RT Report T1 Theory and Application of an Economic Performance Measure of Risk A1 Niu, Cuizhen A1 Guo, Xu A1 McAleer, Michael A1 Wong, Wing-Keung AB Homm and Pigorsch (2012a) use the Aumann and Serrano index to develop a new economic performance measure (EPM), which is well known to have advantages over other measures. In this paper, we extend the theory by constructing a one-sample confidence interval of EPM, and construct confidence intervals for the difference of EPMs for two independent samples. We also derive the asymptotic distribution for EPM and for the difference of two EPMs when the samples are independent. We conduct simulations to show the proposed theory performs well for one and two independent samples. The simulations show that the proposed approach is robust in the dependent case. The theory developed is used to construct both onesample and two-sample confidence intervals of EPMs for Singapore and USA stock indices. PB Facultad de Ciencias Económicas y Empresariales.
