Natalia Bailey, George Kapetanios, and M. Hashem Pesaran (2021), "Measurement of Factor Strength: Theory and Practice", Journal of Applied Econometrics, Vol. 36, No. 5, 2021, pp. 587-613. All files are zipped in the (rather large!) file bkp-files.zip. Contrary to the usual practice of the JAe dATA archive, the data are stored in .xls files. The directory structure within bkp-files.zip is Procedures/ Procedures/Empirics/ Procedures/Simulations/ Results/ Results/Empirics/ Results/Simulations/ Monte Carlo simulations (procedures and results): (Section 5 of BKP 2021 paper and Supplementary Appendix E) All Gauss procedures corresponding to the experiments of Section 5 of BKP 2021 main paper can be found in Procedures\Simulations. These are: File: "mc_FS1A.prg" File: "mc_FS1A_Power.prg" File: "mc_FS1B.prg" File: "mc_FS1B_Power.prg" File: "mc_FS2A.prg" File: "mc_FS2A_Power.prg" File: "mc_FS2B.prg" File: "mc_FS2B_Power.prg" File: "mc_FS3Aa.prg" File: "mc_FS3Aa_Power.prg" File: "mc_FS3Ab.prg" File: "mc_FS3Ab_Power.prg" File: "mc_FS3B_PC.prg" File: "mc_FS3Ba_CSA.prg" File: "mc_FS3Bb_CSA.prg" File: "mc_FS3Bc_SeqCSA.prg" File: "mc_FS4a.prg" File: "mc_FS4b.prg" The names of these files correspond to the names of the experiments in Section 5 of BKP 2021 main paper. The description of each experiment and the corresponding Tables/Figures in the paper are provided at the top of each .prg file. The content of all results tables and figures for the experiments of Section 5 of BKP 2021 shown in the main paper and Supplementary Appendix E can be found in Results\Simulations. These are: File: FS_MC_tables.xlsx File: power_matlab.xlsx Empirical Applications (procedures and results): (Section 6 of BKP 2021 paper and Supplementary Appendix D) The Gauss procedures corresponding to the financial and macroeconomic applications of Section 6 of BKP 2021 main paper can be found in Procedures\Empirics. These are: File: "aFS_finance.prg" File: "aFS_macro.prg" Data Description: Subsection 6.1: Identifying risk factors in asset pricing models The S&P500 data (345 xls files for returns (SPi.xls, for i=1,2,...,345) plus 2 files that include risk factors (Mkt_RF2.xls) and interest rate (RF.xls) data) can be found in Procedures\Empirics. These data read into the Gauss file: "aFS_finance.prg" Subsection 6.2: Stength of common macroeconomic shocks The macroeconomic data (FRED_QSWf.xls) can be found in Procedures\Empirics. The raw data, which include both high-level economic and financial aggregates as well as disaggregated components, can be found on the Federal Reserve Bank of St Louis website at: https://research.stlouisfed.org/econ/mccracken/static.html. The data in file: "FRED_QSWf.xls" read into the Gauss file: "aFS_macro.prg" Output: Output from "aFS_finance.prg" for the financial empirical application of Sub-section 6.1 of BKP 2021 paper can be found in Results\Empirics. All results and further computations can be found in file: "FS_empirics_tables_figures.xlsx". Each sheet is named after the table or figure in the main BKP 2021 paper or Supplementary Appendix D that the results correspond to. Output from "aFS_macro.prg" corresponds directly to the content of Table 5 of BKP2021 main paper.
