Is China’s Currency Substantially Undervalued? Duo QIN SOAS (School of Oriental and African Studies), University of London (collaborated with Xinhua HE) (based on two papers: see QM Discussions Papers 660 & 667)
YES, from most of the existing studies Problems: data samples and methods differ
Our Approach • Choice of theoretical model: following the BEER (behavioral equilibrium exchange rate) principle • Data: quarterly time series for 1994-2009Q1, covering 70%+ trading partners with China (22 economies) • Econometrics: long-run cointegration; bilateral model estimation and also panel estimation
Basic Model (2 versions) Real exchange rate Ratio of real per capita GDP Ratio of per capita net foreign assets Ratio of CPI-PPI ratios Johansen cointegration Single equation long-run Two ways of estimation Panel (dynamic panel method): Assuming identical parameters of interest
REER Misalignments Another set for panel results
Misalignments as percentage of the trilateral-currency based REER
Main findings • REER of RMB is no longer undervalued since the onset of the current global recession • Misalignment still exist between RMB and the US$ and Euro, indicating the latter two being overvalued, especially versus the other currencies in the 22-economy basket
Post sample development • Euro depreciated over 10% during 2009Q4-2010Q2 (measured by SDR) • US$ depreciated over 5% 2010Q3 • In late September 2010, the US House of Representatives overwhelmingly passed a bill approving retaliatory import duties on Chinese goods because of China’s alleged manipulation of RMB
Has RMB misalignment been substantial to qualify for manipulation? • Any historical precedent? (as normally investigated from a legal perspective) • Similar cases: Japan of 1980s; West Germany (similar openness), Singapore (high current account surplus), Taiwan (rapid trade growth in 1980s) But different currency control systems (A subsequent study jointly with LIU Yimeng)
Model Approach • Panel estimation of long-run REER • Data: quarterly from late 1970s to 2000; 17 economies • Full panel versus sub-panel (only have US and Euroland)

Main findings • RMB undervalued misalignments are not unprecedented • The estimated long-run relations not distinctively different from that of RMB, irrespective of different currency control systems • The trilateral situation in RMB is most pronounced, implying overvalued euro & US$ • Some lessons to be learnt from the history
