We consider a model of price competition and collusion with private monitoring. The sellers have homogeneous good, and the buyer has a unit demand every period over an infinite horizon. The buyer's valuation is his private information, and the sellers start with a common prior. The seller only...

I show how agents' involvement in imperfect financial markets can be welfare improving when the government lacks the ability to commit to a tax policy over time. Agents borrow against their promised income in markets that are incomplete in the sense that claims cannot be resold without loss. Taking...

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...
