Adoption of Inflation Targeting and Economic Policies Performance in Emerging Countries: A Dynamic Treatment Effect Evaluation

This chapter attempts to analyze mainly the interactions between the implementation of inflation targeting (IT) policy and performance in the conduct of economic policies (fiscal and exchange rate) in emerging countries. More precisely, empirical studies conducted in this chapter aim to apprehend the feedback effect of this strategy of monetary policy on the budget deficit and volatility of exchange rate performance. This said, we consider the institutional framework as endogenous to IT and analyze the response of authorities to the adoption of this monetary regime. To do this, the retained methodological path in this chapter is an empirical way, based on the econometrics of panel data. First, our contribution to the existing literature is to evaluate the time-varying treatment effect of IT’s adoption on the budget deficit of emerging inflation targeters, using the propensity score matching approach. Our empirical analysis, conducted on a sample of 34 economies (13 IT and 21 non-IT economies) for the period from 1990 to 2010, show a significant impact of IT on the reduction of budget deficit in emerging countries having adopted this monetary policy framework. Therefore, we can say that the emerging government can benefit ex post and gradually from a decline in their public deficits. Retaining the same econometric approach and sample, we tried secondly to empirically examine whether the adoption of IT in emerging inflation targeters has been effectively translated by an increase in the nominal effective exchange rate volatility compared to non-IT countries. Our results show that this effect is decreasing and that this volatility is becoming less important after the shift to this monetary regime. We might suggest that this indirect and occasional intervention in the foreign exchange market can be made by fear of inflation rather than by fear of floating hence in most emerging countries that have adopted the IT strategy. Finally, we can say that our conclusions corroborate the literature of disciplining effects of IT regime on fiscal policy performance as well as the two controversial effects of IT on the nominal effective exchange rate volatility.
