Biography:

Dr Nan Jiang has a specialized research area in applied microeconomic analysis evolving around two themes. The first is the use of advanced econometric techniques in the evaluation of productivity and efficiency performance. Her PhD research explores dairy farming efficiency in NZ and has been published in the Journal of Productivity Analysis. Her second research theme focuses on translating empirical economic research into practical policy tools through empowering large integrated administrative datasets such as the Integrated Data Infrastructure (IDI). This is evident in her publications for the development of economic models to disentangle demand for hospital services, to predict the risk of hospital readmissions and to identify children who are likely to be mistreated. Those models have been implemented in practice by the District Health Boards and Ministry of Social Development, as well as international client such as the US Allegheny County. More recently, by combing the two themes, she is developing research programs with a particular focus on the utilization of large administrative data in productivity and efficiency analysis. The sectors under investigation include hospital, tertiary education, and housing construction.
