Unused votes and representational inequality: Evidence from a natural experiment
This paper utilizes a natural experiment in Schleswig-Holstein to demonstrate that both the number of votes allocated per voter and higher levels of social deprivation significantly increase the proportion of unused votes, thereby exacerbating representational inequalities.

Imagine you are at a buffet where the rules say: "The bigger your table, the more plates of food you get to take." If your table seats four people, you get four plates. If your table seats seven, you get seven plates.
Now, imagine that some people at the table only take three plates, even though they are allowed to take seven. They leave the other four plates empty. In the world of voting, these empty plates are called "unused votes."
This paper by Jona-Frederik Baumert is a detective story about why these empty plates happen in local elections in a German state called Schleswig-Holstein. Here is the simple breakdown of what the author found:
1. The Mystery of the Empty Plates
In many elections, you only get one vote. But in some local elections in Germany, you get multiple votes (sometimes up to seven). The goal is to let you choose more candidates.
However, the author noticed something strange: The more votes you are allowed to cast, the more votes you tend to leave unused.
- The Analogy: Think of it like a video game controller with extra buttons. If you are used to a simple remote with just "On" and "Off," and someone hands you a complex controller with 20 buttons, you might get confused or forget to press them all. You end up using only a few, leaving the rest untouched.
- The Finding: The study found that for every extra vote a voter is allowed to cast, the number of unused votes goes up by about 1.5% to 2.9%. So, if you have 7 votes instead of 2, you are much more likely to leave some on the table.
2. The "Natural Experiment" (The Magic Line)
How did the author prove this? He used a clever trick called a Regression Discontinuity Design.
- The Analogy: Imagine a school that gives out free ice cream. The rule is: "If you are 10 years old or younger, you get 2 scoops. If you are 11 or older, you get 5 scoops."
- The Setup: A child who is exactly 10 years and 11 months old gets 2 scoops. A child who is exactly 11 years and 1 month old gets 5 scoops. These two kids are almost identical in every way (same school, same neighborhood, same parents), but they get a very different number of scoops because of a tiny difference in age.
- The Study: In Schleswig-Holstein, the number of votes you get depends on how many people live in your town. There are "magic lines" (population thresholds).
- Towns with 2,500 people get 7 votes per voter.
- Towns with 2,501 people get only 3 votes per voter.
- These towns are neighbors and are almost exactly the same, but the voters in the slightly smaller town get more votes.
- The Result: By comparing these nearly identical towns, the author could see that the extra votes in the smaller towns directly caused more unused votes. It wasn't because the people were different; it was just because they had more buttons to press.
3. The "Tired Voter" Factor (Social Deprivation)
The paper also looked at who leaves the votes unused.
- The Finding: The study found that in areas with higher social deprivation (places with more poverty, lower income, or lower education), people left more votes unused.
- The Analogy: Think of voting like filling out a long, complicated form. If you are stressed, tired, or didn't go to school long enough to feel confident with forms, you might just fill out the first few lines and give up. The author used voter turnout in national elections as a "thermometer" for this stress. In places where fewer people showed up for national elections, more votes were left unused in local elections.
4. Why Does This Matter?
The author argues that "unused votes" are a hidden problem.
- The Problem: We usually worry about "spoiled" ballots (where you mess up and the vote is thrown away). But "unused" votes are actually much more common.
- The Consequence: If people in poorer neighborhoods leave more votes unused, their voices are heard less than people in richer neighborhoods. This creates an inequality. It's like a group project where some members do all the work and others just sit there; the final result doesn't truly represent everyone's opinion.
Summary
The paper concludes that:
- More choices can be confusing: When voters are given more votes to cast, they often don't use them all, likely due to habit or confusion.
- Poverty plays a role: People in more disadvantaged areas are more likely to leave votes unused.
- The system has a flaw: Because the number of votes changes based on town size, some people are accidentally given a harder voting task than their neighbors, leading to unequal representation.
The author suggests that if we want every person's voice to count equally, we might need to rethink how many votes we give people or how we explain the system to them.
