Regulation, competition and the cost of living in small island economies

Why expensive island economies need better market design, not just more rules

Small island economies are expensive for structural reasons. They are small, often remote and heavily reliant on imports. Land is scarce, supply chains are fragile. A small number of firms can dominate shipping, distribution, retail or housing. In places like these, regulation matters more than it does in larger economies, because it shapes who can enter a market, how quickly supply can respond and how much competition consumers can access.

That is why the debate is often framed the wrong way. The question is not whether overseas jurisdictions need more regulation or less. It is whether regulation makes markets work better. Done well, it can ease pressure on the cost of living. Done badly, it can protect incumbents, slow investment and make already expensive places harder to afford.

Why costs stay high

Three structural constraints explain much of the problem.

The first is scale. Small markets cannot support the same depth of competition as large ones. Some concentration may be unavoidable, but concentration can also become entrenched if rules, licensing or procurement make it too hard for new firms to enter.

The second is distance. Shipping delays, limited freight capacity and weak redundancy in supply chains all raise the cost of doing business. When disruption hits, there are often fewer alternatives.

The third is land. Scarcity pushes up housing costs, limits warehousing and makes it harder to expand retail or logistics capacity when bottlenecks appear.

These constraints do not make policymakers powerless, but they do mean governments need to focus on the right levers. In many overseas jurisdictions, affordability is not mainly a story of excess retail margins. It is a story of tight supply, weak contestability and upstream friction. If land is hard to develop, if import arrangements are exclusive, if licensing is slow, or if port capacity is constrained, prices will stay high no matter how much attention is paid to the final price on the shelf.

Prosperity is not the same as affordability

A comparison between French- and British-linked overseas jurisdictions points in the same direction. The lesson is not that one constitutional model is simply better than the other. It is that institutions, policy agility and market design can materially shape outcomes, especially in very small jurisdictions.

Some UK-linked jurisdictions appear to have used greater local flexibility to build specialised, higher-income economies. But that does not mean they have solved affordability. Even rich island jurisdictions often struggle with housing and essential costs. Prosperity does not automatically make life cheaper.

That matters because headline GDP can conceal real pressure on households. A jurisdiction may look successful on paper and still be painfully expensive for residents. In small island economies, the cost of living is not just a consumer issue, it is a structural one. Housing supply, land use, freight capacity, labour shortages and upstream concentration often matter more than the sticker price in a shop window.

What regulation should do

First, it should make entry easier and supply more responsive. That means faster licensing, better planning systems, clearer rules and fewer avoidable bottlenecks in transport and logistics.

Second, it should improve how markets function by increasing transparency, reducing switching frictions and enforcing competition rules credibly.

Only after that should policymakers look to direct price or margin controls, and even then with care. If supply cannot respond, price controls can suppress investment and make shortages worse.

The import pipeline deserves particular attention. In overseas jurisdictions, affordability is often shaped upstream, long before goods reach consumers. Exclusive import arrangements, concentrated wholesale networks, freight limits and zoning restrictions can all raise prices. If the policy goal is to make life more affordable, regulators need the authority and the data to examine those parts of the market, not just the final retail stage.

Better regulation, not simply more regulation

The wider lesson is simple. Good regulation in small markets is clear, quick, proportionate and enforced fairly. It gives investors confidence, lowers unnecessary barriers and helps scarce land, labour and capital move to better uses. Bad regulation does the opposite. It adds friction without adding capacity. It protects incumbents without improving service. It tries to cap visible prices without dealing with the supply problems underneath them.

Overseas jurisdictions cannot change their geography. They can, however, change how their markets work. That is why regulation matters so much. The best approach is not more rules for their own sake, nor hostility to regulation. It is better regulation: rules that expand supply, support competition and reflect the realities of island economies. In places where the margin for error is small, that can make a meaningful difference to the cost of living.
