From AD-AS to Advanced Macroeconomics
The chapter reviews basic building blocks of macroeconomic theory, such as the production function, labour supply and demand. It also reviews elementary models such the IS-LM, AD-AS, and the Phillips Curve. In doing so, it provides a bridge between standard elementary/intermediate material, that readers of this book will have typically been exposed to, and the more advanced macroeconomics that is its main subject. Alongside analytics, the chapter outlines the history of macroeconomics as a way of better appreciating the models and current theory. The policy implications of various theories and models are centrepieces. A brief detour into formal theory of policy-making offers additional policy perspectives. The chapter also summarizes six benchmark ‘policy ineffectiveness propositions’ developed in subsequent chapters, as a way of looking ahead.
