Financial integration, productive development and fiscal policy space in developing countries

This paper offers a simple, tractable post-Keynesian model, which highlights the importance of structural change and productive development in defining the dynamics of the Real Exchange Rate (RER) and foreign debt in a small open developing economy. The argument is that in countries that keep the capital account open and rely on austerity policies to induce a notional surplus in the Balance of Payment, the RER can hardly be used as a tool aimed at smoothing the impacts of changes in international financial markets (as argued in the classical mac-roeconomic trilemma). In our model, capital flows and fluctuations in the RER endogenously feed back into each other and give rise to medium-term cyclical macroeconomic volatility. Fiscal austerity, supposedly taming external imbalances, exacerbates such instability. More diversified productive structures and stronger non-price competitiveness open more space for expansionary fiscal policies, make the economy more resilient to finance-led macroeconomic cycles and make external debt more sustainable. Capital controls, together with stronger price sensitivity of net exports, can further stabilize the economy. The paper carries important policy implica-tions, in particular for the combination of industrial and macroprudential policies in peripheral economies, whose pattern of specialization is highly dependent on a few low-tech commodities. The adoption of industrial policies to foster non-price competitiveness and diversification is critical to sustaining macroeconomic stability, both in the short and the long run.
