      abstract = {This article seeks to analyze the demand’s sensibility for  organic food and their conventional counterparts to  variations in prices and expenditure in Brazilian  households. We estimated an aggregate demand system for 14  categories (seven organics and seven conventional) using  the QUAIDS model with correction for the Zero Consumption  Problem by the Shonkwiller and Yen twostep estimation  method. The database was from the microdata from the  Brazilian Household Budget Survey (POF/IBGE) 2008/2009.  Results showed that Brazilian consumers are more sensitive  to variations in prices and expenditure of organic than  conventional food. Moreover, there is asymmetry in  substitution/complementarity relations between the two  types of food. These results suggest that it is relatively  difficult to induce consumers that are used to purchase  organic products to “revert” their spending habits changing  organic products to conventional ones. Furthermore, results  showed that consumers do not view organic food as a  substitute for conventional food in most cases. Examining  the expenditure elasticities, we conclude that organic  foods can be classified as luxury goods.},
