The authors begin from a premise that political leaders are self-interested politicians rather than benign agents of the people they lead. When leaders depend on only a few backers to stay in power, they dole out privileges to those people, thereby dissipating their country's total resources and national growth potential. On the other hand, leaders who need large coalitions to stay in office implement policies that generally foster growth and political competition over ideas. The result is that those who promote policies that lead to stagnation tend to stay in office for a long time, and those who produce prosperity tend to lose their jobs. Analyzing countries in North and South America and Asia, the authors discuss the range of political regimes that permit or even encourage leaders to rule by mismanaging their nation's resources. And they show that nations must forge institutions that allow all social groups to participate in and benefit from the economy as well as force political leaders to be responsible for policy outcomes.
