Monotone Comparative Statics for Equilibrium Problems

  title={Monotone Comparative Statics for Equilibrium Problems},
  author={Alfred Galichon and Larry Samuelson and Lucas Vernet},
We introduce a notion of substitutability for correspondences and establish a monotone comparative static result, unifying results such as the inverse isotonicity of M-matrices, Berry, Gandhi and Haile’s identification of demand systems, monotone comparative statics, and results on the structure of the core of matching games without transfers (Gale and Shapley) and with transfers (Demange and Gale). More specifically, we introduce the notions of unified gross substitutes and nonreversingness…

Connected Substitutes and Invertibility of Demand

We consider the invertibility (injectivity) of a nonparametric nonseparable demand system. Invertibility of demand is important in several contexts, including identification of demand, estimation of

The Implementation Duality

We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear

Ascending Auctions with Package Bidding

Abstract A family of ascending package auction models is introduced in which bidders may determine their own packages on which to bid. In the proxy auction (revelation game) versions, the outcome is

The unreasonable effectiveness of optimal transport in economics

A brief review of the basics of the theory of optimal transport, its applications to economics, and some extensions are offered.

The Strategy Structure of Two Sided Matching Markets

We study two-sided markets in which agents are buyers and sellers or firms and workers or men and women. The agents are to form partnerships (which provide them with satisfaction) and at the same
