The recent volatility in global commodity prices and in the price of oil, in particular, has created renewed interest in the question of how monetary policy makers should respond to oil price fluctuations. In this paper, we discuss why this question is ill-posed and has no general answer. The...

The paper investigates the impacts of the volatility of monetary policy on the economy in a DSGE model with financial frictions a la Bernanke, Gertler, and Gilchrist (1999). The model is estimated by the particle filter maximum likelihood estimator for the U.S. economy. Our results first show...

We employ a structural VAR model with global and US variables to study the relevance and transmission of oil, food commodities, and industrial input price shocks. We show that commodities are not all alike. Industrial input price changes are almost entirely endogenous responses to other shocks....
