I extend Myerson's (1981) ironing technique to more general objective functions. The approach can be used to solve quasilinear principal-agent models with a one-dimensional type in the general case where the monotonicity constraint implied by incentive compatibility may be binding at the...

We study mechanism design in dynamic quasilinear environments where private information arrives over time and decisions are made over multiple periods. We make three contributions. First, we provide a necessary condition for incentive compatibility that takes the form of an envelope formula for...

This paper examines the problem of how to design incentive-compatible mechanisms in environments in which the agents' private information evolves stochastically over time and in which decisions have to be made in each period. The environments we consider are fairly general in that the agents'...

two mechanisms that implement the same allocation rule must yield the same expected payoffs to the agents and hence the same expected revenue regardless of the transfer scheme and of the information disclosed by the mechanism to the agents. We then use the result as a tool for designing profit...

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."
