This article responds to critical reflections on my Beyond Presidentialism and Parliamentarism by Sarah Birch, Kevin J. Elliott, Claudia Landwehr and James L. Wilson. It discusses how different types of representative democracy, especially different forms of government (presidential, parliamentary or hybrid), can be justified. It clarifies, among other things, the distinction between procedural and process equality, the strengths of semi-parliamentary government, the potential instability of constitutional designs, and the difference that theories can make in actual processes of constitutional reform.
Review symposium
(2023)
Steffen Ganghof’s Beyond Presidentialism and Parliamentarism: Democratic Design and the Separation of Powers (Oxford University Press, 2021) posits that “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” (Ganghof, 2021). To consider, examine and theorise about this, Ganghof urges engagement with semi-parliamentarism. As explained by Ganghof, legislative power is shared between two democratically legitimate sections of parliament in a semi-parliamentary system, but only one of those sections selects the government and can remove it in a no-confidence vote. Consequently, power is dispersed and not concentrated in the hands of any one person, which, Ganghof argues, can lead to an enhanced form of parliamentary democracy. In this book review symposium, George Tsebelis, Michael Thies, José Antonio Cheibub, Rosalind Dixon and Daniel Bogéa review Steffen Ganghof’s book and engage with the author about aspects of research design, case selection and theoretical argument. This symposium arose from an engaging and constructive discussion of the book at a seminar hosted by Texas A&M University in 2022. We thank Prof José Cheibub (Texas A&M) for organising that seminar and Dr Anna Fruhstorfer (University of Potsdam) for initiating this book review symposium.
Veto player theory is a powerful approach to comparative politics. This article argues that the debate about its explanatory success would benefit from more systematic distinctions. The theory not only comes in different theoretical variants, it is also used in radically different ways empirically. Starting from recent debates about the ‘testing’ of theoretical models, the article distinguishes five ways in which theoretical models can be used empirically: contrastive, axiomatic, exploratory, presumptive and modular. The typology is applied to veto player theory and illustrated with exemplary studies and debates. The article concludes that each type raises different questions that should be answered in individual studies. Moreover, while veto player theory has an excellent track record on four empirical uses, the picture on its contrastive use is far more nuanced. More explicitly contrastive testing of the theory is desirable.
Are potential cabinets more likely to form when they control institutional veto players such as symmetric second chambers or minority vetoes? Existing evidence for a causal effect of veto control has been weak. This article presents evidence for this effect on the basis of conditional and mixed logit analyses of government formations in 21 parliamentary and semi-presidential democracies between 1955 and 2012. It also shows that the size of the effect varies systematically across political-institutional contexts. The estimated causal effect was greater in countries that eventually abolished the relevant veto institutions. It is suggested that the incidence of constitutional reform is a proxy for context-specific factors that increased the incentives for veto control and simultaneously provided a stimulus for the weakening of institutional veto power.
The article responds to four commentaries on the concept of semi-parliamentary government and its application to Australian bicameralism. It highlights four main points: (1) Our preferred typology is not more ‘normative’ than existing approaches, but applies the criterion of ‘direct election’ equally to executive and legislature; (2) While the evolution of semi-parliamentary government had contingent elements, it plausibly also reflects the ‘equilibrium’ nature of certain institutional configurations; (3) The idea that a pure parliamentary system with pure proportional representation has absolute normative priority over ‘instrumentalist’ concerns about cabinet stability, identifiability and responsibility is questionable; and (4) The reforms we discuss may be unlikely to occur in Australia, but deserve consideration by scholars and institutional reformers in other democratic systems.
The article analyses the type of bicameralism we find in Australia as a distinct executive-legislative system – a hybrid between parliamentary and presidential government – which we call ‘semi-parliamentary government’. We argue that this hybrid presents an important and underappreciated alternative to pure parliamentary government as well as presidential forms of the power-separation, and that it can achieve a certain balance between competing models or visions of democracy. We specify theoretically how the semi-parliamentary separation of powers contributes to the balancing of democratic visions and propose a conceptual framework for comparing democratic visions. We use this framework to locate the Australian Commonwealth, all Australian states and 22 advanced democratic nation-states on a two-dimensional empirical map of democratic patterns for the period from 1995 to 2015.
A new political system model
(2018)
Semi-parliamentary government is a distinct executive-legislative system that mirrors semi-presidentialism. It exists when the legislature is divided into two equally legitimate parts, only one of which can dismiss the prime minister in a no-confidence vote. This system has distinct advantages over pure parliamentary and presidential systems: it establishes a branch-based separation of powers and can balance the ‘majoritarian’ and ‘proportional’ visions of democracy without concentrating executive power in a single individual. This article analyses bicameral versions of semi-parliamentary government in Australia and Japan, and compares empirical patterns of democracy in the Australian Commonwealth as well as New South Wales to 20 advanced parliamentary and semi-presidential systems. It discusses new semi-parliamentary designs, some of which do not require formal bicameralism, and pays special attention to semi-parliamentary options for democratising the European Union.
Arend Lijphart uses an average of five standardized variables – the executive-parties dimension (EPD) – to describe patterns of democracy and explain differences in democracies’ performance. The article suggests ways to improve the descriptive part of the project. It argues that the EPD maps different approaches to achieving accountability and representation, rather than differences in consensus. This re-conceptualization leads to a more coherent and valid measurement. It is also argued that more systematic adjustments are needed for differences in constitutional structures (presidentialism and bicameralism). The article presents data on a revised EPD and its components for 36 democracies in the period from 1981 to 2010. As to the explanatory part of the project, we contend that the EPD often hinders adequate causal analysis rather than facilitating it. We show this by re-analysing democracies’ performance with respect to turnout and capital punishment.
Die Fragmentierung europäischer Parteiensysteme und damit verbundene Schwierigkeiten bei der Koalitionsbildung haben zu einer Neuauflage altbekannter Debatten über unterschiedliche Wahlsysteme geführt. Einige Autoren sehen dabei bestimmte Wahlsysteme als optimalen Kompromiss zwischen den Prinzipien der Mehrheits- und der Verhältniswahl an. Wir argumentieren, dass diese Optimalitätsargumente eine konzeptionelle Schlagseite zugunsten „majoritärer“ Demokratiekonzeptionen haben. Eine anspruchsvolle „proportionale“ Demokratiekonzeption umfasst die Ziele mechanischer Proportionalität, multidimensionaler Repräsentation und wechselnder Gesetzgebungsmehrheiten. Diese Ziele lassen sich allerdings im parlamentarischen Regierungssystem nicht mit den Zielen der Mehrheitswahl vereinbaren. Der Grund ist, dass die relevanten Hürden des Wahlsystems gleichzeitig für die parlamentarische Repräsentation und die Teilnahme am Misstrauensvotum gelten. Erstere ist entscheidend für die proportionale, letztere für die majoritäre Konzeption der Demokratie. Sind wir bereit diese beiden Hürden zu entkoppeln – und somit das Regierungssystem zu verändern – ergibt sich eine Vielfalt neuer Reformoptionen. Wir illustrieren diese Punkte mit Daten für 29 demokratische Systeme im Zeitraum von 1995 bis 2015.
A comprehensive typology of basic executive formats is presented and linked to a discussion of tradeoffs in the design of executive-legislative relations. The focus is on the tradeoffs between three goals: (1) programmatic parties, (2) identifiable cabinets and (3) issue -specific legislative coalitions. To include semi-presidentialism into the typology in a logically consistent manner, a heretofore neglected executive format has to be defined, which is labelled semi-parliamentarism. Based on a discussion of Australian states, it is argued that semi-parliamentarism has the potential to mitigate the trilemma.
