Opis:
The concept of mass poverty was defined by Galbraith in late 1970s and it applies to societies with agriculture as the dominant branch of the economy. This paper examines the importance of this phenomenon and factors affecting it in the contemporary world. There are a growing number of studies supporting the claim that the method of electricity consumption is a key factor of economic growth which makes it possible to escape mass poverty. Moreover, in order to solve the problem, it is necessary to determine access to capital in such countries and societies, understood as M2 aggregate. In this manner, the problem at hand is reduced to determination of the relationships between the following variables: percentage of rural population, rules of managing electrical energy and M2 aggregate. These findings were used to formulate three study hypotheses. According to the first hypothesis, the effect of the electricity use method on M2 varies from one country to another, with several identifiable patterns. According to the second hypothesis, the process of leaving the mass poverty sphere follows either the Bose-Einstein distribution or the Boltzmann distribution. The third hypothesis indicates that effects of efforts aimed at eliminating mass poverty in certain conditions are not permanent. Verification of these three hypotheses indicates the adequacy of the theory of mass poverty in the contemporary world.

Opis:
This article presents a network algorithm for identifying transactions which may constitute a violation of restricted periods, namely, making transactions in company shares by persons possessing inside information. The empirical research was performed on the basis of publicly available information on exchange trading, originating from the Warsaw Stock Exchange. The analysis is based on a numerical model which describes information spreading in a network with an information bottleneck. The applied method can confirm with high probability the use of inside information for carrying out unauthorized stock market transactions.

Opis:
The insider trading phenomenon is based on the situation when traders use material information not publicly available to make their investment decisions. In most countries of the world, insider trading is illegal and is punishable by fine or imprisonment. Insider trading has many economic effects, which in the light of available scientific research can be both positive and negative. Insider traders can be divided into primary and secondary traders depending on whether their contact with insider information is direct or indirect. Primary insider trading has been discussed in many research studies and scientific descriptions, while secondary insider trading has not been investigated yet. This paper's aim is to fill this gap. Since the empirical data for secondary insider trading is in practice impossible to obtain, the research analysis is based on simulations of two probabilistic models. The first one concerns the use of insider information for an infinite long period of time after its acquisition, while the second one on the day of its receipt. The results of the simulation are related to three basic models of financial market functioning: the efficient market hypothesis, the fractal market hypothesis, and the coherent market hypothesis.
