In this paper the general principles and categories of mixed economy that currently exist in almost all countries of the world are presented. The paper also presents an Advanced Model of Mixed Economy with Threshold (AMMET), which is characterized by a reduced value (approx. 10-15%) of the State and public sector participation in the national economy and proposes and analyzes an econophysics model for the mixed economy.
Knowing and modelling the migration phenomena and especially the social and economic consequences have a theoretical and practical importance, being related to their consequences for development, economic progress (or as appropriate, regression), environmental influences etc. One of the causes of migration, especially of the interregional and why not intercontinental, is that resources are unevenly distributed, and from the human perspective there are differences in culture, education, mentality, collective aspirations etc. This study proposes a new econophysics model for the migration phenomena.
The green area of economy is the key of healthy living. It is necessary to convene economic and ecologic framework to establish a market attentive to drastic reduction of emissions damaging our climate and landscapes in rural areas, to the protection of biological diversity of the planet, to stop producing nuclear waste, etc. This paper tries to demonstrate human concern for a waste recycling economy that will provide new jobs, will create economic and social stability and will ensure a healthier and cleaner environment. Green Economy and its support system (planetary ecosystem) won't be in conflict anymore. Green Economy will be able to support economic progress for future.
This article presents a theoretical model for a dynamic system based on sustainable development. Due to the relatively absence of theoretical studies and practical issues in the area of sustainable development, Romania aspires to the principles of sustainable development. Based on the concept as a process in which economic, social, political and natural environment are combined in order to sustain planet management, our goal is to promote an economic tool for Romanian decision-makers in order to evaluate scenarios and planning options.
In this paper are made some considerations of the application of phenomenological thermodynamics in risk analysis for the transaction on financial markets, using the concept of economic entropy and the macrostate parameter introduced by us in a previous works [15,16]. The investment risk diagrams for a number of Romanian listed companies in 2008 and 2009 years were calculed. Also, the evolution of the macrostate parameter during financial and economic crisis in Romania are studied.
In this paper will be applied some principles and methods from econophysics in the case of the direct foreign investitions (D.F.I.), particularised for the Greenfield type, and mixed firms of trade and industrial production (Joint Ventures). To this aim will be used some similarities and parallelisms between the mentioned economic domains and some phenomena and processes from physics, especially from thermodynamics, solid state physics (the grow of crystals and thin policrystalline layers etc.), electromagnetism etc.
In this paper we present an econophysic model for the description of shares transactions in a capital market. For introducing the fundamentals of this model we used an analogy between the electrical field produced by a system of charges and the overall of economic and financial information of the shares transactions from the stock-markets. An energetic approach of the rate variation for the shares traded on the financial markets was proposed and studied.
After September 2008, the advanced economies severe decline caused demand for emerging economies' exports to drop and the crisis became truly global, much deeper and broader than expected. In these times of global depression, most countries and companies are affected, some more than others. The financial crisis has turned out to be much deeper and broader than expected. Entering new markets has always been a hazardous entrepreneurial attempt, but also a rewarding one, in the case of success. The paper aims to asses the market entry risk of a company trying to make a good acquisition, to buy shares of another company, activating in a foreign country. For this purpose, the case of Electroputere S.A., the old Romanian producer of railway equipment, has been chosen. The data were collected from the records of Bucharest Stock Exchange. After two years from the acquisition, one can draw a conclusion whether the strategy of the investor was a good one or a waste of money.
After the shocking series of bankruptcies started in 2008, the public does not trust anymore the classical methods of assessing business risks. The global economic severe downturn caused demand for both developed and emerging economies' exports to drop and the crisis became truly global. However, this current crisis offers opportunities for those companies able to play well their cards. Entering new markets has always been a hazardous entrepreneurial attempt, but also a rewarding one, in the case of success. The paper presents a new indicator meant for assessing the prospective of success or failure for a company trying to enter a new market by using an associative strategy. In order to take the right decision concerning the optimal market entry strategy, marketers may use a software application, "AnBilant", created by a research team from Hyperion University.
In this paper we attempt to introduce an econophysics approach to evaluate some aspects of the risks in financial markets. For this purpose, the thermodynamical methods and statistical physics results about entropy and equilibrium states in the physical systems are used. Some considerations on economic value and financial information are made. Finally, on this basis, a new index for the financial risk estimation of the stock-exchange market transactions, named macrostate parameter, was introduced and discussed. Keywords: econophysics, stock-exchange markets, financial risk, informational fascicle, entropy, macrostate parameter.
Most of the econometric and econophysics models have been borrowed from the statistical physics, and as a cosequence, a new interdisciplinary science called econophysics has emerged. In this paper we planned to extend the analogy between different economic processes or phenomena and processes and phenomena from different fields of physics, other than statistical physics. On the basis of the economic development process and amplification phenomenon analogy, a new econophysics model, named economic amplifier, on the electronic amplification principle from applied physics was proposed und largely analyzed.
