Storage Under Backwardation: A Direct Test of the Wright-Williams Conjecture
AbstractCommodities are often stored when the spot price exceeds the future price in a central market. Wright and Williams conjectured that inventories are held in locations far from the central market on these occasions. In these locations the spot price is lower than the price for forward delivery because transport costs are temporarily high. This hypothesis has not been directly tested, because prices for forward delivery are not normally available at non-central locations. This paper uses an example where these prices exist to test the hypothesis. The evidence, from the late nineteenth century corn markets in Chicago and New York, strongly supports the conjecture.
