Írásunk a Public-Private Partnership (PPP) magyarországi megvalósulásának hangsúlyairól szól. Azt vizsgáljuk, hogy a szakmai közvélemény milyen képet alakíthatott ki e projektekről a szaksajtó olvasásán keresztül. Három tágabb elvi szempont sajtóbeli megjelenésének súlyát elemezzük: a PPP céljai, a feladatok hatékonyabb elvégzésének módja, illetve a társadalmi kontroll megvalósulása áll érdeklődésünk középpontjában. A tartalomelemzés matematikai-statisztikai módszereit alkalmazzuk. Következtetésünk, hogy a PPP-projektek általában még nem elvi lényegük szerint valósultak meg Magyarországon, bár az évek során érzékelhető pozitív irányú elmozdulás: tanulási folyamat történik. Ennek alapján nem szabad a PPP-t mint módszert elvetni a közfeladatok ellátásában, hanem alkalmazási módjának tökéletesítésére kell törekedni. = This working paper focuses on the perceptions of the Hungarian implementation of Public-Private Partnership (PPP) projects. It was examined how PPP was perceived in the wider public through the communication of the most read daily and weekly business journals. We analyzed the proportion of three broad aspects in the articles: the main goals of PPP, efficiency improvement as a substantial opportunity for value creation, and the role of democratic control. We applied the mathematical-statistical methods of content analysis. Our conclusion is that PPP-projects in Hungary are far from the normative model of implementation as discerned from literature, but from year to year a positive shift, a learning process can be observed. Therefore, instead of discarding PPP as a progressive government solution, Hungary should focus on improving the design and implementation of PPP projects.

The aim of this article is to draw attention to calculations on the environmental effects of agriculture and to the definition of marginal agricultural yield. When calculating the environmental impacts of agricultural activities, the real environmental load generated by agriculture is not revealed properly through ecological footprint indicators, as the type of agricultural farming (thus the nature of the pollution it creates) is not incorporated in the calculation. It is commonly known that extensive farming uses relatively small amounts of labor and capital. It produces a lower yield per unit of land and thus requires more land than intensive farming practices to produce similar yields, so it has a larger crop and grazing footprint. However, intensive farms, to achieve higher yields, apply fertilizers, insecticides, herbicides, etc., and cultivation and harvesting are often mechanized. In this study, the focus is on highlighting the differences in the environmental impacts of extensive and intensive farming practices through a statistical analysis of the factors determining agricultural yield. A marginal function is constructed for the relation between chemical fertilizer use and yield per unit fertilizer input. Furthermore, a proposal is presented for how calculation of the yield factor could possibly be improved. The yield factor used in the calculation of biocapacity is not the marginal yield for a given area, but is calculated from the real and actual yields, and this way biocapacity and the ecological footprint for cropland are equivalent. Calculations for cropland biocapacity do not show the area needed for sustainable production, but rather the actual land area used for agricultural production. The proposal the authors present is a modification of the yield factor and also the changed biocapacity is calculated. The results of statistical analyses reveal the need for a clarification of the methodology for calculating marginal yield, which could clearly contribute to assessing the real environmental impacts of agriculture.

The lecture has two parts. The first part – based upon Eurobarometer data - briefly investigates the proportion and social characteristics of potential entrepreneurs in European comparative perspective. It proves that the Hungarian data are close to the European average. The second part – based on Hungarian panel data (1992-2007) - examines the predictive force of entrepreneurial inclination upon future entrepreneurial career and well-being. The results reveal that potential and actual entrepreneurship have strong social similarities and lasting connections despite the great volatility of both. Entrepreneurial inclination and more concrete plans have influenced the entrepreneurial career chances with nearly identical force, without cancelling each other’s effect. Entrepreneurial motivation has also to do with subjective well-being. The “push” factors of initial dissatisfaction with work and material conditions have lost their significance while the connection between entrepreneurial inclination and satisfaction with future perspectives persists in the longer run. The matrix of original motivation and further career provides a typology of four economic actors: that of “conscious” employees, “blocked”, “forced” and „conscious” entrepreneurs.
