Correct PAGE09 damage component parameters #33

Closed pwaidelich closed 5 years ago

pwaidelich commented 5 years ago

The old PAGE09 damage component is currently using zero-value parameters which would result in zero damages if this component was used for market damages. According to the PAGE-ICE excel file, W_MarketImpactsatCalibrationTemp is Triangular(0.2, 0.6, 1), resulting in a mean of 0.6. ipow_MarketIncomeFxnExponent is Triangular(-0.3, -0.1, 0), resulting in a mean of -0.1333 iben_MarketInitialBenefit is Triangular(0, 0.1, 0.3), resulting in a mean of 0.1333

I checked these values against anthofflab/MimiPAGE2009.jl but they have W_MarketImpactsatCalibration at 0.5 with a Triangular(.2, .5, .8). So apparently, this was updated as part of PAGE-ICE.

Probably my fault: the Excel file is set to replace those values with zeros when the Burke economic impact is chosen, so I just pulled those values. This looks fine to me. Feel free to merge it.
