Product Optimization in Stepwise Design

open access: yes, 2021
Stepwise design of programs is a divide-and-conquer strategy to control complexity in program modularization and theorems. It has been studied extensively in the last 30 years and has worked well, although it is not yet commonplace. This paper explores a new area of research, finding efficient products in colossal product spaces, that builds upon past ...

Optimal Advertising for Information Products [PDF]

open access: yesProceedings of the 22nd ACM Conference on Economics and Computation, 2021
When selling information products, the seller can provide some free partial information to change people's valuations so that the overall revenue can possibly be increased. We study the general problem of advertising information products by revealing partial information. We consider buyers who are decision-makers.
