| The purpose of this study was to evaluate feed intake and develop lactation and weight change curves for Holstein x zebu cows under grazing. Eighteen F1 cows were used, divided into three treatments; 6 were Holstein x Gir (HGI), 6 were Holstein x Guzerat (HGU), and another 6 were Holstein x Nelore (HNE), under the feeding conditions of pasture plus concentrate with 22% of crude protein (CP). To estimate individual feed intake at pasture, 2 markers were used: titanium dioxide to estimate fecal dry matter (DM) excretion, and the indigestible acid detergent fiber (iADF) to estimate individual pasture intake. The Wood (1967) model was used to evaluate milk yield and the parameters were estimated for each genetic group, as follows: HGI =... |

| Avaliaram-se a viabilidade técnica e a rentabilidade de um sistema de produção de leite com gado mestiço, mediante análise de custos e receitas da atividade e avaliação da rentabilidade. Os dados foram obtidos de uma unidade experimental da EPAMIG, situada no município de Felixlândia, MG, e referem-se a dois períodos iguais de um ano cada. As variáveis analisadas foram: rentabilidade nos períodos de análise, custo de cria do bezerro e sua importância sobre a receita da atividade. A viabilidade do sistema foi demonstrada pela rentabilidade de 20,2% no ano 1 e 37,6% no ano 2; a venda dos bezerros à desmama representou 25% da receita total. |

| This paper derives a method to quantify the impact of biofuel on fuel markets, assuming that these markets are dominated by cartel of oil-rich countries, and that prices in these countries are set to maximize the sum of domestic consumer and producer surplus, leading to a wedge between domestic and international fuel prices. We model this behavior by applying the optimal export tax model (henceforth, the cartel-of-nations model) to the fuel markets. Using data from 2007 to calibrate the model, we show that the introduction of biofuels reduces global fossil fuel consumption and international fuel prices by about 1% and 2%, respectively. We identify large differences between the effects of introducing biofuels using the cartel-of-nations model, in contrast... |

| This paper investigates the effect of trade cost changes on the spatial productivity distribution in Korea. Data on gross value added and primary factors for 163 spatial units during 2000-2005 are assembled to estimate local TFP using a value-added function. In our application, we control for agglomeration economies so as to identify factors shifting the regional raw-productivity distribution over time. The TFP estimation results show that the Korean regional economy exhibits constant returns to scale, along with significant localization economies. We find that and trade costs reduction and infrastructure improvement significantly shift to the right all percentile values of the regional productivity distribution, while amenity does not affect the movement... |

| The paper analyses the trade relationships among EU- 15 members and some emerging partners: the NMS, Turkey and China. The EU enlargement to 10 countries has modified quite remarkably the features of agri-food trade in Europe. Some of the NMS, such as Poland, Hungary and the Check Republic, contribute to a large extent to the international agri-food trade and, since the beginning of the process of EU accession, have modified dramatically the exchanges with the EU- 15. More recently, other countries are facing new relationships with the EU: Turkey and China. Turkey is a large Mediterranean country and, as a candidate to the EU accession, enjoys a differential treatment in the agri- food trade relationships with the EU. China can be considered as a new... |

| In Canada many changes have been made, and more are pending, to their grain transportation policies. This package of policy changes has two offsetting impacts on freight rates for Canadian grain producers. The removal of transportation subsidies on grain for export offshore has roughly doubled the cost of transporting grain for the Canadian producer. In addition, the change in pooling points will increase freight rates even more for producers in the eastern part of the prairies. Whether federally owned grain hopper cars are sold to the railways, or to an association of Canadian producers, the cost of the sale is likely to be born by producers through increased freight rates over a number of years. In addition, Canadian producers will bear the cost of... |

| This document describes the Israeli Social Accounting Matrix (SAM) for the year 2004, developed by the Agricultural and Food Policy Group at the University of Hohenheim. The SAM is a part of a larger research project which aims to analyse several economic, trade, and labour policies in the context of economic integration of agriculture between Israel and the West Bank. Data are obtained from various sources in Israel. Sources include the Israeli Central Bureau of Statistics (ICBS), the Central Bank of Israel (CBI), and the Israeli Tax Authority (ITA). Data from sources outside of Israel are used to fill-in some gaps in the domestic reports. External sources include the World Trade Organization (WTO), the Organisation for Economic Co-operation and... |

| We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is quite resilient. Trade may cause an environmentally poor country to drag down" its richer trading partner; in this case, both countries degrade their stocks when these would be preserved under autarky. Alternatively, trade may enable the environmentally richer country to pull up" its partner; in this case both countries preserve their stocks when these would be degraded under autarky. These results rationalize the positions of environmentalists and free-traders. The... |

| Throughout recent year food quality standards have become a ubiquitous phenomenon that nationally and globally influences agri-food markets. With equilibrium models commonly used in the quantitative analysis of market and trade effects, we review possible approaches to modeling standards existent in the literature, elaborate the reasoning behind them and discuss their suitability to reflect "real world" situations. While the modeling approaches identified may respectively depict a specific situation, they may not be appropriate in others. That is they capture certain effects of standards only. With increasing ability to account for the various effects of standards, the modeling approaches become more complex and the data requirements increase. |

| The paper looks at the increasing integration of China into the world market, with a specific focus on agricultural and food trade and on the Italian market. Agricultural trade among Italy and China has been limited to secondary products, especially originated in the livestock sector. However, in the last decade exchanges have been constantly increasing and the set of products changing deeply. Specifically, Italian exports to China have been specialising towards the typical "Made in Italy" processed products, showing a potential market for Italian agricultural and food products. In order to test the opportunity and the risks of the integration of China into the world agro-food markets, some similarity indices have been calculated, with refer to two... |

| In this report, important wheat quality attributes and their links to varietal differences are identified, and their technical and economic importance to the milling and baking industries is examined. Wheat class and grading systems used in the United States and other countries are described, and the relationships between wheat classes and wheat varieties and between physical and wholesomeness attributes and grades are identified. The per bushel prices received by farmers' for their wheat depend on the classes and grades of wheat they produce. However, wheat classes and, to some degree, grades are linked to varietal choices and those choices also affect average per acre yields and year-to-year yield variability. Therefore, this report also examines the... |

| The future role of China in world wheat markets is a compelling and important issue for producers in the Northern Plains. Some analysts have estimated that China will continue to demand large quantities of imported wheat. Others have forecast that China will gradually move to a position where domestic supply will meet the nation's demand for wheat. China's own economists also have conflicting views. Chinese Academy of Agricultural Sciences researchers have predicted that the nation will remain at least self-sufficient and could be a large exporter. China's net imports of grain decreased steadily between 1989 and 1993. Moreover, despite large imports in 1994 and 1995, China has had an overall agricultural trade surplus with the United States during most of... |

| Whilst there is a growing literature of computable general equilibrium (CGE) studies examining the impacts of the current Doha Proposals, estimates for the EU are highly aggregated (i.e., EU15). Employing a detailed baseline scenario and a plausible Doha outcome, we examine the long run costs for the European Union, in particular focusing on Spain. Moreover, we implement recent CAP reforms through explicitly modelling of CAP mechanisms to provide greater credibility in assessing the long run asymmetric budgetary and welfare impacts on EU member states. Our estimates forecast resource substitution effects between Spanish agro-food sectors and resource shifts from agro-food activities into manufacturing and services production. In Spain, the impacts of... |
