Finally, we analyze the implications of our estimations on exchange rate pass-through by
simulating an unexpected permanent 10% shock to the nominal exchange rate18. In order
to do so, besides using the estimated equation (first column in Table 2), we assume fully
indexed wages. Thus, we solve the model (not estimate it) simultaneously, by also
including the following equation: wt = wt-1 + Dpt-1, for both private and public sectors,
respectively. After we introduce a shock to the nominal exchange rate, we compute the
pass-through effect using the simulated paths followed by both the nominal exchange rate
and domestic prices. It is worth noting that the exercise does not consider any monetary
policy action.
