Some Extensions



In this final chapter we will introduce, without pretending to be exhaustive, a number of extensions to the basic theory developed in chapters 3 through 6. The models discussed in these chapters either condition on quantities or on prices. In the first section we will therefore look at models which avoid this dichotomy, and at the same time pave the way towards further generalizations. A strong restriction built into the foregoing theory is that inputs and outputs as such do not change through time. However, in reality we encounter quality change as well as disappearing and newly emerging inputs and outputs. The second section and the third section, respectively, are devoted to theoretical approaches for coping with these problems. All of these sections are by nature only indicative and hopefully helpful for those wishing to do further research.
