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.

Ez az esszé a teljesség igénye nélkül kísérli meg áttekinteni azt, hogy mire vezetett a közgazdaságtan világméretekben megindult és a 2008-2009. évi válság lezáratlansága miatt vélhetően évtizedes szinten zajló önvizsgálata. A tudományszak egészét egyszerre jellemzi egyfajta tartalmi kiüresedés és a társtudományokkal való erőteljesebb kapcsolatkeresés, a módszertanok és az iskolák egymás mellett élése - ami egyáltalán nem békés -, valamint a gyakorlat által felvetett kérdések elméleti általánosításának igénye. A magyar közgazdaságtan hagyományos követő szerepe megmaradt, viszont a képzésben szerzett negyedszázados tapasztalatok és az új globális kihívások lényegi átalakításokat indokolnának a mai, túlságosan egységesített képzésben. _____ This essay joins the soul-searching that has developed globally among economists since the financial crisis of 2008-2009, whose still open-ended outcomes make it likely that such self-critical reassessments will continue in the years to come. Economics is marked by the parallel existence of substantive hollowing and in-creased reliance on interfaces with neighbouring disciplines. So the plurality and none-too-peaceful coexistence of schools and methodologies is likely to persist. Similarly abundant are the attempts to theorize and generalize new phenomena in policy and business practices. Hungarian economics continues to be a follower - a trend-taker rather than trend-setter - as it was in the inter-war period. Experience has been accumulating for over 25 years in introducing Western-style higher education in economics. The increase of student numbers and steep decrease in public funding thereof call for major restructuring in curricula, institutions and teaching methods and styles alike.
