Evolution of Key Features of Public Policies
(1-4 scale)



Note: For Colombia, Mexico and Paraguay, policy indices were calculated for two sets of data, corresponding to different periods in time. The periods are as follows: Colombia I = before 1991, Colombia II = 1991-present; Mexico I = 1950-mid 1990s, Mexico II = 1990s-2003; and Paraguay I = 1954-1989, Paraguay II = 1989-2003.
