| The paper explores regional trade integration of the countries involved in the EU eastward enlargement (EU-25) processes distinguishing the possible regional trade clusters within EU-25 that may support integration of the EU-15 and the new member states. We examine whether the gravity equation based on the new trade theory describes trade integration of the EU-25 countries, and whether the results of a gravity model based analysis may be different in the case of the Baltic Sea region (BSR). The gravity models are estimated based on panel data for the years 1993 to 2002. The results of our analysis indicate that the BSR is forming an exception within EU-25. The BSR trade cannot be explained as much with New Trade Theories as in the case of the whole EU. The... |

| We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become... |

| This study examines the effect of European intervention politics in the European butter market in the context of market liberalization using the example of Germany. A heteroscedastic Tobit model is estimated using German butter market data from 1973-2010. There is evidence that price support has reduced price instability in the butter market. Simulation indicates that enhancing intervention price causes an increase in the expected butter price in the long-run, even though if market price is higher than intervention level. We find changing effects of stockpiling. If difference between market and intervention price is small and stock quantity is high, it significantly contributes to reducing price volatility. On the contrary if price difference is large and... |

| The paper aims to explore international trade flows of the countries involved in the EU eastward enlargement processes - the current EU members (EU15) and the candidate countries (CC12). The empirical results of the study allow us to conclude that the behaviour of bilateral trade flows within the countries involved in EU eastward enlargement accords to the normal rules of gravitation, having statistically significant spatial biases caused by the trade relations, between the Baltic Sea Region (BSR) countries (the BSR bias), the border countries (the border bias) and the EU member and candidate countries (the East-West bias). The East-West trade relations are still rather weakly developed and there is a statistically significant difference in international... |

| Das Papier untersucht die Rolle von Frühindikatoren bei der Erstellung von Konjunkturprognosen. Gegenstand der Analyse sind die Fragen: Welche Kriterien sollten Frühindikatoren generell erfüllen bzw. was sollten Frühindikatoren leisten? Inwieweit erfüllen die gängigen Indikatoren diese Anforderungen? Wie ist die Prognosegüte der verschiedenen Frühindikatoren zu beurteilen? Die theoretischen Überlegungen und ökonometrischen Untersuchungen kommen zu dem Ergebnis, dass die gängigen Frühindikatoren die in sie gesetzten Erwartungen nur eingeschränkt erfüllen können. Der Verlauf einzelner Frühindikatoren lässt keine eindeutigen Schlußfolgerungen auf die reale Wirtschaftsentwicklung zu und der Vorlauf der Frühindikatoren vor der realen Entwicklung beträgt... |

| While farmland rental markets are likely to be spatially differentiated, the fine spatial structure of row-crop quality land should have a significant effect on cash rent determination. This study provides a rigorous empirical understanding of the effect of land spatial heterogeneity on cash rental rates. The lacunarity index is employed to measure spatial heterogeneity of land quality, which is built directly upon a soil quality measure, the land parcel’s corn suitability rating index (CSR). A panel data random effect model is applied on annual survey data of farmland cash rental rates of Iowa for 1987-2009. As expected, land spatial heterogeneity has a statistically significant and negative effect on local cash rent rates. The effect’s origin warrants... |

| The transgenic plum (Prunus domestica L.) C5, in which the coat protein (CP) gene of the Plum pox virus (PPV) is inserted, represents a unique example of the use of genetic engineering for fruit crop improvement in Prunus spp. Field trials in Poland, Romania, and Spain have demonstrated resistance of C5 to several D and M strain PPV isolates. In Chile, the quarantine regulations for PPV and for genetically modified (GM) plants require that the testing of C5 for resistance to Chilean PPV isolates be done under controlled isolated conditions. To carry out these tests C5 shoots were multiplied in vitro and micro-grafted onto four Adesoto101 (Prunus insititia L.) rootstock populations that had been previously infected each with one of four Chilean PPV-Ds.... |
