In this paper, we research if such an effect can be found in 18 European countries and the United States in 2004 (prior to the economic crisis) and if the tenure gap in voting, which differs by housing regime, can be explained with the different selection of people into tenures in these regimes and the different length of residence of the tenures. We find that in most countries, controlled for selection, homeowners have a higher propensity to vote, and that the differential tenure gap in voting between housing regimes can partly be explained with differences in selection into homeownership and in length of residence-effects between these regimes. Interestingly, we find that the length of residence-effect has an independent effect as long as we do not control for selection into homeownership, after controlling for selection we no longer find an effect of length of residence. 2 Introduction and Theoretical Background In many countries, the promotion of homeownership has been used as a policy instrument by governments in order to achieve economic, social and political goals (Bratt, 2012b; Dietz & Haurin, 2003; McCarthy, Van Zandt, & Rohe, 2001). Homeownership has been used to stabilize and stimulate the economy, and to provide people with a private safety net through the promotion of wealth accumulation, as part of the socalled asset-based welfare strategy aimed at low-income households (Sherraden & McBride, 2010). A social goal of homeownership policy has been to rejuvenate deteriorated neighborhoods and quell social and racial tensions. Homeownership is furthermore supposed to have a positive effect on housing quality and home maintenance and on involvement in, and hence improvement of, the neighborhood. With regard to the political consequences, it has been argued that homeownership, by giving people a stake in society, promotes confidence in the government and leads to empowerment of citizens, which in turn induces participation in the political process, enhancing democratic legitimacy (Mansfield, Van Houtven, & Huber, 2001; McCabe, 2012). One way to enhance democratic legitimacy and influence social policy is through political participation. In this paper, our main interest lies with the presumed positive effect of homeownership on political participation. So far, the effect of homeownership on political participation, with a focus on voting propensity, has mainly been researched for the United States (US). Rossi and Weber (1996), like others, found a homeownership effect on local voting in the US, but did not use appropriate statistical controls. DiPasquale and Glaeser (1999) found that homeowners vote more often in local elections, and that about half of this effect was explained by length of residence. McCabe (2013) found that homeowners are more likely to vote in local and national elections, where length of residence and respondents’ considerations with regard to their financial investment in a certain locality explained a third of the relationship. On the contrary, Engelhardt, Eriksen, Gale, and Mills (2010) found no effect for low-income homeowners in the US. These later studies controlled for other important correlates of both homeownership and voting, like age, gender, marital status, income and education. Comparative research on the – presumed – political consequences of homeownership is scarce: only two studies compared the US with a European country. DiPasquale and Glaeser (1999) found that German homeowners, controlling for length of residence, also vote more often in local elections. Glaeser and Sacerdote (2000) found no effect of homeownership on local voting in Germany, but they did find a positive homeownership-effect in the US. More recently, several studies have researched the impact of homeownership, in particular the potential to accumulate private housing wealth under different housing regimes, on welfare attitudes – more specifically support for redistribution by the welfare state. André and Dewilde (forthcoming) found that homeowners are less supportive of redistribution than tenants, varying with age, income and housing regime context. They also showed that in countries in which homeownership is more financialized, support for 3 redistribution is lower and this effect was stronger for homeowners than for tenants. Ansell (2014) found that house price changes are associated with changes in social policy preferences, and that housing wealth seems to work as a self-supplied insurance against life events: owners experiencing house price appreciation become less supportive of government redistribution. He also showed that right-wing parties respond to changes in voter preferences based on house prices, by cutting down on redistributive spending during housing booms. However, the missing link in this research is electoral participation. If homeowners do not have a higher propensity to vote than tenants, or do not have a higher propensity to change their voting preferences following housing booms and busts, this will not change policy outcomes. Therefore, in this paper the main focus is on a specific element of these assumptions: the impact of homeownership on electoral participation as a particular form of political participation. Recent electoral participation research has focused on explaining differences in turnout between social groups across countries, for example the gender gap (Beauregard, 2014; Isaksson, Kotsadam, & Nerman, 2013), the class gap (Anderson & Beramendi, 2012), the educational gap (Armingeon & Schädel, 2014) and the generational gap in electoral participation (Górecki, 2013). In addition, we propose to research the difference in turnout between homeowners and tenants, i.e. the tenure gap in electoral participation. Such a political cleavage has for instance been found in California between voting homeowners and non-voting tenants, strengthening racial differences in voting (Barreto, Marks, & Woods, 2007). We improve upon earlier research in three ways. We, first of all, extend older research on electoral participation which has focused only on the US and Germany (DiPasquale & Glaeser, 1999; Rossi & Weber, 1996) by comparing the US with 18 European countries, using more recent data. This comparison is interesting, since findings of American studies have been used to justify homeownership policy in Europe, while the history of American homeownership is very different, also from an ideological perspective. For example, in the US homeownership has been used as a strategy to motivate people to migrate to the US, develop the land and create a civic community (Bratt, 2012a). Under these circumstances, we would expect a positive effect of homeownership on political participation. In Europe on the other hand, in particular in those countries in which homeownership was promoted early on, the main motivation was to quell social unrest and to prevent the spread of urban socialist ghetto’s by means of suburban homeownership for workers (e.g. Goossens, 1983). Through their mortgages, workers are tied to the economic system – they have a stake in the stability of the system and furthermore, they need their jobs to pay for the mortgage (Castells, 1977; Engels, 1887 [1975]). The effect of this dependence on the powers that be on electoral participation is, however, ambiguous: while – based on their housing interests – homeowners may have increased confidence in the government, and thus may be more inclined to participate in the political process, they are at the same time discouraged – given their interest in a stable system – from defending 4 other interests (e.g. with regard to income or working conditions) through unionization or other political activities. Extending this argument, national homeownership policies or debates on homeownership policies (e.g. regarding the ‘fairness’ of mortgage interest-deduction, or the frustration of tenants who ‘miss out’ on the gains created through house price inflation) may influence both owners’ and tenants’ voting behavior and preferences. Taken together, interests related to homeownership cannot provide an explanation for the presumed higher propensity of homeowners to vote in the first place. We will thus turn to other explanations in this paper. Second, we take account of methodological issues with regard to the selection into homeownership. Much of the older research is criticized for not controlling for important correlates of homeownership, like income or occupational class, or for only researching low-income homeowners (i.e.Engelhardt et al., 2010; Haurin, Dietz, & Weinberg, 2003), although others found effects to hold controlling for endogeneity and selection (Aaronson, 2000). We will therefore control for the most important ‘common causes’ of homeownership and electoral participation (gender, age, marital status, income, education, occupational class and urban/rural environment). These controls also take care of composition effects, which arise from the fact that the groups of homeowners and tenants may have different characteristics in different countries. Composition effects are related to the selection of people into homeownership. Housing regimes – defined as the ‘social, political and economic organization of the provision, allocation and consumption of housing’ (Kemeny, 1981, p. 13) – differ between countries. Housing regimes influence the costs and benefits of different tenures and influence which people can enter homeownership, and why they do so. We hence expect that housing regime-differences with regard to the impact of owning versus renting on political participation can be (partly) explained by the selection of different ‘types’ of people into homeownership. Third, apart from the methodological issue of selection into homeownership, housing regimes also determine one of the main substantive explanations for the positive effect of homeownership on electoral participation: length of residence. We fill this gap by formulating and testing hypotheses with regard to the impact of housing regimes on differences between groups of owners and tenants with regard to length of residence. Unfortunately, there are no comparative data sources in which information on tenure, political participation and length of residence as explanatory mechanisms are all included at the same time. To this end, we combine data from various sources to approximate this theoretical mechanism. To summarize, our main research question reads as follows: do homeowners and tenants differ in their electoral participation across different housing regimes, and to which extent can these housing regime differences be explained by a) selection into homeownership and b) differences between owners and tenants in terms of length of residence. The focus in this paper is on national electoral participation, i.e. to vote or not to vote in national elections. We use data from the second wave of the European Social Survey (Jowell & The Central Co-ordinating Team, 2005) and the 2004 General Social Survey (Davis & Smith, 2004). 5 The paper is structured as follows. In the following section, we elaborate on the literature with regard to the social mechanisms: social characteristics, political trust and length of residence, linking homeownership to political participation. Next, we formulate hypotheses with regard to housing regimedifferences in the impact of homeownership on electoral participation, and how these relate to a) selection into homeownership (including political trust) and b) length of residence-differences between owners and tenants across housing regimes. We then describe the data and methods, present the results and end with a conclusion and discussion. Homeownership and electoral participation: social mechanisms From a rational-choice or self-interest perspective we would not expect homeowners and tenants to have a different turnout. Assuming that political parties will tailor their programs to different parts of the electorate, both owners and tenants would find a party that suits their needs and interests. This is especially the case when tenants are prospective homebuyers and owners are prospective tenants. We thus need to explore other social mechanisms that foster electoral participation of homeowners more than tenants. In the literature, three linking mechanisms are discussed: social status, political trust and length of residence. In most countries in our study homeownership is something to aspire, e.g. the American dream of housing, which is stimulated by the government (Ronald, 2008). Owned homes are furthermore often larger, of better quality and situated in better neighborhoods. People can hence derive social status from this tenure. When homeownership communicates social status and when homeowners are supposed to be ‘good’ or ‘better’ citizens, this may induce electoral participation through social pressure and social control (Rohe & Stegman, 1994). This is in line with group-based models of voting: people vote because they are mobilized by leaders to serve the groups’ interests or because they believe that they are morally obliged to vote (Feddersen, 2004). The second explanation is political trust. As already mentioned in the introduction, homeownership has been associated with economic and social benefits at the societal, neighborhood and individual level. For instance, homeownership is believed to increase neighborhood quality and social trust, and at the country level it has been used and communicated as a tool to stabilize the economy (Green & White, 1997). These benefits, achieved through homeownership could lead to more satisfaction with the government and political trust which would enhance electoral participation. However, it is also possible that political trust is a driver of both homeownership and electoral participation. People buy homes and vote more often when they have more confidence in the political and economic system. The third explanation is length of residence. Homeowners are on average more residentially stable than tenants and this has beneficial side-effects. Residential stability gives the opportunity to build social contacts in the neighborhood and it increases civic engagement, while moving, according to Putnam’s 6 (1995) re-potting hypothesis, would decrease civic engagement. Residentially stable citizens can also enjoy neighborhood and housing improvements more because of their longer length of residence (Engelhardt et al., 2010). Especially in the case of the US, the rooting of households within communities through homeownership can help individuals overcome institutional barriers and develop social networks that foster participation in the formal political process (McCabe, 2013). This is also the case in Europe where voters do not need to register, but where one has to get informed on the party programs of between five and more than a dozen parties for each election. Social contacts and social organizations can help in this process. However, it might also be the case that homeownership does not induce socially desirable behavior. If homeownership leads to a ‘sociological mosaic’ in which people flee the cities into suburbia, living their lives segregated by education, income, class and race (Putnam, 2001) this might not enhance social or democratic behavior. From the above literature review, it appears that social status, political trust and length of residence would reinforce democratic citizenship which boosts political behavior – such as voting – at the local level. We argue that it may also influence political behavior at the national level for three reasons. First, housing policy, which influences the costs and benefits of the different tenures, is made at the national level. For example, regulations on rent benefits, mortgage interest deduction and property taxation are national regulation. Secondly, voting is a habitual act. From research we know that once people have voted three times in a row they are likely to continue to vote for the rest of their lives (Plutzer, 2002). This may lead to a spill-over effect: when people vote in local elections they learn the skills to vote in national elections. Thirdly, politicians taking part in national elections are often chosen by a local electorate. This effect is considerable in countries which have many geographical electoral units. France, for instance, has 577 electoral districts, all with their own member of parliament (Gallagher, Laver, & Mair, 2006). Finally, national turnout is, on average, higher than local turnout, giving strength to the idea to research the possibility of a national electoral tenure gap. In the introduction, we already pointed out that research into the political effects of homeownership has been plagued by a lack of appropriate statistical control for variables which may lead to both a higher probability of being a homeowner, and higher levels of political participation. Therefore, we expect part of the homeownership effect to be explained through selection. Although we do not have a good measure for (increased) social status of homeowners in our data, we also include political trust and length of residence in our models, which both are assumed to increase turnout of homeowners compared to tenants. This leads us to our first general hypotheses at the micro-level: Hypothesis 1: homeowners have a higher propensity to vote in national elections than tenants 7 Hypothesis 1a: the higher propensity of homeowners to vote in national elections compared with tenants is partly caused by general differences in social characteristics, i.e. age, education and income Hypothesis 1b: the higher propensity of homeowners to vote in national elections compared with tenants is partly mediated by or caused by higher levels of political trust of homeowners Hypothesis 1c: the higher propensity of homeowners to vote in national elections compared with tenants is partly mediated by the generally longer length of residence of homeowners across countries How housing regimes influence selection into homeownership, length of residence and voting Housing regimes – defined as systems of housing provision, allocation and consumption (Kemeny, 1981) – differ across countries and have changed much in recent decades. Housing finance has been liberalized and part of the social housing stock in several countries has been sold to (sitting) tenants, as part of a neoliberal policy orientation in, for example, the United Kingdom (UK) and as part of the privatization and restitution policy following the transformation from a planned to a market economy in post-socialist countries, such as Slovenia. Housing regimes have at least two effects: selection of citizens into tenures and the residential stability of owners versus tenants, both of which differ between housing regimes. The first impact of housing regimes refers to selection. Housing regimes influence the costs and benefits of different tenures, making homeownership and the (social) rental sector more or less attractive for certain groups of citizens. Governments can, for example, broaden or narrow the conditions of entrance in the social rental sector. Most often, governments promote one tenure at the expense of others (Kemeny, 1981; Ronald, 2008). For example, mortgage interest deduction (MID) makes homeownership a much more attractive tenure compared to the (private) rental market. A second impact of housing regimes arises from differences in the residential stability of owners versus renters. It has been found consistently that homeowners are more residentially stable than tenants (i.e. McCabe, 2013). Reasons mentioned are: financial investment in the house and neighborhood, connection to the local job market and the economic system and higher costs of moving for homeowners. However, tenants might be more inclined to stay put when there is more security of tenure, e.g. public housing can be entered on a low-income, but people do not move out when they have a higher income because of security of tenure and/or lacking attractive options (OECD, 2011). This means that security of tenure in combination with high-quality, but relatively cheap (social) housing makes tenants also invested in their house and neighborhood, which in turn increases their moving costs. Housing regimes thus result in different lengths of residence for owners (higher) compared with tenants (lower), through regime differences in i.e. transaction costs and tenure (in)security. This gap in length of residence between homeowners and tenants, which systematically differs between countries, can mediate the impact of housing regimes on voting. In other words, the different tenure gap in electoral participation between 8 housing regimes can be (partly) explained with length of residence-differences between owners and tenants across countries. In the next section, we further elaborate on four distinguished housing regimes, and on their impact on the tenure gap in voting though selection and length of residence-effects. Four housing regimes and two hypotheses While homeownership has become the majority tenure in most European countries, it developed in different times and for different reasons. We distinguish between four housing regimes: market-based homeownership, family-based homeownership, post-socialist homeownership and the ‘rent & ownregime’. For each regime we will lay out our expectations with regard to the tenure gap in voting and argue how this gap has (or has not) come about through selection and length of residence-effects which vary systematically between housing regimes. The market-based homeownership regime The market-based housing regime consists of France, Ireland, Iceland, Norway, the UK and the US. These countries have an active homeownership policy, reflecting an ideological preference for the provision of state-supported mortgaged-based homeownership (Ronald, 2008). Policy measures to promote homeownership were: mortgage interest deduction, right-to-buy of council housing, capital gains tax exemptions and increased loan-to-value ratios (LTV). The government is mostly focused on homeownership as the dominant tenure, creating a marginalized social housing sector combined with a lessregulated private rental sector (a so-called ‘dual rental market’). The young and households with limited income are more often found in the rental sector. However, (social) renting is marginalized, leaving poorer tenants with the worst-quality houses in the least popular neighbourhoods. The groups that are selected into homeownership are also the groups that are expected to vote more often in elections (higher incomes, higher education, older age groups).We thus expect the effect of selection to be large. Renting is a transitional state for the young and for those who fall out of homeownership. Renting is a permanent tenure for the poorest households, who however have to deal with higher levels of tenure insecurity than in other regimes. Overall, we expect people to stay longer in homeownership and shorter in the rental sector, resulting in a larger difference in length of residence between owners and tenants in the market-based regime. However, market-based homeownership countries often have dynamic housing markets (van der Heijden, Dol, & Oxley, 2011), which means that people move often in their housing career (moving up and down the housing ladder), resulting in a shorter length of residence for homeowners compared to homeowners in more static housing markets. Combining effects of selection into homeownership and length of residence-differences between owners and tenants, we, however, expect the tenure gap to be largest in this regime. 9 The family-based homeownership regime The family-based homeownership regime contains Greece, Italy, Portugal, and Spain. Homeownership in these countries is outright and mainly provided by the family through self-provision, pooling intergenerational family resources to bridge the gap between needs and welfare state provision (Allen et al., 2004). Although the mortgage market is developing in these countries, the LTV is in general moderate, creating the need for families to provide financial help to bridge the mortgage gap. Although the government hardly intervenes in the homeownership market, the housing trajectory is strongly focused on homeownership. The social rental sector is very small, and most people on a lower income live in a family-owned house (Allen et al., 2004). The private rental sector, which is about 20% of the tenure stock, consists, on average, of lower-quality housing. People in the rental sector are young households that did not make the transition into homeownership yet. Compared to the market-based regime, we expect that tenants consist to a larger extent out of young people (who are more politically active than the poor) and to a smaller extent out of poor people (who are less politically active). The impact of the housing regime on the tenure gap in voting is thus less strongly related to selection. Since the rental sector is mostly a transitional sector for the young we expect the average length of residence to be short. Furthermore, the family-based regime has a static housing system; people are unlikely to move but rather modify their existing home (van der Heijden et al., 2011). This means that the length of residence-effect in this regime is expected to be larger than in the market-based regime, suggesting a stronger impact of the housing regime on the tenure gap. The rent & own-regime Our third regime is the ‘rent & own-regime’, which is characterized by unitary rental markets and consists of: Austria, the Czech Republic, Germany, the Netherlands, Sweden and Switzerland. A unitary rental market consists of, alongside a strongly regulated private rental market, a historically large social rental sector which was accessible for most inhabitants, which means there are no of few income requirements. In the rent & own-regime this came alongside with varying degrees of mortgage-interest deduction supporting homeowners. The lower income groups have access to better quality rental houses and the middle income groups can choose between homeownership and public or private renting. There are government benefits for both tenures in the rent & own-regime. In general, the higher income groups are in homeownership and the lower income groups are predominantly in the rental sector, while the middle class is divided amongst these two tenures. We therefore expect the selection-effect to be small. 10 Because the social rental sector is not marginalized, offers high-quality housing and tenure security, people stay longer in the rental sector than in other regimes. In a unitary rental market, people move in and out of the different tenures based on their life course stage. Very broadly, when in college people rent, they enter home-ownership before family formation and rent again in old age. This goes alongside corresponding urban-rural movements. Furthermore, these are, in general, dynamic housing markets with high turnover rates. We would therefore expect shorter lengths of residence of owners compared to the family-based regime. Combined, the presence of a unitary rental market and high turnover rates should have as a consequence that length of residence of owners and tenants is more similar in these countries. Compared to the market-based regime, we hence expect the tenure gap in voting to be smaller. The Czech Republic can be classified as a unitary rental market because of its large social rental sector, and the country also has a different homeownership policy than the other Eastern- European countries in our sample (see next section). For example, the Czech Republic has the same Bausparen system as Germany which is also classified as ‘rent & own’ (Donner, 2006; Lux, 2001). The post-socialist homeownership regime The post-socialist homeownership regime encompasses Poland, Slovenia and Slovakia. In the post-socialist regime, homeownership rates are extremely high and mostly non-mortgaged, like in the family-based regime. This is the outcome of privatization, the sale of public rented property to tenants below market prices and the restitution of property to pre-communist owners. Although homeownership rates are high, houses were often unfit and in a bad condition (Lux, Sunega, & Katrňák, 2013; Mandic & Clapham, 1996). This means that there is hardly any difference in the quality or benefits normally associated with homeownership compared to renting. We therefore expect the tenure gap in voting arising from the selection into homeownership to be small or non-existent in this regime. Furthermore, we expect length of residence to be quite equal, because there is nearly now possibility to change housing within or between the rental sector and owner-occupation in 2004, so people are forced to stay put. In Table 1, we present the four regimes, their countries and the housing market characteristics of these countries. Hypothesis 2: the tenure gap in electoral participation is largest in the market-based regime, followed by the family regime, while a smaller gap is expected in the rent & own-regime and no effect is expected in the post-socialist regime Hypothesis 3: the tenure gap differences in electoral participation between housing regimes can be (partly) explained by the systematic differences in length of residence between homeowners and tenants, and by the different selection into homeownership 11 [Table 1 about here] Data and methods To analyze our research question we use data for 18 European countries1 from the 2004 European Social Survey (Jowell & The Central Co-ordinating Team, 2005) and the 2004 General Social Survey for the US. We use post-stratification weights to correct for sampling, non-response and design. Variables The question on voting posed in ESS was: “Some people don’t vote nowadays for one reason or another, did you vote in the last [country] national election in [month/year]?” For the US the question was: “In 2000, you remember that Gore ran for President on the Democratic ticket against Bush for the Republicans. Do you remember for sure whether or not you voted in that election?” We recoded the variable as yes (1) and no (0) and excluded those not eligible to vote. We coded if any member of the household owned the dwelling (yes/no). Unfortunately we do not know if people are in the public or private rental sector or live rent free if the home is not owner-occupied. This limits our understanding of renting citizens or of owners when they are not living in the owned house, but rent somewhere else as their main residence. Age is calculated from the year of birth and centered on the grand mean. Gender is recoded into female. Education is measured as: (1) less than lower-secondary/less than high school, (2) lower-secondary complete, (3) post-secondary/tertiary, bachelor, master and (4) education missing. Each respondent was asked to indicate in which income class their household income falls. Income is then measured as the relative household income percentile that a respondent belongs to in his/her country based on the class means of the income variable. Marital status is measured with four dummies; ‘married or living together’; ‘single’; ‘divorced’ and ‘widowed’. Urban/rural living is also measured with four dummies: ‘big city’, ‘suburbs’, ‘small city’ and ‘rural area’. Occupational status was measured as ISEI and transformed from ISCO88. ISEI gives an indication of the cultural and economic resources that are typical for a certain occupation, and it incorporates how education translates into earnings (Ganzeboom & Treiman, 2014). For those who did not have a valid ISCO-score, because they were housewives, long-time unemployed, students or because they did not answer the question, the mean-ISCO score was imputed and a dummy variable created. This dummy controls for the imputation of occupational status. Political trust is operationalized as the mean score on the partisan trust items in the survey (ESS: politicians, parties and parliament, GSS: congress and executive branch of the federal government) (Rothstein & Stolle, 2008), because only trust in partisan institutions would enhance turnout. Length of residence was not available in the 2004 waves of ESS and GSS. Therefore we used other data sources and merged the outcome with our original dataset. Length of residence was when possible 12 calculated from EU-SILC 2005, although we used other years for Norway (2006) and Switzerland (2011). We first made the samples comparable to the ESS and GSS by only including people 18 years and over. Then we randomly selected one person per household for our calculations. We measure the length of residence based on the date of purchase of the house or the date of installment of the contract. We calculate the average length of residence of groups of citizens based on four age groups (18-35, 36-50, 51-65, 65+), gender, married or not, education (low, middle, high) and tenure (homeowner, tenant). We imputed the length of residence based on these groupings for each respondent in our dataset. We used the same procedure for the US with the 2002 General Social Survey and the 2006 wave of the Dutch LISS panel. The descriptives of the variables used can be found in Table 2. [Table 2 about here] Method Mood (2010) showed that logits or odds ratios cannot be used as effect measures because they also reflect the unobserved heterogeneity in the model. Because the unobserved heterogeneity can differ between models or groups, these effects cannot be compared across models based on identical samples. To test mediation and interaction models it is thus better to use a different approach. In this case we use linear probability models (LPM), which yield unbiased and consistent estimates of a variable’s average effect on the chance that the event occurs. The b-coefficients in LPM can be read as average marginal effects on the likelihood of voting (Matter & Stutzer, 2014). We use a multilevel linear probability model to account for the clustering of individuals in countries and to include the possibility of a random slope of homeownership, since we expect the effect of homeownership to vary across countries (Snijders & Bosker, 1999). We also performed the same analysis with country fixed-effects and conclude that our results are robust 2. Results Our most general micro-level hypothesis predicted a positive effect of homeownership. Homeowners are expected to have a higher propensity to vote in national elections compared to tenants because they have a higher social status, have more political trust and are more residentially stable. We do not have a measure for social status; however, we will test for length of residence and political trust in the multi-level models. Table 3 shows the turnout of homeowners and tenants in all countries separately, the tenure gap in electoral participation as well as the bivariate and controlled effect of homeownership on voting. We control for age, gender, marital status, education, income, urban/rural status, occupational status and political trust. In the market-based regime we find a significant effect in France, Ireland, Norway, the UK and the US, which was expected based upon their homeownership policy. For example, in the UK the probability 13 of a homeowner to vote in national elections increases with 0.10 or is 10 percentage points higher than for tenants. We, however, do not find a significant effect in Iceland. In the family-based regime, there are two countries with a significant effect (Greece and Spain), while the other countries show no effect after we control for selection and political trust. A possible explanation for this difference is that house prices (and mortgage debt) increased much more in Spain and Greece between 2001 and 2004 than in Italy and Portugal (EMF, 2009), making homeownership a possible driver of electoral participation through capital gains. The difference between the controlled and uncontrolled effects in Greece and Spain are very small, indicating that it is not selection that drives the tenure gap. In the ‘rent & own’ regime, we find significant and consistent effects, which are on average half of the effect in the market regime. The effect is largest in Switzerland (0.08) and is not significant in the Netherlands. The post-socialist regime shows no effect of homeownership on voting, which is also in line with our expectations. Since we find a significant effect in most countries, after controlling for selection, we can confirm hypothesis 1 on the homeownership effect on turnout. There exists a tenure gap in electoral participation. We can also conclude that about half of the tenure gap arises from selection, although such a process is more prominent in the market regime and rent & own-regime than in the family-based regime. [Tables 3 and 4 about here] Table 4 tests the other three micro-level homeownership hypotheses: can the tenure gap in voting be explained by selection, length of residence, political trust or a combination of these? We show the multilevel linear probability models in Table 4. Hypothesis 1a predicted that the tenure gap could be partly explained through general differences in social characteristics. We can confirm this hypothesis, because the homeownership effect reduces from 0.13 in model 1 (M1) to 0.08 in model 2a (M2a) and this reduction is significant (χ²=19.01, p=0.000). Hypothesis 1b predicted the tenure gap to be partially mediated or caused by higher levels of political trust of homeowners; we test this hypothesis in model 2b (M2b). Although the effect of political trust is significant, the homeownership-effect does not change. We thus have to reject hypotheses 1b, political trust does not explain the tenure gap. Hypothesis 1c stated that the tenure gap could be explained with the generally longer mean group length of residence of homeowners across countries. When including length of residence in our models, the tenure gap decreases from 0.13 (model 1) to 0.10 (model 2c), and this reduction is significant (χ²=4.76, p=0.029). However, when we control for selection in model 4, the effect of length of residence on voting becomes non-significant and the reduction of the tenure gap is absorbed by the selection effect. This indicates that, although homeowners do tend to be more residentially stable, the presumed beneficial effects of a longer length of residence may really be due to other social 14 characteristics of homeowners, which lead to higher political participation compared to tenants. This is a novel finding, and calls into question the presumed higher sociability and participation in civil society attributed to homeownership. We thus have to reject hypothesis 1c: although the tenure gap does decrease when we control for length of residence, it is not an additional explanation above the differing socioeconomic characteristics of homeowners and tenants. However, we have to keep in mind that our measure of length of residence is an approximation and not the actual length of residence. A better measurement could have resulted in a more significant effect, independent from other characteristics. The homeownership effect in model 1 (0.13) becomes 38% smaller (0.08) in model 5 in which we control for all three mechanisms (selection, political trust and length of residence). Although this is a significant reduction (χ²=19.01, p=0.000), the tenure gap is still positive and significant (b=0.08, p=0.000). This (again), confirms the first general hypothesis that homeownership has a positive effect on electoral participation. [Figure 1] Our second hypothesis predicted the tenure gap in electoral participation to be largest in the market-based regime, followed by the family-based regime, the rent & own-regime and the post-socialist regime, for which we predicted no effect. We summarized the predicted probabilities of homeowners and tenants, reflecting the (uncontrolled) tenure gap, in Figure 1. The gap is indeed largest in the market-based regime (b=0.21, p=0.00), followed by the family-based regime (b=0.13, p=0.00), and the rent & own-regime (b=0.11, p=0.00), and it is smallest in the post-socialist regime (b=0.003, p=0.01). The family regime and rent & own-regime are not significantly different in their tenure gap, while the other regimes differ significantly from each other. Although the effect is very small in the post-socialist regime, and was nonsignificant for the three countries separately, combined there is enough power to reach significance, although in substantive terms, the difference is hardly relevant. This confirms our second hypotheses. Our third hypothesis reads: the tenure gap differences in electoral participation between housing regimes can be (partly) explained by systematic differences in length of residence between homeowners and tenants, and by different selection into homeownership. We test this in models 3 to 5 (in Table 5). We do not discuss the main effect of our housing regimes-variable on voting, as this effect probably proxies the impact of other country-level determinants of voting (e.g. electoral system, welfare regime). In line with our hypotheses, we focus on the interaction between the housing regimes-variable, and the tenure gap in voting. At the bottom of Table 5, the tenure gap for each housing regime is shown, controlled for the variables in the model. If the number is bold, the tenure gap is significantly different from zero, while the stars indicate whether the tenure gap significantly differs from the gap in model 2. Model 3 shows that the 15 tenure gaps all become smaller when controlled for selection. The largest decreases are in the market-based regime and in the rent & own-regime, while the tenure gap in the post-socialist regime becomes nonsignificant. Also, the difference in the tenure gap between the family-based regime and the market-based regime disappears when we control for selection into homeownership. These finding are in line with our predictions, since we predicted the tenure gap to be (partly) explained by selection into homeownership, although we expected the selection-effect to be less strong in the rent & own-regime. Although the effect of length of residence is significant in model 4 (those that stay longer in the same house have a higher propensity to vote), it disappears and adds no extra explanatory power when we control for selection in model 5. Moreover, length of residence does not significantly decrease the tenure gap compared to the uncontrolled model for each housing regime. Model 5 shows the combined effect of length of residence and selection. It shows that the selection into homeownership accounts for differences in length of residence between homeowners and tenants. We can therefore only partly confirm hypothesis 2. After controlling for selection and length of residence, differences between housing regimes have diminished considerably. The tenure gap in voting became non-significant in the post-socialist regime and the differences between the market-regime and the family-regime have disappeared. However, the tenure gap – be it of a smaller size – still remains in the market-based, family-based and rent & own regime which indicates that there are other explanations necessary in order to explain the higher propensity to vote of homeowners compared to tenants. Conclusion and discussion While policy makers and politicians in Europe and the US use ‘better’ citizenship as an argument to increase homeownership, we researched if this effect actually exists. We use pre-crisis data on homeownership, voter turnout and length of residence in 18 European countries and the US to answer our research question: do homeowners and tenants differ in their electoral participation across different housing regimes, and to which extent can these housing regime differences be explained by a) selection into homeownership and b) differences between owners and tenants in terms of length of residence. Homeowners and tenants do differ in their turnout in national elections, and this effect varies considerably across countries and housing regimes. The effect is largest in the market-based regime, in which mortgaged homeownership is the standard and where there are little options in the (social) rental market, which pushes people into homeownership. The effect is smaller in the family-based regime, and rent & own-regime, which do not significantly differ from each other. There is a very small tenure gap in the post-socialist regime. Although part of the tenure gap was significantly reduced when controlling for 16 selection into homeownership, the tenure gap remained significant in most countries and differed between countries and housing regimes. At the micro-level, we first tested if the tenure gap in national electoral participation could be explained with selection, political trust and length of residence. We found that the tenure gap could partly be explained by selection, however, political trust did not change the tenure gap and length of residence only decreased the tenure gap when not controlled for selection, in other words, the differences in (our measure of) length of residence are absorbed by selection. This indicates that, although homeowners do tend to be more residentially stable, the presumed beneficial effects of a longer length of residence may really be due to other social characteristics of homeowners, which lead to higher political participation compared to tenants. It is thus possible that people with more ‘stable’ characteristics, e.g. a higher income and a higher education, tend to become homeowners but also tend to be more residentially stable in the first place, whether they own or rent. This is a novel finding, and calls into question the presumed higher sociability and participation in civil society of homeowners resulting from a firmer rooting in their local communities. After all, homeownership is often more suburban and of a more privatized, ‘inward-focused’ nature compared to renting (Kemeny, 1981; Putnam, 2001). Although our measure of length of residence was not perfect, as we will elaborate upon later, we do find a length of residence-effect which disappears after we control for selection. A better measurement could however have resulted in a stronger effect, which could have been independent of other social characteristics. Second, we tested macro-level hypotheses on the tenure gap in voting by housing regimes. We argued that housing regimes, which influence the costs and benefits of the different tenures, select people and in this case an electorate into different tenures and in different length of residences. We found that the effect as described above could only partly be explained with selection. And even though length of residence reduced the tenure gap, this effect did not hold when controlled for selection. Although others (DiPasquale & Glaeser, 1999; McCabe, 2013) found that length of residence explained a quarter till half of the homeownership-effect in the US and Germany, we did not find this to hold for nineteen countries combined. There are, at least, two possible explanations. Firstly, there is no ‘independent’ length of residence-effect. As we use different controls for selection into homeownership, the length of residenceeffect found in earlier studies is now explained. Secondly, our operationalization of length of residence was not appropriate enough because we used other data sources to impute a proxy of length of residence. Our length of residence-measurement was significant without controlling for selection. This indicates that there is a length of residence-effect, and it might have been stronger if we had a direct measure instead of a (crude) indirect measure. We were able to explain the tenure gap in the post-socialist regime completely, and in the familybased regime, the market-based regime and the rent & own-regime for about a quarter up to a half. This 17 means that there may be other explanations for the tenure gap-differences in electoral participation, although again it is possible that a more accurate measure of length of residence would have resulted in a stronger reduction of the tenure gap in voting across housing regimes. Part of the differences between countries might be attributed to differences in municipal registration for voting, which may somehow covary with the housing regime. When tenants move more often than homeowners, and they move before their voting pass arrives, this would reduce electoral participation of tenants. Although this is a possibility, other factors than the national electoral system in different housing regimes influence our outcomes, because we find the same effects in the country-fixed effects models in which the country dummies ‘control’ for all unobserved heterogeneity between countries, like aspects of the electoral system (Franklin, 2004). Also, the fact that we could hardly explain the tenure gap in the family-based regime, where Spain and Greece had the largest tenure gap in voting, indicates that other mechanisms may be at work or that we are lacking other appropriate controls. Our selection variables are limited as well as our measure of length of residence, hence we cannot rule out that the tenure gap would completely disappear if we would have perfect measurements. Another limitation of this research is causality. We cannot be sure about causality between homeownership and turnout, because we do not have longitudinal data. It is possible that people who are interested in politics and turn out in elections are more likely to buy a house. The policy implication from this research is that the expected (positive) homeownership-effect on voting in national elections is present, but that a large part of this effect is caused by selection into homeownership. As better measurements potentially would have allowed for a ‘complete’ explanation of the tenure gap, and of housing regime-differences in the tenure gap, policy-makers should be more cautious when promoting homeownership based on the argument that it turns people into ‘better citizens’ (DiPasquale & Glaeser, 1999).

Romania and Ukraine are excluded because income data are missing completely, Luxembourg is an outlier and not easily classifiable in the housing regime typology, Finland and Turkey have no length of residence-data and in Hungary there were only 78 tenants making the sample too skewed for reliable analysis. 2 The country-fixed effects analyses can be obtained from the first author. 28
