Proportional versus winner-take-all electoral vote allocations

This paper considers how the welfare of voters is affected under an Electoral College system when some state elects to award electoral votes in proportion to the number of votes received by each candidate rather than awarding all electoral votes to the winner of the state. I show that a majority of voters in that state is made worse off as a result of the change. I also give conditions under which voters in other states are made better or worse off as a result of the change.     

Electoral Rewards for Personal Vote Cultivation under PR-STV

Generally the assumption is that legislators act to maximise their chances of re-election, with their optimal behaviour determined by the party-centred or candidate-centred nature of the electoral system in use. Existing evidence of the impact of members' actual behaviour on subsequent electoral performance is inconclusive. This research explores whether or not legislators who choose to focus on cultivating personal votes reap rewards from the electorate under the Single Transferable Vote (STV) electoral system. Exploring electoral reward under STV is particularly significant because some legislators face intra-party competition for votes while others do not – a key determining incentive for cultivating personal votes. This study uses a survey of Irish legislators in 2002 and 2007 to measure constituency orientation and effort. The data suggest an electoral reward for personal vote cultivation, although the relationship between intra-system incentive and reward is apparently not always as expected.     

An Opposing View of Scotland's Ballot Paper Problem: Arbuthnott and the Government had the Right Idea

The May 2007 Scottish Parliament election used a different ballot format from the one used in the previous elections, one that combined the regional and constituency votes onto one ballot paper (two separate papers were used before). Because there were many more invalid votes in 2007, the problem was blamed on the two‐vote ballot paper, which was recommended by the Arbuthnott Commission to prevent misunderstandings about what the two votes were for. Other places that use the mixed‐member proportional (MMP) electoral system tend to use a two‐vote ballot paper, with Germany and New Zealand seeing low levels of invalid votes. While the decision to revert to two separate papers in future Scottish Parliament elections might reduce the number of invalid votes, the price could be more confusion about the proportional nature of the electoral system unless public education improves significantly.     

Re-examining the evidence on the electoral impact of terrorist attacks: The Spanish election of 2004

This paper re-examines the electoral effect of the 11-M terrorist attacks in Madrid. Previous research has focused on post-electoral surveys to construct counterfactuals for the evaluation of the electoral impact of the attack. Bali (Electoral Studies, 2007) claims that the terrorists attacks had an important electoral impact while Lago and Montero (2005) claim the opposite. In this paper I propose to re-examine the evidence using a methodological approach based on actual votes instead of opinions revealed by surveys, and the difference-in-differences estimator. The calculations under the counterfactual of “no terrorist attack” support the forecasts of the polls taken prior to the terrorist attack and the results of Bali (2007). The incumbent (conservative) party would have won the election with between 42% and the 45% of the votes, while the socialist party would have obtained 37% of the votes.     

Personal vote‐seeking in flexible list systems: How electoral incentives shape Belgian MPs' bill initiation behaviour

It is well known that different types of electoral systems create different incentives to cultivate a personal vote and that there may be variation in intra‐party competition within an electoral system. This article demonstrates that flexible list systems – where voters can choose to cast a vote for the list as ordered by the party or express preference votes for candidates – create another type of variation in personal vote‐seeking incentives within the system. This variation arises because the flexibility of party‐in‐a‐district lists results from voters' actual inclination to use preference votes and the formal weight of preference votes in changing the original list order. Hypotheses are tested which are linked to this logic for the case of Belgium, where party‐in‐a‐district constituencies vary in their use of preference votes and the electoral reform of 2001 adds interesting institutional variation in the formal impact of preference votes on intra‐party seat allocation. Since formal rules grant Belgian MPs considerable leeway in terms of bill initiation, personal vote‐seeking strategies are inferred by examining the use of legislative activity as signalling tool in the period between 1999 and 2007. The results establish that personal vote‐seeking incentives vary with the extent to which voters use preference votes and that this variable interacts with the weight of preference votes as defined by institutional rules. In addition, the article confirms the effect of intra‐party competition on personal vote‐seeking incentives and illustrates that such incentives can underlie the initiation of private members bills in a European parliamentary system.     

Preference votes without preference? Institutional effects on preference voting: an experiment

A classical question of political science is to what extent electoral systems influence voting behaviour. Yet, many of these studies examine how different electoral systems affect the election results in terms of vote distribution across parties. Instead, we investigate how electoral rules affect intra party preference voting. Given the importance of the debate on the personalization of politics, insight into how electoral rules shape intra-party choice is a valuable contribution to the literature. In our study, we focus on the effect of two specific rules: the option to cast a list vote and on a single versus multiple preference votes. The results of experiments conducted in Belgium and the Netherlands show that electoral rules indeed influence voting behaviour with regard to intra party preference voting, although differences exist between the Netherlands and Belgium. Moreover, we find that the option to cast a list vote equally affects votes for the first candidate on the list, as well as lower positioned candidates. This suggests that preference votes might be less preferential than has often been assumed.     

The architecture of the Electoral College,the House size effect,and the referendum paradox

Using data from U.S. presidential elections, we show how seemingly insignificant changes to what we call the “architecture” of the Electoral College can cause different candidates to be elected President, even when no one changes how they vote. We consider varying the size of the House of Representatives, the method of apportionment, the number of “Senate” electoral votes cast by each state, and the lower bound on the number of “House” electoral votes cast by each state. We consider, in particular, elections with a “referendum paradox”. In these elections, the electoral vote winner is not the popular vote winner. Our work extends Neubauer and Zeitlin (2003) who analyzed the case of the 2000 election. We give an explanation for the effects that we observe in the data.     

When politics prevails: Parties,elections and loyalty in the European Parliament

In many political systems, legislators serve multiple principals who compete for their loyalty in legislative votes. This article explores the political conditions under which legislators choose between their competing principals in multilevel systems, with a focus on how election proximity shapes legislative behaviour across democratic arenas. Empirically, the effect of electoral cycles on national party delegations’ ‘collective disloyalty’ with their political groups in the European Parliament (EP) is analysed. It is argued that election proximity changes the time horizons, political incentives and risk perceptions of both delegations and their principals, ‘punctuating’ cost‐benefit calculations around defection as well as around controlling, sanctioning and accommodating. Under the shadow of elections, national delegations’ collective disloyalty with their transnational groups should, therefore, increase. Using a new dataset with roll‐call votes cast under legislative codecision by delegations between July 1999 and July 2014, the article shows that the proximity of planned national and European elections drives up disloyalty in the EP, particularly by delegations from member states with party‐centred electoral rules. The results also support a ‘politicisation’ effect: overall, delegations become more loyal over time, but the impact of election proximity as a driver of disloyalty is strongest in the latest parliament analysed (i.e., 2009–2014). Furthermore, disloyalty is more likely in votes on contested and salient legislation, and under conditions of Euroscepticism; by contrast, disloyalty is less likely in votes on codification files, when a delegation holds the rapporteurship and when the national party participates in government. The analysis sheds new light on electoral politics as a determinant of legislative choice under competing principals, and on the conditions under which politics ‘travels’ across democratic arenas in the European Union's multilevel polity.     

The house size effect and the referendum paradox in U.S. presidential elections

Barthélémy et al. (2014), extending the work of Neubauer and Zeitlin (2003), show that some U.S. presidential elections are subject to a ‘House size effect’ in that the winner of the election, i.e., the candidate who wins a majority of electoral votes, depends on the size of the House of Representatives. The conditions for the effect relate to the number of ‘Senate’ versus ‘House’ electoral votes won by each candidate, but the relationship is not straightforward due to ‘locally chaotic’ effects in the apportionment of House seats among the states as House size changes. Clearly a Presidential election that is subject to the House size effect exhibits the referendum paradox, i.e., the electoral vote winner is the popular vote loser, for some House sizes but not for others.     

Blind spots in the party system: Spatial voting and issue salience if voters face scarce choices

Drawing on spatial models of political competition, this research investigates whether decision weights vary across groups of voters defined by their policy positioning in a two-dimensional space. Our analyses of electoral survey data from England, France, Germany, the Netherlands and Switzerland reveal that the economic and cultural dimensions of electoral competition are salient for the vote choice of most groups of voters. However, those voters who hold economically right and culturally libertarian preferences weigh their preferences on the economic dimension more and discount parties’ position on cultural issues when no party represents their configuration of preferences. Consequently, left parties are less able to attain votes of economically right but culturally libertarian voters for cultural policy reasons, when electoral choices are scarce, while right parties are successful in attaining votes based on both dimensions. As a result, significant representation gaps can occur.     

Measuring party nationalisation: A new Gini-based indicator that corrects for the number of units

The study of the territorial distribution of votes in elections has become an important field of the political party research in recent years. Quantitative studies on the homogeneity of votes and turnout employ different indicators of territorial variance, but despite important progresses in measurement, many of them are sensitive to size and number of political parties or electoral districts. This article proposes a new ‘standardised party nationalisation score’, which is based on the Gini coefficient of inequalities in distribution. Different from previous indicators, the standardised party nationalisation score weights for the sizes of territorial units (such as electoral districts) within a country, and considers the different numbers of territorial units in different countries.     

Electoral registration and the control of votes: The case of Chile

We investigate how the employment relationship may lead employers to control the voting behavior and to induce the electoral registration of their workers. Forced registration and the control of votes become feasible when voting behavior is observable, as in open ballot elections. Workers whose vote is controlled are more likely to be registered as compared to other eligible voters, increasing their impact on electoral outcomes. Increasing the secrecy of the vote (for instance with the adoption of a secret ballot) significantly reduces the control of votes. Electoral registration, however, remains biased as long as the probability of voting behavior disclosure induces less ideologically motivated voters to comply with the political preference of the employer. We provide empirical support for the predictions of the model examining the effects of the introduction of the secret ballot in Chile in 1958.     

Electoral contexts that impede voter coordination

An electorate can effectively coordinate on the viable parties in its district, or a relatively large proportion of its voters may “waste” their votes on parties that fail to obtain office. Avoiding wasted votes can be more or less difficult depending on several characteristics of the electoral context. Unfortunately, many of the features of electoral contexts hypothesized to cause vote wastage have been tested piecemeal on only a handful of (non-random) cases and/or with data inappropriately aggregated to the national, rather than the district, level. Based on results from 2007 districts in 183 lower chamber elections across 21 countries, we find evidence that new electoral rules, the entry of new parties, past electoral volatility, and high district magnitudes are all likely to make coordination a challenge, with entry by new parties having the largest, most consistent effect.     

Determinants of disproportionality and wasted votes

The aim of this article is to explain differences in disproportionality. The dependent variable has two components. One is the index of disproportionality created by Michael Gallagher (1991). The other component consists of the amount of wasted votes, i.e. votes that are given to representatives of parties which fail to gain representation in parliament. Three independent variables are used: district magnitude, electoral thresholds, and the combined measurement of these variables, namely the effective threshold. The test reveals that while Gallagher's index of disproportionality is affected by district magnitude and the effective threshold, the amount of wasted votes remains, with the possible exception of a weak link to electoral thresholds, unaffected by changes in the independent variables. Explanations for the findings are introduced and discussed.     

Electoral bias at the 2015 general election: reducing Labour’s electoral advantage

Electoral bias results in an asymmetrical seat distribution between parties with similar vote shares. Over recent British general elections Labour held an advantage because it efficiently converted votes into seats. Following the 2015 election result this advantage has reduced considerably, principally because Labour’s vote distribution saw it accumulate more ineffective votes, particularly where electoral support was not converted into seats. By contrast, the vote distribution of the Conservative party is now superior to that of Labour because it acquired fewer wasted votes although Labour retains a modest advantage overall because it benefits from inequalities in electorate size and differences in voter turnout. Features of the 2015 election, however, raise general methodological challenges for decomposing electoral bias. The analysis, therefore, considers the effect of substituting the Liberal Democrats as the third party with the United Kingdom Independence Party. It also examines the outcome in Scotland separately from that in England and Wales. Following this analysis it becomes clear that the method for decomposing electoral bias requires clearer guidelines for its application in specific settings.     

Incentives to cultivate a personal vote: A rank ordering of electoral formulas

Seat allocation formulas affect candidates' incentives to campaign on a personal rather than party reputation. Variables that enhance personal vote-seeking include: (1) lack of party leadership control over access to and rank on ballots, (2) degree to which candidates are elected on individual votes independent of co-partisans, and (3) whether voters cast a single intra-party vote instead of multiple votes or a party-level vote. District magnitude has the unusual feature that, as it increases, the value of a personal reputation rises if the electoral formula itself fosters personal vote-seeking, but falls if the electoral formula fosters party reputation-seeking.     

The unfortunate natural experiment in ballot design: The Scottish Parliamentary elections of 2007

The 2007 Scottish Parliamentary elections were notable for the extensive variation across constituencies in rejected ballots (ranging from 1.90% to 12.09%). This paper uses an unfortunate natural experiment to identify the influence of ballot design on the occurrence of rejected ballots, or ‘residual votes’. In two electoral regions, visual prompts were removed and instructions were abbreviated on the (already poorly designed) ballot papers. Using zero-truncated negative binomial regression to model total residual votes as well as constituency and regional undervotes and overvotes, we find clear evidence that these changes made a major contribution to the extent of residual votes in constituencies within those regions. The findings emphasise that ballot design is not a trivial subject that can be neglected by electoral administrators.     

Which Electoral Formula Is the Most Proportional? A New Look with New Evidence

A ranking exists in electoral systems research of differentelectoral formulas—the mathematical functions governingthe conversion of votes into legislative seats—in termsof both proportionality of seats and votes and favorabilityto the largest party. I reexamine this issue with new methodsand new evidence, attempting to cross-validate previous rankingsusing a larger and more controlled data set and more preciseparametric methods than have been applied previously. The resultsby and large confirm previous knowledge but also illuminateseveral important new facets obscured in previous investigations.For example, at common ranges of district magnitude (from 5to 15 seats), it is shown that electoral formula may matterat least as much as district magnitude in shaping proportionality.     

Anti-immigrant parties in Europe: Ideological or protest vote?

Abstract. In this article we address the question whether or not the votes for anti–immigrant parties can be considered as protest votes. We define protest votes by the motives underlying electoral choices, building on earlier research done by Tillie (1995) and Van der Eijk & Franklin (1996). That research showed that ideological proximity and party size are the best predictors of party preference. On this basis we designed a typology of motives for party choice and how these motives would manifest themselves empirically. Analyzing the 1994 elections for the European Parliament for seven political systems we show that anti–immigrant parties attract no more protest votes than other parties do, with only one exception: the Dutch Centrumdemocraten. Voting for anti–immigrant parties is largely motivated by ideological and pragmatic considerations, just like voting for other parties. In addition, (negative) attitudes towards immigrants have a stronger effect on preferences for anti–immigrant parties than on preference for other parties. Social cleavages and attitudes towards European unification are of minor importance as determinants of preferences for anti–immigrant parties. The overall conclusion is that a rational choice model of electoral behavior has strong explanatory power for party preferences in general, but also for the support for anti–immigrant parties in particular.     

Distinguishing between the effects of swing ratio and bias on outcomes in the US Electoral College, 1900–1992

We review a number of different statistical techniques for creating seats-votes curves and apply the most reliable of these to estimate seats-votes relationships in the US electoral college 1900–1992. We consider the now rejected claim, once firmly established as part of the common journalistic and even academic wisdom, that the US Electoral College has recently been strongly biased in favor of Republicans, and show that this claim was based largely on a confusion between bias (asymmetry in the electoral college gains earned by the votes received by different parties or candidates) and swing ratio (responsiveness of change in electoral college seat share to change in popular vote). Although there has been substantial bias during this century in the way the electoral college translates Democratic and Republican votes into electoral college seats, and for the earlier party of this century (from 1900 to 1940) that bias has been in favor of Republicans, to explain why many recent electoral college majorities have been so lopsided we must look not at bias but at swing ratio.We show that the swing ratio in the electoral college has generally been increasing since 1900, rising from an average value (1900–1924) around three to an average value (1976–1992) ranging from about five to about eight, depending upon which of the various statistical estimation techniques we use. Thus, for every one point vote share gain above 50 per cent, a winning presidential candidate in a two-candidate competition can now expect to pick up somewhere between a 5 percentage point and an 8 percentage point increase in electoral college seats—giving the illusion of mandate even for relatively close contests and frequently creating apparent landslides. We show that this historical rise in swing ratio in presidential elections is due almost entirely to changes in the responsiveness of outcomes in the US South as the influence of the Civil War slowly (very slowly) erodes. Drawing on the analysis of the determinants of bias and of swing ratio in the House of Representatives in Brady and Grofman (1991b), we show that the increases in electoral college swing can be accounted for by the nationalization of presidential competition as signaled by the decrease over time in the standard deviation of Democratic share of the two-party vote across states, and that changes in bias can be linked to changes in the magnitude of differences between the mean and the median of that distribution.
