By 1930 the valley was loading twenty thousand refrigerator cars of lettuce a year without knowing what any would sell for. The old consignment system invited fraud, which Congress criminalized in 1927 and regulated in 1930. A federal price wire, brokers, and sales made at the shed shifted the risk onto the grower-shipper. Stanford economist William O. Jones studied exactly this, then applied the same questions to African food markets.

Still debated
The exact title of Jones's dissertation is unverified, and the specific argument of his 1951 paper was not checked against the full text. Whether diversion of unsold cars in transit was as central to lettuce as to citrus, and the usual diversion points, could not be verified.
