Applications of Small-World Networks to some Socio-economic Systems  [PDF]
A. S. Elgazzar
Physics , 2002, DOI: 10.1016/S0378-4371(02)01956-8
Abstract: Small-world networks (SWN) are found to be closer to the real social systems than both regular and random lattices. Then, a model for the evolution of economic systems is generalized to SWN. The Sznajd model for the two-state opinion formation problem is applied to SWN. Then a simple definition of leaders is included. These models explain some socio-economic aspects.

Abstract: In a broad sense, the term competition” defines the relations between economic operators acting on the same market seeking attainment of certain interests in economic freedom conditions. The need for regulations in the area of competition stems from the nature of free, open market economy which is founded on the existence of fair competition between economic agents, competition which must be observed, maintained and protected by the law. Public authorities who issue various regulations should be cautious about how far this role is played in the economy and they way adopted regulations affect competition in the market. Hence, the need for prior assessment relating to the potential effect of a regulation on competition. It was proven in practice that some regulations may lead to measures that may affect competition directly or indirectly by: limiting the number or range of suppliers; limiting supplier capability to compete and reducing interests of suppliers to compete vigorously.

Abstract: Are economic freedoms going to clear our way to prosperity? Is the growth of economic freedoms our path to prosperity? Is it in the base of the new understanding of development? If yes, what will necessarily have to be changed in the economic practice of every country and whole world in general? What will be changed in economic theory? What are potential consequences of an attempt to offer resistance to the new concept of development? These are just some of the questions discussed in this paper, whereas the starting point is the economy and economic development of Montenegro.
Efficiency of economic development models

Abstract: The world economy is becoming increasingly integrated. Integrating emerging economies of Asia, such as China and India increase competition on the world stage, putting pressure on the "actors" already existing. These developments have raised questions about the effectiveness of European development model, which focuses on a high level of equity, insurance and social protection. According to analysts, the world today faces three models of economic development with significant weight in the world: the European, American and Asian. This study will focus on analyzing European development model, and a brief comparison with the United States. In addition, this study aims to highlight the relationship between efficiency and social equity that occurs in each submodel in part of the European model, given that social and economic performance in the EU are not homogeneous. To achieve this, it is necessary to analyze different indicators related to social equity and efficiency respectively, to observe the performance of each submodel individually. The article analyzes data to determine submodel performance according to social equity and economic efficiency.
Some of the unanswered questions in finance  [PDF]

Panoeconomicus , 2006, DOI: 10.2298/pan0602223d
Abstract: A very dynamic development of finance in the last 50 years is inter alia probably due to experiments and innovations in this field. Previously theoretical base could not explain and predict movements especially in volatile times. "The new finance" appeared 50 years ago (portfolio theory CAPM, the efficient market theory, M&M theorem) and made substantial progress in understanding movements in globalized and internationalized financial markets. However, many questions remain open. The author tries to put emphasis on some of these questions, perfectly aware that these are not the only ones. Unresolved questions are related to company's aims, project's risks, degree of portfolio optimization, importance of liquidity, dividend policy, as well as factors that determine M&A. As the "new finance" is not able to predict and explain volatile movements, a question that should be posed is whether it is appropriate to add some non-economic factors as the behaviorist theory suggests. Although the behaviorist theory is an important part of "new finance", it is unfortunately the only theory able to explain movements in volatile times. In conclusion, many questions still remain unanswered and wait for appropriate theoretical explanations.
Asia-Pacific and European Economic Competitiveness: An Analysis of Economic-Power-Shift from the West to the Emerging Giants

Journal of Economics Theory , 2012,
Abstract: The global economic meltdown has marked a new dawn in the economic interplay between the West and countries in the Asia pacific region. This study is a regional economic excursion at identifying the nature of economic-institutional-changes that pave a way for economic power shift from the West to the Asian region. The study analyses some of the key areas of economic advancement, indices and dynamics of economic recession. Findings show that the Western economies are facing a great economic hardship on one hand, while on the other hand, the economies of the Asia pacific especially the emerging giants are becoming more prosperous and rapidly growing. The study concludes that with the global economic debacle, few years to come, the economies of the Asian emerging giants will outstrip the economies of the west and become the world leading economies. The study recommends a fair competition that would open a way for the development of the third world among other things.

Abstract: From establishing the European Coal and Steel and so far, European economic integration has seen remarkable success. There are however a number of difficult issues unresolved. Will EU succeed to move forward towards a political union and to shape a foreign policy that would enable a major role in international relations? The new confrontation that is taking place at the international level is not based on political-military conflict anymore, but rather on economic and technological competition to get a bigger part in the global economy. But will the acquisition of a world economic power status will allow them to remove American hegemony?

Abstract: In the present stage of development of international economic relations multilateral regulation of competition is becoming more and more important in order to, firstly, annul the effects of domestic rules of competition that are today considered the greatest non-tariff limitation, secondly avoid conflicts that can be caused by exterritorial implementation of national rules in this field, and, finally, define the rules of behavior in the world market. Although the first attempts to regulate this field were made pretty long ago and some activities were taken within UNCTAD, OECD and GATT, no comprehensive rules considering the issues they define and a group of countries that implement them have been adopted at the international level, so far. For the time being, numerous competition problems in relations among countries have been overcome by concluding a number of bilateral agreements and several regional arrangements.
Competition Policy under Economic Recessions: Historical Changes and Implications  [PDF]

Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.43A026

Before the current financial crisis, economic recessions in history were always accompanied by relaxation or abandon of competition policy. However, in the current financial crisis, although different jurisdictions have different practices, most jurisdictions have kept the bottom line of competition policy enforcement. Such historical transformation roots in deep reflections on historical failures and the popularization of competition policy as well as the strengthening of the competition authorities. Chinais one of the few countries still weakening competition policy enforcement during the current financial crisis. In fact, there are several mechanisms contained in competition laws and policies, such as the exemption of cartels, the defense of business concentrations and the coordination between competition authorities and sector regulators, which provide some space of flexible competition policy enforcement during economic recessions. Considering China’s short history of competition policy enforcement and consistent tradition of government intervention in economy, it is strongly advised to hold on the bottom line of competition policy and pay more attention to government-led anti-competitive conducts during economic recessions.

Competition ability dependence on uniqueness in some collaboration-competition bipartite networks  [PDF]

Abstract: Recently, our group quantitatively defined two quantities, "competition ability" and "uniqueness" (Chin. Phys. Lett. 26 (2009) 058901) for a kind of cooperation-competition bipartite networks, where "producers" produce some "products" and "output" them to a "market" to make competition. Factories, universities or restaurants can serve as the examples. In the letter we presented an analytical conclusion that the competition ability was linearly dependent on the uniqueness in the trivial cases, where both the "input quality" and "competition gain" obey normal distributions. The competition between Chinese regional universities was taken as examples. In this article we discuss the abnormal cases where competition gains show the distributions near to power laws. In addition, we extend the study onto all the cooperation-competition bipartite networks and therefore redefine the competition ability. The empirical investigation of the competition ability dependence on the uniqueness in 15 real world collaboration-competition systems is presented, 14 of which belong to the general nontrivial cases. We find that the dependence generally follows the so-called "shifted power law (SPL)", but very near to power laws. The empirically obtained heterogeneity indexes of the distributions of competition ability and uniqueness are also presented. These empirical investigations will be used as a supplementary of a future paper, which will present the comparison and further discussions about the competition ability dependence on the uniqueness in the abnormal collaboration-competition systems and the relationship between the dependence and the competition ability and uniqueness heterogeneity.
