Description of Supplementary
Files for “An Alternative Theory of the Plant Size Distribution, with Geography
and Intra- and International Trade”
by
Thomas J. Holmes (University of Minnesota,
Federal Reserve Bank of Minneapolis, and NBER)
and
John J. Stevens (Board of
Governors of Federal Reserve System)
Note: The statistics
reported in this file are all derived from public Census data
Description of SAS File (ea_CBP07.sas7bdat)
ea×NAICS level data (177
economic areas times 172 diffuse demand NAICS industries). For each industry and location the file
contains the data needed to estimate the model for 2007. The “CBP” stands for
County Business Patterns. The source of
this data is the publicly available County Business Patterns(CBP) data.
One thing to explain is that
the CBP data has cell counts for each county×NAICS for the in size
categories. The CBP size categories are
more disaggregated than the LM categories used for ea_CM97. We aggregate the CBP to the level of the LM
(this combines the 1000-1499 and 1500-2499 into 1000-2499, and the 2500-4999
and 5000 plus into 2500 plus).
Thus we use the same size
categories as described in ea_CM97.html. We use the same values for AVGEMP and S_NORM.

Description of ASCII File (ea_CM97.asc)
This is just like above,
except in ASCII format for reading into Gauss.
In particular, there is no header row there 13 columns of data, where
the columns are the following:
