Demonstrating the Equivalence Result
Here, we show how various detailed models with underlying distortions are equivalent to a prototype growth model with one or more wedges.
The Accounting Procedure
Having established our equivalence result, we now describe our accounting procedure at a conceptual level, discuss a Markovian implementation of it, and distinguish our procedure from others.
Our procedure is designed to answer questions of the following kind: How much would output fluctuate if the only wedge that fluctuated is the efficiency wedge and the probability distribution of the efficiency wedge is the same as in the prototype economy? Critically, our procedure ensures that agents’
Applying the Accounting Procedure
Now we demonstrate how to apply our accounting procedure to the Great Recession and postwar data for the United States and a group of other OECD countries. (In Appendix, we describe in detail our data sources, parameter choices, computational methods, and estimation procedures.)
Conclusion
We have elaborated on the business cycle accounting method proposed by CKM, cleared up some misconceptions about the method, and applied it to compare the Great Recession across OECD countries as well as to the recessions of the 1980s in these countries.
We documented four findings. First, with the notable exception of the United States, Spain, Ireland, and Iceland, the Great Recession was driven primarily by the efficiency wedge. Second, in the Great Recession, the labor wedge plays a dominant
