🌐 International Barriers
- Primary product dependency.
- Deteriorating terms of trade — if export prices fall relative to import prices, a country must export more just to afford the same volume of imports.
- Trade barriers in developed countries — tariffs and subsidies in the EU/US on agricultural products shut out developing country exporters.
- Indebtedness.
- Capital flight — wealthy individuals and firms move money out of the country to avoid taxes, instability, or poor returns → reduces domestic investment.
- Unfavourable loan conditions — historically, IMF/World Bank structural adjustment programmes imposed austerity that sometimes worsened poverty in the short run.
Zambia: Zambia depends on copper for ~70% of export revenue. When global copper prices fell sharply in 2015, GDP growth collapsed, the currency depreciated, and government debt surged — illustrating the dangers of primary product dependency.
👥 Social & Human Capital Barriers
- Low levels of human capital — inadequate education and healthcare reduce productivity and innovation capacity.
- Brain drain — skilled workers emigrate, depriving their home country of trained doctors, engineers, and teachers.
- Gender inequality — when women are denied education or economic opportunities, half the potential workforce is under-utilised.
- Rapid population growth — if population grows faster than GDP, GDP per capita falls. More resources are needed just to maintain current living standards.
- Disease burden — HIV/AIDS, malaria, and tuberculosis reduce the working-age population and productivity. Healthcare costs divert spending from productive investment.
- Cultural barriers — social norms may restrict entrepreneurship, discourage female education, or perpetuate subsistence farming over commercial activity.
- Lack of access to credit — without a functioning financial system, entrepreneurs cannot borrow to start or expand businesses.
Social and economic barriers are interconnected. Poor health → low school attendance → low human capital → low incomes → poor health. Breaking any link in the chain requires targeted intervention.

⚖️ Evaluation: Which Barriers Matter Most?
Economists disagree about which barriers are most important. The answer varies by country and context.
- Institutionalist view (Acemoglu & Robinson) — institutions are the root cause. Countries with inclusive institutions (property rights, rule of law, democracy) develop; those with extractive institutions don't.
- Geography view (Jeffrey Sachs) — geography determines disease burden, trade costs, and agricultural productivity, which shape development paths.
- Dependency theory — developing countries are held back by their position in the global economic system, exploited through unequal trade and colonial legacies.
For IB essays: pick 2–3 barriers relevant to your chosen country. Explain how each barrier reduces growth/development and discuss which might be most significant. This shows analytical depth.
