Incumbency advantage in multi-member districts: Evidence from congressional elections in Chile

Do parties enjoy an advantage to incumbency in multi-member districts? In this paper we answer this question by adapting a regression-discontinuity design to multi-member districts in congressional elections in Chile. The electoral system in place generates discontinuities in the number of elected representatives from each coalition at the 1/3 and 2/3 thresholds of the two-party vote share. Regression-discontinuity estimates indicate that, by holding two seats as opposed to holding only one, the left-leaning coalition obtains an extra 4.5% vote share in the next election and increases by 28 percentage points the probability of electing two candidates again. These results are in line with those obtained in previous studies in the U.S. but contrast with results obtained in developing countries which find a negative advantage to incumbency.     

The disadvantaged incumbents: estimating incumbency effects in Indian state legislatures

This paper estimates the incumbency effects using a large dataset on state legislative elections in India during 1975–2003. I use a Regression Discontinuity Design (RDD) that estimates the causal effect of incumbency by comparing candidates in closely fought elections. I find that there is a significant disadvantage to incumbency in Indian State legislative elections, and the adverse effect of incumbency has increased after 1991. Also, the incumbency disadvantage is higher in states that have lower availability of public goods such as health centers, and lower employment, poverty and per capita income.     

Incumbency advantage and candidate characteristics in open-list proportional representation systems: Evidence from Indonesia

We use evidence from Indonesia's April 2014 legislative elections to study the relationship between incumbency, list position, candidate characteristics, and electoral success in open-list PR systems. Contrary to a recent literature identifying an incumbency disadvantage in other large developing democracies, we identify a consistent personal incumbency advantage in Indonesia. However, we argue that this advantage is mediated by party choices over how incumbents and newcomers are ranked on party lists, a key heuristic for voters in low-information electoral environments such as Indonesia.     

The incumbency advantage in second-order PR elections: Evidence from the Irish context, 1942–2019

Do candidates in local elections benefit from an incumbency advantage? And which factors moderate the strength of this incumbency bonus? Analyzing seven decades of Irish local elections (1942–2019) conducted under proportional representation through the single transferable vote, we reassess and extend the mixed evidence on the incumbency advantage under proportional representation and in second-order elections. By applying the Regression Discontinuity Design, we find that the incumbency advantage is at least as strong in Irish local as in general elections, which are conducted under the identical electoral system. We also show that marginally elected candidates in local elections have much higher reelection probabilities when they do not face a high-quality candidate in their local electoral area after getting elected. The findings point to the importance of name recognition as a major driver of the incumbency advantage in local elections.     

Risk Attitudes and the Incumbency Advantage

Explanations for the incumbency advantage in American elections have typically pointed to the institutional advantages that incumbents enjoy over challengers but overlook the role of individual traits that reinforce this bias. The institutional advantages enjoyed by incumbents give voters more certainty about who incumbents are and what they might do when (and if) they assume office. We argue that these institutional advantages make incumbents particularly attractive to risk-averse individuals, who shy away from uncertainty and embrace choices that provide more certainty. Using data from 2008 and 2010 Cooperative Congressional Election Study, we show that citizens who are more risk averse are more likely to support incumbent candidates, while citizens who are more risk accepting are more likely to vote for challengers. The foundations of the incumbency advantage, we find, lie not only in the institutional perks of office but also in the individual minds of voters.     

Beyond personal vote incentives: Dividing the vote in preferential electoral systems

Comparative studies of preferential electoral systems have paid much attention to the incentives for personalized instead of party-centered campaigns, but they have largely ignored how some of these systems allow “allocation errors” and so create incentives for parties to “manage” the vote and intraparty campaigns. We discuss how the single non-transferable vote (SNTV) and single transferable vote (STV) systems create these incentives, and we illustrate the degree to which they affect actual electoral results across seven preferential electoral systems. The analysis reveals statistically significant differences in the vote inequality among incumbent cohorts (members of the same party and district), indicating the strong influence of vote division incentives over candidate-centered electoral environments. The results also have important implications for comparative research on legislative turnover and the incumbency advantage.     

The impact of incumbency on turnout. Evidence from Italian municipalities

We analyse how the presence of an incumbent among candidates at an election affects electoral turnout. We use a rich data set which provides information on the results of Italian municipal elections over the period 1993–2011. We find that the impact of incumbency is heterogeneous across geographical areas: incumbency produces a positive effect on turnout in the South of Italy, whereas we find a negative and statistically significant effect in the North. We speculate that the north-south divergence is related to differences in social capital and in clientelistic relationships established by incumbent politicians. Our conjecture finds support when we look separately at municipalities in the lower and upper quartile of the social capital distribution and at municipalities with high or low densities of organised crime.     

Japan's new electoral system:: la plus ça change . . .

We examine the impact on parties and candidates of Japan's new electoral rules, first used in the 1996 House of Representatives election. We argue that the Japanese rules, which not only permit dual candidacy but also allow votes cast in the single member district (SMD) portion of the race to allocate proportional representation (PR) seats to dual candidates, effectively defeat the purposes of electoral reform. The new arrangement transforms PR representatives into locally-based politicians who will rely on personalistic rather than party-based or programmatic campaigning, effectively converts single-member districts back into the multi-member districts of the past, enhances incumbency advantage, and will push the ratio of candidates to seats down as low or even lower than before.     

Incumbency effects in political campaigns

In this paper we examine two effects of incumbency. First, an incumbent may have an advantage in creating a favorable image in the eyes of the voters. Second, the incumbent may have to chose a position before the challenger; this second aspect of incumbency is modelled as Stackelberg leadership. In the model two candidates run for election by choosing a position in an ideological spectrum. Voters care about candidates' chosen positions as well as non-policy attributes of candidates, which we call charisma. Charismata are not known when candidates choose policy positions; they are only revealed on election day so that winning is not usually a certain prospect. Candidates care about the probability of winning but they also dislike compromising their own ideals.We find that the incumbent's equilibrium position is closer to his/her own ideal point than the equilibrium position of the game when moves are simultaneous. Also, for sufficiently large charismatic differences a natural leadership regime prevails: the candidate with the large charismatic advantage prefers being a leader to being a follower and the opponent prefers being a follower. If the difference in charismata is small both players prefer to be followers     

You just made it: Individual incumbency advantage under Proportional Representation

Using close election outcomes, we identify a personal effect of incumbency on the probability of seeking election, and seeking and winning office in subsequent elections for elected officials in an Open List Proportional System. In many cases Danish local elections creates an as-if random distribution of candidates that are elected or not, which is an ideal setting for a Regression Discontinuity design. The incumbency advantage has been studied to a great extent, though primarily in pluralistic electoral systems, while more recent studies have extended the scope to Proportional Representation systems. This study adds to this budding literature by showing an advantage in a new context and focusing on candidate level electoral returns under conditions where candidates are arguably least likely to benefit from incumbency.     

Campaign resources and electoral success: Evidence from the 2002 French parliamentary elections

We examine the factors that improve the candidates’ likelihood of winning an election by drawing on information from campaign resources used by candidates running in the 2002 French parliamentary election. The main effects that we wish to analyze are the candidates’ gender, political affiliation and possible incumbency. We find that the contributions the candidates received and their political affiliations determine their acceding to the second round of the elections. But surprisingly once they make it to the second round, the contributions cease to be relevant; only the candidates’ gender, incumbency and the actual spending rather than the contribution levels matter.     

The June 1999 European Parliament elections

In countries with a majoritarian electoral system, the expenses of challengers are generally found to have a stronger effect on the electoral outcome than the expenses of incumbents. Research on campaign expenditure effects in Brazil suggests that this is not the case in countries with an open list PR system and large districts. This hypothesis is confirmed by an analysis of the effect of individual campaign expenses on the number of preferential votes in the 2003 legislative elections in Flanders/Belgium. An analysis of high quality candidates shows that the expenses have a substantial effect on the vote which does not vary according to incumbency status. However, the effect of media exposure on the vote is stronger than and largely independent of the effect of campaign expenses.     

Multi-level muddling: Candidate strategies to “nationalize” local elections

Comparative literature has identified how political parties at subnational levels strategically refer to the performance of parties or policy issues at national level to varying degrees. Building upon these studies on multi-level electoral dynamics, the article demonstrates how individual legislative candidates, and not just parties, selectively adopt what we call “cross-level electoral appeals”(CLEAs): campaign messages which emphasize issues, performances, and actors in levels of government other than that which the candidate or party is seeking office. Advancing existing conceptualizations of nationalization, we posit that there are mainly three types of such CLEAs, those in which local candidates: 1) praise or criticize a specific national policy or 2) performance of the national government; or 3) emphasize personal linkages to national-level parties or politicians. The article investigates the potential factors which lead to more frequent CLEAs by observing candidate manifestos for local legislative elections in Japan. We use an original dataset from a sample of prefectures differently affected by specific national policies, candidates affiliated to parties differing in organizational centralization and from districts varying in seat magnitude as well as incumbent party popularity. To test hypotheses about national and local level party popularity as well as district-level variables on the frequency of such appeals, the article analyzed the data set using the novel methodology of not just counting, but also measuring the surface area of specific appeals in candidate manifestos. Through regression analysis, we find evidence of national government party popularity leading to more frequency of local candidate CLEAs. We also find that local candidates who are more dependent on the party vote (i.e. those in smaller district magnitudes and in centralized party organizations) are more prone to certain types of CLEAs.     

Informative and persuasive campaigning

In this paper we use a simple Downsian spatial model to analyze the properties of campaign contributions. We first consider campaign contributions that are intended to inform voters of candidate positions. We show that it is difficult to construct arguments in a Downsian spatial model for why some voters would choose to contribute to a candidateand the candidate would want to spend the money contributed to inform voters of his position. We then define persuasive campaign expenditures as those that are intended to convince an individual to vote for a candidate regardless of the candidate's position on issues. In the presence of persuasive campaign expenditures some voters have an incentive to contribute to one or both candidates, and the candidates have an incentive to spend the money. We show why the nature of persuasive campaign expenditures may explain both their growth in recent years and the increasing advantage of incumbency.     

The rise of negative partisanship and the nationalization of U.S. elections in the 21st century

One of the most important developments affecting electoral competition in the United States has been the increasingly partisan behavior of the American electorate. Yet more voters than ever claim to be independents. We argue that the explanation for these seemingly contradictory trends is the rise of negative partisanship. Using data from the American National Election Studies, we show that as partisan identities have become more closely aligned with social, cultural and ideological divisions in American society, party supporters including leaning independents have developed increasingly negative feelings about the opposing party and its candidates. This has led to dramatic increases in party loyalty and straight-ticket voting, a steep decline in the advantage of incumbency and growing consistency between the results of presidential elections and the results of House, Senate and even state legislative elections. The rise of negative partisanship has had profound consequences for electoral competition, democratic representation and governance.     

The alternative incumbency effect: Electing women legislators in Indonesia

Between the 1999 and 2009 elections the proportion of national female legislators in Indonesia, the world's largest Muslim majority democracy, more than doubled. While this substantial increase may partly be explained by the recent imposition of a gender quota and placement mandate that have forced parties to increase the number of female candidates, quotas cannot fully explain the strong performance of women in the 2009 elections. First, many parties placed women higher on their lists than the laws required; second, voters appeared to over vote for women in some districts. Although incumbency's typical effect is to inhibit female electoral success by advantaging traditional (male) competitors, I argue that women benefited largely from an alternative effect: female incumbency can improve female candidate placement and electability by demonstrating female capacity and capability. Female newcomers benefited strongly from the presence of female incumbents in their own and bordering districts, thus suggesting a positive diffusion effect of female incumbency.     

The Variable Incumbency Advantage: New Voters, Redistricting, and the Personal Vote

In this article we explore the personal vote costs of redistricting. After redistricting, incumbents often face significant numbers of new voters—voters that were previously in a different incumbent's district. Existing conceptualizations of the incumbency advantage suggest that the cost to incumbents of having new voters should be relatively small and predictable. We propose a different formulation: a variable incumbency advantage. We argue that any incumbency advantage among the electorate is a function of short-term effects, partisanship, and electoral saliency. We use a massive untapped dataset of neighborhood-level electoral data to test our model and to demonstrate how the intersection of the personal vote, redistricting, and short-term environmental variables can provide a healthy margin to incumbents—or end their careers.     

Who benefits? Intergovernmental transfers,subnational politics and local spending in Ecuador

ABSTRACT

This paper looks at the intervening role that local political elites play to translate government transfers into effective public spending. We want to know whether mayors spend IGTs to provide basic public services or infrastructure works, and whether such investments are instrumental to secure their advantage as incumbents. To test these arguments, we use a combined dataset of local public finances between 2001 and 2015 and electoral results for the 2009 and 2014 municipal elections in Ecuador. We find that mayors do respond to political incentives and make strategic spending decisions to invest on public services and visible infrastructure projects. However, we find selective spending was insufficient to secure incumbency advantage in the 2014 election. We argue that the executive intervened to block or limit the impact of spending decisions at the local level, thus creating an incumbency disadvantage for mayors. Further research is needed to explain this.     

Bringing home the votes: Electoral outcomes in state legislative races

This analysis assesses the effects of campaign activity, measured in terms of the campaign expenditures of candidates, on the outcomes of state legislative elections. The research utilizes election results from the 1978 elections for the state houses in California and Iowa. In addition, the investigation specifies the influence of partisan strength and incumbency on election outcomes. Two multiple regression models are estimated, one in which the partisan vote outcome is the dependent variable and one in which the vote of challengers is the dependent variable. Although the results of the inquiry underscore the partisan character of state legislative races, they also show that, akin to congressional contests, a challenger's campaign spending can sometimes have a greater effect on the voting outcome than the incumbent's spending. But these state legislative elections are largely partisan affairs in which bringing home the votes mainly involves support for political parties in the legislative districts and the intensity of campaign efforts represented by campaign expenditures.     

Does Quality Matter? Challengers in State Supreme Court Elections

We assess whether quality challengers in state supreme court elections have a significant impact on the electoral successes of incumbents and whether the electorate seemingly makes candidate-based evaluations in these races. To address these questions, we examine 208 elections to the states' highest courts from 1990 through 2000 in the 21 states using partisan or nonpartisan elections to staff their benches. From a Heckman two-stage estimation procedure that takes into account factors influencing challengers' decisions to run as well as factors affecting the electorate's choices among candidates, we find that quality does matter. Experienced challengers significantly lessen the electoral security of incumbents, and the electorate appears to evaluate challengers' qualifications. These findings stand in stark relief to traditional notions that the electorate is incapable of responding to candidate stimuli beyond incumbency and that judicial elections inherently are an ineffective means for securing popular control over the bench.
