At its heart, economics is the science of choice and a study of economic principles allows us to achieve a more informed understanding of how we make our choices; whether these choices occur in our everyday life, our work environment, or at the national or international level.

Volume two, Policies and Perspectives, delivers clear statements of essential economic principles, supported by real-world examples and uncluttered by extraneous material; the goal is to provide a concise readable primer that covers the substance of macroeconomic theory and policy. The text uses a single unifying tool-aggregate demand and aggregate supply analysis-to probe differing perspectives on macroeconomic policies. The text looks at fiscal policy and short-run stabilization; the financial sector and monetary policy; the international sector; and the sources of economic growth.
