I don't have a clue what this means either. To my knowledge, Marxian labour-values can be measured statistically only indirectly, as: 1) observed quantities of labour-time worked. 2) observed exchange ratios of products. 3) observed or derived money-prices of products, of some description. Often measurement of Marxian values occurs via some proxy variables, thought to reflect closely what product-values are. However, national accounts definitions of gross and net output do not necessarily reflect "real" output prices realised, because they are adjusted (ideal) prices, reflecting an accounting concept of "production", and an accounting concept of "value-added", i.e. a particular view of what costs and revenues should be included in the calculation, and how they should be valued. Consequently, measurements based on official input-output data are at best an approximate indicator of real economic trends. Kliman seems to want to argue that there is no strong correlation between values and prices, but even if this could be proved, I think it would undermine the Temporal Single System approach. Jurriaan
