IB Economics 10 Roadblocks to Prosperity

Why Do Some Countries Stay Poor? The 10 Barriers to Economic Growth and Development

Target Question:

What are the main barriers to economic growth and development in IB Economics?

The Snakes and Ladders Economy

You probably know the Snakes and Ladders game from your childhood. Great game. It is also a deeply unfair game. You can be three squares from the finish and almost there, roll the dice, and land on a snake that sends you spiralling back to the beginning. Luck must be involved if you are to win.

Now imagine that snake and ladders board is the global economy. Some countries are born near the top - good geography, functioning institutions, educated workforces, easy access to capital. Others start near the bottom and keep landing on snakes. Not because their people are less talented, less hardworking, or less ambitious. But because the board works against them.

That's what this IB Economics Unit and blog entry is really about. It is not just about knowing which countries are rich and which are poor and why - it is about understanding why the snakes are where they are. In this entry, we're going through all the snakes available.

Barrier 1: Rising Economic Inequality

Imagine a country that grows its economy at 6% a year for a decade. Sounds good on paper, right? GDP is up, exports are booming, the government is happy. But look a bit closer. Where is that growth actually going? Are income and resources properly distributed?

If the answer is "mostly to the top 10% of earners," then GDP growth is doing very little for the people at the bottom. And that's the core problem with economic inequality as a barrier to development.

Economic inequality:

Economic inequality measures the differences in income and wealth within a country and how these resources are distributed among members of society.

When a wealthy minority holds most of a nation's income, GDP growth simply doesn't translate into better lives for the majority. No access to education. No access to healthcare. No access to capital. The poor stay poor, even when the GDP number improves.

What would be the solution to this?

Progressive taxation - taxing higher earners at higher rates and redistributing that revenue to fund public services and welfare. In theory, it could work. In practice, this would be very difficult to achieve in many ELDCs, where tax systems are inefficient, enforcement is weak, and corruption diverts funds somewhere else before they reach the people who need them.

IB Economics Real-life example: Brazil is a great example. Despite being the world's eighth largest economy by GDP, Brazil has one of the highest Gini coefficients in the world - a measure of income inequality where 0 is perfect equality and 1 is total inequality. Brazil sits around 0.53. This is mainly why millions of people live in favelas within staring daily at gleaming skyscrapers. Growth without distribution is not economic development.

Barrier 2: Lack of Infrastructure and Appropriate Technology

Quick question: what do London, New York, Singapore, and Shanghai all have in common, apart from very expensive coffee?

They all have world-class infrastructure. Roads, ports, airports, broadband, energy grids, hospitals, schools. The physical backbone that makes any activity, economic activity included, possible.

Infrastructure:

Infrastructure includes the physical structures and facilities necessary for a country's smooth operation - transport, telecommunications, healthcare, education, utilities, and energy.

Infrastructure is the term for all of this - the essential physical structures and facilities a country needs to function. And its impact on development cannot be stressed enough. Strong infrastructure boosts productivity, attracts foreign direct investment (FDI), and enables both domestic and international trade.

In many ELDCs, infrastructure is chronically underdeveloped. Roads are obstructed in rainy seasons. Power cuts are a daily reality. Broadband is a luxury. And the knock-on effects are severe: without reliable electricity, children can't study after dark, hospitals can't run equipment, and businesses can't operate at scale.

The technology gap ass to this. When production is labour-intensive, inefficient, and reliant on outdated methods, productivity stays low - and multinational corporations have no choice but to look elsewhere to invest.

IB Economics Real-life example: Ethiopia's investment in the Grand Ethiopian Renaissance Dam - Africa's largest hydroelectric project - is a live example of infrastructure investment attempting to break a development bottleneck. When complete, it aims to provide electricity to millions of Ethiopians currently without power, and it is directly addressing one of the most fundamental infrastructure gaps holding back the country.

Barrier 3: Low Levels of Human Capital

Let's think about this for a second. You have two factories. One has state-of-the-art machinery but an undertrained workforce. The other has an incredibly skilled, healthy, educated team using basic equipment. Which one do you think is more productive?

Usually, the second one. Because human capital - the collective skills, knowledge, health, and capabilities of a workforce - is the engine of productivity. And in many ELDCs, that engine is seriously underpowered.

Low levels of human capital originate from two interconnected problems: insufficient access to education and inadequate healthcare. Without education, workers can't develop the skills modern economies demand. Without healthcare, they can't work productively even if they have skills.

The UN's Sustainable Development Goals place education and health at the heart of the development agenda because of this. And UNICEF's research adds a particularly powerful dimension: educated women are at least twice as likely to motivate their children to pursue primary education. That's a multiplier effect. Invest in one generation's education, particularly girls', and you're investing in the next generation too.

The IB Economics diagram: investing in education and healthcare shifts the PPC outward (from PPC1 to PPC2) and shifts LRAS to the right - reflecting a genuine increase in productive capacity, not just demand. Source visit: IB Economics Diagrams

IB Economics Real-life example: Rwanda is one of the most cited development success stories of the 21st century. Following the 1994 catastrophic genocide, Rwanda rebuilt its human capital almost from scratch through aggressive investment in primary and secondary education, community health workers, and healthcare infrastructure. Between 2000 and 2020, Rwanda's child mortality rate fell by over 70%. Life expectancy rose from around 48 to over 69. GDP per capita grew roughly fivefold. The investment in people drove everything else forward.

Barrier 4: Dependence on Primary Sector Production

What's wrong with being really good at farming, mining, or fishing?

Nothing wrong really. But when your entire economy depends on primary sector production - extracting and cultivating raw materials - then you have a serious vulnerability problem.

The primary sector covers agriculture, livestock farming, mining, commercial fishing, and forestry. Countries that over-rely on it tend to show the lowest human development indicators. Why?

Three main reasons. First, the output or production obtained from the primary sector depends on climate and weather - a drought, a flood, a hurricane, and suddenly your entire GDP takes a hit. Second, the primary sector relies heavily on non-renewable resources: oil, gas, minerals. Once they're gone, they're gone. Third, commodity prices are volatile - your export earnings can swing without control from one day to another, as the price of commodities is based on global demand and you have no control over it.

There's also the famous "resource curse" - the paradox that countries with abundant natural resources often develop more slowly than those without. Nigeria, for all its oil wealth, has over 100 million people living in extreme poverty. The Democratic Republic of Congo contains some of the richest mineral deposits on earth - including the cobalt your phone battery depends on - and consistently ranks near the bottom of the Human Development Index.

IB Economics Real-life example: Qatar and the UAE. Both started with massive oil wealth and could easily have become dependent on it. Instead, they invested proactively in diversification - infrastructure, education, financial services, tourism, technology. Dubai is now a global hub for trade and finance. The oil is still there, but it's no longer their only activity. That's the lesson: use your primary sector earnings to build the conditions for a more complex, diversified and resilient economy.

Barrier 5: Lack of Access to International Markets

Imagine a small farmer in Mali who grows genuinely excellent cotton - high quality, competitive price. She wants to sell it internationally. But the moment she tries to access European or American markets, she hits a wall of tariffs, quotas, embargoes, and administrative barriers that make it nearly impossible to compete.

Meanwhile, American cotton farmers receive billions in government subsidies, allowing them to sell at artificially low prices that undercut producers in ELDCs.

International market access is the ability to sell goods and services globally and enter foreign markets. Countries with strong export earnings consistently show higher levels of economic development. But for many ELDCs, the problem is reaching that level.

Trade liberalisation has opened doors for some - the rise of export-led growth in South-East Asia is proof of that. But the least developed countries often remain locked out, unable to compete with subsidised goods from MEDCs, blocked by protectionist measures that wealthy nations justify domestically whilst preaching free trade abroad. It's one of global economics' more glaring hypocrisies.

IB Economics Real-life example: The WTO's Aid for Trade initiative and the EU's Everything But Arms scheme (which grants tariff-free access to the EU for least developed countries on all goods except weapons) are attempts to address this. Progress has been made. But as long as agricultural subsidies in the US and EU remain, the structural disadvantage for ELDCs in primary commodity markets goes on and on.

Barrier 6: The Informal Economy

This one surprises my students every year.

The informal economy - sometimes called the parallel economy or shadow economy - refers to all economic activity that goes unrecorded in a country's GDP. Street vendors. Subsistence farmers. Informal construction work. Bartering. Cash-in-hand services.

Most of it isn't illegal. It's just unofficial.

61% of the global workforce - approximately 2 billion people - participate in the informal economy, according to the 2018 ILO report.

In some ELDCs, the informal sector represents up to 90% of total employment. Yes, that's almost the whole economy.

So why is it a barrier to development? There are several reasons. First, informal workers and businesses pay no taxes, which starves governments of the revenue needed to fund schools, hospitals, roads, and public goods. Second, informal economic activity is nearly impossible to monitor or regulate, making policy implementation almost impossible. Third - and this is the IB Economics' ethical dimension - informal economies frequently involve child labour and worker exploitation, with little legal protection for the most vulnerable.

The International Labour Organisation (ILO) is very clear about this: without formalisation, "achieving decent work for everyone and social equity will remain a distant dream."

IB Economics Real-life example: India's informal economy accounts for roughly 50% of GDP and 80-90% of total employment. The government's has attempted to formalise the economy through digital payments (via the UPI system - now the world's largest real-time payments platform), GST implementation, and financial inclusion schemes and this has been a genuine attempt to bring informal workers into the taxable, regulated economy. However, results are mixed but the direction is clear: formalisation is essential for development.

Barrier 7: Capital Flight

Capital flight:

Capital flight refers to the large-scale withdrawal of assets and capital from a country, typically caused by economic or political uncertainty.

Imagine you're a wealthy business owner in Venezuela in 2016. Inflation is running at several hundreds percent. The government is nationalising private companies. Political instability is the norm and not the exception. What do you do?

You move your money out. As quickly as you can. Overseas bank accounts, foreign property, dollar assets - whatever it takes to protect your wealth from losing its value.

That's capital flight - the large-scale withdrawal of assets and financial capital from a country, usually driven by economic or political uncertainty. The effects of capital flight on economic development are devastating.

Capital flight signals a collapse of investor confidence. When wealthy individuals and businesses move money out, it reduces the domestic capital available for investment. FDI dries up. Multinational corporations look elsewhere. Unemployment rises. National income falls. The country becomes poorer exactly at a time when it cannot afford to.

Countries experiencing political turmoil, civil war, social unrest, or international conflict are most vulnerable. Sudan, Myanmar, Zimbabwe, and Haiti are all recent examples of economies losing out on capital because the conditions for confident investment were non-existent.

IB Economics Real-life example: Following Russia's invasion of Ukraine in 2022, Russia experienced one of the most dramatic capital flight episodes in modern history. Estimates suggest hundreds of billions of dollars left Russia in 2022 alone, as wealthy Russians moved assets abroad in anticipation of sanctions and economic instability. The long-term damage to Russia's economic development prospects is still to be quantified.

Barrier 8: Indebtedness

Indebtedness:

Indebtedness occurs when a country consistently borrows beyond its means, with accumulating interest creating a cycle of escalating debt that threatens growth and development.

It basically means owing money. And for many ELDCs, public debt is not only a political problem but it is also one of the main reasons why economic development cannot be financed properly.

A country borrows to fund development - infrastructure, schools, hospitals. Reasonable enough. But if growth doesn't materialise fast enough, or if interest rates rise, or if commodity prices fall, suddenly the debt repayments become unmanageable. So the country borrows more to service the existing debt. Interest builds. The debt grows faster than the economy. And the government spends an increasing share of its revenue on debt repayment rather than on economic development.

Zambia became the first African country to default on its debt during the COVID-19 pandemic in 2020, after years of borrowing - partly from Chinese lenders - for infrastructure projects that didn't generate sufficient returns. By 2023, Zambia was spending more on debt servicing than on health and education combined.

This is not unique to Zambia. The IMF estimates that over 60% of low-income countries are currently at high risk of debt distress or already in it. The post-COVID surge in borrowing, combined with rising global interest rates, has pushed the debt crisis to its most problematic point in decades.

IB Economics note: lower interest rates and rising national income can reduce debt burdens - but for countries already in the debt spiral, external intervention (debt relief, restructuring, new concessional lending) is often necessary in order to allow these countries to carry on.

Barrier 9: Geography - Including Landlocked Countries

Geography affects development through multiple channels. Access to coastlines and navigable rivers dramatically reduces transport costs - historically, sea trade has been the backbone of international commerce. Cities like London, Shanghai, Amsterdam, Hong Kong, and Singapore didn't become global economic powerhouses by accident. They're all on the water.

Landlocked countries:

Landlocked countries face higher export costs and greater dependency on neighbouring nations' infrastructure, creating a structural disadvantage for development.

To export anything, they have to transport it overland through neighbouring countries - adding costs, time, and dependency on those neighbours' infrastructure and political goodwill. There are 44 landlocked countries in the world. The vast majority are in the bottom half of the Human Development Index.

Bolivia, for example, lost its Pacific coastline to Chile in the War of the Pacific (1879–1884) and has never fully recovered economically. It remains one of South America's poorest countries, partly because every single export has to travel overland before it reaches a port.

Geography also shapes agricultural capacity. Fertile soils, reliable rainfall, and temperate climates support productive farming. Arid regions face soil erosion, water scarcity, and vulnerability to desertification. The Sahel region of West Africa - stretching across Mali, Niger, Chad, and Burkina Faso - is a well-known example: chronically exposed to drought, food insecurity, and land degradation that makes sustained agricultural development incredibly difficult.

Barrier 10: Tropical Climates and Endemic Disease

Tropical countries often have breath-taking natural beauty, extraordinary biodiversity, and rich cultures. They also bear the burden of endemic diseases - illnesses that are permanently and consistently present in a population.

The warm, humid conditions of tropical regions are ideal for bacterial and parasitic infections. Malaria - transmitted by mosquitoes - kills around 655,000 people per year, the vast majority in Sub-Saharan Africa. UNICEF identifies it as the third leading cause of child mortality worldwide. However, Malaria it's both preventable and treatable. Deaths aren't inevitable - they're a consequence of insufficient healthcare infrastructure, poverty, and lack of access to basic interventions like mosquito nets and antimalarial drugs.

Beyond malaria, diseases including diphtheria, measles, polio, and hepatitis A all flourish in tropical settings. These diseases have been controlled in wealthier, cooler-climate nations a long time ago.

The economic impact goes beyond the tragic human cost. Endemic disease reduces labour productivity - sick workers produce less. It alters population age structures - high child mortality leads to higher birth rates, as families have more children in the expectation that some won't survive. More children per family means fewer resources per child, reducing educational investment and perpetuating poverty. High fertility rates also reduce female workforce participation, as women focus on caregiving - putting further strain on human capital development.

IB Economics Real-life example: The Gates Foundation's investment in malaria elimination - over $6 billion since 2000 - and the rollout of the RTS,S malaria vaccine (approved by the WHO in 2021 and now being scaled across Sub-Saharan Africa) represent perhaps the most promising development in decades. Early data suggests the vaccine could prevent tens of thousands of child deaths annually. This is what targeted intervention against a development barrier looks like in practice.

IB Economics Summary

Ten barriers. Ten snakes on the board. And what is more relevant - they don't operate independently. They interact.

A landlocked country with a tropical climate, endemic disease, and a heavy dependence on primary sector production will almost certainly have low human capital, poor infrastructure, limited international market access, and a large informal economy. Each barrier reinforces the others. That's why economic development is genuinely hard - and why simplistic solutions ("just grow your GDP" or "just get more foreign aid") rarely work on their own.

What your IB Economics teacher wants you to understand - and what the real world demonstrates time and time again - is that tackling these barriers requires simultaneous, coordinated action across economics, governance, health, education, and international policy. Rwanda's transformation. China's poverty reduction. The UAE's diversification. None of these happened by chance or by applying a single policy. They happened because multiple barriers were addressed at once with the right policy package.

Recap

Frequently Asked Questions: Barriers to Economic Growth and Development In IB Economics

Q1: What are the main barriers to economic development in IB Economics? The IB identifies ten core barriers: rising economic inequality, lack of infrastructure and technology, low human capital, primary sector dependence, lack of international market access, the informal economy, capital flight, indebtedness, geographical disadvantages (including being landlocked), and tropical climates with endemic diseases.

Q2: Why is the informal economy a barrier to development? The informal economy goes unrecorded in GDP, meaning workers and businesses pay no taxes - depriving governments of revenue for public services. It's also difficult to regulate, often involves worker exploitation and child labour, and prevents the formalisation of property rights and credit access that formal economic participation enables.

Q3: How does geography affect economic development? Landlocked countries face higher transport costs and dependency on neighbouring nations' infrastructure, limiting export competitiveness. Tropical climates increase exposure to endemic diseases and agricultural vulnerability. Coastal access has historically been one of the strongest predictors of trade integration and economic success.

Q4: What is capital flight and why does it harm developing countries? Capital flight is the large-scale outflow of assets and financial capital from a country due to economic or political instability. It signals collapsed investor confidence, reduces domestic investment, deters FDI, raises unemployment, and lowers national income - creating a self-reinforcing cycle of decline.

Q5: Why isn't GDP growth alone enough to achieve economic development? GDP growth only measures the size of an economy, not how income is distributed. If growth benefits a wealthy minority while the majority lack access to education, healthcare, and capital, development does not occur. Economic inequality means growth can coexist with persistent extreme poverty - as seen in countries like Nigeria and Brazil.
