Essential Microeconomics is designed to help students deepen their understanding of the core theory of microeconomics. Unlike other texts, this book focuses on the most important ideas and does not attempt to be encyclopedic. Two-thirds of the textbook focuses on price theory. As well as taking a new look at standard equilibrium theory, there is extensive examination of equilibrium under uncertainty, the capital asset pricing model, and arbitrage pricing theory. Choice over time is given extensive coverage and includes (...) a basic introduction to control theory. The final third of the book, on game theory, provides a comprehensive introduction to models with asymmetric information. Topics such as auctions, signaling and mechanism design are made accessible to students who have a basic rather than a deep understanding of mathematics. Examples and diagrams are used to illustrate issues as well as formal derivations. (shrink)

My philosophical case study concerns textbook presentations of the theory of demand. Does this theory contain anything more than just a collection of tautologies? In order to determine its empirical content, it must be viewed holistically. But then, the theory implies false factual claims. We can avoid this result by embracing the theory’s normative character. The resulting consequences will be illuminated with the new autodetermination thesis recently proposed in the philosophy of physics by Oliver Timmer. Applying his ideas to the (...) theory of demand reveals that the statements of this discipline simultaneously concern both values and facts. (shrink)

In recent years, the project of providing microeconomic foundations for macroeconomics has taken on new urgency. Some philosophers and economists have challenged the project, both for the way economists actually approach microfoundations and for more general anti-reductionist reasons. Reductionists and anti-reductionists alike, however, have taken it to be trivial that the macroeconomic facts are exhaustively determined by microeconomic ones. In this paper, I challenge this supposed triviality. I argue that macroeconomic properties do not even globally supervene on microeconomic ones. This (...) is simply a consequence of the difference in the explanatory goals of the respective fields, which implicitly carve out the microeconomic property set in such a way that it underdetermines macroeconomic properties. It means, however, that microeconomics-based foundations for macroeconomics are inadequate in principle. (shrink)

Popper's well-known demarcation criterion has often been understood to distinguish statements of empirical science according to their logical form. Implicit in this interpretation of Popper's philosophy is the belief that when the universe of discourse of the empirical scientist is infinite, empirical universal sentences are falsifiable but not verifiable, whereas the converse holds for existential sentences. A remarkable elaboration of this belief is to be found in Watkins's early work on the statements he calls “all-and-some,” such as: “For every metal (...) there is a melting point.” All-and-some statements are both universally and existentially quantified in that order. Watkins argued that AS should be regarded as both nonfalsifiable and nonverifiable, for they partake in the logical fate of both universal and existential statements. This claim is subject to the proviso that the bound variables are “uncircumscribed” ; i.e., that the universe of discourse is infinite. (shrink)

The 1994 US spectrum auction is now a paradigmatic case of the successful use of microeconomic theory for policy-making. We use a detailed analysis of it to review standard accounts in philosophy of science of how idealized models are connected to messy reality. We show that in order to understand what made the design of the spectrum auction successful, a new such account is required, and we present it here. Of especial interest is the light this sheds on the issue (...) of progress in economics. In particular, it enables us to get clear on exactly what has been progressing, and on exactly what theory has – and has not – contributed to that. This in turn has important implications for just what it is about economic theory that we should value. (shrink)

After Marx, dissenting economics almost always used 'the labour theory' as a theory of value. This paper develops a modern treatment of the alternative labour theory of property that is essentially the property theoretic application of the juridical principle of responsibility: impute legal responsibility in accordance with who was in fact responsible. To understand descriptively how assets and liabilities are appropriated in normal production, a 'fundamental myth' needs to be cleared away, and then the market mechanism of appropriation can be (...) understood. On the normative side, neoclassical theory represents marginal productivity theory as showing that (a metaphorical version of) the imputation principle is satisfied ('people get what they produce') in competitive enterprises. Since that shows the moral commitment of neoclassical economics to the imputation principle, the labour theory of property is presented here as the actual non-metaphorical application of the imputation principle to property appropriation. The property-theoretic analysis at the firm level shows how the neoclassical (and much heterodox) analysis in terms of 'distributive shares' wholly misframed the basic questions. Finally, the paper shows how the imputation principle (modernised labour theory of property) is systematically violated in the present wage labour system of renting persons. The paper can be seen as taking up the recent challenge posed by Donald Katzner for a dialogue between neoclassical and heterodox microeconomics. (shrink)

This paper challenges Mäki's argument about commonsensibles by offering a case study from contemporary microeconomics – contemporary revealed preference theory (hereafter CRPT) – where terms like "preference," "utility," and to some extent "choice," are radical departures from the common sense meanings of these terms. Although the argument challenges the claim that economics is inhabited solely by commonsensibles, it is not inconsistent with such folk notions being common in economic theory.

Whitehead’s cosmology centers on the self-creation of actual occasions that perish as they come to be, but somehow do combine to constitute societies that are persistent agents and/or patients. “Instance Ontology” developed by D.W. Mertz concerns unification of relata into facts of relatedness by specific intensions. These two conceptual systems are similar in that they both avoid the substance-property distinction: they differ in their understanding of how basic units combine to constitute complex unities. “Process Structural Realism” (PSR) draws from both (...) of these approaches in developing an account of how combinations of processes may produce ontologically significant coherences. When a group of processes achieves such closure that a set of states recurs continually, the effects of that coherence differ from what would occur in the absence of that closure. Such altered effectiveness is an attribute of the system as a whole, and would have consequences. This indicates that the network of processes, as a unit, has ontological significance. The closed network of processes, together with the conditions that prevail, constitute the form of definiteness of the coherence. That form continues to obtain as long as the coherence persists. Constituents contribute to, rather than share, that characteristic. Aspects of some recent research in systems biology, microeconomics, and social psychology illustrate the application of PSR.

The expression "analytic narratives" is used to refer to a range of quite recent studies that lie on the boundaries between history, political science, and economics. These studies purport to explain specific historical events by combining the usual narrative approach of historians with the analytic tools that economists and political scientists draw from formal rational choice theories. Game theory, especially of the extensive form version, is currently prominent among these tools, but there is nothing inevitable about such a technical choice. (...) The chapter explains what analytic narratives are by reviewing the studies of the major book Analytic Narratives (1998), which are concerned with the workings of political institutions broadly speaking, as well as several cases drawn from military and security studies, which form an independent source of the analytic narratives literature. At the same time as it gradually develops a definition of analytic narratives, the chapter investigates how they fulfil one of their main purposes, which is to provide explanations of a better standing than those of traditional history. An important principle that will emerge in the course of the discussion is that narration is called upon not only to provide facts and problems, but also to contribute to the explanation itself. The chapter distinguishes between several expository schemes of analytic narratives according to the way they implement this principle. From all the arguments developed here, it seems clear that the current applications of analytic narratives do not exhaust their potential, and in particular that they deserve the attention of economic historians, if only because they are concerned with microeconomic interactions that are not currently their focus of attention.

Da Gintis ein leitender Ökonom ist und ich einige seiner früheren Bücher mit Interesse gelesen habe, erwartete ich einige weitere Einblicke in das Verhalten. Leider, macht er die toten Hände der Gruppenauswahl und Phänomenologie in die Herzstücke seiner Verhaltenstheorien, und das macht die Arbeit weitgehend ungültig. Schlimmer noch, da er hier ein so schlechtes Urteilsvermögen an den Tag stellt, stellt er all seine bisherigen Arbeiten in Frage. Der Versuch, die Gruppenauswahl seiner Freunde in Harvard, Nowak und Wilson wiederzubeleben, vor ein (...) paar Jahren war einer der größten Skandale in der Biologie in den letzten zehn Jahren, und ich habe die traurige Geschichte in meinem Artikel "Altruismus, Jesus und das Ende der Welt – wie die Templeton Foundation kaufte eine Harvard-Professur und angegriffen Evolution, Rationalität und Zivilisation -- Eine Rezension von E.O. Wilson 'The Social Conquest of Earth' (2012) und Nowak und Highfield 'SuperCooperators' (2012). Im Gegensatz zu Nowak scheint Gintis nicht durch religiösen Fanatismus motiviert zu sein, sondern durch den starken Wunsch, eine Alternative zu den düsteren Realitäten der menschlichen Natur zu schaffen, die durch das (nahezu universelle) Unverständnis der grundlegenden menschlichen Biologie und des leeren Schiefers von Verhaltenswissenschaftlern, anderen Akademikern und der breiten Öffentlichkeit leicht gemacht wird. Gintis greift zu Recht (wie schon oft zuvor) Ökonomen, Soziologen und andere Verhaltensforscher an, weil sie keinen kohärenten Rahmen haben, um Verhalten zu beschreiben. Natürlich ist das Notwendige, um Das Verhalten zu verstehen, evolutionär. Leider bietet er selbst keine selbst (nach seinen vielen Kritikern und ich stimme zu), und der Versuch, die faule Leiche der Gruppenauswahl auf alle wirtschaftlichen und psychologischen Theorien zu transplantieren, die er in seiner jahrzehntelangen Arbeit erzeugt hat, macht nur sein gesamtes Projekt ungültig. Obwohl Gintis sich tapfer bemüht, die Genetik zu verstehen und zu erklären, wie Wilson und Nowak, ist er weit davon entfernt, ein Experte zu sein, und wie sie blendet ihn die Mathematik nur für die biologischen Unmöglichkeiten, und das ist natürlich die Norm in der Wissenschaft. Wie Wittgenstein auf der ersten Seite von Kultur und Wert bekannte: "Es gibt keine religiöse Konfession, in der der Missbrauch metaphysischer Ausdrücke für so viel Sünde verantwortlich war wie in der Mathematik." Es war immer glasklar, dass ein Gen, das Verhalten verursacht, das seine eigene Frequenz verringert, nicht bestehen kann, aber dies ist der Kern des Begriffs der Gruppenauswahl. Darüber hinaus ist bekannt und oft gezeigt, dass Gruppenauswahl nur auf inklusive Fitness reduziert (Verwandtise), die, wie Dawkins festgestellt hat, ist nur ein weiterer Name für evolution durch natürliche Selektion. Wie Wilson arbeitet Gintis seit etwa 50 Jahren in dieser Arena und hat sie immer noch nicht begriffen, aber nach dem Skandal hat es nur 3 Tage gedauert, bis ich die relevanteste professionelle Arbeit gefunden, gelesen und verstanden habe, wie in meinem Artikel beschrieben. Es ist ein Irrsinn zu erkennen, dass Gintis und Wilson nicht in der Lage waren, dies in fast einem halben Jahrhundert zu erreichen. Ich diskusere die Fehler der Gruppenauswahl und Phänomenologie, die in der Wissenschaft die Norm sind, als Sonderfälle des nahezu universellen Versagens, die menschliche Natur zu verstehen, die Amerika und die Welt zerstören. Wer aus der modernen zweisystems-Sichteinen umfassenden, aktuellen Rahmen für menschliches Verhalten wünscht, kann mein Buch "The Logical Structure of Philosophy, Psychology, Mindand Language in Ludwig Wittgenstein and John Searle' 2nd ed (2019) konsultieren. Wer sich für mehr meiner Schriften interessiert, kann 'Talking Monkeys--Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet--Articles and Reviews 2006-2019 3rd ed (2019) und Suicidal Utopian Delusions in the 21st Century 4th ed (2019) sehen.

The beliefs of economists are not solely determined by empirical evidence in direct relation to the theories and models they hold. Economists hold 'ontological presuppositions', fundamental ideas about the nature of being which direct their thinking about economic behaviour. In this volume, leading philosophers and economists examine these hidden presuppositions, searching for a 'world view' of economics. What properties are attributed to human individuals in economic theories, and which are excluded? Does economic man exist? Do markets have an essence? Do (...) macroeconomic aggregates exist? Is the economy a mechanism, the functioning of which is governed by a limited set of distinct causes? What are the methodological implications of different ontological starting points? This collection, which establishes economic ontology as a coordinated field of study, will be of great value to economists and philosophers of social sciences. (shrink)

⦿ In my dissertation I introduce, motivate and take the first steps in the implementation of, the project of naturalising modal metaphysics: the transformation of the field into a chapter of the philosophy of science rather than speculative, autonomous metaphysics. -/- ⦿ In the introduction, I explain the concept of naturalisation that I apply throughout the dissertation, which I argue to be an improvement on Ladyman and Ross' proposal for naturalised metaphysics. I also object to Williamson's proposal that modal metaphysics (...) --- or some view in the area --- is already a quasi-scientific discipline. -/- ⦿ Recently, some philosophers have argued that the notion of metaphysical modality is as ill defined as to be of little theoretical utility. In the second chapter I intend to contribute to such skepticism. First, I observe that each of the proposed marks of the concept, except for factivity, is highly controversial; thus, its logical structure is deeply obscure. With the failure of the "first principles" approach, I examine the paradigmatic intended applications of the concept, and argue that each makes it a device for a very specific and controversial project: a device, therefore, for which a naturalist will find no use for. I conclude that there is no well-defined or theoretically useful notion of objective necessity other than logical or physical necessity, and I suggest that naturalising modal metaphysics can provide more stable methodological foundations. -/- ⦿ In the third chapter I answer a possible objection against the in-principle viability of the project: that the concept of metaphysical modality cannot be understood through the philosophical analysis of any scientific theory, since metaphysical necessity "transcends'' natural necessity, and science only deals with the latter. I argue that the most important arguments for this transcendence thesis fail or face problems that, as of today, remain unsolved. -/- ⦿ Call the idea that science doesn't need modality, "demodalism''. Demodalism is a first step in a naturalistic argument for modal antirealism. In the fourth chapter I examine six versions of demodalism to explain why a family of formalisms, that I call "spaces of possibility'', are (i) used in a quasi-ubiquitous way in mathematised sciences (I provide examples from theoretical computer science to microeconomics), (ii) scientifically interpreted in modal terms, and (iii) used for at least six important tasks: (1) defining laws and theories; (2) defining important concepts from different sciences (I give several examples); (3) making essential classifications; (4) providing different types of explanations; (5) providing the connection between theory and statistics, and (6) understanding the transition between a theory and its successor (as is the case with quantisation). -/- ⦿ In fifth chapter I propose and defend a naturalised modal ontology. This is a realism about modal structure: my realism about constraints. The modal structure of a system are the relationships between its possible states and between its possible states and those of other systems. It is given by the plurality of restrictions to which said system is subject. A constraint is a factor that explains the impossibility of a class of states; I explain this concept further. First, I defend my point of view by rejecting some of its main rivals: constructive empiricism, Humean conventionalism, and wave function realism, as they fail to make sense of quantum chaos. This is because the field requires the notion of objective modal structure, and the mentioned views have trouble explaining the modal facts of quantum dynamics. Then, I argue that constraint realism supersedes these views in the context of Bohm's standard theory and mechanics, and underpins the study of quantum chaos. Finally, I consider and reject two possible problems for my point of view. -/- ⦿ A central concern of modal metaphysicians has been to understand the logical system that best characterises necessity. In the sixth chapter I intend to recover the logical project applied to my naturalistic modal metaphysics. Scientists and philosophers of science accept different degrees of physical necessity, ranging from purely mathematically necessary facts that restrict physical behaviour, to kinetic principles, to particular dynamical constraints. I argue that this motivates a multimodal approach to modal logic, and that the time dependence of dynamics motivates a logic of historical necessity. I propose multimodal propositional (classical) logics for Bohmian mechanics and the Everettian theory of many divergent worlds, and I close with a criticism of Williamson's approach to the logic of state spaces of dynamic systems.

This paper proposes that goods (the things exchanged in financial transactions and an object of study in economics) should be individuated according to a two-place relation constituted by an object and a description. Several of the problems in contemporary philosophy of economics involve shifting focus from objects to descriptions, while certain phenomena central to micro-economics, market regulation, and political economy require consideration of one of the two places. The paper argues thatby considering both constituents in a relation, many of those (...) issues can be more effectively addressed, communicated, and even resolved. The issues that may be so resolved include the seminal discussions of transformable goods, or goods whose existenceor relevant properties are impacted by their means of acquisition (e.g., buying, giving, awarding, etc.). The two-place approachto individuation shows how the cases of transformable goods can be more effectively addressed without incurring problematicmetaphysical commitments which may spiral out into confusion in the ethical and social scientific literature. The paper thenargues that the two-place approach can be leveraged into more fruitful discussion in microeconomics and the ongoing literature inthe metaphysics and ethics of markets. -/- . (shrink)

由于金蒂斯是一位资深经济学家,而且我饶有兴趣地阅读了他的一些以前的书,所以我期待对行为有更多的见解。可悲的是,他把群体选择和现象学的死手变成了他行为理论的核心,这在很大程度上使工作无效。更糟糕的是,由 于他在这里表现出了如此糟糕的判断,这就使他对以前的所有工作都提出了质疑。几年前,他在哈佛、诺瓦克和威尔逊的朋友试图重新选择团体,这是过去十年中生物学领域的重大丑闻之一,我在《利他主义、耶稣和世界末日》 一文中讲述了这个悲惨的故事——邓普顿·福 foundation 买下了哈佛大学教授职位,攻击了进化、理性和文明——对E.O.威尔逊的《地球的社会征服》(2012年)和诺瓦克和高菲尔德"超级合作者"(2012年)的回顾。与诺瓦克不同,金提人似乎并 非出于宗教狂热,而是强烈希望为人性的严峻现实创造一种替代方案,而(几乎普遍)缺乏对人类基本生物学的理解和空白石板主义的使之变得容易。行为科学家、其他学者和一般公众。 Gintis正确地攻击(正如他以前多次)经济学家、社会学家和其他行为科学家没有一个连贯的框架来描述行为。当然,理解行为所需的框架是一个进化的框架。不幸的是,他未能提供一个自己(根据他的许多批评家,我同 意),并试图嫁接腐烂的尸体的群体选择到任何经济和心理理论,他在他的几十年的工作,只是使他的整个项目无效。 虽然金蒂斯勇敢地努力去理解和解释遗传学,比如威尔逊和诺瓦克,但他远非专家,和他们一样,数学只是使他看不到生物学上的不可能性,当然这是科学的常态。正如维特根斯坦在《文化与价值》第一页中著名的指出的那样: "没有宗教派别滥用形而上学的表达方式像在数学中那样造成如此多的辛德。 一直很清楚,导致行为降低其自身频率的基因不能持久,但这是群体选择概念的核心。此外,众所周知,并经常证明,群体选择只是减少到包容性健身(亲属选择),正如道金斯指出,这只是另一个名字进化的自然选择。和威尔 逊一样,金蒂斯在这个舞台上工作了大约50年,但至今还没有掌握,但是丑闻爆发后,我只用了3天时间就找到、阅读和理解了最相关的专业工作,就像我的文章所详述的。想到金蒂斯和威尔逊在近半个世纪里未能实现这一点 ,这令人费解。 我讨论了群体选择和现象学的错误,这是学术界的常态,是几乎普遍不理解正在毁灭美国和世界的人性的特殊情况。 那些希望从现代两个系统的观点来看为人类行为建立一个全面的最新框架的人,可以查阅我的书《路德维希的哲学、心理学、Min d和语言的逻辑结构》维特根斯坦和约翰·西尔的《第二部》(2019年)。那些对我更多的作品感兴趣的人可能会看到《会说话的猴子——一个末日星球上的哲学、心理学、科学、宗教和政治——文章和评论2006-20 19年第3次(2019年)和自杀乌托邦幻想21篇世纪4日 (2019) .

चूंकि Gintis एक वरिष्ठ अर्थशास्त्री है और मैं ब्याज के साथ अपने पिछले पुस्तकों में से कुछ पढ़ा है, मैं व्यवहार में कुछ और अंतर्दृष्टि की उम्मीद कर रहा था. अफसोस की बात है, वह समूह चयन और phenomenology के मृत हाथ व्यवहार के अपने सिद्धांतों के centerpieces में बनाता है, और यह काफी हद तक काम अमान्य. इससे भी बदतर, क्योंकि वह इस तरह के बुरे निर्णय यहाँ से पता चलता है, यह सवाल अपने पिछले काम में कहता है. (...) हार्वर्ड, Nowak और विल्सन, कुछ साल पहले में अपने दोस्तों द्वारा समूह चयन पुनर्जीवित करने का प्रयास पिछले दशक में जीव विज्ञान में प्रमुख घोटालों में से एक था, और मैं अपने लेख 'Altruism, यीशु और दुनिया के अंत में दुखद कहानी सुनाई है कैसे टेम्पलटन फू एक हार्वर्ड प्रोफेसरशिप खरीदा है और विकास, तर्कसंगतता और सभ्यता पर हमला किया - ईओ विल्सन 'पृथ्वी के सामाजिक विजय' (2012) और Nowak और Highfield 'SuperCooperators' (2012) की समीक्षा. Nowak के विपरीत, Gintis धार्मिक कट्टरता से प्रेरित नहीं लगता है, लेकिन मजबूत करने के लिए मानव प्रकृति की गंभीर वास्तविकताओं के लिए एक विकल्प उत्पन्न करने की इच्छा से, बुनियादी मानव जीव विज्ञान और खाली स्लेटिज्म की समझ की कमी (के पास सार्वभौमिक) द्वारा आसान बना दिया व्यवहार वैज्ञानिकों, अन्य शिक्षाविदों, और आम जनता.
