Contingent valuation.A survey-based economic technique for the valuation of non-market
resources, such as environmental preservation or avoidance of air pollution health risk.
Control scenario.In a modeling study, this is a sensitivity scenario in which emissions from one
or more source sectors are changed (increased or decreased), from a given “baseline scenario”.
The subsequent modified emissions are then used within an air quality model to derive new
ambient concentrations. Control scenarios are used to assess the efficacy of proposed emissions
controls for sources of pollution.
Cost of Illness (COI).The cost of illness includes the direct medical costs and lost earnings
associated with illness. These estimates generally understate the true value of reductions in risk
of a health effect, as they include just the direct expenditures related to treatment and lost
earnings, but not the value of avoided pain and suffering from the health effect.
C-R Function. See Concentration-Response (C-R) Function.
Currency year.The value of the dollar based on the year specified. Typically, you would adjust
the valuation estimate to a consistent currency year. For example, you might want to report the
valuation estimate in 2000 dollars to make it easier to compare with your cost analysis, which
uses that same currency year.
