Opis:: In this paper the design stages of a mixed photovoltaic-wind energy system, supplied with solar and wind energy was discussed. First, general information about the employed wind turbines and solar panels is given and their basic characteristics are addressed. Then, essential information for the system setup and measurements was given. The system setup, operation of the system, the ways to store energy and how energy is consumed were described and the results were interpreted. This study serves as a background for the experimental studies in the future.

Opis:: In this study we compared incomes distributions in the USA for two subgroups (defined according to sex or race). We utilized the quantile decomposition method to describe differences between the two distributions as a function of their quantiles. The analyzed objects are characterized by the set of attributes (education, age, etc.). We evaluate strength of the influence of the attributes onto the various parts of the incomes distributions. In such a way we evaluate income inequalities and their causes in two subgroups of people.

Tytuł:: Microeconomic Evolution Model with Technology Diffusion
Autorzy:: Cichy, K.

Opis:: The model discussed in this paper is a modification of the model of macroeconomic evolution in stable regionally dependent fields, developed by Ausloos, Clippe and Pekalski in 2004. Like in the original model, firms exist on a square lattice and can move, merge, adapt and create spin-offs. However, in the new model the firms are described by a scalar parameter identified with their level of technology and by their market share. The probability of survival of a firm depends on the relation between the firm's technology level and the level of the technological frontier. The model incorporates two mechanisms of technology diffusion - inner (resulting from the cooperation between firms and the creation of spin-offs) and outer (interaction with the technological frontier). In this way, we obtain a model of technological progress with technology diffusion. We investigate the properties of this model and perform empirical analysis for a group of OECD countries.

Opis:: The aim of our research is to propose a method of rating companies which is based on efficiency measure given by Data Envelopment Analysis (DEA). Proper rating of borrowers is an essential requirement of PD estimation. The difficulty in DEA application is the selection of input and output from the set of indicators describing evaluated objects, which is usually based on expert knowledge. Therefore we apply random forests and gradient boosting to select financial indicators used by the DEA approach and to obtain a ranking of companies needed for PD estimation.

Opis:: In this paper we study the relations between personal incomes and incomes of families with two adults in USA. We describe family income distributions using the simple two-parametric model. Assuming incomes of spouses are statistically independent of each other we obtain theoretical exponential income distributions for males and females. We show that these distributions are not coincident with distributions constructed based on the personal data. Obtained results indicate on statistical dependence between incomes of males and females in the families. We track changes and trends in data for years from 2001 to 2016.

Opis:: This paper is concerned with two coupled Kaldor-Kalecki models of business cycles with delays in both the gross product and the capital stock. We consider two types of investment functions that lead to different behavior of the system. We introduce the model with unidirectional coupling to investigate the influence of a global economy (like the European Union) on a local economy (like Poland). We present detailed results of numerical analysis.
