身陷囹圄的美国经济

伯克利—美国拥有5%的世界人口和25%的狱中人口——大约220万人,五倍于1980年。美国成年人中每100人就有一人深陷囹圄——这一人均比例为世界之最,比西欧或其他民主国家高5—10倍。社会和经济成本也同样高昂。

近几十年来美国监狱人口的激增是惩罚性预防犯罪措施大行其道的结果,包括更加严格的毒品惩罚和强制性最低刑期,其背后有数量日益增加的警察和执法队伍作为支持。除了警察队伍扩张所带来的财务成本和司法体系压力增加之外,每年有600亿美元花在了州和联邦监狱经费上,而20年前这一数字是120亿。除此之外,囚犯(其中许多因为非暴力犯罪而入狱)及其家庭和社区也承受了巨大的成本——其中穷人、受教育程度低下者、非洲裔和拉丁裔美国人以及精神病人负担尤重。

也许最糟糕的部分是人们所期待的美国“严刑峻法”方针所应有的效果并没有实现。事实上,高入狱率和低犯罪率之间相关性很弱。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
