The first comprehensive statistical analysis of human rights attainments and improvements over time, this book seeks to answer the question, Why do some countries better observe human rights than others, and what can be done to advance the cause of human rights around the world? Haas’s data support his argument that economic sanctions against countries that violate human rights are likely to be counterproductive. When information flows more freely and economies are more pluralistic, competing political parties emerge, and basic human rights are increasingly respected. When liberal democracies have sufficient prosperity to adopt welfare state policies, women’s rights are most likely to advance.
