Macroeconomic Determinants of Domestic Private Investment in Africa: An Empirical Analysis

Abstract

During the late 1970s and early 1980s, many African countries experienced a profound slowdown in economic growth. The growth rate of real per capita GDP fell from 0.4% per year during the 1973-80 period to 1.2% per year during the 1980-89 period.' The causes-internal and external-of Africa's economic decline and the strategies for restoring economic growth are much debated. Nevertheless, broad consensus has emerged on the importance of (i) increasing total investment and (ii) promoting private-sector development and increasing its share of total investment for long-term growth.2 It is widely recognized that gross domestic investment fell substantially in Africa during the 1980s and remains severely depressed across the region. The proportion of total domestic investment in GDP fell from 20.8% per year during 1973-80 to 16.1% per year during 1980-89. In some countries, investment has fallen to less than 10% of GDP-a level that is insufficient even to replace depreciated capital. In Africa, the minimum investment needed to replace depreciated capital is estimated at 13% of GDP.3 In recent years, there has also been a growing recognition among many African leaders, faced with new realism and pragmatism, that the private sector could play a significant role in economic development. The focus in the longer term of structural adjustment programs and sectoral reforms adopted by these countries is on creating more appropriate incentives and a framework for private-sector development as the basis for achieving sustainable economic growth. In addition, multilateral and bilateral institutions have developed new initiatives with priorities for private-sector development. In 1989, the International Finance Corporation, an affiliate of the World Bank, es-
