Modelling Regular and Estimable Inverse Demand Systems: a Distance Function Approach
journal contributionposted on 2017-11-03, 00:15 authored by Won, Gary K.K., McLaren, Keith R.
To be useful for realistic policy simulation in an environment of rapid structural change, inverse demand systems must remain regular over substantial variations in quantities. The distance function is a convenient vehicle for generating such systems. While it directly yields Hicksian inverse demand functions, those functions will not usually have an explicit representation in terms of the observable variables. Note however that this problem need not hinder estimation and could be solved by using the numerical inversion estimation approach. This paper develops the formal theory for using distance functions in this context, and demonstrates the operational feasibility of the method.
