Can unit values be negative? When they are positive, why are they positive?

The unit values of sold commodities must be positive because they are sold for
an equivalent sum of money whose value is positive. This applies to flows.
Stocks of commodities that are not currently being sold but will be sold
eventually will also have positive unit values. But stocks that will never be
sold could have negative or zero unit values. Indeed, they must have.

Consider a simple model with traditional agriculture. At the beginning of the
final period there is a positive physical stock of corn. At the end the
physical stock is zero, as is its value, and no corn has been sold.  However,
labour has been performed and value added is positive and must be equal and
opposite to the value of the opening stock of corn to give zero sales and
closing stock.
