Assuming human rationality in decision-making: An understanding of the normative bedrock of [standard] economics

“Even if utilities look very unnumerical today, the history of the experience of the theory of heat may repeat itself, as it happened, though in different forms and ways, for the theory of light, colours, and radio waves.” [von Neumann and Morgenstern, 1944, p. 17].

The year 2024 marks eighty years since the publication of von Neumann and Morgenstern’s [1944] seminal work “Theory of Games and Economic Behavior”. Since its inception in 1944, this work has been highly influential not only for being the boldest and methodical attempt to address the subject upon which modern game theory is based, but also for representing the first systematic application of formalised game theory to the social sciences. In the work, among other things, the two authors introduce the concept of stable sets and separate cooperative games from non-cooperative ones. Nevertheless, when faced with the problem of solving variable-sum games, they adopt the line that the solution space of such games effectively reduces to a negotiated solution and thus can be solved as coalition games via the concept of stable sets. The discussion is supplemented by mathematics underpinned by selfish-maximising rationality and complete information assumptions, which align with the 'economistic' paradigm and the related axiomatisation of formal systems.

This brings us to the nub of the matter: By analysing games played by perfectly rational and fully informed decision-makers, especially in the fields of economic relations and social organisation, von Neumann and Morgenstern’s [1944] seminal work also suggests the possibility of applying game theory on a large scale to address problems inherent to economic strategies and—increasingly and more soundly—to the framework of organisational, social, political, military, and environmental issues. Hence the idea of including this mathematical theory in various research projects and degree course syllabi gives rise to fruitful contamination between ideas belonging not only to different disciplines but even to three disciplinary fields, such as the formal sciences, the social and cognitive sciences.

Therefore, in addition to being relevant to contemporary game theory, the diverse nature [and complexity] of that seminal work is generally understood to go well beyond the mathematics of rational decision-making by interacting individuals. Aside from providing a much deeper theoretical understanding of expected utility theory, this understanding expands the academic scope beyond that of mathematicians and encompasses multiple fields of inquiry, making it a more comprehensive body of knowledge. From this perspective, it is appropriate to look back on von Neumann and Morgenstern’s [1944] work and reflect critically and insightfully on what it meant, particularly its implications for the social and cognitive sciences, how it developed, and where we are today, recalling two of its key points here: The adoption of individual decisions as the starting point of economic research and the underlying [or rather overlying] role of human rationality in framing decision processes.

There appears to be wide recognition that, building on that work, advanced research in economics—and related areas—began to involve decision analysis, which soon shifted from parametric studies to strategic analysis. With the former, roughly speaking, the economic agent takes prices as given when making decisions, without any concern for the price-determining behaviour of other agents; with the latter, the agent takes into account the predictable reactions of others to her choices. This being the case, the assumptions and beliefs that shape the concept of rationality underlying economic behaviour allow the field of possible decisions to be narrowed down while constituting the strengths and weaknesses of the related theoretical framework. Yes, it is widely known that the book by von Neumann and Morgenstern [1944] is presented based upon an axiomatic structure comprised of postulates articulating the standard economic model of rational choice in decision-making, considering the preferences of each individual for any possible event, and assuming that the probabilities of the events are given. Once the axioms have been formulated—the main one being the postulate of rationality, understood as the lack of contradictions—the cornerstone of standard economic theory can be traced back to a set of logically necessary relations of mere deductive procedures that would characterise human behaviour.

Interestingly enough, the two authors’ seminal work, to which this Call refers, also allows their view of utility as an objectively measurable natural phenomenon to emerge. The work also assumes that a single probability measure is defined for all events while preferring the frequentist theory of probability to the subjective one. This view seems to align with the pre-Paretian marginalist methodological approach to such an extent that “[e]ven if utilities look very unnumerical today, the history of the experience of the theory of heat may repeat itself, as it happened, though in different forms and ways, for the theory of light, colours and radio waves.” [von Neumann and Morgenstern, 1944, p. 17, brackets added]. In any case, the two authors argue that probability and preference can be axiomatised together, focusing thereby on probabilistic risk instead of dealing with uncertainty. Savage [1954], afterwards, while synthesising the ideas of Ramsey [1931], de Finetti [1930, 1931, 1937] and von Neumann and Morgenstern [1944], introduces a novel analytical framework and conditions that are necessary and sufficient for the existence and joint uniqueness of utility and probability, and the characterisation of individual choice as expected utility-maximising behaviour [i.e., a subjective approach to probability in a model of expected utilities à la von Neumann and Morgenstern, 1944].

All in all, unlike the earlier marginalist tradition, von Neumann and Morgenstern’s unprecedented approach to decision-making concerns game theory and expected utility. This approach broadens the traditional economic focus on the problem of choice when dealing with scarce resources since each choice can lead to multiple outcomes, each with different probabilities. When making a decision, indeed, an economic [neoclassical] agent can calculate the expected utility of each available option by weighing the utility of each possible outcome by its probability. To analyse the expected utility, therefore, the two authors introduce a system of postulates that, in essence, correspond to the completeness, continuity, and transitivity of both preferences and the probabilities attributed to various choices. Furthermore, each preference relationship is considered independent from all other events; in other words, external effects are neglected. Thus, both utility and probability are considered measurable, that is, enumerable. The overarching set of axioms ensures that probability and utility—hence, expected utility—reflect the properties of mathematical expectations. Consequently, by assuming that economic agents have complete information, one can specify their choices [i.e., the system’s solutions] corresponding to rational behaviours or, better, to behaviours that [globally] maximise their expected utility.

Upon closer inspection, von Neumann and Morgenstern’s analysis contains a controversial aspect related to the concept of rationality, which can be understood in a descriptive and normative manner. The paradoxes raised by Allais [1953] and Ellsberg [1961], as well as other authors, make us question the descriptive validity of this concept. However, it could be argued that even its normative framework may also increase scepticism and give rise to criticism. In this wake, Savage’s Foundations of Statistics [1954] represents a significant contribution that builds on and advances the work of von Neumann and Morgenstern [1944]. The Foundations are widely regarded as the basis of modern inferential statistics and determine a crucial shift in the conceptual underpinnings of expected utility theory. Much debate surrounds the so-called "sure-thing principle" axiom, which Savage used for his theory. According to this axiom, the choice between two options [i.e., alternatives] should not be affected by features that have the same value in both options. The Ellsberg [1961] paradox challenges this axiom by contradicting it. This contradiction has paved the way for a more comprehensive theory, providing valuable insights into the diverse aspects of probability, in which the probability measure need not be additive.

Because of the axiomatic focus on rationality, economic agents are allowed to derive the ordinal utility functions from their order of preferences. This way of proceeding has been dominating the marginalist approach to economic studies since Pareto’s works [1897, 1906, and 1911]. Rational behaviour is then assumed as the agent’s choice between alternative options. This choice maximises a specific objective function or, echoing von Neumann and Morgenstern [1944], the value of her expected utility. This would be true even if we claimed or aspired to broaden the field of economics to include the most diverse social phenomena [as advocated by Becker and Nashat, 1997], from micro to macro scales, real-world issues affecting everyday life: As posited by von Neumann and Morgenstern’s formal analysis, humans would be constantly faced with maximisation constraints characterised by a single-dimensional utility function which determines preferences for their actions. Yet still, numerous doubts and controversies have arisen from various research streams—and continue to arise—regarding this conceptualisation of rational [self-referential] behaviour and the standard generalisation that flows into the construction of the homo œconomicus. Among these streams, experimental and computational methodologies stand out, both conducted through various operational methods, deductively and inductively. Also noteworthy is the interdisciplinary research on the border between economics and neurobiology adopting the rejection of the postulate of perfect rationality as a point of departure. It might remain relatively open to attribute a normative significance to the standard theory supported by a sort of Olympian rationality [Simon, 1983] to be equipped with, against which agents’ actual behaviour might be viewed as a divergence from it, even if systematic and inherent to human nature.

It is important to note that upon closer examination of these research streams, it can be suggested that the paradoxes do not necessarily demonstrate the irrational nature of human behaviour. Rather, they reveal that economic agents operate within a more complex context and evolutionary pattern than those assumed by expected utility theory, particularly in two critical aspects. Firstly, agents work under conditions of uncertainty, which is not of a probabilistic kind but of Keynesian-type uncertainty. Precisely, this type of uncertainty corresponds to a limited knowledge of the situation at hand. Keynes believed that when it is possible to give a more or less precise evaluation of expected probability, it should be integrated with another element, the degree of confidence we can have in our probability estimate. This research line is characterised by bounded rationality and satisficing behaviour, as proposed by Simon [1947, 1955, 1959]. Secondly, agents are not driven by a single motivation but by an intricate set of beliefs, passions, and interests, as the Enlightenment tradition emphasises. These motivations may be contradictory, vary over time, and are socially conditioned by social norms and relations. This contrasts with the solipsism adopted by the marginalist tradition, which is consistent with its methodological individualism and the subsequent [neoclassical] hypotheses to which it gave rise.

The argument that economic agents’ behaviour does not comply with the precepts of such rationality, as represented in the expected utility paradigm, sets the groundwork for interdisciplinary research, especially between economics, constructive mathematics, and cognitive sciences, focused on the distinctive characteristics of human behaviour and the logic of discovery (Simon, 1973; Langley et al., 1987; Velupillai, 2005). Both classical and modern behavioural economics give rise to this kind of interdisciplinary work by identifying, among other things, stylised facts that characterise research into judgment, choices, and human decisions while using them to build interpretative models of constructive and computable analysis.

The controversies following the 1944 book by von Neumann and Morgenstern mainly revolve around the conceptualisation of the rationality assumption that underlies the axioms of expected utility theory: rationality understood with a descriptive rather than normative emphasis. Arguably, these controversies are sharper in the study of human decision-making than in any other field of inquiry. Not surprisingly, in all their variations and formulations, utility theories, notoriously, along with the [unrealistic] assumptions to which they give rise in standard economics modelling, presuppose that humans are concerned with both stocks and flows of knowledge systematically, a well-organised and stable structure of preferences, and an excellent ability to compute utility values for all possible paths of action that are available to them. Although a certain academic belief regarding research methodology maintains that scientific disciplines do not have the purpose of explaining the functioning of the real world, the same authors—von Neumann and Morgenstern and similarly also Savage—considered their axioms to be both an abstract but realistic explanation of human economic behaviour and a standard for the adoption of rational decisions. Arrow [1951] also supports this idea [for an accurate reconstruction of these controversies, see Heukelom, 2014]. As with other research milestones, the work "Theory of Games and Economic Behavior" continues today to arouse keen interest but also a healthy scepticism, raising numerous doubts and questions, which makes the 'game' of academic discourse much more enjoyable, allowing research to progress and embrace greater representativeness and greater reliability of the results. Therefore, the eightieth anniversary of that work represents an opportunity to reassess its significance to economics, mathematics, statistics, philosophy, finance, ethics, cognitive sciences, and other fields. In addition, it presents an opportunity to evaluate what remains of it over eight decades of intellectual development.

The above and some broader questions and issues about the intellectual forces operating in the development of scientific thought will be examined in the course of the Conference together with the founding topics of DECON. This year, too, the challenge is undoubtedly both theoretical and paradigmatic but also rigorously methodological, empirically, and experimentally grounded. It applies to all aspects of the interdisciplinary methodological approach that stems from the work of von Neumann and Morgenstern [1944]. This approach concerns several fields of science, starting with mathematics, statistics, economics, and social structures while spilling over into other research fields. Papers in the 2024 edition of Decision Economics are encouraged to support more interdisciplinary work accordingly.

SPECIAL CONFERENCE TRACKS
________________________________________________________________________________________


In addition to the main conference track, six special sessions are also planned to enable insights into economics, decision-making, cognitive sciences, and related subjects. They will represent further highlights of the sixth edition of Decision Economics by connecting a dynamic and interdisciplinary group of researchers to the Conference:

(i) “AI-driven Decision Making” (AIDM) is an immersive session organised and coordinated by Stefano Za and Marco Smacchia (University of Chieti-Pescara, Italy), and Michele Cipriano (Catholic University of the Sacred Heart - Piacenza). One of the interests of this special track is related to the design and evaluation of AI-driven decision making. At the same time, this track also raises the question of whether and how relatively more rational and mindful decision-making could depend on human-driven and AI-driven policy influence.

(ii) “Ethics of Decision-Making and Economics” (EDME) is a consolidated session organised and coordinated by Tony E. Persico (Georgia Institute of Technology, Atlanta), Tony Guidotti (Harvard University), and Elizabeth Garlow (New America Foundation). The session aims to discuss and understand today’s ethical challenges in political economy and economic policy, focusing on economic methodology and the philosophy of science and economics.

(iii) “Smart Heuristics for Civil Servants” (SMAHCS), launched by Rino Rumiati (University of Padua) and Davide Pietroni (University of Chieti-Pescara), is a thought-provoking session that explores various topics related to effectively engaging with the complexity and uncertainty inherent in the issues the civil service and public administration institutions face.

(iv) “Economics, Law and Psychology in Taxation: Perspectives and Critical Issues of Behavioral Taxation” (BETA) by Salvatore Villani and Loredana Strianese (University of Naples Federico II) is a novel conference session aimed at disseminating recent advancements and emerging trends in the psychological analysis of economic behaviour pioneered by scholars such as George Katona.

(v) “Socio-Behavioural Research and Human-Centred Design” (SOCBER) by Ionut Virgil Serban (University of Craiova) and Gianmarco Cifaldi (University of Chieti-Pescara) is a novel conference session intended to highlight behavioural science on decision-making and design research, understanding the stakeholders’ perspectives to help policies and programmes respond properly to human evolving needs.

(vi) “Decision-Making for Public Sector Recovery” (DEPSER) by Simone Cifolelli and Lorenzo Fabiani (University of Chieti-Pescara) is a novel session that aims to broaden perspectives and inspire action to reaffirm the strategic role of the State, regulation, local government, and public finance in the economy of uncertainty.




KEYNOTE LECTURES

AWARDS, SOCIAL COMMITMENT, AND PUBLICATION OPPORTUNITIES
________________________________________________________________________________________


Finally, catered towards the relevant scientific and scholarly community, this year, too, the permanent Scientific Committee of DECON will award the best paper prize and the best paper application prize—together with the prizes awarded by the MDPI international publishing house. In this regard, particular attention will be paid to those manuscripts involving one or more research efforts, such as the methodological rigour and soundness of research, theoretical relevance, analytical accuracy and potential field contamination, including the quality of the study design, implementation, analysis as well as strength of evidence, with the appropriate differentiations between the two main sections of the prize. The prizes are awarded to anyone participating in one of the DECON 2024 special sessions, including the main track. As in earlier years, this year too DECON facilitates cross-fertilisation between theories, methodologies, and applications of decision-making and mathematical foundations of economics. All accepted papers will be included in a peer-reviewed special book indexed by Scopus or in a digital library with an ISSN/ISBN code. The decision on whether a paper is included in the book or library will depend on the relevance of the paper as assessed by the reviewers. Each author who submits a paper must adhere to the required scientific rigour and provide timely feedback to the reviewers, the Managing Editor in charge and, where necessary, the Steering and Organising Committee. Failure to collaborate and provide the necessary feedback will result in exclusion from any publication.

Additionally, the founders of DECON have proposed a special issue on “Axioms, best possible decisions, and other normative parables: Addressing personal and situational dynamics to grasp what causes rationality to be ecological while making decisions” to the Editorial Board of ‘New Mathematics and Natural Computation’, a peer-reviewed international scientific journal founded in 2005, now in its twentieth year of operation, and published by World Scientific. Further instructions will be communicated in due course. Should one or more modifications become necessary, DECON’s Steering and Organising Committee reserves the opportunity to modify the content of this Call at its discretion and without notice, in accordance with the highest international academic standards.
