The choice of deflators of commodity prices can change the time-series properties of the original series. This is a specific application of the general phenomenon that various kinds of data transformations can create spurious cycles that did not exist in the original data. Different empirical...

A rational expectations competitive storage model is applied to the U.S. corn market to assess the aptness of this framework in explaining monthly price behavior in an actual commodity market. Relative to previous models, extensive realism is added to the model in terms of how production...

Vector autoregression (VAR) methods are used to analyse the contribution of supply, demand and policy shocks to unpredictable fluctuations in the market for Australian wool. VAR procedures are compared with conventional structural econometric models as methods for decomposing sources of...

Empirical models of commodity prices are potentially important aids to decision-makers, especially as the economy has grown more complex. A typical time series of commodity prices exhibits positive autocorrelation, occasional spikes, and random variability, and conceptual models have been...

The value of the timing option implicit in CBOT corn futures contract is estimated. Separate estimates are obtained for the option without and with convenience yield. The effect of the option on basis behavior at day one of the maturity month is examined and is found to be statistically important.

Numerous models of price-demand-supply behavior in agricultural markets have been proposed and estimated. The literature contains valuable contributions, but the cumulative effect is somewhat disappointing. This paper appraises the status of the price analysis literature and makes suggestions...
