Purpose: The problem of identifying the most important determinants of the market value of football players is quite well described in the literature. There are many works that try to identify these factors. Some of them are focused on variables to make a set complete and others are on models and methods. The aim of this article is to present the variables influencing the valuation and to build an econometric model valuing footballers playing on the forward position, taking into consideration the assumptions of the econometric modelling. Such an approach indicates managers as other sources for obtaining information. Methodology: Econometric models were used to verify the hypothesis formulated in this research. The database was created on the basis of variables presented on the website www.transfermarkt. de that presents the values of the most valuable football players in the world playing on the forward position. The Gretl program was used in the research. Findings: The literature review showed that there are many independent variables having an impact on the value of the player. There are also many different models used to valuate footballers’ performance rights. The results of estimation of models in the research indicated that such factors as Canadian classification points adjusted the market value of the team and dummy variables describing “goodwill” (only for the best players) had an impact on the market value of footballers’ performance rights. Limitations/implications: Information about different factors having an impact on football players’ market value could support the investment decision process of football managers. Originality/value: The results were part of a study concerning economics of sport, particularly processes of management of football clubs and valuation of intangible assets.

The paper demonstrates the problem and range of quantitative subjects (statistics and econometrics) on Faculty of Economic Sciences, University of Life Sciences in Warsaw. The introduction presents Microsoft Excel, a commercial spreadsheet application, which gained a positive opinion of the students who felt that, in addition to econometrics, they even learnt to use the tool used not only in econometrics or statistics. The introduction of the new law on higher education, which is to abolish the teaching standards, may result in reducing the hours of statistics, econometrics, mathematics and others.

The business environment dynamics is governed by a high degree of uncertainty and risk; consequently, in a majority of cases investors face serious difficulties when making business decisions. Additionally, when detailed statistical information relating to industry is missing, any decisions may become a matter of highly risky conjectures. The present article proposes a simultaneous equation model based on the entropy econometrics estimator for recovering some key industrial subsector long-term equilibrium characteristics in the situation where only sparse, insufficient statistical information is available (e.g. only aggregated data on the whole industry). The model is applied to the transportation equipment manufacturing industry in Poland, which is composed of eight sub-sectors. As a result of the above procedure, an observation has been made that all firms from different sub-sectors have to increase their steady-state concentration ratios, while the highest concentration corresponds to the lowest increase in profitability. The model outputs conform to the market tendency in this sector and should lead to further applications of the NCEE methodology in business activity on a worldwide scale.

The purpose of the article was to point out the possibilities of applying metaanalysis in economic science and particularly in econometrics. So far, in Poland meta-analyses were applied in behavioral sciences, medicine and some in economic studies and management, whereas this method has been used used elsewhere since the 1970s for solving a wide spectrum of problems in many fields of study. The present article shows meta-analysis as the method using statistical tools the most, from amongst all the methods of the literature review, and it shows the procedure of carrying it out step by step and its advantages and disadvantages.

Econometric models have produced contradictory results and have failed to provide warning of housing market crashes. The article aims to illustrate how econometrics was unable to reliably predict the recent housing price bubble and detect the disequilibrium in the housing markets. The authors will demonstrate that two distinct but well specified econometric models, using the same data, can lead to different outcomes. The authors argue that the demand for housing is influenced by social constructs, social norms, ideologies, unrealistic expectations, symbolic patterns, and that the actual choice of housing is the outcome of complex social interactions with reference groups. Consequently, it is necessary to analyse the potential instability of social constructs, norms, expectations and the changing character of social interactions to better understand purchasing behaviour and, then, housing price volatility.

The formal description of economic phenomena requires the application of mathematical notions and mathematical techniques. When making formal description of economic phenomena we have to formulate all accepted assumptions in an open way. This prevents us from all errors and misunderstandings that can be created while formulating conclusions, results and forecasts. In this paper we present the advantages resulting from the application of formal description of economic phenomena. We also discuss approaches to the mathematical model link and we present some observations about the teaching of mathematics on economic studies.

The article is about Russian regional airports, air mobility of people in regions of Russia, geographical distribution and results of econometric forecasting of these figures based on demographic and economic factors. Also some historical reviews, a description of the current situation and international comparisons are provided. The research revealed that people’s income and investment (both current and accumulated) are the main factors affecting air transportation growth in the studied airports. In the long-term perspective air traffic of Russian airports can triple by 2030, while Russian air mobility figures can exceed the present ones in Western Europe.

Proces badawczy zawarty w niniejszym tekście odnosi się do kwestii powiązań procesów politycznych z procesami ekonomicznymi. Korelacja została wykryta na poziomie międzynarodowym w przypadku polityki i ekonomii Stanów Zjednoczonych. Procesem politycznym jest polityka zagraniczna USA rozumiana w kategoriach militarnych, a procesem ekonomicznym jest makroekonomia gospodarki USA. Zjawiska polityczne oraz zjawiska ekonomiczne zostały przedstawione jako cykle, a następnie przebadane zostały pod względem korelacji: w pierwszej kolejności intuicyjnie i percepcyjnie, a następnie ekonometrycznie.
EN
The research described in the paper explores the links between political and economic processes. The correlation was detected at the international level in the politics and economics of the United States. U.S. foreign policy viewed in terms of the military constitutes the political process, while the economic process is the macroeconomic situation in the U.S. economy. Political events and economic phenomena are presented in the shape of cycles, which are then examined in terms of correlations: first intuitively and perceptually, then econometrically.

The author explores the notion of knowledge-based economy and, using one definition as her point of departure, undertakes an attempt to provide an econometric proof showing that some countries actually are moving towards a knowledge-based economy. The author also identifies factors employed by countries in the process. Such countries meet essential criteria of macroeconomic stability and, above all, ensure satisfactory quality of public institutions (in the realm of economy and politics). Enabling factors for a knowledge- based economy include high quality of human capital (provided that conditions are in place to make a productive use of this capital) and high quality of information systems.
PL
Autorka dokonuje identyfikacji terminu „gospodarka oparta na wiedzy”. Na podstawie przyjętej definicji podejmuje próbę przeprowadzenia ekonometrycznego dowodu na to, że niektóre kraje realnie zmierzają do gospodarki opartej na wiedzy, a także wskazuje, jakie czynniki wykorzystują w tym procesie. Kraje te spełniają niezbędne warunki w zakresie stabilizacji makroekonomicznej, a przede wszystkim zapewniają odpowiednią jakość instytucji publicznych (w sferze gospodarki i polityki). Do czynników umożliwiających rozpoczęcie budowy gospodarki opartej na wiedzy należą wysoki poziom kapitału ludzkiego - jeśli wcześniej zostały stworzone warunki do jego produktywnego wykorzystania - oraz wysoki poziom systemu informatycznego.

Prowadzenie działalności gospodarczej oznacza permanentne ścieranie się z różnorodnymi ro-dzajami ryzyka gospodarczego, rozumianymi jako wystąpienie zdarzenia niepożądanego, które ma negatywny wpływ na zakładane przez przedsiębiorcę efektywności gospodarcze. Powstają więc pytania: czy ryzykiem można zarządzać tak, aby minimalizować skutki wystąpienia niepo-żądanych zdarzeń i co należy rozumieć przez zarządzanie, a także jakimi narzędziami należy się posługiwać. Na te pytania Autor stara się odpowiedzieć w niniejszym artykule lub też zasygnali-zować konieczność doprecyzowania określonych zakresów merytorycznych. Zarządzanie ryzykiem antymonopolowym jest oczywiście możliwe, lecz warunkiem zwiększającym efektywność tego procesu jest ustalenie jak najściślejszych zasad oceny antymonopolowej lub też – krok dalej – kwantyfikacja takiej oceny. Dysponując określonymi algorytmami oceny antymono-polowej lub też skwantyfikowaną ich postacią (formalna postać może być zapisana jako funkcja), można tak zaprojektować działalność przedsiębiorstwa, aby pozwoliła na minimalizowanie ryzyka uznania określonych praktyk biznesowych za działania niezgodne z prawem antymonopolowym. W konsekwencji zminimalizowane zostałoby także ryzyko nałożenia na przedsiębiorcę (lub na osoby zarządzające) stosownych kar. Przygotowanie takiego mechanizmu analitycznego jest moż-liwe jedynie w warunkach skonkretyzowania przez Urząd Ochrony Konkurencji i Konsumentów wytycznych, na podstawie których możliwe byłoby prowadzenie analiz zgodności projektowanych zamierzeń biznesowych z prawem antymonopolowym i wprowadzanie stosownych modyfikacji.

Conducting an economic activity means the permanent clash of diverse economic risks, understood as the appearance of the undesirable event of a negative impact on economic efficiency expected by the entrepreneur. Some questions have to be addressed at this point: (1) is it possible to manage the risk in order to minimize the consequences of undesirable events; (2) how the decrees should be understood and; (3) what instruments should be used? An attempt is made in this paper to answer these questions, or to indicate the need to clarify or to define their substantial scopes. Managing antitrust risk is of course possible – what is required in order to increase the efficiency of this process is to establish correct analytical mechanisms (precise principles of antitrust estimation), or even take one step further – to quantify such an evaluation. Specific algorithms of antitrust estimation, as well as their quantified figure (the formal figure could also be recorded as a function), make it possible to design a business activity so as to minimize the risk of that practice being categorized as an antitrust infringement and consequently, to minimize the risk of a fine being imposed on the entrepreneur (or on its manager). However, such analytical mechanisms could only be devised if the Polish NCA provided guidelines that could act as the basis for an antitrust compliance analysis of business strategies and plans and their appropriate modifications.

Artykuł omawia obecne zastosowania metod ekonometrycznych w analizach szarej strefy. Przedstawione zostały ramy formalne metodologii badania gospodarki nieoficjalnej oraz możliwości metod ekonometrycznych w analizach kierunkowanych zarówno na szacowanie rozmiarów szarej strefy, jak i na pogłębione badania jej struktury oraz związków przyczynowo-skutkowych. Poza metodami pośrednimi, jak bilans zużycia energii elektrycznej M. Lackó czy analiza popytu na pieniądz V. Tanziego, szeroko omówiona została metodologia modeli równań strukturalnych, oceniona jako podejście z niewykorzystanym potencjałem eksplikacyjnym.

The article presents the current applications of econometric methods in the analysis of gray economy. The work presents a formal framework of methodology for the study of unofficial economy and the possibilities of econometric methods in analyzes aimed at estimating the size of the shadow economy and in-depth studies of its structure and cause-and-effect relationships. In addition to indirect methods, such as the balance of electricity consumption (household electricity approach) of M. Lackó or the analysis of the currency demand method of V. Tanzi – the methodology of structural equation models, assessed as an approach with unused exploratory potential, has been widely discussed.
