DYNAMICS OF POLISH WHEAT PRICES IN COMPARISON TO SELECTED WORLD PRICES IN A PERIOD OF ECONOMIC TRANSFORMATION

Poland's market reforms implemented in 1990 should possibly result in increasing price linkages between Polish and internationally traded agricultural commodities like wheat. Using regression and cointegration analysis Polish monthly wheat prices were found to be generally unrelated to selected world prices over the period of 1990/91 through 1996/97 mainly because of Polish government's intervention.Poland, price analysis, intervention price policy, wheat, Crop Production/Industries, Demand and Price Analysis,

How government policies affect the relationship between Polish and world wheat prices

Cash prices for wheat in Poland are not closely related to futures prices in Chicago and London, for several reasons: differences in seasonality, fluctuations in exchange rate, poor dissemination of information in Poland, and most important the Polish government's intervention in wheat markets. Polish wheat prices generally move to expected intervention prices and then stay there until the next intervention level becomes known. The exception was in 1994-95, when sharply higher world prices raised prices in Poland. A wheat futures exchange in Poland could give the private sector a tool for hedging against price risk, improving efficiency and price discovery in Poland. It would be difficult to develop, however, under present interventionist policies. This situation could be improved by reducing the protection of prices and by making any intervention rules-based (reducing uncertainty about policies). Should intervention be reduced or rationalized, the next question is whether Poland needs its own wheat futures exchange or whether Poland's private sector can use futures exchanges in London and Chicago to hedge against risk. The answer to that question is not an easy one.Markets and Market Access,Payment Systems&Infrastructure,Environmental Economics&Policies,Labor Policies,Insurance&Risk Mitigation,Markets and Market Access,Access to Markets,Environmental Economics&Policies,Insurance&Risk Mitigation,Financial Intermediation

Nonlinear multiscale modelling of quasi-solid state behaviour of PET/MWCNT nanocomposites : 3D RVE-based approach

Nonlinear 3D RVE-based computational multiscale model for prediction of the quasi-solid state behaviour of PET/MWCNT nanocomposites is proposed in this work. The model links the time and length scale of representative morphology of the nanocomposite with the corresponding macroscopic scales via the numerical homogenisation. Finite Element simulations of the uniaxial extension of the nanocomposite near the glass transition show that the addition of MWCNTs leads to significant stiffening of PET. It is caused by an excellent reinforcing ability of the nanotubes, which on average are found to carry the load around two orders of magnitude larger than the matrix. A significant decrease of nanocomposite stresses with increasing processing temperature in its narrow range near the glass transition is also predicted by the model

Tradycyjne produkty żywnościowe w Polsce w świetle obecnych trendów konsumenckich i innowacyjnych trendów producenckich w produktach żywnościowych

Recently in the EU food markets there have appeared legally recognized products defined as traditional ones. In Poland, the Ministerial list of traditional food products (TFPs) represents a very wide spectrum of items (over 1,600 in October 2016) ranging from generic agricultural products to specific food dishes and meals. In the article an attempt to assess market attractiveness of this type of products in the light of the current consumer and international food product innovation trends was undertaken. Using the Lancaster approach to analyze attributes of the Polish TFPs it was found that they can be treated as a kind of marketing innovations, which are in line with some consumer as well as food product innovations trends. Consequently, this indicates certain marketing opportunities to be possibly taken by local food producers.Ostatnio na rynkach żywnościowych UE pojawiły się prawnie uznane produkty zdefiiowane jako tradycyjne. W Polsce ministerialna lista tradycyjnych produktów żywnościowych (TFPs) reprezentuje bardzo szerokie spektrum pozycji (ponad 1600 w październiku 2016 roku) od generycznych produktów rolnych do specyfiznych potraw i dań. W artykule podjęto próbę oceny rynkowej atrakcyjności tego rodzaju produktów w świetle obecnych trendów konsumenckich oraz innowacyjnych trendów w produktach żywnościowych. Wykorzystując podejście Lancastera w analizie atrybutów polskich TFPs stwierdzono, że mogą być one taktowane jako pewien rodzaj innowacji marketingowych zbieżnych z niektórymi trendami konsumenckimi i innowacyjnych trendami w produktach żywnościowych. W konsekwencji oznacza to pewne marketingowe szanse, które mogą być wykorzystane przez lokalnych producentów żywności
