Comparative Politics: Systems and Methods

9 min read

Comparative politics examines political phenomena across countries to identify patterns, generate explanations and test theories. It moves political science beyond country-specific description toward generalisable knowledge.

Comparative Politics

A subfield of political science that systematically studies political systems, institutions, behaviour and processes across countries to discover similarities, differences and causal relationships.

Methods of comparison

J.S. Mill's two methods (adapted by political scientists)

Method of difference (Most Similar Systems Design) — compare cases that are similar in most respects but differ on the outcome.
Method of agreement (Most Different Systems Design) — compare cases that are different in most respects but share the outcome.

Levels of analysis

Individual — voters, leaders.
Subnational — provinces, districts.
National — country-level institutions.
Cross-national — sets of countries.
System-level — international or global influences.

Approaches

Institutional — formal rules (constitutions, parliaments).
Behavioural — survey research, voting studies.
Structural-functional (Almond, Powell) — political systems perform functions (input, output, system maintenance).
Political economy — interaction of economy and politics.
Historical institutionalism — path dependence, critical junctures.
Rational choice — actors as utility maximisers.

Key Points

A case study explores a single case in depth; N=1 rich description.
A small-N comparison examines a handful of cases for in-depth contrast.
A large-N (statistical) study quantitatively analyses many cases.
Mixed-methods designs combine both for triangulation.

Political systems: classifications

Aristotle's six-fold typology

Number of rulers	Pure form (rule for common good)	Corrupt form (rule for selfish interest)
One	Monarchy	Tyranny
Few	Aristocracy	Oligarchy
Many	Polity	Democracy (in his pejorative sense)

Modern classifications

Democratic vs. authoritarian vs. totalitarian.
Hybrid regimes — competitive authoritarianism (Levitsky-Way), electoral authoritarianism.
Failed / fragile states.

Forms of government

Parliamentary

Executive (PM and Cabinet) drawn from and accountable to legislature.
Examples: UK, Pakistan, India, Australia, Canada, Germany.
Vote of no confidence can remove the government.

Presidential

President is independently elected and serves a fixed term.
Separation of powers; no fusion of executive and legislature.
Examples: USA, Brazil, Mexico, Argentina.

Semi-presidential

Dual executive: directly elected president + PM accountable to legislature.
Examples: France, Russia, Egypt, Portugal.

Comparison

Parliamentary systems offer flexibility but can produce instability with weak majorities.
Presidential systems give stability but risk gridlock (Linz: "dangers of presidentialism").
Pakistan has had both: 1962 (presidential under Ayub), 1973 (parliamentary, currently).

Electoral systems

Plurality / Majority

First-Past-The-Post (FPTP) — winner takes all in single-member districts (UK, India, Pakistan, USA).
Two-round system — runoff if no majority (France).
Alternative Vote (AV) / Instant Runoff — voters rank candidates (Australia).

Proportional Representation (PR)

List PR — voters choose party; seats allocated in proportion (Netherlands, Sweden, South Africa).
Mixed Member Proportional (MMP) — combines constituency and list seats (Germany, New Zealand).
Single Transferable Vote (STV) — multi-member districts with ranked voting (Ireland, Malta).

Trade-offs

FPTP — strong governments, but disproportionality and exclusion of minorities.
PR — fair representation but coalition government and possible fragmentation.

Duverger's law

Single-member plurality systems tend to produce two-party systems.
PR tends to produce multi-party systems.

Federalism and decentralisation

Definitions

Federal — constitutionally entrenched division of powers between national and subnational units (USA, Pakistan, India, Germany, Brazil).
Unitary — central government holds primary authority (France, Japan).
Confederation — sovereign units delegate limited powers (rare today — historical EU pre-Maastricht).

Pakistan's federalism

1973 Constitution: bicameral parliament, four provinces, federal capital, three federally administered territories.
18th Amendment (2010) — devolved 17 ministries to provinces; expanded provincial autonomy.
NFC Award — vertical revenue sharing.
Council of Common Interests (CCI) — inter-governmental coordination (Art. 153).

Comparative cases

India — quasi-federal with strong centre.
Germany — cooperative federalism.
USA — dual federalism shifting to cooperative.

Political parties and party systems

Functions of parties (Almond)

Interest aggregation.
Recruitment of political leaders.
Mass mobilisation.
Policy formation.
Government formation.

Types of party systems

One-party (China, Cuba).
Dominant-party (Japan LDP for decades, Mexico PRI).
Two-party (USA, UK historically).
Multi-party (most European democracies).
Two-and-a-half party (Germany before recent fragmentation).

Pakistan's party system

Multi-party with regional concentration: PML-N (Punjab), PPP (Sindh), PTI (urban Punjab/KP), MQM (urban Sindh), JUI-F (KP/Balochistan), ANP (KP), BAP/BNP (Balochistan), independents from tribal areas.

Political development and democratisation

Modernisation theory (Lipset, Rostow)

Economic development → urbanisation, education, middle class → democracy. Statistical association robust; causal mechanisms debated.

Crises of development (Almond, Pye)

Identity crisis.
Legitimacy crisis.
Participation crisis.
Penetration crisis.
Distribution crisis.

Huntington

Political Order in Changing Societies (1968) — rapid mobilisation without institutionalisation breeds instability.

Waves of democratisation (Huntington)

First wave — early 19th century to 1922.
Second wave — 1945-1965 (decolonisation).
Third wave — 1974 (Portugal) onwards through 1990s.

Some scholars argue we are now in a democratic recession.

O'Donnell-Schmitter

Transitions from Authoritarian Rule (1986). Liberalisation → democratisation → consolidation.

Hybrid regimes

Competitive authoritarianism (Levitsky-Way) — multiparty elections but uneven playing field.
Electoral authoritarianism — elections lack freedom and fairness.

State capacity and good governance

Indicators

Worldwide Governance Indicators (WGI) — Voice & Accountability, Political Stability, Government Effectiveness, Regulatory Quality, Rule of Law, Control of Corruption.
Corruption Perceptions Index (CPI) — Transparency International.
Bertelsmann Transformation Index.

Determinants

Rule of law.
Bureaucratic professionalism.
Civilian control of military.
Tax-collection capacity.
Service delivery.

For CSS comparative answers, present a clear analytical framework before plunging into country detail. For example, contrast Pakistan's federalism with India's by listing dimensions (constitutional structure, fiscal arrangements, language policy, emergency powers) and then comparing case by case. This earns higher marks than free-flowing description.

Pakistan in comparative perspective

Regime type — hybrid (Freedom House: "Partly Free"; EIU: "Hybrid").
Civil-military relations — pattern of military involvement (1958, 1977, 1999); doctrine of "necessity".
Federalism — significantly strengthened post-2010 but uneven implementation at the local level.
Party system — moderately fragmented; regional concentration; weak intra-party democracy.
Electoral system — FPTP for National Assembly with reserved seats for women and minorities.
Judicial activism — Supreme Court played a strong role since the lawyers' movement (2007).

These themes recur in CSS questions and require precise, comparative answers rather than vague generalisations.
