*** denotes 0.01 significance level, ** 0.05 significance level, * 0.10 significance level. The R-squared and the
diagnostics are based on the long-run form, also known as the Error Correction form. (Detailed results are available
at the appendix; see tables 6-9).

*** denotes 0.01 significance level, ** 0.05 significance level, * 0.10 significance level. The short-run ARDL is a 1,3,2,2,0.
The ordering of the variables, in relation to the reported lags, is as stated on the table above. Moving to joint
significance under the Wald test, C(2)−C(5) on Unemployment, C(6)−C(8) on interest rates, and C(9)−C(11) on GDP. C
(1) is the lagged NPL and C(13) are the Gross loans C(12) and are insignificant (available at the appendix). Also,
Residual and Stability diagnostics are consistent with the econometric expectations and this model is robust as well
(for more details see the Appendix; Tables 10-11, respectively).
