Low-income countries face vast development needs. One of the biggest impediments to rapid growth is a massive “infrastructure deficit.”
In sub-Saharan Africa, for example, indicators of road and rail infrastructure are only about half those in developing countries as a whole—comparisons with advanced economies, of course, would look even bleaker. Insufficient power generation capacity and telecommunications networks are also a big constraint. It is clear that large-scale investment programs, sustained over many years, will be needed to close these gaps. Both private and public sectors will have a role to play.
The snag, of course, is that investment spending typically has to be financed by borrowing, and until quite recently, the ability of low-income country governments to take on more debt has been severely hampered by legacies from the past. Many had built up unsustainable debt as a result of bad borrowing and spending decisions, poor project implementation, weak revenue systems (governments could not collect the taxes needed to service the debts), and often bad luck (as their economies were hit by global shocks). In effect, these countries were caught in a debt trap.
