This paper shows that corn-ethanol policies generate far greater carbon leakage in the fuel market itself. Hence, corn-ethanol does not meet EPA’s threshold, regardless of ethanol policy and whether one includes emissions from land use change. https://roaae.org/wp-content/uploads/2014/11/RAAE_02_2013_Drabik_deGorter.pdf biofuels ethanol carbon leakage emissions savings tax credit mandate eng Faculty of Economics and Management of the Slovak Agricultural University in Nitra and the Association of Agricultural Economists in Slovakia Review of Agricultural and Applied Economics 1336-9261 2013-09-30 16 2 16 23 10.15414/raae.2013.16.02.16-23 250-1 article Miroslava Rajcaniova Jan Pokrivcak This paper examines price transmission mechanism between farm and retail levels in vertical chain of potatoes. Time series analysis starting with cointegration approach is used to study price linkages between producer and consumer prices in potato market in Slovakia. We test for an existence of structural break in time series data (Gregory - Hansen test) in the observed period and allow for an existence of non-linear relationship between prices at various levels of vertical chain by using threshold autoregressive models. We found an evidence of structural break and existence of asymmetry in price transmission along the potato supply chain. https://roaae.org/wp-content/uploads/2014/11/RAAE_02_2013_Rajcaniova_Pokrivcak.pdf price asymmetry transmission cointegration potatoes eng Faculty of Economics and Management of the Slovak Agricultural University in Nitra and the Association of Agricultural Economists in Slovakia Review of Agricultural and Applied Economics 1336-9261 2013-09-30 16 2 24 39 10.15414/raae.2013.16.02.24-39 250-1 article Shailesh Shrestha Pavel Ciaian Mihaly Himics Benjamin Van Doorslaer The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application) simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation. https://roaae.org/wp-content/uploads/2014/11/RAAE_02_2013_Shrestha_et_al.pdf climate change agricultural productivity adaptation Europe eng Faculty of Economics and Management of the Slovak Agricultural University in Nitra and the Association of Agricultural Economists in Slovakia Review of Agricultural and Applied Economics 1336-9261 2013-09-30 16 2 40 49 10.15414/raae.2013.16.02.40-49 250-1 article Tomáš Ratinger Miluše Abrahamová Jan Boudný Iveta Boškova Ivan Foltýn Martin Hruška Jaroslav Pražan Václav Voltr Grasslands received policy attention in the Czech Republic only just fifteen years ago, when they were threatened to be abandoned in the economic transition process. The supports to farming on grasslands have grown gradually, particularly after the EU accession. The policy followed the notion of jointness between grassland management and beef cattle raising and conditioned Agri-environmental (AE) and Less Favoured Areas (LFA) payments by a minimum livestock density. There are many reasons why the current policy will change in the new programme period. This paper attempts to assess the impact of the envisaged changes on grassland maintenance. It is showed that overall future supports to farming will be sufficient to keep positive profit on grassland farms, however the structure of supports might be less appropriate to the actual objectives of grassland protection and hence, there is a threat of policy failure in the end. https://roaae.org/wp-content/uploads/2014/11/RAAE_02_2013_Ratinger_et_al.pdf grasslands beef cattle mathematic programming model
