So, if the structural factors have always been there and if their influences would have, if anything, diminished over time, those factors cannot explain why Africa used to grow at a decent rate in the 1960s and 70s and then suddenly failed to grow. The sudden collapse in growth must be explained by something that happened around 1980. The prime suspect is the dramatic change in policy direction around the time.
Since the late 1970s (starting with Senegal in 1979), Sub-Saharan African countries were forced to adopt free-market, free-trade policies through the conditions imposed by the so-called Structural Adjustment Programs (SAPs) of the World Bank and the IMF (and the rich countries that ultimately control them). Contrary to conventional wisdom, these policies are
The result of the SAPs – and their various later incarnations, including today’s PRSPs (Poverty Reduction Strategy Papers) – was a stagnant economy that has failed to grow (in per capita terms) for three decades. During the 1980s and 90s, per capita income in Sub-Saharan Africa
So, the so-called structural factors are really scapegoats wheeled out by free-market economists. Seeing their favoured policies failing to produce good outcomes, they had to find other explanations for Africa’s stagnation (or retrogression, if you don’t count the last few years of growth spike due to commodity boom, which has come to an end). It was unthinkable for them that such ‘correct’ policies could fail. It is no coincidence that structural factors came to be cited as the main explanations of poor African economic performance
Pointing out that the above-mentioned structural variables were invoked in an attempt to save free-market economics from embarrassment does not mean that they are irrelevant. Many of the theories offered as to how a particular structural variable affects economic outcome do make sense. Poor climate can hamper development. Being surrounded by poor and conflict-ridden countries limits export opportunities and makes cross-border spill-over of conflicts more likely. Ethnic diversity or resource bonanzas can generate perverse political dynamics. However, these outcomes are not inevitable.
To begin with, there are many different ways in which those structural factors can play out. For example, abundant natural resources can create perverse outcomes, but can also promote development. If that weren’t the case, we wouldn’t consider the poor performances of resource-rich countries to be perverse in the first place. Natural resources allow poor countries to earn the foreign exchanges with which they can buy advanced technologies. Saying that those resources are a curse is like saying that all children born into a rich family will fail in life because they will get spoilt by their inherited wealth. Some do so exactly for this reason, but there are many others who take advantage of their inheritance and become even more successful than their parents. The fact that a factor is structural (that is, it is given by nature or history) does not mean that the outcome of its influence is predetermined.
