intercept in the cointegration space combines with the intercept in the short run model
resulting in an overall intercept contained in the short-run model; (M4) if there exists an
exogenous linear growth not accounted for by the model, the cointegration space includes
time as a trend stationary variable.

Because usually is not known a priori which model to apply, the Pantula principle (Harris
1995) is used to simultaneously test for the model and the cointegration rank.

4. Data and results

The theoretical model developed by Saghaian et al. (2002) serves as a guide for our empirical
work. This model supposes a small open economy which is an appropriate assumption for
Hungary. Monthly time series of an agricultural variable, the log of producer price index
(lnPPI), the log of industrial producer price index (lnIPI), the log of Euro/Hungarian Forint
exchange rate and the log of the seasonally adjusted money supply (M1A) were used. The
dataset presented on figures 1 and 2, covers the January 1997 - August 2004 period,
consisting of 92 observations. Data sources are the CSO-Central Statistical Office, and NBH
- National Bank of Hungary.
