Table 5. Results of the consumer choice model

Results show that the income status of consumers considerably determines purchasing
frequency for organic and integrated fruit and vegetable. As has been expected, purchasing
frequency significantly increases with higher household disposable incomes; however the
estimated marginal effects reveal non-linear patterns for this variable. A high quasi-
elasticity coefficient for non-buyers (Y=0) ranking to 0.66 suggests that low income level
very likely determines no purchasing of organic and integrated fruit and vegetables. Also
