Minxin Pei in Think again: Asia’s Rise:
Even when you look at autocracies credited with economic success, you find two interesting facts. First, their economic performance improved when they became less brutal and allowed greater personal and economic freedoms. Second, the keys to their successes were sensible economic policies, such as conservative macroeconomic management, infrastructural investment, promotion of savings, and pushing exports. Dictatorship really has no magic formula for economic development.
