Adaptability of nonlinear equilibrum models to central planning

Linear multisectoral models have for long been applied in the Hungarian national economic planning. Price-quantity correspondences and interaction, however, cannot easily be taken into account in the traditional linear framework. Computable general equilibrium modelers in the West have developed techniques which use extensively price-quantity interdependences. However, since they are usually presented with the controversial strict neoclassical interpretation, the possibility of their adaptation to socialist planning models has been concaled. This paper reflects on some results of a research investigating the possible adaptation of eqailibrium modeling techniques to central planning models.

Price of unsustainability. Economic impacts of climate change

Global problems, rapid and massive regional changes in the 21st century call for genuine long-term, awareness, planning and well focused actions from both national governments and international organizations. This book wishes to contribute to building an innovative path of strategic views in handling the diverse challenges, and more emphatically, the economic impacts of climate change. Although the contributors of this volume represent several approaches, they all rely on some common grounds such as the costbenefit analysis of mitigation and adaptation, and on the need to present an in-depth theoretical and practical dimension. The research accounted for in this book tried to integrate and confront various types of economics approaches and methods, as well as knowledge from game theory to country surveys, from agricultural adaptation to weather bonds, from green tax to historical experience of human adaptation. The various themes and points of views do deserve the attention of the serious academic reader interested in the economics of climate change. We hope to enhance the spread of good solutions resulting from world wide disputes and tested strategic decisions. WAKE UP! It is not just the polar bears' habitat that is endangered, but the entire human form of life.

Európai Unió: túlélés vagy távlati tervezés – az állam változó szerepei (European Union – survival or long term planning?)

Az EU-ban, a mai állapotok szerint, csak „transzferunióról” beszélhetünk és nem egységes piacról. Az eurós pénzfolyamatok eltorzítva közvetítik a versenyképességet is: mind az árukban és vagyontárgyakban, mind – főleg – a pénzügyi eszközökben megtestesült munkákat/teljesítményeket rosszul árazzák. Egy ilyen keretben különösen könnyen alakul ki az, amit potyautas-problémának nevezünk, vagyis ahol tényleges vagy mérhető teljesítményleadás, vagy éppen fizetés nélkül lehet fogyasztani, és túl olcsón lehet szabad forrásokhoz jutni. Az eurózóna számos közvetítő mechanizmusában is tökéletlen. A sok, szuverénadósság-présbe került tagország között van kicsi, közepes és nagy is. Ez a tény, valamint az általános növekedési és munkapiaci problémák, egyértelműen „rendszerszintű zavarokat” jeleznek, amelyeket ebben a dolgozatban teljesítmény közvetítési-átviteli problémának hívunk, és ezért egy szokatlan, ám annál beszédesebb, elektromosenergia-átviteli rendszeranalógiával segítünk értelmezni. Megmutatjuk, hogy egy jó nagyvállalat miért jobb pénzügyi tervező, mint egy azonos méretű állam. _____ Why are ill-defined transfer mechanisms diverting valuable assets and resources to the wrong destination within the EU? Why do we witness ongoing pressure in the EU banking sector and in government finances? We offer an unusual answer to these questions: we apply an analogy from physics (from an electric generation and distribution network) to show the transmission inefficiency and waste, respectively, of the EU distribution mechanisms. We demonstrate that there are inherent flaws in both the measurement and in the distribution of assets and resources amongst the key EU markets: goods, money and factor markets. In addition, we find that when international equalizer mechanism is at work (cohesion funds allocated), many of these equity functions are at risk with respect to their reliable measurement. Especially are at risk the metered load factors, likewise the loss/waste factors. The map of desired outcomes does not match the real outcome, since EUtransfers in general are put to work with low efficiency.

Natura 2000 erdők közgazdasági környezetének elemzése (Assessment of the economic environment of Natura 2000 forests)

Ebben a tanulmányban a Natura 2000 erdők közgazdasági kérdéseit jártuk körül az ökoszisztéma-szolgáltatások koncepciójának segítségével, nemzetközi és hazai szakirodalomra építve. Emellett a természetközeli erdőgazdálkodás fogalomkörét, s azon belül a folyamatos erdőborítást szolgáló erdőgazdálkodást vettük alapul. A következőkben néhány összegző megállapítást teszünk, és kijelölünk további kutatási irányokat. _____ This study has been prepared within the LIFEinFORESTS – Improved communication, cooperation and capacity building for preserving biodiversity in Natura 2000 forests (B2 action, LIFE13 INF/HU/001163) – project in the framework of LIFE+ Information and Communication under the contract signed with the Duna-Ipoly National Park Directorate. The main aim of the study is to summarize the international and Hungarian economic and environmental economic literature related to the Natura 2000 forests, and serve as a background study for the communication with and training of forest owners and users operating at Natura 2000 sites. The concept of ecosystem services (ESs) is used as an overall framework for the study. In our opinion it is able to show all the benefits provided by forests and can also help to reveal that the benefits of nature-oriented, continuous cover forest management (CCF) can exceed the benefits of traditional rotation forest management (RFM). The definition and the classification of the Millennium Ecosystem Assessment (MA, 2003, 2005) is used throughout the study, so provisioning, cultural, regulating and supporting services are distinguished.
