Kosei Fukuda, "Age-Period-Cohort Decomposition of Aggregate Data: An
Application to U.S. and Japanese Household Saving Rates", Journal of Applied
Econometrics, Vol. 21, No. 7, 2006, pp. 981-998.

There are two text files: USA.txt and JPN.txt. Each file has two data
sets: One is household saving rates series corresponding to Table III
or Table V, and another is number of households surveyed. Survey periods
are laid out in columns, and age groups are laid out in rows. U.S. and
Japanese data are obtained from the Consumer Expenditure Survey and
from the Annual Reports on the Family Income and Expenditure Survey,
respectively.

Both data files, which are in DOS format, are zipped in the file
fakuda-data.zip. Unix users should use "unzip -a".
