Última KÉNYSZERŰ ÉRTÉKVESZTÉS A MEZŐGAZDASÁGI TERMÉKEK PIACÁN AgEcon Varga, Tibor. Witnessing the long-standing resource insufficiency in Hungarian agriculture, the question arises: aside from obviously low efficiencies, to what extent have unfavorable prices led to this situation. In my presentation I will try to answer the question whether, assuming some kind of value-categories or other as given and measured against this, the permanent erosion of agricultural prices can be established. If so, could declining prices be connected to specific features of the agricultural sector? These answers may be useful for experts in make arrangements for decisions of agricultural policy. Research on micro-economic principles, shows that for an analysis of the value-distortion of our prices the equilibrium prices of the so-called “Walras market” (a...

Ano: 2008 URL: http://purl.umn.edu/43333 Vertical price transmission between market operators in Hungarian agricultural product chains AgEcon Varga, Tibor. Price transmission studies related to the cointegration of price time series are a suitable means for studying market dominance at the various market levels in the food product chains. For this study a price transmission asymmetry study was carried out for 18 commercial food product chains. In this study a monthly price time series was used for the period 2001 to 2005. It was found that there is significant product variation in market dominance which spans the entire industry. However, the variation is not significantly linked to either sectors or vertical levels. At times it is unstable and can easily tilt toward the vertical partner level. Depending on price changes, it can also vary, which, in turn, reflects changes in weather conditions. Following a...

Ano: 2007 URL: http://purl.umn.edu/47014 International wheat price volatility and the increasing export of Russia, Kazakhstan and Ukraine AgEcon Kemeny, Gabor; Fogarasi, Jozsef; Varga, Tibor; Toth, Orsolya; Toth, Kristof. Increasing price volatility of agricultural commodities over the last decade has focused a growing body of literature to identify the influencing factors of price variability. We analyze the effect of increasing wheat export from the Former Soviet Union (FSU) countries to the international wheat market and price volatility. The major wheat producer and exporter FSU countries, Russia, Ukraine and Kazakhstan have experienced increasing share on the international wheat market. An ordinary least square method is applied to estimate the influence of wheat export from Russia, Ukraine and Kazakhstan on the international wheat price volatility. We found evidence of positive relationship between international wheat price and the expanding net wheat export from FSU.

Ano: 2012 URL: http://purl.umn.edu/122550 A FONTOSABB HAZAI TERMÉKPÁLYÁK ÁRALKUINAK JELLEMZŐI AgEcon Varga, Tibor; Tunyogine Nechay, Veronika; Kemeny, Gabor. A termékpályák tagoltsága, a termékpálya-fázisok eltérő koncentráltságából fakadó piaci formák a tevékenységi láncban kialakult áralkukat, valamint az elérhet ő árnyereséget, illetve árveszteséget meghatározzák. A számítási eredményeket a piac szereplőinek véleményével ütköztető vizsgálataink megerősítik, hogy a termékek túlnyomó részénél az erőfölény a legkoncentráltabb oldalnál, a kereskedelmi fázisban található. A kiskereskedelmi láncok nem csak egyértelműen árvezetők, de egyben a feldolgozott termékek importárain keresztül az egész vertikum áralakulását meghatározzák. A termelői és feldolgozói fázis között – nagyon kevés kivétellel – az árnyereség a feldolgozóknál figyelhető meg. Az ágazati szintű erőfölény vizsgálataink szerint termékenként erősen...
