We develop a model of misinformation wherein users' decisions to verify and share news of unknown truthfulness interact with producers' choices to generate fake content as two sides of a market that balance to deliver an equilibrium prevalence and pass-through of fake news. We leverage the...

Two activists with correlated private positions in a firm's stock, trade sequentially before simultaneously exerting effort that determines the firm's value. We document the existence of a novel linear equilibrium in which an activist's trades have positive sensitivity to her block size, but...

We study dynamic signaling when the informed party does not observe the signals generated by her actions. A forward-looking sender signals her type continuously over time to a myopic receiver who privately monitors her behavior; in turn, the receiver transmits his private inferences back through...

We find a necessary and sufficient condition such that a distributional upgrade on a seller’s cost implies a lower expected procurement cost for a buyer. We also show that even under the strongest assumption about this upgrade made in the literature so far, the seller can be worse off, even if...

In this paper we characterize the optimal procurement mechanism and the investment level for an environment where two projects must be adjudicated sequentially, and the winner of the first project has the opportunity to invest in a distributional upgrade for its costs in the second project. We...

We develop a continuous-time model of career concerns that incorporates human capital accumulation throughout the working life. Workers are able to generate an output that follows a diffusion process with a drift that is the sum of effort and ability ("talent"). Talent corresponds to a hidden...
