Abstract
In this paper, QUAIDS analysis was carried out to examine the demand system of vegetables in the Philippines, with casting light on the endogenous issues for a more rigorous discussion. As a result of comparing the model controlling for the endogeneity and the model without controlling for the endogeneity, the percent difference between elasticities of two models was shown up to 187%. This result suggests that price and expenditure endogeneities have a significant influence on estimates in the demand system, and the result implies that this may lead to inconsistent estimates when demand analysis does not control for endogeneity.
