This working paper contrasts the neo-Keynesian and post-Keynesian theories of monetary policy for an open economy, highlighting the irrelevance of the orthodox theory and the explanatory capacity of heterodoxy for an emerging economy such as Mexico. It focuses on the role of the central bank and the case of the Mexican currency during the economic recovery after the Great Lockout. In the first section, we criticize two proposals of the 3-Equation New-Keynesian model, concluding that, implicitly, both models reaffirm the extreme neutrality of money and the exchange rate in both the short and the long runs. In contrast, we analyze the post-Keynesian exchange rate model proposed by John T. Harvey (2009). In addition, we rely on the fundamentals of the heterodox school of thought such as the financial instability hypothesis of Hyman Minsky (1994) and the relevance of capital flows for the determination of the exchange rate and its implications for economic growth and prices by Jan Kregel (2008). Finally, the erratic behavior of the excessive appreciation of the Mexican Super Peso against the dollar after the recovery of the COVID-19 crisis and in the context of global risk is presented.

For Matías Vernengo and Esteban Pérez Caldentey (2020), the MMT literature overemphasizes the choice of the exchange rate regime and the relevance of a flexible exchange rate regime, as well as the ultimate effect of that choice upon the policy space. In addition, they argue that the role of capital flows is underexplored, and that the relevance of the balance-of-payments constraint is often underestimated. Vernengo and Pérez’s criticism fails to consider that exchange-rate flexibility makes it possible to use flexible fiscal and monetary policies as well, to boost growth and employment, and to reduce the balance-of-payments constraint.

A Theoretical Framework

Liabilities denominated in foreign currency have established a permanent role on emerging market firms’ balance sheets, which implies that changes in both global liquidity conditions and in the value of the currency may have a long-lasting effect for them. In order to consider the financial conditions that may encourage (discourage) structural change in a small, open economy, we adopt the framework put forward by the “monetary theory of distribution” (MTD). More specifically, we follow the formulation adopted by Dvoskin and Feldman (2019), whereby the financial system is intended as a basic sector that promotes innovation (Schumpeter 1911). In accordance with this, financial conditions are binding only for the innovative entrepreneurs, whose methods of production are not dominant and hence they need to borrow from banks to kickstart their production. Through this device, our model offers an explanation of the technological lock-in experienced by a small, open economy that takes international prices as given.

A Stock-Flow Consistent Framework for Mexico

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.
