This study analyzes the spatial integration of exporting markets of raw honey in Brazil, taking into account the presence of transaction costs, since such costs may generate asymmetries in the relationships of prices among the markets under analysis. In order to achieve this goal, the analytical method of threshold cointegration by means of the estimation of the TAR and M-TAR models was used. The data were obtained in the Ministry of Development, Industry and Foreign Commerce for the period from January 2002 to July 2011. The results indicate the presence of asymmetries in the transmission of the price established in the central market, represented by Rio Grande do Sul, and the other states under consideration. In addition, negative and low magnitude shocks were excluded differently from the positive shocks. Therefore, one may conclude that the transaction costs influence the spatial interaction among the markets.
