Commodity Prices and Growth in Africa
研究了非洲国家独立后从快速增长转向威权统治，再到1970年代中期至1990年代中期增长放缓的过程，指出治理失败是增长缓慢的原因，并暗示近期民主化可能促进增长。
African states that came to independence by the late 1960s made a rapid transition to authoritarian rule during a period of reasonably robust growth. Growth then faltered badly from the mid-1970s to the mid-1990s as these regimes coped with external shocks and varying degrees of fiscal crisis. Leading critics embed Africa's slow growth in failures of governance associated with “weak” authoritarian rule. These provide important insights into policy patterns while suggesting the growth-promoting potential of Africa's recent Democratization.
