Abstract
This working paper empirically and theoretically analyzes the exchange rate’s role in Mexico’s
development for the period 2004–19. We test the hypothesis of the re(emergence) of the balance
sheet effect due to an increase in external debt in the nonfinancial corporate sector; higher foreign
debt would affect private investment after episodes of real currency depreciation, in the spirit of the
literature put forward by Gertler, Gilchrist, and Natalucci (2007) and Céspedes, Chang, and Velasco
(2004). We build a stock-flow consistent (SFC) model, following the OPENFLEX model proposed
in Godley and Lavoie (2006), to explore the balance sheet implications from a theoretical
perspective. We simulate the 2014 fall in the Mexican peso generated by the drop in oil prices to
replicate stylized facts for Mexico for the period under investigation. The scenario analysis points to
a hysteresis effect of the real exchange rate (RER) depreciation on investment flows. That is, firms’
investment ratio does not completely recover from negative shocks in the currency.
