We consider a price discrimination problem in which a seller has a single object for sale to a potential buyer. At the time of contracting, the buyer's private type is his incomplete private information about his value, and the seller can disclose additional private information to the buyer. We...

Dealers mitigate search frictions in over-the-counter markets by forming trading networks. The MSRB Transaction Reporting System audit trail shows the dealership network in municipal bonds is sparse and has a tiered core-periphery structure. Bonds are intermediated in chains in which central...

In this paper we focus on a long-term dynamic analysis of the optimal adaptation/mitigation mix in the presence of a pollution threshold above which adaptation is no longer efficient. We account for accumulation in abatement capital, greenhouse gases, and adaptation capital in order to better...

In this work we establish a one to one correspondence between the adjoint states appearing in the stochastic Pontryagin principle and the Lagrange multipliers associated to the abstract optimization problem. Using this identification we provide some sensitivity results for the optimal cost in terms...

We study the network of co-authorship among economists. This network is expanding: the number of authors is growing but the distance between them is shrinking: economics is an emerging small world. We find that network structure has powerful effects: closer-by authors in the network are much more...

We provide a framework with multiple worker types (e.g. gender, age, education) to decompose changes in aggregated and disaggregated measures of between-group inequality into changes in (i) the composition of the workforce across labor types, (ii) the importance of different tasks, (iii) the extent...

We study the asymptotic inference for a conditional moment equality model using highfrequency data sampled within a fixed time span. The model involves the latent spot variance of an asset as a covariate. We propose a two-step semiparametric inference procedure by first nonparametrically recovering...

Shape constrained nonparametric estimation dates back in the 1950's. In his milestone paper in 1956, Grenander found the maximum likelihood (ML) estimator of a nonincreasing density, whereas Brunk (1958) obtained the least squares estimator of a monotone regression function. After the derivation of...

We propose a model of posted prices in networks. The model maps traditional concepts of market power, competition and double marginalization into networks, allowing for the study of pricing in complex structures of intermediation such as supply chains, transportation networks and decentralized...
