Eric Maskin shared the 2007 Nobel Memorial Prize in Economics for his work in Mechanism Design Theory. This is the study of how, given an economic or social goal, we can design a procedure or institution (that is, a mechanism) for achieving that goal. In this lecture, he gives an introduction to mechanism design using several simple examples.

In such mechanism, to design an ith toggle configuration for an ith active input, it is required to freeze all but the ith input. Stoppers are the means of arresting the undesirable (n-1) inputs. Moreover, the active single d.o.f. mechanism can have a wide range of motion in its configuration space. The stoppers are responsible for implementing ...
