Biased Perceptions of Inequality and Redistribution

Biased Perceptions of Inequality and Redistribution

1. Idea and Punch Line
• The public holds biased perceptions of the income distribution: it perceives the distribution as “too symmetric” and “too rich”.
• Research question: do such biased perceptions affect the political economy of redistribution in democracies?
• Relevance: standard approaches hypothesize that redistribution is more intense in democracies the more unequal the income distribution
 but these models do not perform well empirically when estimated with the actual income distribution.
• Our approach: to estimate the MR approach (and its POUM extension) using the perceived income inequality (and perceived social mobility).
• Result: this works much better; clear positive association between perceived inequality and redistribution.
2. Conceptual Framework: MR Model
Mean-to-Median Ratios (selection)
Meltzer and Richard (1981, MR): with majority-voting, the volume of redistribution increases
when inequality rises.

• Mean income separates “winners” from “losers” from redistribution; median income:

Problem with MR hypothesis: empirically not confirmed.
Potential reason: all studies are based on actual income inequality – but what matters in
politics are perceptions, not facts.
3. Perceived Income Distributions
We study the answers in 29 countries to the following ISSP question:
“In our society there are groups which tend to be towards the top and groups which tend
to be toward the bottom. Below is a scale that runs from top to bottom (10 top – 1 bottom).
Where would you put yourself now on this scale?”
Distributions emerging from the answers:
Austria
Germany
Denmark
Ireland
Canada
Spain
Israel
Switzerland
Finland
Italy
Chile
Czech Republic
France
United Kingdom
Japan
South Korea
• The same pattern holds in all 29 sampled countries
• Perceived inequality is everywhere lower than factual inequality
• More unequal countries tend to underestimate inequality more.

• OLS regressions of social quota on (perceived) inequality
• Various controls included/omitted; results are robust
• Data: ISSP for 1992, 1999, 2006-2009; controls from OECD data base; crosssectional data are used.

Perceived inequality
-
 All distributions derived from self-categorizations are “too symmetric” and “too rich”
Weighted inequality
-
Two measures of perceived inequality in a country
• Ratio of average to median value of these self-categorizations  “perceived inequality”
• Ratio of “perceived inequality” to actual mean-median ratio  “weighted ratio”
(motivation: some countries are generally more (un)equal than others which might
influence citizens’ perceptions of inequality)

5. Main Results
• Using actual inequality, MR model is rejected: negative correlation between inequality and redistribution.
• Using perceived or weighted inequality, MR model cannot be rejected: positive association between inequality and redistribution.
• For weighted inequality: positive association is highly statistically and economically significant.

6. Variation: POUM Hypothesis
Prospects of Upward Mobility (POUM): poor people believe that they/their children are likely to move upward on the economic ladder.
• POUM hypothesis: the greater upward mobility, the smaller is redistribution – poor with POUM are reluctant to vote for
redistribution.
• We show: POUM hypothesis works better empirically when based on perceived POUM (based on the hard-work question) – which
are much larger than actual POUM (based on the probability of being in a much better occupation than one’s father).
7. Discussion and Extensions
• Why is the perception of income inequality biased?  preference for symmetry; inferences from acquaintances, …
• MR/POUM model: direct democracy (majority voting on issues). How about representative democracy?
