Are Unemployment Statistics Meaningless? Are Spillover Effects Zero?

Casey Mulligan rebuts my post asserting slack in the economy by posing the scenario “Construction Workers Teaching Kindergarten” (Note: Mulligan’s blog is down; here is an alternative link currently working – 8/2/09). He writes:

Econbrowser now claims* that the stimulus bill can be effective, because unemployment rates are high (whatever that means) in health care and education. Let’s take a look at employment changes Dec 2007 – June 2009 (millions) by industry:

 

Total nonfarm payrolls: -6.5

Construction: -1.3

Manufacturering: -1.9

Education and Health: +0.7

How exactly is fiscal policy going to create 3.5 million jobs by primarily hiring people in education and health? I see only two scenarios, both absurd and/or dishonest:

He argues these two scenarios are: (1) “The construction workers become kindergarten teachers” or (2) “The people in construction and manufacturing stay unemployed.”

Looking for an exit: Part 2

In my previous post I commented on Ben Bernanke’s recent communication of the Fed’s exit strategy for getting its balance sheet and daily operations back to historical norms. I suggested that one necessary ingredient to convince the public that we will see a return to a stable monetary regime would be a credible explanation of how the United States government will be able to meet its enormous current and implicit future fiscal obligations. Today I’d like to discuss a second element that I feel is missing from the exit strategy articulated by Bernanke, and this is a compelling vision of what a healthy financial market not propped up by the Treasury and the Fed would look like.

Output Gap Measurement and Prospects in the Wake of the Crisis

Different concepts of potential GDP

For serious macroeconomists, the magnitude (or existence) of the output gap is a central factor for determining the appropriate policy actions (see for instance Weidner and Williams). In several recent posts, I’ve discussed the variety of approaches to estimating the output gap [0] [1]. A recent symposium on Projecting Potential Growth published by the Federal Reserve Bank of St. Louis is an excellent resource for anybody who wants to think seriously and carefully about the challenges in estimating this variable. In the lead article entitled “What Do We Know (And Not Know) About Potential Output?”, the authors Susanto Basu and John Fernald write:

In the news

Russ Roberts, Mark Calabria, and I weigh in on the lessons from CIT at the NYT.

And the WSJ surveys economics blogs. I’ll give away the plot: the one you’re reading rates “five calculators” on the geekiness scale.

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.
