| La producción de jitomate es una de las actividades agrícolas más importantes y generadoras de ingreso en México. Sin embargo, existen problemas técnicos y económicos a los que se enfrenta tanto en el proceso de producción como de comercialización. El objetivo de este estudio fue identificar los sistemas de producción del cultivo de jitomate en el estado de Jalisco, para conocer la lógica de producción y distribución a los diferentes mercados, así como los factores que determinan la permanencia del sistema productivo. Los resultados indican que la producción se localiza en: Sayula, La Ciénega, Sierra de Amula, Costa Sur, y Zapotlán El Grande. 84% de los productores utilizó el sistema a campo abierto, 8% bajo invernadero, 4% con malla sombra y 4% combina... |

| The objective this paper is to analyze the relationships in the prices on the tomatoes wholesale market prices of Fortaleza (CE), Ibiapaba (CE), Recife (PE) e Salvador (BA). Time series methods were used: unit root test, Johansen co-integration test, VAR models, and variance decomposition of prediction error and impulse response function. The results showed that the prices of Fortaleza influencies the wholesale market of Ibiapaba (CE), Recife (PE) e Salvador (BA). |

| In this paper we analyse price transmission for the carrot, parsley, tomato, green pepper and potato markets. Although there is a dual farm structure dominated by small individual farms, our results imply that price information flows from the producer to the retail level for potatoes, parsley and carrots. Our results also suggest that farmers do not merely accept prices, but can actually influence market prices. Tomato and green pepper prices have large transmission elasticities, and causality runs from the retail to producer level. It therefore follows that tomato and green pepper producers tend to accept prices and that the sector’s prices are determined by upper market levels (processors, wholesalers, retailers). These results are reinforced by the fact... |

| Globalization and trade liberalization have exposed agricultural sector of many developing countries to sudden disturbances, caused not just by demand-supply conditions within their economies but also by volatility in global commodity prices, exchange rate and surge in imports. This paper evaluates the magnitude of sensitivity of Indian agriculture to these factors, and explores policy options that may neutralize their adverse effects, maintain price incentives and stability. The analysis is undertaken for one important tradable commodity viz. wheat by applying a structural econometric model, separately under the exportable and importable scenarios from 1980-81 to 2009-10. Findings reveal wheat to be increasingly driven by an incentive structure based on... |

| The elasticity of price transmission measures the extent to which a change in world prices will be transmitted to an importing country, with an elasticity of less than one being attributed to trade barriers. Recent research highlights the role that multinational trading companies may play in impeding price transmission. Further, in markets characterised by monopolistic competition an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper the potential for market structure to affect price transmission and trade elasticities is demonstrated. The elasticity of price transmission has been central to a revised approach to estimation of trade elasticities and has been... |

| This study aims to analyze the relations of causality and price transmission of the cassava root, the cassava starch, the cassava flour, the wheat, the wheat flour and the corn, in the State of Parana. The used data goes from January 1995 to December 2005, with monthly regularity. It was applied the methodology of Granger causality to test the relations between the variables. The results showed long term relations between corn and cassava root prices, cassava starch and cassava flour prices, wheat and corn prices and wheat and wheat flour prices. It was emphasized the dependence of the cassava root prices in relation to corn, wheat, cassava starch and cassava flour prices and its little influence on these variables. It was also noted that cassava flour... |

| Price transmission studies related to the cointegration of price time series are a suitable means for studying market dominance at the various market levels in the food product chains. For this study a price transmission asymmetry study was carried out for 18 commercial food product chains. In this study a monthly price time series was used for the period 2001 to 2005. It was found that there is significant product variation in market dominance which spans the entire industry. However, the variation is not significantly linked to either sectors or vertical levels. At times it is unstable and can easily tilt toward the vertical partner level. Depending on price changes, it can also vary, which, in turn, reflects changes in weather conditions. Following a... |

| Resumen El análisis de las relaciones de precios existentes en un determinado sector permiten, por un lado, ofrecer una idea aproximada del funcionamiento de los mercados y, por otro, anticipar respuestas ante shocks inesperados en mercados relacionados. El objetivo de este estudio se ha centrado en el análisis de la transmisión de precios entre los principales mercados de ovino en España. Para llevar a cabo este estudio se ha adoptado un enfoque econométrico que ha tenido en cuenta las propiedades estocásticas de las series, la posible naturaleza multivariante de los procesos de transmisión, y la distinción entre el comportamiento a corto y largo plazo. Los resultados indican que los mercados de ovino se encuentran bastante interrelacionados pudiéndose... |

| Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in the Kazakh wheat sector, that is the extent and nature of integration among regional wheat markets. We applied threshold cointegration technique to assess the co-movement between time series of elevator prices at three grain-trading (and producing) spots in the northern and central parts of the country. Results suggest that markets of two northern grain trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with... |

| Reliable marketing opportunities in both interregional and international trade are an important precondition for further development of the agricultural sector. In this study we assess interregional integration of Kazakh wheat markets. We apply asymmetric threshold error correction models to assess the co-movement of elevator prices at three grain-trading spots in the northern and central parts of the country. Results suggest that markets of two northern grain-trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with Karaganda in central Kazakhstan is much weaker. Here, levelling out price gaps through arbitrage trade only occurs after a threshold of considerable extent has been surpassed. |
