Basically, this book is a very strong and appealing summary of the consequences of over-reliance on oil production for developing countries. Not only results, but also underlying causes are considered: most attention is given to institutional and political aspects of what Karl calls "petrolization" of the state. He argues that petroleum is the only product, which creates strong long-lasting ties among politicians and institutions involving them into constant seeking of oil revenues (for their own as well as for state benefit). Future decisions in this environment are determined by actions taken in the past, which makes it very hard to break away from this circle. The case of Venezuela is especially well considered; much of the information is taken from Karl's conversations with Venezuelans top governmental officials and, hence, is of a great value. Carefully chosen data are well presented on a passionate manner which conveys the dramatic nature of changes brought by petroleum in this country.
The future of new oil-producers becomes less shinning as we look at the data provided by the author. Only Norway, who managed to overcome most of the negative aftermaths of its oil windfalls, deemed as a winner within the group of oil producers. Karl ascribes this success to a well-prepared and robust bureaucracy and stable democracy existing in Norway.
The only problem I see in this book is its superficial treatment of economic factors related to "petrolization" of the state. In this context, Oil Windfalls: Blessing or Curse? by Alan Gelb and Associates (1988) or Sustainable Development In Mineral Economies by R. Auty and Mikesell (1998) or would be the best supplement.
