This book studies the causes and cures of inflation in a monetary union. It carefully discusses the effects of money growth and output growth on inflation. The focus is on producer inflation, currency depreciation and consumer inflation. For instance, what determines the rate of consumer inflation in Europe, and what in America? Moreover, what determines the rate of consumer inflation in Germany, and what in France? Further topics are real depreciation, nominal and real interest rates, the growth of nominal wages, the growth of producer real wages, and the growth of consumer real wages. Here productivity growth and labour growth play significant roles. Another important issue is target inflation and required money growth. A special feature of this book is the numerical estimation of shock and policy multipliers.
