The rationale of this chapter is the same as for the last chapter of the first volume of the book. We leverage the technology developed in the second volume to revisit some of the examples introduced in Chapter (Vol I)-1, and complete their mathematical analysis. We use some of the tools introduced for the analysis of mean field games with a common noise to study important game models which are not amenable to the theory covered by the first volume. These models include extensions to games with minor and major players, games of timing, and some finite state space models. We believe that these mean field game models have a great potential for the quantitative analysis of very important practical applications, and we show how the technology developed in the second volume of the book can be brought to bear on their solutions.
