Abstract: The paper argues that mainstream economics and mainstream philosophy of natural science had much in common during the period 1945-1965. It examines seven common features of the two fields and suggests a number of historical developments that might help explain these similarities. The historical developments include: the Vienna Circle connection, the Samuelson-Harvard-Foundations connection, and the Cold War operations research connection.

Science depends on judgments of the bearing of evidence on theory. Scientists must judge whether an observation or the result of an experiment supports, disconfirms, or is simply irrelevant to a given hypothesis. Similarly, scientists may judge that, given all the available evidence, a hypothesis ought to be accepted as correct or nearly so, rejected as false, or neither. Occasionally, these evidential judgments can be made on deductive grounds. If an experimental result strictly contradicts a hypothesis, then the truth of (...) the data deductively entails the falsity of the hypothesis. In the great majority of cases, however, the connection between evidence and hypothesis is non-demonstrative, or inductive. In particular, this is so whenever a general hypothesis is inferred to be correct on the basis of the available data, since the truth of the data will not deductively entail the truth of the hypothesis. It always remains possible that the hypothesis is false even though the data are correct. (shrink)

This article addresses some recent tendencies in economic methodology defined as a philosophy of science for economics. I review the problem of normative/positive distinction in methodology and argue that normativity in its past forms is intolerable today but is, at the same time, indispensable for methodological inquiry. Using recent texts by Mirowski and Nik-Khah and by Alexandrova and Northcott on the applications of auction theory as a case study, I compare in more detail various approaches to economic methodology inspired by (...) the science and technology studies (STS) and philosophy of science literatures, respectively. On the basis of this comparison, I show that the STS programme in economic methodology may prove fruitful in the future, but there is still a place for more aprioristic philosophical thinking. Methodology and history of economics also play a fundamental role that goes beyond the descriptive analysis of STS and offer conceptual clarification paired with normative concerns provided by philosophers of science.

The use of unrealistic assumptions in Economics is usually defended not only for pragmatic reasons, but also because of the intrinsic difficulties in determining the degree of realism of assumptions. Additionally, the criterion used for evaluating economic models is associated with their ability to provide accurate predictions. This mode of thought involves –at least implicitly– a commitment to the existence of unvarying invariant factors or regularities. Contrary to this, the present paper presents a critique to the use of invariant knowledge (...) in economics. One reason for this analysis lies in the fact that economic phenomena are not compatible with the logic of invariance, but with the logic of "possibility trees" or "open-ended results". The other reason is that the use of invariant knowledge may entail both external validity problems and negative exposures to a "black swan". Alternatively, an approach where models are understood as possible scenarios is proposed. It is argued that the realism of assumptions is crucial here, since it helps to ascertain the degree of resemblance between the different models and the target system. (shrink)

In his "A New Program for Philosophy of Science?", Ronald Giere expresses qualms regarding the critical and political projects I advocate for philosophy of sciencethat the critical project assumes an underdetermination absent from actual science, and the political project takes us outside the professional pursuit of philosophy of science. In reply I contend that the underdetermination the critical project assumes does occur in actual science, and I provide a variety of examples to support this. And I contend that the political (...) project requires no more than what other academic fields even in science studies are already providing. (shrink)

Le projet philosophique puise ses sources dans la volonté de proposer une explication rationnelle des phénomènes naturels et culturels qui constituent le monde dans lequel l’être humain prend place. Il a servi de trame culturelle à l’Occident et amené le déploiement d’appareils conceptuels où l’on distingue théorie et pratique. On doit toutefois reconnaître qu’une philosophie théorique peut avoir une portée pratique et l’inverse, puisque toute pratique suppose un ancrage théorique pour légitimer la connaissance et les systèmes normatifs à partir desquels (...) les explications sont avancées. Cela fait dire à certains que la distinction est désormais surannée et qu’une théorie philosophique réunifiée s’impose. Que l’on soit tenant de la tradition ou des nouvelles approches, la philosophie pratique s’impose désormais comme un passage obligé pour réfléchir les problèmes et articuler de nouvelles théories faisant écho à l’état actuel de notre monde. Le présent ouvrage revient sur la notion de philosophie pratique afin d’en faire voir les différentes acceptions et manières de la mobiliser pour réfléchir à des problèmes actuels. (shrink)

The critique of philosophical foundations of neoclassical economics is significant, because of its hegemony on economic education and research programs in Iran and worldwide academies. Due to an epistemological fallacy, methodological individualism plays a prominent role in the philosophy of economic; since the ontological aspects of economy are reduced to methodological considerations. Accordingly, critique of methodological individualism is regarded as the main entry for philosophical analysis of neoclassical economics. This article aims to analyze and appraise the methodological individualism from critical (...) realism’s point of view. Critical realism is taken as a stand for criticizing methodological individualism, because critical realism and neoclassical economics as a positive approach to economics, both share a realistic worldview. The critical realism’ critique of methodological individualism is bases on analyzing the concepts of formalism, syllogism, social atomism, isolation and reduction. From critical realism’ point of view because of unrealistic postulations of methodological individualism, neoclassical economics is turned to an abstract and deductive science such as mathematics with a low potentiality of explanation.

Despite the conclusions from the contemporary philosophy of science, many economists cherish the ideal of positive science. Therefore, value-free economics is still the central paradigm in economics. The first aim of the paper is to investigate economics' axiomatic assumptions from an epistemological perspective. The critical analysis of the literature shows that the positive-normative dichotomy is exaggerated. Moreover, value-free economics is based on normative foundations that have a negative impact on individuals and society. The paper's second aim is to show that (...) economics' normativity is not a problem because the discussion concerning values is possible and unavoidable. In this context, Weber and other methodologists are investigated. The conclusion of the paper is that science can thrive without strict methodological rules thanks to institutional mechanisms. Therefore, economists could learn from artists who accept the world without absolute rules. This perspective opens the possibility for methodological pluralism and normative approaches. (shrink)

The books’ goal is to answer the question: Do the weaknesses of value-free economics imply the need for a paradigm shift? The author synthesizes criticisms from different perspectives (descriptive and methodological). Special attention is paid to choices over time, because in this area value-free economics has the most problems. In that context, the enriched concept of multiple self is proposed and investigated. However, it is not enough to present the criticisms towards value-free economics. For scientists, a bad paradigm is better (...) than no paradigm. Therefore, the author considers whether value-based economics with normative approaches such as economics of happiness, capability approach, libertarian paternalism, and the concept of multiple self can be the alternative paradigm for value-free economics. This book is essential reading to everyone interested in the current state of economics as a discipline. (shrink)

Since the early days of economics, the rationality principle has been a core element of economic theorizing. It is part of almost any theoretical framework that economists use to generate knowledge. Despite its central role, the principle’s epistemic status and function continue to be debated between empiricists and rationalists, and a clear winner is yet to emerge. One point of contention is that we cannot explain the principle’s special status in light of clear evidence against its empirical validity and the (...) continuous conceptual changes it undergoes. In this paper, I argue that we should think of the rationality principle as a functional a priori principle along the lines of a pragmatic theory of constitutive elements recently put forward by David Stump. Such an approach would explain the principle’s persistence and changing status. More generally, the pragmatic theory of constitutive elements in science offers a viable alternative to rationalism and empiricism that allows for approaching the debate about the status and function of the rationality principle in economics. It provides a new framework and starting point to think about the usefulness of a central first principle in economics in a constructive way. (shrink)

This paper is part of the general debate about the need to rethink economics as a human discipline using a heuristic to describe its object, about the need to explicitly reject the positivistic approach in neoclassical economics, and about the urgency to adopt a different methodology, grounded on a realistic set of initial assumptions able to cope with the complexity of the decision making process. The aim of this paper is to show the use of Occam's razor in the economic (...) debate around realism in economic modelling. Occam's razor can be intended as a principle of logic that emphasises simplicity, or as a heuristic tool that emphasises parsimony. Neoclassical economists, such as Samuelson, have explicitly used Occam's razor as a logical principle to highlight the strict logic and simplicity of neoclassical economics; neoclassical models, however, are based on unrealistic assumptions. Some approaches of heterodox economics, au contraire, have used Occam's razor as a powerful heuristic tool to emphasise parsimony, building up models grounded on realistic initial assumptions and capable of embedding complexity into the general explanation of economic behaviour, as in Simon's bounded rationality (1955; 1957) and Hayek's notion of human rationality (1948; 1952; 1974) and cultural and social evolution (1967; 1978).

The emergence of transaction cost economics in the early 1970s with Oliver Williamson's successful reconciliation of the so-called neoclassical approach with Herbert Simon's organizational theory can be considered an important part of the first cognitive turn in economics. The development of TCE until the late 1980s was particularly marked by treating the firm as an avoider of negative frictions, i.e., of transaction costs. However, since the 1990s TCE has been enriched by various approaches stressing the role of the firm in (...) creating positive value, e.g., the literature on modularity. Hence, a second cognitive turn has taken place: the firm is no longer only seen as an avoider of negative costs but also as a creator of positive knowledge. (shrink)

While I am in broad agreement with the main thrust of Fine’s and Milonakis’s argument, I pose sixteen questions for them. The first ten questions relate to the history of economic thought ; substantive issues of economic theory ; methodological and philosophical matters ; and the other social sciences. I conclude by asking six questions about the ‘old’ and ‘new’ economics imperialism, the prospects for mainstream economics, and the precise nature of the political-economy alternative that Fine and Milonakis propose. Is (...) it simply Marxian political economy in disguise? (shrink)

This is a comprehensive anthology of works concerning the nature of economics as a science, including classic texts and essays exploring specific branches and schools of economics. Apart from the classics, most of the selections in the third edition are new, as are the introduction and bibliography. No other anthology spans the whole field and offers a comprehensive introduction to questions about economic methodology.

This paper discusses the development of the field of economic methodology during the last few decades emphasizing the early influence of the "shelf" of Popperian philosophy and the division between neoclassical and heterodox economics. It argues that the field of methodology has recently adopted a more naturalistic approach focusing primarily on the "new pluralist" subfields of experimental economics, behavioral economics, neuroeconomics, and related subjects.

The present work was intended originally as a chapter for my January 2006 Ph.D dissertation, but now is essentially a 'working paper.' As is well known, economists make a number of abstract and unrealistic assumptions, such as for example characterising the economic agent as a rational maximiser. The present paper is concerned with assessing the methodological status of every-day common-sense observations in relation to such abstract and unrealistic assumptions. Following Popper and Hume, I propose a theoretical framework in which to (...) understand 'common sense.' I then argue that common-sense acts as a 'guide' assessing the value of theoretical work, that theoretical contributions that are based on premises or arrive at conclusions that diverge to a greater degree should require a higher level of justification, and that any common-sense observation about the real world should be admissable as a starting point for theoretical investigation and elaboration and any successful theory should be accountable to common-sense observations.

This paper evaluates Nancy Cartwright’s critique of economic models. Cartwright argues that economics fails to build relevant “nomological machines” able to isolate capacities. In this paper, I contend that many economic models are not used as nomological machines. I give some evidence for this claim and build on an inferential and pragmatic approach to economic modeling. Modeling in economics responds to peculiar inferential norms where a “good” model is essentially a model that enhances our knowledge about possible worlds. As a (...) consequence, models and experiments are very different knowledge-producing devices, at least in economics. (shrink)

Normative research has nearly vanished from the academic ‘mainstream’ in accounting. Due to its prescriptive and value-driven approach, normative accounting research has been stigmatized as being unscientific and largely replaced by positive studies. We put this stigma into perspective. We first conceptualize the ‘positive-normative’ distinction and identify this dichotomy in accounting research history. We then challenge the dogmatic confinement of science to descriptive (positive) approaches. Moreover, we debate the basic conditions for normative accounting research and conclude that methodological and epistemological (...) pluralism in accounting research may help address a wide range of potential research questions. We point out that normative research approaches are essential in an applied science such as accounting, lest practical implications and prescriptions are to be the exclusive domain of accounting practice.

In this article, I examine Luhmann’s, Bunge’s and others’ views on emergence, and argue that Luhmann’s epistemological construal of emergence in terms of Totalausschluss (total exclusion) is both ontologically flawed and detrimental to an appropriate understanding of the distinctive features of social emergence. By contrast, Bunge’s rational emergentism, his CESM model, and Wimsatt’s characterization of emergence as nonaggregativity provide a useful framework to investigate emergence. While researchers in the field of social theory and sociology tend to regard Luhmann as the (...) sole representative of systems theory, the latter has been characterized by its diversity, and the writings of such systems theorists as Mario Bunge deserve more (critical) attention from social researchers than they receive at present. Finally, this article suggests that the perennial debate over methodological individualism and holism in social science may make real progress if such ambiguous terms as reduction and reductionism are elucidated before they are employed.

Being scientific research a process of social interaction, this process can be studied from a game-theoretic perspective. Some conceptual and formal instruments that can help to understand scientific research as a game are introduced, and it is argued that game theoretic epistemology provides a middle ground for 'rationalist' and 'constructivist' theories of scientific knowledge. In the first part , a description of the essential elements of game of science is made, using an inferentialist conception of rationality. In the second part (...) , some ideas for the reconstruction of case studies are introduced, and applied to one example: Latour's analysis of Joliot's attempt to build an atomic bomb. Lastly, in the third part , a formal analysis of the constitution of scientific consensus is offered. (shrink)

This paper draws a connection between recentdevelopments in naturalized philosophyof science and the Buchanan research programin economics. Economic approaches innaturalized philosophy of science canbe combined to form an economic philosophy ofscience. After giving an overview of someof these approaches, I lay out the fundamentalsof the Buchanan research program. I arguethat its main elements are a theory of interactionsand a normative foundation in consensus whichhelp to answer some important criticismsof economic philosophy of science.

The goal of the article is to substantiate that despite the criticism the paradigm in economics will not change because of the axiomatic assumptions of value-free economics. How these assumptions work is demonstrated on the example of Gary Becker’s economic approach which is analyzed from the perspective of scientific research programme. The author indicates hard core of economic approach and the protective belt which makes hard core immune from any criticism. This immunity leads economists to believe that they are objective (...) scientists and, consequently, it results in epistemological hubris. Due to its tautological nature, economic approach is considered to be a degenerative programme. This conclusion is extended on value-free economics. In spite of these problems, many economists still believe in positive economics and they dismiss normative approaches. It has a negative influence on people. The conclusion of the article is that thanks to axiomatic assumptions economists do not have objective and ironclad methodology and they should accept normative values in their research. (shrink)

: Eponymic honor is a common form of professional recognition in economics, as it is in other sciences. There also seems to be convincing evidence that individuals exposed to economic theory behave less cooperatively and more self-interestedly than individuals who have not been exposed to such economic ideas. Taken together these two facts would seem to suggest that the history of economic thought would be a history of rather contentious priority fights. If economists generally behave in self-interested and non-cooperative ways, (...) and having your name attached to a particular result serves one’s professional self-interest, then economists should be quick to fight for these eponymic honors. This means that economists should be continually involved in sordid disputes about who does, and who does not, get credit for various economic discoveries. The paradox is that such priority fights do not exist in economics. The paper examines absence of such disputes from a Mertonian perspective. (shrink)

We focus on the debate on the external validity of lab results in the area of experimental economics. More specifically, we focus on Colin Camerer’s and John List’s views, who postulate opposite positions on the issue. The problem is that they partially analyze the same empirical evidence and draw from it opposite conclusions. The goal of this work is to analyze such empirical evidence to try to explain the difference in interpretation of results. We argue that the dispute in interpretations (...) can be expressed in terms of difference of criteria used to determine external validity. From our analysis we propose the formulation of different types of external validity. (shrink)

Different kinds of collectives help to coordinate between individuals and social groups to solve distribution problems, supply goods and services, and enable individuals to live fulfilling lives. Collectives, as part of the process of socialization, contribute to the normalization of behaviors, and consequently, structure our ability to be self-reflective autonomous agents. Contemporary philosophy of action models characterize collective action as the product of individuals who have the proper motivations to perform cooperative activities (bottom-up); or they begin with the social-level phenomena (...) and explain this in terms of individual actions and the mental states that motivate them (top-down). One general goal of this project is to show how and why both of these approaches through focusing solely on the individuals involved fail to capture and account for important types of group actions: those of economic group agents. Group agents, one kind of organized collective, are unique in that they have the potential to develop group-level decision-making processes that result in the capacity of the group to engage in practical reasoning. Because of this capacity, group agents can be stable and respond to reason--capacities we would not expect from other kinds of collectives. Inasmuch as we value the possibility of influencing the reflexive dynamics that perpetuate social institutions, understanding the range of organization structures and their agential capacities will open up the possibility of altering the course of those dynamics toward more just systems of organization. Understanding what kinds of group agents currently operate within the systems of organizations that make up social institutions is the first step in determining how to move toward developing group agents that are also moral agents. By analyzing how different systems of constraint--inside and outside the firm--inform one another to influence the possibility of design and the group's possibilities for action, I use Christian List and Philip Pettit's account of group agency as a springboard to develop a more adequate account of how structure influences and constrains the possibilities of economic group agents in non-idealized circumstances (i.e. this world, with our history). My chapters include 1) a taxonomy of organization structures and an analysis of how a narrow conception of organization structure in jurisprudence can lead to systems of constraint that limit the rights and freedoms of individuals even as it seeks to extend them, 2) an evaluation of the popular accounts of collective action (cf. Raimo Tuomela, 1997; Michael Bratman, 1993, 1997, 2009; and Christian List and Philip Pettit, 2011) that could be made to accommodate the actions of certain kinds of economic associations, 3) an exploration of the standards of evaluation that influence these powerful group agents, and how these standards limit the economic group agent's capacity to engage in moral reasoning, and 4) an analysis of the group agent's reasoning capacity and the internal mode of interaction between group agent and group members that perpetuate group agency. I argue that we can understand group agents that have the capacity to be moral agents as the products of a particular kind of decision-making process within an organization's structure. The decision-making process, together with the organization structure and group member support, produces and sustains judgments and actions at the level of the group that cannot be reduced to the beliefs and actions of particular members. In this way, the group displays a systematic unity of actions based on its own judgments. That is, the group exhibits agency. Moral group agents exhibit more than practical reasoning; they also demonstrate the capacity for critical reflection upon the ends they pursue. Member buy-in promotes a tight connection between group members and their role in bringing about and sustaining group agency, and is the foundation of the group agent. Without a holistic organization structure, a member's personal identities could undermine group aims, thereby undermining group agency. Group moral agency, I argue, begins with promoting an organizational way of life conducive to collective flourishing and respect for members. (shrink)

The dramatic and ongoing changes in the funding of science have stimulated interest in an economics of scientific knowledge, which would investigate the effects of these changes on the scientific enterprise. Hands has previously explored the lessons for such an ESK from the existing precedent of the sociology of scientific knowledge. In particular, he examines the philosophical problems of SSK and those that any ESK in its image would face. This paper explores this argument further by contending that more recent (...) literature in SSK exposes even deeper philosophical problems than those identified by Hands. Meaning finitism has emerged as the philosophical core of SSK. An examination of the profound problems with this position is used to show that an underlying extensionalism is the root of SSK's intractable philosophical difficulties, and to illustrate the entirely different approach of a critical philosophy that is advocated in its place. In this way, the project of an ESK is shown to depend upon a critical philosophy. (shrink)

Economists reason causally. Like many other scientists, they aim at formulating justified causal claims about their object of study. This thesis contributes to our understanding of how causal reasoning proceeds in economics. By using the research on the causes of unemployment as a case study, three questions are adressed. What are the meanings of causal claims? How can a causal claim be adequately supported by evidence? How are causal beliefs affected by incoming facts? In the process of answering these semantic, (...) epistemic and dynamical questions, the richness of causal reasoning in economics is brought to the foreground. In the part on semantics, it is argued that the meaning of causal generalizations in policy-oriented economics is best captured by using the concept of ‘inferential relation’ rather than the one of ‘referential relation’. This part contributes to develop an inferentialist semantics by distinguishing among types of inferential relations. In the part on epistemology, it is argued that justification in sciences like economics often relies, and ought to rely, on evidential variety―i.e. the combination of evidence from multiple sources. An interpretation of independence among evidential sources is offered: two evidential sources are fully independent if and only if the reasons why they would be unreliable do not overlap. It is then shown that the variety-of-evidence thesis does not hold under extreme circumstances. The part on dynamics focuses on deviant-case study. A storyline is provided for what deviant-case study aims at and how it proceeds in what is characterized as an ‘eclectic science’. (shrink)

How can we use models to understand real phenomena if models misrepresent the very phenomena we seek to understand? Some accounts suggest that models may afford understanding by providing causal knowledge about phenomena via how-possibly explanations. However, general equilibrium models, for example, pose a challenge to this solution since their contribution appears to be purely mathematical results. Despite this, practitioners widely acknowledge that it improves our understanding of the world. I argue that the Arrow–Debreu model provides a mathematical how-possibly explanation (...) which establishes claims of mathematical dependence. The account developed reveals how mathematical knowledge can inform claims about the world, allow ‘what-if-things-had-been-different’ inferences, and thus improve our understanding. (shrink)

Recent developments in economics and the science of law emphasize their cooperation for a better understanding of social structures and interactions, an effective application of social scientific knowledge and a rational evaluation and implementation of social norms. There are, however, difficult methodological problems in this endeavor: Whereas economics is mainly (with the exception of welfare economics) an empirical science which collects information about economic activities and the functioning of the economic system, the science of law is a normative discipline aiming (...) at solving social conflicts and establishing rational principles for judicial decisions. In this paper, we suggest a three-level scheme for the interdisciplinary cooperation of law and economics, addressing the different problems that positive and normative economics face as they apply economic knowledge to legal matters. Economic analysis of law is proposed as a model for a general transformation of the traditionally hermeneutical jurisprudence into an analytic-normative science of law based on theoretical expectation (explanation) and the rational evaluation of the consequences of legal rules and principles.

The main scope of this article is to introduce Spiethoff's economic styles approach to economists outside the German-speaking scientific community. It also provides a contemporary (new) reading and interpretation of this approach, especially regarding the methodology Spiethoff used in his research. Essentially, it will be shown that Spiethoff applies a kind of 'abductive' thinking that is usually ignored. Especially in the recent debate about pluralism in economics, the dichotomy of induction and deduction excludes the concept of abduction. Against this background, (...) the article highlights what Spiethoff's economic styles approach could add to the current debate regarding pluralism in economics. (shrink)

In the methodology of scientific research programs (MSRP) there are important features on the problem of prediction, especially regarding novel facts. In his approach, Imre Lakatos proposed three different levels on prediction: aim, process, and assessment. Chapter 5 pays attention to the characterization of prediction in the methodology of research programs. Thus, it takes into account several features: (1) its pragmatic characterization, (2) the logical perspective as a proposition, (3) the epistemological component, (4) its role in the appraisal of research (...) programs, and (5) its place as a value for scientific research. -/- The notion of “novel facts” is highly relevant in his conception, where several aspects are involved: the directions of novel facts, the different kinds of novelty, and the transition from six possible options of “novel facts” to four choices. Thereafter, the prediction of novel facts as the criterion of appraisal is considered. On the one hand, this requires analyzing the theoretical, empirical, and heuristic possibilities of appraisal; and, on the other, whether there is an overemphasis on the role of prediction in methodology of scientific research programs. As a consequence, there is an analysis of Lakatos’ criterion of appraisal in MSRP and economics. (shrink)

In recent times, realism in economic methodology has increasingly gained importance. Uskali Mäki and Tony Lawson are the best-known realists within the discipline and even though their approaches are fundamentally different, both provide pragmatic defences of realism by claiming anti-realism to be the reason for the low quality of economic models. My paper will show that a pragmatic defence of realism is untenable and furthermore, I will show that for both Mäki's and Lawson's normative ideas there is no need for (...) realism. (shrink)

This thesis attempts to justify a normative role for methodology by sketching a pragmatic way out of the dichotomy between two major strands in economic methodology: empiricism and postmodernism. I discuss several methodological approaches and assess their aptness for theory appraisal in economics. I begin with the most common views on methodology and argue why they are each ill-suited for giving methodological prescriptions to economics. Then, I consider positions that avoid the errors of empiricism and postmodernism. I specifically examine why (...) the two major strands of methodological criticism fail to give helpful methodological advice to economists and sketch out a pragmatic approach that can do this.
