Cheng Chou and Ruoyao Shi, "What Time Use Surveys Can (And Cannot) Tell Us About Labor Supply", Journal of Applied Econometrics, Vol. 36, No. 7, 2021, pp. 917-937. All files are zipped in chou-shi-files.zip. Data files are in the folder "data", and program files are in the folder "programs". Some data files are in binary format. All program files and one ".txt" data file are in DOS format. ----------- DATA SOURCE ----------- All data were downloaded from IPUMS Time Use (https://timeuse.ipums.org) and cleaned by following the procedure described in our paper. ---------- DATA FILES ---------- The data for the simulation results (Table 1) are in ".txt" format. The data for the empirical results (other tables and figures) are in ".rds" format, which can be read by R (a free software) using `readRDS` command. Using the R package `ipumsr` developed by IPUMS team, one can directly view the variable and value labels, which will be lost if ".rds" files are exported as ".csv" files. For example, to view the variable label of the variable "METRO", do the following: ``` atus <- readRDS("atus.rds") library("ipumsr") ipums_var_label(atus, "METRO") ``` - "mtus.txt" is used to produce "Table 1: Simulations Based on the Dutch Time Use Survey (DTUS)". - "dtus.rds" is used to produce "Table 2: Weekly Labor Supply Elasticity Estimates (Hundredths): the DTUS". - "dtusPlotRandomDailyHours.rds" is used to create "Figure 1: DTUS Weekly Hours vs. Randomly Drawn Daily Hours × 7". - "dtusPlotMeasurementError.rds" is used to produce "Figure 2: Measurement Errors in the DTUS Recalled Weekly Hours Worked". - "atus.rds" is used to produce "Table 3: Weekly Labor Supply Elasticity Estimates: the CPS and the ATUS". ----------------- Computer Programs ----------------- - "simulations.m" produces Table 1. It is a Matlab file. It relies on our programs "est.m" and "est5.m", which are estimation routines. The simulation results will be saved as "simulations.mat". - "dtus.R" produces Table 2, Figure 1 and Figure 2 in the paper. Users should set their working directory to the one immediately containing "dtus.R", "estimators.R", "atus.R", and the aforementioned data files. This program will produce the following items: * "DTUSKidsParameters.tex" is a LaTeX table of the weekly labor supply parameters (not elasticities) estimates using the DTUS. * "DTUSKidsElasticities.tex" is a LaTeX table of the weekly labor supply elasticities estimates using the DTUS. This is Table 2 in the paper. * "DensitiesWeeklyRandomDaily7.png" is Figure 1 in the paper. * "CorrelationDensityMeasurementError.png" is Figure 2 in the paper. - "atus.R" produces Table 3 in the paper. The output is a LaTeX file "atusElasticity.tex" reporting "Table 3: Weekly Labor Supply Elasticity Estimates: the CPS and the ATUS". - "estimators.R" contains various utility functions, e.g., estimation routines, variance estimators etc. ----------------- Online Appendices ----------------- - "TimeUse_Appendix.pdf" contains additional simulation and empirical results and proofs, and it can be linked to the paper on the JAE website.
