factor is being reduced with high domestic inflows, thus foreign investors are apt to invest in<br />

such a country.<br />

Never<strong>the</strong>less, it is impossible to pronounce which one <strong>of</strong> <strong>the</strong>se variables causes FDI since<br />

relationship between factors does not mean causality <strong>of</strong> one variable on ano<strong>the</strong>r. To be more<br />

effective in policy making, it is hence imperative to look at <strong>the</strong> causality aspect <strong>of</strong> each <strong>of</strong><br />

<strong>the</strong>se determinants on FDI made possible through <strong>the</strong> cointegration and VAR/VECM model.<br />

The latter are also very useful on addressing <strong>the</strong> issues <strong>of</strong> dynamics and endogeneity in FDI<br />

modeling.<br />

COINTEGRATION AND VAR/VECM<br />

Since variables have already been for tested before for stationarity, <strong>the</strong>ir first differenced<br />

form shall be used for <strong>the</strong> VAR model to check for cointegration and fur<strong>the</strong>r, causality.<br />

Using <strong>the</strong> Johansen test for Cointegration confirmed <strong>the</strong> existence <strong>of</strong> co integration and a<br />

VECM is this employed to better capture and predict results about causality. The ECT (from<br />

Johansen procedure) is used toge<strong>the</strong>r with current and past differenced values <strong>of</strong> FDI<br />

determinants to get speed <strong>of</strong> adjustment.<br />
