This is the formula that was used for the old Financial Times stock market index (the predecessor of the FTSE 100 Index). It was inadequate for that purpose. In particular, if the price of any of the constituents were to fall to zero, the whole index would fall to zero.
The trade-weighted FAO Food Price Index is technically a price index and is calculated using the Laspeyres formula. It documents the development of world market prices of 24 agricultural commodities and foodstuffs in U.S. dollars.

If the supply price exceeded the demand price ...
In commodities transactions, formula pricing is an arrangement where a buyer and seller agree in advance on the price to be paid for a product delivered in the future, based upon a pre-determined calculation. For example, a packer might agree to pay a hog producer the average cash market price on the day the hogs will be delivered, plus a 2 ...
