This paper uses a simple dynamic stochastic general equilibrium model to explore the qualitative impact of productivity shocks on current account positions via their impact on the saving behaviour of households. The analysis shows that the direction of the impact is ambiguous from a theoretical point of view. This impact depends in particular on consumer’s willingness to shift consumption over time relative to their willingness to shift consumption between different types of goods, on whether they believe the shock to be temporary or permanent, and on the sector in which the shock occurs.
