- Abstract:
- Many African countries have placed economic diversification high on the policy agenda, yet they first need to define what it means in their specific structural and socioeconomic contexts. For decades, economic diversification has been a policy priority for low- and middle-income economies. In the words of former managing director of the International Monetary Fund (IMF), Christine Lagarde, “We know that economic diversification is good for growth. Diversification is also tremendously important for resilience.” Unfortunately, this goal continues to elude many African countries. In fact, the continent is home to eight of the world’s fifteen least economically diversified countries. This reality weakens the foundation of their economic transfomation and slows their pace of progress. It also makes these countries particularly vulnerable to sudden external shocks, as the pandemic-induced disruption of tourism and oil-dependent economies has illustrated. Given the importance of diversifying African economies, it is critical to recognize how various dimensions of diversification can have different implications for the menu of policy options. Closely associated with the process of structural transformation from lower to higher productivity sectors, economic diversification has three evident dimensions. The first relates to the expansion of economic sectors that contribute to employment and production or gross domestic product (GDP) diversification, and the second is associated with international trade or exports diversification. This paper, however, focuses on a third dimension that the economics literature pays scant attention to: fiscal diversification. This fiscal element involves expanding government revenue sources and public expenditure targets and can therefore play a central role in helping to catalyze broader economic transformation through the expansion of activity in specific industries and sectors. It is also critical that policymakers effectively measure the extent to which this objective is being achieved. Both the expansion of existing economic sectors and the creation of new ones may diversify an economy. But these processes are vastly different in practice and will garner distinct outcomes. Of the main tools used by economists to measure diversification, the Theil Index differentiates between the respective contributions of new economic sectors and existing ones to overall diversification. Another tool widely used by development practitioners—the Public Expenditure and Financial Accountability (PEFA) framework—has significant potential for evaluating fiscal diversification but would need to capture more information on government revenue collection and spending and link them to policy objectives.
