Traditionally, mechanisms have been designed manually. That is, the designer identifies the characteristics that she would like in her mechanism, and then mathematically designs the mechanism. This had led to a number of standard well-known mechanisms that perform quite well. However, there are a number of disadvantages to these mechanisms. Many mechanisms (e.g. the VCG Mechanism) maximize soci...

While travelers' desire to visit the world's most remote places has grown, inefficiency of global payments indicates a significant barrier tourism growth. As an emerging, decentralized, and borderless digital innovation, Bitcoin technology seems have ability serve as payment alternative address such fundamental inefficiencies.

We model asymmetric information arising from physician agency, and its effect on the design of payment and healthcare quantity. The physician-patient coalition aims to maximize a combination of physician profit and patient benefit. The degree of substitution between profit and patient benefit in the physician-patient coalition is the physician’s private information, as is the patient’s intrinsi...

In this context, optimizing payments within the Groves class has recently received much attention, mostly under the assumption that agent’s private information is single-dimensional. Our work tackles this problem in multi-parameter...
