We introduce labour contracts in a framework of optimal redistribution: firms have some local market power and try to discriminate among heterogeneous workers. In this setting we show that if the firms have perfect information, i.e, they perfectly discriminate against workers and take all the...

In this note we show that the equilibrium characterized by Biais, Martimort and Rochet (Econometrica, 2000) could have been characterized by direct mechanisms even if the Revelation Principle does not apply in their setting. The use of more sophisticated mechanisms, such as menus, was not necessary

Using a common agency framework, we characterize possible equilibria when annuities contracts are not exclusive. We discuss theoretical and empirical implications of these equilibria. First, we show that at equilibrium prices are not linear. Then we characterize an equilibrium. We provide...

We consider an exchange economy in which a seller can trade an endowment of a divisible good whose quality she privately knows. Buyers compete in menus of non-exclusive contracts, so that the seller may choose to trade with several buyers. In this context, we show that an equilibrium always...

Many financial markets rely on a discriminatory limit-order book to balance supply and demand. We study these markets in a static model in which uninformed market makers compete in nonlinear tariffs to trade with an informed insider, as in Glosten (1994), Biais, Martimort, and Rochet (2000), and...

Consider a seller of a divisible good, facing several identical buyers. The quality of the good may be low or high, and is the seller's private information. The seller has strictly convex preferences that satisfy a single-crossing property. Buyers compete by posting arbitrary menus of contracts....
