This unique book makes a contribution to the deeper understanding of various trade-related investment measures (TRIMs). The issues have been largely inspired by the use of trade policies on foreign investment adopted in China and many other nations from the 1960s to the 1990s. Building upon the existing literature and the authors' own work, the 20 chapters in the book examine, using several versions of general-equilibrium frameworks, resource allocation and welfare effects of both trade-related investment measures and investment-related trade/environmental measures. Traditional and duality microeconomic tools and modelling techniques have been extensively utilised in analysing various real-world, investment and environmental issues, especially those encountered in developing economies. Policy implications regarding optimal trade, investment and environmental policies that emerged from the analyses are also provided.This book is self-contained in applications of trade theories and related general-equilibrium modelling techniques. It may be used as an advanced textbook in trade theory and policy as well as a reference book for policy makers, professional practitioners and academic researchers in designing trade policies.
