abstract:In financial economics, a state-price security, also called an Arrow-Debreu security (from its origins in the Arrow-Debreu model), is a contract that agrees to pay one unit of a numeraire (a currency or a commodity) if a particular state occurs at a particular time in the future and pays zero numeraire in all the other states. The price of this security is the state price of this particular state of the world, which may be represented by a vector.
