N. Crato et P. Rothman, FRACTIONAL-INTEGRATION ANALYSIS OF LONG-RUN BEHAVIOR FOR US MACROECONOMIC TIME-SERIES, Economics letters, 45(3), 1994, pp. 287-291
We apply a new ARFIMA approach to distinguish between the trend and di
fference stationary models of long-run dynamics for a well-known repre
sentative macroeconomic dataset. Our results strengthen the case for t
he difference stationary model for these series.
