How representative is a self-selected web-panel? The effect on representativeness of different sampling procedures and survey modes
- 2012

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper makes a systematic comparison between different sampling procedures and survey modes by making use of three different types of surveys. In all three surveys, identical questions and wordings are used. However, they are all three separate studies whereas the first study is based on a representative sample of approximately 3 000 Swedish citizens (based on the national census register). This study is carried out as a traditional postal survey by the Swedish SOM-institute. The second study is also based on a representative sample of approximately 3 000 Swedish citizens (recruited by telephone from the national census register), but in this case the survey is entirely carried out as a web-survey, distributed by e-mail. The third and final study is carried out as a web-survey as well but is instead based on a selfrecruited citizen panel of 10 000 Swedish citizens. All three surveys were carried out during October to December, 2011. In order to evaluate potential differences between varying sampling procedures and survey modes, we will a) compare the composition of respondents in terms of general SES-related background characteristics between the three surveys, both in terms of potential differences in levels and correlations, and b) analyze the differences in three sets of questions tapping, values, attitudes and behavior. By doing this we will be able to uncover how representative a large-sample self-recruited panel actually can become as well as what the usage of new technological media in surveys does to an initially representative sample in a technologically advanced country. Important questions that we will be able to answer concerns to what extent different sampling procedures and survey modes affect the representativeness of a sample? If potential differences varies between different types of survey questions, i.e. questions relating to values, attitudes and behavior etc.

Issue ownership - How can it be stolen?
- 2011

Ingår i: MPSA.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Issue ownership (IO) has been an important concept in the analysis of party behaviour, party strategy and party competition for several decades. More recently, it has also been of growing interest to research on voting behaviour. Traditionally, IO has been regarded as a stable phenomenon where parties have different profiles and are advantaged by different political issues or issue areas. However, recently many studies have reported change and fluctuations concerning IO. In order to investigate the changeability of issue ownership and how it can be changed, we have experimentally investigated, through a web-based survey embedded experiment, the impact of three key factors: government performance, priority signalling, and issue framing. The study focuses on one specific issue, which is employment/unemployment. Unemployment is a major political issue in many established democracies and thus worthy of attention in itself. Despite generally weak indications that our experimental manipulations managed to influence issue ownership among our respondents, two findings stand out when summarizing our results: 1) Priority signaling seems more likely to influence issue ownership than government performance or issue framing. 2) People who have moderate evaluations of a party’s policy are more likely to be influenced by efforts to change issue ownership than people who are either clearly negative or clearly positive towards party’s policy.

Is Accuracy Only For Probability Samples? Comparing Probability and Non-probability Samples in a Country with Almost Full Internet Coverage
- 2013

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Commercial on-line panels based on non-probability samples have begun to be widely used not only in traditional market research but also in more academic research. But is the quality and accuracy of such data comparable to that of probability based samples? The overall aim of this study is to compare the quality of probability based and non-probability based on-line panels in Sweden, a country with almost full internet coverage. We proceed in two steps. Firstly, we compare the accuracy of three survey modes all using random samples: postal survey, telephone survey, and web survey. Secondly, we compare the accuracy of two commercial non-probability based panels with two commercial probability based panels, using the traditional mail and telephone surveys as benchmark surveys. Demographics are compared to government records, and attitudes are compared to benchmark studies of high quality and high response rate. In order to allow comparisons, seven surveys with comparable questions were run at approximately the same time. We compare the accuracy of the four commercial on-line panels both with and without weights. In contrast to previous studies, the results indicate a surprising similarity in terms of accuracy between probability panels and non-probability panels. The two non-probability based on-line panels do not seem to be less accurate than probability based on-line panels in terms of demographics, nor do their estimates of political attitudes seem to differ more from traditional methods such as a high response rate mail survey. We conclude that a larger comparison based on more demographic and attitudinal variables are needed.

Does Politicization of Corruption Affect Voter Turnout?
- 2014
-
Ingår i: Paper presented at the Annual Meeting of the American Political Science Association, Washington, DC, August 28-31 2014.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper tests to what extent voters’ perceptions of corruption in the political system affect turnout and in particular if politicization of corruption in electoral campaigns affects that relationship. In previous research, some studies find that corruption increases turnout because voters either are bought off to participate or because they are mobilized on clean government issues, but the majority, more often country comparative studies, show that corruption decreases turnout because the presence of corruption corrodes the political system which leads to general cynicism, distrust and voter apathy. In this paper, we test a previously neglected factor, namely if politicization of corruption, defined as any party campaigning on anti-corruption issues, dampens or even reverses the presumed negative effects of perceiving political corruption on turnout. We argue that it is reasonable to believe that people’s willingness to participate will increase if parties address this important issue in electoral campaigns, as it will indicate party responsiveness to voter concerns. We apply multilevel modeling combining individual-level data and country-level data from 20 countries from the second module of the Comparative Study of Electoral Systems, country-level data from the Quality of Government Data Set and a unique data set on politicization of corruption issues in the election campaign. The findings suggest that politicization of corruption in the election to some extent dampens the negative effect of corruption perceptions on turnout, as the obtained positive interaction effect indicates that the negative effect of perceiving corruption as a problem on turnout is reduced in an election context where corruption is politicized. The results thus show that if corruption is not politicized, the individual corruption perceptions exert a significant negative effect on voting.

Battle of Agendas - Issue Faming and Language Use

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Issue framing has become one of the most important means of elite influence on public opinion. In this paper, we introduce a method for investigating issue framing based on statistic analysis of large samples of language use. Our method uses a technique called Random Indexing (RI), which enables us to extract semantic and associative relations to any target concept of interest, based on co-occurrence statistics collected from large samples of relevant language use. If "X" and "Y" both occur together with "Z", our method will relate "X" and "Y"; similarly if “X” is spoken about in terms of “Z”, our method will associate “X” to “Z”. We suggest that such semantic and associative relations are indicative – if not constitutive – of framing, and that this type of quantitative analysis therefore is an attractive method for investigating issue framing. As a first test of our proposed method, we have applied RI to a large collection of Swedish blog data from the period 2008 to 2010, and extracted semantic relations to a target concept referring to the notion ‘outsiders’. In the public debate, the concept is often used in relation to labour market issues but also to socially related issues. The analysis starts with a qualitative approach where we have been tracking the language use for the concept of ‘outsiders’ among the two dominant and opposing parties in Swedish politics. The results from this part of the study are then used as a benchmark for a deepening understanding of the framing of the issue in the blogosphere.

Democracy and Bureaucracy: How their Quality Matters for Popular Satisfaction
- 2014

Tidskriftsartikel (refereegranskat)abstract
- This study focuses on how citizens’ satisfaction with democracy is affected by system factors related to the input side of the democratic system, i.e. the electoral dimension, as well as to factors related to the output side, i.e. the quality of government. The study investigates the extent to which different election system characteristics and degrees of policy representation (in terms of ideological congruence between voters and representatives) and the presence of effective, professional and impartial governmental institutions are related to citizens’ satisfaction with the way democracy works. The study uses data from CSES on individual voters and party system characteristics together with data on governmental institutions from the QoG Institute. Overall, the results indicate that factors such as government effectiveness are of greater importance for citizens’ satisfaction with the way democracy functions, compared to factors like ideological congruence on the input side. Impartial and effective bureaucracies matter more than representational devices.

Different Surveys, Different Results? A Comparison of Two Surveys on the 2009 European Parliamentary Election
- 2014

Tidskriftsartikel (refereegranskat)abstract
- The European Election Survey (EES) is carried out in all member states at the time of each European Parliament election. The mode of data collection (mainly telephone interviews) and the sampling procedure (achieving 1,000 interviews in each country) raise doubts about the data quality. Until now knowledge has been lacking about the extent to which the mode of data collection and the sampling procedure bias the results. In one European country an independently designed election survey is carried out: The Swedish National European Parliament Election Study (SNES). The survey consists of face-to-face interviews of a random net sample of 2,682 individuals (response rate 67 per cent compared to 11.2 in the Swedish EES survey). In addition, SNES includes a large number of variables from official register data (including validated voting) that facilitates analyses without any non-responses generating missing data. This quasi-experimental methodological set up is used to compare the data from the two surveys for voter turnout, left–right placement and party choice. Results show that EES overestimates turnout levels more than SNES. EES also has a large overrepresentation of highly educated respondents, and thus underestimates differences in turnout between highly and less educated citizens. As for left–right placement, respondents in EES place both themselves and the parties on more extreme positions. Regarding party choice, the main difference between the surveys is that the EES largely underestimates the share of Social Democratic voters.

Does context matter – The impact of electoral systems, political parties and individual characteristics on voters’ perceptions of party positions
- 2013
-
Ingår i: Electoral Studies. - 0261-3794. ; 32:4, s. 670-683
-
Tidskriftsartikel (refereegranskat)abstract
- This article aims to investigate under which circumstances policy representation can exist in terms of agreement in voters’ perceptions of parties’ left–right positions. The focal point in the study is on how voters’ perceptions are affected not only by individual characteristics but also by various contextual factors related to the political parties and the political systems. With data from the CSES on individual voters and various system characteristics from election surveys in 32 countries, this article shows that what in earlier findings have appeared as national context effects rather are party effects when being decomposed. System related variables have only a small impact on voters’ perceptions while the partyfollowed by the individually related variables exerted the greatest impact.
