This paper discusses monetary policy in a New Keynesian open economy subject to commodity price fluctuations. We review theoretical results that imply that stabilizing the producer price index (PPI) is optimal only under special circumstances. In a calibrated version of the model, PPI targeting is compared against a policy that stabilizes a forecast of the consumer price index. The results depend on model specifics, especially elasticities of substitution and the structure of international asset markets.
