Numerical simulations of techniques related to utility function and price elasticity estimators

In many economic models the utility function chosen is based on preconceived ideas of the economic state. In order for a utility function to be fit to raw demand data an assumption is made (amongst others) that a preference relation holds within a cycle of data points (Eberhard et al. (2009)). In this paper we assume that errors have occurred in the data collection process which have somewhat corrupted the quantity consumed for the particular commodity price. This results in inconsistences in the preference relation and infeasibility of Afriat inequalities (Eberhard et al. (2009).
