snqProfitShadowPrices {micEcon} | R Documentation |
Calculates the shadow prices of a Symmetric Normalized Quadratic (SNQ) profit function.
snqProfitShadowPrices( priceNames, fixNames, estResult = NULL, data = estResult$data, weights = estResult$weights, scalingFactors = estResult$scalingFactors, coef = estResult$coef, form = estResult$form )
priceNames |
a vector of strings containing the names of netput prices. |
fixNames |
an optional vector of strings containing the names of the quantities of (quasi-)fix inputs. |
estResult |
object returned by snqProfitEst . |
data |
a data frame containing the data. |
weights |
vector of weights of prices used for normalization. |
scalingFactors |
factors to scale prices (see details). |
coef |
a list containing the coefficients (at least delta and gamma). |
form |
the functional form to be estimated (see details). |
