Inequality and Africa’s IDA Middle Income Trap

Ravi Kanbur's picture



Inequality is of concern for at least three reasons. First, lower inequality per se is an objective for a decent society. Second, lower inequality improves the efficiency of economic growth in achieving poverty reduction. Third, high inequality impedes growth itself, through its impact on social cohesion and the investment climate.

A simple framework for thinking about trends in inequality is to think of income as the result of three ingredients. The first ingredient is the assets (the things a person has to produce income), like a tractor or a sewing machine or an education. The second ingredient is the return a person gets on those assets (how much do those things produce). For example, how much does the tractor increase yields? What is the return on a person’s high school education? If we multiply each thing a person has (the assets) by what that thing can produce (the return), and then add up across all the thing-return combinations, we get a person’s total market income. Then we add in the third ingredient, income from taxes and transfers. Educated workers tend to get higher returns for their skills: That’s called the skill premium. Within this framework, inequality of market income is composed of two elements—the inequality of assets and the inequality of rates of return to assets. Inequality of take-home income of course also depends on tax and transfers.

Global forces are leading to greater inequality in rates of return to assets. Returns on land and on physical and financial capital are rising faster than returns on labor, and returns on skilled labor are rising faster than returns on unskilled labor. The forces of technical change are set to increase inequality of market incomes in a business-as-usual scenario. Openness in trade and investment will transmit these trends to all parts of the world.

These forces will impact Africa no less than other trends in trade or finance or investment. But Africa will be particularly vulnerable to rising inequality for three reasons. First, because of Africa’s natural resource base, the inequality consequences of rising returns to land and resources can be significant. Second, African urbanization is still low, and urbanization is often associated with rising inequality. Third the ethno-linguistic diversity of Africa’s population means that inequality takes on a socio-political salience that goes beyond the standard economic dimensions.

It is neither feasible nor desirable to stand against the tide of technical progress and global integration which underlies the forces for both growth and rising inequality. Rather, if inequality is a concern then policy makers must intervene proactively to achieve a more equal distribution of assets. In particular, they must address the inequality of human capital in its many dimensions, starting with education and health. The positive experience of many Latin American countries in achieving falling inequality – a reversal of fortune relative to global trends and relative to their own history – stands as an example of what can be done with purposive policy intervention that targets redistribution with the objective of building up the human capital of the poorest.

Where will the resources come from to implement policies and interventions to reduce the inequality of physical and human assets? Internal resources will have to include taxation of resource rents, which is economically efficient on classical public finance grounds, and is progressive given that those rents tend to accrue to the wealthy. External resources targeted towards addressing the inequality of assets can be made available in the form of development assistance. However, Africa faces a looming problem on that front.

As African countries cross into middle income country status, they will find themselves in the trap of losing concessional resources for development. The International Development Association (IDA), the World Bank’s fund for the poorest, is the leading example of the problem. Over the next five to seven years many countries in Africa will cross the specific per capita income threshold of graduation from IDA. Upon graduation, if the current rules are followed then not only will inflow of resources dry up, but the maturity of the remaining stock of IDA debt will halve—quite the double whammy.
 

Despite having crossed the graduation threshold, last year India argued for and got continued access to IDA for three years, under IDA 17. Now is the time for African countries to come together and argue for a major rethink on IDA graduation rules which will allow them continued access to concessional resources with which to face the significant development issues which will still remain, not least the need to address the global forces leading to rising inequality.

I believe that Africa is a wealthy continent in which offers many opportunities for profitable investment in different sectors.The challenges we facing in the economy is transparency and accountability. The world needs a long-term strategic plan for a global partnership between rich and poor. Such a plan should use the strength of free markets and rules based on global ethics.My question is should we focus more on government intervention in this economical problem?
