I. Introduction•Crises of ortodox monetary policies: •Monetarist experiment (1970s-1980s) (Kaldor, 1970, 1979, 1986; Desai, 1981; Moore, 1986).•Rational Expectations experiment (1980s-1990s)•Collapse of fixed exchange rate regimes (1980s, 1990s, 2000s).

•Main message of the paper:•According to our empirical findings, there doesn’t seem to be a positive relationship b’n the real exchange rate (q) and GDP during the period under scrutiny (1960-2010) in Brazil, South Korea and Mexico.•Heterogenous effects of q on Consumption, Investment and exports in each different country. •Ergo, not possible to recommend a general policy for all countries without taking into account the specific structure of the economy under consideration before we can predict the effect of real exchange rate fluctuations.

• 1987-1992: gradual drop of M aggregates.• “we did not abbandon monetary aggregates;
instead, they did abbandon us” (a curious central banker).
• Hence inflation targeting (Taylor, 2001; Woodford, 2003; Svensson, 2007).
• Old wine in new goatskins (Wicksell, 1898).

• The new monetary consensus (IT monetary policy frameworks):•It is said to diminish inflation and guarantee long-run price stability through interest rate reaction functions with no intermediate targets whatsoever.
•Yet, the role of real exchange rates in IT monetary policy strategies:Fear of floatingExchange market sterilised interventions

•The role of the exchange rate as a nominal anchor for inflation tends to appreciate the currency.•To be sure, the exchange has played an outstanding role in IT models.•However, it has been said, this may entail negative effects on growth and employment (cf. Frenkel, Ros, Bresser-Pereira, Rapetti, López, Sánchez and Spanos).

• .(15) • Condition (15) implies that a currency
devaluation will bear a positive impact on growth if and only if the positive impact on exports is greater than the negative impact on aggregate demand due to the reduction in real wages.

•.(16) .
Condition (16) means that an increment (diminution) in nominal wages will increase (diminish) effective demand if and only if the negative (positive) effect on exports is compensated by the positive (negative) effect of an increasing wage on aggregate demand.

V. Conclusions and final remarks
1. Expansionary effects or contractionary effects of devaluations?

V. Conclusions and final remarksNo positive relationship b’n real
exchange rate and output in Brazil and Mexico.
Therefore, the contractionary effects of IT should be found elsewhere.
Fiscal policy, for instance (there is a positive relationship b’n fiscal policy and growth).
Swan (1955).
