provide an account of money motivation. From a review of theoretical and empirical literature about money, we conclude that (i) there are a number of phenomena that cannot be accounted for by a pure Tool Theory of money motivation; (ii) supplementing Tool Theory with a Drug Theory enables the anomalous phenomena to be explained; and (iii) the human instincts that, according to a Drug Theory, money parasitizes include trading (derived from reciprocal altruism) and object play.

This paper focuses on the implications for the economic analysis of growth and innovation in relation to the NSI concept being part of the evolutionary research programme. We show that the modern evolutionism associates descriptive and theoretical works following specific methodological reasons. It is then argued that the NSI concept has a particularly important place within the evolutionary research programme, because it challenges and is challenged by the new neoclassical theories of growth concerning the explanation of the convergence/divergence process among (...) the developed economies. It is also very powerful in order to elaborate arguments for technological policies. In addition, its evaluation cannot be disconnected from its theoretical content. We illustrate why the NSI will not be helpful for the neoclassical theories of growth because the assumptions it relies on are not be accepted by these theories. (shrink)

This paper is a critical reflection on the use of monetary incentives in economic experiments. The argument is that incentives have their effect through their influence on one or more of three factors: (1) cognitive exertion; (2) motivational focus; (3) emotional triggers. I suggest that these effects can often be achieved without monetary incentives, and incentives are not even guaranteed to achieve those effects. There are also disadvantages to requiring the use of incentives in experiments. The paper concludes by suggesting (...) there is no basis for requiring the use of real incentives to do experimental economics. (shrink)

Following James Rule and Colin Clark, a single?theory?driven approach to scientific inquiry which focuses on testing particular theories can be distinguished from an explanation?driven approach which is open to all observations and whose results do not cease to have value with the passing of a particular theory. Several ?decision points? in the historiography of the Great Depression are examined and it is shown that the decisions made at each point reflect a single?theory?driven orientation. It is argued that the single?theory?driven approach (...) likely characterizes other fields of Economics, and also that this paper's method of applying a ?test? to various decision points in the evolution of economic thought is of widespread utility. The likely cost of a single?theory?driven bias in terms of our collective understanding is discussed. (shrink)

When viewed as a question of distributive justice the evaluation of workfare typically reflects exclusively on the distribution of income: do the physically capable have a justified claim for state support, or is it fair to demand from those who do work to subsidise this support? Rarely is workfare appraised in terms of how it affects other parties such as employers or other workers, and on the structural effects the pattern of incentives it generates brings about, or as an issue (...) of distributive justice related to a more extensive range of objects of distribution such as access to pleasing jobs. -/- We propose to evaluate workfare by looking at its effects more broadly: (1) we discuss and dismiss on empirical grounds the two most common arguments in favour of workfare, namely that workfare develops self-reliance among participants and it is more economical in the use of altruism among taxpayers. (2) We suggest that workfare focuses on work as a burden and as a means to income, ignoring other beneficial aspects that are conducive to the worker’s self expression. These other benefits are distributed unevenly between two main groups: the privileged well off and the disadvantaged. (3) we argue that workfare functions as a mechanism to preserve these privileges to one class of workers at the expense of another. Or, to put it the other way, the payment of unconditional welfare to the long term unemployed might be justified as one method of mitigating unjustified privileges. (shrink)
