What you'll learn
This topic is where the theory of trade meets the position small Caribbean economies actually occupy. Comparative advantage says specialisation and exchange raise total output. Globalisation is that argument carried to its conclusion across the world economy — and regional integration is the response of small states that find the global version does not serve them well on its own.
Globalisation is the increasing integration of national economies through trade, capital flows, technology and the movement of people. It is not a policy but a process, driven by falling transport and communication costs, liberalised trade and capital, and the rise of firms operating across many countries at once.
Regional integration is the deliberate part: countries agreeing to remove barriers between themselves, in stages running from a free trade area up to full economic and monetary union. For the Caribbean this is CARICOM and the CSME, and the gap between what has been agreed on paper and what operates in practice is itself one of the most examinable features of the topic.
The analytical core is trade creation against trade diversion. Integration is not automatically beneficial: removing tariffs between members while keeping them against everyone else can shift purchases from a genuinely cheaper world producer to a more expensive partner. Whether a union helps depends on which effect dominates, and that is an empirical question, not a matter of principle.
By the end you should be able to define globalisation and its drivers, set out the stages of integration, distinguish trade creation from trade diversion and calculate both, explain the aims and difficulties of CARICOM and the CSME, and evaluate integration for small open economies.

Core concepts
What drives globalisation
Four forces, and naming them separately is worth more than a general statement that the world has become more connected.
Falling transport and communication costs. Containerisation, air freight and near-costless communication have made distance far less of a barrier than it was.
Trade and capital liberalisation. Successive rounds of tariff reduction and the removal of capital controls have opened markets that were previously closed.
Technology. Production can be broken into stages carried out in different countries, so a single product is assembled from components made across several — the global supply chain.
Multinational corporations. Firms organising production across borders are both a consequence of the process and one of its main drivers.
The effects, honestly stated
Globalisation has genuine benefits and genuine costs, and an answer that presents only one side is incomplete regardless of which side it takes.
The benefits. Access to larger markets allows economies of scale a small domestic market could never support. Consumers gain variety and lower prices. Foreign direct investment brings capital, technology and management practice. Competition pushes domestic firms towards efficiency. And the transfer of technology can raise productivity faster than domestic development alone would.
The costs. Domestic industries may not survive exposure to larger and more efficient foreign competitors, and the adjustment falls on identifiable workers and communities. Economies become more vulnerable to external shocks — a financial crisis or recession elsewhere transmits quickly. Multinationals have bargaining power that small states struggle to match, particularly over tax and labour standards. Cultural and consumption patterns shift in ways not everyone welcomes. And a brain drain of skilled workers to higher-wage economies removes exactly the human capital a developing economy has invested in.
The distributional point is the one most often missed. Globalisation raises total output while distributing gains and losses unevenly, both between countries and within them. Saying that total output rises is not the same as saying everyone benefits, and evaluation questions turn on the difference.
The stages of integration
They form a ladder, each stage containing the one below it, and getting the order right is straightforward marks.
A free trade area removes tariffs among members, but each keeps its own external tariff. That creates a practical difficulty: goods can enter through whichever member has the lowest external tariff and move freely from there, so rules of origin are needed to police it.
A customs union adds a common external tariff, which removes that problem — and removes each member's freedom to set its own trade policy.
A common market adds free movement of labour and capital, so factors as well as goods move freely.
An economic union adds harmonised economic policies.
A monetary union adds a shared currency and a single monetary authority, which as the monetary policy topic sets out means one interest rate for members whose circumstances differ.
Trade creation and trade diversion
This is the analytical core, and the distinction is what turns "integration is good" into an argument that can be assessed.
Trade creation occurs where a union shifts purchases from a higher-cost domestic producer to a lower-cost partner. Resources move to where they are used more efficiently, consumers pay less, and welfare rises.
Trade diversion occurs where a union shifts purchases from a lower-cost non-member to a higher-cost partner, because the tariff was removed only for the partner. The consumer may still pay less than before — the tariff is gone — but the country as a whole loses, because it now buys from a genuinely more expensive producer and forfeits the tariff revenue it used to collect.
The net effect of any union depends on which dominates, and that depends on the facts: how efficient partners are relative to the rest of the world, how high the external tariff is, and how similar members' economies are. Unions between countries producing similar things divert more and create less, because there is less scope for members to supply each other more cheaply than the world can.
This is a real difficulty for Caribbean integration. Member economies are small, similar and produce overlapping ranges of goods, which is precisely the configuration in which trade creation is limited. It is not an argument against CARICOM, but it means the case for it rests more on scale, bargaining power and mobility than on classical trade gains — and saying so is the mark of a strong answer.
CARICOM and the CSME
CARICOM's aims extend well beyond trade: economic integration, coordination of foreign policy, functional cooperation in areas such as health, education and disaster response, and a common position in international negotiations.
The CSME is the deeper economic project — free movement of goods, services, capital and skilled labour, the right of establishment, and a common external tariff.
Its achievements are real. Regional institutions operate in areas no single member could sustain alone. A common negotiating position carries weight that individual small states do not have. Functional cooperation in disaster response and health is substantial. And free movement of skills, where implemented, has opened opportunities for qualified workers.
The difficulties are equally real and are the material for evaluation.
Implementation lags agreement. Measures agreed at regional level require national legislation and administration, and the gap between commitment and operation is persistent.
Similar economies limit the gains. Members produce overlapping goods, so intra-regional trade remains a modest share of members' total trade.
Unequal size creates unequal outcomes. Larger and more diversified members are better placed to exploit a single market than smaller ones, which raises the fear that gains concentrate.
Sovereignty is genuinely contested. Integration requires ceding decisions to regional bodies, and national governments answerable to national electorates are reluctant.
Free movement is politically difficult where receiving states worry about pressure on services and labour markets.
Distance and transport raise the cost of intra-regional trade in a way that does not apply to contiguous land-based groupings.
Evaluating integration for small economies
The case for integration is strongest precisely where the classical trade case is weakest.
Scale. A single small market cannot support production at efficient scale; a regional market can come closer.
Bargaining power. A bloc negotiating trade agreements or dealing with multinationals has leverage no member has alone. This is arguably the strongest argument of all for small states.
Mobility. Free movement of labour allows workers to go where work exists, and of capital to where returns are highest.
Shared institutions. Regulation, standards, disaster response and higher education can be provided regionally at a cost no single member could carry.
Against that: the classical gains are limited by similarity, implementation is slow, and deeper integration costs sovereignty and — in a monetary union — the ability to run a monetary policy suited to one's own conditions.
The defensible conclusion is that for small states integration is worth pursuing, but on grounds of scale, bargaining power and shared institutions rather than on the classical trade gains, which their similarity limits. That conclusion follows from the analysis rather than being asserted, which is what an evaluation question rewards.
Worked examples
Example 1 — Trade creation (5 marks)
Before a customs union, a country produces sugar domestically at $130 per tonne. A partner country can produce it at $120, but a 40% tariff raises the partner's price to $168, so the country buys domestically at $130.
The union removes the tariff between members. The partner's sugar now costs $120, so buyers switch from the domestic producer.
This is trade creation. Production has moved from a producer costing $130 to one costing $120, a saving of $10 per tonne, and resources released domestically can be used elsewhere. Welfare rises.
Example 2 — Trade diversion (5 marks)
Take the same union, but now a non-member can produce the sugar at $100 per tonne.
Before the union, the tariff applied to everyone: the non-member's price was $100 + 40% = $140 and the partner's was $168, so the country still bought domestically at $130.
After the union, the partner is tariff-free at $120 while the non-member still faces the tariff at $140. Buyers switch to the partner.
Consumers pay $120 rather than $130, so they gain $10. But the country is now buying from a producer costing $120 when the world's cheapest costs $100 — a real resource loss of $20 per tonne relative to the efficient source. That is trade diversion.
The net effect on the country combines the creation gain against the diversion loss, and which dominates is an empirical question about the relative costs of partners and the rest of the world.
Example 3 — Why the tariff level matters (4 marks)
Suppose the external tariff had been 10% rather than 40%.
The non-member's price would have been $100 + 10% = $110, cheaper than both the domestic $130 and the partner's $132. The country would already have been importing from the cheapest world producer.
The union would then shift purchases from a $100 producer to a $120 partner — pure trade diversion, with no creation at all.
The general result follows: the higher the external tariff before the union, the more scope for trade creation; the lower it was, the more the union simply diverts. A country already trading fairly freely with the world has less to gain from forming a union and more to lose.
Example 4 — Why similarity limits the gains (4 marks)
Consider a union between economies producing largely the same goods — sugar, bananas, tourism services.
Trade creation requires a partner able to supply something more cheaply than the domestic producer. Where members produce the same range at similar costs, there is little of that, so creation is limited.
Meanwhile the common external tariff still shifts some purchases away from cheaper non-members, so diversion continues to operate.
That is the structural difficulty for Caribbean integration, and it is why the case for CARICOM rests principally on scale, bargaining power and shared institutions rather than on classical trade gains. The argument is not weaker for that — it is simply a different argument, and identifying which one applies is the analysis.
Example 5 — Free movement and the brain drain (4 marks)
A common market allows skilled workers to move freely to wherever wages are highest.
For the receiving economy this raises the supply of skilled labour and output. For the individual worker it raises income, and remittances flowing home are a credit in the sending country's secondary income.
For the sending economy the effect is more complex. It has borne the cost of educating the worker and loses the return, and where the workers leaving are teachers, nurses or engineers the loss falls on services the economy most needs.
So free movement raises total regional output while redistributing it, and a sending economy can be worse off even as the region gains. That combination — a net regional gain with a possible national loss — is exactly the kind of judgement an evaluation question is testing, and remittances partly but rarely fully offset it.
Common mistakes and how to avoid them
Treating globalisation as a policy. It is a process driven by costs, technology and liberalisation.
Assuming integration is automatically beneficial. Trade diversion can outweigh trade creation.
Confusing creation with diversion. Creation replaces a higher-cost domestic producer; diversion replaces a lower-cost non-member.
Getting the stages out of order. Free trade area, customs union, common market, economic union, monetary union.
Forgetting the common external tariff defines a customs union. A free trade area leaves each member its own.
Saying globalisation benefits everyone. It raises total output while distributing gains unevenly within and between countries.
Ignoring implementation. CARICOM measures agreed regionally frequently await national legislation.
Presenting free movement as costless to sending countries. The brain drain removes human capital the economy paid for.
How this links to your Internal Assessment
Regional trade data is published, and the strongest Internal Assessments on this topic test a specific claim rather than surveying integration in general.
Intra-regional trade as a share of members' total trade is measurable over time, and it speaks directly to how much integration has actually changed trade patterns. A share that has moved little despite decades of agreement is a finding worth explaining.
If you examine a particular good, try to identify creation and diversion separately. Comparing the partner's price with both the domestic cost and the world price is exactly the Example 2 structure, and applying it to a real product is genuine analysis.
Where you study free movement, look at both directions — skilled workers leaving and remittances arriving — rather than only one. A sending economy's position depends on the balance.
Be careful attributing changes to an agreement. Trade flows respond to world prices, exchange rates and income at the same time, and agreements are implemented gradually. The accurate claim is that the evidence is consistent with your explanation.
Exam technique for globalisation and regional integration
For creation and diversion, always state three prices: the domestic cost, the partner's cost, and the non-member's cost. The comparison cannot be made without all three, and answers giving two reach a confident wrong conclusion.
List the stages of integration in order and say what each adds to the one before. It is quick, it is precise, and it earns marks reliably.
When discussing CARICOM, separate aims, achievements and obstacles. An answer mixing them reads as a list of assertions; an answer separating them reads as an assessment.
Give both sides of globalisation. Examiners are explicitly looking for balance, and an answer arguing only the benefits or only the costs is capped regardless of how well written it is.
Command words follow the pattern. Define globalisation wants the integration-through-trade-investment-technology-migration idea. Distinguish between a free trade area and a customs union wants the common external tariff. Explain trade diversion wants the lower-cost non-member displaced by a tariff-free partner. Discuss the benefits of CSME membership wants scale, bargaining power, mobility and institutions. Evaluate regional integration for small economies wants the similarity problem, implementation difficulties and sovereignty costs against those benefits, then a conclusion.
Where the context is Caribbean, the similarity of member economies, the implementation gap and the bargaining power argument are the three points that carry the most credit.
Quick revision summary
- Globalisation is a process, driven by falling transport and communication costs, liberalisation, technology and multinationals.
- Benefits: scale, variety, lower prices, FDI, technology transfer, competitive pressure.
- Costs: exposure of domestic industry, vulnerability to external shocks, MNC bargaining power, cultural change, brain drain.
- It raises total output while distributing gains unevenly — between countries and within them.
- Stages: free trade area → customs union (adds a common external tariff) → common market (adds free movement of labour and capital) → economic union (harmonised policy) → monetary union (shared currency).
- Trade creation: a higher-cost domestic producer replaced by a lower-cost partner — welfare rises.
- Trade diversion: a lower-cost non-member replaced by a higher-cost partner — welfare falls.
- Worked case: domestic $130, partner $120, non-member $100 with a 40% external tariff — creation saves $10, diversion loses $20 against the efficient source.
- The higher the external tariff before the union, the more scope for creation; a low tariff means the union mostly diverts.
- Unions between similar economies create little and divert more — the structural difficulty for CARICOM.
- CSME provides free movement of goods, services, capital and skilled labour plus a common external tariff.
- CARICOM obstacles: implementation lagging agreement, similar economies, unequal member size, sovereignty, transport costs.
- The case for small-state integration rests on scale, bargaining power and shared institutions more than on classical trade gains.
- Free movement raises regional output but can leave a sending economy worse off, with remittances only partly offsetting.
