Ian, I have learned a lot from Semmler, D&L - really impressive work. But still something is missing. I cannot point to anything closer to my own views in terms of mathematical or simulation models. I am now looking for simulation models/tools, but I have not had much time to do this properly, so I cannot offer much real substance, but that's my research agenda, besides more conceptual debates. There are some models inspired of Nelson and Winter (1982), but that's totally devoid of explicit value theory - which make these models less relevant for us. All hints about possible simulation models/tools are very welcome. Regards Anders At 21:47 13.03.2007, you wrote: >Hi Anders > >I am in complete sympathy with your methodological advice.
