This must be the period of soul searching, with the Economist engaging upon multi-article exegeses on where mainstream macro went wrong [1], [2], [3]. Alternatively, I think this is a happy time for some economists outside the (perceived) mainstream, who can now chortle “I told you so”. One recent example is by Mario Rizzo.

Casey Mulligan on the Stimulus: Stock-Flow Mismatch, Sectoral Stimulus Mismatch, and Construction Crowding Out
In today’s Economix post, Casey Mulligan argues that the greater than predicted unemployment numbers should not be ascribed to the negative effect of the stimulus, but rather to bigger than anticipated negative shocks.
We cannot blame the Obama administration for failing to predict June’s 9.5 percent unemployment rate. That result just shows the size of the shocks hitting the economy: Even the best forecasters can miss the unemployment rate by almost two percentage points, even when forecasting fewer than six months ahead.
A New Survey of Multipliers
For people who want an impartial survey of multipliers, see Patrick Van Brusselen, “Fiscal Stabilisation Plans and the Outlook for the World Economy”. It’s a useful antidote to the blogposts that cherry-pick multipliers from a given model to make a given point. The survey ranges over US, euro-area, and Japan; and structural macroeconometric models, DSGEs, and VARs.
Ed Lazear on the Stimulus Package
From the WSJ editorial page:
Only a small share of the spending will occur in 2009, even though Keynesians would argue that stimulus spending should be frontloaded to kick-start growth. The Congressional Budget Office estimates that the largest share of the spending will occur in 2010, with the amount in 2011 being slightly larger than in 2009. Again, the timing exacerbates the problem: It will be tough to cut back on spending written into budgets as far out as 2011.
Back to the Stimulus Debate: W, Timing, the States, and Baselines
A “W” Recession?
Martin Feldstein has recently raised the possibility that we might experience a relapse into recession (a beautiful symmetrical W), with the next dip in 2010. In my view, this means (1) we should have opted for a bigger and better composed stimulus package, and (2) the timing of expenditures in the stimulus package might not be as problematic as many commentators have indicated. From Bloomberg:
Relevant and Irrelevant Criticisms of the Stimulus Package
Keith Hennessey critiques the stimulus package. Some points make sense, some points, well, I wonder. For instance, Hennessey argues the stimulus is not timely. As I’ve noted before, it’s not timely only if you think this will be a relatively short recession, characterized by a rapidly dissipating negative output gap. [0] [1] [2].
The Allocation of Stimulus Funds
From Daniel Wilson, “Are Fiscal Stimulus Funds
Going to the ‘Right’ States?” at the SF Fed (h/t Torsten Slok at DB):
…While
it is too early to tell whether the overall stimulus
package will have its intended effects, this review
suggests that, by and large, the distribution of federal
stimulus funds is indeed tilted toward those states most
likely to spend the funds quickly and effectively.
The Stimulus Package Considered against a Deteriorating Macro Backdrop
Here are the latest CBO forecasts of the output gap and unemployment rate, as well as counterfactual gap and rate that would have taken place in the absence of the stimulus package.
The Great Multiplier Debate, New Keynesian Edition
Greg Mankiw cites a study by Cogan, Cwik, Taylor, and Wieland to buttress his arguments that fiscal multipliers are small, especially when considering New Keynesian models. He also provides a startling graphic showing the dynamic multipliers from Romer-Bernstein versus the Taylor (1993) model, incorporating model consistent expectations; this graphic motivates Wieland et al. to remark:
We first show that the assumptions made by Romer and Bernstein about monetary
policy — essentially an interest rate peg for the Federal Reserve — are highly questionable
according to new Keynesian models. We therefore modify that assumption and look at the
impacts of a permanent increase in government purchases of goods and services in the
alternative model. According to the alternative model the impacts are much smaller than
those reported by Romer and Bernstein.
Cogan et al. use a New Keynesian dynamic stochastic general equilibrium (DSGE) model, specifically the Smets-Wouter model (Working Paper version of AER paper here).
Recap: The Stimulus Bill and the Macro Impact
CBO has now released an analysis of spend rates of the final stimulus bill to be signed by the President on Tuesday. While the proportions of expenditures and tax cuts are changed, the time profile is little changed from the original House bill — wherein most of the stimulus takes place in the next 19.5 months.
