The privatization carried out under the Thatcher and Major governments in Britain has been widely (although not universally) considered a success, and has greatly influenced the privatization of state industries in the transition economies of Eastern Europe.

In successive chapters, he examines firms and productivity changes; shareholders' windfall gains and evidence of underpricing and outperformance in privatized companies; workers, management, and changes in industrial relations; consumers and the quantity and quality of goods after the change to public ownership; and taxpayers and the interplay between privatization and tax reform.
