How Property Wealth Pushed Voters to Back Brexit

Why Wealth Might Drive Votes for Change

Wealth provides household-level insurance against financial risk, which can reduce risk aversion and make voters more willing to support changes to the status quo. Jane Green and Raluca L. Pahontu apply this “wealth-as-insurance” idea to electoral behavior to explain a puzzle about Brexit: why so many Leave supporters appeared relatively well-off despite narratives that Brexit was a revolt by the economically left-behind.

The Brexit Puzzle and the Argument

The study starts from the contrast between accounts that portray Brexit as driven by economic grievance and the empirical observation that many Leave voters held substantial property wealth. Green and Pahontu argue that holding wealth (especially property) gives voters a buffer against economic shocks, lowering their risk aversion and increasing the likelihood that those who want change will vote for it.

Evidence: Panel Surveys and an Experiment

The authors test this mechanism using two panel surveys of UK respondents and a complementary survey experiment. Their empirical approach explicitly accounts for unobserved individual-level heterogeneity across waves of the panels, strengthening claims about the relationship between wealth and vote choice.

Key empirical elements:

• Two panel surveys tracking the same individuals over time to control for fixed personal characteristics.
• A survey experiment designed to probe the causal role of the proposed mechanism.

Main Findings

• Individuals with greater property wealth were more likely to support leaving the EU.
• Those who lacked wealth were less likely to back Leave, consistent with wealth operating as a form of self-insurance that reduces reluctance to embrace change.
• Results hold when accounting for unobserved individual heterogeneity in the panel data and are supported by the survey experiment.

Implications for Electoral Behavior

These findings suggest that asset ownership and wealth buffers shape risk calculations in vote choice, not just income or labor-market position. The study highlights a distinct pathway—wealth-as-insurance—through which socioeconomic status can affect support for major institutional change. This mechanism helps reconcile seemingly contradictory descriptions of Brexit voters and points to broader consequences for understanding who supports political change in other contexts.
