Schritt für Schritt
(2008)
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.
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.
This article analyses salient trade-offs in the design of democracy. It grounds this analysis in a distinction between two basic models of democracy: simple and complex majoritarianism. These models differ not only in their electoral and party systems, but also in the style of coalition-building. Simple majoritarianism concentrates executive power in a single majority party; complex majoritarianism envisions the formation of shifting, issue-specific coalitions among multiple parties whose programs differ across multiple conflict dimensions. The latter pattern of coalition formation is very difficult to create and sustain under pure parliamentary government. A separation of powers between executive and legislature can facilitate such a pattern, while also achieving central goals of simple majoritarianism: identifiable cabinet alternatives before the election and stable cabinets afterward. The separation of powers can thus balance simple and complex majoritarianism in ways that are unavailable under parliamentarism. The article also compares the presidential and semi-parliamentary versions of the separation of powers. It argues that the latter has important advantages, e.g., when it comes to resolving inter-branch deadlock, as it avoids the concentration of executive power in a single human being.
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.
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. The book 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 6 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; it systematically compares the semi-parliamentary and presidential separation of powers; and it develops new and innovative semi-parliamentary designs, some of which do not require two separate chambers.
Review article: Democratic inclusiveness : a reinterpretation of Lijphart's patterns of democracy
(2010)
This contribution to the study or democratic inclusiveness advances three main claims, based on Lijphart's original data First, his measurement of executive inclusiveness is incoherent and invalid. Secondly, executive inclusiveness is best explained by the interaction of many parties and strong legislative veto points. This implies that executive inclusiveness should not be contained in either of Lijphart's two dimensions of democracy. Thirdly, parties have incentives to economize on the costs of inclusive coalitions by avoiding strong legislative veto points, and these incentives are greater in parliamentary than in presidential systems. Hence. Lijphart's favourite version of consensus democracy - characterized by a parliamentary system and a high degree of executive inclusiveness - is unlikely to be a behavioural-institutional equilibrium.
Political scientists regularly justify particular democratic institutions. This article explores two desiderata for such justifications. The first is a formal equality baseline which puts the burden of justification on those who favour more unequal institutions. This baseline is seen as an implication of the rule of law. The second desideratum, the comparison requirement, builds on the first: adequate justifications of particular institutions must compare them to the best alternative, and this comparison must consider the costs for political equality. The two desiderata are applied to political science debates about the proportionality of the electoral system and bicameral systems of legislative decision-making.
The project of public-reason liberalism faces a basic problem: publicly justified principles are typically too abstract and vague to be directly applied to practical political disputes, whereas applicable specifications of these principles are not uniquely publicly justified. One solution could be a legislative procedure that selects one member from the eligible set of inconclusively justified proposals. Yet if liberal principles are too vague to select sufficiently specific legislative proposals, can they, nevertheless, select specific legislative procedures? Based on the work of Gerald Gaus, this article argues that the only candidate for a conclusively justified decision procedure is a majoritarian or otherwise 'neutral' democracy. If the justification of democracy requires an equality baseline in the design of political regimes and if justifications for departure from this baseline are subject to reasonable disagreement, a majoritarian design is justified by default. Gaus's own preference for super-majoritarian procedures is based on disputable specifications of justified liberal principles. These procedures can only be defended as a sectarian preference if the equality baseline is rejected, but then it is not clear how the set of justifiable political regimes can be restricted to full democracies.
The article analyses a certain type of bicameralism not merely as a form of legislative organisation, but as a form of government-as a hybrid between parliamentarism and presidentialism. A new typology of pure and hybrid forms of government is proposed, which classifies bicameralism in Australia and Japan as chamber-independent government. This type is systematically compared with other forms of government, including hybrids like semi-presidentialism, elected prime-ministerial government in Israel (from 1996 to 2002) and assembly-independent government in Switzerland. The article highlights how chamber-independent government has the potential to combine different visions of democracy without leading to presidentialisation of political parties.
