| O trabalho teve como objetivo estimar a safra paranaense, que somando as culturas da soja e do milho foi recorde chegando em 2007/08 a 21,2 milhões de toneladas, aliado a isso tem-se uma situação favorável de preços internacionais, que gera resultados positivos para o setor produtivo e permite a recuperação do setor que passou por anos complicados por problemas climáticos e de preços. A estimativa da safra foi realizada com uma amostra de dados que representam 78% da área de soja e 61% da área de milho do Estado do Paraná. Quanto as questões relacionadas a biotecnologia – soja transgênica – RR, os resultados foram os esperados, de que essa é mais uma tecnologia disponível ao produtor e esta evoluindo para ser cada vez mais competitiva com a soja... |

| This paper tests the hypothesis that the net of extraction cost price of a natural resource does not change with volume. The hypothesis is shown to he a consequence of Hotelling’s theory. The tests are performed on equations estimated by a nonparametric regression (ACE), and we show that the usual least squares estimation techniques are not general enough to successfully perform the test. The test rejects the pure form of the Hotelling theory and shows that it is necessary to adjust sale prices for volume sold. |

| The world food and financial crises threaten to undermine the real incomes of urban consumers in eastern and southern Africa. This study investigates patterns in staple food prices, wage rates, and marketing margins for urban consumers in Kenya, Malawi, Mozambique, and Zambia between 1993 and 2009. There is high correlation among wage rate series for various government and private sector categories. We find that average formal sector wages rose at a faster rate than retail maize meal and bread prices in urban Kenya and Zambia between the mid-1990s and 2007. Although the 2007/08 food price crisis partially reversed this trend, the quantities of staple foods affordable per daily wage in urban Kenya and Zambia during the 2008/09 marketing season were still... |

| RESUMEN: El objetivo de este trabajo consiste en analizar el proceso de transmisión de precios a lo largo de la cadena comercial en el sector del tomate en España. Para ello se han considerado el precio percibido por el productor y el pagado por el consumidor. El enfoque metodológico adoptado se basa en la estimación de un Vector de Corrección del Error con umbrales. Los resultados indican que, a largo plazo, los dos precios son homogéneos. Sin embargo, en el corto plazo las reacciones de precios, tanto en velocidad como en magnitud, son asimétricas. Es más, los resultados indican que los detallistas se benefician (en el sentido de que son capaces de aumentar el margen comercial) de cualquier shock, ya sea positivo o negativo, que afecte tanto a las... |

| Canadian exports of beef and live cattle to the United States have increased significantly since the late 1980s. Hog exports have increased since the mid-1990s. Major factors affecting exports of beef, pork, cattle, and hogs from Canada to the United States include the exchange rate, increased Canadian production, U.S.-Canada price differentials, and trade liberalization under the Canada - United States Free Trade Agreement (CUSTA) of 1989. Increased Canadian exports have resulted in small but significant reductions in U.S. domestic prices of beef, pork, and hogs. |

| "CGPRT Crops in the Philippines: A Statistical Profile, 1990-1999" is the eighth in the series of the CGPRT Centre's publications providing specific and wide-ranging agricultural data focusing on coarse grains, pulses, roots and tuber (CGPRT) crops in Asia. An earlier series was published in January 1992 in collaboration with the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD) covering the period 1960-1990. In keeping pace with the previous publication, this updated volume covers eight crops: corn (maize), mungbean, soybean, groundnut, cassava, sweet potato, white potato and rice. Although not a CGPRT crop, rice is the most important crop in the Philippines in terms of area planted and production, hence... |

| Objectives were twofold: Determine key factors influencing preconditioning cost and returns; and determine the premium for age and source verified, preconditioned calves sold at a public livestock market. Data provided by the Samuel Roberts Noble Foundation show preconditioning returns depend significantly on number of days preconditioned, average daily gain, and cost of vaccinations, hay, feed, and mineral. Noble Foundation cooperators received a premium for age and source verified, preconditioned feeder cattle when sold at market. Significant coefficients averaged across five sales conclude that Noble Foundation management practices receive a $2.49/cwt premium when compared to all other cattle sold at market. |
