Consumer behavior analysis is a fundamental issue in economics. The most prominent methodology that economists use to attribute preferences according to this principle is the revealed preference concept. Therefore, neoclassical utility function is capable to test the rational behavior hypothesis of consumer.
In this paper, we formalize a method of revealed preferences in place of neoclassical utility function to test the hypothesis of rational behavior using the Iranian rural households’ consumption data over the period 1982-2005. According to results, we didn't detect any violations in the whole consumption data. But in agriculture commodities group, we detected 4 violations using generalized Afriat index ascribed to measurement error. overall, the findings of the study confirm the hypothesis of rational behavior. Thus, there exists a utility function that is non-satiated, continuous, monotonic, and concave that rationalizes the consumption data of rural households in Iran
Keywords: Generalized Axiom of Revealed Preference, Neoclassical Utility Function, Afriat Theorem, Generalized Afriat Index
