Reynolds brings together the leading scholars to discuss the successes and failures of constitutional design. Arend Lijphart and Donald Horowitz debate their own contributions to the field. Emerging scholars then present important new evidence from Europe, the CIS, Latin America, and Africa. Chapters analyse the effect of presidential and parliamentary systems, issues of federalism and autonomy, and the varying impact of electoral systems. The book concludes with case studies of Fiji, Ireland, Eritrea, Indonesia, Nigeria, and India. The Architecture of Democracy is the culmination of the study of constitutional engineering in the third wave of democracy and sets parameters for this crucial research as democracy diffuses across the world.
