Few endogenous growth models are able to encompass unbalanced transitional dynamics. In Barro (1990) public spending is a productive externality and growth is only regular. The second best tax rate equals the public spending return. We provide a monetary version of Barro (1990), where short-run fluctuations are due to money and long-run effects to technology. Barro’s rule is found to be surprisingly robust within transition.
