The social accounting matrix (SAM) approach to representing an equilibrium system is yielding results. One is forced to account simultaneously for values of products and inputs for the complete system. In a contribution to a Gardner Brown "Advances" volume, I discovered a strange washing out of natural capital value on the input side when proper depreciation of non-renewing capital was valued on the product side. Geir Asheim and I have another version of this valuation anomaly forthcoming in Ecological Economics. The SAM approach is useful also in exploring the idea that most of government product is intermediate, rather than final "consumption". Interesting also is much government product as investment in durable government capital. I presented these arguments at the Canadian Economics Association annual meeting in Ottawa in June, 2011. My estimate of a personal discount rate for a representative individual (3.8%) based on an uncertain number of remaining years of life and on the Murphy-Topel "values of life years" is forthcoming in Economics Letters. And I have been kept busy over the past nine months, writing up my course notes for Urban Economics into a textbook, spurred on by a publisher's rep." (August 10, 2011)
