Abstract. Due to long procurement lead-time,
suppliers typically decide on capacity, such as the purchase of a
critical component, before the final production at the manufacturer’s
site. Under such a production scheme, the initial capacity decision has
significant impact on the profits, in particular for short product life
cycle industries, such as fashion and high-tech. To make the right
capacity decision, it is crucial for the supplier to have accurate
demand information. It is often the case, however, that manufacturer
has more accurate forecast. To make the matters worse, she also has
every incentive to inflate the forecast to secure more capacity if the
supplier were to ask for her forecast information.
In this talk, we will present a model for a supply chain that faces the
above problem. We will address how different contracts affect the
optimal capacity decision and hence the profitability of the supplier
and the manufacturer. In particular, we will consider four contracts --
the wholesale price contract, the pay back contract, the capacity
reservation contract, and the advance purchase contract. The wholesale
price contract is the most prevalent contract in practice because of
its simplicity. But the simplicity comes with a price: it does not
achieve credible information sharing, hence resulting in high
inefficiency. Advance purchase contract enables the manufacturer to
signal her forecast update (a signaling game) while the capacity
reservation contract enables the supplier to “smoke out” this
information from the manufacturer (a mechanism design). Both of them
achieve credible information sharing hence improving the efficiency of
the system. But which is better depends on the problem setting such as
degree of forecast information asymmetry and the capacity acquisition
cost.
