Parliamentary and presidential governments--exemplified by most European countries for the former and the United States and Latin America for the latter--are the two principal forms of democracy in the modern world. Their respective advantages and disadvantages have been long debated, at first mainly by British and American political observers but with increasing frequency in other parts of the world, not only in the Soviet Union and Eastern Europe, but in Latin America and Asia as well. The recent world-wide wave of democratization has intensified both the debate and its significance. This volume brings together the most important statement on the subject by advocates and analysts--from Montesquieu and Madison to Lipset and Linz. It also treats the merits of less frequently used democratic types, such as French-style semi-presidentialism, that may be regarded as intermediate forms between parliamentarism and presidentialism.

In a democracy, a constitutional separation of powers between the executive and the assembly may be desirable, but the constitutional concentration of executive power in a single human being is not. Beyond Presidentialism and Parliamentarism defends this thesis and explores 'semi-parliamentary government' as an alternative to presidential government. Semi-parliamentarism avoids power concentration in one person by shifting the separation of powers into the democratic assembly. The executive becomes fused with only one part of the assembly, even though the other part has at least equal democratic legitimacy and robust veto power on ordinary legislation. The book identifies the Australian Commonwealth and Japan as well as the Australian states of New South Wales, South Australia, Tasmania, Victoria, and Western Australia as semi-parliamentary systems. Using data from 23 countries and six Australian states, it maps how parliamentary and semi-parliamentary systems balance competing visions of democracy; it analyzes patterns of electoral and party systems, cabinet formation, legislative coalition-building, and constitutional reforms; systematically compares the semi-parliamentary and presidential separation of powers; and develops new and innovative semi-parliamentary designs, some of which do not require two separate chambers.

This book questions the reasons why presidential democracies more likely to break down than parliamentary ones.

Proposals for power-sharing constitutions remain controversial, as highlighted by current debates in Iraq, Afghanistan, Nepal, and Sudan. This book updates and refines the theory of consociationalism, taking account of the flood of contemporary innovations in power-sharing institutions that have occurred worldwide. The book classifies and compares four types of political institutions: the electoral system, parliamentary or presidential executives, unitary or federal states, and the structure and independence of the mass media. The study tests the potential advantages and disadvantages of each of these institutions for democratic governance. Cross-national time-series data concerning trends in democracy are analyzed for all countries worldwide since the early 1970s. Chapters are enriched by comparing detailed case studies. The mixed-method research design illuminates the underlying causal mechanisms by examining historical developments and processes of institutional change within particular nations and regions. The conclusion draws together the results and the practical lessons for policymakers.

In recent years renewed attention has been directed to the importance of the role of institutional design in democratic politics. Particular interest has concerned constitutional design and the relative merits of parliamentary versus presidential systems. In this book, the authors systematically assess the strengths and weaknesses of various forms of presidential systems, drawing on recent developments in the theoretical literature about institutional design and electoral rules. They develop a typology of democratic regimes structured around the separation of powers principle, including two hybrid forms, the premier-presidential and president-parliamentary systems, and they evaluate a number of alternative ways of balancing powers between the branches within these basic frameworks. They also demonstrate that electoral rules are critically important in determining how political authority is exercised.
