Biography

Fang Xu obtained the degree of Doctor Scientiarum Politicarum in quantitative economics from Christian-Albrechts-University Kiel in 2008 and has the Master of Arts in Economics and Management Science from Humboldt-University Berlin. Her Bachelor degree of Economics is awarded by Nankai-Unviersity in China. After her graduate studies she has launched the project, “Theoretical and empirical studies of global current account imbalances”, funded by the Fritz-Thyssen Stiftung.
Her research interest during doctoral studies comprised econometric methods concerned with panel data modeling and hypothesis testing, and empirical analyses on topics in international macroeconomics. Precisely a new bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models is introduced.
A new semi-parametric approach for analysing determinants of the saving-investment relation, which is motivated by the Feldstein-Horioka puzzle, has been developed and applied. Moreover, the limited support of the time series of current account imbalances to GDP has been considered in unit root tests.
The results of her studies have been published (or are accepted for publication) in journals such as Computational Statistics & Data Analysis, Journal of International Money and Finance, The ManchesterSchool, and Applied Economic Letters.
Currently she is following two lines of research. The augmented Dickey-Fuller test for a unit root in bounded time series shall be derived and investigated. As the second line, an economic model will be considered to explain the influence of the openness to trade on the current account, which has been empirically investigated in her latest research.
