In this paper, henceforth denoted LPS, we analyse the (logarithm of) 
real per capita GDP in 102 non-oil producing countries, and two 
sub-sets of them (an intermediate group of 61 countries and a 
group of 22 OECD countries), using annual data for the period 1960-
1989 (30 observations). The original source of the data is the Penn 
World Tables [PWT] (Version 5.6), dated November 20, 1994. Version 5.0 
of the PWT is described in Summers and Heston (Quarterly Journal of 
Economics, 1991). The measure of per-capita income that we use is 
labelled RGDPL on the PWT.

The data are stored in four files:
 
NAME.LPS contains the names of all of the countries contained in the 
PWT (with country identifiers), plus an explicit listing of the 
countries included in the 102, 61, and 22 country sample used in LPS. 
The file takes 14 kbytes.

Y102.LPS contains the (logarithm) of per-capita GDP for the 102 
country sample over the period 1960-1989. Data is ordered country by 
country (i.e. the 30 observations relating to per-capita GDP in 
country 1 is followed by the 30 observations relating to per-capita 
GDP in country 2, and so on). The file takes 40 kbytes.

Y61.LPS contains the (logarithm of) per-capita GDP for the 61 
country sample over the period 1960-1989, and the data is ordered 
country by country. The file takes 24 kbytes.

Y22.LPS contains the (logarithm of) per capita GDP for the 22 country 
sample over the period 1960-1989 and the data is ordered country by 
country. The file takes 8 kbytes.

These four files, which are in DOS format, are zipped in the file 
lps-data.zip.
