In this paper, we propose an extension to the DAB model, called the multi-unit differential auction barter (MUDAB) model for e-marketplaces in which multiple instances of commodities are exchanged.
If firms are pricing at marginal cost, and costs (of commodity inputs, for instance) are bouncing around, then prices shift together in a perfectly competitive industry, just as they might in a cartel.
"As opposed to other instances of sharp increases in agricultural commodity prices that have rapidly dissipated, we could be facing higher prices for some time".
On the other hand, our approach can scale to handle a very large number of parameters by simply increasing the number of commodity computational nodes (for example by increasing the number of instances on an Amazon Web Services cluster).
The approach proceeds by improving a given feasible solution by solving restricted instances of the problem where flows of certain commodities are fixed to those in the solution while the other commodities are locally optimized.
Mr. Resnick is head of commodity trading.
Forget the regulation of commodity prices.
Board of Trade, Organized market for the exchange of commodity contracts (see commodity exchange).
The currencies of commodity producers, he says, should follow commodity prices.
