Owing to the fact that monetary economics is very controversial, most economists, however, agree that this concept money , around which the title of this book revolves, plays a paramount role in the process of development in developed, emerging and developing economies. Monetary economists are in concord that money supply determination is a portfolio framework. However, they are in disagreement about what determines interest rates and inflation. This book will be of immense importance to both undergraduate and postgraduate students who want to understand these three monetary concepts from broad perspective and popular views. It will in fact be very useful to students who do not know how to make econometric models and how to analytically interpret results from estimated parameters.
