And then, they are integrated at order one I(1). And then, the variables are
eligible to test the long run cointegration analysis between them.
a. Trace, max-eigen and Pedroni tests of cointegration
Trace and max-eigen tests
According to Trace test, one (1) cointegrating equation at the level
of 5% were accepted. The P-values from trace test and max-eigen
statistic are significant at 5% level. This shows existence of a long-run
relationship between X, HDI and IQ.

Predroni test
Pedroni (2004) is used to test cointegration. And then, as results
shows, four (4) of seven (7) statistics gives by Pedroni test concluded
on existence of cointegration relation between exports, human
resources development and institutional quality. And then, according
to Granger representation theorem, an vector error correction model
(ECM) can be perform.

3. Result
Cointegration equation
Cointegration equation is given by: = −, + ,
On the long term, HDI have negative impact to X, exports and IQ have
positive impact on X.
