A clarification of the Goodwin model of the growth cycle

We show that there is a difficulty in the original Goodwin model which isalso found in some more recent applications. In it both the labour share and theproportion employed can exceed unity, properties which are untenable. However, weshow that the underlying dynamic structure of the model can be reformulated toensure that these variables cannot exceed unity. An illustrative example extends theoriginal model, and we argue it is both plausible and satisfies the necessary unit boxrestrictions.

Strategic management of intellectual capital of the enterprise in the framework of informatization of the economy

In the course of the research, one has determined the scientific and theoretical approaches, related to the identification of the directions and tools needed to improve strategic management; one also provided the main directions of the intellectual capital formation and development within the enterprise, which include the state of the capital at the present stage and the requirements to it from the future knowledge economy: the introduction of human capital into the assets of the enterprise, the promotion of the creative activity of the employees of the enterprise by using factors of human and social capital activation, as well as the establishment of an accounting system and evaluation of intangible assets. We have highlighted a range of specific principles of the intellectual capital management at the enterprise: the establishment of a partnership between all participants of the production process within the enterprise, namely, its owners, managers, and employees; the determination of criteria for assessing the contribution of every employee into the final result of the enterprise activity; the arrangement of an integrated network of the workers’ mass participation to identify the potential reserves, improve the production efficiency, and the product quality; the development of measures upon the principles’ implementation; and the primary task orientation of management on the future competition. One formulated the scientific and methodological foundations regarding the development of measures, aimed to improve the management of the intellectual capital of an enterprise, which include a sequence, the procedure of determination, the justification, the evaluation of the appropriateness of particular measures, the involvement of a wide range of workers in their development via the methods of interrogation and questionin

Wittgenstein's Thought Experiments and Relativity Theory

In this paper, I discuss the similarity between Wittgenstein’s use of thought experiments and Relativity Theory. I begin with introducing Wittgenstein’s idea of “thought experiments” and a tentative classification of different kinds of thought experiments in Wittgenstein’s work. Then, after presenting a short recap of some remarks on the analogy between Wittgenstein’s point of view and Einstein’s, I suggest three analogies between the status of Wittgenstein’s mental experiments and Relativity theory: the topics of time dilation, the search for invariants, and the role of measuring tools in Special Relativity. This last point will help to better define Wittgenstein’s idea of description as the core of his philosophical enterprise
