International financial integration has greatly increased the scope for changes in a country’s net foreign asset position through the “valuation channel” of external adjustment, namely capital gains and losses on the country’s external assets and liabilities. We examine this valuation...

This paper describes the result and the methodology of updating the IMF's nominal and real effective exchange rate weights on the basis of trade data over 1999-2001. The underlying framework is an updated version of the IMF's current effective exchange rate calculation, which uses weights...

The time series fit of dynamic stochastic general equilibrium (DSGE) models often suffers from restrictions on the long-run dynamics that are at odds with the data. Relaxing these restrictions can close the gap between DSGE models and vector autoregressions. This paper modifies a simple...

This Paper suggests that skill accumulation through past work experience, or ‘learning-by-doing’ (LBD), can provide an important propagation mechanism in a dynamic stochastic general equilibrium model, as the current labour supply affects future productivity. Our econometric analysis uses a...

This paper assesses biases in policy predictions due to the lack of invariance of ``structural'' parameters in representative-agent models. We simulate data under various fiscal policy regimes from a heterogeneous-agents economy with incomplete asset markets and indivisible labor supply....
