We re-visit the proposition: utility-change for the translog utility function equals the corresponding Tornqvist quantity index. We observe that the "linear" terms in the translog function must be zero for the result to obtain. We also report on the role of the assumption of homogeneity for the...

We account for the price and quantity components of a decomposition of the expression for a GDP increase accross periods. Our linear measure is compared with Irving Fisher's multiplicative measure. Where technical progress enters is noted.

We take up three variants of Solow [1974], each with population change endogenous. When each model exhibits sustainability the same three conditions are satisfied: (i) investment in produced capital is funded by resource rents plus "extra" saving, (ii) "extra" saving funds the same two gaps...

We "translate" Hotelling's continuous-time, exhaustible resource extraction Model of 1931 into a linear program of present value extraction cost minimization subject to a stock endowment and period by period demand constraints. The appropriate form of the demand constraints allows for resource...
