DATA

OWW3 database

Stata (self-extracting, original)

Stata (uncompressed)

ASCII comma-separated variables

oww3.zip (4.1 Mb)

oww3.dta (19.4 Mb)

oww3.csv (47.9 Mb)

oww3.asc (47.9 Mb)

You will need a major database, statistical program, or programming language to use these files. This dataset is too large to load completely into MS Excel 2000, which has a maximum of 65,536 observations, though Access can be used to read the ASCII datafile. Users without STATA may be interested in STAT/TRANSFER. This program can translate STATA files into other formats including other statistical packages, database packages and spreadsheets. Among statistical packages supports are SPSS, SAS, and Systat.

Calibration Info

Wage data are reported with variable names PwTwW_C, where P indicates whether it is an hourly or monthly wage, the calibration type, W the weighting type, and C the currency type:

P∈{h,m}

Period:

h = hourly wage

m = monthly wage

T∈{1,2,3,4}

Type:

1 = standard data (no calibration)

2 = country-specific calibration

3 = country-specific calibration with imputation

4 = uniform calibration

W∈{l,u}

 Weighting:

l = lexicographic weighting

u = uniform weighting

C∈{current,present,us}

Currency:

current = in reported LCU

present = in present-day LCU

us = in US$

It is recommended to start any analysis conservatively with the non-calibrated data w1 and next to use the standardized data w2 and w3 (with increasing levels of data calibration / imputation). The standardized wage with country-specific calibration and imputation and lexicographic weighting (w3wl) is recommended for use because it provides the largest sample, it uses country-specific calibration to the extent possible and it uses lexicographic weights favoring raw data reported in standard format. The standardized data w4 do not use country-specific calibration and correspond to the standardization variant 2 in the initial release of the data for 1983-1998 (see NBER Working Paper 8058, table A.1). It is included for comparison.
