snqProfitShadowPrices | R Documentation |
Shadow Prices of a SNQ Profit function
Description
Calculates the shadow prices of a Symmetric Normalized Quadratic (SNQ)
profit function.
Usage
snqProfitShadowPrices( priceNames, fixNames, estResult = NULL,
data = estResult$data, weights = estResult$weights,
scalingFactors = estResult$scalingFactors,
coef = estResult$coef, form = estResult$form )
Arguments
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).

germanFarms$qLabor <- -germanFarms$qLabor
germanFarms$time <- c( 0:19 )
priceNames <- c( "pOutput", "pVarInput", "pLabor" )
quantNames <- c( "qOutput", "qVarInput", "qLabor" )
fixNames <- c( "land", "time" )
estResult <- snqProfitEst( priceNames, quantNames, fixNames, data = germanFarms )
