A new form of lending using digital collateral has recently emerged, most prominently in low and middle income countries. Digital collateral relies on ``lockout" technology, which allows the lender to temporarily disable the flow value of the collateral to the borrower without physically repossessing it.

Standard models assume that transactions are executed once the buyer and seller agree on a price. In practice, there is usually a period of ``due diligence" after terms have been negotiated but prior to execution. We analyze such a model. We show that the acquirer engages in “too much” due diligence relative to the social optimum. Nevertheless, allowing for due diligence can improve both total surplus and the seller’s payoff compared to a setting with no due diligence. [Slides]
