In this paper we provide short- and long-run tax buoyancy estimates for 107 countries (distributed between advanced, emerging and low-income) for the period 1980–2014. By means of Fully-Modified OLS and (Pooled) Mean Group estimators, we find that: i) for advanced economies both long-run and short-run buoyancies are not different from one; ii) long run tax buoyancy exceeds one in the case of CIT for advanced economies, PIT and SSC in emerging markets, and TGS for low income countries, iii) in advanced countries (emerging market economies) CIT (CIT and TGS) buoyancy is larger during contractions than during times of economic expansions; iv) both trade openness and human capital increase buoyancy while inflation and output volatility decrease it.
This Selected Issues paper estimates the path of the equilibrium real exchange for Malawi. Based on a dynamic model of a small open economy, the paper identifies and discusses the dynamics between certain fundamental variables and the real exchange rate. It also investigates the presence of a long-term relationship between the real exchange rate and the explanatory variables, and estimates both the equilibrium real exchange rate and the speed at which it converges toward its equilibrium level. The paper also discusses episodes of discrepancies between the real effective exchange rate and its equilibrium level.
