Sensitivity Analysis Between Lagrange Multipliers and Consumer Coupon: Utility Maximization Perspective

Abstract

Sensitivity analysis is a vital concept in optimization models. From this analysis an economist can predict on the outcome of an economic model by the use of certain range of input variables. Utility maximization policy is essential for the sustainability of the economic organizations. This study takes an attempt to discuss sensitivity analysis between Lagrange multipliers and consumer coupon, where utility maximization is analyzed with detail mathematical analysis. In the study method of Lagrange multipliers is used to investigate the utility function; subject to two constraints: budget constraint, and coupon constraint. Moreover, two Lagrange multipliers are used here with four commodity variables.
