Candidate: ________________________ Yuan Mu Abstract This thesis studies the Chinese banks’ credit risk assessment using the Post Keynesian approach. We argue that bank loans are the major financial sources in emerging economies and it is uncertainty, an unquantifiable risk, rather than asymmetric information about quantifiable risk, as held by the mainstream approach, which is most important for the risk attached to credit loans, and this uncertainty is particularly important in China. With the universal existence of uncertainty, borrowers and lenders have to make decisions based on convention and experience. With regard to the nature of decision-making, this implies the importance of qualitative methods rather than quantitative methods. The current striking problem in Chinese banking is the large amount of Non- Performing Loans (NPLs) and this research aims to address the NPLs through improving credit risk management. Rather than the previous literature where Western models are introduced into China directly or with minor modification, this work advocates building on China’s conventional domestic methods to deal with uncertainty. We briefly review the background of the Chinese banking history with an evolutionary view and examine Chinese conventions in the development of the credit market. Based on an overview of this history, it is argued that Soft Budget Constraints (SBC) and the underdeveloped risk-assessing mechanism contributed to the accumulation of NPLs. Informed by Western models and experience, we have made several suggestions about rebuilding the Chinese convention of credit risk assessment, based on an analysis of publications and interviews with Chinese bankers. We also suggest some further development of the Asset Management Companies (AMCs) which are used to dispose of the NPLs. i Acknowledgements I owe a great debt to Professor Sheila Dow, who supervised the thesis. Under her encouraging guidance and questioning, the ideas presented here have taken form. During the process I have grown to appreciate her as not only as intellectual mentor, but also as friend. If I could have used my time more wisely, I could learn more from her. I am also indebted to Dr. Dipak Ghosh for co-supervising this thesis. I particularly thank him for all his invaluable suggestions, feedbacks, critical reflections, and his support and patience in helping me in the areas of transition economy and financial derivatives. I am grateful to the members of the Economics Department of Stirling University for their encouragement and friendship; in particular I would like to thank my colleague Kobil Ruziev and Toshtemir Majidov for their friendship and offering me suggestions. My deepest thanks go to my beloved wife, Xiaowei Zhou, who sacrificed most. She has encouraged me to fulfil my ambitions and has supported me during three difficult years travelling between Stirling and Beijing. Most of her income from par- time work was spent on the flight tickets. ii Table of Contents Page Abstract i Acknowledgement ii Table of Contents iii List of Tables vii List of Figures viii List of
