NEARBY SUPPLIERS BY TYPE AND BY MARKET
For each market in our sample, Appendix E identifies each of the three types of nearby suppliers with the prefix PT, NPT, or NDL where
PT = pass-through pipeline,
NPT = nearby pass-through pipeline, and
NDL = nearby delivery pipeline.
Current suppliers are listed without a prefix. For a further explanation of this appendix refer to Chapter 4, subsection "Limitations of the Short-Run Analysis."
