The objective of the paper is to present the price interdependencies between agricultural commodity products from Ukraine (both export and non-export oriented) and other commodities whose prices are shaped on world markets, with a special focus on the role of their volatility. The research demonstrates a tight connection between the global prices of crude oil and prices of Ukrainian corn and wheat. Additionally, the volatility of world prices of agricultural commodities influenced the Ukrainian national market and had significant impact on domestic price declines. At the same time, the mechanisms for pricing non-export related agricultural commodities are formed mostly under the influence of factors from the domestic market. It is argued that a low interdependency between non-export oriented agricultural commodities and world markets stipulates the social stability of Ukraine's population. (original abstract)

The research aimed to determine the types of external benefits associated with running the vineyard in accordance to with the principles of sustainable production, and then, based on conclusions from the assessment of the development of vineyards growing in Poland under climate change conditions, to examine consumer opinions on their willingness to pay for wine originating from crops that generate positive externalities. It was found that the cultivation of grapes in a sustainable manner is characterized by the existence of external benefits. These benefits result from the local character of public goods, which include primarily the ecosystem described as terroir and related elements such as biodiversity and landscape. They interact in a synergistic way to other external social benefits, such as tourist attractiveness or cultural heritage. It has been shown that viticulture for wine and wine production in Poland is growing rapidly, and climate change will affect further potential development opportunities for this sector. The surveyed consumers pointed out that the wine attributes such as the organic way of production or practices responding to climate change are important for them. For the most part, they are willing to pay for it more than for features related to other external benefits, i.e. biodiversity or landscape. It is argued, that orientation of Polish vineyards to produce in a way that generates external benefits, ie. organically, will allow to take advantage of the network effect which may translate into the desire of consumers to pay a higher price for wine.

W artykule podjęto próbę oceny stanu rozwoju sektora biogospodarki opartej na wiedzy na Ukrainie. Jednocześnie dokonano oceny na ile obecny rozwój wpisuje się w koncepcję systemu dyfuzji innowacji opartą na modelu poczwórnej helisy, oraz wskazano na najważniejsze czynniki sprzyjające i ograniczające ów rozwój. Stwierdzono, iż Ukraina posiada znaczący potencjał czynników wytwórczych dla produkcji biomasy, który dotychczas wykorzystywany jest na potrzeby biogospodarki opartej na wiedzy w znikomym stopniu, czego główną przyczyną jest niski stopień dyfuzji innowacji, głównie w zakresie biotechnologii. Obecny rozwój w niskim stopniu oparty jest na koncepcji poczwórnej helisy, co jednocześnie stanowi o dużym potencjale wzrostu na najbliższe lata. Właściwie ukierunkowana polityka gospodarcza może w znacznym stopniu wpłynąć na rozwój biogospodarki opartej na wiedzy na Ukrainie.
