拨开谜团

    约翰内斯堡--恐怖主义和全球气候变暖在许多人的心目中是对地球最大的威胁。在美国,布什政府想要为边境安全和移民执法增加经费将近20%。现在,花费在帮助纽约、新泽西以及康涅狄格州的公交系统防止和应对恐怖主义袭击的经费达到一亿五千万美元以上。

    但是国际恐怖主义每年杀害总共四百人。我们愿意花多少钱来降低这一死亡数目25%呢?十亿美元还是一千亿美元?

    与此同时,决策者们云集夏威夷讨论一项气候变化条约来取代京都议定书。各个环境院外活动团体想要让下一个条约比京都议定书更进一步,而这一议定书已经每年让全世界花费一千八百亿美元。实际上,通过京都议定书或者相似的条约来减缓全球气候变暖的努力所带来的效果微不足道,只不过在2100年前把温度上升延迟七天而已。

  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.
