A technológiai fejlődés hatása a tartós eszközök gazdasági értékcsökkenésére (The effect of technological progress on economic depreciation of durable assets)

A cikk a tartós eszközök gazdasági értékcsökkenésének elméleti hátterét vizsgálja az eszközökben megtestesülő szolgálatok felemésztődése szempontjából. Ezt a felemésztődést az eszközök kimerülésén és elhasználódásán túl, a gazdasági környezetben megjelenő testet öltő és testet nem öltő technológiai fejlődés következtében fellépő avulás is befolyásolja, mely avulás hatását a cikk részletesen tárgyalja. A technológiai fejlődés következtében fellépő avulásnak igen fontos szerepe van az eszközökhöz, és azok használati módjához legjobban illeszkedő értékcsökkenési minta kirajzolásában, amely alapján meghatározott értékcsökkenés központi eleme a vállalkozások jövedelmének, valamint a vállalkozási output egységköltségének, ami az output árazásának fontos tényezője. Ezáltal az értékcsökkenés meghatározásánál figyelembe vett avulás hatással van a vállalkozás termék és tőkepiaci versenyképességére. ___________ The paper examines the theoretical background of durable asset’s economic depreciation, from the embodied services consumption point of view. This consumption is affected by the exhaustion and deterioration beyond obsolescence which is due to embodied and disembodied technological progress that appears in the economic environment. The effect of obsolescence on the economic depreciation is examined in this paper in detail. The obsolescence due to technological progress has an important role in determining the best fit depreciation pattern to the durable asset and its usage. The economic depreciation is a central component of the company’s income, as well as the unit cost of the company’s output, which is an important element of the output pricing process. Thereby the obsolescence recognised by determining economic depreciation influences the company’s competitiveness on the product and capital markets.

Governance in the European Union - Applying the "trilemma of global politics"

The European Union with its sophisticated institutional system is the most important regional integration on Earth. This tight form of economic integration converges to the level that Dani Rodrik calls hyperglobalization in his model, the political trilemma of globalisation. In our paper we develop the mentioned model and then we apply it to the case of the European Integration. We argue that if we want to maintain the deep integration among member states in the EU we have to pass more and more functions of the nation states to the federation level. In case of the EMU that means that federal fiscal policy is needed which could lead to multi-speed Europe considering new member states’ reluctance to give up their specific institutions.

Non-uniqueness through duality in the von Neumann growth models

Duality can be viewed as the soul of each von Neumann growth model. This is not at all surprising because von Neumann (1955), a mathematical genius, extensively studied quantum mechanics which involves a “dual nature” (electromagnetic waves and discrete corpuscules or light quanta). This may have had some influence on developing his own economic duality concept. The main object of this paper is to restore the spirit of economic duality in the investigations of the multiple von Neumann equilibria. By means of the (ir)reducibility taxonomy in Móczár (1995) the author transforms the primal canonical decomposition given by Bromek (1974) in the von Neumann growth model into the synergistic primal and dual canonical decomposition. This enables us to obtain all the information about the steadily maintainable states of growth sustained by the compatible price-constellations at each distinct expansion factor.

Reducible von Neumann models and uniqueness

This paper can be regarded as a result of basic research on the technological characteristics of the von Neumann models and their consequences. It introduces a new taxonomy of reducible technologies, explores their key distinguishing features, and specifies which ones ensure the uniqueness of von Neumann equilibrium. A comprehensive comparison is also given between the familiar (in)decomposability ideas and the reducibility concepts suggested here. All these are carried out with a modern approach. Simultaneously, the reader may also acquire a complete picture of and guidance on the fundamental von Neumann models here.

A környezethez való jog és a Kiotói Jegyzőkönyv (Right to environment and Kyoto Protocol)

A Kiotói Jegyzőkönyv az 1992-ben Rio de Janeiro-ban megrendezésre került Környezet és Fejlődés Világkonferenciáján elfogadott nyilatkozatának 1997-ben aláírt kiegészítő jegyzőkönyve. A Kiotói Jegyzőkönyvben minden aláíró ország vállalta, hogy egy bizonyos százalékos arányban csökkenti országában a kibocsátott üvegházhatást okozó gázok mennyiségét, ezáltal mérsékelve a globális felmelegedés előrehaladtát. A Jegyzőkönyvhöz az Egyesült Államok és több fejlő ország, mint Kína vagy India gazdasági megfontolásból másrészt politikai szűklátókörűségből nem csatlakozott. Ez azonban a komoly aggályokat vet fel azzal kapcsolatban, hogy a környezetvédelmi szabályokat betartó államok erőfeszítései önmagában elegendőek lesznek-e a globális felmelegedés megállítására, de legalábbis csökkentésére. _____________ The Kyoto Protocol signed in the Japanese city in Kyoto in 1997 is a supplemental document to the United Nations Conference on Environment and Development organized in Rio de Janeiro. In the Kyoto Protocol individual countries have mandatory emissions targets for the greenhouse gases they must meet to slow down global warming. The United States of America, and several developing countries, as China and India did not yet joined the Protocol partly because of economic reasons and other ways because of narrow-minded political interests. This brings up serious doubt weather the efforts of the parties of the Protocol can make any change in the recent global processes.

Az európai uniós támogatások hatékonysága és hatásossága közötti különbség a ROP 1.2 intézkedésnél (The difference between the efficiency and effectiveness of using the EU-subsidies at Regional Operational Program)

A szerző cikkében megpróbál rávilágítani annak fontosságára, hogy az Európai Unióból érkező fejlesztési támogatások hasznosulása és a támogatási rendszer hatékonysága között jelentős különbség van. Ha nem tudjuk hatékonyan és hatásosan felhasználni az Unióból érkező pénzügyi eszközöket, akkor a cél: a kohézió, a konvergencia az Európai Unió régi tagállamainak fejlettségi szintjéhez, jólétéhez még nehezebben és lassabban érhető el. Az uniós támogatások hatékonysága alapvetően a rendelkezésre álló pénz lekötésének, lehívásának arányából, illetve a lekötött, lehívott és esetleg visszafizetett összeg arányából állapítható meg (kvantitatív megközelítés). A támogatások felhasználásának hatékonyságánál bonyolultabb, jóval összetettebb megközelítést igényel a hatásosság fogalma. A felhasználás hatásosságát a projektszinten a támogatás hatására megtermelt hozzáadott értékkel, programszinten a GDP hozzáadott növekedéssel lehet kifejezni. A cikk alapvetően a ROP 1.2 "Turisztikai fogadóképesség javítása" pályázati kiírás nyertes projektjeinél végzett kutatás eredményein keresztül kívánja szemléltetni a projektszintű vagy mikro hatásosság fontosságára (kvalitatív megközelítés). _________ The author tries to highlight the importance the difference between the efficiency and effectiveness of using the EU-subsidies. If Hungary cannot use the financial means of the EU efficiently and effectively, than the goal: cohesion and convergence to the level of the old, developed countries of the EU will be much harder and slowly. The efficiency of the EU-subsidies can be measured by the ratio of the amount of money obliged and the amount of money spent, and by the amount of money withdrawn by the Commission, which is actually lost (quantitative approach). The effectiveness of EU-subsidies needs a much more complicated and complex approach, than the efficiency. The effectiveness of usage on project level can be measured by the "added value" of the project, on program level by the added GDP growth or employment. The article is analysing basically the results of a survey made among the winner project of the application ROP 1.2 (Regional Operational Program 1.2) Improving the capacity for tourism (project level or micro effectiveness – qualitative approach).

Climate change in game theory context

The aim of this paper is to survey the game theory modelling of the behaviour of global players in mitigation and adaptation related to climate change. Three main fields are applied for the specific aspects of temperature rise: behaviour games, CPR problem and negotiation games. The game theory instruments are useful in analyzing strategies in uncertain circumstances, such as the occurrence and impacts of climate change. To analyze the international players’ relations, actions, attitude toward carbon emission, negotiation power and motives, several games are applied for the climate change in this paper. The solution is surveyed, too, for externality problem.

Unintended consequences of crisis management

This contribution attempts to decipher the largely unintended, still predictable consequences of crisis management in the global economy. In a series of improvised, case-bycase and unilaterally demand-focused measures, governments tried to extend the Keynesian arsenal to a system whose basic features are unlike those of the national economy. While the collapse of output and employment, on par with the Great Depression, could indeed be averted, conditions for the resumption of sustainable finance and growth have been undermined.

A simplified implementation of the least squares solution for pairwise comparisons matrices

This is a follow up to "Solution of the least squares method problem of pairwise comparisons matrix" by Bozóki published by this journal in 2008. Familiarity with this paper is essential and assumed. For lower inconsistency and decreased accuracy, our proposed solutions run in seconds instead of days. As such, they may be useful for researchers willing to use the least squares method (LSM) instead of the geometric means (GM) method.

And the first shall be the last

This study analyzes the puzzle of Hungarian economic drifting in a long run perspective. The underlying puzzle for the investigation is why bad policies are invariably popular and good policies unpopular, thus why political and economic rationality never overlap. The first part of the article summarizes in eight points the basic features of the postwar period. Then six lessons are offered, which might be useful for other countries in transition or for students of comparative economics and politics, lessons that can be generalized on the basis of the individual country experience.

On optimal completions of incomplete pairwise comparison matrices

An important variant of a key problem for multi-attribute decision making is considered. We study the extension of the pairwise comparison matrix to the case when only partial information is available: for some pairs no comparison is given. It is natural to define the inconsistency of a partially filled matrix as the inconsistency of its best, completely filled completion. We study here the uniqueness problem of the best completion for two weighting methods, the Eigen-vector Method and the Logarithmic Least Squares Method. In both settings we obtain the same simple graph theoretic characterization of the uniqueness. The optimal completion will be unique if and only if the graph associated with the partially defined matrix is connected. Some numerical experiences are discussed at the end of the paper.

How can economic sociology help business relationship management?

Purpose – By analyzing organizations as social actors and business relationships as social relationships, sociology can improve business relationship management. This paper aims to explore the issues involved. Design/methodology/approach – A business relationship is an interactive exchange between two organizations embedded in a network of business connections. The paper reviews theories of social actions and social actors and the concepts of economic field and embeddedness to illustrate some social dimensions of business relationships. Findings – Social action and social actor theories emphasize that co-operation is always encumbered with conflicts, that consciousness about the relationship is fundamental for both strongly and weakly structured actors, and that actors (people involved in a business relationship) always have some freedom of manoeuvre. The concept of economic field underscores the specificity of each business relationship and the critical need for concrete analysis. The concept of embeddedness highlights that no business relationship is possible without personal bonds. Research limitations/implications – These are the first results of a deeper and broader research directed towards a conceptual model of business relationship management. Practical implications – The paper can help managers to analyze more deeply the social dimensions of business relations with both suppliers and buyers. Consciousness, the ongoing presence of conflicts, the unavoidable role of personal bonds, and interactivity are always relevant in business relationship management. Originality/value – The paper integrates sociological and business marketing approaches. It applies essential sociological theories and concepts to business relationship management.

Hálapénz a magyar egészségügyben = Gratitude money in the Hungarian health sector

A tanulmány szerzői lakossági és orvosi minta kikérdezése alapján arra keresik a választ, hogy a valóságban mennyire elterjedt a hálapénz adása és elfogadása a magyar egészségügyben, miként szóródik az egyes orvosi szakmák között, és mekkora az egyes beavatkozási formák hálapénzára. A kapott eredmények szerint, a hálapénzárak nyilvánossá tételének korlátai ellenére a piac szereplői többé-kevésbé egyöntetűen ítélik meg, mi mennyibe kerül. A szerzők megbecsülik az egy év leforgása alatt kifizetett hálapénz összegét. Ennek alapján arra a következtetésre jutnak, hogy az "átlagorvos" hálapénzből származó bevétele bő másfélszerese hálapénz nélkül vett jövedelmének. __________ The authors examine the incidence, in the Hungarian health sector, of gratitude payments from patients to doctors, based on a questionnaire administered to samples of the public and of the medical profession. They look at how the payments are distributed among the branches of medicine, and what payment is customary for various medical treatments. The survey findings show that although there are constraints on public knowledge of the size of gratitude payments, market actors more or less agree in their estimates of what provisions cost. Based on this, the authors conclude that the income the "average" doctor receives from gratitude payments is at least one-and-a-half times as much as his or her income apart from gratitude money.

A new proportional procedure for the n−person cake−cutting problem

We present a new cake−cutting procedure which guarantees everybody a proportional share according to his own valuation.

A method for solving LSM problems of small size in the AHP

The Analytic Hierarchy Process (AHP) is one of the most popular methods used in Multi-Attribute Decision Making. It provides with ratio-scale measurements of the prioirities of elements on the various leveles of a hierarchy. These priorities are obtained through the pairwise comparisons of elements on one level with reference to each element on the immediate higher level. The Eigenvector Method (EM) and some distance minimizing methods such as the Least Squares Method (LSM), Logarithmic Least Squares Method (LLSM), Weighted Least Squares Method (WLSM) and Chi Squares Method (X2M) are of the tools for computing the priorities of the alternatives. This paper studies a method for generating all the solutions of the LSM problems for 3 × 3 matrices. We observe non-uniqueness and rank reversals by presenting numerical results.
