Professor Petra Schleiter

BSc Lond, MA MPhil DPhil Oxf


After completing her undergraduate degree (BSc in International Relations) at the London School of Economics, Professor Schleiter did her graduate work at the University of Oxford, including an MPhil in Russian Studies (St Antony's College), and a DPhil in Politics (Nuffield College).

Professor Schleiter's focuses on the consequences of comparative political institutions. She has developed a strong research profile in this area with work that explores the effects of semi-presidentialism, presidentialism, party systems, fixed parliamentary terms and flexible election timing, caretaker conventions and recognition rules on a variety of political outcomes. Of particular interest to her are the implications of these institutions for governmental corruption, democratic survival, cabinet formation and termination, electoral accountability and policy diffusion. Her work has been published in leading journals in the discipline including the American Political Science Review, Journal of Politics, Comparative Political Studies, the British Journal of Political Science, Party Politics, European Journal of Political Research, Parliamentary Affairs and elsewhere.

Professor Schleiter's work is motivated by research questions that are of scientific and practical importance. It focuses on the consequences of comparative political institutions and its contributions span five major areas, which she describes as follows:

(1) Executive presidents, cabinet composition, regime stability and electoral accountability

Many European and Latin American political systems feature executive presidents who have some influence on cabinet composition, policy and – in the case of Europe – election calling. Mys research makes contributions to the understanding of presidential influence on cabinet composition, regime stability and electoral accountability. Turning first to cabinet composition, presidents frequently appoint ministers who lack party affiliation. Such appointment strategies have puzzled researchers for some time and are often assumed to indicate a president’s intention to circumvent parliament, which is expected to undermine democratic stability. My work contributes to a better understanding of presidential cabinet formation strategies. It clarifies that the distinct electoral mandates of presidents and assemblies often cause a president’s political goals to diverge from those of their party. In such circumstances non-party ministers can be better agents for presidents than co-partisans. Turning to regime stability, I find that non-party appointments on their own do not signal authoritarian intentions and a president’s unwillingness to work with the legislature. These results contribute to a more nuanced understanding of why democracies with executive presidents are typically more stable than predicted. In examining the impact of presidents on electoral accountability, my work has focused on the powers of European presidents to influence assembly dissolution and exert leverage in the electoral arena. Presidents with significant dissolution powers, I find, enable their political allies in government to face the electorate under systematically more favourable conditions than their peers who lack presidential support, which can have a transformative impact on a government’s electoral success.

(2) Party system features, accountability, governmental corruption and policy diffusion

Party system features affect the attribution of responsibility for political choices and how easy it is to hold incumbents to account, which has consequences for outcomes ranging from governmental corruption to policy diffusion. My work makes contributions in understanding both outcomes. Governmental corruption persists in many democracies around the world, even though surveys indicate that voters disapprove of it. Party system features, I show in work with Alisa Voznaya, are an important key to this puzzle. Party systems that are poorly institutionalized, non-programmatic, dominated by a single party, or fragmented, reduce the ability of voters to select non-corrupt representatives and to punish those who permit malfeasance. This widens the scope for governmental corruption. Party system features also shape cross-national policy diffusion. It is well established that political parties learn from the policy positions of successful incumbents abroad. But among that group of incumbents some parties are more influential than others. In a paper with Thomas Bӧhmelt, Lawrence Ezrow and others, I show that the policies of sole or dominant incumbent parties are more visible to foreign party strategists and more readily adopted by parties abroad. This suggests that party systems, which concentrate power within government, give rise to incumbents with greater cross-national policy influence.

(3) Election timing powers, government terminations and the heterogeneity of early elections

A major constitutional distinction separates parliamentary democracies in which governments have discretion to time elections from those in which governments have no such powers. This distinction has far-reaching implications for parliamentary bargaining about a broad range of outcomes. My work makes a series of contributions in charting these powers and their effect on the management of government terminations by politicians. I develop an original index to measure assembly dissolution powers in parliamentary democracies (with Max Goplerud). My article in the American Political Science Review (with Edward Morgan-Jones) demonstrates the importance these powers in shaping government survival. In related work, I note that these powers generate heterogeneity among early elections because they can either be used by the government to seize favourable circumstances and consolidate its position, or directed against the government when its hold on power slips. By showing that these two types of elections are distinct political outcomes that require separate explanations, my work recasts the dependent variable in the literature on government terminations. Using this distinction, I explore how governments’ powers to time elections condition their responses to risks and opportunities generated by the economy and in other policy areas. I am currently completing a book on this topic.

(4) Opportunistic election timing, electoral accountability and voter reactions

Whether and how flexible election timing yields electoral benefits for governments is not well understood. Yet, this is a question with important normative implications for policy debates: Governmental election timing powers are contentious precisely because they are believed to give incumbents an unfair electoral advantage. My research provides the first examination of that advantage and breaks new ground in the scholarly and political debates: In a paper with Margit Tavits, I provide the first systematic cross-national comparative analysis of incumbency bonuses from opportunistic election timing and demonstrates that prime ministers are able to realize an average vote share advantage of up to 5 per cent when they have discretion to call elections. In a related paper we employ a survey experiment to test the causal mechanisms behind this phenomenon and shows that voters’ inclination to reward the good policy performance that triggers strategic election calls is not overwhelmed by their desire to punish incumbent opportunism. These findings are corroborated by case studies of election timing choices and outcomes.

(5) Government termination, formation and election calling in the UK

Linked to my work on topics 3 and 4 is an impact-focused research agenda, in which I address the effects of (i) the recent change in the discretion of UK governments to time elections (the Fixed-term Parliaments Act, 2011), (ii) the UK’s caretaker conventions, which govern the period between an election or the resignation of a cabinet and the formation of a new government, and (iii) the UK’s recognition rules, which guide the selection of a new prime minister in a hung parliament (much of this work with Valerie Belu). In each of these areas, my work analyses the UK’s constitutional rules in comparative European perspective and charts a new dimension in the UK policy and public debates. This work has generated an edited collection and a series of articles that have had considerable policy impact.
