Selective Inclusion
& Colonial Legacies

Rethinking the settler-extractive distinction. Why formal institutions fail to cure inequality when access is restricted.

โ€œ

Abstract

The institutional approach to development typically classifies colonial institutions as either inclusive or extractive. This categorization is based on formal design and often overlooks how rights were distributed within societies.

This paper develops the Selective Inclusion framework. Using a new Partial Access Index (PAI) for 62 former colonies, the data reveals a Settler Colony Paradox: countries treated as benchmarks of inclusive institutions often exhibited substantial exclusion.

Beyond the
Binary Choice

Influential theories link institutional development to settlement patterns. Where Europeans settled, they supposedly established "inclusive" institutions. Where they did not, they built "extractive" ones.

The Problem: This view confuses form with access. A country can have a Supreme Court (form) that excludes 80% of the population from using it (access).

"Formal institutional strength can coexist with restricted access. Who is included matters as much as what institutions exist."

Conceptual Framework

A

Institutional Form

Does the constitution exist? Are there courts? (The standard measure).

B

Institutional Access

Can the indigenous majority vote? Can they own titled land? (The new measure).

Measuring Reality

The Partial Access Index (PAI).
A new historical dataset (N=62) constructed across four critical domains.

๐Ÿ—ณ๏ธ

Political Franchise

Was voting restricted to an elite, or was there universal suffrage?

โš–๏ธ

Legal Uniformity

Was there one law for all, or parallel "customary" courts for the poor?

๐Ÿ›๏ธ

Executive Constraints

Could the population check the leader's power?

๐ŸŽ“

Economic Access

Was education and land ownership accessible to non-elites?

Distinct from
"Democracy"

A common critique is that the Partial Access Index (PAI) is just a proxy for democracy. However, data validation against the Polity IV dataset reveals a crucial divergence.

The chart reveals the "Settler Paradox": nations that score high on standard democracy indices (Institutional Form) but low on actual access.

  • Inclusive: High Form + High Access
  • Extractive: Low Form + Low Access
  • The Paradox: High Form + Restricted Access

Empirical Findings

Higher institutional access at independence is robustly associated with lower long-term income inequality (Gini 1995-2015).

Predicted Income Inequality

Low Access Regimes 45.83

Highest Inequality (e.g., Sub-Saharan Africa)

Medium Access Regimes 44.37

Partial Inclusion (e.g., Latin America)

High Access Regimes 41.10

Lowest Inequality

Robustness

Results survive "Jackknife" resampling and region-exclusion tests. Patterns are not driven by outliers.

๐ŸŒ

Controls

The "Low Access" penalty remains significant even when controlling for colonial origin and GDP.

๐Ÿ“‰

Non-Linearity

"Partial inclusion" can generate high inequality by empowering elites while excluding the majority.

Regional Archetypes

The Trap of
Partial Reform

Why "more" institutions don't always mean "less" inequality. The data reveals two distinct paths to the same unequal outcome.

I.

The "Partial" Trap

Archetype: Latin America
44.4
Predicted Gini

The Mechanism

Reforms expanded Political Rights (voting) but restricted Economic Assets (land).

"Liberal Forms, Elite Assets" New legal institutions were used to formalize old hierarchies rather than dismantle them.

II.

The "Exclusion" Trap

Archetype: Sub-Saharan Africa
45.8
Predicted Gini

The Mechanism

Driven by Bifurcated Rule. Civil law for elites; customary law for the majority.

"Concentrated Power" Weak constraints on the executive allowed elites to capture limited economic rents.

Key Insight: Why Partial Inclusion Spikes Inequality

Inequality peaks at intermediate levels of access (Medium Access). Partial inclusion modernizes the economy enough to create wealth, but restricts the assets needed to share itโ€”widening the gap more than stagnant exclusion.
