Daniel Kaufmann, "Is Deflation Costly After All? The Perils of Erroneous Historical Classifications," Journal of Applied Econometrics, Vol. 35, No. 5, 2020, pp. 614-628. All files are zipped in the file dk-files.zip. It contains four main folders: Data, Functions, Programs, and Results. Most files are ASCII text files in DOS format. However, there are also one data file in R format and numerous PDF files. Unix/Linux users should therefore exercise care. Using "unzip -a" might have very bad consequences for the non-ASCII files. Notes Files with the extension *.R run in R (v. 3.6.1) and RStudio (v. 1.2.5019). Files with the extension *.do run in Stata (v. 15). The GMM estimates are based on iterative procedures that may require to increase the number of iterations in the program (see options in the Stata files) Data BLSData.RData BLS CPI subindices to construct the modern replications CompositeCPIMeasuringWorth.csv Composite CPI by Officer and Williamson (2016), www.measuringworth.com RawDataProxy.csv PPI data by Warren and Pearson (1933) linked with modern replications by Hanes (2006) RawData[Country].csv Historical data for various economies. See Online Appendix B6 for a detailed description Programs 1_SimulatePlim.R -> Fig. 1, Fig C.1 R program simulating the probability limit under various assumptions on the measurement errors. 2_RomerizeBLSData.R -> Fig. 2, Tab. 1, B4, B5, DataForStataUS.xlsx Uses BLSData.RData (Alternatively uses original BLS data downloaded from internet as well as RawDataUS.csv, CompositeCPIMeasuringWorth.csv and RawDataProxy.csv); see Online Appendix B3 for a detailed description. Computes the replication and the proxy for the US with historical and modern data. In addition, prepares the US data set for the Stata programs. 3_ConstructStataData.R-> Fig. B2, DataForStata[Country].xlsx Uses RawData[Country].csv. Imports the international data sources (see Online Appendix Tab. B6) and constructs data sets used in the Stata programs. 4_ResultsUS.do -> Tab. 2, Tab C.3 Uses DataForStataUS.xlsx. Computes the results using US industrial production growth. 5_ResultsUK.do -> Tab. 3 Uses DataForStataUK.xlsx. Computes the estimates for various real activity measures for the UK. 6_ResultsCrossCountry.do-> Fig. 3, C.2, C.3 Uses DataForStata[Country].xlsx. Computes the cross-country results (main results and robustness tests). 7_SimulatedData.do -> Tab. 4 Uses DataForStataUS.xlsx. Computes the results with simulated error-ridden data. 8_ResultsRobust.do-> Tab. C.1, C.2, C.3, D.1, D.2, D.3, D.4 Uses DataForStataUS.xlsx. Computes various robustness checks for the US. 9_RobusntessGrid.do -> Fig. D.1 Uses DataForStataUS.xlsx. Computes the robustness tests for various assumptions on the misclassification rates.
