In financial economics, a state-price security, also called an Arrow–Debreu security (from its origins in the Arrow–Debreu model), a pure security, or a primitive security 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.
A security deposit is a sum of money held in trust. [ 1 ] In leasing, security deposits, also known as "rent deposits", [ 2 ] are required most often by lessors of automobiles , residential property, and commercial real estate .
Loans create deposits: for the banking system as a whole, drawing down a bank loan by a non-bank borrower creates new deposits (and the repayment of a bank loan destroys deposits). So while the quantity of bank loans may not equal deposits in an economy, a deposit is the logical concomitant of a loan – banks do not need to increase deposits ...

[1]In financial trading, a position in a futures contract does not reflect ownership but rather a binding commitment to buy or sell a given number of financial instruments, such as securities, currencies or commodities, for a given price.
In mathematical economics, the Arrow–Debreu model is a theoretical general equilibrium model. It posits that under certain economic assumptions (convex preferences, perfect competition, and demand independence), there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy.
Sonnenschein-Mantel-Debreu theorem (SMD theorem) is a theorem for exchange economy that can be expressed in the following way: . for a function that is continuous, homogeneous of degree zero, and in accord with Walras's law,there is an economy with at least as many agents as goods such that, for prices bounded away from zero, the function is the aggregate demand function for this economy.
