"Ostrowski’s command of the topic is impressive. His study includes many interesting facts that will be valuable for researchers. He conducted in-depth interviews with high-ranking representatives of numerous bodies...Ostrowski’s study provides a good example of how informal political relations and behaviour are an important mechanism in maintaining the Kazakh regime. It is a good empirical contribution to the existing literature on resource-rich post-Soviet countries and their political economy." - Julia Kusznir, Europe-Asia Studies, 62:8, 2010"[The study] markedly improves our understanding of the political economy of a petrol-rich state... [it] will become a touchstone for anyone working in this area... [and] represents an important contribution to our understanding of Kazakhstan in the 1990s and 2000s." - Edward Schatz, University of Toronto; Central Asian Survey, Vol. 30, No. 1, March 2011
