This book, by one of China's leading economists, explores the past and present of the RMB—the people's currency—as it is poised to compete with the dollar as the international reserve currency. Exchange rate movement and its pass-through to changes in domestic prices have been topics of wide concern among economists. However, relatively few studies have empirically investigated the relationship between exchange rate movements and China's international trade.This book fills this gap, using the general equilibrium theory of the western economic science norm systems, integrating the leading heterogeneous firm theory of international trade, attempting to set up a theoretical structural model for further prediction, and applying the data from sample cases to examine the structural model. This book will be of interest to economists, financiers, and China watchers.
