This paper provides an assessment of real exchange rate measures and their impact on trade performance with special reference to two Pacific island countries, Fiji and Samoa. The analysis shows that the commonly used CPI-based real effective exchange rate (REER) measure provides a useful...

Structural transformation has resulted in an increasing share of services in aggregate value-added in advanced and developing countries across the world. We analyze the impact of this shift into services on countries' efficiency in collecting the value-added tax (VAT). The analysis is based on...

We use a calibrated multi-sector DSGE model to analyze the likely impact of oil windfalls on the Ghanaian economy, under alternative fiscal and monetary policy responses. We distinguish between the short-run impact, associated with demand-related pressures, and the medium run impact on...
