Teach students to apply macroeconomics as Gwartney/Stroup/Sobel/Macphersons MACROECONOMICS: PRIVATE AND PUBLIC CHOICE, 17E places more emphasis than other text of its kind on the role of entrepreneurship in a market economy and the importance of public choice analysis in understanding the political process. New content shows entrepreneurship as key to understanding how the competitive market uses innovations to improve living standards. The authors also demonstrate how public choice analysis helps clarify voter, politician and bureaucrat incentives and their impact on political outcomes – which is particularly important since about 40 percent of national income is allocated through politics. Introductory chapters cover basic economic thinking while stressing how incentives influence individual choices under constraints imposed by scarcity and while highlighting how government attempts to alter incentives often create secondary effects. Content also shows how wealth is created as the "invisible hand" of market prices coordinates exchanges between consumers and producer-entrepreneurs.
