    Opis:
    The discourse about commodification of time indicates that under the current socio-economic regime important values get systematically ignored. This paper reviews literature about the value of time in classical political economy, neoclassical economics, the household production approach, household economics, and activity models. Starting with neoclassical economics, all these approaches are largely in accordance with utilitarian methodology. Utilitarian methodology turns out to be incapable of explaining the value of time. The debate about “quality work” allows us to identify the following intrinsic values: power, playfulness, a sense of meaning, and a sense of belonging. These intrinsic values match with the “five sources of motivation” in contemporary psychological research, which confirms the empirical relevance and irreducibility of these values for understanding behaviour. We propose a definition of commodification of time and illustrate some of the potential effects of commodification of time.

    Opis:
    Utility is a fundamental notion of orthodox (mostly neoclassical) economics, but as it is an idea, that is very vague and thus impossible to define and measure, it did a lot of harm to economics as a science. Therefore, I strongly argue that this outdated and imprecise concept should be finally abandoned, especially as a basis for microeconomic consumer theory, because it is not only illogical, but also ideologically not neutral, and thus unscientific. For sheer inertia, the concept of utility, as a basis for microeconomic theory, is taught to the students, thus corrupting the young minds. Furthermore, the present financial and economic crisis, the most serious since the 1930s, should force the economists from the academia to seriously revise the foundations of microeconomic theory, and, as logical consequence, rewrite the handbooks in microeconomics. I do not merely argue that the utility theory defies both logic and empirical justification, as many authors did it before me. I argue that the very notion of utility is unscientific, and was kept in microeconomic books only because of sheer inertia, but this way it made a lot of harm to the science of economics, and, as a result to the real economies. I also argue that the subjectivist theory of value should be replaced with an objectivist one, based on value of labour.

    Opis:
    Aim: This article was written out of a felt need to reflect on the relationship between economic theories and models on the one hand and the empirical world as we experience it on the other. The question is in particular whether it is possible for economic models and theories to say anything definitive about the world we live in.   Design/Research methods: The article relies on professional publications, both within the field of economics and outside of it.   Conclusions/findings: There is much reason for humility, economic models and theories have hardly anything definitive to say about the empirical world, and there is a need for a more varied menu of theories and models and for a listening ear for the needs and fears of the population at large. The best we can do is discussing competing and conflicting views in a polite way. However, this requires a Sprachethik that looks more and more like an endangered species.   Originality/value of the article: Recent developments concerning the reach of economic models and theories are related to earlier discussions and a way forward is sketched

    Opis:
    Ewa Domańska, a distinguished historian of historiography and the methodologist of history, has provided an insightful commentary on the state of humanities and social sciences. The development of interdisciplinary research in social sciences and humanities has resulted in varying outcomes and interpenetrations. Interdisciplinary research helps the development of science. However, studies undertaken with less rigor may pose some threats into the long term. According to Domańska, the lack of qualifications and care (especially with respect to theory and methodology) may undermine the autonomy of a disciplines and the credibility of research in the given field. This timely warning prompted the author to create the project with the aim to assert the independence of the threatened disciplines and to “re-professionalize” these areas of study. This is to be achieved by emphasizing the role of theory in science-a strong embeddedness of a discipline in the theory. Domańska’s concept, in the form of a dichotomous project, seems to be a recipe for achieving this goal. It presupposes, on the one hand, a “practical methodology”, i.e. constructing the theory basing on empirical research material, and on the other hand the so-called “virtue epistemology”, which stresses an ethical aspect of the researcher’s attitude and labour. The aim of the paper is to discuss Domańska’s project and to draw attention to the originality of her concept in the context of economic and social sciences. The economic history is a peculiar discipline founded at the intersection of history and economics. Thus, it is possible to put forward the thesis that Domańska’s suggestions are relevant to the research of economic history. The author will seek to determine what cognitive opportunities arise from the ontology of economic history and their potential threats to the main disciplines of history and economics. The article will also examine if Domańska’s project is appropriate for the economic history research as it is deeply embedded in “practical methodology”, and so in theory. Next, the author aims to consider the role of new theoretical approaches in this field, and whether it is possible to formulate novel concepts within the scope of the economic history. Finally, the author will attempt to assess the significance of “virtue epistemology” or the ethical aspect of an economic historian’s work.

    “That in the age of numbers, numbers only can be turned to for supporting one’s propositions” – once more on the Polish studies of economic history (Summary)The authors, in referring to the paper written by Rafał Matera and published in this issue, argue that good studies from the field of economic history should 1) offer analyses informed by a social and economic theory; 2) make use of comparative methods, including as an advisable option the quantification of a series of data; 3) create or rely on specialized databases. Through the analysis of a number of works, the authors show that present-day Polish economic historians often fail to meet the requirements outlined above, thus making Polish historiography lag increasingly behind the historiography of other countries.

    Opis:
    The article is devoted to the phenomenon of economic inertia. The authors of the study conducted sufficiently detailed research of economic inertia, on the basis of which the damage to the economy from various economic reforms or economic shocks can be revealed in a timely manner. as Additionally, guidelines can be outlined for further economic growth and sustainable economic development. In their in-depth research on the concept of economic inertia, the authors introduced into usage and employed new concepts of certainty, uncertainty, insufficiency and the redundancy of economic inertia. The authors delineated out as many as four levels of complexity of economic inertia uncertainty. The empirical research is based on a model of the impact of subsidies on the economy. The research model demonstrates that the use of subsidies decreases the market equi-librium price. Innovative companies lose motivation to pursue sustainable economic growth and ensure competitiveness. In this case, the phenomenon of economic inertia is obvious and deprives businesses of the incentives to use innovation to ensure eco-nomic growth. Thus, subsidies as a system of stimulus and rescue in the strategic as-pect of increasing competitiveness have negative effects on the country's economy.

    Opis:
    The global recession and the sovereign debt of European countries has triggered an intense debate over the effectiveness of fiscal policy and over the consequences of rising public debt. The purpose of this paper is to determine if there exist a correlation between the public debt and the economic growth in Albania, where the economic growth will be considered as the increase of GDP. The results and the methodologies are different in different countries and periods, as represented by various empirical studies. What is the situation in Albania at about the last 25 years? The SVAR methodology is used for analyzing this relationship. The results indicated that an instantaneous increase in real economic growth might increase the public debt and vice versa.

    Opis:
    Research background: This study presents the results of the research which aimed to identify and critically discuss existing methodologies in the merger and acquisition field. Value creation to merging and acquiring firms and national countries constitute the center of the research. This study distinguishes between specific methodologies employed to gauge M&A performance on a micro- (corporate) and macro- (economy and society) economic levels. The final section of the paper concludes with a theoretical methodological framework integrating methodologies employed to measure M&A performance on a firm level and methodologies measuring consequences and effects of M&A on the economy. The aim of the analysis described in the paper is to ascertain and evaluate theoretically existing methodologies used in empirical studies that would allow proper and critical understanding of the results of various findings in the holistic and global M&A area. Purpose of the article: The purpose of the paper is to investigate and critically discuss the methodologies employed within the M&A performance framework with the focus on specific anticipated outcomes of the M&A deal and methodology measuring this outcome. The following objectives are being raised: (1) To identify recent developments in the M&A market and determine challenges and changes they encompass. (2) To identify and critically discuss anticipated outcomes of the M&A deal and existing methodologies measuring M&A performance on the corporate level; (3) To identify and critically discuss anticipated outcomes of the M&A deal on the economy and methodologies measuring consequences and effects of M&As on the macro- economic level; (4) To integrate methodologies measuring M&As performance on a micro- and macro- economic levels into theoretical methodological framework enabling scholars and practitioners to evaluate M&A performance from a holistic perspective. Methods: Based on previous studies, the authors conduct a structured literature review aimed to critically discuss and evaluate developments and challenges of measuring M&A performance on corporate and macroeconomic levels. The research is carried out as a structured assessment of past literature. The findings from scientific articles and studies by various scholars are being categorized, grouped and summarized to discern a meta‐analytic view of the work carried out to date. Finally, deep analysis of scientific literature, logical comparative analysis, systematization of scientific article and business cases are employed in the article. Findings & Value added: The paper evidences developments and challenges of measuring M&A performance on corporate and macroeconomic levels. The re-search elaborates on several key developments in M&A methodology and performance studies carried out in empirical works during the last two decades. The findings help to independently and objectively assess performance of M&A from a holistic perspective.

    Objectives: To seek for the optimum economic model for public utility services in the sector of municipal waste management; to present the results of studies regarding the efficiency of companies in the sector of management of municipal waste and the systems that such companies function within. Research Design & Methods: Multi-criterion rankings with the use of synthetic variable, the structure of which has been based on zeroed unitarisation (method of zeroed unitarisation – MZU). Owing to general financial data, technical and operational data, as well as output data, it was possible to determine rankings of effectiveness for companies in the system of municipal waste management and communes. What is more, a correlation diagram was created – the dependency between the aggregated effectiveness of companies and the aggregated effectiveness of waste management in communes. Findings: Communes which entrust municipal companies with management of an integrated system for municipal waste management or/and its individual chains feature more properties of operating, economic, and financial effectiveness within the scope of management of municipal waste. Implications / Recommendations: It is demonstrated that communes which entrust municipal companies with management of an integrated system for municipal waste management – or/and its individual chains – feature more properties of operating, economic, and financial effectiveness within the scope of the management of municipal waste. Contribution / Value Added: Further extended research into the organisation and management of the municipal waste management system. Article classification: The article presents an original and innovative analysis of the municipal waste management sector with the use of the developed research method of aggregation and unit efficiency ranking. The purpose is to continue the extended research on the organisation and management of the municipal waste management system.

    Opis:
    A theory for a phenomenon needs to explain its main empirical features. In the case of modern economic growth, these include the times and places where it has occurred, its magnitude, the distinction between cutting-edge and catch-up growth, and the uniformity of the growth process despite major cultural and institutional heterogeneity. I summarise the historical record to characterise the explanandum, then review the main theoretical perspectives. I find that most leading theories fail to explain the main observed features of modern economic growth. In particular, the magnitude of growth and other key characteristics suggest the need for a systems analysis. An implication is that the economy is driven by interacting economic forces, rather than being merely reactive to external non-economic influences such as preferences and technology.

    Opis:
    Based on the fact that the concept of expectation is marginalized in economic sociology, where action and communication theories dominate, this paper reflects on the potential of expectations or, more precisely, expected expectations. In pursuing this objective the author works out the characteristics of expected expectations as the foundation of social structure in general and market structure in particular, with a special focus on social change. Considering the assumption that expectations shape action and communication on the one hand, and given theoretical compatibility on the other, there is, therefore, every indication that an appropriate expectation theory should be elaborated – with the exception of Popitz’s objection. Heinrich Popitz argues against highlighting expectations in theory because of the methodological problem that one cannot prove whether one specific expectation leads to a specific behaviour. The author counterposes two arguments against Popitz’s position: First, expected expectations are made observable, hence they can be expected. Whilst we are focusing on second-order expectations there is no methodological issue. And secondly, the clou of this paper is that expected expectations finally reveal their social power on the basis of an ‘as-if’ logic: actors can legitimately be treated as if they orientate themselves towards expected expectations, e.g. on the basis of formal or informal rules, and this guarantees (temporary) stability.
    Odwołując się do faktu, iż pojęcie oczekiwania jest marginalizowane w socjologii ekonomicznej (zdominowanej przez teorie działania i komunikacji), autor tekstu rozważa potencjał tego pojęcia, a dokładniej pojęcia oczekiwanych oczekiwań. Autor przedstawia charakterystykę oczekiwanych oczekiwań jako – w sensie ogólnym – podstawy struktury społecznej, a w szczególności struktury rynku, koncentrując przy tym swoją uwagę na zmianie społecznej. Zakładając, że oczekiwania z jednej strony kształtują działania i proces komunikacji, z drugiej zaś podążając za wymogiem teoretycznej zgodności, wykazać zatem można potrzebę wypracowania stosownej teorii oczekiwań – z wyłączeniem zastrzeżenia Popitza. Heinrich Popitz sprzeciwia się bowiem podnoszeniu teoretycznego znaczenia oczekiwań z powodu problemu metodologicznego – według tego autora nie jest możliwe udowodnienie, że określone oczekiwanie prowadzi do takiego, a nie innego działania. Autor tekstu formułuje dwa kontrargumenty wobec zastrzeżenia Popitza: po pierwsze, oczekiwane oczekiwania stają się obserwowalne, zatem mogą być oczekiwane. Kwestia metodologiczna znika więc, jeśli koncentrujemy się na oczekiwaniach drugiego rzędu. Po drugie, sednem tekstu jest twierdzenie, iż oczekiwane oczekiwania ujawniają swoją społeczną moc na podstawie logiki „tak, jakby”: aktorów społecznych można w sposób uprawniony rozpatrywać tak, jakby orientowali się oni według oczekiwanych oczekiwań, na przykład na podstawie reguł formalnych lub nieformalnych, co zapewnia (tymczasową) stabilizację działań.

    Opis:
    Artykuł poświęcony jest znalezieniu odpowiedzi na następujące pytanie: czy koncepcja nowego pragmatyzmu autorstwa prof. G.W. Kołodko jest alternatywą czy uzupełnieniem ogólnej teorii ekonomicznej? Autor uważa, że pozytywny potencjał nowego pragmatyzmu polega na jego praktycznej przydatności do analizy w oparciu o interdyscyplinarne podstawy konkretnych sytuacji, rozwijających się zarówno w różnych gospodarkach narodowych, jak i w gospodarce światowej. Koncepcja ta nie powinna być traktowana jako alternatywa dla ogólnej teorii ekonomicznej. Jest to raczej rodzaj mostu nad „obszarem niepewności”, który istnieje między abstrakcyjną teorią ekonomiczną a rzeczywistością ekonomiczną.
    The article is devoted to finding the answer to the following question: is the concept of the new pragmatism developed by Professor G.W. Kołodko an alternative or a supplement to the general economic theory? The author’s position is that the positive potential of the new pragmatism consists in its practical usefulness for the analysis of specific situations developing both in various national economies, as well as in the global economy, based on the interdisciplinary grounds. This concept should not be considered as an alternative to the general economic theory. Rather, it is a kind of a bridge over the “area of uncertainty”, which necessarily exists between an abstract economic theory and the economic reality.

    Opis:
    After long history of mining of Zn-Pb ore deposits their resources are considerably exhausted. The 'Olkusz-Pomorzany' is the only active mine. Further mining is possible of undeveloped deposits in Olkusz and Zawiercie areas. They were explored since 1970-1990 with the use of vertical boreholes. The borehole density was the basic criteria for estimation of resources assessment accuracy. Resources were calculated with the use of polygonal (Boldyriew) method. The deposit parameters defined in particular boreholes were assigned individually to the whole surrounding polygons. This method was undisputable in the case of most rich startoidal ore bodies (ore zones). Undeveloped deposits are composed of several local, net like ore bodies horizontally and vertically dispersed. For assessment of their resources a new approach was proposed based on limited extrapolation of borehole data up to the distance corresponding to the autocorrelation radii of zinc content. It was evaluated by geostatistical study of zinc content variation (zinc content variograms). Within the circle with 37.5 m radii, surrounding each borehole, resources were evaluated in C1 (indicated) category and up to 75 m in C2 (inferred) category. The boundary of deposit defines the limit of the area on which indirect phenomena of mineralization processes were registered (Zn, Pb below cut off limit, marcasite, calcite, barite).
    Po wielu wiekach intensywnej eksploatacji górnośląskich złóż rud cynku i ołowiu nastąpiło znaczne wyczerpanie ich zasobów. Wydobycie rud Zn-Pb prowadzi obecnie tylko kopalnia 'Olkusz-Pomorzany'. Nadzieje na przedłużenie funkcjonowania krajowego górnictwa rud Zn-Pb wiąże się z niezagospodarowanymi złożami rejonu olkuskiego i zawierciańskiego. Udokumentowano je w latach 1970-1990 ubiegłego wieku. Złoża badano pionowymi otworami z powierzchni, ustalając kategorię rozpoznania w zależności od gęstości sieci wierceń. Zasoby złóż liczono metodą wieloboków Bołdyriewa. Zakłada ona, że wartości parametrów interwałów rudnych określone w otworze centralnym dotyczą także całego wieloboku. Przyjęty schemat nie budził zastrzeżeń w trakcie eksploatacji bogatych, ciągłych na znacznej przestrzeni ciał rudnych występujących w centralnych rejonach górnośląskiego zagłębia kruszcowego. Niezagospodarowane złoża rejonu olkuskiego i zawierciańskiego usytuowane są w peryferyjnych częściach regionu. Z rozpoznania wiertniczego wynika, że mineralizacja Zn-Pb występuje w nich przede wszystkim w formie rozproszonych w planie i w pionie skupień gniazdowych. Przy założeniu gniazdowego modelu złóż koniecznym stało się odejście od tradycyjnych metod ich dokumentowania. Zaproponowano procedurę szacowania zasobów takich złóż, polegającą na ekstrapolacji informacji z otworów pozytywnych do odległości wynikającej z promienia autokorelacji (zasięgu wpływu informacji). Wyznaczono go na podstawie wyników badań geostatystycznych modeli zmienności zawartości cynku w złożach eksploatowanych. Przyjęto, że zasoby szacowane są w otoczeniu otworów rozpoznawczych w obrębie okręgów o promieniu 37,5m w kategorii C1 i w odległości do 75 m w kategorii C2. Granice obszaru złożowego wyznacza kontur obszaru, w którym stwierdzono pośrednie oznaki mineralizacji.

    Opis:
    Mining activities can cause tangible socio-economic improvements in the surrounding regions. Such potential has not been fully realized, owing to the fact that the socio-economic impact assessment processes exercised in India merely predict the footprint of industrial activity on the surrounding population. Consequently, project proponents are mandated to implement a management plan in cases of foreseeable negative consequences. However, both, the assessment study, as well as the process of implementation of a management plan, are riddled with significant gaps and limitations. Primary data collected for this research makes it apparent that, in comparison to the revenue generated from the mining activities, the pace of development of the mine-affected areas and the socio-economic conditions of those residing in these areas are disproportional. Moreover, the current assessment process was found to be lacking in data and analysis. In this context, this paper recommends the usage of state-of-the-art technologies, including unmanned aerial vehicle (UAV) or drone technology, for accurate assessment as well as real-time monitoring of the socio-economic impact of mining operations. The overall objective is to improve the perception of the general population towards the mining industry.
