Education: A Key Force Behind Inclusive Economic Growth

Education has long been recognized as one of the most important contributors to economic development. However, understanding exactly who benefits from education policies and why remains an ongoing area of research.

Recent findings reveal that education does more than simply support economic growth. It also plays a critical role in ensuring that growth benefits a wider portion of society.

When education systems are designed effectively, they can become powerful tools for reducing income inequality and narrowing gender gaps.

How Education Helps Reduce Poverty and Gender Inequality

Many economic studies focus primarily on how education influences individual earnings. While these studies demonstrate that education can increase income, there has been less research into which groups benefit the most from educational policies.

Recent research examines how education has contributed not only to economic growth but also to reducing extreme poverty and gender inequality worldwide over the past several decades.

The findings from this analysis are quite clear.

One way to understand this impact is through the well-known “elephant curve”, which illustrates real income growth across the global population since 1980—from the poorest individuals to the wealthiest.

The curve shows that income growth has been strongest among middle-income groups, particularly in countries such as China and India, as well as among the highest-income earners in developed economies.

In this analysis, a portion of the growth can be attributed directly to expanding access to education, while the remaining growth results from other factors such as technological innovation and increased capital investment.

Why Education Supports Inclusive Growth

Education has proven particularly beneficial for people living in poverty. This is not simply because developing countries have expanded schooling opportunities, but because education policies often deliver the greatest gains to lower-income groups within each country.

A clear example comes from Indonesia’s INPRES school construction program in the 1970s, a large-scale initiative aimed at expanding educational access.

Research shows that the policy had a disproportionately positive impact on poorer populations. For every additional year of schooling enabled by the program, low-income individuals experienced income increases of around 20%, while wealthier individuals saw income gains closer to 10%.

This demonstrates that well-designed education policies can significantly improve opportunities for disadvantaged groups.

But what exactly makes education such an effective tool for inclusive development?

There are three important factors to consider when designing education policy.

1. Education Influences the Entire Economy

Education does more than raise the income of individuals who receive it. It also affects the broader economy.

Many people assume that education only benefits those who attend school or gain qualifications. In reality, expanding education can create indirect economic benefits for many workers.

When more individuals gain advanced skills, the supply of skilled labor increases. This can lower the wage premium for highly skilled workers while increasing demand—and potentially wages—for workers with fewer formal qualifications.

As a result, even individuals who did not receive additional education can benefit indirectly from the expansion of educational opportunities.

Research suggests these broader economic effects may account for as much as 40% of the income gains observed among people living in poverty.

This means policymakers should view education not only as a personal investment but as a policy with wide-ranging economic consequences.

2. Education Must Adapt to Technological Change

Another important insight is that education policy must evolve alongside technological progress.

In recent decades, many economies have experienced skill-biased technological change. This means new technologies increasingly require workers with specialized knowledge and higher-level skills.

For countries to fully benefit from technological advancements, they must ensure their education systems produce enough skilled workers to meet labor market demand.

If not, the benefits of technological progress may be captured primarily by a small group of highly educated individuals.

While expanding access to basic education remains crucial, increasing access to higher education is also essential. This helps ensure that technological change benefits society broadly rather than increasing inequality.

3. The Returns to Education Are Uneven

The benefits people receive from education are not the same everywhere.

The returns to schooling vary significantly across countries and across different levels of education.

Research often shows that returns are convex, meaning they tend to increase as people pursue higher levels of education. In many low-income countries, the financial benefits of tertiary education are significantly greater than those of primary or secondary education.

This creates a challenge for inclusivity because university access is often limited to students from more privileged socioeconomic backgrounds.

To make education systems more inclusive, two key solutions can be considered.

First, governments should invest more resources into improving the quality of basic education, particularly in developing countries where educational outcomes often remain weak.

Second, countries should work to expand access to higher education, ensuring that students from a wider range of backgrounds can benefit from advanced learning opportunities.

Doing so would allow the economic gains from education to be shared more broadly while also helping reduce inequality in labor markets.

The Bigger Picture

Education remains one of the most powerful tools available for promoting both economic growth and social equality.

When designed effectively, education policies can raise incomes, reduce poverty, and create opportunities for people across all levels of society.

By expanding access to quality education at every level—and aligning education systems with technological progress—countries can ensure that the benefits of development are shared more widely and more fairly.
