Standard discrete choice models used to evaluate mergers assume that different product varieties are substitutes. However, legal defences in some recent high-profile mergers rested on demand complementarity (e.g., GE/Honeywell). Since complements tend to be priced lower by a monopolist than by a...

We propose a new analysis of Piyavskii's algorithm for deterministic or stochastic Lipschitz global optimization. More precisely, we address the problem of finding a global maximizer of a (locally) Lipschitz function f on [0,1]^d with known Lipschitz constant, using as few (possibly noisy)...

Procurement auctions have been successfully applied in a variety of settings. We study optimal procurement mechanisms for a buyer with a fixed budget that wishes to purchase units of a homogeneous good, up to a maximum demand amount, from symmetric suppliers with privately known constant marginal...

We introduce a new approach to bargaining, with both axiomatic and strategic foundations, into models of decentralized asset market. Gradual bargaining, which assumes that portfolios of assets are sold sequentially, one unit of asset at a time, has strong normative justifications: it increases the...

L'objectif du TSE Student Workshop est de présenter les travaux des doctorants de TSE et de favoriser les interactions entre chercheurs et doctorants. Pendant cette journée, des étudiants sélectionnés auront l'occasion de présenter leur travail (20 minutes) qui sera discuté dans un second temps (5...

The problem of variable clustering is that of grouping similar components of a $p$-dimensional vector $X = (X_1 , \ldots , X_p)$, and estimating these groups from $n$ independent copies of $X$. Although K-means is a natural strategy for this problem, I will explain why it cannot lead to perfect...

Decentralized implementation of development programs is typically motivated to increase accountability and use of local information by service providers. Most developing countries have delegated implementation to elected local governments. However this has created problems arising from elite...
