Over at EconLib.org, Michael Munger reviews Alesina et.al. Here's an excerpt:
"So, austerity is a second best policy, contingent on a particular kind of government failure. Alesina et al note that the effectiveness of austerity is controversial, with the discussion in the press “often taking a very ideological, harsh, and unproductive tone.” (page 3) The reasons given for why austerity should be selected by a government, or should be imposed as a condition of extension of loans by creditors, are obvious: (a) the ratio of debt to GDP has grown perilously large, raising questions about whether even the existing debt can be repaid, and (b) crises, fiscal needs arising from wars or major economic downturns in the business cycle or in currency exchange markets.
The critics claim that austerity is a moralistic, punitive policy designed to cause pain for excess deficits, one that fails even on its own logic because it actually pushes debt to GDP ratios higher rather than lower. The argument is that GDP shrinks sharply as government spending is cut, and even if debt falls, GDP falls by more which worsens the problem and causes an economic storm.
In a way, that’s the end of the story. Because Alesina, et al. are able to give a decisive resolution to the controversy: not all austerities are the same. In fact, there are two very different types: a focus on raising taxes, and a focus on cutting spending. When it comes to imposing an austerity of “sharply increased taxes” variety, the anti-austerity activists probably have the best of it. But when the austerity takes the form of large-scale cuts, not just in budgets but in entire programs, the larger weight of evidence by far falls on the “austerity works” side of the scale."Read the whole review here.
