The problem of measurement in economic models and the possibility of their quantum-mechanical description are considered. It is revealed that the apparent paradox of such a description is associated with a priori requirement of conformity of the model to all the alternatives of free choice of the observer. The measurement of the state of a trader on a stock exchange is formally defined as his responses to the proposals of sale at a fixed price. It is shown that an analogue (...) of Bell's inequalities for this measurement model is violated at the most general assumptions related to the strategy of the trader and requires a quantummechanical description of the dynamics of his condition. In the framework of the theory of weak continuous quantum measurements, the equation of stock price dynamics and the quantum-mechanical generalization of the F. Black and M. Scholes model for pricing options are obtained. The fundamental distinctions between the obtained model and the classical one are discussed. (shrink)

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. We were also able to obtain the classical interpretation of the quantum-mechanical law of addition of probabilities by introducing a number of new notions. The principle of “local equity” assumes the transaction completed (regardless (...) of the result) of the states of transaction partners are not changed in connection with the reception of new information on proposed offers or adopted decisions (consent or refusal of the transaction). However it has no relation to the paradoxes of quantum theory connected with non-local interaction of entangled states. In the economic systems the mechanism of entangling has a classical interpretation, while the quantum-mechanical formalism of the description of states appears as a result of idealization of the selection mechanism in the proprietor's consciousness.

The paper discusses the possibility of constructing economic models using the methodology of model construction in classical mechanics. At the same time, unlike the "econophysical" approach, the properties of economic models are derived without involvement of any equivalent physical properties, but with account of the types of symmetry existing in the economic system. It has been shown that at this approach practically all known mechanical variables have their "economic twins". The variational principle is formulated on the basis of formal mathematical (...) construction without involving the subjective factor common to the majority of models in economics. The dynamics of interaction of two companies has been studies in details, on the basis of which we can proceed to modeling of more complex and realistic economic systems. Prediction of the possibility of constructing economic theory on the basis of primary principles analogously to physics has been made. (shrink)

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. Elementary (indivisible) technology, in which the object's consumer values are variable, in this case can be formalized as a generalized economic measurement. The algebra of such measurements has been constructed. It has been shown (...) that in the general case the quantummechanical formalism of the theory of selective measurements is required for description of such conditions. The economic analogs of the elementary slit experiments in physics have been created. The proposed approach can be also used for consciousness modeling. (shrink)

We analyze the properties of optimum portfolios, the price of which is considered a new quantum variable and derive a quantum analog of the Black-Scholes formula for the price of financial variables in assumption that the market dynamics can by considered as its continuous weak measurement at no-arbitrage condition.

The approach to the study the role of strategic alliances in the conditions of digital business transformations has been further developed in the article. In the course of a critical analysis of the content of scientific publications of modern scientists who studied the behavior, peculiarities of activity and the meaning of strategic alliances, it was established that the role of strategic alliances in the conditions of digital transformations does not disappear, but brings new advantages, requiring the maximization of returns from (...) more dynamic partnership relations, which requires more in-depth study of such benefits. Dynamics analysis of the number of concluded agreements in the field of strategic partnership in the period of 2014-2023 demonstrates their increase starting from 2017, which led to the activation of digital business transformations. In the course of research, it was determined that the role of strategic alliances in the conditions of digital business transformations is to ensure strategic flexibility under the conditions of continuity of digital transformations, improve competitive positions on the market, increase their innovativeness and efficiency, improve organizational stability and the ability of companies to learn, create opportunities for obtaining synergistic effect. It develops the ability of companies to proactively manage changes, contributes to the joint solution of strategic tasks and goals of partner companies, provides significantly greater opportunities for the development of innovative processes through the development and implementation of new methods and forms of work, new solutions in economic sectors, innovations in management, contributes to survival in market competitive environment and is an important competitive imperative to ensure overall long-term digital transformation.

Battin et al examined data on deaths from physician-assisted suicide in Oregon and on PAS and voluntary euthanasia in The Netherlands. This paper reviews the methodology used in their examination and questions the conclusions drawn from it—namely, that there is for the most part ‘no evidence of heightened risk’ to vulnerable people from the legalisation of PAS or VE. This critique focuses on the evidence about PAS in Oregon. It suggests that vulnerability to PAS cannot be categorised simply by reference (...) to race, gender or other socioeconomic status and that the impetus to seek PAS derives from factors, including emotional state, reactions to loss, personality type and situation and possibly to PAS contagion, all factors that apply across the social spectrum. It also argues, on the basis of official reports from the Oregon Health Department on the working of the Oregon Death with Dignity Act since 2008, that, contrary to the conclusions drawn by Battin et al, the highest resort to PAS in Oregon is among the elderly and, on the basis of research published since Battin et al reported, that there is reason to believe that some terminally ill patients in Oregon are taking their own lives with lethal drugs supplied by doctors despite having had depression at the time when they were assessed and cleared for PAS.

R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

These original essays explore the philosophical implications of Newton's work.

The Stoics maintained that virtue was the only good; everything else, therefore, was not-good. On the other hand, regarded by itself, this huge class was not equally valueless. Vice, of course, was bad; but everything else was thought to be ‘indifferent’: wealth, health, for example; indifferent, that is, with regard to the summum bonum. Of these Intermediates, men, from human nature, had a leaning to some; these were , had value, were called , that is, preferred, and virtue itself lay (...) in choice exercised among them. (shrink)

For almost the whole of the first half of the nineteenth century, philosophy at Moscow University was subjected to fierce persecution at the hands of the authorities. Their aim was, evidently, to smother in the cradle any manifestation of freethinking among students, the thinking part of Russian society. It was no coincidence that philosophy was chosen as the target of persecution, because the study of this science could lead by the shortest path to reflections concerning man's place in the world, (...) the role of the social sciences, the just or unjust nature of the existing state order in Russia, and so on. What would a student who got carried away by, for instance, Socrates's ideal of inner freedom or Spinoza's pantheistic system become? For a classical police state, which imperial Russia was, that was intolerable. One need merely recall that Chaadaev, Herzen, and many other rebels had at some time studied at the university. Russia's rulers clearly had no need of such people. (shrink)

Posidonius was a major intellectual figure of the Hellenistic world whose interests and contribution spread over the whole intellectual field: philosophy, history, the sciences. His writings are of interest not only to philosophers and classicists, but also to historians and history of science. His work survives only in fragments. The text of these fragments, collected and edited by L. Edelstein and I. G. Kidd, was published in 1972, with a second edition in 1989. This collection, along with Vol. II The (...) Commentary by I.G. Kidd, has become established as the definitive modern edition. However, many of the fragments are extremely difficult to translate, and this volume of translations has been compiled to make this interesting material more easily accessible to scholars and students. The translations are accompanied by contextual introductions and explanatory notes where necessary. An Introduction summarises the importance of Posidonius and his work. (shrink)
