Social network analysis is one of the fields in the social sciences which went through a huge development in the last two decades. With the availability of newer tools and methods, in-depth analysis of huge networks became possible resulting in important results at various fields. Despite this...

In this paper, we focus on the economic research of corruption. In the first part, we define corruption, types of corruption, its factors and ways to measure it. This section brings together various definitions by notable authors of this domain, such as Begovic, Tanzi, Mauro or Lambsdorff....

A voting situation is given by a set of voters and the rules of legislation that determine minimal requirements for a group of voters to pass a motion. A priori measures of voting power, such as the Shapley-Shubik index and the Banzhaf value, show the influence of the individual players. We used...

An Small and Medium Enterprise (SME) is able to cope with the global challenge if it realizes reliable, balanced and high-standard operation in its business. There are some management and organizational methods increasing the competitiveness of SME. Controlling as a management tool and...

While they use the language of game theory the known measures of a priory voting power are hardly more than statistical expectations assuming the random behaviour of the players. Focusing on normalised indices we show that rational players would behave dierently from the indices' predictions and...

In this article, we generalize the position value, defined by Meessen (1988) for the class of deterministic communication situations, to the class of generalized probabilistic communication situations (G´omez et al. (2008)). We provide two characterizations of this new allocation rule....

We survey axiomatic results concerning the Shapley value (Shapley (1953)). This marginalist allocation rule results from an axiomatic study of the class of coalitional games. Shapley (1953) specifies a list of desirable properties of solutions for this class of games, and he shows that the...

In Hungary there exist two big and well- known scholar information systems (SIS). Both of them have become part of everyday life in the adminis - tration of higher education. These SISes have made quite a long journey dur - ing their evolution. Even so, they have some annoying disadvantages even...

An electrical transmission network consists of producers, consumers and the power lines connecting them. We build an ideal (lossless) DC load ow model as a cooperative game over a graph with the producers and consumers located at the nodes, each described by a maximum supply or desired demand...
