However, the possibility to counterfeit ?at money can affect its value, velocity, output and welfare, even if no counterfeiting occurs in equilibrium. We provide two extensions of the model under which the threat of ...

We assume that agents can produce fraudulent assets at a positive cost, which generates endogenous upper bounds on the quantity of each asset that can be sold, or posted as collateral in the OTC market. Each endogenous, asset-specific, resalability constraint depends on the vulnerability of the asset to fraud, on the frequency of trade, and on the current and future prices of the asset. In ...
