On the blogs

Crowding In and the Paradox of Thrift -- Krugman praises Blanchard and the IMF research department. He too has rediscovered, but it was a few years back in his case, the accelerator. No word from him on why then all IMF policy advice is based on supply side reforms and why Blanchard thinks the priority in the US is fiscal consolidation. My take here. Note that here you have the typical organized hypocrisy story, the research department says reasonable things (accelerator), while the policy advice continues to be the same.

The economist's manifesto -- Tim Harford ask economists for policy advice. Often a terrible idea. Proposals are to abolish national insurance entirely (in my view the worst of all proposals) and replace it with higher rates of income tax, increase property taxes, to spend more on urban development, and R&D and infrastructure. Wren-Lewis proposes a rule for monetization of fiscal deficits when interests rates are at the zero bound. Not too bad.

What Causes Recessions? -- Noah Smith gives the traditional New Keynesian answer, shocks and price rigidities. No mention of endogenous cycles, meaning those that result from the normal functioning of the system. On that go here.
