Common market

Topic: International Trade Policy, WTO and Intellectual Property · NCERT: Beyond NCERT

Meaning

A common market is a group of countries that has a customs union (no tariffs inside the group and one common tariff on outsiders) and also lets labour and capital move freely among its members. It is the fourth stage in Bela Balassa's (1961) ladder of economic integration. It matters because this is where integration moves beyond trade in goods. Workers can take jobs, and money can be invested, anywhere in the group, as if the members were one economy.

Common market = Customs union (FTA + common external tariff) + free movement of labour and capital

Explanation

Where it sits in Balassa's ladder (1961)

Bela Balassa ranked integration from shallow to deep. Each stage keeps everything from the stage before it and adds one new feature.

• Preferential trade agreement (PTA): tariffs are reduced, not removed, on an agreed list of goods (e.g. APTA, SAPTA).
• Free trade agreement (FTA): tariffs are removed on substantially all trade, but each member keeps its own tariff on outsiders (e.g. SAFTA).
• Customs union: FTA + common external tariff (CET), meaning every member charges the same duty on imports from outside (e.g. SACU, Mercosur, EU in 1968).
• Common market: customs union + free movement of labour and capital (e.g. EU Single Market, 1993).
• Economic union: common market + harmonised (made similar) fiscal, monetary and regulatory policies (e.g. EU).
• Monetary union: a common currency and a single monetary policy (e.g. Eurozone, 1999).
• Complete integration: a supranational authority (a body above national governments) runs economic policy. No example yet.

The building blocks of a common market

• Free trade inside: goods cross borders between members with no duty.
• Common external tariff: all members charge outsiders the same duty.

• So there is no need for internal rules of origin (rules that decide which country a product comes from). A good that enters any member has paid the same duty.

• Free movement of labour: a citizen of one member can live and work in another without a work permit.

• Free movement of capital: firms and savers can invest, lend and move money across member borders without controls.
• In textbook terms, the EU model is called the "four freedoms": free movement of goods, services, capital and people.

Why free factor movement matters

• Factors of production are the inputs used to make goods, mainly labour and capital.
• Labour goes where it earns more:
• workers move from low-wage members to high-wage members;
• labour shortages in the richer member ease;

• over time, wage gaps inside the group tend to narrow.

• Capital goes where it earns more:

• investors put money where returns are higher;
• capital-poor members get more investment;

• resources are used more efficiently across the whole group.

• What it demands of members: common rules on work visas, recognition of each other's degrees and licences, and open capital accounts. Members give up part of their control over borders and money flows. This is why few groups ever reach this stage.

Trade effects carry over

• Because a common market includes a customs union, Jacob Viner's (1950) effects still apply:
• Trade creation: costly home production is replaced by cheaper imports from a partner, so welfare rises.
• Trade diversion: imports shift from a cheaper non-member to a costlier partner only because the partner pays no duty, so welfare can fall.

In India

• India is not part of any common market. Its trade deals stop at the PTA or FTA stage, or at deeper "partnership" deals that still have no common external tariff and no free movement of labour.
• India's deals by Balassa stage:
• PTAs: APTA (1975, signed as the Bangkok Agreement), SAPTA (1995), India–Chile (2007, expanded 2017), India–MERCOSUR (2009).
• FTAs: India–Sri Lanka (in force 2000), SAFTA (2006), India–ASEAN TIGA (2010).

• India keeps its own tariffs on outsiders in all of these deals. That is why it needs rules of origin and CAROTAR 2020, which came into force on 21 September 2020 and puts the burden of proving origin on the importer [2].

• Some capital and services, but no free labour market:

• CEPA (Comprehensive Economic Partnership Agreement) deals such as Korea (2010), Japan (2011) and UAE (May 2022) cover goods, services, investment, IP and regulatory cooperation.
• India–EFTA TEPA (Trade and Economic Partnership Agreement): signed 10 March 2024 and in force from 1 October 2025. It has 14 chapters, including services and investment promotion [3].
• EFTA aims to raise FDI in India by US$100 bn over 15 years and help create 1 million direct jobs [3][4]. This is the first investment commitment written into an Indian FTA.

• This is an investment target. It is not the free movement of capital and labour that defines a common market.

• South Asia: SAARC's trade deal, SAFTA (2006), is still only at the FTA stage. It has no common external tariff, so it is two stages below a common market.

Don't confuse with

• Customs union: it has free internal trade and a common external tariff, but labour and capital cannot move freely. A common market adds factor mobility.
• Economic union: a common market plus harmonised fiscal, monetary and regulatory policies. A common market frees movement but does not require common policies.
• Free trade agreement (FTA): members keep different tariffs on outsiders, so an FTA needs rules of origin. A common market has one external tariff and no labour or capital barriers.
• Monetary union: this adds a common currency (e.g. Eurozone, 1999). The EU Single Market (1993) came before the euro.

Prelims Hooks

• Common market = customs union + free movement of labour and capital. It is the 4th stage in Balassa's (1961) ladder.
• Balassa order: PTA → FTA → Customs union → Common market → Economic union → Monetary union → Complete integration.
• Standard example: the EU Single Market (1993). The EU became a customs union in 1968 and the Eurozone came in 1999.
• Trap: a common market does not need a common currency or harmonised fiscal policy. Those belong to later stages.
• Trap: SAFTA (2006) is an FTA, not a common market. India belongs to no customs union or common market.
• WTO legal basis: customs unions and FTAs in goods are notified under GATT Article XXIV, and integration in services under GATS Article V [1].

Mains Points

• Why South Asia stays at the FTA stage:
• a common market needs open borders for workers and capital, plus a shared external tariff;
• political distrust, security worries and large gaps in development make this hard in SAARC;

• so SAFTA (2006) has stayed an FTA, while the EU moved from customs union (1968) to Single Market (1993).

• Gains versus loss of policy space:

• factor mobility helps workers and investment go where they are most productive;
• but members lose independent control over tariffs, migration and capital flows.

• India prefers deep but selective deals such as CEPAs and TEPA, with investment targets of US$100 bn over 15 years [3][4], rather than a full common market. This protects its policy space (freedom to set its own policies) in farming, dairy and sensitive sectors (GS-II/GS-III).

• Labour mobility as India's key ask: India has surplus labour, so the movement of workers and professionals matters more to it than to most trade partners. Even without a common market, India pushes for services and people-mobility chapters in its deals. The EU FTA (concluded 27 January 2026) mainly helps labour-intensive goods such as textiles, leather and footwear [5].
