Oil Price Shocks and Current Account Imbalances within a Currency Union.

The article analyzes the impact of oil price shocks on current account imbalances within a currency union, specifically focusing on the Eurozone with its asymmetric labor market institutions. Using a two-country dynamic stochastic general equilibrium (DSGE) model incorporating search and matching labor market frictions, the study finds that oil price shocks can cause persistent internal imbalances due to sluggish wage and price adjustments. Monetary policy targeting consumer price index (CPI) inflation tends to stabilize prices, output, and employment but may exacerbate current account imbalances, whereas targeting core CPI inflation reduces imbalances at the cost of higher unemployment and lower production. The research highlights that increasing labor market flexibility—through reforms reducing firing and vacancy posting costs—can mitigate the adverse effects of oil price shocks and improve the currency union’s internal adjustment mechanisms, suggesting labor market reforms as a complementary policy to monetary strategies in managing such shocks.
