One can easily get the impression that the α- and β-construction are the only ones of interest.

,Das stationäre elektrische Strömungsfeld,In this chapter we commence a discussion of implementation in cooperative equilibria; we shall consider the most important case, that of strong Nash implementation. Only little is known about implication in other types of equilibria.

Stability,In this chapter, we start our discussion of the application of effectivity functions. These applications were sketched already in the previous chapters: effectivity functions describe the power structure in a society by stating what each coalition of individuals can achieve by concerted action.
