Determining market power exertion between buyers and sellers: are nonparametrics a viable alternative?
A review of recent literature reveals the development of several deterministic non-parametric (DNP) tests of market power. The performance of selected DNP market power tests is ascertained to determine their usefulness as an alternative to data-hungry parametric market power tests. This assessment is carried out through implementation of Monte Carlo experiments using data sets from ten known market structures. Only two of the six DNP tests appear able to satisfactorily identify market power.
