Finished the new and improved EPI!
I just finished constructing a new and improved Export Price Index for U.S. counties and cities. The EPI is a Laspeyres-type price index measuring the terms of trade of a region. The weights are from QCEW data, and the prices come from PPI (SIC), PPI (NAICS), PPI (Commodity), and the CPI (urban consumers).
