Content available remote O "metamorfozach" ekonomii dobrobytu
100%
W artykule naszkicowano historię ekonomii dobrobytu (ED), podkreślając "hybrydowy" charakter tej koncepcji teoretycznej i odwieczne swary dotykające racji naukowego bytu tej konstrukcji myślowej, głównie "starej ED" - "normatywnej herezji", pozbawionej mocy objaśniającej ("folklor" omawianej tematyki). Impulsem do zaistnienia "nowej" ED była idea porządku Pareta i ordynalnego ujęcia użyteczności. Od czasów "wczesnego Arrowa" środek ciężkości "nowej" ED przesuwa się w kierunku teorii wyboru społecznego, agregacji preferencji, a następnie: polityki energetycznej, bio-ekonomii i ekonomii środowiska. Celem pracy jest zwrócenie uwagi na "horyzontalną mutację" ED. Idee trwałości (sustainability) rozwoju ekonomiczno-społecznego można włączyć do obszaru badawczego "najnowszej" ED: "Dynamic Welfare Eonomics" (Goeffreya Heala), "New Welfare Economics for Sustainability" (Johna Gowdy'ego). W pracy przywołano klasyczne koncepcje Hotellinga, Hartwicka i Solowa, dylemat granic zastępowalności (weak vs strong sustainability), "zielone" mutacje kanonicznych reguł ekonomicznych oraz podkreślono rolę technik dyskonta.(abstrakt oryginalny)

Content available remote Welfare State in Central and Eastern Europe
100%
This study aims at analyzing the existing welfare state models in Europe and investigating welfare regimes in the countries of Central and Eastern Europe. The hierarchical cluster analysis, employed in this study, revealed that five welfare state models can be distinguished in this region. The analysis also revealed that Central and Eastern European countries are too diverse to form a single cluster, and thus two models of the welfare state - the Eastern Europe welfare model and the Central Europe welfare model - could be distinguished. Meanwhile, while investigating the situation of Central and Eastern European countries in the more general European context, it was observed that Central European welfare model is closer to the old European countries, while the Eastern European welfare model is very different from all other models.(original abstract)
Ocena skuteczności polityki pieniężnej i fiskalnej jest często przeprowadzana na podstawie mnożników polityki pieniężnej i polityki fiskalnej. W artykule ocena skuteczności polityki pieniężnej i fiskalnej zostanie wykonana na podstawie teorii sterowania optymalnego. W celu oceny skuteczności zostaną porównane oczekiwane koszty dobrobytu w trzech przypadkach: oba instrumenty polityki pieniężnej i fiskalnej określone na podstawie sterowania ze sprzężeniem zwrotnym, jak również jeden z instrumentów określony na podstawie reguły ze sprzężeniem zwrotnym, natomiast drugi jako instrument pasywny.(abstrakt oryginalny)
It seemed that since Rothbard's 2008 [1956] exquisite Toward a Reconstruction of Utility and Welfare Economics, one can make a case for the free market based on some modified concept of efficiency. Rothbard famously argued that being equipped with the notions of Pareto-superior moves and demonstrated preference suffices for the above purpose. Our agenda in the present paper is purely negative. First, we face the challenge - in our opinion, inadequately addressed in Austrian literature so far - of sharply defining Pareto-superior moves; to wit, how to evaluate whether a Pareto-superior move occurs; or, more specifically, what is the standard of comparison which would allow us to determine whether a given action constitutes a Pareto-superior move or not. Thus, we sieve out any approaches to social welfare that would be either trivial and therefore uninteresting and the ones that would be irreconcilable with fundamental Austrian premises e.g., ordinal value scales and therefore non-aggregation of utility, etc.. As a result, we seemingly end up with what might constitute a specifically Austrian view on welfare, which non-surprisingly coincides with the actual positions taken by contemporary prominent Austrians themselves for instance, see: Gordon, 1993; Herbener, 1997; Block 1995. Yet, the main thrust of our paper is to argue that this very position cannot withstand criticism, for it either makes an intuitively wrong prediction as we demonstrate in our thought experiment or it vitiates the argument for the free market from the concept of Pareto-efficiency.

The objective of the paper is to reveal the optimal organization of industry when firms, facing externalities, compete or cooperate in R&D as well as in the final output market. The model hinges on a two-stage game setting. A ranking of solutions is established for alternative organizations. We focus on welfare issues and allow for public intervention. Subsidizing R&D is used to draw the industry to match the social welfare solution. The paper shows that targeting the optimal level of R&D leaves final output fall short of the welfare solution. Whereas targeting the final output leads to overinvestment in R&D. The ranking of policies reveals that the most efficient industry organization occurs when firms cooperate and fully share R&D results, but remain competitive in the final good market.(original abstract)
Celem pracy jest analiza kształtowania się dobrobytu ekonomicznego w rozumieniu terminu welfare. W pracy poddana zostanie weryfikacji hipoteza o zależności poziomu dobrobytu od podstawowych charakterystyk gospodarstwa domowego oraz o użyteczności zastosowania wspomnianego podejścia do analizy dobrobytu na podstawie danych z budżetów gospodarstw domowych. (fragment tekstu)
Już na wstępie artykułu konieczne jest zdefiniowanie perspektywy oceny analizy kosztów i korzyści. Otóż jest to perspektywa nakazująca - poprzez weryfikację podstawy i przesłania owej analizy - na duże ograniczenie jej stosowalności w procesach decyzyjnych sfery publicznej. Celem artykułu jest zatem krytyka samej istoty analizy kosztów i korzyści, a nie jej problemów „technicznych", z natury wtórnych w stosunku do poruszanego zagadnienia. Inaczej mówiąc, przedmiotem zainteresowania nie jest odpowiedź na pytanie, jak najlepiej przeprowadzić analizę, a więc również jakich „błędów w sztuce" należy unikać, ale dlaczego jest ona już w swych założeniach ideą wysoce kontrowersyjną.

Content available remote Zrównoważony rozwój w świetle wybranych teorii ekonomicznych
75%
W ciągu ostatnich dwóch dekad pojęcie zrównoważonego rozwoju (ZR) stało się bardzo popularnym elementem współczesnych debat o stanie zarówno środowiska naturalnego, jak i gospodarek na całym świecie. Choć opinie na temat wpływu działalności gospodarczej człowieka na stan środowiska naturalnego są bardzo podzielone, to coraz częściej słychać głosy, że we współczesnej ekonomii powinno się go uwzględniać. Opracowanie to ma na celu interpretację pojęcia zrównoważonego rozwoju w trzech wybranych teoriach ekonomicznych - ekonomii dobrobytu, ekonomii postkeynesowskiej oraz ekonomii sektora publicznego.

Content available remote New Dimension of the Efficiency-Versus-Equity Debate
75%
Trwająca od dawna dyskusja na temat efektywności i sprawiedliwości uzyskała nowy wymiar w trakcie ostatniej dekady. Okazało się bowiem, że niektóre spośród problemów globalnych - takich jak zmiany klimatyczne - potrzebują wyjątkowo długiego horyzontu czasu, co wymaga nowego spojrzenia na sprawiedliwość międzypokoleniową. Wywołało to potrzebę nowego spojrzenia na analizę ekonomicznych kosztów i korzyści. W artykule podjęto dwa problemy wymagające szczególnego zainteresowania: kryteria dobrobytu dla długookresowych ścieżek rozwoju oraz stopy społecznego dyskonta. (abstrakt oryginalny)
W artykule zaprezentowano wybrane zagadnienia związane z współczesnymi analizami koniunktury. Z przedstawionych wyników badań wynika konkluzja, że wyizolowanie gospodarki krajowej z dynamicznego systemu gospodarki światowej mogłoby doprowadzić do nieodwracalnych, negatywnych konsekwencji dla poziomu krajowego dobrobytu.
With the rapid development of new social and economic structures, commonly referred to as 'information society' and 'knowledge-based economy', modern economic sciences and other social disciplines have faced an entirely new set of cognitive and implementation challenges. The new rules have exerted their impact in practically all of the previously used notions, methods, techniques and algorithms of conduct, both those applied in analytical studies and in practical implementations, to the point that it may reasonably be assumed that the modern sciences are in need of an urgent revision and reinterpretation of the way they perceive the material and symbolic realities, and their understanding of changes in the established forms of social or economic activities. The focus of research presented herein is placed on a promising though probably inadequately analysed concept of the real cost of information acquisition from the third-party sources, i.e. from actors operating under the changed context of information society and knowledge-based economy. This concept represents the main research problem. The first stage of research involved verification of a thesis that, under the changed conditions of information society and knowledge-based economy, the established cost accounting principles need to be redesigned to include a cognitively and methodologically correct representation of the real cost of information acquisition from third-party sources. The second research thesis was formulated as follows: the best fundament for the above redesign is the welfare economics, particularly the associated concept of transaction cost economics, supported by the concept of alternative and social costs. The above two theses were further elaborated into four research hypotheses, formulated as follows: Hypothesis 1. The established forms of costing and cost account sufficient enough to provide proper identification and calculation of the real cost of information acquired from third-party sources, i.e. from actors operating under the changed context of information society and knowledge-based economy. Hypothesis 2. The traditional cost accounting models are possible to extend to include the representation of other costing categories. Hypothesis 3. Types of cost currently unrepresented in cost accounting models should be included in the examination of the real cost of information acquired from third-party sources, i.e. from actors operating under the changed context of information society and knowledge-based economy. Hypothesis 4. The new category of cost, i.e. the real cost of information acquired under the changed context of information society and knowledge-based economy, represent a significant portion of the real cost of such undertakings? The fundamental intention behind this research was not to examine the utility of an extended account of cost, as it seems an obvious conclusion and requires no proof. From the viewpoint of utility for decision-making applications, it may safely be assumed that better designs (i.e. more accurate and detailed representations of real costs) will offer better results. The author of this work was more interested in obtaining a confirmation for the need to introduce such extensions, since it would require a more or less radical departure from the established solutions. The changed conditions brought about by the rise of information society and knowledge-based economy are clearly manifested in the increased demand for information, including that from external sources. Moreover, the acquisition of the latter will naturally generate a new category of costs. The principal intention behind this research was to place due emphasis on the significance of cost associated with the acquisition of third-party information in the changed context of information society and knowledge-based economy, both for cognitive purposes and for detailed applications in the real economy. That defined scope of research was faced with two major types of challenge, namely: •• the concept of gratuitous information and the paradox of pricing for virtual products, typically associated with Internet distribution and virtual economies, and included in model analyses, •• traditional limitations of the microeconomic cost accounting, which tend to reduce the role of such categories as: the transaction costs, the alternative costs, and the various manifestations of social costs. Proper understanding and overcoming of the above challenges was the real moving force behind this research. Being well-aware of their existence and potential impact, the author formulated the main research problem - the identification and evaluation of potential for the assessment of the real costs of information acquired under the changed context of information society and knowledge-based economy. The analyses were performed on a sample of economic entities, including not only enterprises, but also other actors involved in economic activities. Although the latter typically operate on different sets of criteria, they are - nonetheless - expected to display a rational approach to the utilisation of rare economic resources. The first research thesis, postulating the necessity of extending the established cost accounting to include proper (cognitively and methodologically accurate) representation of the real cost incurred in the acquisition of information from third-party sources, seems fairly obvious. The scope of this author's research growing role of information in nearly every aspect of human operation and civilizational development down to cognitive and practical conclusions related to rational management and utilisation of rare economic resources assigned for activities associated with the acquisition of information. In the light of the above arguments and the associated evidence - in the form of factual observations and theoretical explorations - the first research thesis may be considered valid and proven. The second research thesis postulated that any such an extension of the cost account to include the real cost of information acquisition may be based on the principles of welfare economics, particularly the associated concept of transaction cost economics, supported by the concept of alternative and social costs. Verification of this thesis required a thorough review and critical evaluation of professional literature, with strong emphasis on cognitive utility and implementation potential of the already published findings and research observations. This author's research provides a lot of general and detailed conclusions and arguments in favour of the second thesis, attesting to the correct and cohesive form of the statement. In the light of the above, the second research thesis may also be regarded as valid and proven. Further elaborations of the first and second thesis came in the form of four research hypotheses, which were then subject to verification. The first hypothesis was expressed: the established forms of costing and cost account sufficient enough to provide proper identification and calculation of the real cost of information acquired from third-party sources, i.e. from actors operating under the changed context of information society and knowledge-based economy. The above statement was unequivocally falsified. The forms of expenditure associated with the acquisition of information from third-party sources represent a clear departure from the traditional understanding of costs. In effect, the established approach to costs and cost calculation cannot possibly be regarded as sufficient for the identification and estimation of costs incurred in the acquisition of thirdparty sourced information. This critical evaluation of the traditional forms of cost accounting should not be interpreted as voiding them of their undeniably practical values. It should only be taken as a simple statement of their limited utility for the practical demands of identification and estimation of costs of such acquisition. By reducing the scope of such analyses to the limits of traditional cost accounting models, we may lose track of a lot of important real cost items which have their bearing on decision-making processes or on the balance represented in cost-to-benefit analyses of specific endeavours. The second research hypothesis was expressed as follows: it is possible to extend the traditional cost accounting models to include the representation of other costing categories. The statement was successfully verified in the course of this research. It may safely be assumed that there are no cognitive or methodological barriers to bar a successful inclusion of new costing categories. Problems with the new categories are not in their coherency with other items, be it new or already established. They are more likely to emerge in relation to such challenges and barriers as: •• the difficulty in clear and unambiguous identification of certain costs and their practical manifestations, •• limitations and deficiencies of the economic dimensional analyses of expenditures (costs), both those expressed in natural and monetary units, •• difficulties in establishing a fair market price for such items to serve as basis for detailed calculations, •• the largely subjective character of most evaluations based on unconventional methods and approaches to the valuation of this type of costs. The above problems were properly exposed in this research, together with suggestions for further scientific exploration. The author also emphasised the need for an individualised approach to the identification and estimation of the new categories of costs (with each activity examined in separation from others). In addition, based on literature studies of modern economic sciences, particularly the welfare economics and the transaction cost economics, the author concluded that the latter two schools provide a good foundation for the postulated expansion of the established cost accounting formulas to allow for the inclusion of the real cost of information acquisition. The transaction cost economics can be employed not only for the identification of this group of costs, but also for the effective estimation of their levels. The neoclassical economy (and the welfare economics), on the other hand, allows for good recognition of the nature and the economic significance of alternative costs. These represent a category of hypothetical costs which require no real expenditure, but serve to expose and emphasise the alternative and scarce character of economic resources. This, in turn, allows for practical inclusion of alternative costs as part of the established cost accounting and decision-making applications. The welfare economics has also contributed to the proper exposition of another important group of costs - namely, the social costs. As evidenced in numerous empirical studies, practical significance of social costs has grown over the years, and for many reasons: not only due to the variety of their forms and manifestations, but also to the systematic increase of their levels and their practical impact upon the effectiveness of economic endeavours - both in micro- and macro-economic dimension. They also represent real costs, and are often required from economic entities other than the real guilty party. This may generate additional difficulties, both theoretical and practical, in relation to the internalisation of such costs, i.e. their proper attribution to parties held directly responsible for such costs. The above elaborations present a precise response to the third research hypothesis under examination, namely: types of cost currently unrepresented in cost accounting models should be included in the examination of the real cost of information acquired from third-party sources, i.e., from actors operating under the changed context of information society and knowledge-based economy. They not only allowed for the proper identification of their forms and types, but also helped emphasise some of the additional aspects to be included in this type of analyses. For instance, the most important challenges in the context of transaction cost are based on the triad of: identification - classification - valorisation. Even if we manage to properly identify the types of costs, we still need to overcome two important problems associated with the use of transaction cost in micro-economic account calculations, namely: the attribution of their levels in natural units, and their monetary valorisation. These pose their own sets of interesting problems and dilemmas, both from the methodological and the practical (accounting) standpoint. For research hypothesis four - the new category of cost, i.e. the real cost of information acquired under the changed context of information society and knowledge-based economy, represent a significant portion of the real cost of such undertakings - the verification was obtained at levels which may raise reasonable doubts. Based on the available empirical data, the author demonstrated the intensities of certain phenomena associated with the acquisition of thirdparty sourced information, both in micro- and macro-economic dimension. This may be seen as a confirmation attesting to the validity of hypothesis four. Perhaps further verification can be found in the detailed analyses of volumes of the associated costs for individual undertakings or - in an aggregated form - for the economy as a whole. Such an endeavour would surely prove expensive and time-consuming, and would be far beyond the capacities of a single researcher. With proper logistic support, however, the task may be seen as a challenge worthy of further exploration. Apart from the examination and verification of theses and research hypotheses, this work has hopefully brought some order in the understanding of several important cognitive notions. This was a necessary step, dictated by the nature of research material, and the apparent lack of transparency in the commonly adopted definitions. Moreover, the author hopes to have achieved a thorough evaluation of the utilities offered by the concepts of the welfare economics, and modern economic sciences in general, for the practical examination of the real cost of information acquired from third-party sources. Another notable benefit of this approach came as a natural consequence, resulting in a clearer identification of the main research dilemmas and challenges in the studied field, as well as some of the practical obstacles in this context. This forms a good basis for further development of knowledge and skills in more precise identification and estimation of cost associated with the acquisition of third-party sourced information. The implicit objective behind this research and behind this monograph was to place due emphasis on the notion that - in face of the modern rise of information society and knowledge-based economy - the problem of the real cost of information acquired from a third party may prove exceptionally important, not only for cognitive, but also for practical (implementation) reasons and standpoints. The cost of acquisition, or - in a broader sense - the cost associated with the realisation of the information function, will quite soon elevate to be a major measure of effectiveness in any decision-making scenarios and planned endeavours related to information management, or for the entire information management system on the level of individual entities. As such, it will also be of major impact upon the broadly defined effectiveness of information society as such, and of knowledge-based economy in its entirety. Lastly, it may bring important improvements to the existing approach to cost accounting on the macro-structural level. These are the tasks for the immediate future, ones that must be faced quite promptly, both in economic research and in management practice.(original abstract)

Content available remote Improving the Relationship between Welfare Economics and Ethics
75%
In this essay, the essential aspects of Welfare Economics are summarized in order to analyse the possible links with Ethics, and consequently to provide useful suggestions for Economic Policy. The Introduction contains the principles of neoclassical Welfare Economics, without considering the circumstances in which the so-called failures of competitive markets occur. The second part of this paper contains a description of two possible solutions to the problem concerning the integration of Welfare Economics and Ethics. The first solution is the determination of the optimal combination of general competitive equilibrium principles and social ethics ones, without removing the theoretical structure of Welfare Economics. This first proposal, while retaining some economic liberalism principles, assigns a central role to the government, which is delegated to superimpose on the Pareto criterion a distributive justice rule. Another solution, which is suggested by Sen, is essentially directed to modify Welfare Economics by ethical criteria aimed at improving every individual deprivation, and it is based on the distinction between the two concepts of 'utility' and 'agency'. We also proposed exploiting the original considerations written by Smith about social aspects as a useful integration and support to Sen's approach. (original abstract)

Wilfred Beckerman's textbook entitled Economics as Applied Ethics. Value Judgements in Welfare Economics has been published by Palgrave MacMillan. The monograph is intended for students who are completing their studies of economics and are interested in connections between economics and ethics. In the Introduction Beckerman states: "[A]lthough ... the value judgements inherent in welfare economics are not prominent in economic research or education, students of the subject, or politicians, ought not to be left with the impression that economics is a value-free objective science."

In their article published in a recent issue of this journal, Wysocki and Megger 2019 attempt to undermine Rothbard's welfare theory as articulated in his classic essay on the subject 2008. More specifically, they suggest that the theory in question generates some fatally counterintuitive conclusions and relies on viciously circular arguments. In this response, my aim is to demonstrate that while the article under consideration raises some interesting points, the rather monumental task that its authors set themselves - that is, the task of dismantling the whole of Austro-Rothbardian welfare economics - results in failure.

We współczesnych rozważaniach na temat jakości życia, jakość powietrza, którym oddycha człowiek odgrywa bardzo ważną rolę. Nie podlega dyskusji, że w Polsce okres od roku 1990 to czas nadrabiania wieloletnich zaniedbań dotyczących środowiska przyrodniczego. Celem podjętego badania było sprawdzenie czy podjęte działania służące zmniejszeniu emisji zanieczyszczeń do powietrza atmosferycznego były skuteczne i na ile udało się poprawić jego stan i podnieść środowiskową jakość życia społeczeństwa polskiego w tym zakresie. Dla realizacji założonego celu użyto wskaźnika emisji głównych zanieczyszczeń powietrza (do tej grupy zaliczany jest: dwutlenek siarki, tlenek azotu, tlenek i dwutlenek węgla, niemetalowe lotne związki organiczna, amoniak oraz pyły). Wykorzystując dane statystyczne dostępne w rocznikach Ochrona Środowiska przeprowadzono analizę zmian emisji tych związków. W opracowaniu wykorzystano metodę opisową, statystyczną i analityczną. Wykazano, że w analizowanym okresie w większości przypadków znacznie zmniejszyła się emisja głównych zanieczyszczeń powietrza, co bez wątpienia przyczyniło się do poprawy środowiskowej jakości życia.(abstrakt oryginalny)

Historyczne uporządkowanie głównych wątków debaty nad państwem dobrobytu, pozwala postawić zasadnicze pytanie: skoro w każdym z okresów państwo dobrobytu znajdowało się jakoby w ogromnym kryzysie, niekiedy zarysowywanym tak silnie, że jedynym rozsądnym rozwiązaniem wydawało się jego odrzucenie, to dlaczego na początku XXI wieku nadal pozostaje ono dominującym wzorcem organizacji zadań publicznych w sferze socjalnej i ekonomicznej krajów wysoko rozwiniętych? Poszukując uzasadnienia tej trwałości, autor odwołał się do argumentacji natury politycznej, filozoficznej oraz ekonomicznej. (fragment tekstu)

Celem artykułu jest próba udzielenia odpowiedzi na pytanie, jaki charakter ma arbitralność interpersonalnych porównań użyteczności (IPU), które spośród składowych IPU są nośnikami arbitralności oraz próba oceny głównych strategii rozwiązania problemu IPU. Analizując krytykę Lionela Robbinsa wysuniętą w stosunku do IPU, koncepcje kardynalizacji użyteczności, metody IPU oraz dyskusję na temat różnych strategii rozwiązania problemu IPU, dochodzimy do wniosku, że z punktu widzenia zarzutu arbitralności obiektywistyczne strategie rozwiązania problemu IPU nie są gorsze od propozycji konkurencyjnych.(abstrakt oryginalny)
