Most recent literature on military government is extremely skeptical of the possibility of effective military reformism. This scepticism, encouraged by various behavioural hypotheses, has been further strengthened by a number of cross-sectional analyses, which seem to show that most military governments are unstable, conservative, and indifferent at economic management.1 The military government in Peru, therefore, appears to be something of an exception. Its first President, General Velasco, stayed in office for nearly seven years, and his successor, General Morales Bermúdez, has promised that the nature of the regime will not be drastically changed. Even more important, the Government claims to have carried out a comprehensive set of agrarian, industrial and social reforms that were aimed at bringing Peru out of its former underdevelopment. Moreover, the Government has claimed to have achieved all this during a seven-year period in which the conventional criteria of economic success – a substantial growth in real income per capita, a moderate rate of inflation and a reasonably stable exchange rate – also appear to have been met.
