A budget-constrained buyer wants to purchase items from a short-listed set. Items are differentiated by observable quality and sellers have private reserve prices for their items. The buyer's problem is to select a subset of maximal quality. Money does not enter the buyer's objective function,...

We study the dynamic mechanism design problem of a seller that repeatedly auctions independent items over a discrete time horizon to buyers that face a cumulative budget constraint. A driving motivation behind our model is the emergence of real-time bidding markets for online display advertising...

Market distress can be the catalyst of a deleveraging wave, as in the 2007/08 financial crisis. This paper demonstrates how market distress and deleveraging can fuel each other in the presence of adverse selection problems in asset markets. At the core of the detrimental feedback loop is agents'...

In a simple risk-sharing environment with ex post private information, conditions are found under which a collateralized debt contract is the optimal allocation. The critical condition for optimality is that the borrower values the collateral good more highly than does the lender; otherwise the...

There is growing empirical support for the conjecture that access to credit is an important determinant of firms' export decisions. We study a multi-country general equilibrium economy in which entrepreneurs and lenders engage in long-term credit relationships. Financial constraints arise in...
