Abstract: This paper is a review of consumer behaviour with respect to linear expenditure system, separable and additive utility functions, homogeneous and homothetic utility functions, direct and indirect utility functions and duality in consumption. Consumers of economic commodities are believed to be rational (always seeking to maximize utility and minimize cost). This theory of consumer behavior is useful in the analysis of utility optimization. The specific properties of utility functions are of interest to the economist. Linear expenditure systems are helpful in developing theories that are conformable to empirical modeling and estimation. Separable and additive utility functions emphasize that utility is derived from a group of commodities. Homothetic function is a monotonic transformation of a homogeneous function. The concept of’ ‘Duality’ enables analysis of direct and indirect utility functions based on convenience. We are able to derive the compensated demand function using the duality principle.
