Policymakers have responded to successive economic downturns in essentially the same Keynesian way since the 1950s. Fiscal deficits have been allowed to rise and interest rates to fall to stimulate aggregate demand. Though Keynes hardly anticipated such repeated use of macro instruments, these policies have worked. As a result, the policy response to the current crisis has been “more of the same”. Many policymakers remain confident that this will eventually generate a sustained recovery. Yet it is worth reflecting on why it might not work this time, and what other public policies might help foster recovery. In short, what is Plan B?
自上世纪50年代以来，政策制定者应对接连不断的manbetx20客户端下载 低迷的方式，本质上都是同样的凯恩斯(Keynes)主义。他们允许财政赤字扩大，并通过降息刺激总需求。尽管凯恩斯几乎没有预见到宏观工具会被如此重复地使用，但这些政策的确奏效了。因此，当前这场危机的应对政策“几乎大同小异”。许多政策制定者仍然相信，这些政策最终将创造持续的复苏。不过，我们有必要反思一下，为何它们这次有可能失效，以及还有什么其它公共政策可能有助于推动复苏。简言之，什么是B计划（即“备用方案”）？
