The model of social network is used to analyze the impact of the power of labor unions in the labor relations. We find that labor union capable to affect a pecuniary compensation of shirking employees lessens the motivation of employees to work and improve to the unionization rate. As a result,...

Paper analyzes the impact of incentives and disincentives on the decision-making of individuals. Their role in the decision-making processes is huge, as they affect the cost-benefit analysis of investment projects of scarce resources. They both are subject of huge negative effects. A hidden trap...

In (Istrate et al. SODA 2001) we advocated the investigation of robustness of results in the theory of learning in games under adversarial scheduling models. We provide evidence that such an analysis is feasible and can lead to nontrivial results by investigating, in an adversarial scheduling...

We study the evolution of imitation behaviour in a differentiated market where firms are located equidistantly on a Salop circle. Firms choose price and quantity simultaneously, leaving open the possibility for non-market clearing outcomes. The strategy of the most successful firm is imitated....

The neoclassical theory of the firm deals with the pattern of perfect competition, within which the perfect information available to economic agents provides instant allocation of production factors and access to economic goods. The Austrian School (C. Menger, L. von Mises, Hayek, etc.)...

There is growing evidence that face-to-face interaction is declining in many countries, exacerbating the phenomenon of social isolation. On the other hand, social interaction through online networking sites is steeply rising. To analyze these societal dynamics, we have built an evolutionary game...

In the paper, I simulate the games with a joint presence of 95% VaR-rule and return-rule groups of agents. Simulations highlighted the level of omniscience, next being the rule, which agents follow at the decision-making, and the third the presence of liquidity agents in the game. Omniscient...

This paper analyzes the field of investors’ decision-making on a multi-asset market. It does it through a simulation games on a social network framework. It has been demonstrated that more stocks there are in the game and more changing alternatives investors have available to choose from,...

We model the formation of friendships as repeated cooperation within a set of heterogeneous players. The model builds around three of the most important facts about friendship: friends help each other, there is reciprocity in the relationship and people usually have few friends. In our results...

In the paper, I simulate the social network games of a portfolio selection where agents consider VaR when managing their portfolios. Such agents behave quite differently from the agents considering only the expected returns of the alternatives that are available to them in time. The level of...
