We investigate a general class of dynamical open-bid combinatorial auction protocols termed price-demand procedures, where the auctioneer asks buyer-dependent price vectors and buyers reveal demand sets. Such revelations are easier to practice than the revelations of entire valuations at once....

This paper demonstrates the theoretical foundation that underlies the willingness of rational arbitrageurs to delay and reinforce the speculative attack. The key assumptions are that there is a small probability that arbitrageurs are behavioral and never time the market of their own accord and...

We incorporate social influence into implementation theory, and highlight the manner in which an informed agent feels guilty with regard to disobeying an uninformed principal’s wishes. The degree of this feeling depends on the agent’s expectation of others’ behavioral modes. We demonstrate...

This paper shows the experimental results for multi-object auctions in terms of efficiency, revenue, and bidders' payoffs. We assume that there are two heterogeneous objects and two bidders, and that each bidder does not know the other bidder's material payoff structure. We conducted the...

We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) [20] that restricts the message spaces. The...

This paper investigates the possibility that an unproductive company with limited debt capacity raises huge funds through share issuances by utilizing a small sign of enthusiasm. We generalize the timing game of Matsushima (2012) by permitting arbitrageurs to use high leverage for purchasing the...
