In this book, Federico Sturzenegger and Mariano Tommasi propose formal models to answer some of the questions raised by the recent reform experience of many Latin American and eastern European countries. The book is organized around three basic questions: first, why do reforms take place? Second, how are reforms implemented? And third, which candidates are most likely to undertake reform? Although most of the chapters deal with policy issues in developing economies, the findings also apply to areas such as social security and health care reform in industrialized countries.
