This book provides a comprehensive overview of the fundamental concepts and principles of microeconomics. It introduces students to the models, assumptions, and empirical applications of modern microeconomics, as well as to the necessary mathematical tools. It covers topics such as economic behavior, consumer theory, theory of the firm, partial and general equilibrium theory, industrial organization, bargaining theory, and Pareto optimality. Students learn not only about economic outcomes at a given point of equilibrium, but also about dynamic economics, which includes both equilibrium and disequilibrium. This book is intended for undergraduate and graduate students in economics and related fields who are interested in the basic theories and applications of microeconomics

An original neo-Schumpeterian endogenous model of economic growth is presented in the article. The model includes the capital market and is an expansion of the Aghion-Howitt model [2009]. In the model, the rate of economic growth is equal to the rate of growth of the average level of technology, which is a direct consequence of innovation, the authors say. The following sets of agents are identified in an economy described with this model: the final production sector, the intermediate production sector, the R&D sector, the government sector, and the capital market. On this basis, the dynamics of the economy was described. The theoretical discussion was expanded to include empirical research, in which the key parameters of the model were calibrated. Additionally, a Monte Carlo simulation of the economy's dynamics was performed. On the basis of the research, the authors concluded that the main determinant of economic growth is the process of generating innovations by enterprises, which directly influences the level of technology used in production. The capital market has a significant impact on the dynamics of processes occurring in the real economy, the authors note. Technological competition helps achieve the desired state of the economy. The authorities support technological competition because it promotes the growth of the frontier level of technology and spurs economic growth. Enterprises strive to maximize their expected profits from their core business, which encourages them to improve their production technology and outperform the competition. The expectations of companies about future economic trends play an important role in shaping the dynamics of the whole system. The key issue is how risk aversion influences the portfolio investment process, the real economic decisions of enterprises and consequently economic growth, the authors note.

The text is devoted to new trends and changes emerging in the economic sciences, focused on growth, socio-economic development and income inequalities in the context of the idea of global rationality, understood as the ability to sustain the long-term existence of civilization on the entire planet. The thematic scope of this problem is broad; thus it is impossible to cover all its complexity in one study. Hence, attention is focused on selected aspects of the issues raised: on issues related to growth and development as well as economic inequalities, the economic foundations of growth, and the issue of substituting natural capital by human capital. A critical diagnosis and postulates for the future, with regard to measures of well-being in the context of the idea of sustainable development, are also considered as well as including the issue of sustainable development in development economics. The article ends with concluding remarks highlighting the thesis that economic growth should now be acceptable only when it does not excessively exploit natural capital and does contribute to deteriorating the quality of life. As for the methodological side of the text, it was created mainly through analysing the literature on the subject, but attention should be paid to the original nature of some predictions and recommendations, which were made as a result of the assumptions of the so-called diagnostic and prognostic analysis.
