The objectives of this research are to investigate the influence of geographical distance on the cointegration relationship in order to increase knowledge on the issue, and to indentify its role in Brazilian agricultural markets. With this intention, the cointegration framework is applied allowing for the presence of multiple structural breaks in the long run equation. The inclusion of breaks is in response to the multiple changes of the agricultural system during the period of investigation. The spatial integration is calculated between each market pair. The cointegration coefficient and geographical distance relationship is calculated by means of an OLS regression, taking into account the quality of roads and the proximity to a border or port. The effect...

The research analyzes the price transmission among the Costa Rican markets of cattle, beef and milk, accounting for asymmetric behavior and structural breaks. Monthly price data covering the first month of 1998 to the fourth month of 2008 were used. Price transmission between each market pair was found. The Price adjustment is consistent at 1% of significant with the behaviour expected. Cattle prices adjust in the milk - cattle relationship, beef meat prices adjust in the cattle - beef meat relation and in the milk - beef meat relation. This finding supports the statement regarding the leading position of “Dos Pinos” as the main player in the market. The results of the asymmetric analysis are not as expected. The coefficients of both adjustments (positive...

The price transmission between markets is often interpreted as providing insights into the market’s infrastructure efficiency and transaction costs. Thus, finding a possible explanation for the degree of integration has become an issue of special interest. Recent researchers have pointed out the distance between markets as one of the possible factors. However, the distance is closely related with other elements, such as road quality and the proximity to an export point, which affect transport costs, opportunity costs and thus the integration. Therefore, what the most important factor is when determining the relationship among markets remains unclear. The cointegration framework, OLS and principal component regressions are applied in order to investigate...
