Determinants of legislative turnover in Western Europe, 1945–2015

This article explains legislative turnover in eight West European legislatures over 152 general elections in the period 1945–2015. Turnover is measured as the rate of individual membership change in unicameral or lower chambers. It is the outcome of a legislative recruitment process with a supply and a demand side. Decisions made by contenders affect supply, while decisions made by parties and voters influence demand. Such decisions are shaped by four political and institutional factors: the institutional context of political careers, or structure of political career opportunities; political party characteristics; electoral swings; and electoral systems. Ten specific hypotheses are tested within this theoretical framework. The structure of political career opportunities is the most decisive factor explaining variability in turnover rates, followed by electoral swings and political parties. Electoral systems show less substantive effects. Electoral volatility is the predictor with the most substantive effects, followed by duration of legislative term, strength of bicameralism, regional authority, gender quotas, level of legislative income and district magnitude.     

The Dynamics of State Policy Liberalism, 1936–2014

Applying a dynamic latent‐variable model to data on 148 policies collected over eight decades (1936–2014), we produce the first yearly measure of the policy liberalism of U.S. states. Our dynamic measure of state policy liberalism marks an important advance over existing measures, almost all of which are purely cross‐sectional and thus cannot be used to study policy change. We find that, in the aggregate, the policy liberalism of U.S. states steadily increased between the 1930s and 1970s and then largely plateaued. The policy liberalism of most states has remained stable in relative terms, though several states have shifted considerably over time. We also find surprisingly little evidence of multidimensionality in state policy outputs. Our new estimates of state policy liberalism have broad application to the study of political development, representation, accountability, and other important issues in political science.     

Referendums on Membership and European Integration 1972–2015

There are many myths about referendums. The most common one is that voters are inherently sceptical and tend to vote no when given the opportunity. This article analyses some of the commonly held ‘truths’ about referendums on EU matters. Based on a statistical analysis of all forty‐three EU‐related referendums since 1972, it shows that governments tend to lose referendums if they have been in office for a long time, that emotive words on the ballot paper are correlated with a high yes vote and that a high turnout is correlated with a vote against European integration, but campaign spending is inconsequential. Based solely on statistical evidence from the previous forty‐three referendums, the opponents of EU membership will win the Brexit referendum.     

The Commons Select Committee System in the 2015–20 Parliament

The House of Commons select committees witnessed some of the most constructive political theatre of the 2010‐2015 Parliament. Recall Rupert Murdoch's public contrition, Margaret Hodge's assault on MNC tax evasion and Keith Vaz's timely interrogations of G4S, etc. The committees also embraced social media and adopted public engagement as a key task. These developments all reflect a newly emboldened system. In recent months, four reports have been published which reflect on these developments. They also look forward to the further substantial development of committee activity. The system thus sets sail with an abundance of specific suggestions, including ideas that could have far wider and more far‐reaching democratic implications.     

The politics of government reorganizations: Evidence from 30 OECD countries, 1980–2014

Revisiting the seminal study of March and Olson (1983), this article aimed to empirically test whether or not government reorganizations at the ministerial level can be better explained by political factors than administrative and functional rhetoric. Government reorganizations have often been understood as functional adaptations to increase organizational efficiency and effectiveness, but little empirical research has been conducted on their political context. By analyzing pooled‐time series data from 30 OECD countries from 1980–2014 taken from the Statesman's Yearbook, this article sought to examine whether changes in political power are associated with government reorganizations and whether their intensity is affected by the country's political system (parliamentarism or presidentialism), transitions of administrative power, and political cycles of the top executive's tenure. The results suggested that government reorganizations are more likely to occur in parliamentary systems, after transitions of political power, and at the beginning of the top executive's tenure.
