Auctions (especially multi-object auctions), real options in competitive situations

Recent Thoughts

【Practical approach】 Through my work at VCASI, I hope to gather practitioners from a variety of fields who face problems related to auctions and bidding, such as businessmen and those involved in public policy, and hold tutorials and conferences. While sharing their problems, I also want to convey to them, without using mathematics, the essence of mechanism design and auction theory.
【Theoretical issues】 Strategic quasisupermodularity (quasi-supermodularity), in the weak sense, is established in auctions dealing with a single object, allowing for the development of the theory of equilibrium analysis. I think it might be possible to apply this idea to multi-object auctions. I also want to develop applications for a Markov game with strategic fungibility related to models for evaluating investments in competitive situations.
