Using the vector autoregression (VAR) models, Schmidt-Hebbel and Werner (2002)
compare three IT countries – Brazil, Chile and Mexico – by estimating the Taylor Rule
equations. They find mixed evidence. Brazil exhibits a statistically significant association
with the expected inflation gap, but Chile responds significantly to the output gap. They
also find that the lagged level of trade surplus significantly leads to a decline in the real
interest rate in most cases, and that these countries continue to response to exchange rate
changes in the short term. Similarly, DeMello andMoccero (2008) find that IT has been
associated with stronger and persistent response to expected inflation in Brazil and Chile,
but only Mexico responds significantly to the changes of nominal exchange rate
