This book was awful. Did a terrible job explaining a thing. It leaves me with way more questions and a hell of a lot of confusion... No answers to be had from this
I road the seventh edition of it translated in Arabic, i found it so useful, easy explanation of a lot of things about Macroeconomic and Economy science as whole.
