We study users' response to sponsored-search advertising using data from Microsoft's Live AdCenter distributed in the 'Beyond Search' initiative. We estimate a structural model of utility maximizing users, which quantifies 'user experience' based on their 'revealed preferences' and predicts user...

These notes examine the problem of how to extend envelope theorems to infinite-horizon dynamic mechanism design settings, with an application to the design of bandit auctions.

We examine the design of incentive-compatible screening mechanisms for dynamic environments in which the agents' types follow a (possibly non-Markov) stochastic process, decisions may be made over time and may affect the type process, and payoffs need not be time-separable. We derive a formula...
