Price Discovery in Private Negotiation Trading with Forward and Spot Deliveries
Posted: 20 Sep 2006
Advance production in spot markets increases seller costs because inventories must be held. This cost does not exist in production-to-demand (or forward) markets, for which production follows trading, and sales exactly match quantities produced. Data from laboratory-computerized markets that trade through private negotiation are analyzed. For the experimental supply and demand conditions, price convergence patterns show spot prices 10.8% lower and the number of trades 12.4% fewer than forward outcomes. The adverse impact of advance production and private negotiation on seller earnings is emphasized when earnings are compared with those from double auction trading.
