One of the most hotly debated topics in development economics is: what does it take to steer a poor country from Third World to First World status?

It is a debate of particular relevance in Africa, which is home to a large number of countries in the Third World category.

It also has some of the fastest-growing economies in the world.

Third World countries are characterized by a big agrarian sector and a huge proportion of the population living in rural areas. They are also marked by low productivity, disease, high infant mortality, lack of potable water and poor infrastructure.

First World countries are highly urbanized, and citizens enjoy universal access to health, education and housing. They also exhibit high productivity, strong service sectors and freedom of movement because of infrastructure.

Within decades, many Asian countries made the transition from Third World status to First World status.

Some countries in Africa are well placed to make this transition. These include Ethiopia, Rwanda, Uganda and Kenya, Ghana, Côte d’Ivoire, Gabon, Mozambique, Angola and South Africa.

We believe that these countries can emulate the “Asian miracle,” but only if governments take decisive steps to achieve certain outcomes. East Asia has a remarkable record of high and sustained economic growth. From 1965 to 1990 the 23 economies of East Asia grew faster than those of all other regions of the world. Most of this achievement is attributable to seemingly miraculous growth in the eight economies studied.

First, gross domestic product (GDP) per capita or the average household income must be improved. It is impossible to sustain important aspects of human development without this.

Second, state intervention and robust national leadership are crucial. The economic strategies of successful countries were influenced by leaders who were committed to rapid development. They had a focus on growing human capital. This in turn led to increased productivity, increased household incomes and an improvement in the general standard of living.

Examining the economic trajectory of some countries between 1960 and 2016 suggests that it can take about 25 years to turn a nation from Third World to First World.

Japan was the outright leader, but in time other Asian nations started leading in certain industries. Examples include Taiwan and South Korea. They had no mineral wealth. What they had, instead, were national systems of innovation and, critically, they invested in human capital. They copied technologies from First World economies until they were on par and even overtook the First World countries. In many cases they started off equal or lower in GDP per capita when compared with a number of African countries.

For example, in 1957 Ghana and South Korea had about the same per capita GDP.

Taiwan’s economy underperformed under Japanese colonial rule between 1895 and 1945. In the 1950s the country was an agrarian economy with the same living standard as Congo. But by 2010 it had overtaken its former colonial master to become the No. 1 producer of semi-conductors in the world.

The point is that a colonial past is no excuse for Africa’s failure so far to catch up, emulate and leapfrog.

Success stories of the kind envisioned here have been controversially called miracles. Yet there is no magic.

Studies have shown that nations that made serious economic progress focused on growing the average income of their citizens. For example, Japan focused on this between 1950 and 1972 and doubled its GDP per capita.

Nineteen out of 23 of the poorest nations in the world are in Africa.

Yet no African leader has pursued with single-minded determination the improvement of household incomes. Instead their focus has generally been on economic growth with trickle down being viewed as a panacea for higher GDP per capita.

Even in South Africa there is no set period for the poor in the black majority (90 percent of the population) to move into the middle class proper, with access to tertiary education, white goods and shelter, and annual household expenditure close to US$36,500.

Household incomes improve when the largest number of people get involved in technology-based productivity work. Even agriculture needs to be high-tech and include agro-processing. This is a path currently being followed by Ethiopia.

The Asian Tigers have been criticized for lack of democracy, favoritism in allocating resources, cronyism and protectionism. But there is unanimity that they have succeeded in taking the masses of their populations out of poverty, unemployment and inequality.

Another key area of focus among the Asian Tigers has been investment in their youth. Africa should exploit the youth dividend, its most important natural resource.

The Asian Tigers also all have a national innovation system that links government, well-funded research and development institutions such as the universities and industry. Taiwan boasts 21 research institutes, some covering the most advanced technologies like nano-technologies. African nations do not have such institutions.

There are signs that some of these lessons have been taken to heart. Rwanda, for example, is doing very well by investing in information, technology and communication, and in its own people.

Ethiopia has invested in agrarian reform to subsidize industries through economic processing zones.

These efforts arguably will bear fruit in the transition to First World status.

Very few nations prosper without well-organised and strategically focused hard work and sacrifice. Africans need to learn to direct effort and resources with a long-term goal. Leadership is key.
