snqProfitShadowPrices: Shadow Prices of a SNQ Profit function

In micEconSNQP: Symmetric Normalized Quadratic 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).
