Spillover dynamics across price inflation and selected agricultural commodity prices

Commodity Prices, Convenience Yields, and Inflation

This paper provides evidence that the two leading principal components in a panel of 23 commodity convenience yields have statistically and quantitatively important predictive power for inflation even after controlling for unemployment gap and oil prices. The results hold up in out-of-sample forecasts, across forecast horizons, and across G7 countries. The convenience yields also explain commod...

Mean and Variance Dynamics between Agricultural Commodity Prices and Crude Oil Prices

Volatility and Commodity Price Dynamics

Commodity prices tend to be volatile, and volatility itself varies over time. Changes in volatility can affect market variables by directly affecting the marginal value of storage, and by affecting a component of the total marginal cost of production: the opportunity cost of exercising the option to produce the commodity now rather than waiting for more price information. I examine the role of ...

Predictive Dynamics in Commodity Prices

Using a sample of commodity spot price indexes over the period 1947-2010, we examine predictability of commodity returns at the monthly, quarterly, and annual horizons. We establish out-of-sample predictability by means of variables such as bond spreads, growth in money supply and industrial production. Predictability is strongest for raw industrials and metals indexes and weakest for foods and...

Discussion of Determinants of Agricultural and Mineral Commodity Prices

It is a pleasure to be invited to discuss this rich paper by Jeffrey Frankel and Andrew Rose. After the events of the past few years, with a range of commodity prices exhibiting great volatility, it is not hard to motivate Frankel and Rose’s choice of topic, seen from either a longor medium-term perspective. The authors use annual data, mainly in a panel context, to examine the relationship bet...
