Although it is difficult to measure corporate fraud, Levi concludes that the incidence of such fraud is increasing. His discussion regarding the impact of commercial crime is persuasive and he correctly notes that some manifestations of white collar crime are dealt with by regulatory agencies rather than by criminal courts. The critique points out that class action has become a public enforcement tool in civil law and that the development of self-regulatory agencies suggests the development of multifaceted control systems. Levi's survey of attitudes toward commercial crime is based on his own empirical research. He notes that fraud is not a homogeneous category, a point obviously relevant to sentencing. Levi further notes the influence of different commercial fraud. He points to leniency and disparities in sentencing, but the critique suggests that sentencing issues should be researched further. Levi's discussion of criminal process reforms deals with the fragmented prosecution system, international cooperation, money laundering, and narcotics offenses.
