In economics, work on diverse technologies, e.g., Crew and Kleindorfer (1976), characterizes efficient production decisions and technology mixes under competition and price uncertainty, but this work does not consider contract and spot market interactions. In industrial organization, previous work on forward-spot integration, e.g., Allaz and Vila (1993) neglects either capacity constraints, spot price uncertainty, options, or heterogeneous technologies.…”
