Their results provide evidence that people in Europe are negatively affected by income inequality, whereas reduction of inequality has a positive effect on well-being. Since the authors simultaneously estimate the effects of income inequality and its reduction, their results might indicate that not only the outcome (inequality), but also the procedure (redistribution) that leads to the outcome influences subjective wellbeing. Their results also show that the positive effect of redistribution is stronger for less affluent members of the society and left-wing oriented individuals. While post-government inequality seems to have no significant effect in Western Europe, its impact is negative and highly significant in Eastern Europe.

www.economics-ejournal.org 1 1 Introduction Inequality and redistribution are important topics in social sciences. Numerous studies have examined the impact of income inequality on various adverse societal outcomes, and concluded that inequality is positively associated with crime (Choe 2008; Fajnzylber et al. 2002; Scorzafave and Soares 2009) and working hours (Bowles and Park 2005), negatively with health (Kaplan et al. 1996; Wilkinson and Pickett 2006), trust (Gustavsson and Jordahl 2008; Knack and Keefer 1997), political engagement (Horn 2011, 2008, 2010) and mobility (Corak 2013; Wilkinson and Pickett 2009).1 In the presence of upward social comparison, greater inequality also means greater discrepancy between the aspirations and actual incomes of less wealthy individuals, which imposes substantial psychological costs on these people (Frank 2007).2 The relationship between these outcomes and subjective well-being (Dolan et al. 2008; Frey and Stutzer 2002) predicts that income inequality should relate negatively to well-being. Besides, inequality may also shape subjective well-being directly, not only through these channels. Humans are social animals; we can empathize with other people’s misery, which means that high inequality may reduce our happiness even without further societal effects. Besides, the negative effect of inequality may result from the envy of the poor.3 Starting with Morawetz et al. (1977), inequality has been the topic of several empirical papers. Studies using panel, time-series and within-country data document mostly negative effects in Europe (Alesina et al. 2004; Ferrer-iCarbonell and Ramos 2010; Grosfeld and Senik 2010; Hagerty 2000; Schwarze and Härpfer 2007; Winkelmann and Winkelmann 2010), and in other nonEuropean countries as well (Oishi et al. 2011; Oshio and Kobayashi 2010).4 _________________________ 1 For a review, see Wilkinson and Pickett (2009, 2010). 2 In the social comparison literature range-frequency theory also predicts that increasing inequality affects well-being negatively (Hagerty 2000). 3 However, a recent empirical paper found that the relationship between preference for a more equal society and envy is very weak (Kemp and Bolle 2013). 4 Cross-sectional cross-country or pooled cross-sectional analyses without controlling for the cultural background of countries are inconclusive. Berg and Veenhoven (2010) and Helliwell and Huang (2008) found a positive association between income inequality and well-being, whereas in an analysis of European countries Fahey and Smyth (2004) reported a negative relationship.

However, the effect varies with the sample: in Europe income inequality negatively affects well-being. Determinants of preferences for redistribution are discussed in detail in the literature. There are several factors that have been shown to play an important role: self-interest (income and expected social mobility), risk-aversion (history of misfortune), altruism, culture and ideology, social impact of inequality, acceptable level of inequality, and perception of fairness (Alesina and Giuliano 2011; Alesina and La Ferrara 2005; Corneo and Grüner 2002; Fong 2001; Luttmer and Singhal 2011). Although societal impacts of inequality, determinants of preferences for redistribution, and the relationship between income inequality and subjective wellbeing are thoroughly studied, there is little empirical evidence about the impact of inequality reduction (redistribution)6 on well-being. Only one paper deals explicitly with the question whether the reduction of inequality by taxes and transfers can undo this negative impact. Schwarze and Härpfer (2007) studied how inequality and redistribution (reduction of inequality by the state) is associated with subjective well-being in Germany. Using the German Socio-Economic Panel they found that income inequality calculated on the regional-level has a negative effect on individual life satisfaction, but redistribution is not a significant determinant of well-being. Some redistribution-related issues were analyzed by other papers. Di Tella et al. (2003) and Di Tella and MacCulloch (2008) estimate the effect of unemployment benefits (defined as the income replacement rate) on subjective well-being. Although unemployment benefits are only one component _________________________ 5 Note however, that the impact of income inequality may be different in some cases. In an unpredictable, volatile environment inequality may be perceived as a signal of increased opportunities and may affect satisfaction positively (Hirschman and Rotschild 1973). For empirical evidence from the Eastern European transition, see Grossfeld and Senik (2010). They show that in the early transition period inequality was positively associated with satisfaction in Poland, but after a couple of years the relationship became negative. 6 In this paper we regard ‘inequality reduction’ and ‘redistribution’ as identical. Unless noted otherwise, ‘redistribution’ and ‘inequality reduction’ refer to the reduction of income inequality by government tax and transfer policies.
www.economics-ejournal.org 3 of redistribution, we can take it as a proxy variable of the reduction of inequality. These papers show that a generous welfare state is positively correlated with satisfaction. Oishi et al. (2012) using 54 countries from the Gallup World Poll have found that progressive taxation is positively associated with a global-lifeevaluation index. In this paper we enrich the existing knowledge about the association of inequality reduction by governmental taxes and transfers (redistribution) with subjective well-being. The novelty of our paper is that it is the first to estimate the effect of inequality and the reduction of inequality simultaneously, not limited to an individual country, but using data from several European countries. The analysis is based on the first four waves of the European Social Survey. We simultaneously analyze how inequality and redistribution affect life satisfaction. Our results corroborate the findings of previous literature that – controlling for personal characteristics of the respondents, GDP, unemployment and inflation rate, country fixed effects and year fixed effects – people in Europe are negatively affected by income inequality, whereas provide new evidence that inequality reduction has a positive impact on well-being. Moreover, the simultaneously estimated effects of inequality and its reduction might indicate that it is not only outcome (net income inequality) that influences subjective well-being but also the procedure (redistribution) that leads to the outcome has a relevant impact. We propose four theoretical interpretations of these empirical results. We suggest that the poor may feel more protected, whereas the rich may feel more generous because of higher level of inequality reduction by taxes and transfers, which may result in an emotional benefit for them. It is also possible that not only actual but also perceived inequality is associated with well-being. Another explanation might be that the reduction of income inequality correlates with the generosity of the welfare services provided by the state, and the high level of our redistribution variable might capture a low level of other dimensions of social inequality possibly increasing life satisfaction. However, according to our findings, there is some heterogeneity in the effects. In line with the previous literature on determinants of preferences for redistribution, we find that the positive effect of redistribution is stronger among less affluent members of the society, and left-wingers. Income inequality has no significant effect in Western Europe, but its impact negative and highly significant in Eastern Europe.
www.economics-ejournal.org 4 Our paper is structured as follows. The next section describes the data and the estimation methods we used. Section 3 shows the estimation of regression models. Section 4 concludes. 2 Data and Methods Our main data source is the four waves of the European Social Survey (ESS). ESS is a repeated cross-sectional survey from every other year. The first wave started in 2002, the fourth wave was launched in 2008. We include in our analysis only those 29 countries that participated in more than one round.7 Our analysis relies on a self-reported measure of well-being. In the ESSquestionnaire everyone is asked the following single-item question: “All things considered, how satisfied are you with your life as a whole nowadays?” They answer the question on an 11-point scale (0 – extremely dissatisfied, 10 – extremely satisfied). This global life evaluation is our dependent variable. We estimate a linear relationship between inequality reduction and satisfaction, using the following specification: icttcictct N ctctict PCIRS ελµγββββ +++++++= 3210 (1) where ict S is the life satisfaction of individual i, who lives in country c in time (wave) t. ct R is the measure of inequality reduction, N ct I is post-government (net) income inequality, ct C is the vector of country-level variables, ict P is the vector of personal characteristics of individual i. We also include a country fixed effect i µ and a wave fixed effect t λ . Finally, the equation includes the usual error term ( ict ε ). In line with the literature, this paper measures income inequality by the Gini coefficient. The source of the inequality data is the Standardized World Income Inequality Database (Version 3.0), which provides Gini indices of gross and net income inequality for more than 100 countries (Solt 2009). Data of gross and net income inequality allow us to calculate the effect of government taxes and transfers on income inequality. This index of income inequality reduction by _________________________ 7 The list of participating countries by ESS rounds is given in Table A1 in the appendix.
www.economics-ejournal.org 5 governmental taxes and transfers is computed as the difference between Gini indices based on gross and net incomes divided by gross income inequality: 100⋅ − =G ct N ct G ct ct I II R (2) where ct R is income inequality reduction by governmental taxes and transfers in country c in time t (in percent), G ct I is the pre-government (gross) income inequality and N ct I is the post-government (net) income inequality. The inequality reduction index shows the percentage reduction in inequality by government tax and transfer policies. In other words, it measures the extent of change in income distribution due to governmental taxes and money transfers. This means that our inequality reduction variable captures policies that affect net income distribution, but set aside redistribution related policies that do not change net income inequality (e.g. in-kind transfers to the poor). Since Gini indices are calculated on the basis of surveys, measurement error is inevitable. If the variance of Gini indices and inequality reduction is mostly due to measurement errors rather than actual change, then our estimates would be biased. We try to mitigate this bias by calculating the trend values of the time series which capture long-term changes and set aside short-term fluctuation (which is supposed to be primarily the result of the measurement errors). Using inequality reduction and income inequality data for the last two decades, we compute trend components of inequality and its reduction for every country with the Hodrick-Prescott filter (Hodrick and Prescott 1997), and we merge these trend values to the country-wave observations.8 The Gini index is highest in Russia, while lowest in Sweden and Denmark. The reduction of inequality (redistribution) is high in the Scandinavian countries, Germany, and Austria and low in Russia, Ukraine, and Bulgaria.9 Our other country-level right-hand side variables are the welfare of the states measured by Gross Domestic Product, unemployment rate, and inflation. Data on GDP per capita come from the World Bank (PPP, constant 2005 international $). In our analysis we use it in logarithmic form because of the presumed declining _________________________ 8 To extract the trend from the time series of inequality and redistribution, we used the HodrickPrescott filter with a parameter value of 6.25 as proposed by Ravn and Uhlig (2002) for annual observations. 9 Table A2 in the appendix provides descriptive statistics by country.
www.economics-ejournal.org 6 marginal effect of income. Previous research has highlighted that each doubling of GDP per capita is associated with a constant increase in average well-being (Stevenson and Wolfers 2008, 2013). Data on unemployment and inflation rate come from the World Bank as well. The control variables in our baseline regression are the following: gender, age, age squared, education (four categories), living with a partner, labor force status (seven categories), subjective health status (five categories), domicile (four categories), household size and equivalent household income. Since income comparison is an important determinant of subjective well-being (Clark et al. 2008) and GDP per capita already captures the effect of the society’s average income, we include equivalent household income as the percentage of average equivalent household income in country c in time t. With this procedure we can control for the relative income effect. We exclude some countries from the fourth wave because of missing Gini indices,10 and individuals with missing life satisfaction. The final sample contains 179,273 individuals and 94 country-time observations. We estimate OLS regressions using ESS design weights for adjusting the unequal inclusion probabilities within countries combined with another weight whose goal is to transform every sample’s N equal. In this way each crosssectional sample counts as the same in the analysis. The standard error estimates are robust to heteroskedasticity and clustered at the country-wave level.11 3 Results Table 1 shows our baseline result. We find that redistribution and post-government income inequality are significant determinants of satisfaction with life. As we expected, the coefficient on inequality is negative: people in Europe dislike inequality. The coefficient on inequality reduction has a positive sign: Inequality reducing governmental policies are correlated positively with satisfaction. The size _________________________ 10 These countries are Austria, Switzerland and Ukraine. 11 Table A3 in the appendix provides descriptive statistics of the main variables.

Or in terms of per capita GDP change: a 1 percentage point increase in redistribution is equivalent to a 2.7 percent increase in GDP, whereas a 1 point increase in the Gini index is equivalent to a 3.8 percent decrease in GDP.12 _________________________ 12 The estimated coefficient of income inequality in the previous literature is influenced by the wellbeing measure and the sample as well, thus, most of these findings are not directly comparable with our result. Ferrer-i-Carbonell and Ramos (2010) found that a 1 percentage point increase in the postgovernment Gini index results a 0.055 decrease in life satisfaction (on an 11-point scale) in Germany (1997–2007). Schwarze and Härpfer (2007) found that a similar increase in the post-government Gini index is associated with a 0.036-0.048 lower life satisfaction (on an 11-point scale) in West-Germany (1985–1998). According to Alesina et al. (2004) a 1 percentage point increase in the Gini index decreases the proportion of ‘‘very satisfied’’ people by 0.55 percentage point and increases the proportion ‘‘not very/at all satisfied’’ people by 0.53 percentage point in Western Europe (1975–
www.economics-ejournal.org 14 subsamples and different types of individuals. We presume that association between inequality reduction and satisfaction should be stronger in some groups (Eastern Europe vs. other countries, richer vs. poorer individuals, left-wingers vs. right-wingers, the formerly unemployed vs. the never unemployed). After creating binary indicator variables for these groups, we analyze heterogeneity by regressing life satisfaction on redistribution and income inequality interacted with the relevant indicator variables. Each panel in Table 4 (from A to E) represents an OLS regression where the main effects of inequality and inequality reduction are excluded, but their interaction terms with the indicator variables are included.19 For example, in Panel A (Eastern Europe vs. other countries) one set of interactions measures the effect of inequality and its reduction in post-communist countries, and another set of interactions measures the effect of inequality and its reduction in non-post-communist countries (four interactions altogether). In this way, we can directly see the effect (and the significance) of redistribution and inequality among the examined groups of individuals. We also report the p-value on the test of equal redistribution/inequality coefficients.20 Those living in post-communist countries are more likely to support the reduction of income inequality (Alesina and Fuchs-Schündeln 2007; Corneo and Grüner 2002), so we can conjecture that the effect of inequality and its reduction are stronger in former communist countries. The dissimilar historical background might be able to explain these differences (Alesina and Fuchs-Schündeln 2007). The decades of heavy state intervention might have a long-lasting impact on preferences: people in Eastern Europe may consider redistribution as more favorable and prefer a more equal society. An alternative explanation could rely on the different perceptions of opportunities. If individuals in post-communist countries believe that existing income inequalities are not caused by effort and hard work but rather by luck or connections, then they “suffer” more from inequality. Panel A shows that income inequality is not a significant determinant _________________________ 19 The regressions also include the baseline control variables and the relevant indicator variables. 20 The difference between the two coefficients is identical to the coefficient on the interaction term that would be estimated if the main effect (e.g. inequality reduction) and an interaction term (e.g. inequality reduction interacted with Eastern Europe in Panel A) would be included in the model. The p-value is identical to the p-value on the interaction term in such a model.

The coefficient on inequality reduction in post-communist countries is almost twice as high as in other countries, but this difference just barely fails to be significant at the 10 percent level. Napier and Jost (2008) present evidence that conservatives are happier than liberals partly because of their greater tolerance of inequality. Alesina et al. (2004) report that inequality has a more negative effect on the happiness of European leftists. In line with these papers, we find that the effect of redistribution is considerably weaker among individuals with right-wing orientation. On the contrary, the estimated coefficient on income inequality is statistically equal among individuals with left-wing and right-wing orientation (Panel B).21 Self-interest naturally influences preference for redistribution: wealthier individuals support less redistribution (Alesina and Giuliano 2011; Alesina and La Ferrara 2005; Molnár and Kapitány 2006; Rainer and Siedler 2008) and are more likely to be unaffected by inequality (Alesina et al. 2004; Oishi et al. 2011). In Panel C we see that those with above average household incomes gain smaller satisfaction from inequality reduction than individuals with below average household incomes, whereas the estimated coefficients on inequality are not different statistically between the two groups. On the other hand, it is not only actual income (or income rank) that influences how people react to inequality and redistribution, but perceived income matters as well (Cruces et al. 2013). In Panel D we measure individuals’ material welfare with a subjective indicator: Do they feel that their family lives comfortably on their present income? These estimates show that inequality reduction has a weaker effect on respondents who said that they live comfortably on their present income than on those with lower standards of living, whereas we cannot reject the hypothesis of equal income inequality coefficients. The positive coefficients on inequality reduction in Panel C and Panel D are in line with the hypothesis that the poor might feel more protected _________________________ 21 We consider as a left-wing oriented individual who on an 11-point left-right scale denotes value 0–4, and as a right-wing oriented individual who denotes value 6–10. Individuals choosing value 5 are coded as central orientation. In the regression beside the reported interactions we also include the interaction of inequality/inequality reduction with this central orientation dummy. It turns out that centrist individuals are affected by inequality and redistribution more than right-wingers, but less than left-wingers.
www.economics-ejournal.org 17 and the rich might feel more generous when inequality reduction happens to be higher. There is evidence that people with previous misfortune are more favorable to redistribution (Alesina and Giuliano 2011; Alesina and La Ferrara 2005). As noted by e.g. Alesina and La Ferrara (2005) the experience of unemployment may increase risk aversion or lead to sympathizing with poorer members of society, which means that inequality and redistribution should have a more considerable effect on individuals with such experiences. Panel E shows, however, individuals who have ever been unemployed for a period of more than three months are equally affected by inequality and inequality reduction, compared to those without such unemployment experience. 4 Conclusion The objective of this paper has been to examine the association of income inequality and its reduction by government taxes and transfers (redistribution) with individual’s subjective well-being. Using 1–4 waves of the European Social Survey (2002–2009), we have estimated the association of inequality and inequality reduction with life satisfaction. Our results are in line with the former evidence that income inequality is negatively related to well-being. The novelty of our analysis is the clear evidence that income inequality reduction has a positive effect on individual life satisfaction. This result contradicts the findings of Schwarze and Härpfer (2007), who found no relationship between regional-level redistribution and individual’s well-being in Germany. This discrepancy might be caused by the different samples and the differences of the measurement-level of the Gini index and redistribution. Previous papers on preference for redistribution and inequality aversion predict that the effect of inequality and its reduction is different in post-communist and in non-post-communist countries. Our results show that income inequality is not a significant determinant of well-being in Western European countries, whereas its effect is strong in Eastern Europe. Political orientation and self-interest seems to moderate the effect the inequality reduction: poorer members of society and leftwing oriented individuals seem to be more affected by inequality reduction.
www.economics-ejournal.org 18 Since we have simultaneously estimated the effects of inequality and its reduction, our results suggest that subjective well-being is influenced not only by the outcome (income inequality), but also by the procedure (redistribution) leading to the outcome. Individuals (especially the poor) may feel more protected because of higher level of inequality reduction by taxes and transfers; they may get the sense that the community will help them in hardship, irrespective of the actual inequality. We have listed three other hypotheses to explain this result. It is possible that it is not (or not only) actual but also perceived income inequality is associated with well-being. If perceived inequality is negatively correlated with extent of redistribution, then this relationship might be reflected in the positive coefficient on inequality reduction. A positive correlation between inequality reduction and the generosity of the welfare services provided by the state might mean that high level of our redistribution variable might capture low level of other dimensions of social inequality. This could increase life satisfaction. Finally, people may also feel themselves more generous because of a higher extent of inequality reduction, which may result emotional benefit for them. Further researches are needed to verify or falsify these explanations. Acknowledgement: We are grateful to Márton Medgyesi and Béla Janky for their detailed comments.
