We reconsider the role of reallocation shocks in a simple New Keynesian model with search and matching frictions. The sign of the conditional correlation between unemployment and vacancies depends on the degree of price rigidity and on the persistence of the shock. Therefore, a non negligible role for reallocation shocks in driving business cycle fluctuations cannot be ruled out on theoretical grounds.
