Virtual implementation in backwards induction

We examine a sequential mechanism which is a simple modification of the normal form mechanism introduced by Abreu and Matsushima (1992). We show that almost any social choice function can be virtually implemented via a finite sequential game of perfect information. The solution concept assumed is backwards induction. In particular, any social choice function that is virtually implementable via the Abreu-Matsushima mechanism is also virtually implementable by a sequential mechanism.
