Regional Sewer System Rate Structure Study.

This 1992 report is the first of three research projects focusing on factors affecting the socio-economic vitality of the Fully Developed Area (FDA) in context with overall development patterns of the Twin Cities Metropolitan Area.Prepared under contract # C-93-32 for the Metropolitan Council

Phenomenology of the deuteron electromagnetic form factors

A rigorous extraction of the deuteron charge form factors from tensor polarization data in elastic electron-deuteron scattering, at given values of the 4-momentum transfer, is presented. Then the world data for elastic electron-deuteron scattering is used to parameterize, in three different ways, the three electromagnetic form factors of the deuteron in the 4-momentum transfer range 0-7 fm. This procedure is made possible with the advent of recent polarization measurements. The parameterizations allow a phenomenological characterization of the deuteron electromagnetic structure. They can be used to remove ambiguities in the form factors extraction from future polarization data

Maximizing, measuring, and not double counting transportation-improvement benefits: A primer on closed- and open-economy cost-benefit analysis

In a "closed-economy" cost-benefit analysis of a public investment, all affected economic agents matter. In such an analysis, if price equals marginal cost in all affected markets, accurately measuring benefits requires looking only at the use made of the improvement; "non-user" costs and benefits cancel out. Only if price is unequal to marginal cost in affected markets do unduplicated net nonuser benefits and costs exist. In an "open-economy" cost-benefit analysis, gains and losses to outsiders are ignored. The nature of nonuser insider benefits, particularly from "job-creation", is discussed.
